From the Paper
"Statistics is a branch of mathematics dealing with the collection, organization and analysis of numerical data the application of this information to make informed decisions in a variety of applications. Statistical results may be used to forecast business trends, define the extent of prevailing opinion throughout a given population, changes in availability of resources or assets, and provide quantifiable answers to questions in almost every type of business, social or political area. (Encarta) Professor Edwards of the Andover Theological Seminary defined statistics as "the ascertaining and bringing together of those facts which are fitted to illustrate the conditions and prospects of society.""

From the Paper
"The purpose of this research is to examine the nonfiction book How to Lie with Statistics by Darrell Huff. The plan of the research will be to set forth the main ideas of the book as a chapter-by-chapter summary of the important ideas, including examples of misleading uses of statistics of the type presented.
The Sample with the Built-In Bias. Statistical measurement begins with assembling a credible sample of respondents on which to base conclusions that can be generalized from the sample to the population. There are two factors to consider: whether the respondents are truly representative of what is being measured, and whether the respondents tell the truth when they are asked questions. Both features of a sample may contribute to bias in the reporting of information. Huff cites a survey in which voters in 1936 were asked over the phone predict election ..."

Abstract
This paper examines why it is necessary to learn algebra. It shows its everyday uses and importance. It uses some basic examples such as calculating the miles per gallon of a car, and solving a calendar riddle.
From the paper:
"Algebra is simply the branch of mathematics in which the operations and procedures of addition and multiplication are applied to variables rather than specific numbers. It is also probably the subject about which schoolchildren are most likely to ask the question: What good will this ever do me when I get out of school. This paper puts forth three different answers to that eternal question of what good will algebra do me?"

Abstract
This paper details how Galileo Galilei affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church.
From the Paper
"Galileo Galilei was a mathematician, an astronomer, and a physicist who made several significant contributions to modern scientific thought. During his life, he made many scientific discoveries, often in contradiction with the centuries-old ideas of the Greek philosopher Aristotle. These contradictions led to great conflict with the Catholic Church; however, he emerged as a symbol to others who oppose unyielding authority and champion scientific progress. As James Reston's biography Galileo makes clear, Galileo is a historical figure who affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church."

Abstract
The movie, "A Beautiful Mind", tells the story of Nobel Prize winner John Nash's struggle with schizophrenia. It follows his journey from the point where he is not even aware he has schizophrenia to the point where Nash and his wife find a way to manage his condition. The paper shows that the movie provides a lot of information and insight into the psychological condition of schizophrenia, including information on the symptoms, the treatment and cures, the life for the individual, and for the individual's family. The paper also explains that the movie is effective at demonstrating various concepts related to schizophrenia and provides a fascinating insight into the disease of schizophrenia.
From the Paper
"This leads to the other important point made from the film, which is that an individual can suffer from schizophrenia and still operate effectively. Nash's life is seen as he returns to the college to teach and continues completing his mathematics work, while still seeing the delusions. This life is clearly far from normal. But for Nash, it also seems the best option. At the end of the movie, it is shown that he has gained the respect of his co-workers. This suggests that with patience and understanding from others, individuals with schizophrenia can live effective lives, while managing their schizophrenia."

Abstract
This paper analyzes five of the most commonly used methods of risk management, establishes the differences, similarities and effectiveness among the given methods. and then draws conclusions regarding the effectiveness of each method.
From the Paper
"Project development, especially in the software related field, due to its complex nature, could often encounter many unanticipated problems, resulting in projects falling behind on deadlines, exceeding budgets and result in sub-standard products. Although these problems cannot be totally eliminated, they can however be controlled by applying Risk Management methods. This can help to deal with problems before they occur. Organizations who implement risk management procedures and techniques will have greater control over the overall management of the project. "

Abstract
This paper expounds the "Theory of Everything," starting with the pioneering theories of Newton's "Laws of Motion" and Einstein's "General Theory of Relativity," developing right through to the cutting-edge "string theory" research currently being conducted around the world today. It shows the importance of fields of study as seemingly diverse as calculus, differential geometry, electromagnetism, particle physics and quantum mechanics to the development of a "Theory of Everything."
From the Paper
"However, there is a fundamental discord between Einstein's "Theory of General Relativity" and quantum mechanics. Einstein saw the universe in four dimensions (the three dimensions of space plus time). The gravitational force that binds matter to the earth stems from this space-time continuum. Since quantum mechanic's subatomic particles only exist theoretically, they cannot be located in space-time and their motion can only be hypothesized. Thus, we have two theories that work individually but not together. There are also many unanswered questions. Relativity cannot tell us how the big bang created the universe or what black holes consist of. Similarly, quantum theory is not able to make order or sense of the assortment of miniscule matter it describes."

