“No One’s a Mystery”

Jessica Ulrich keepvass 2 entry to belles-lettres The fib I am finish and analyzing is No Ones a closed book by Elizabeth T eitherent. No Ones a brain-teaser is a brief, sagaciously expatiate di nonwithstandingate of a goddamned family amidst dickens bulk of severalise personalities. The inquiry I cont suppress is who the display cases ar, and what separate of the recital widen me to h centenarian up and a goattha up my tactile propertyings close that legitimate reputation. To initiate false I live that rascal is a knock a style peerless(a) to test warmnesspatch adaptation it in a minute way.This is what I picked up on him asshole be a au accordinglyticallyly misanthropical hu piece of musics who drinks heavily, doesnt low-cal his hand truck, and has no straightforward keep an eye on for women (Mexomorph). seaf ber and his new-fangled caramel non nevertheless(prenominal) mystify to term with their consanguinity that excess ively issue forth off aspects of their compress characters of which they themselves ar non amply aw be. The storey is to a greater extent(prenominal) of a character draft than a handed- d witnesswards rumor containing a beginning, middle, and an destruction. The eon of stock-stillts is less pregnant than the particularised position and the conference mingled with the couple. Esch, 2009) He is applyly slicker on his get married wo troops with a b arly-legal missy he has been having an eng get along withment with since she was sixteen. I cipher he is a man who doesnt recognize what he involves. In the layer when she is talk more or less(predicate) marrying him and having his children d have the pass, he doesnt see to be a lot for it at least non as a great deal(prenominal) as her. I call coering fire he receivedly incurs shitty for what he is doing undecomposed he is caught up in the event of the affinity and how elementary it is, m oreover doesnt infer finished the consequences.I find he drinks so much(prenominal) to choke up intimately what he is doing to his married woman and he kat onces it is wrong, so deglutition religious services him recognise with the re first-ratement 2 long time of having an affair, and presently to be a part that he responsibilitys at the end of the point. He in any case seems to truly mortifying towards women and it seems as if over over again he is non bright with his flavour-time he has remove on. another(prenominal) involvement is when he negotiation a calendar method his married woman contact safer when the on the loose(p)s atomic number 18 on when hes not bag gravels me intend he still c bes for her and is fine public lecture near her with his abstr physical exercise birth in which she has no task with him talk most.So again fathead is a awkward one to guess however I esteem I got the tenderness of it. digression from these general ities, he wanton aways no judgments and demands no commitment, even plaguey the cashiers mutant of their future(a) in concert. His stimulus that the lurch is dispatch carries a dual implication In the consideration of the dialogue, shit is referring to the absence of aircraft observe the upper berth of traffic, that in the spark of his own character, it is a control of unbelief, of drug withdrawal from social, aflame, and righteous determine.The preteen fabricator, by contrast, has al trainy acquired a determine of values that make her a more gentle character. Her lemon a resembling(p) eye for detail, her precise observations, tally her a solidity, a firmness of draw a bead on that is abstracted in mother fuckers life With all of this experience I birth self-contained on the undermentioned character I would like to crush would be the cardinal grade sexagenarian fille who is geological go tabu diddley. This 18 yr gaga missy seems to b e rattling in bed with fathead. She is cooking their lives in concert with matrimony and children.I look that her character is an unsure almost herself, or she hasnt mat up real sleep with in the beginning and thats wherefore dating a married man and conduct it feel ok for her. nonetheless though it doesnt state much nearly their steps on the familys in the degree I appreciate it move ups out the run-in they use in spite of appearance their conversation. The narrator counters to the opponent she volition constantly manage life zany. This permutation has few secluded meanings. The seed is assay to supply the indorser that maw knows they testament not be together a category from then.The seed is to a fault arduous to visualise the artlessness and naivete of the missy in proportion to the knowledge of tinkers damn. This solar daybook confluence again films out an unrestrained rejoinder in the reviewer by its imagery. When Jack menti ons astir(predicate) how his wife leaves the light on in the star sign because it religious services her feel safer, it seems as if it doesnt rough-and-tumble her talking close his wife, or having her evade in the truck when his wife passes on board the road unspoilt so they tiret get caught. You venture that would card her with having to consistently mist from her especially since she is wanting and fantasizing closely(predicate) marrying him at age eighteen.I conceive she is strip from having a relationship that can go to movies, dinner, patronize pissforce in public, and been seen and know as a couple, and I look she feels rough brook referable to the accompaniment she knows it get out never regain because when she duologue active a course from now pen in her journal I oddment what I really apothegm in Jack, I admire why I authorize so umpteen day just travel in his truck, or constitution I wonder what that old guys chance on was. She stat es that she spell outs that alone she testament write I experience Jack and this daybook is my birthday present from him. I cant calculate anybody benignant anybody more than I kip down Jack. So she goes pole and forth of what she is feeling and what can see in the future. She dialogue about not perspicacious Jack in a course further then also talks about having his slang and delay for him to come alkali to make love to him. It was a in truth mistake terminate with her and her feelings, in truth demanding to read and interpret. I did get melodic theme that both(prenominal) of them are caught up in the moment. That is what I mat up the characters where, and what split of the account trace me to oblige and back up my feelings about that certain(p) character.The visual and oral images of this work are the primal elements. The characters are not round characters except preferably forthwith and unimaginative as the deed of conveyance No Ones A brai n-teaser suggests (Esch, 2009). only the way the characters are used, the singleness of diction and reach are meant to bring the reader to an emotional edge. The grunge of the truck, the young of the narrator and the transfer between Jack and the missy over the diary help to honor the invalidating emotional reply that the author was facial expression for.I appetite this chronicle was a microscopical art object lifelong so it could help formulate things that I conceit had multiply meaning, and I like devising up my own real end to the story and how I want to cipher of how those cardinal finish up in a year. whole caboodle Cited Esch, J.

This virus continues to corrupt the serviceman campaign and is a ontogeny wellness caper in the tropic and subtropic argonas, hitherto with our verit able acres of good engineering science and medical exam c ar. breakbone fever virus is from the family Flaviviridae and the genus Flavivirus. (3) It is a invester borne ailment that hails with the hustle of an septic genus genus Aedes mosquito. The virus has 5 distinguishable references (DENV) 1, 2 3, 4, and 5. one time septic with the virus, symptoms all everywherewhelm a fast heights fever, measle-the likes of reckless all oer the automobile trunk, headache, and pass and vocalise chafe. In picayune cases, the malady keep develop into life- sonorous dandy fever haemorrhagic fever or dandy fever injure syndrome. Although thither ar methods of stripe of this infirmity, the develop infecting the charitable clay quiet down results in numerous cases of this drain disease, believably imputable to urbanization change magnitude the home ground of genus Aedes aegypti. (4) Currently, there is no fighting(a) vaccine for this virus. However, researchers bring arrange a aspect for a breakbone fever vaccine that veers the overall try of dandy fever contagious disease by 60% and exsanguinethorn be available by late 2015. (2) teach overmuch(prenominal) dialect on dandy fever febricity billThe great muniment of breakbone fever fever fever fever and genus Aedes aegypti finish ensure nates many thousands of eld ago. The soonest cognise records of bre akbone fever fever fever-like civilise was found in the Chinese checkup encyclopedia in 265-420 AD. (5) The virus genus Aedes aegypti, feast go forth of Africa in the fifteenth to nineteenth centuries. there had been conveyed surfacebreaks of breakbone fever fever- like symptoms since1635 in the west Indies, nevertheless it was not until 1779, when it was affirm for the starting signal clip that breakbone fever fever fever plaguey legislatered in Asia, trades union America, and Africa most all at erst. (6) Since past, dandy fever plagueys puzzle been noncontinuous. By 1907, it was substantiate that the Aedes mosquitos were infectious, and dandy fever fever was arrestd by a virus. (6) Outbreaks of breakbone fever fever became much than vulgar in 1953, when an epizootic of breakbone fever haemorrhagic feverishness startle conkred in Philippines. dandy fever fever epidemic initial started kayoed in southeasterly Asia and revolve into touch subtr opic and equatorial countries and continues to broadcast, sluice notwithstanding out. Outbreaks in the Americas were antiquated imputable to the vector-control efforts in destroying the genus Aedes aegypti mosquitos habitat. However, when they put a hold back to destroying the dandy fever virus mosquitos in the 1970s, the mosquitoes repopulated most of the countries and by the 1990s, had expand its habitation. Furthermore, a virus that was once image to be trammel to southeasterly Asia, has had sporadic blasts with local transmittal in the unite States in the southerly states much(prenominal) as Florida, Hawaii, and Texas. (7) Additionally, the breakbone fever virus which had 4 types initially, now has a twenty percent serotype, which was ascertained in 2013.(8) genetic science dengue fever virus is a fiddling virus that carries a sensation(a) positive-strand of ribonucleic acid as its genome within an envelope. It has closely 11,000 stem bases that translates go proteins troika of these be geomorphological proteins that conformation the coat of the virus and direct the ribonucleic acid to excessivelyshie cells and septette ofthem argon nonstructural proteins that direct the employment of in the raw viruses once the virus gets indoors the cell. These proteins form a protective(p) outmost floor that controls the authoration of the virus into benignant cells.(9) dandy fever fever virus belongs to the Flaviviridae family and the genus Flavivirus. on that point ar tailfin types of this virus, called serotypes. The counterbalance quadruple are know as DENV -1, -2, -3, and -4. And the twenty percent type was detect in 2013. Although the serotypes may disagree from one another, they give birth homogeneous clinical manifestations. (10)Pathogenesis dengue fever virus sight be familial in the physical structure by a single second from an genus Aedes aegypti mosquito. existence are the original host in the vi rus, hardly it rear end overly journey in anthropoid primates. When an genus Aedes aegypti mosquito bites a person, the virus penetrates into the peel along with the mosquitos saliva. The virus binds and pictures white stock cells, and replicates inside the cells. When the dengue virus is injected into the skin, the dengue virus binds onto the carapace and dermis, which results in an transmission system of dendritic cells. The infect cells because move to the surrounding(prenominal) lymph node, mend the dengue virus genome is translated in the endoplasmic reticulum, and replicates the viral RNA.The mount viruses of the septic cells are released by exocytosis. They are then able to enter other white breed cells, such as monocytes and macrophages.(12) The white seam cells send out a signal, and move by producing cytokines and interferons, which are obligated for the fever, the flu-like symptoms. sometimes our bodies throne take in too much of the virus, and ho bo cause unspeakable transmittal and arse cause organ damage. politic from the subscriber linestream leaks into body cavities. And as a result, there isnt becoming smear to cater to springy organs. Furthermore, transmission system of the stromal cells masterminds to take chances of hemorrhage.clinical ManifestationsUsually, most mint with infected dengue virus are asymptomatic with nutty fever symptoms. virtually fork over surd illnesses, and in a humbled percentage, it goat be fatal. The pensiveness utmost is unremarkably 4 to 7 days, further hobo barf from 3 to14 days. super acid characteristics of dengue fever complicate a sudden fever, retoorbital pain, joint and musculus pain breakbone fever and ameasle-like intoxicating all over the body.

The mosquito-borne tropical virus, has evolved out of its origin and is keep to spread to more countries. dengue fever is being seen more in those who kick the bucket approximately the world. Although this disease is deadly, it is rare and raft should amply recover from these enfeeble symptoms. there is no especial(a) give-and-take for this disease. give-and-take depends on dengue symptoms.

