The pattern reduction (PR) algorithm we proposed previously, which works by eliminating patterns that are unlikely to change their membership during the convergence process, is obviously one of the most efficient methods for reducing the computation time of clustering algorithms. However, it is limited to problems with solutions that can be binary or integer encoded, such as combinatorial optimization problems. As such, this study is aimed at developing a new pattern reduction algorithm, called pattern reduction over continuous space, to get rid of this limitation. Like the PR, the proposed algorithm consists of two operators: detection and compression. Unlike the PR, the detection operator is divided into two steps. The first step is aimed at finding out subsolutions that can be considered as the candidate subsolutions for compression. The second step is performed to ensure that the candidate subsolutions have reached the final state so that any further computation is eventually a waste and thus can be compressed. To evaluate the performance of the proposed algorithm, we apply it to metaheuristics for clustering.

Broadband over Power Line (BPL) technology has garnered significant attention lately due to recent advancements in solid state technologies and channel coding schemes. The successful application of BPL technology for in-home automation and networking has led to suggestions of applying BPL in other systems including ships. The application of BPL technology using the Shipboard Power System (SPS) as a potential communications network for ship automation systems has been proposed, to achieve recent U.S. Navy ship management concepts geared toward reducing ship manning while improving operational efficiency. This thesis presents an analytical model developed to examine the channel response characteristics and estimated throughput capacity of SPS cables. The work used a multiconductor transmission line theory based approach to model the channel response of SPS distribution lines and estimated the channel throughput capacity using a “water-filling” communication technique. This work found that BPL using the SPS holds a strong potential for use as a communications network for ship communication systems.

Classical hypergeometric functions and their relations to counting points on curves over finite fields have been investigated by mathematicians since the beginnings of 1900. In the mid 1980s, John Greene developed the theory of hypergeometric functions over finite fi elds. He explored the properties of these functions and found that they satisfy many summation and transformation formulas analogous to those satisfi ed by the classical functions. These similarities generated interest in finding connections that hypergeometric functions over finite fields may have with other objects. In recent years, connections between these functions and elliptic curves and other Calabi-Yau varieties have been investigated by mathematicians such as Ahlgren, Frechette, Fuselier, Koike, Ono and Papanikolas. A survey of these results is given at the beginning of this dissertation. We then introduce hypergeometric functions over finite fi elds and some of their properties. Next, we focus our attention on a particular family of curves and give an explicit relationship between the number of points on this family over Fq and sums of values of certain hypergeometric functions over Fq. Moreover, we show that these hypergeometric functions can be explicitly related to the roots of the zeta function of the curve over Fq in some particular cases. Based on numerical computations, we are able to state a conjecture relating these values in a more general setting, and advances toward the proof of this result are shown in the last chapter of this dissertation. We nish by giving various avenues for future study.

The drawbacks of the mechanical linear actuator which is applied to punch flexible printed circuit boards(FPCBs), are many components involved, low transmission efficient, and high proportion of energy consumption. In order to design and manufacture a device that can generate a rapid and high quality punching processes, the fundamental rules that can be followed are to use few parts with light weight design, good working piece, energy conserved, and perfect efficient. To improve the kinematic and dynamic characteristics of the existing mechanism, design, manufacture, and assessment are to be taken for developing new linear actuated mechanisms. The first step is to analyze the performance of the existing linkage actuator . The second step is to design a over-head cam mechanism of non-constant rotational speed to substitute the pulley and the rock arm according to the design specifications. The performance of the new type actuated device is superior to the existing mechanism, and this research had preliminary verified the viewpoint of the energy in high speed punching. The achievements of this research also provide references for linear actuator designers and high speed punching producers.

In past researches about the related factors of employee turn-over tendency, they paid most attention on employee satisfaction and available new jobs. Nevertheless, not only organization but also mental condition will influence the job satisfaction. Mental condition, including individualized psychological behavior and target, demarcate the life style of employee in organization ¡] 1988, Ansbacher ¡^. In addition, employee life style were evaluated quantitatively by Plummer¡] 1974 ¡^in three directions, activities, interest, and opinion. We combine both theories mentioned above to reveal the relationship of employee life style between inside and outside organization. Questionnaire and statistics are used to calculate and analysis the data collected from four companies of domestic airline in Taiwan in the research. Our study result shows that the background of employee has the influence on life style both inside and outside of organization, which leads to different tendency of employee turn-over. This is the first attempt to define the employee life style, both inside and outside of organization, and compare their turn-over tendency. Conclusively, the relation between employee life style and turn-over tendency is remarkable, which can be the reference of further researches about employee turn-over tendency related with life style.

This thesis is comprised of a literature review on the topic of social participation in the elderly, and a study examining the association between primary transportation mode used and social participation in community-dwelling seniors. A review of the literature showed that social participation in the elderly is associated with survival, health-related quality of life, functional ability, emotional well-being, and cognitive skills, and is also influenced by personal and environmental factors. The study indicated that primary mode of transportation used by seniors living in the community is associated with social participation; those driving, walking or using public transport had overall greater social participation than passengers and those using adapted transport/taxi. These findings are of interest to rehabilitation professionals and researchers working in gerontology, as well as to policy makers, since facilitating the use of readily available transportation modes is primordial to maintaining social participation of seniors living in the community.

Studies on chromosomal segregation in higher organisms have established a definite relationship between crossing-over and nondisjunction -- the two appear to be inversely correlated. Most of the experiments performed involve segregation from inversion and translocation heterozygotes. [...]

One Flew Over the Cuckoo’s Nest (1962) written by Ken Kesey tells the story at a ward where the patients who reside at the ward are exposed of oppression and humiliation by Nurse Ratched. One Flew Over the Cuckoo’s Nest: A Play in Two Acts (1963) written by Dale Wasserman is a theatrical play which is based on Kesey’s novel. The purpose of this essay is to argue that Nurse Ratched’s character is pictured as more evil in the novel than the play. In this essay, Ratched’s personality and outer looks was discussed as well as her methods she uses to humiliate and control the inmates. It was argued that Wasserman may have excluded information about Ratched’s character, so the actors have a chance to develop a personal view of Ratched. It was also argued that Ratched may have appeared as unnaturally evil if Wasserman had included all her evil traits, and thus picture her as a larger than life character.
