spelling pronunciation - definition and examples

spelling pronunciation - definition and examples Definition The use of a pronunciation that is based on spelling rather than in accordance with a words conventional pronunciation, such as the increasingly common pronunciation of the once-silent letters t and d in often and Wednesday, respectively. Also called over-enunciation.D.W. Cummings notes that spelling pronunciations are more typical of American English than British English, perhaps because of the national predisposition among Americans to follow the written word more than the spoken (American English Spelling, 1988). The converse of spelling pronunciation is pronunciation spelling: the creation of a new spelling form on the basis of pronunciation. See Examples and Observations below. Also see: Allegro SpeechDivergent SpellingSlurvianWanna Construction Examples and Observations Words borrowed from French such as hour, honour, and honest came into English without an initial [h] as did hospital, habit, and heretic, but the latter have acquired an [h] from the spelling. The word herb is pronounced with an [h] and without one (the latter mainly in the US), and though hotel has an initial [h], one still sometimes hears an (h)otel. . . .The traditional pronunciation of forehead is forrid, but it is common nowadays to hear fore-head, particularly in the US. This is an example of reversing a sound change on the basis of spelling. . . .Many people believe that the spelling is a guide to the correct pronunciation and argue, for instance, that it is wrong to include an intrusive r in the idea of it or I saw him, because there is no r in the spelling.(Barry J. Blake, All About Language. Oxford University Press, 2008) Spelling Pronunciation and Language ChangeSpelling pronunciations are one symptom of the shift from the aural to the visual bias. . . . A sampling of spel ling pronunciations provided by [Fred] Householder includes the following, all of which have modern pronunciations that are closer to their spelling than were their older, traditional pronunciations: yesterday, Wednesday, diphtheria, diphthong, harass, kiln, victuals, conch, draught, certain, author, yes, housewife, gold, bomb, jaunt, laundry, sewer (1971, 252-53).Though underestimated, spelling pronunciation is an important and respectable factor in language change. . . . It seems likely that something like spelling pronunciation was part of the process that led to the leveling of dialect differences in late Middle and Early Modern English. Michael Samuels says that the evolution and spread of standard English in the 15th and 16th centuries was primarily through the agency of writing, not speech (1963, 87).(D.W. Cummings,  American English Spelling: An Informal Description. The Johns Hopkins University Press, 1988) Middle English Spellings and Contemporary PronunciationsSome words have not yet been accorded spelling-pronunciation, the words choler, debt, doubt, receipt, salmon, sceptre, victuals retaining the pronunciation better suggested by the Middle English spellings colere, dette, doute, receite, samon, ceptre, and vitailes. Words of a more literary flavour, e.g. victuals, are now occasionally heard with a spelling-pronunciation, and condemnation of such pronunciations as ignorant will probably not prevent their ultimate universal acceptance.(D. G. Scragg, A History of English Spelling. Manchester University Press, 1974) Pronunciation SpellingA pronunciation spelling is a spelling that more closely reflects the pronunciation of a given word than the words traditional spelling does. Over time the new spelling may become as acceptable as the original spelling, as is the case with the pronunciation spelling bosun for boatswain. Many writers use pronunciation spellings, as wanna for want to o r talkin for talking, to convey speech.(The American Heritage Guide to Contemporary Usage and Style. Houghton Mifflin, 2005)

Slavery and the Making of America Essay Example | Topics and Well Written Essays - 250 words - 1

Slavery and the Making of America - Essay Example Slave owners could sell their own children by proving they were illegitimate. Slave owners often slept with female slaves (Luminary_Aurora 2013). In the process, some of them conceived and depending on whether the owner was open about these relations, they could sell these children. Often considered an investment, slave owners could even intentionally impregnate their female slaves to place a sort of dividend. Slave owners considered the slave status something acquired from the mother only (Luminary_Aurora 2013). As a result, selling their children was not considered immoral or cruel. In effect, slave owners could either sell such children or keep them as their own slaves in hopes to make profits off of them.Frances Driggus went back to slavery after county Gaol found her guilty of theft in February 1699. Before this incident, Driggus allegedly stole meat from Charles Trelfo several years after being granted freedom (Luminary_Aurora 2013).