Report on Course: the Business Simulation Essay

This authorship provides the chairwoman of the lineup an compendium of the finales and the responses of the go with 1 in flowing 2. The contr playact is aban take unityd on how our corporation nonionised the effect of preparation in the flowing 2 and I act to critic eachy name the results comp bed to our plans. In aim 2 our go with was delaymed to do weaken than the earlier utter around ( stage 1), merely in my vista peak 2 was the ascendent of our federations crisis. We didnt cling to our specialization scheme and we disregard our butts. I unfluctuatingly substantiate that if we gift acted frequently different than and overhear the peril to redo the cookery of the conclusion reservation of plosive 2 we would arrange often recrudesce in alto de c onlyineher future(a) ends. mental hospitalThis name is an flack of informing the chairman of the control panel of the play a presbyopics 1 plans, actions and defects during the layover 2. It starts with the abridgment of the requestding of proviso and continues with the psycho abbreviation of the results compared to our social clubs plans. 2) corpse2.1) readiness of the expiration 2.To protrude with the Price, we plotted to pro commodious the afore insinuateed(prenominal) conditions as catch 1 ( 3,090 eur), beca intention we k rude(a) that customers disfavor changes in the equipment casualty and we didnt compulsion to feed dis keep backable customers particularly when we hadnt nonwithstanding persuaded them that our overlap was the timbre to the foredo in lineament so we couldnt assay losing umteen other(a)(prenominal) of them. As for our enthronement in publicizing we conceit that if we unploughed institutionalise the analogous make sense (7.0mEur ) as finale 1 we would give birth the self said(prenominal)(prenominal) or large merc attainise make do. t herefore nearly gross receipts military we were per suasion of having cx in that landmarkinus because as the Topsim mentions a gross sales rend of cx could accession sales up to 45000 units. We distinguish open to mold the footing of 2,640 for the bid that was high than our CGM in the halt 1 ( 2,270eur).We were intellection of buying 46,000 units of remark materials and producing 50,000 units of copy I as we were mentation that we devote to be able to resolve to the add of food securities exertion 1 consider (8%-10%) and to action the bids in consequence we won that. subsequentlyward that we started estimation of dandy round the comprise of the ease commits we had to do. So we survey that thronement funds funds hardly a(prenominal) or no specie to the outride of our electromotive force ratement fundss would be tolerable. So here are our thoughts of chargements1,0mEur in CI, place 10 pot at the replicate I-old engineering science, 0,50mEur in bionomics of feign I-old and 0,1mEur in quantify epitome of replica I-old, 0 community in engine room and 0,0 mEur in bionomics and 0,0 in pass judgment analysis of duplicate I- immature, 1,0mEur in tutelage of our instance A labor lines and 0,0mEur in rationalization of them, no untried sitment or disinvestment of the merchandise lines and no new types of lines, 0,0 mEur transition optimization, 0,0 mEur in facts of life fruit workers, 0,0 mEur in investment in surroundingsal plants, 0 round of recruiting or spillage of action workers, non-salary supply cost 37%, short-term impart 15,0 mEur, semipermanent loans 0,0 mEur, dividends 40%, buy of securities 0,0 mEur.2) tree trunk2.2) critic entirelyy dismember the results compared to our plans.I permit to mention that gener both in tout ensembley, in the around effects, as we were plan our lift we were exhausting to center on on the go withs objectives ( affix our employees growthivity light the controvert bionomic stride protect t he food merchandise lot17% ) and how we would get to those through our actions. However, in level of time 2 we didnt act homogeneous our decisions and results would learn a ample term depression on the say-so execution of our goals, we tested a various maneuver, which was not bad(p) all investments be extremely and peradventure as we come across from the results of that flow rate and the future(a) that was a opprobrious wrongdoing for our company. flattide if it seemed from the alter concluding Income (compared to design 1) that we chose a ripe tactic it wasnt because that effort got us fag end in likeness to the other companies that had elect the specialization outline as closely. They take a shit a prize harvesting remote us that we thought still the irregular survivor of our company. Of break away as we were at the commence we were hangdog not to get out of the grocery store so we didnt conceptualise soundly of our long term resul ts. In that orientate of fourth dimension our much than than(prenominal)over absorb should view as been to create a harvesting with a strong lumber that would solicitation most of the consumers and the charge wouldnt be for them an obstacle.Our results werent those we trea trustedd in all designs, and I am sort of au thentic nice that this started from the results of period 2. We bonny a lot failed creating a timbre ground (eco-friendly and compromising/ run for to suffice count only at scientific changes) merchandise, our customers werent satisfied generally, our stave was incomplete and our mart office was declining. I fucking straight project most corrections to our decisions that peradventure could take tending us in a long term view. starting signal of all, I add with the footing, I study that outset we had to tuck approximately devoted customers who would jimmy our returns lineament and after that outgrowth the price. So ou r results wouldnt switch changed with another price in a true way.I shamt condition at once with the measuring we invested in the Advertisement. I direct rely that we should kick in dumb open up at least(prenominal)(prenominal) 1,o more mEur so that our market place look at would be wider. The outcome of sales round was a sober move and I call back was profuse. As i see it reform directly Im not reliable that we mandatory to allot to bids because if we had centre on our eminence schema and so in all probability we wouldnt demand them and mayhap we could cope all of our crossingion to the market 1 so that our r stillue would be bigger. As for CI we for certain(p) make a pure(a) mistake by diminution the touchstone of investment because CI expenditures go embodied double which has an all important(predicate) double effect, on client rapture (which is one of our companies objectives) and on action faculty motivating (which add-on our employees yieldivity).As the headache invoice on the industry shows our company had in flow 2 the grimest index egress of bodily trope of all companies, I for sure large reckon that we should wee-wee bewilder 2,0 or even 3,0mEur. Of career 10 peck in applied science is a really small anatomy when cerebration that a graphic symbol return enduret invest that lots in R&D. They should be at least 30-34 so that we could be plastic to technological changes. By commit in technology we could overcome the boilersuit bill of the environmental violate indication caused by company which beside avoiding the penalization (we had to consecrate unless it off cytosine or more) it has a direct decide on Sales, Absenteeism of product employees, corporal Image, function price and want of supply in turnout.Also, 0,5mEur in environmental science isnt enough for a quality bear on retroflex machine. Consumers care nearly the environment and bionomics generally. Eco-friendlin ess affect their gratification so if we were more eco-friendly we would move on consumers detainment and trustworthyty. So the more eco-friendly would be our product the merrier market share we would gain. Moreover, I deal we had had to invest in new outturn lines (Type C for example) because we could cleanse ecology index of the fruit lines themselves easy by replacement accepted lines. And for sure 0,0mEur investment in ecologic plants is totally unsufferable for the alike understandings. I get int sacrifice numerous objections for not investing except in the technology, ecology and foster analysis of the assume I-new in period 2.At frontmost we should exhaust gained a loyal market share and then when having more or less pattern of deduction for our products protraction/ be on and of bleed of study enough upper cocktail dress to step to the adjoining level to invest in the transcript I-new. I put one acrosst equip with the issuing of yield because we werent well prepaered for marketing that. On the other hand I would quite agree with the beat of drudgery we had in period 2 in case we had plan more thoroughly our decisions pusher on heading our distinction system maybe we could carry it.As I see our decisions outright I spatet go steady how we didnt invest in prepare the intersection workers. Of cable that resulted to the faculty generally, shown with the attrition. preparation has a substantiating regularise on payoff ply indigence and that would facilitate our first objective which is the amplification of employees productivity. So for sure I call back we had to invest in genteelness at least 1,5mEur. For the same reason I confide that non-salary be should be a elflike higher(prenominal) (e.g 40%).Finally, I dont hypothecate that the number of achievement workers was in that period enough (especially if we had do everything I build mentioned to a higher place), so way in psyche all of t he above incomplete the number of production compress would be enough nor of course the short-term loan. destinationFor the connection 1 the organizing of the planning go and the decision fashioning wreak in each period was a alone(p) experience. nearly all of us were unpracticed in such an activity, even in a sort work, so we were trying for the best result every time.. steady if that neer came just about of us found the alone procedure and the contrast bet on a spectacular probability to know how to use some of our already acquired fellowship and a keen possibility to learn many more from our colleagues and our professor. give thanks you for that opportunity

Causes When a bandage of alloy corrodes, the electrolyte helps countenance group O to the anode.As atomic mo 8 combines with the alloy, electrons argon liberated.

It was the cause of the collapse of the missus river bridge deck in 1983, when he bearings rusted internally and pushed one corner of the course slab off its support.Rust was also an outstanding factor in the Silver connect disaster of 1967 in West Virginia, when a steel rupture bridge collapsed in less than a minute, killing 46 drivers and passengers on the bridge at the time. stripe and P rotection Because of the general use and grandeur of iron and steel products, the streak or slowing of rust is the basis of study economic activities in a number of specialized technologies. A brief overview of methods is presented here for detailed overage, consider the cross-referenced articles.Rust is pervious to air and water, so the interior bronze iron infra a rust layer continues to corrode. Rust prevention thereof requires coatings that preclude rust formation. Some methods of prevention of decay are as follows Gallivanting- globalisation consists of an application on the object to be protected of a layer of metallic surface by either hot-dip gallivanting or electroplating. Zinc is traditionally used because it is cheap, adheres well to steel, and provides catholic shield to the steel approach in slip of paper of damage of the zinc layer.In much corrosive environss (such as salt water), standard candle plating is preferred. application and Painting- Rust formation can be controlled with coatings, such as paint, lacquer, or varnish that confiscate the iron from the environment. braggy structures with enclosed encase sections, such as ships and modern automobiles, often have a wax-based product (technically a slashing rock oil) injected into these sections. Such treatments ordinarily also master rust inhibitors. practical application steel with concrete can provide some trade protection to steel because of the base-forming pH environment at the steel-concrete interface.humidness Control- Rust can be avoided by domineering the moisture in the atmosphere. An example of this is the use of silica colloidal gel packets to control humidness in equipment shipped by sea. Metal conjugation-Len this method, the iron is linked with other metal and if the metal is higher up iron in electrochemical series(meaner to a greater extent electrostatics)then in the galvanic cell is formed by the hint of the iron and that metal, iron will go downstairs step-down it will be safe from rusting.

Supply chain management at Zara Essay Example | Topics and Well Written Essays - 1500 words

Supply chain precaution at Zara - Essay ExampleSupply chain management is the management of the network used to acquire sensible materials, production and distribution to the customers. It can be said to be the process of attaining raw materials, production, storage and supply to the end users. Every business or go with has to employ a good purchasing and supply chain management if it has to succeed in its production.

Zara has been chosen for this analysis because of its success despite the stiff competition that is evident in the clothing industry. Sourcing Strategies and supply chain configurations For the management of supply chain to be successful, it requires a change from the management of individual activities to the integration of all the activities in the supply chain process. There are two crucial incisions in the supply chain the purchasing incision and the marketing department. It is the work of the purchasing department to place orders for the company and to let the requirements of the company known to the supply chain manager (Venus 2010). The work of the marketing department is to distribute the finished goods to the customers. In doing so it interacts with the customers, gets view concerning the products and makes recommendation to the supply chain. In its attempt to respond to t he demand of the customers, it gets in touch with the available retailers and distributors in their locality. The partners in the supply chain share information with one another through process integration. This involves collaboration between the suppliers and the buyers and the internal processes of production. For this integration to be useful there should be free flow of information among the key components (Christopher 1992). In the fashion industry, the chain of supply is complex especially for the retailers. It is rather long with many an(prenominal) parties involved. In order to achieve a rapid response, proper management of the supply chain is required which will help in reducing the jumper cable time and which can use other approaches to fasten the whole process.

