Bad Engineering in Science Fiction, 2004.
This paper discusses that four works of science fiction stand out for their use of bad engineering: Jules Verne?s ?From the Earth to the Moon? (1865); Karel Capek?s ?R.U.R?(1921); Fritz Lang?s ?Metropolis? (1926); and Maurice Elvey?s ?Transatlantic Tunnel

Abstract
This paper discusses that some of the devices and instruments featured in many popular science fiction novels and films are, in essence, conceived through bad engineering, meaning that these devices and instruments are neither practical nor possible according to present scientific knowledge. The author points out that Verne?s ?rocket to the moon? stands as the ultimate example of bad engineering, even when one takes into consideration that Verne was using his imagination as a means of conveying his ideas to the reading public, who, at the time of the novel?s publication, were obviously quite ignorant of science. The paper relates that Capek?s plot in ?R.U.R? is the seminal robot motif that has influenced every science fiction film, but the vision of creating a race of robots that take over the roles usually assigned to human beings in the context of work and labor was far-fetched for its time and is still so even in the 21st century.
From the Paper
"Michel Ardan then suggests that the spaceship launching will be powered by a formidable quantity of guncotton, and that the occupants of this spaceship will be protected from the shock of the launch by a layer of water filling the space between the vehicle?s double walls. There will also be thick glass portholes for observation, sealed during the liftoff and then opened by screws controlled from the inside of the vehicle. The air supply will be renewed by oxygen obtained by heating potassium chlorate, a powerful oxidizing agent. The flight, of course, will be monitored from the ground by a powerful Rocky Mountain telescope operated by the Cambridge observatory."

Abstract
This paper first describes what it is that buyers find so attractive in sports cars and then talks about what a buyer must consider when purchasing a sports car. The paper then goes on to explain that the superior engineering, design, reliability, and innovation of German sports cars makes them superior to Italian sports cars.
From the Paper
"Since the invention of the automobile, cars have taken an important role in our society. Once they were available only to the wealthy few that could afford them as a luxury in life. However, today cars have become a necessity for everyone. Everyone needs to commute to work, get to school, or go to the store; roads are filled curb to curb with traffic and cars of all sorts. However, that social status experienced by those wealthy enough to afford an early automobile can still be felt today by owning a sports car. ?Sports cars are for the individual who relishes a thrilling drive and a bolder visual statement with a hint of exclusivity. All style AND substance.... Power and speed, looks to die for and a throaty roar ? once you have driven a sports car then you never want to drive anything else.? (Sports Cars...) Like the change from riding a horse to driving a car, the difference between a standard family car and a speed-filled sports vehicle can be the boost to make life exciting again. Purchasing a sports car is a fun and exciting event, but one must remember that it is a very serious investment to make. Car lovers must consider many things when deciding upon a sports car, many things that do not necessarily go into the purchasing of a mini van for the kids."

The paper then goes on to outline and explain additional processes and engineering considerations concerning the removal of hydrogen sulfide and includes some cost estimates and comparisons of the processes.
Properties of H2S and CO2
Vapor / Liquid Properties of Pure Compounds
Vapor / Liquid Phase Behavior
Acid Gas Compression and Dehydration
Metallurgy
Acid Gas Dehydration
Acid Gas Injection Facilities
Cost Comparisons with Small Scale Sulfur Recovery Options
Operating Costs
From the Paper
"Sour natural gas contains hydrogen sulfide (H2S), which has to be removed to meet specifications for sales gas. Sour natural gas also contains carbon dioxide (CO2). The removal of CO2 and H2S, usually called acid gases, from sour natural gas is generally accomplished by means of a regenerative solvent. There are several amine solvents used for this purpose. Upon regeneration of the solvent, the acid gases are liberated, and are usually sent to a modified Claus plant, where the H2S is converted to elemental sulfur (Canjar & Manning 1967). The acid gas stream to the modified Claus plant consists of H2S, CO2, water vapor and minor amounts of hydrocarbon gas."

Abstract
This paper explains that graphs allow for a simplification of the real world, doing away with extraneous details without sacrificing any information necessary for the task. The author points out that graph theory is the best tool to use to solve the problem of road conversion because it is the most parsimonious. The assumptions made by graph theory more closely than any other model or theory match the real-world conditions. The paper states that, in converting roads, the effect in the real world will be a disruption of what had been the shortest paths between different points, and urban planners will include some consideration of shortest path issues. Tables and figures.
Table of Contents
Introduction
Graph Theory as the Basis for Conversion of Two-Way Roads
Undirected Graphs to Digraphs
Reachability Problem
Shortest Path Problem
Importance of Simulation
Comment on Validity of Data
Conclusion
From the Paper
"The specific shortest path method that is most useful in this particular type of problem is Pallottino?s graph growth algorithm with two queues. It must be emphasized that the determination of the shortest path algorithms is perhaps the most important component of any network analysis. It is also quite often the first step in any network analysis as the determination of the shortest path is often needed as a key datum in making later choices."