The Great Cat Massacre by Robert Darnton Essay Example | Topics and Well Written Essays - 500 words

The Great Cat Massacre by Robert Darnton - Essay Example The cat massacre served as a clever and afflictive attack on the print master and his wife. By killing the cats, the laborers get back at the master of the shop. The workers hated the cats because their masters love those animals and nurture them more than the workers. By first killing the mistress' beloved cat "la grise," the workers emblematically raped the bourgeoisie. It is a clear display of insult and threat as the workers assured her that no one would be capable of such a crime because they have too much respect for the house. Simultaneously, they caused the sovereign insult to their master-his wife being his most precious possession just as her cat was hers. The workers amused themselves with Lveill skillfully reenacting the horrible scene over and over during the following days. The mime was an atrocious and humiliating attack at the expense of the master's entire household. It provided entertainment for the men. It must be taken into account the unity of the workers against the masters. By executing the cats with such elaborate ceremony, they condemned master guilty-guilty of the unjust management of the shop towards apprentices. The cats were a representation of the masters, who were declared guilty of poor labor practices. In trying, confessing, and hanging a collection of half-dead cats, the workers meant to ridicule their master.

University of Wisconsin Admissions Essay Personal Statement

University of Wisconsin Admissions Essay - Personal Statement Example All skills that are necessary for one who ambitions to become a leader and not a follower in the future. These are skills and abilities that I did not realize I had until I became a member of the BBYO and found myself being asked to think about the kind of young leader that I could become. They called upon its members to strive towards becoming a national leader through the grassroots training that they offered. I dove into the challenge with excitement. I organized recruitment events in order to show the positive effect that our organization can have in their lives. All my hard work paid off as I was elected to the post of Regional Vice President for Communication (Northbrook chapter) , then programming (Overall, Illinois Chapter). Having been a ranking member of the BBYO for a number of years, I learned that life is not one person or race. It is about helping people reach their full potential in order to insure a steady flow of successful people in the future. We live in the land of opportunity. Unfortunately, not everyone knows how to get the best out of the possibilities presented to them. I know how to do that and I willing to share what I know with my fellow students. I plan to do this by working with the student government in mounting student mixers and career introduction seminars whenever it is possible. I am currently the youngest staff employee of Special Gifts, a Chicago based theater group that helps children with disabilities see that their handicap is not a hindrance but a gift that makes them special. I am truly saddened that I will be unable to continue working with them because theirs is a Chicago based group. But, I have plans of further spreading the good works of the group by founding a Madison community chapter. I hope, that once I am in a well placed position within the student population of UW, I will be able to find some students who would want to help further the cause of my theater

