Abstract
This paper provides an application oriented state-of-the-art review of smart materials and magnetostrictive actuators in aeronautical design. Smartness describes self-adaptability, self-sensing, memory and multiple functionality of the materials or structures. The paper shows that these characteristics provide numerous possible applications for these materials and structures in aerospace, manufacturing, civil infrastructure systems and biomechanics. Active vibration and acoustic transmission control, active shape control and active damage control are some of those areas which have found attractive applications for smart materials and structures. Examples of specific applications are micro-positioning, vibration isolation, fast acting valve and nozzles, transducers, luxury car shocks, and active engine mounts in aircrafts. The paper shows that system integration, mass and energy consumption reduction, elimination of moving parts in actuators and collocation between actuator and sensor are some of the benefits of using smart materials. Those smart materials covered in this paper are primarily piezoelectric, shape memory alloys and magnetostrictive.
From the Paper
"Along these lines there is growing interest in the design and control of smart structures systems with embedded sensors and actuators that provide enhanced ability to program a desired response from a system. The ability to sense real-time conditions, i.e., the factors that contribute to turbulence and therefore resistance in a given environment, would be welcome and useful. Applications of interest include: (a) smart helicopter rotors with actuated flaps that alter the aerodynamic and vibrational properties of the rotor in conjunction with evolving flight conditions and aerodynamic loads; and (b) smart fixed wings with actuators that alter airfoil shape to accommodate changing drag/lift conditions. In these and other examples, key technologies include actuators based on materials that respond to changing electric, magnetic, and thermal fields via piezoelectric, magnetostrictive and thermo-elasto-plastic interactions."

Abstract
This paper explains that smart materials are devices, which can sense various stimuli from outer environment such as thermal, electrical and magnetic changes and can respond accordingly; basically, they are materials that sense and respond like living things. The author points out that two families of passive seismic control devices exploiting the peculiar properties of SMA kernel components have been implemented and tested within the MANSIDE project (Memory Alloys for New Seismic Isolation and Energy Dissipation Devices: Special braces for framed structures and isolation devices for buildings and bridges. The paper states that, with these smart materials, engineers are able to build the best and safest structures where possible catastrophic changes in the environment are sensed and precautions are taken directly. 10 figures.

From the Paper
"The first experimental demonstration of the piezoelectric properties in relation to crystal structure was published in 1880 by Pierre and Jacques Curie. This effect was considered quite important and was referred to as "piezoelectricity" in order to distinguish it from other areas of scientific phenomenological experience such as "pyroelectricity" (electricity generated from crystals by heating). As an aside, piezoelectrics also tend to be pyroelectrics. The Curie brothers did not predict that crystals exhibiting the direct piezoelectric effect (electricity from applied stress) would also exhibit the converse piezoelectric effect (stress in response to applied electric field). This property was mathematically deduced and hypothesized by Lippmann in 1881. The Curies then confirmed the existence of the converse effect, and continued on to obtain quantitative proof of the complete reversibility of mechanical deformations in piezoelectric crystals."

The paper relates that this sort of technology has been in development for a decade or so and has been pursued by a number of companies, some in association with ERG, some acquired by ERG, and some concentrating on different aspects of the market than ERG.
From the Paper
"ERG Smart Cards is a company offering the means for widespread use of smart cards, a system allowing for monetary value loaded onto "smart cards" with embedded microprocessors for recording transactions and calculating changes in value. This sort of technology has been in development for a decade or so and has been pursued by a number of companies, some in association with ERG, some acquired by ERG and some concentrating on different aspects of the market than ERG. ERG today is in a strong position for the future but is also faced with a reduced stock price because of problems with its association with Motorola, once a linchpin for the company and now a drain on the stock price. CEO Fogarty has to determine whether to continue to pursue the company strategy of concentrating on large-scale projects or chase smaller tenders."

"SMART CARDS: THE TECHNOLOGY, ITS ADOPTION, COMPETITION IN MARKETING SMART CARDS, AND SECURITY
Introduction
This research examines smart card technology, the adoption smart card technology by transaction card issuers in the United States, competitive strategies in the marketing of smart cards, and security issues involving the use of smart cards. One focus of this research is on the adoption of smart card technology in the United States, as opposed to the introduction of the technology, because the introduction of smart card technology in the United States occurred several years ago. The acceptance of smart cards by consumers and businesses in the United States, however, has been a slow process. The widespread use and general acceptance of smart cards in Europe contrast sharply ..."