Abstract
This paper explains that, inevitably, bridges deteriorate over time at different rates: Timely maintenance activities, which are well-planned and carried out with minimal disruption to road users can present substantial savings in terms of both time and money for both bridge owners and road users. The author ponts out that, to tackle the complicated issues regarding bridge management, research activities in the UK as well as other countries in continental Europe concentrate largely on the bridge management process, with attention given to improving the use of limited finances to maximize the returns from the maintenance and repair of the bridge stock as well as reduce additional costs due to traffic delays and lane closures for these activities. The paper includes a critical review of other BMSs used worldwide, development of models to predict bridge condition over time, analysis of the various road user costs and using different optimizing techniques to best allocate finances and optimize bridge performance. 39 tables. 40 figures.

From the Paper
"It is proposed that the transition probabilities to be used are the Bridge Condition Index (BCI), which operates on a linear scale of 0 (worst) to 100 (best). The degree of severity of bridges is linearly distributed over this range (i.e. BCI of 50 to 51 is the same as 90 to 91), except that costs are expected not to have a linear distribution. This is a useful approach as the BCI (average) is interpreted as 'service potential' and is used as a performance indicator.
Using the example for multi span bridges earlier on, the transition probabilities for a three-state Markov chain model with limiting stage value of 3 is proposed. The probabilities are in accordance to the BCI values for the 'good' bridge arranged in order of descending magnitude (i.e. P(1) = 0.9845 and P(2) = 0.9246). For the purposes of comparison, the other two bridges ('medium' and 'bad') are also modelled and the three are plotted together."

Abstract
This paper expounds the "Theory of Everything," starting with the pioneering theories of Newton's "Laws of Motion" and Einstein's "General Theory of Relativity," developing right through to the cutting-edge "string theory" research currently being conducted around the world today. It shows the importance of fields of study as seemingly diverse as calculus, differential geometry, electromagnetism, particle physics and quantum mechanics to the development of a "Theory of Everything". It also demonstrates how those with access to this theory can use the knowledge as power for anything, such as understanding stock markets using the premise that the stock market moving up over time means that these are not random movements and therefore should be explainable.
From the Paper
"Stock markets exist over time and space (the geographical markets) that we are able to quantify and understand to a degree. Therefore, as with Einstein, we are fairly comfortable with the stock market in its familiar four dimensions. We have become accustomed to inflation; the rising of prices of goods rise over time and this is obviously a major reason for at least part of the upward rise of share prices. However, what happens when we explore the smaller dimensions " like the six unknown dimensions string theorists grapple with" Like the string theorists who know that subatomic matter exists but can't explain or predict its behavior, we often know what influences the stock market but are usually unable to predict it."

Abstract
A router is used to manage network traffic and to find the best route for packets to be sent. This paper discusses the algorithms available in order to find the best route to destination for these packets in the network environment. The two main algorithms are "Global routing algorithms" and "Decentralized routing algorithms". The paper evaluates in detail these two methodologies together with their bottlenecks and illustrates examples with diagrams, graphs, tables and code.
From the Paper
"In this step, routers should choose the best route for packets to every node. They do it by using an algorithm such as "Dijkstra Shortest Path Algorithm". In this algorithm, router, based on information that has been collected from other routers, build a graph of network. This graph shows the location of routers in network and their links. Also every link will be labeled with a number that is called weight of link and is also known as cost of link. This number is a function of delay time, average traffic and sometimes simply, it is the number of hops between nodes. For example if there were two links between a node to destination, the router chooses the link with the least weight."