How Important Is Energy Sustainability Environmental Sciences Essay

How Important Is Energy Sustainability Environmental Sciences Essay Thesis statement: With non renewable resources of energy being consumed at a very rapid rate, sustainability of energy has become the need of the hour. In the current context of meeting the global energy demands nuclear energy meets every reasonable criterion for sustainability. The increase in the concerns about the harmful side-effects of global warming, coupled with a faster dwindling of the conventional sources of energy, have led to a renewed interest in nuclear energy. After the Cold War, nuclear energy development was largely forgotten for many years until this renewed desire among developed nations for the availability of alternative energy sources to meet their ever increasing energy demands. With the prices of oil and global warming concerns rising steadily, the clean-burning properties of nuclear power are becoming much more attractive. Nuclear energy is viewed as an ideal replacement for the non renewable sources of energy for the four following main reasons. Firstly Nuclear energy produces the most energy than any non-renewable resource. Secondly high reserves of uranium are found on earth which is the raw material for nuclear reactors. Thirdly there is no release of greenhouse gases such as carbon dioxide, methane, ozone, chlorofluorocarbons du ring a nuclear reaction. Finally the amount of waste produced is the least of any major energy production process. Although there are various risks involved when using nuclear energy, I will argue that nuclear energy is the best source of energy to replace oil and also I will argue that nuclear energy wastes are treatable, can be recycled and possess no threat to mankind.   Of the various advantages of nuclear energy, its efficiency is by far the most important. One of the major criterions that determine an efficient source of energy is the amount of energy it produces and how it impacts the environment. It is a basic energy fact that the fission of an atom of uranium produces 10 million times the energy from an atom of carbon than does coal. Nuclear energy extracts by far more energy from the natural resource Uranium than does the exploitation of oil or any other natural resource. In 1950s Dr. M. Hubbard, Geologist at Shell, said that US Oil would peak in 10 to 15 years. He was laughed at and in the 1970s we ran out of Oil. His statement was based on a Discovery Bell Curve which said oil production continues to go up even after the oil discoverys drop off and that the rate that we run out of oil can be measured on the lack of new discoveries. Heres a quote from NEIs website: Nuclear plants are the lowest-cost producer of baseload electricity. The avera ge production cost of 1.87 cents per kilowatt-hour includes the costs of operating and maintaining the plant, purchasing fuel and paying for the management of used fuel. These facts prove nuclear energy as the most efficient form of energy over its competitors, including oil, coal, wind, hydroelectric, and near-term solar power.   Many people are of the opinion that uranium is a rare metal, but its about as common as copper or tin and 40 times more common than silver. Uranium, the chief source of nuclear fuel, is vastly abundant, which makes this resource similar to other renewable resources. As per the NEAs (Nuclear Energy Agency) findings, uranium resources of total 5.5 million metric tons and an additional 10.5 million metric tons remain undiscovered-a roughly 230-year supply at todays consumption rate in total. Bernard Cohens, Professor of Physics at Pittsburgh University, 5 billion year estimate is based on extracting uranium from seawater, which the Japanese have already shown to work. Cohen calculated that we could take 16,000 tons per year of uranium from seawater, which would supply 25 times the worlds present electricity usage and twice the worlds present total energy consumption. He argued that given the geological cycles of erosion, subduction and uplift, the supply would last for 5 billion years w ith a withdrawal rate of 6,500 ton per year. His comments support the fact that uranium is a renewable resource of energy.   Among the many benefits of nuclear power, the main advantage of nuclear power over other methods is that it is a clean way to produce energy as it does not result in the emission of any of the poisonous gases like carbon dioxide, sulfur dioxide or nitrogen dioxide. With the pollution levels in the atmosphere greatly affecting the general climatic conditions, nuclear energy is definitely a preferable option when compared to burning of fossil fuels (Dujardin 2007). Production of nuclear energy doesnt contribute to emission of green house gases as it does in the case of fossil fuels. Also, going by the alarming rate at which the fossil fuels are burned, it is predicted that, the coal and oil deposits across the world are expected to deplete by end of this century. Uranium deposits, on the other hand are here to remain for a long time, and even if they get depleted, alternative sources in form of plutonium and thorium also exist.   Nuclear energy is also considered to be renewable depending on the type of reactor that is being used. A special type of reactor design called a breeder reactor can create or refine radioactive elements as a part of its functioning (Young, 1998). There are breeder designs that, once operating, can refine uranium, turning even natural uranium into fuel-grade uranium that can be used by other standard reactors. Some breeder designs create plutonium as a byproduct, which can be used for either power generation or in nuclear weapons. Currently, there are 442 reactors operating in the world, 130 of which are in the United States. Another 12 are being built in foreign countries. With the current technology, only 1% of the energy available in uranium is able to be captured by thermal reactors. This energy makes up between 11% and 18% of the total energy available in the world. Developing technologies that would allow us to capture more of this available energy is at least 15 years away, but with incentives, these advances could be a realistic part of our future. The potential is not the only part of the advantages of nuclear energy.   Nuclear energy has another advantage in that it is relatively inexpensive to produce when compared to conventional methods of energy production. Uranium is reasonably cheap to mine, and easy to transport to reactors around the globe, making nuclear energy. While the cost of producing other forms of energy has risen steadily over the last 26 years, the cost of producing nuclear energy has dropped, over the same period of time, with an average finished cost between 3 and 5 cents per kilowatt (Makhijani Saleska, 1999). The potential is not the only part of the advantages of nuclear energy. Regardless of the various definitions of renewable, nuclear power therefore meets every reasonable criterion for sustainability, which is the prime concern.   Both, the disadvantages and advantages of nuclear power plants have to be taken into consideration when determining whether this source of energy is efficient for development of power or not. While the critics of nuclear energy have been citing the various nuclear power plant disasters that have occurred in the past as one of the main reason for refraining from use of nuclear energy, its proponents are confident that it has the ability to sustain the energy requirements of the entire world, in a safe manner. Overall, however, I believe that the use of nuclear energy greatly outweighs any other sources of energy.  