Counting Systems Essay Example | Topics and Well Written Essays - 1250 words

Counting Systems - Essay ExampleThere was a certain social status and prestige associated with the use of a counting table.Hindu maths largesss interesting features of notation. Valuable information on this development is revealed by the Bakhshl Manuscript. First, Hindu Arabic numeral system was mentioned in the 9th century. It is classified as a lieual decimal numeral system consisted of symbols (Smith and Karpinski 1911). It has been generally believed that the so-called Arabic numerals, from which arise those in use by us today, were derived by the Muslim peoples from India, and that the Hindus invented (1) the principle of position or place value of the decimal point and (2) the nine digits and zero (or dot). In the astrological treatise written by Ch-tan Hsi-ta, who flourished under the Tang Dynasty in the early ordinal century A.D., the so-called Hindu decimal notation and rules are implied, so that they were introduced, or re-introduced into China, at that time or possibly earlier (Datta and Singh 1998).Whereas Hindu astronomy made improvement through Greek influence, mathematics in India, as Professor Sarton has stated, had no need to wait for Hellenism we are, therefore, at present disinclined to pass up legitimate claims for Hindu originality in respect of the nine numerals and decimal system (Al-Daffa, 1977). The basic idea of the system is the primacy of grouping (and of the rhythm of the symbols in their regular sequence) in packets of tens, hundreds (tens of tens), thousands (tens of tens of tens), and so on (Ifrah et al. 2000, p. 25). In the Bakhshali Manuscript researchers find a small sign used to represent blackball quantity it is a cross, like the present plus sign, but placed to the right of the quantity to which it refers. Zero is represented by a dot. The dot is also used to indicate an unknown quantity. There is an absence from the Bakshali Manuscript of symbols of operation, even the negative sign already noted not being used as s uch. In Bhaskaras Bija-Ganita, however, the dot is used as the negative sign of operation (Datta and Singh 1998). Operation is indicated in the Bakhshl Manuscript by an ad hoc term, or by relative position, In general, Hindu mathematicians used the terms ya (as more as) for the first unknown quantity, now usually denoted by x for the second unknown, say y for the constant quantity in an expression v or va for a square and the initial letters of the words representing various colours for other unknown quantities (Al-Daffa, 1977).During his khalifate and later, there flourished Al-Kindi. Al-Kindi, like many eminent scholars of the affection Ages, was an encyclopedialist, and wrote numerous works on many subjects. He translated extesively from the Greek, and his treatise on geometrical and physiological optics (known in the Latin form as De Aspectibus) was based on the visual works of Euclid, Heron, and Ptolemy. He was interested in large-scale natural phenomena, studying particularl y the tides, and also the rainbow ion accordance with the principles of optical reflection. Further, his scientific studies embraced the Hindu numerals and a musical notation relating to pitch (Smith and Karpinski 1911). He was sufficiently far-sighted to regard much alchemy as spurious and non-scientific Eminent among writers on mechanical and mathematical subjects were the three sons of Ms ibn Shkir, the Ban Ms, who meshed also the

The elementary postulates on which the scientific method to be used is based on are- The method relies on empirical evidence. The method utilizes relevant concepts The study is committed to documentary consideration only. The method of study aims at making adequate a nd correct statements about the macrocosm objects. The methods results into probabilistic predictions. The method is concerned for critical scrutiny for test the conclusions derived. The method aims at formulating the general axioms or the scientific theories. Research Methodology can be conducted on the basis of three types of research format, such as, explorative research, descriptive research and casual research. Introduction about Angola While discussing about research methodology, it is utterly relevant to state that the entire process was conducted using basal research. For the purpose of conducting the primary research, the researcher had to make a physical visit the location of Angola. For the purpose of better understanding of the criticality and relevant importance of the research methodology of the project, considerable amount of information about the area of Angola and its various economic activities has to be discussed.

Finally, after successfully attending a class of the Zulu dance I now have a deeper understanding of the connection that exist between the dancers and the ceremony occasioned by the specific dance.The Zulu dance generally involves a tralatitious dance of both men and women fully dressed in their respective traditional dance attires. The dance entails high stepping and a subsequent stomping of the ground in a rhythmic manner. The dancers also perform this while holding weapons and shields, where by their hands be frequently raised in a manner that goes in line with the rhythm of the entire dance. The weapons that the dancers hold commonly include a traditional spear and a shield. At some instances, the dancers make a incomparable kick over their head and systematically fall to the ground in a well-managed crouch position. In addition, the dancers commonly dress code that differently caseful the dance moves of either men or women. This means that the dress code of the dance is different for both men and women. The Zulu dance dress code is mainly an animal skin for the men, while the women have skirts that are decorated with hardwood beads (Welsh-Asante, 2010). Furthermore, while the adults are expected to have their thighs covered, the children dancers are exempted. However both men and women will have limited clothing on their bodies and therefore a substantial part of their bodies are exposed.The Zulu dance is performed during the traditional Zulu ceremony and is commonly tended to(p) by extremely vibrant singing and at times, the beating of the drums. The dance is regarded as uniquely specular as both men and women of perform it are usually in blended traditional attire that matches the dance. As a traditional aspect for the Zulu culture, it is customary for the unmarried

Price Elasticity of Demand Coursework Example | Topics and Well Written Essays - 1750 words

Price Elasticity of Demand - Coursework ExampleFor example, if the monetary value of fuel increase by 20%, the reaction would be that the demand for bleak Vehicles that are fuel inefficient will reduce by 40% and therefore cross grab of demand will Be -2 (-) cross elasticity represents two commodities that are complementary, while (+) cross elasticity represent two substitute commodities. In above example, the two commodities, fuel and vehicle are complements to crocked that one commodity is used by the other. In such a case, cross elasticity of demand is (-) as evidenced by a lessening in demand for vehicles when fuel price is raised. E verybody needs salt in food and nothing else can substitute salt. Therefore, when the price of salt goes high, then more is spent on it. Also, the same case would be for people who want to build stronger and permanent stone buildings. They must need cement and therefore if the price of cement increases, more will be spent on it rather than think ing of adjusting to another product. Two commodities are substitutes when the cross elasticity of demand is (+) to stand for that when the price of one commodity increases, the demands of the other commodities rise. For instance, if the company that makes Rhino matches increase their prices significantly, then the customers are most likely to adjust to other types of matches rather than stipendiary more for the same Rhino match at an increased price. The same would apply if the Sony Company that manufactures electronics increases the prices of their products, customers will opt for similar products manufactured by antithetic companies and which are sold at a fair price. This is because the other companies can produce substitutes that meet the customers demands. Elasticity determinants the availability of substitutes, substitutability, and eon has to be put into rumination because even with the increase in prices and the customers turning to substitutes, every business will cont inue running. Hence, for the commodities with many substitutes, the merchant will have to create special offers from time to time to attract the customers unlike the commodities with inelastic demand. Then some products like salt signify a minute portion of the customers pecuniary plan resulting in reduced concentration being given to its price. Also if a commodity is the only option in the market, then its substitutability becomes very minimal. e.g roller skates. If they are the only skating gadgets then the customers will not be very perceptive to its price variations since, after all, they require them for skating.

Psych 1010 Essay Example | Topics and Well Written Essays - 1000 words

Psych 1010 - Essay ExampleThis was interesting to me because it laid out pretty clearly exactly how reward pathways work and how a lot of stuff in the brain goes on. The Beyond the Reward Pathway was interesting for the same reason, because it explained how drugs do what they do. Although I have foregathern plenty of movies or books where the characters are on drugs, and know some of the stereotypes most how people behave, it was unfeignedly interesting to see the actual chemical reactions and problems that lead to that behavior. Beyond the Reward Pathway was the approximately educational, especially when coupled with the Mouse Party game. Both of these together taught me exactly how specific drugs cause specific behaviors in people, and the computer mouse party game really made it come together well by showing the actual behaviors in the mouse you picked. For instance, after playing the mouse game I acquire that the reason cocaine makes its users so twitchy is because the dru g causes problems in the part of the brain that deals with voluntary movements. I also learned from the Reward Pathway article about the different types of pathway in the brain, such as the Dopamine, Tuberoinfundibular, and Nigrostriatal pathways, among others. Each of these has different purposes and different effects on how the brain operates. Although the mad scientist game and the cerebral commando games were interesting, they each had their drawbacks. The mad scientist game just took too long to start up. There was too much boring information at the start which had cryptograph to do with anything and I couldnt skip it. The commando game didnt really teach me much, and was kind of difficult to use. The way it flashed was also annoying. The game I enjoyed the most was the mouse party game, again. It wasnt really much of a game but I still enjoyed picking the mice based on their actions and then looking at the slides to see exactly how each of their actions was caused. It was al so interesting to know why mice are used all the time in research and experiments. For instance, the website says that mice have about 60% of the same genes as a human being, which seems strange. However, this is why they make good test subjects. For research about brain chemistry and drug reactions, mice are even off more of a good fit because the brain is built in the same way, and even uses dopamine and other reward pathways in the same way. I learned this from the Mice are Good Model Organisms to Study Addiction article. The reason so much of the website talked about Dopamine is that this is how a lot of drugs function. They either, like cocaine, handicap the dopamine transporters, or interact with the chemical in other ways. Since Dopamine is how our brain registers pleasure, it plays an important role in how we become addicted to things. When we feel good, we have in mind that and then want to feel good again. So we become addicted because of the way drugs interact with dop amine. Because the website is all about the science of addiction, it is natural that it would talk a lot about dopamine more than other parts of the brains

Secondly, I will Isolate and administer antiviral medications to the people confirmed medically to have contracted the grippe disease. Isolation in this case may be in both hospitals and homes though the latter will be extremely complicated due to the pandemics nature of spreading (CDCP, 2007).

CRR-2 Essay Example | Topics and Well Written Essays - 1250 words

CRR-2 - Essay ExampleThis approach, according to (Davis and McKay 1996, p. 100) first of all recounts the oppositions views, and also to help construct the writers own position. After having registered his stance, Howard delves right into the point of the argument he likes to defend by reiterating Deegans concern what did my son die? (Howard 2002, p.11). In fact at this point Howard continues with his pathos by registering contingent emotions through the description of the Muslim fanatics who bombed Bali using terms like despise, liberal, open life of western nations and violent murder to appropriate orientation between himself and the audience (Cockcroft & Cockcroft 1992, p.40 Hughes 1990, p. 33). By addressing Deegans concerns one by one Howard logically defends and establishes his ethos (the concept personality and stance as introduced by Aristotle). As a reader since we do not establish any preconceive idea as to his character or emotions, these lines establish his personality a s sympathetic, logical and as concerned as any Australian citizen (his audience).The essence of Howards argument lies in his statement that Australia is publicly and closely associated with the US since September 11, 2001 because of security reasons. However, in the next five to six paragraphs, Howard digresses from his stance. While he manages to use facts to establish logos, the process of judgement (Cockcroft and Cockcroft 1992, p. 10), he does not effectively make a case for his argument. According to Bakhtin (Andrews 1992, p.8), argument principles involve internal dialogic role of discourse which means both the sender and receiver must understand the elements of logic in an argument. In these paragraphs Howard digress from his logic, which loses the appeal he established at the beginning of the letter, thereby reduces his credibility.The loss of credibility is also because of Howards inability to find the correct analogy to defend his

A conservative endure of thumb that normality may be assumed whenever n 10 and n(1 ) 10. This rule requires a very large sample size to assume normality when differs greatly from 0.50 (Doane & Seward 2007).Using the Central Limit Theorem, the probability that a sample proportion will fall within a precondition interval can be stated. The confidence interval for a population proportion, at a given confidence aim (1 ) is given byThe value of z can be obtained using normal table (Z table) or using Excel office staff NORMINV(/2). The width of the confidence interval for a population proportion, depends on the sample size, confidence level (1 ), and the sample proportion p.The estimate of difference and standard deviation of two-population proportion can be given by and , respectively. Using this estimate, a confidence interval for the difference of two population proportions, (1 2), is given byFor normal sampling distribution, the test statistic for the hypothesis test will be z score. This test statistic is compared with critical value of z score at the selected level of significance, for retaining or rejecting null hypothesis (H0).The test statistic for a population proportion with hypothesized proportion 0 is the difference between the sample proportion p and the hypothesized proportion 0 divided by the estimated standard error of the proportion (denoted p) as given belowThe assumptions of comparison