Abstract
This paper is an analysis of the Smart Growth Initiative and its affect on the population that is searching for affordable housing. The author details the initiative including its goals, target audience, environmental concerns and successes and failures. The paper also includes the discussion of economic, social and environmental costs of current development patterns and how smart growth provides alternatives to current development patterns, in addition to investigating what it means for affordable housing quality and supply. Land use and planning strategies are also discussed in detail. The author also presents and analyzes a case study of Accessory Dwelling Units (ADU?s) in Cary, North Carolina as a means for the reader to see an actual example of how smart growth can affect affordable housing.
From the Paper
"Current development patterns were driven mainly by public policy. The development patterns are characterized by a separation of uses, dependency on automobiles and the consumption of space in suburban and ex-urban areas. This pattern is supported by strict zoning regulations, transportation systems and a lack of coordination in planning. This is important, because these factors are also obstacles to making changes.
The booming economy of the 1990?s has seen housing and rental costs increase at more than twice the rate of inflation. This has meant that many low-income owners are now unable to find affordable housing. Low-income earners are forced into substandard housing, forced to live in areas where affordable housing is available but at the expense of good security or good schooling, or forced to be homeless."

"The primary physical location will be in California due to the legal advantages of such a location; to start, the manufacturing plant/office will be centrally located in a small Central Valley city called Chowchilla. There were two main factors that helped influence my decision; rapid delivery time anywhere in the state and the amount of potential customers (farmers). Being in the heart of California, Eco-Smart will be able to fill any California customer's orders within 24 hours. No competitors can offer that as of now. The Central Valley is not only a prime spot for the manufacturing plant; it also offers the largest base of potential customers. Nearly half of the cropland and more than half of the irrigated acreage in California lie in this region, which is home to eight counties -Fresno, Kern, Kings, Madera, Merced, Stanislaus, San Joaquin and Tulare. A third of the state's farms and farmland are located in this region (California Farm Bureau, 2)."

From the Paper
"The despreaded sequence is forwarded to the multiuser detector unit. In this unit, performance enhancing signal processing such as beam forming, RAKE combining including channel estimation, antenna diversity combining, multiuser detection and error control decoding can be included. If perfect channel information is available, beam forming, RAKE and antenna diversity combining merely represent linear transformations to obtain a minimal set of sufficient statistics. From the fundamental digital communication theory, this is in fact equivalent to filtering matched to the received waveform in order to maximise the signal-to-noise ratio (SNR)."

From the Paper
"On the surface, the smart card is a means of gathering up loose change and loose economic threads, and moving toward a cashless society. In the real world, almost everyone carries paper money, coins, credit cards, checks, and the occasional debit card. These are the currently accepted financial instruments used in everyday transactions of money and credit. One or all of these instruments are accepted by whomever we choose to do business with. As the year 2000 draws near, the likelihood exists that stored value cards, often known as smart cards, will all but eclipse the use of small bills and coins (Morrall, 1995)."

Abstract
This paper examines the topic, New Urbanism, synonymous with the term "Smart Growth" which is a way to develop land efficiently, whether it may be a new development using open space land, or a redevelopment of a part of an inner city- called "infilling". The paper explores the ten principles that New Urbanism is guided by and gives examples of developments across the country that have used this method and prospered.
From the Paper
"Small, picturesque towns like Nantucket and Savannah dot the eastern landscape of the country. These towns are the illustration of the principles America was founded upon: closeness, unity, community, and family. The neighborhoods were compact and had mixed-uses. Everything a family needed in the normal course of the week was all within walking distance. There was a town square where the townspeople met and talked. In the youth of this country small developments like these were common, however in the last 50 years America has seen development practices take a turn for the worse. The current practice of building suburbs nationwide sprang up after World War II, and development has sacrificed hundreds of thousands of acres to this practice ever since. Now the majority of U.S. citizens now live in automobile-oriented, unattractive suburbs full of strip malls and four-lane roads with four-foot sidewalks. Although this is still the norm, there is a new kind of development that is making an impact on the way communities are built. This new method, called New Urbanism or Smart Growth, has caught on in the last 20 years and is now popping up all over the country. New Urbanism is a way to combat ugly urban sprawl, replacing it instead with small, interconnected communities that are pedestrian-friendly and contain housing, work places, shops, entertainment, schools, parks, and other amenities essential to the daily lives of residents, all within easy walking distance of each other. New Urbanism involves using the principles it sets forth to fix and redevelop existing cities, called ?infilling?, as well as to create new, high-density, compact towns and villages."

"General Comments
This essay summarizes and comments on the various religions discussed in Ninian Smart's The World's Religions. The human race has developed many forms of religious belief. In so many ways, a person's faith seems to be a matter of opinion. However, it should not be surprising that this is so. Humanity consists of many groups of people, and each group will have its own perspective and beliefs about philosophical and theological subjects. If we understand something concerning the wide variety of faiths in the world, we will have learned something about the diverse cultures and societies of this planet.
Consequently, the study of comparative religion is of tremendous importance for this reason. There is no one way or right way to think in this world. The truth of the matter is..."

Abstract
This paper argues that the current trend towards being skinny is causing serious harm to teenage girls. The author argues that this obsession is the leading cause of eating disorders and sickness in today's society.
From the paper:
"Eight million or more people in the United States have an eating disorder, ninety percent are women and eating disorders usually start in the teens but may begin as early as age eight. To me, the center of this problem is young women ignoring that they know what they are doing is wrong. If girls think that all guys just look at the body they are wrong. There are a few, but they grow up. You girls just can?t ignore the facts."