An Internet for Everyone :: Internet Web Cyberspace Essays

An Internet for Everyone Web Sight by Arati Bechtel an article in the Camarillo Star, explains how the Internet claim that Everyone can use the internet is wrong in many ways. For people who are mentally or physically disabled, it is much more difficult to get the same access and effectiveness out of the internet as for someone who is completely healthy. The internet is about 99% visual and for someone who is visually impaired, it would be extremely difficult to use the internet. Arati Bechtel explains in her article about some of the research done on accessibility to the internet for the visually impaired and says that there is some new software for the blind that has been make with a better design to help them use the internet as apposed to the old way of using brail. An example of these programs is called Jaws Screen Reader, it is a program that takes the text and reads it out loud to the user. This allows a blind person to log on and listen to their email or listen to some information that they could pos sibly be looking for. But theses programs are not nearly enough and not nearly developed enough to be effectively used by the disabled. Bechtel states that more needs to be done for the internet to be used by everyone. Howard Rheingolds theory about the internet in his article The Heart of the WELL is that by logging on to the WELL, everyone can find there place for support or use it as a parenting community. Whichever way you choose to go, everyone will always find a place to feel comfortable in a community and find support from other people. (Rheingold 154) He describes how he and others in a community had an ongoing conversation with the father of a girl that had an illness, and with the support of the WELL, the woman was able to recover from her illness Figueroa 2 and come to a full recovery. He also described how a parent could have a question about the health of their infant child, and acquire the information quicker by logging on to the WELL and asking the users, then by call ing a doctor directly. (Rheingold 151) Another use of the WELL was to help each other on different parenting techniques assisting parents to become better mothers and fathers all around the world.

King Lear: A Tragedy Essay

In Shakespeare’s, â€Å"King Lear† the structure and elements of tragedy help develop the theme of greed throughout the play. In the first act of the play the reader is introduced to a proble, King Lear is getting old and when he passes away he doesn’t want his three daughters fighting for his kingdom. King Lear decided to play a game with them asking them â€Å"Tell me, my daughters, which of you loves us most, that we may place. Our largest bounty with the largest merit.† The King is playing a very selfish game with his daughters he wants them to tell him how much they love him. Goneril and Regan go along with his game because they both are power hungry and want the biggest part of the kingdom. They even lie to Lear and tell him that they love him more than anything, even more than their husbands. Both sisters are power hungry and selfish willing to put power before the truth. Unlike their youngest sister Cordelia, she refused to lie to her father and to ld him she loved him how any child should love their father. King Lear was angered by this and disowned her vanishing her from the kingdom. Lears actions showed how greedy he was with his daughters love and he wanted to make sure that they spoke his love for him out loud. An element of tragedy that appears in the play is peripeteia. This is shown when King Lear goes from being a powerful king to not being wanted by either of his daughters. Lear first arrived at Goneril place with his 100 man, although Goneril says†Ã¢â‚¬ ¦ Is most unseemly: hourly they break out In quarrels, bred by their unbounded riots..† Goneril doesn’t want Lear to have that many servants because she is afraid that she they will take over and over real her and she doesn’t’ want that because she wants to keep her power. Later King Lear goes to Regan’s palace but she doesn’t want him either. Both sisters have made up a plan to overrule Lear and make sure he doesn’t go back to ruling again. Goneril and Regan both are power hungry and are willing to pick power over family. Lear went from having all the love of his two daughters to being rejected by them in a series of tragic events. In the last act of the play the reader experiences catharsis, Goneril poisons Regan and later feels the guilt so she kills herself. Cornelia is hung and King Lear dies from the news, The deaths of the family show how throughout the book they every member of the Lear family was driven by greed, except for Cornelia. The audience sees what happened to a family full of greed and that was power driven. In the end no one wins the tragedy takes over. The last act (V) is the closing of the play it shows the results of the events that had occur.