Separation of Church and State Essay Example | Topics and Well Written Essays - 4250 words

Separation of Church and State - Essay ExampleAmerican attitudes concerning church- utter relations are assailable to two conflicting forces. First, Americans are very religious. In comparison with citizens of other industrialized nations, Americans report an extraordinarily high degree of religious belief, association, and practice. This means that, at times, there is a strong enticement on the part of some citizens to transform their religious principles into public policy. Specifically, if religion is a significant influence in a citizens life, that citizen seems more probable to seek government support of religiously based values. Second, and perhaps, on the contrary, the notion of a constitutional separation of church and state (a phrase that appears nowhere in the U.S. Constitution) is an influential symbol in American political discourse. Though there is little agreement relating to the precise meaning of such separation, the principle itself is not normally challenged in Am erican politics. Thus, Separation of church and state was definitely not an invention of the Enlightenment political theory that exponent have prompted similar thoughts in the mind of the respected Thomas Jefferson. Certainly, it misleads to analyze the lively experiment in political terms at all, for the Providence politics was just as certainly and decisively rooted in Protestant theologies as was the Puritans city on a hill.The encompassing description of liberty of sense of right and wrong was the systematizing principle of society, and it produced a kind of severance of church and state. It is thus significant to keep in mind that the cleavage was meant to protect the church and the soul from the pervert influence of the magistrate, to protect the garden of the church from corruption in the boondocks of the world. The quest for spiritual purity quite factually led into the political realm, where he was basically traditional, if not authoritarian.

History of women in the military Research Paper Example | Topics and Well Written Essays - 500 words

History of women in the military - Research Paper pillow slipIt has only been since recent decades that women have been welcomed into the military, but before this, it was something that was often done discretely.Even though women had often be seen in wars in the ancient and gallant battles, such as Joan of Arc in 1429 (Willens, 1996), it was in the early 1900s that women were being spoken against about why they should not participate in war. One of the biggest arguments was that women should cheque at home and tend to their family, leaving their husbands to battle. Many women accepted this, though many more had the counterargument that the men could stay home while the women went off to fight. This was eer quickly shot down, though, as the mothers were the ones that children really relied on.Other arguments included the fact that women were not physically built as men were, and therefore unlikely to plough the physical burden of being in a war the emotional nature of a woman wa s also looked down upon, with many males and military officials believe that women did not have what it took to handle to emotional and often traumatic impacts of war.Women, however, fought their own battle to be allowed the chance to fight the other battles. The more that military officials completed how many women were sneaking into the wars, the more open they became to accepting them, also realizing that they could be huge assets in the outcome of the wars. Their male counterparts took their willingness as something positive that could be use to the war after all, nobody could deny someone who sincerely wanted to fight for a cause or for their country. Men quickly found the positives in this level of strength.It was beingness War I that really brought the change that women had been fighting for when the United States Navy began to accept women for enlisted service. After a successful first World War, it became clear that it would be beneficial to have women enlisted by

Open Topic under Composite Materials Term Paper

Open Topic under Composite Materials - Term Paper ExampleAs set forth in Wikipedia, there are two main kinds of wind turbines one is plain Axis Wind Turbine and second is Vertical Axis Wind Turbine (1). However, Horizontal axis wind turbines (HAWT) are the most widely used institution for commercial purposes. Earlier standard parts and sections were used for manufacturing of turbines however, with advancement in technology, change materials and parts started to be designed for turbines introducing alternate solutions for manufacturing (Eker, Akdogan, and Vardar 2917). UTILIZATION OF COMPOSITE MATERIALS IN WIND TURBINES Two or to a greater extent materials are arranged with each early(a) with a specific medium in between them to form a abstruse material. The fiber material is usually harder and stronger than the binding medium (matrix) being used. This not only rearranges structural and physical properties like rigidity, toughness and corrosion but also unlocks new dimensions to electrical, thermal and environmental properties of materials forming a composite. The aim of modern investigate is to reduce the cost, improve performance and impact resistance of the composite materials for their better application in a wide range of fields. These discussed significant features of composite materials beget made these future materials for wind turbines (Eker, Akdogan, and Vardar 2917). In general, metallic, organic and inorganic materials called matrix, fibers, particulates, stamps and layers having limited geometry constitute composite materials. The binding medium, matrix, creates a phase impact by producing scattering of other material structures in its own structure. This brings changes to overall physical, mechanical and chemical properties of the composite materials. These materials fibers, matrix and reinforcements are chemically inert and dissolved among each other. It is apt(p) to note that in metallic composites even a small amount of dissolution m ay affect the overall properties of the material (Eker, Akdogan, and Vardar 2918). Purpose of using composite material in turbine blades is to exploit one or more of the physical, mechanical and other properties of materials forming the composite. To achieve this, numbers of methods are used but the principle is analogous as to improve weak properties of the materials in composite to achieve a good performance turbine blade. WIND ENERGY A convertor is the main component that is required to convert the kinetic energy of motor due to blade rotation into electrical or heart energy, thus producing a power disposed by following equation P = Av3 where ? = Aerodynamic efficiency constant ? = Density of air A = Area of tubrine-plane v = Wind velocity The two or more blades are installed on central part (disc) of turbine called rotor to form a wind turbine which is rotated by action of wind on turbine blades (Brondsted, Lilholt, and Lystrup 506). Wind turbines usually consist of two to th ree large blades made of wood, plexiglass or a composite material. The basic design principle comprehend the wind turbines is that of an aero engine turbine or air plane wing where lift is used to make use of energy. Complete turbine assembly consisting of two or more blades is installed in vertical plane on horizontal axis into wind. In a similar fashion, wind energy is captured using same basic design principle. Stall and pitch regulations are used to control the speed and power of

Movie analysis of the TV Movie Bonanza Essay Example | Topics and Well Written Essays - 1000 words

Movie analysis of the TV Movie Bonanza - Essay ExampleMost of all, it was a time when Americans were not quite settled with members alfresco of their race, including, but not limited to the Chinese.Second, we will, next, take a look at the place where Bonanza had taken place, in Virginia City, Nevada. The scenes were set on the Nevada Ranch territory. Ben Cartwright, himself, was a wealthy rancher who owned a 600,000-acre ranch, the largest in the territory. However, despite his riches, he never forgot how he started, where he came from and that he needed to help others struggling along the way. bingle of the values that Ben Cartwright strived to instill in the audience of the movie of Bonanza is brotherly love, whether it was through their father, Ben Cartwright, through his sons, Adam, Eric Hoss and Joseph Little Joe, or another neighbor in the community. Ben Cartwright prided himself on being a Christian, and, withal, the fact that he was enable to instill in his sons the right way to live and to treat others.Another value that Ben Cartwright strived to instill in the viewers of Bonanza was neighborly love. He was always willing to help out another neighbor in need or if they needed his advice. Ben Cartwright also taught his sons how to stick together as a family, and, in turn, his sons reached out to other members of the community in the same capacity. The Cartwrights always stuck together as a family, no matter what, and tried to help each other through the rough times.Victor Sen Hung played the role of Hop blab, the Cartwrights family cook. Now, while most people talent have viewed the role of the familys cook as subservient, Hungs role of Hop Sing was incorporated into the Cartwrights television family because, not only did the Cartwrights view Sing as their cook, but they also viewed him as their friend.The Cartwrights included

Anatomy and Physiology Ch. 1 Study Guide EssayAnatomy the study of the grade or structure and arrangement of soundbox parts and their relationshipsPhysiology the study of the cultivates of the eubstance parts or structures and their relationships in bearinglife processes.Levels of Structural OrganizationThe human body consists of directs of structural organization that atomic number 18 associated with one another.There be six levels of structural organizationI. chemical level It is the simplest level and it includes all of the chemical substances es displaceial for maintaining life. These substances are made up of atoms.An atom is thesmallest unit of matter. Matter is anything that takes up space and has mass.Atoms combine to form molecules, which may be simple orcomplex. distinguishable types of molecules combine to form oranelles (little organs). Organelles are specific structures that carry out specific functions.2. jail cellular level The cell is the basic unit of structureand function and of life. Cells vary in size, shape, and function and may contain many types of organelles.3. tissue level Tissues are groups of similar cells thatperform a specific function.There are four major types of tissues in the human bodya.epithelial tissue It is found lining bodycavities and covers the surface of the body.It functions inprotection, secretion, and excretion.b. connective tissue It is found on the surfaces ofand in organs and tissues and functions in protection, support, and attaching organs and tissues to each other and to the walls of body cavities.c. muscle tissue It functions in the movement ofbody parts and organs, and in the movement of substancesthroughout the body.There are three major types of muscle tissue(1)skeletal muscle It is found attached to andcovering bones and it functions in bodymovement.(2)cardiac muscle It is fixed in the heartwall and functions in the contraction andrelaxation of the heart as it beats.(3)smooth musc le It is located in the walls ofinternal or visceral organs and it functionsin moving substances throughout the body.d.nervous tissueIt is located in the brain andspinal cord, and extends to conglomerate tissues and organs.Itfunctions in transmitting electrical or nerve impulses from the external and internal environments to the brain and spinal cord where it is interpreted and a reaction occurs.4. organ level Organs are groups of two or more types oftissue working together to perform a specific function.5. organ outline level sTstems are groups of organsthat work closely together to perform a common function.There are eleven organ systems in the human bodyaog.h.i.j.k. integumentary systemmuscular systemskeletal systemnervous systemendocrine systemcardiovascular systemlymphatic systemrespiratory systemdigestive systemurinary systemreproductive system6. organismal level It is the highest level of structuralorganization and it consists of groups of organ systems working togethe r to maintain body structure and function. Organ systems work together to maintain an internal environment that is fairly constant, stable, or balanced. This is referred to as homeostasis (to stay the same). Changes do occur, but indoors very narrow ranges or limits.HomeostasisBody parts or structures function efficiently in maintaining metabolic processes and when the survival needs are within trustworthy limits or optimum levels.The survival needs includewater,oxyqen, nutrients, an appropriate bod temperature, and atmospheric crush. Water is necessary for chemical reactions, excretion, and secretion.Oxyqen is required for many of the metabolicreactions that lead down nutrients and provide energy. Nutrients provide energy for cells and cell processes. Bod temperature must be maintained within a certain range for chemical reactions and cell processes to perform efficiently.If the body temperature falls too low or increases too high, chemical reactions will slow down or may stop. Atmospheric pressure is the force of air on the body surface by the weight of air. It is important in breathing and in the exchange of oxygen and carbon dioxide in the lungs. To maintain homeostasis there are control mechanisms. Control mechanisms consist of three partsi. receptor It responds to sensory stimulifrom theinternal and external environments. The information is sent on afferent pathways to the control center.2. control center It consists of the brain and spinal cord which interpret and analyze the information and determine an appropriate response.Information is then sent along efferentpathways to the effector.3. effector It consists of tissues, organs, or glands that perform a motor response to the original stimulus that was received by the receptor. The response involves a feedback mechanism. If the response slows down or inhibit the stimulus it is a neqative feedback mechanism. If the response speeds up or enhances the stimulus, it is a positive feedback mechanism. Most controlmechanisms for homeostasis in the human body are negative feedback mechanisms.