Abstract
This paper introduces the book, "Invention by Design" by Henry Petroski, published in Cambridge, MA, by the Harvard University Press in 1996. Specifically, it discusses what in the book is relevant to the mechanical engineering program, the author's main points, and whether these points are valid or invalid. It looks at how Henry Petroski's book takes engineering to a level that just about anyone can understand and makes it interesting even to the layperson. This book is not only an excellent introduction to the many facets of engineering; it is also a fascinating look into engineering by example, from the simple paper clip to the complicated Boeing 777 aircraft. It also shows how it is a fascinating look into what makes good engineering and what engineers actually do.
From the Paper
"Another critical issue in the book is how the case studies are presented. Each study begins with a bit of history, and then moves into the critical issues involved in the design and engineering of the object, such as the sewers of Paris as a precursor to the evolution of water quality engineering. Had the case studies taken a different approach, the book might not have met its goal of "making sense of many of the interrelated aspects of engineering," but because of these critical inclusions, the book not only meets, but exceeds its goals. It is clear that engineering is a vital force in the modern world, and that just about every action the engineer attempts can be critical in some form or another."

Abstract
This research paper investigates the affects of using capacitors to manage the disruptive harmful effects of VSDs to the power supply flow and evaluates factors that affect the cost?benefit ratio of these devices.
From the Paper
"Electrical equipment generically termed ?non-linear load?, such as variable speed drives (VSDs), uninterruptible power supplies (UPSs), computer power supplies, etc. have a detrimental effect on the quality of the supply to which they are connected. When determining power quality and taking any appropriate measures, it is common practice to monitor the point of common coupling (PCC) and this is often accepted as the point at which power comes into an establishment, i.e. the point of metering."

Abstract
This paper begins with a description of an article about volume translation technique and how it is widely used in in the field of chemical engineering. The paper explains the intent of the authors of the article, their findings, and the conclusion of the article. The paper then critiques the article and points out both its positive and negative aspects.
From the Paper
"The authors of the article are interested in studying various ways of developing equations of state, and they demonstrate that both theoretical and empirical approaches to equations of state can show them nonphysical behavior. They consider this information significant, but are also quick to point out that there is more to their research than just this bit of information. They are also interested in a clear and comprehensive understanding of the reasons for this. They believe that finding these reasons will help them and others to develop reliable equations, and that these equations can be based on both theoretical and empirical methods. Being able to do this would go a long way toward helping researchers who are working with information involving the development of equations of state."

Conclusion
From the Paper
"Another excellent technological invention from the past was the invention of the wheelchair. The wheelchair allows mobility. In the same way the aging process reduces the ability to see, it often reduces the ability to be mobile. Whether it is arthritis, a broken bone, or other physical problems, causing the inability to get around, a wheelchair can assist. Using a wheelchair allowed those who would otherwise have been bed bound to continue their lives. Past wheelchairs were large and bulky so the elderly who used them still had restrictions about where they could go."

Megalopolis, 2002.
An essay which describes the area in North America known as Megalopolis.
1,729 words (approx. 6.9 pages), 11 sources, MLA, $ 55.95
»
Click here to show/hide summary
Abstract
This paper describes the geographic region of Megalopolis (urban area in Northern America) and its sub-region of Nantucket (off Cape Cod). It also deals with the history of Nantucket and the causes that led to the formation of the megalopolis in northeastern USA. Megalopolis comes from the Greek words for ?very large? (Mega) and city (polis). The concept of Megalopolis lies in the fact that cities are not viewed as individual units but as regions that spread out from the city nucleus.
From the Paper
"Modern cities were formed as a result of the establishment of large-scale industries during the Industrial Revolution. Many people migrated from the rural areas to the urban industrialized areas with a hope of earning more in the city. Thus the metropolitan cities gradually grew in size with the establishment of industries and the inflow of workers. In the 20th century in the United States the growth of the urban city gradually spread to the outskirts of the city as well."

Click here to show/hide summary
Abstract
North Korea has been intimidating the United States with a series of nuclear threats since October 2002, when U.S. officials stopped the supply of heavy oils to the North in retaliation of its confessed production of nuclear warheads, violating agreements signed in 1994. Shortly after, North Korea withdrew from the Nuclear Nonproliferation Treaty (NTP) and agreements with the United Nations. The paper shows that while there is little proof that North Korea has nuclear weapons, it is strongly suspected that it does. The paper discusses the North Korean weapon issue.
From the Paper
"Many world leaders are suspicious about North Korea?s withdrawal from the NPT for many reasons. For one, it is a well-known fact that countries developing clandestine nuclear weapons programs take many measures to conceal information about these programs from the rest of the world (NTI, 2003). Therefore, without membership in the treaty, North Korea has made it difficult for world leaders to obtain information about the country?s weapon capabilities."

Abstract
Value engineering is viewed in many industries as an excellent strategy for reducing costs, increasing reliability and improving quality. It can be implemented in hardware and software; development, production and manufacturing; specifications, standards, contract requirements and other acquisition program documentation; facilities design and construction. Value engineering is a technique directed toward analyzing the functions of a project or product to determine "best value," or the best relationship between reliability and cost. In other words, "best value" is represented by a project or process that consistently performs its required basic function and has the lowest cost. In this context, the application of value engineering in a construction project can yield a better value when construction is approached in a manner that incorporates environmentally sound and energy-efficient practices and materials. This paper discusses the important relationship between reliability and value engineering, in an effort to explain how the two work harmoniously to improve projects or products. The paper includes a table.
From the Paper
"Many engineers are resentful of value engineering because they believe it often does the opposite of what it is intended to do, which is cut costs while improving reliability and value. Some say that many companies introduce value engineering solely to cut costs, rather than implementing it professionally and mainly for engineering purposes."