Free Essays on Philosophical And Religous Influences Of The Constitution

Part One – The Legal Framework What were the philosophical and religious influences on American Constitutional Government? In framing the Constitution, the forefathers derived many of the foundations of constitutional government from philosophical and religious ideas. American Constitutional government was not perfect but a result of trial and error of almost two centuries of colonial existence. The origins of Constitutional Government stem from the Judeo Christian principles of covenant, justice, and inalienable rights. This idea was a reflection of the protestant influences and upbringings of the framers and that of the American people. The framers read extensively on the writings of Enlightenment thinkers such as Locke and Montesquieu, applying their ideas into the constitution. John Locke’s â€Å"Second Treatise† and his idea of the â€Å"social contract† was a major influence upon the construction of the constitution. According to Locke, the original state of nature was happy and characterized by reason and tolerance; all human beings were equal and free to pursue "life, hea lth, liberty, and possessions." Thus such rights could not be delegated or withheld from any individual in a state of society. The framers applied Locke’s social contract, which guaranteed a human’s inalienable rights to formation of the constitution. Also, Locke argued that revolution was not only a choice but in some cases an obligation when faced with tyranny. Baron Montesquieu’s, an influential French philosopher believed that in order to protect the liberty of the people, the government should be divided into three branches: the legislature, the executive and the judiciary. Montesquieu argued in his essay â€Å"Spirit of the Laws† that this was necessary to prevent the abuse of power, which he felt was the nature of humans.

Nash Equilibrium Theory

Nash Equilibrium Theory Introduction Nash equilibrium is a challenge that has acquired many increasing applications in both the internet and economics. It is evident from the internet that it is hard to count all the Nash equilibrium of a two player game. This is so even if the entry of the matrix is 0 or even 1.Advertising We will write a custom essay sample on Nash Equilibrium Theory specifically for you for only $16.05 $11/page Learn More Nevertheless, the complexity which is involved in finding the Nash equilibrium is open and has been actually opposed as one of the most significant wide open problems in the complexity theory today. There is a new polynomial reduction given in finding the Nash equilibrium in the general bi-matrix games in finding Nash equilibrium in the games where all the playoffs are either 1 or 0 (Kim, 2004). Once a given problem is shown intractable in the in complexity theory, the research for the same shifts towards the directions of polynomial algorithms for approximation or modest goals and the exponential bounds which are lower for the restricted algorithm classes. We however conclude that Nash algorithm is a concept of solution of a game that involves two or more players in it, where by assumption has been made that every player understands the strategies of the equilibrium for the players and that not even one player has a thing to gain by altering his own strategies unilaterally (Kim, 2000). Algorithm for the Nash equilibrium In calculating the Algorithm for Nash equilibrium, we give out a common algorithm for calculating the Nash equilibrium of the bi-matrix game within an exponential time. The calculation relies on the proposition that; given the existence of a Nash equilibrium with the supports S1 = Supp (x) and S2 = Supp (y), there will be a polynomial time of the algorithm in order to compute a Nash equilibrium with the definite supports stated. In the question, we will calculate the Nash equilibrium as follows: Let Si1 b e the ith row of S1, and Sj2 be the jth column of S2Advertising Looking for essay on math statistics?

The set of the constraints demands that the probabilities ai be non-negative and add up to one. They should also be 0 outside the required support with at least á µÅ¸ within the desired support (Freund, 2006). The following charts show the Nash Equilibrium tables. The steps I used in calculating the Nash equilibrium.Advertising We will write a custom essay sample on Nash Equilibrium Theory specifically for you for only $16.05 $11/page Learn More I examined the payoff matrix and determine what payoffs belong to whom I determined each player’s best response in all other actions of the other players, this process is done to all other players The Nash equilibrium hence exists where each player’s best response is similar to the other player’s best response For instance Step one Cooperate Non cooperate Cooperate 2000(B) 1500(A) 4000(B) 50(A) Non Cooperate 100(B) 2000(A) 101(B) 60(A) Step two Cooperate Non cooperate Cooperate 2000(B) 1500(A) 4000(B) 50(A) Non Cooperate 100(B) (2000) 101(B) (60) Step three Cooperate Non cooperate Cooperate 2000(B) 1500(A) 4000(B) 50(A) Non Cooperate 100(B) 2000(A) (101) 60(A) Proof of equilibrium The algorithm is simple and enumerates all the pairs (S1, S2) where by S1 is the sub set of the pure strategies of the row player while S2 is the pure strategies for the column player. For every pair, the equilibrium is used to find the Nash equilibrium in case one exists with the specified supports. In case no Nash equilibrium exists with the supports, the algorithm terminates within the polynomial time and either asserts that there is no solution existing or for one with a á µÅ¸ = 0. In the case latter case described, the solution to the problem will be a valid Nash equilibrium therefore the algorithm will find necessarily Nash equilibrium whenever it uses the initial algorithm on the support of the described Nash equilibrium. Hence, there exist at most the following in the solution: The 2m Ãâ€" 2n kind of pairs of the sets, therefore we get a total of (n + m) 0(1) 2(m + n) total time (Kim, 2000).Advertising Looking for essay on math statistics?