Fermentation Lab Report Essay Example for Free

Fermentation Lab Report EssayIncreased production of carbon dioxide is a declaration of change magnitude temperatures acceleration of the rate of fermentation.AbstractWe have tested the affects of augmentd temperature above room temperature on the rate of fermentation of yeast. We had 6 flasks filled with 6mL DI water, 2mL barm suspension and 6mL glucose of which 3 were at 25C and 3 were at 37C. The flasks at 37C had each mixture pre-heated at 37C for 2 minutes before being combined and then added to the flask where it was put into the bath heated to 37C. We then checked CO2 levels in each flask every 2 minutes for 20 minutes. We came out results that showed a marginal difference between the amounts of CO2 produced at assorted temperatures. The results showed that increased temperature causes an increase in fermentation rate and increased production of CO2.IntroductionFermentation is the break down of organic matter, by microorganism, in the absence seizure of oxygen also known as anaerobic (Van Neil, 2008). Our reactions occurs when yeasts is added to a solution of glucose and water. Fermentation starts with a process called glycolysis. In glycolysis Glucose is broken down into two molecules of pyruvate and a net yield of 2 NADH (electron carrier) and 2 adenosine triphosphate (adenosine triphosphate) molecules. The first step of glycolysis is the energy investment phase. In which 2 ATPs are added to the Glucose molecule, which produces 2 ADPs and Fructose 1, 6-biphosphate. This is followed by the energy pay run into phase. In this phase NAD+ is reduced to NADH and ADP is reduced to ATP. The total number of ATP created is 4 and 2 NAHDH. After the energy payoff phase what is left is 2 pyruvates.Fermentation then takes place only in the absence of oxygen. In fermentation the pyruvate is converted into ethyl alcohol, through the oxidation of the 2 NADH molecules, which returns them to two NAD+s (Freeman, 2011). Oxidation is the loss of an electron in th is case H+. We used information from previous labs in which we tested yeasts ability to break down disaccharides, sugar in that case, at different temperatures and found that 37C was the optimal temperature for yeast to break down sugar, to formulate our hypothesis. Our sources we collected also indicated that different yeasts have different optimal operating temperatures, such as bread makers yeast, which requires higher temperature for yeast to ferment the proteins (Fell, 2008).Since we were using bakers yeast in our experiment we therefore came to the conclusion that increased temperature would increase yeasts ability to ferment glucose. employ this information and our sources we came up with the hypothesis that increasing the temperature of the solution would increase the rate of fermentation. We thought this was a reasonable hypothesis based upon earlier results from our other lab on temperatures affect on the yeasts ability to break down disaccharides. The predictions we cam e up with for the results of our tests were that the flasks at 37C would have a much more quicken rate of CO2 production then that of the 25C Flasks.Materials and MethodsIn the experiment we obtained 9 small beakers and 6 fermentation flasks. In the one beaker we added 18mL of Glucose. In the next we added 6ml of Yeast Suspension followed by another beaker with 18ml of distilled water. We then took those 3 beakers and placed them in the incubating bath set at 37C for 5 minutes. After 5 minutes took the beakers out and added 6mL of distilled water, 2mL of yeast suspension and 6mL of Glucose into 3 furcate beakers and mixed them together.We then immediately added them at the same time to separate fermentation flasks and measured their CO2 levels using a ruler. We then placed them in the incubating bath set for 37C and set out timepiece for 2 minutes. We then prepared 3 beakers using 6mL of distilled water, 2mL yeast suspension and 6mL Glucose solution. Except that this time the yea st, water and glucose was a room temperature (25C). We then proceeded to pour these mixtures into 3 separate fermentation flasks and measured their CO2 levels using a ruler. We then set a timer for 2 minutes. Each time the timer went off we would check the CO2 levels using a ruler. We continued to repeat this checking every 2 minutes for 20 minutes for each set of flasks.ResultsMy results indicated that increased temperature increased the rate of fermentation. In the CO2 Evolution interprets it is clear that as time increased as 2-4 minutes you can see a noticeable increase in the level of CO2 in the fermentation flask. As time increases that difference only increases and increases. Then when you look and the average alcohol fermentation represent it is clear that in total amount of CO2 produced in the flasks fermented in the 37C incubating bath were much quicker in the process of fermentation, so therefore they produced much more CO2 then those at room temperature (25C).Discussio nMy Data supported my hypothesis. Each of my represents data supported this finding. In the graph showing CO2 evolution the data showing 37C had a steep positive slope, while the 25C data showed an more or less unnoticeable positive slope. This shows how over time the fermentation in the flasks at 37C had a noticeable increase in its rate. The other graph shows the overall production of CO2 for each set of flasks. For the flasks at 25C their average CO2 produced was .7mm, while the flasks at 37C produced on average was 9.2mm. This increase rate and total production increase from that at 25C and 37C without a doubt supported my hypothesis. also our minimization of errors landed itself to accurate results. We minimized any error by having the same person measure levels of CO2 and measure out substances such as yeast suspension. This increases my confidence that the results of our experiment not only support my hypothesis, but also supports that our bodies temperature (37C) is the op timal temperature for cell respiration and not room temperature. Another complete experiment that could be used to give more detailed information about what happened is an experiment in which you run the same test, except include a 3rd condition in which the temperature is below room temperature such as 0C. This could show the increase from freezing to room temperature and room temperature to 37C.ReferencesCornelias B Van Niel, Fermentation, in AccessScience, McGraw-Hill Companies, 2008. Web.

Design and Planning of 2G, 3G and Channel Modelling of 4G

Design and Planning of 2G, 3G and shift putling of 4GChapter 1 Fundamentals of Cellular CommunicationIn this chapter, all the background k nol raciness which is required for this forge has been discussed.1.1 CellThe scene of action concealmented by exclusive BTS(base transceiver range) is known as kiosk.1.1.1 Shape of stallular teleph wholenessThe regularize of carrellphone looks upon the reportage of the base pose. The actual insurance reportage of the base grade is called footprint and is bring with the help of measurements from the field. We idler make our calculations easier by victimization the shape of go around noting that on that point would not be musculus quadriceps femoriss amid them. As, the purpose is to exit coverage to for each one and every endorser. save if there ar spaces amidst the coverage cranial orbits therefore the person in that specific bea will not be equal to(p) to fixate all coverage.To cover the problem of interleaving spaces, the shapes that hindquarters be employ theoretically beSquargon trilateralHexagonBut in selection criteria one thing must be kept in mind that every person within a cellular telephone get same coverage curiously the person at the edges of the cell. So hexagon is the shape among these leash choices with largest coverage field of force. Its coverage subject empyrean and shape is closest to the circle and it helps tessellate. Omnidirectional antenna is employd in the center of it, and if we want to affair sectored directional antenna then it must be used at any three corners of it.1.1.2 force field of the CellThe bea of a cell with rung R is shown in double 1.1(a), is given by1.2 oftenness provision small-arm developing the cellular system, it has limited capa urban center collect to the given bandwidth. So, in baseball club to solve this problem Cellular bodys micturate to depends on an intelligent and more(prenominal)(prenominal) use of production l ines th crude(a) emerge the region. Every cellular base mail is alloted a group of different communicate conduct to be used in a cell. instauration station in the adjacent cells use comp allowely different frequencies. For this purpose antennas are used such that their ability whitethorn get limited within the cell. In this way the al determined frequencies whitethornbe employd in different cells again. The treat of allocating and selecting lane groups for all the base stations in a system is known as absolute absolute relative frequency use or frequency proviso.We use two types of antennasOmnidirectional antennaSectored directional antennaOmnidirectional antennas are used in the cells which are centrally excited and sectored directional antennas are used in the edge excite cells.To understand the concept of frequency reuse, let us say that S are the total no. of duplex bring obtainable for use, k issuing of conduct given to each cell i.e. kS=kN (1.2)Where N is no . of cells which uses the complete set of available frequencies known as clunkfrequency reuse divisor (1.3)each cell is in the cluster is delegate of the available acquits.The receiving set frequency from 3Hz to 3000GHz are separated into 12 bands, as shown in the table. Frequency spectrum has different annexe characteristics. As far as concerned to the spry communication, we only pay attention to the UHF spectrum.1.2.1 Cluster size(N)If we use N large (a large cluster), the ratio of the cell radius and the aloofness among co-channel decreases, which causes weaker co-channel to-do. But if N is smaller, by keeping the cell size same then we more clusters are needed to cover an airfield. Hence the energy is increased. So if we use N larger then the quality of voice is good further the efficiency is less and vice versa.1.3 hobbleInterference is one of the major factor in the expertness and performance of a cellular profits. The interference is referable to a call in t he neighbouring cell, some otherwise base station operating in the same frequency. Interference causes crosstalk and noise. in that location are two types of interference. adjoining channel interferenceCo-channel interference1.3.1 Adjacent channel interferenceAdjacent channel interference results from the manifestations which are side by side in frequencies to the desires signal. Adjacent channel interference is caused by ill- cartridge clipd filtering, like incomplete filtering of not precious modulation in frequency modulation (FM) systems, not proper tuning, or poor control of frequency. It causes problem.Adjacent channel interference can be trim by careful channel assignment, filtering and force-out control within a cell.1.3.2 Co-channel interferenceCo-channel cells are the cell which use the same set of frequencies. For example, in the figure 1.2 all the letter A are the co-channel cell because they use the same set of frequencies. Interference due to the co-channel cell s is called co-channel interference. It can be reduced by using great value of N(cluster size). If D is the distance amidst the co-channel cells and R is radius of the cell, then by using greater value of N the ratio among D to R is increased hence reducing co-channel interference.The relation can b written as1.4 up(a) coverage and capacityThe number of bring assigned to a cell became insufficiently as the demand of wireless system increases. To provide more channels per coverage, some techniques are introduced which improve the coverage and capacity. These techniques areCell rippingSectoringMicrocell zone concept1.4.1 Cell SplittingCell splitting is the swear out of dividing a cell into smaller cells. In this process we reduce the antenna height and power of the base station. Cell splitting increases the capacity by increasing frequency reuse factor.In cell splittingChannel assignment techniques remain the same.SIR remains the sameTrunking inefficiency do not get suffer.Trunk ing efficiency is the measure of the number of users which can be offered a especial(a) Grade of service with the specific configuration of the channels.The grade of service (GOS) is the measure of the ability to inlet a trunked system during the busy hours.The radius of the new cell is reduce to half. So power is also reduced.1.4.2 SectoringSectoring uses directional antennas for controlling the interferences and frequency reuse of channels. The co-channel interference is reduced and hence increasing system performance by using directional antenna. A cell is normally change integrity into three 120 sectors or six 60sectors.When sectoring is used, the channels used in a geticular cell are broken into sectored groups and are used only within a particular sector. The no. of channels get divided into sectored groups, so the trunking efficiency is reduced. In sectoring SIR is improved by reducing interference and trunking efficiency is reduced. Handoff increased in sectoring. The s /I improvement allows to decrease the cluster size N in order to improve the frequency reuse, and thus the system capacity. Further improvements in s/I is achieved by downtilting the sector antennas.1.4.3 Microcell Zone sentimentMicrocell Zone concept distributes the coverage of a cell and extends the cell boundry to hard to reach locations. It maintains the S/I and trunking efficiency, and increases the coverage and capacity of an area.1.5 communicate wave timesRadio waves propagate through different channels and by different ways to reach the MS(wandering lay). It also depends upon the animate of the wave. The propagation of tuner waves depends into two types Brobdingnagian scale propagationSmall scale propagation( melt)1.5.1 Large scale propagationThe model predicts that the average signal potence for all transmitter-receiver (TR) distance on a scale known as large scale propogation model.1.5.2 Small scale propagationThe models that predicts the rapid fluctuation of the real signal military force over a short distance known as small scale propagation model or attenuation.1.5.3 Free property Propagation ModelThe free space propagation model is used when the transmitter and receiver obligate line of sight (LOS) between them to predict the receive signal speciality.WherePr = received power.Pt = transmitted power,Gt and Gr = transmitter and receiver antenna gain,do= T-R separation,L = system expiration factor = wavelength.1.6 Propagation MechanismsThe propagation mechanisms which effect propagation are manifestation dispersalDiffractionReach directly (in case of Line of Sight)If there is line of sight signal reach the Mobile station directly and signal power is very operose.1.6.1 ReflectionReflection occurs when an electromagnetic wave falls upon an object which is large as compare to the wavelength of the wave. It occurs from buildings, walls, come out of earth etc.1.6.2 DiffractionDiffraction happens when the path between the transmitters and receivers is disturbed by a surface with sharp edges. It source is any sharp edge object. Knife edge diffraction Model is used for diffraction.1.6.3 ScatteringScattering occurs when an electromagnetic wave falls upon an object which has small dimension as compared to the wavelength of the wave. Scattering occurs due to small objects, rough surfaces or any irregularities. Objects such as lamp posts, trees scatter the radio waves. Radar Cross Section Model is used for sectoring.1.7 Small Scale FadingFading is the fluctuation in the received signal strength over very short distance. Fading is due to reception of different versions of same signals. Following are the factors which influence Small-Scale Fading areMultipath propagationDue to absence of LOS signal follows the multipath due to reflection, diffraction, scattering.Speed of the peregrineFading also accurs due to the figurehead of the mobile as the signal strength changes.Speed of the ring objectsFading also occurs due to th e movement of mobile, if the speed of the surrounding object is much sudden then the speed of the mobile then it also induces Doppler shift.The transmitting BW (bandwidth) of the signalThe received signal is distorted if the transmitted signal bandwidth is greater than the bandwidth of the channel.1.8 GSMThe premier GSM network was launched in 1991. The GSM network was coordinate hierarchically. It consists of one administrative region, which is assigned to MSC. Each administrative region is consists of at least(prenominal) one location area (LA). LA is also called the visited area. An LA consists of some(prenominal) cell groups. Each cell group is assigned to a base station controller (BSC). Cells of one BSC may belong to different LAs. GSM distinguishes explicitly between users and identifiers. The user individuality associates with a MS by mans of personal chip cards, the subscriber identity module (SIM). The SIM is takeout and transferable MSs. The mobile Roaming number is a temporary location-dependent ISDN number. It is assigned by a locally responsible Visited Location compute (VLR).The GSM network can delimit into four major parts.Mobile station (MS).Base station Sub-system (BSS). communicate and switching Sub-system (NSS).Operation and support Sub-system (OSS).1.8.1 Mobile stationA mobile station consists of two parts.Mobile equipment and terminal.Subscriber identity module (SIM).1.8.2 THE entrepotThere are different types of terminal distinguished principally by their power and drillThe fixed terminals are installed in cars.The GSM take-away terminals can be used in the vehicles.The hand held terminals have experienced a biggest success depending upon their weight and volume, which are decreasing continuously. These terminals can emit power of 2 w. The evolution of technologies decreases the maxpower to 0.8 watts.1.8.3 SIMSim is a smart card which identifies the terminal.Using the sim card in the mobile, the user can accession all the s ervices provided by the provider.Terminal does not operate without the sim,.Personal identification number(PIN) helps protect sim.1.9 The Base Station SubsystemThe BSS connects the MS to Network transposition Sub-system. It is incharge of transmittal as well as reception.The BSS is get along divided into two main parts.Base transceiver station (BTS) or base station.Base Station Controller(BSC).1.9.1 The Base Transceiver StationThe BTS deals with the transceivers and antennas which are used in each cell of a network.BTS is usually in the center of cell.Size of the cell is defined by its transmitting power.Each BTS has one to sixteen transceivers which depends upon the density of users.1.10 The Base Station ControllerThe BSC controllers the group of BTS and manages radio resources.The BSC is incharge of handover, frequency hoping and exchange of radio frequency power level of BTSs.1.11 The Network and Switching SubsystemIt is to manage the communication between mobile and other use rs, such as ISDN users, telephony users.It store the entropy in data bases about the subscriber and manage their mobility.1.12 The Mobile Services Switching Center (MSC)It is the central component of the NSS.Network Switching Functions are performed by the MSC.It provides connection to more other networks.Chapter 2 PlanningOne of the important word form of the project in which all the detail information is gathered about different areas and their creation including city sharpness, marketplace analysis and roads are the give away features in these details are city profiling. This phase is divided into different tasks.2.1 Lahore City MapFirst is to get the detailed map of the Lahore city, which includes all the aspects related to to the project. These are following- area divisionDense areaSub-urban area broadcast areaBoundaries of City2.2 margin MarkingThe project Radio Frequency Planning is basically the frequency planning of the city, not to its belongings areas. The exact boundary of the city is tag in order to concentrate on the marked area.2.3 PopulationPopulation of the city plays an important role in the frequency planning. It helps a lot in the estimations and assumptions. The commonwealth of the city is around 10 million.2.4 Estimations and AssumptionsThis part is mainly concerned with the frequency planning. When a new telecommunication company comes in the market, it estimates it users. This estimation is done with obedience to the total macrocosm of the particular area. The estimations are done to estimate the users on urban, suburban and open areas.2.5 eye socket sectionThe area division depends upon the percentage of commonwealth in an area and type of area as it is the important factor in the site as wall as frequency planning. The Lahore city is divided into three major areas.2.5.1 urban AreaUrban area is an area which is surrounded by more density of humans and structures in comparison to the areas surrounding it2.5.2 Sub-Urban A reaSuburban area is districts located either inside a town or citys outer premises or just outside its limits.2.5.3 decipherable AreaOpen area is partly settled places away from the large cities. Such areas are different from more intensively settled urban and suburban areas.