The proof is as follows: we can have the best of all correspondence for all other players with the relation from the set of the probability distributions over the profile of the opponent players to the set strategies as given in the supports, the profile of the mixed strategy of all the players except for player Si1. Analysis of negotiation algorithm Nash algorithm is a concept of solution of a game that involves two or more players in it, where by an assumption has been made that every player understands the strategies of the equilibrium for the players and that not even one player has a thing to gain by altering his own strategies unilaterally (Freund, 2006). Nash algorithm is a concept of solution of a game that involves two or more players in it, where by assumption has been made that every player understands the strategies of the equilibrium fo r the players and that not even one player has a thing to gain by altering his own strategies unilaterally. In calculating the Algorithm for Nash equilibrium, we give out a common algorithm for calculating the Nash equilibrium of the bi equation The path-order AR (AR(p)) Random Process is given by x(n) = −a(1)x(n − 1) − a(2)x(n − 2) − ãÆ' » ãÆ' » ãÆ' » − a(p)x(n − p) + w(n) (1) where by; w(n) is white noise having variance ÏÆ'w2 (k), k = 1, , p are the AR parameters. We assume that x(n) is real. The autocorrelation function of the AR process, rx(k), also satisfies the autoregressive property, this leads to the well-known Yule-Walker equations for the AR parameters rx(k)=- (k-i), k- 1 Suppose the measurements used to estimate the AR parameters can be modeled as ËÅ"x(n) = x(n) + v(n) where v(n) is white noise having variance  ¾2v, then the parameter estimates derived from the Yule-Walker equations will be biased since, rËÅ"x(k) = rx (k) +  ±(k) ¾2v where  ±(k) is the Dirac delta function. It has been shown that the biased AR parameters produce a â€Å"flatter† AR spectrum since the estimated poles of the AR process are biased toward the center of the unit circle [1]. A number of methods have been described for estimating the AR parameters using noisy measurements, some of these methods are surveyed in [1, 5] (Freund, 2006). The Noise-Compensated Yule-Walker (NCYW) equations are defined as (RËÅ"x −  ¸B) u = 0p+q (3), Where the dimensions of RËÅ"x,B, and u are (p + q) Ãâ€" (p + 1) , (p + q) Ãâ€" (p + 1), and (p + 1) Ãâ€" 1, respectively. The unknowns in (3) are u and  ¸, so clearly, equality holds when  ¸ =  ¾2v and u =  · 1 a(1) a(2) a(p)  ¸T. We observe that the first p equations are nonlinear in the AR parameters, u, and the measurement noise variance, The next q equations however are linear in u. In general there exist p distinct ( ¸, u) solving (3), the solution is taken to be that which corresponds to the minimum real value of  ¸ solving (3). A number of authors have observed that solving the p nonlinear equations, in addition to the q linear equations can improve the parameter estimates [2, 3, 4]. In [5], a matrix pencil method based on the Noise-Compensated Yule-Walker (NCYW) equations was presented which was found to out-perform several other methods for AR-in noise parameter estimation. None of these papers have established the minimum number of linear equations that are required for the solution of the NCYW equations to be the unique, correct solution. It is clear that q ≠¥ p linear equations are sufficient to insure that the solution is unique, in this case, all other ( ¸, u) solving (3) are complex. However, the minimum value of q needed to insure a unique solution has not been established. This is an important consideration because using a large value of q, which would guarantee a unique solution, also implies computing more high- order autocorrelation lag estimates which can reduce the solution accuracy since these tend to have a larger estimation variance. Hence one would like to choose the smallest value of q that still guarantees a unique solution (Friedman, 2001). One might expect that since there are a total of p + q equations in p + 1 unknowns, fewer then q = p linear equations are needed. In other words, if only one linear equation were used, q = 1, this would still give p + 1equations in p + 1 unknowns, hence a unique solution could still exist. In this correspondence, we show that this is not the case and q ≠¥ p is also a necessary condition for there to exist a unique solution (Friedman, 2001). Conclusion The coalition proof of the Nash equilibrium concept applies to specify non cooperative surroundings where by players can freely share and discuss their game strategies but cannot make any changes or even binding commitments. The concept emphasizes the self enforcing immunization to deviations . The best response in the game in Nash equilibrium is therefore necessary for self-enforceability. This is not sufficient generally when players can deviate jointly in a way that is beneficial mutually. The proof Nash equilibrium refines the concept via a stronger conception of the self-enforceability that gives room for the multilateral deviations (Freund, 2006). Nash algorithm is a concept of solution of a game that involves two or more players in it, where by assumption has been made that every player understands the strategies of the equilibrium for the players and that not even one player has a thing to gain by altering his own strategies unilaterally. To describe a standard ARMA equation we will use the example below which further breaks down the equations used in the autoregressive models. The calculation relies on the proposition that; given the existence of a Nash equilibrium with the supports S1 = Supp (x) and S2 = Supp (y), there will be a polynomial time of the algorith m in order to compute a Nash equilibrium with the definite supports stated (Freund, 2006). A number of authors have observed that solving the p nonlinear equations, in addition to the q linear equations can improve the parameter estimates [2, 3, 4]. In [5], a matrix pencil method based on the Noise-Compensated Yule-Walker (NCYW) equations was presented which was found to out-perform several other methods for AR-in noise parameter estimation. None of these papers have established the minimum number of linear equations that are required for the solution of the NCYW equations to be the unique, correct solution. It is clear that q ≠¥ p linear equations are sufficient to insure that the solution is unique, in this case, all other ( ¸, u) solving (3) are complex. In summary, Nash equilibrium is challenge that has acquired many increasing applications in both the internet and economics. It is evident from the internet that is hard to count all the Nash equilibrium of a two player ga me. This is so even if the entry of the matrix is 0 or even 1. Nevertheless, the complexity involved in finding the Nash equilibrium is open and has been actually opposed as one of the most significant wide open problems in the complexity theory today. There is a new polynomial reduction given in finding the Nash equilibrium in the general bi-matrix games in finding Nash equilibrium in the games where all the playoffs are either 1 or 0. In complexity theory, once a given problem is shown intractable, the research for the same shifts towards the directions of polynomial algorithms for approximation or modest goals, exponential bounds which are lower for the restricted algorithm classes (Friedman, 2001).