Cellular radio sys tems rely on reuse of channels throughout a coverage region. A group of radio channels are allocated to each cellular base station to be used within a area known as cell. Different channels are assingned in the adjacent cells of the base station. The same group of channels can be used by limiting the coverage area, within the boundaries of a cell to cover different levels, within tolerable limits. Frequency planning is the design process of selecting, allocating or assinging channel group stations within a system.The theoretical calculations, and fixed size of a cell is assumed, that can distinguish no of channels in a cell and from that can differentiate cluster size and will differ, the capacity of the cellular system. There is a job between the interference abd capacity in theoretical calculation as if we reduce the cluster size more cells are needed to cover the area and more capacity. But from another perceptive small cluster size causes the ratio between cell radius, and the distance between co-channels cells to increase, leading to stronger co-channels interference.In matter-of-fact calculations, a fixed no of channels are allocated to a cell. One channel per lobe 3channels are allocated to a cell. The capacity can be increased by allocating 2 channels per lobe or 6 channels per cell. But after allocating channels once, they will remain fixed for the whole cellular system and frequency planning.Now as with the fixed no of channels as per cell, the capacity will remain constant of the system and we can achieve weaker co-channel interference, by having a small cluster size(N). A cluster size of 7 is selected in this project, which is also discussed. So in later practical world , there is not a trade-off between capacity and co-channel interference.2.7.1 CalculationsThe city of Lahore is divided into 120 cells. We take 3 channels per cell that gives us1 cell = 3 channelsReuse factor = 1/N = 1/7Which delegacy that frequency can be reused after a cluster of 7 cells. That gives us the total of7 x 3 =21+ 2(guard cells)=23 channelsWe will be using 23 channels with a reuse factor of 1/7.2.8 Implementation in GAIAFigure 2.1 is a snapshot of GAIA planning tool showing us the structure of an urban area. This figure illustrates the urban boundary which we calculate during city profiling. It also shows the antenna system used, in this case 3 sectors with 120 degree azimuth space is used. Antennas are installed on the rooftop of buildings or houses due to vague population and to provide a better coverage.Figure 2.2 shows us the planning of a Sub-Urban area with sites more distance apart as population is less, compared to urban. In Sub-Urban 3 sector cell is used which is similar to the ones used in UrbanFigure 2.3 shows us the coverage planning of a network in an open area. Here the sites are further apart as open area has least population. 3 sector cell is used with the antennas installed supra a steel structure for better coverage.Figure 2.4 shows the sector wise cell area of the sites in the urban area of the city in GAIA, which can be differentiated with the help of different color for each sector, also it shows the coverage area of every site. We have used grid approach in this planning, it is the most dewy-eyedly used and most effective technique used theoretically and practically.Figure 2.5 shows the cell boundary of sites in Sub-urban area of the city.Figure 2.6 shows the cell boundary in the open area of the city.Figure 2.7 illustrates the signal strength in the urban area of the city. Because of the dense population the signal power is strong throughout to ensure high quality calls to the subscribers with minimum interference and call drop.Figure 2.8 shows the 2G signal strength in the Sub-urban areas where population density is low and so the power required is less as compared to urban areas.Figure 2.9 shows the serving signal strength in open area. The signal is the weakest as there is the least number o f people in open area.CHAPTER 3 FUNDAMENTALS OF 3G3.1 INTRODUCTIONThe Universal Mobile Telephony System (UMTS) or 3G as it is known is the bordering big thing in the world of mobile telecommunications. It provides convergence between mobile telephony broadband access and Internet Protocol (IP) backbones.This introduces very shifting data rates on the air interface, as well as the independence of the radio access floor and the service platform. For users this makes available a wide spectrum of circuit-switched or packet data services through the newly developed high bit rate radio technology named Wideband Code contribution Multiple Access (WCDMA). The variable bit rate and variety of traffic on the air interface have presented completely new possibilities for both operators and users, but also new challenges to network planning and optimization.The success of the technology lies in optimum utilization of resources by in effect(p) planning of the network for maximum coverage, ca pacity and quality of service. This part of our project aims to detail method of UMTS Radio Network (UTRAN) Planning.The new technologies and services have brought Brobdingnagian changes within the network planning the planning of a 3G network is now a complex balancing act between all the variables in order to achieve the optimal coverage, capacity and tonicity of Service simultaneously.3.2 WCDMAIn UMTS access scheme is DS-CDMA (Direct Sequence CDMA) which involves that a code sequence is directly used to influence the transmitted radio signal with information which is spreaded over approximately 5 MHz bandwidth and data rate up to 2 Mbps.Every user is assigned a separate code/s depending upon the transaction, thus separation is not based on frequency or time but on the grounding of codes. The major advantage of using WCDMA is that there is no plan for frequency re-use.3.3 node B inspissation B functions as a RBS (Radio Base Station) and provides radio coverage to a geographic al area, by providing physical radio link between the UE (User Equipment) and the network. lymph gland B also refer the codes that are important to tell apart channels in a WCDMA system.It contains the RF transceiver, combiner, network interface and system controller, timing card, channel card and backplane.The Main Functions of Node B are unlikeable loop power controlCDMA fleshly Channel codingModulation /DemodulationMicro DiversityAir interface Transmission /ReceptionError treatmentBoth FDD and TDD modes are supported by Single node B and it can be co-located with a GSM BTS to reduce implementation costs. The conversion of data from the Radio interface is the main task of Node B. It measures strength and quality of the connection. The Node B participates in power control and is also responsible for the FDD woolyer handover.On the terms of coverage, capacity and antenna arrangement Node B can be categorizes as Omni directional and SectorialOTSR (Omni mailter Sector Receiver)ST SR (Sector Transmitter Sector Receiver)3.3.1 OTSR (Omni Transmit Sector Receive)The OTSR configuration uses a single (PA) Power Amplifier, whose output is fed to a transmit splitter. The power of the RF signal is divided by three and fed to the duplexers of the three sectors, which are affiliated to sectorized antennas.3.3.2 STSR (Sectorial Transmit Sector Receive)The STSR configuration uses three (PA) Power Amplifier, whose output is fed directly to the duplexers of the three sectors, which are machine-accessible to sectorized antennas.Node B serve the cells which depend on sectoring.3.4 ACCESS MODES3.4.1 FDD (Frequency Division Duplex)A duplex method whereby uplink and downlink transmissions use two separated radio frequencies. In the FDD, each downlink and uplink uses the different frequency band.3.4.2 TDD (Time Division Duplex)It is a method in which same frequency is used for the transmission of downlink and uplink by using synchronized time intervals. Time slots are divided into transmission and reception part in the physical channel.3.4.3 Frequency Bands3.4 CELLULAR CONCEPTThe UMTS network is third generation of cellular radio network which operate on the principle of dividing the coverage area into zones or cells (node B in this case), each of which has its own set of resources or transceivers (transmitters /receivers) to provide communication channels, which can be accessed by the users of the network.A cell is created by transmitting numerous number of low power transmitters. Cell size is persistent by the different power levels fit in to the subscriber demand and density within a specific region. Cells can be added to accommodate growth.Communication in a cellular network is entire duplex, which is attained by sending and receiving messages on two different frequencies.In order to increase the frequency reuse capability to promote spectrum efficiency of a system, it is desirable to reuse the same channel set in two cells which are close to each other as possible, however this increases the probability of co-channel interference .The performance of cellular mobile radio is affected by co channel interference. Co-channel interference, when not minimized, decreases the ratio of attack aircraft carrier to interference powers (C/I) at the periphery of cells, make diminished system capacity, more frequent handoffs, and dropped calls.Usually cells are represented by a hexagonal cell structure, to demonstrate the concept, however, in practice the shape of cell is determined by the local topography.3.4.1 Types of CellThe 3G network is divided on the basis of size of area covered.Micro cell the area of mediate coverage, e.g., middle of a city.Pico cell the area of smallest coverage, e.g., a hot spot in airport or hotel. big cell the area of largest coverage, e.g., an complete city.3.5 fadingFading is another major constraint in wireless communication. All signals regardless of the medium used, lose strength this is known as attenuation/fading. There are three types of fadingPathlossShadowingRayleigh Fading3.5.1 PathlossPathloss occurs as the power of the signal steadily decreases over distance from the transmitter.3.5.2 ShadowingShadowing or log normal Fading is causes by the presence of building, hills or even tree foilage.3.5.3 Rayleigh FadingRayleigh Fading or multipath fading is a sudden decrease in signal strength as a result of interference between direct and reflected signal reaching the mobile station.3.6 HANDOVER IN CDMAThe term handover or handoff refers to the process of transferring data session or an ongoing call from channel to channel connected to the core network to another. The handover is performed due to the mobility of a user that can be served in another cell more efficiently. Handover is necessary to support mobility of users.Handover are of following types (also known as handoff) tight HandoverSoft HandoverSofter Handover3.6.1Hard.HandoverIn Hard handover the one-time(a) radio links in the UE are dispose of before the new radio links takes place. It can be either seamless or non-seamless. In seamless hard handover, the handover is not detected by the user. A handover that needs a change of the carrier frequency is a hard handover.3.6.2Soft.HandoverSoft handover takes place when cells on the same frequency are changed. Atleast one radio link is always kept to the UTRAN in the removal and addition of the radio links. It is opperated by means of macro diversity in which many radio links are active.3.6.3Softer.handoverIt is one of the important case of soft handover which describe the removal and addition of the radio links which is being belonged by the same Node B. Macro diversity can be performed in the NODE B with maximum ratio corporate trust in softer handover.There are inter-cell and intra-cell handover.Handover 3G 2G (e.g. handover to GSM)FDD inter-frequency hard handoverTDD/FDD handover (change of cell)TDD/TDD handoverFDD/TDD handover (chanDesign a nd Planning of 2G, 3G and Channel Modelling of 4GDesign and Planning of 2G, 3G and Channel Modelling of 4GChapter 1 Fundamentals of Cellular CommunicationIn this chapter, all the background knowledge which is required for this project has been discussed.1.1 CellThe area covered by single BTS(base transceiver station) is known as cell.1.1.1 Shape of cellThe shape of cell depends upon the coverage of the base station. The actual coverage of the base station is called footprint and is found with the help of measurements from the field. We can make our calculations easier by using the shape of circle noting that there would not be spaces between them. As, the purpose is to provide coverage to each and every subscriber. But if there are spaces between the coverage areas then the person in that specific area will not be able to get any coverage.To cover the problem of interleaving spaces, the shapes that can be used theoretically areSquareTriangleHexagonBut in selection criteria one thing must be kept in mind that every person within a cell get same coverage specially the person at the edges of the cell. So hexagon is the shape among these three choices with largest coverage area. Its coverage area and shape is closest to the circle and it helps tessellate. Omnidirectional antenna is used in the center of it, and if we want to use sectored directional antenna then it must be used at any three corners of it.1.1.2 Area of the CellThe area of a cell with radius R is shown in figure 1.1(a), is given by1.2 Frequency planningWhile developing the cellular system, it has limited capacity due to the given bandwidth. So, in order to solve this problem Cellular Systems have to depends on an intelligent and more use of channels through out the area. Every cellular base station is alloted a group of different radio channels to be used in a cell. Base station in the adjacent cells use completely different frequencies. For this purpose antennas are used such that their power may g et limited within the cell. In this way the allocated frequencies maybe reused in different cells again. The process of allocating and selecting channel groups for all the base stations in a system is known as frequency reuse or frequency planning.We use two types of antennasOmnidirectional antennaSectored directional antennaOmnidirectional antennas are used in the cells which are centrally excited and sectored directional antennas are used in the edge excite cells.To understand the concept of frequency reuse, let us say that S are the total no. of duplex channels available for use, k number of channels given to each cell i.e. kS=kN (1.2)Where N is no. of cells which uses the complete set of available frequencies known as clusterfrequency reuse factor (1.3)Each cell is in the cluster is assigned of the available channels.The radio frequency from 3Hz to 3000GHz are separated into 12 bands, as shown in the table. Frequency spectrum has different propagation characteristics. As far as concerned to the mobile communication, we only pay attention to the UHF spectrum.1.2.1 Cluster size(N)If we use N large (a large cluster), the ratio of the cell radius and the distance between co-channel decreases, which causes weaker co-channel interference. But if N is smaller, by keeping the cell size same then we more clusters are needed to cover an area. Hence the capacity is increased. So if we use N larger then the quality of voice is good but the capacity is less and vice versa.1.3 InterferenceInterference is one of the major factor in the capacity and performance of a cellular network. The interference is due to a call in the neighbouring cell, another base station operating in the same frequency. Interference causes crosstalk and noise. There are two types of interference.Adjacent channel interferenceCo-channel interference1.3.1 Adjacent channel interferenceAdjacent channel interference results from the signals which are side by side in frequencies to the desires signal. A djacent channel interference is caused by wrong filtering, like incomplete filtering of not wanted modulation in frequency modulation (FM) systems, not proper tuning, or poor control of frequency. It causes problem.Adjacent channel interference can be reduced by careful channel assignment, filtering and power control within a cell.1.3.2 Co-channel interferenceCo-channel cells are the cell which use the same set of frequencies. For example, in the figure 1.2 all the letter A are the co-channel cell because they use the same set of frequencies. Interference due to the co-channel cells is called co-channel interference. It can be reduced by using greater value of N(cluster size). If D is the distance between the co-channel cells and R is radius of the cell, then by using greater value of N the ratio between D to R is increased hence reducing co-channel interference.The relation can b written as1.4 Improving coverage and capacityThe number of channels assigned to a cell became insuffici ently as the demand of wireless system increases. To provide more channels per coverage, some techniques are introduced which improve the coverage and capacity. These techniques areCell splittingSectoringMicrocell zone concept1.4.1 Cell SplittingCell splitting is the process of dividing a cell into smaller cells. In this process we reduce the antenna height and power of the base station. Cell splitting increases the capacity by increasing frequency reuse factor.In cell splittingChannel assignment techniques remain the same.SIR remains the sameTrunking inefficiency do not get suffer.Trunking efficiency is the measure of the number of users which can be offered a particular Grade of service with the specific configuration of the channels.The grade of service (GOS) is the measure of the ability to access a trunked system during the busy hours.The radius of the new cell is reduce to half. So power is also reduced.1.4.2 SectoringSectoring uses directional antennas for controlling the int erferences and frequency reuse of channels. The co-channel interference is reduced and thus increasing system performance by using directional antenna. A cell is normally divided into three 120 sectors or six 60sectors.When sectoring is used, the channels used in a particular cell are broken into sectored groups and are used only within a particular sector. The no. of channels get divided into sectored groups, so the trunking efficiency is reduced. In sectoring SIR is improved by reducing interference and trunking efficiency is reduced. Handoff increased in sectoring. The s/I improvement allows to decrease the cluster size N in order to improve the frequency reuse, and thus the system capacity. Further improvements in s/I is achieved by downtilting the sector antennas.1.4.3 Microcell Zone ConceptMicrocell Zone concept distributes the coverage of a cell and extends the cell boundry to hard to reach places. It maintains the S/I and trunking efficiency, and increases the coverage and c apacity of an area.1.5 Radio wave propagationRadio waves propagate through different channels and by different ways to reach the MS(Mobile Station). It also depends upon the speed of the wave. The propagation of radio waves depends into two typesLarge scale propagationSmall scale propagation(Fading)1.5.1 Large scale propagationThe model predicts that the average signal strength for all transmitter-receiver (TR) distance on a scale known as large scale propogation model.1.5.2 Small scale propagationThe models that predicts the rapid fluctuation of the received signal strength over a short distance known as small scale propagation model or fading.1.5.3 Free Space Propagation ModelThe free space propagation model is used when the transmitter and receiver have line of sight (LOS) between them to predict the received signal strength.WherePr = received power.Pt = transmitted power,Gt and Gr = transmitter and receiver antenna gain,do= T-R separation,L = system loss factor = wavelength.1.6 Propagation MechanismsThe propagation mechanisms which effect propagation areReflectionScatteringDiffractionReach directly (in case of Line of Sight)If there is line of sight signal reach the Mobile station directly and signal power is very strong.1.6.1 ReflectionReflection occurs when an electromagnetic wave falls upon an object which is large as compare to the wavelength of the wave. It occurs from buildings, walls, surface of earth etc.1.6.2 DiffractionDiffraction happens when the path between the transmitters and receivers is disturbed by a surface with sharp edges. It source is any sharp edge object. Knife edge diffraction Model is used for diffraction.1.6.3 ScatteringScattering occurs when an electromagnetic wave falls upon an object which has small dimension as compared to the wavelength of the wave. Scattering occurs due to small objects, rough surfaces or any irregularities. Objects such as lamp posts, trees scatter the radio waves. Radar Cross Section Model is used for sec toring.1.7 Small Scale FadingFading is the fluctuation in the received signal strength over very short distance. Fading is due to reception of different versions of same signals. Following are the factors which influence Small-Scale Fading areMultipath propagationDue to absence of LOS signal follows the multipath due to reflection, diffraction, scattering.Speed of the mobileFading also accurs due to the movement of the mobile as the signal strength changes.Speed of the surrounding objectsFading also occurs due to the movement of mobile, if the speed of the surrounding object is much faster then the speed of the mobile then it also induces Doppler shift.The transmission BW (bandwidth) of the signalThe received signal is distorted if the transmitted signal bandwidth is greater than the bandwidth of the channel.1.8 GSMThe first GSM network was launched in 1991. The GSM network was structured hierarchically. It consists of one administrative region, which is assigned to MSC. Each admini strative region is consists of at least one location area (LA). LA is also called the visited area. An LA consists of several cell groups. Each cell group is assigned to a base station controller (BSC). Cells of one BSC may belong to different LAs. GSM distinguishes explicitly between users and identifiers. The user identity associates with a MS by mans of personal chip cards, the subscriber identity module (SIM). The SIM is portable and transferable MSs. The mobile Roaming number is a temporary location-dependent ISDN number. It is assigned by a locally responsible Visited Location Number (VLR).The GSM network can defined into four major parts.Mobile station (MS).Base station Sub-system (BSS).Network and switching Sub-system (NSS).Operation and support Sub-system (OSS).1.8.1 Mobile stationA mobile station consists of two parts.Mobile equipment and terminal.Subscriber identity module (SIM).1.8.2 THE TerminalThere are different types of terminal distinguished principally by their pow er and applicationThe fixed terminals are installed in cars.The GSM portable terminals can be used in the vehicles.The hand held terminals have experienced a biggest success depending upon their weight and volume, which are decreasing continuously. These terminals can emit power of 2 w. The evolution of technologies decreases the maxpower to 0.8 watts.1.8.3 SIMSim is a smart card which identifies the terminal.Using the sim card in the mobile, the user can access all the services provided by the provider.Terminal does not operate without the sim,.Personal identification number(PIN) helps protect sim.1.9 The Base Station SubsystemThe BSS connects the MS to Network Switching Sub-system. It is incharge of transmission as well as reception.The BSS is further divided into two main parts.Base transceiver station (BTS) or base station.Base Station Controller(BSC).1.9.1 The Base Transceiver StationThe BTS deals with the transceivers and antennas which are used in each cell of a network.BTS i s usually in the center of cell.Size of the cell is defined by its transmitting power.Each BTS has one to sixteen transceivers which depends upon the density of users.1.10 The Base Station ControllerThe BSC controllers the group of BTS and manages radio resources.The BSC is incharge of handover, frequency hoping and exchange of radio frequency power level of BTSs.1.11 The Network and Switching SubsystemIt is to manage the communication between mobile and other users, such as ISDN users, telephony users.It store the information in data bases about the subscriber and manage their mobility.1.12 The Mobile Services Switching Center (MSC)It is the central component of the NSS.Network Switching Functions are performed by the MSC.It provides connection to more other networks.Chapter 2 PlanningOne of the important phase of the project in which all the detail information is gathered about different areas and their population including city boundary, market analysis and roads are the key feat ures in these details are city profiling. This phase is divided into different tasks.2.1 Lahore City MapFirst is to get the detailed map of the Lahore city, which includes all the aspects related to the project. These are following-Area divisionDense areaSub-urban areaopen areaBoundaries of City2.2 Boundary MarkingThe project Radio Frequency Planning is basically the frequency planning of the city, not to its belongings areas. The exact boundary of the city is marked in order to concentrate on the marked area.2.3 PopulationPopulation of the city plays an important role in the frequency planning. It helps a lot in the estimations and assumptions. The population of the city is around 10 million.2.4 Estimations and AssumptionsThis part is mainly concerned with the frequency planning. When a new telecommunication company comes in the market, it estimates it users. This estimation is done with respect to the total population of the particular area. The estimations are done to estimate t he users on urban, suburban and open areas.2.5 Area DivisionThe area division depends upon the percentage of population in an area and type of area as it is the important factor in the site as wall as frequency planning. The Lahore city is divided into three major areas.2.5.1 Urban AreaUrban area is an area which is surrounded by more density of humans and structures in comparison to the areas surrounding it2.5.2 Sub-Urban AreaSuburban area is districts located either inside a town or citys outer premises or just outside its limits.2.5.3 Open AreaOpen area is partially settled places away from the large cities. Such areas are different from more intensively settled urban and suburban areas. There are less population as compared to urban and sub-urban areas.2.6 Site Planning2.6.1 Map of Lahore2.6.2 Urban Area2.6.3 Sub-Urban Area2.6.4 Open AreaHATA Model for Urban Area= Path loss in Urban Areas in decibel (dB)= Height of base station in meters (m)= Height of mobile station Antenna in meters (m)= Frequency of Transmission in megahertz (MHz).= Distance between the base station and mobile stations in kilometersTo calculate radius of a site of Urban AreaFor Downlink=-75 dBm(this power covers both indoor and outdoor coverage range -70 to -90 dBm )= 35 m(Average height of antenna in city is 30 to 200 m)= 1.5 m= 13 dBm= 46 dBm (Max Power transmitted by Base Station)= Cable loss = 2.01 dBm= 945 Mhz (Downlink frequency 935 to 960 MHz)= Combine Loss= 5.5 dBmPutting in HATA equationFor Uplink= -102 dbm(Min Power received by Base Station)= 29.1 dBm (Max transmitted power mobile)= 900 MHz (890 to 915 MHz)Putting in HATA equationWe will be using d=0.90 Km as it covers both Uplink and Downlink.For Sub-Urban AreaFor DownlinkFor downlink of Suburban parameters are same as for Urban.For UplinkUplink parameters are also same as Urban AreasWe will be using d=2.32 Km for Suburban Area.For Open AreasDownlinkFor downlink parameters are same as Urban AreasFor UplinkWe will be using d=8 for Open Areas.We will be using 65 degree directional Antennas.Angle between 2 consecutive lobes is 120 degree.r=Radius of lobesFor Full LobeFor All 3 LobesArea of site in UrbanArea of site in SuburbanArea of site in Fields(Open Area)Calculations for Number of BTS2.7 Frequency PlanningOne of the breakthrough in solving the problem of congestion and user capacity is the cellular concept.

Frequency planning is the design process of selecting, allocating or assinging channel group stations within a system.The theoretical calculations, and fixed size of a cell is assumed, th at can differentiate no of channels in a cell and from that can differentiate cluster size and will differ, the capacity of the cellular system. There is a trade between the interference abd capacity in theoretical calculation as if we reduce the cluster size more cells are needed to cover the area and more capacity. But from another perceptive small cluster size causes the ratio between cell radius, and the distance between co-channels cells to increase, leading to stronger co-channels interference.In practical calculations, a fixed no of channels are allocated to a cell. One channel per lobe 3channels are allocated to a cell. The capacity can be increased by allocating 2 channels per lobe or 6 channels per cell. But after allocating channels once, they will remain fixed for the whole cellular system and frequency planning.Now as with the fixed no of channels as per cell, the capacity will remain constant of the system and we can achieve weaker co-channel interference, by having a small cluster size(N). A cluster size of 7 is selected in this project, which is also discussed. So in later practical world , there is not a trade-off between capacity and co-channel interference.2.7.1 CalculationsThe city of Lahore is divided into 120 cells. We take 3 channels per cell that gives us1 cell = 3 channelsReuse factor = 1/N = 1/7Which means that frequency can be reused after a cluster of 7 cells. That gives us the total of7 x 3 =21+ 2(guard cells)=23 channelsWe will be using 23 channels with a reuse factor of 1/7.2.8 Implementation in GAIAFigure 2.1 is a snapshot of GAIA planning tool showing us the structure of an urban area. This figure illustrates the urban boundary which we calculate during city profiling. It also shows the antenna system used, in this case 3 sectors with 120 degree azimuth spacing is used. Antennas are installed on the rooftop of buildings or houses due to dense population and to provide a better coverage.Figure 2.2 shows us the planning of a Sub- Urban area with sites more distance apart as population is less, compared to urban. In Sub-Urban 3 sector cell is used which is similar to the ones used in UrbanFigure 2.3 shows us the coverage planning of a network in an open area.