Deaf History and Culture - Essay Example At the age of nineteen months, Helen Keller was diagnosed as a case of â€Å"acute congestion of the stomach and the brain†. This short term attack of illness left her deaf and blind. Helen proved to be a quite an intelligent child. By the age of seven, she had invented sixty different signs to communicate with her family. Helen’s education career began when her mother took her to a specialist doctor for advice. Actually she was inspired by hearing about another child who was deaf but completed her education successfully. The doctor referred her to the local expert, Alexander Graham Bell. Bell was working for the deaf children at that time. Alexander Graham Bell told Helen’s parents about the institute where that child had got education. It was called the Perkins Institute for the Blind, located in South Boston. Helen was brought there. One of the former students of the school, named Anne Sullivan was designated as Helen’s teacher. She was blind herself an d had got education from the same institute. Anne proved to be a very hard working teacher. After a good effort of about three years, Helen learnt the names of many familiar things. The next step was to speak. Anne taught her to speak using the Tadoma method (touching the lips and throat of others as they speak). Helen continued her education starting from Perkins Institute, then Wright-Humason School for the Deaf, Horace Mann School for the Deaf, The Cambridge School for Young Ladies and finally, the Rad Cliffe College in 1900 becoming the first deaf and blind person to graduate from the college.

Geomorphology - Lab Report Example (5 pts) The critical angle for determining whether the boulder would move, or not is 45.840 degrees. At this point, the boulder would assume a stationery motion. The value is arrived by observing the point of intersection between the curves of shear and normal stress. 4. A local business informs you they have a 1 m-thick rock slab with a density of 1000 kg m-3 lying in their backyard that slopes at 25 degrees. Given normal weather conditions and unsaturated soils, will this rock slide and potentially destroy their business? Justify your answer in terms of angle, Driving and Resisting forces. (5 pts) At 25 degrees, the sheer force on the rock will be 984.807753 while the normal stress will be 173.6481777 (in the opposite direction). This means that the forces propelling the rock slab downwards are greater than the resisting forces. Assuming that the weather conditions remain at normal levels it is highly likely that the rock in question will inflict a considerable damage to the surrounding property.