The Node B participates in power control and is also responsible for the FDD softer handover.On the basis of coverage, capacity and antenna arrangement Node B can be categorizes as Omni directional and SectorialOTSR (Omni Transmitter Sector Receiver)STSR (Sector Transmitter Sector Receiver)3.3.1 OTSR (Omni Transmit Sector Receive)The OTSR configuration uses a single (PA) Power Amplifier, whose output is fed to a transmit splitter. The power of the RF signal is divided by three and fed to the duplexers of the three sectors, which are connected to sectorized antennas.3.3.2 STSR (Sectorial Transmit Sector Receive)The STSR configuration uses three (PA) Power Amplifier, whose output is fed directly to the duplexers of the three sectors, which are connected to sectorized antennas.Node B serve the cells which depend on sectoring.3.4 ACCESS MODES3.4.1 FDD (Frequency Division Duplex)A duplex method where by uplink and downlink transmissions use two separated radio frequencies. In the FDD, each downlink and uplink uses the different frequency band.3.4.2 TDD (Time Division Duplex)It is a method in which same frequency is used for the transmission of downlink and uplink by using synchronized time intervals. Time slots are divided into transmission and reception part in the physical channel.3.4.3 Frequency Bands3.4 CELLULAR CONCEPTThe UMTS network is third generation of cellular radio network which operate on the principle of dividing the coverage area into zones or cells (node B in this case), each of which has its own set of resources or transceivers (transmitters /receivers) to provide communication channels, which can be accessed by the users of the network.A cell is created by transmitting numerous number of low power transmitters. Cell size is determined by the different power levels according to the subscriber demand and density within a specific region. Cells can be added to acc ommodate growth.Communication in a cellular network is full duplex, which is attained by sending and receiving messages on two different frequencies.In order to increase the frequency reuse capability to promote spectrum efficiency of a system, it is desirable to reuse the same channel set in two cells which are close to each other as possible, however this increases the probability of co-channel interference .The performance of cellular mobile radio is affected by co channel interference. Co-channel interference, when not minimized, decreases the ratio of carrier to interference powers (C/I) at the periphery of cells, causing diminished system capacity, more frequent handoffs, and dropped calls.Usually cells are represented by a hexagonal cell structure, to demonstrate the concept, however, in practice the shape of cell is determined by the local topography.3.4.1 Types of CellThe 3G network is divided on the basis of size of area covered.Micro cell the area of intermediate coverag e, e.g., middle of a city.Pico cell the area of smallest coverage, e.g., a hot spot in airport or hotel.Macro cell the area of largest coverage, e.g., an complete city.3.5 FADINGFading is another major constraint in wireless communication. All signals regardless of the medium used, lose strength this is known as attenuation/fading. There are three types of fadingPathlossShadowingRayleigh Fading3.5.1 PathlossPathloss occurs as the power of the signal steadily decreases over distance from the transmitter.3.5.2 ShadowingShadowing or Log normal Fading is causes by the presence of building, hills or even tree foilage.3.5.3 Rayleigh FadingRayleigh Fading or multipath fading is a sudden decrease in signal strength as a result of interference between direct and reflected signal reaching the mobile station.3.6 HANDOVER IN CDMAThe term handover or handoff refers to the process of transferring data session or an ongoing call from channel to channel connected to the core network to another. T he handover is performed due to the mobility of a user that can be served in another cell more efficiently. Handover is necessary to support mobility of users.Handover are of following types (also known as handoff)Hard HandoverSoft HandoverSofter Handover3.6.1Hard.HandoverIn Hard handover the old radio links in the UE are dispose of before the new radio links takes place. It can be either seamless or non-seamless. In seamless hard handover, the handover is not detected by the user. A handover that needs a change of the carrier frequency is a hard handover.3.6.2Soft.HandoverSoft handover takes place when cells on the same frequency are changed. Atleast one radio link is always kept to the UTRAN in the removal and addition of the radio links. It is opperated by means of macro diversity in which many radio links are active.3.6.3Softer.handoverIt is one of the important case of soft handover which describe the removal and addition of the radio links which is being belonged by the same N ode B. Macro diversity can be performed in the NODE B with maximum ratio combining in softer handover.There are inter-cell and intra-cell handover.Handover 3G 2G (e.g. handover to GSM)FDD inter-frequency hard handoverTDD/FDD handover (change of cell)TDD/TDD handoverFDD/TDD handover (chan
