We first give a definition of simple sets of 1's in 4D binary images that is consistent with (8,80)-adjacency-i.e., the use of 8adjacency to define connectedness of sets of 1's and 80-adjacency to define connectedness of sets of 0's. Using this definition, it is shown that in any 4D binary image every minimal non-simple set of 1's must be isometric to one of eight sets, the largest of which has just four elements. Our result provides the basis for a fairly general method of verifying that proposed 4D parallel thinning algorithms preserve topology in our (8,80) sense. This work complements the authors' earlier work on 4D minimal nonsimple sets, which essentially used (80,8)-adjacency-80-adjacency on 1's and 8-adjacency on 0's. © Springer-Verlag 2004.

A Proposal of GA Using Symbiotic Evolutionary Viruses and its Virus Evaluation Techniques

引用

Journal of Advanced Computational Intelligence and Intelligent Informatics 2004年第4期8卷 421-425页

作者： Sakakura, Yoshiaki Taniguchi, Noriyuki Hoshino, Yukinobu Kamei, Katsuari Frontier Doctoral Program in Science and Engineering Ritsumeikan University Japan Graduate School of Science and Engineering Ritsumeikan University Japan Human and Computer Intelligence College Information Science and Engineering Ritsumeikan University 1-1-1 Noji-higashi Kusatsu Shiga525-8577 Japan

In this paper, we propose a Genetic Algorithm (GA) using symbiotic evolutionary viruses based on both the building block hypothesis and the virus theory of evolution. The proposed GA aims to control the destruction of building blocks by discovery, maintenance, and propagation of building blocks based on virus operation. We prepare a group of individuals and a group of viruses. The group of individuals searches for solutions and the group of viruses searches for building blocks. These searches are done based on the symbiotic relation of both groups. Also, our GA has two types of virus evaluation technique. In one type, each virus is evaluated by the difference of the fitness of an individual before and after virus infection. In the other type, all viruses are evaluated by the difference of the fitness of an individual before and after infection of all viruses. We applied the proposed GA to a minimum value search problem using a test function with some local minima far from the optimum. Finally, we also discuss the search behavior in the proposed GA based on each virus evaluation technique. © Fuji Technology Press Ltd.

ASEE 2004 Annual Conference and Exposition, "Engineering Researchs New Heights"

作者： Trytten, Deborah A. Shehab, Randa L. Rhoads, Teri Reed Fleener, M. Jayne Harris, Betty J. Reynolds, Anne Walden, Susan E. Moore-Furneaux, Sandra Kay Kvach, Elizabeth Warram, Kim R. Murphy, Teri J.

Interviews of twenty-six Industrial Engineering students and graduates were conducted during the first year of a three year study of the unexpected attainment of gender parity in the School of Industrial Engineering at the University of Oklahoma (OU). An analysis of the pattern of participant responses gives insight into industrial engineering (IE) student perceptions of IE. The perceptions were grouped into three broad themes: Career Profile, Discipline Profile, and Discipline Meta-Profile. The Career Profile includes the availability of multiple career paths and flexible careers in this discipline in addition to the potential for the attainment of status through entry into management. People-oriented, broad, and systems-oriented are terms that were used to describe the Discipline Profile. Discipline Meta-Profile is used to describe the participant's perception of other people's perceptions of industrial engineering (i.e. what IE students think other people think). These participants felt that other engineers think of IE as easy, or "imaginary" engineering. The participants also thought that the discipline is invisible, even to other engineers. While the meta-perception of IE might seem to be problematic for the discipline, many of the participants reject the meta-perception. Some participants recognized that IE's focus on people and systems is simply different than other engineering disciplines, not necessarily easier. Other participants felt the potential to enter into management outweighed the discipline meta-perception. One student summarized the response particularly well when he noted that IE is "inviteful" engineering.

International Conference on Vacuum Nanoelectronics (IVNC)

In this paper, the study of thermal CVD grown CNT field emitters in a triode amplifier configuration is reported. The DC characteristics of the CNT triode are investigated, including I/sub a/ vs. V/sub a/ for different V/sub g/. Moreover, DC parameters such as transconductance, amplification factor and anode resistance of the triode amplifier are determined. It was shown that a higher amplification factor can be achieved with optimum gate-anode-cathode spacing such that the cathode is effectively shielded from the anode by the gate but the anode still collects all electrons emitted from the cathode. High emission current at low gate voltage is key to achieving high transconductance. This can be obtained by optimum configuration of high-density CNTs array in a triode structure with a common gate.

In this study, various thicknesses of Pd catalytic films were deposited on Ti/Si substrates and pretreated with NH/sub 3/. The effects of catalyst deposition parameters and NH/sub 3/ pretreatment time (0, 1, and 10 minutes) on the size distribution of Pd catalytic particles, and subsequently, on the diameter and density of synthesized carbon nanotubes (CNTs) were investigated. The CNTs were synthesized by thermal CVD at 750/spl deg/C using methane (CH/sub 4/) as the carbon source, and a mixture of Ar/H/sub 2/ (80 vol.%/20 vol.%) as the carrier gas.

Medeiros Computer Science Program Graduate School of Engineering COPPE DCC/IM-Institute of Mathematics Federal University of Rio de Janeiro Rio de Janeiro Rio de Janeiro Brazil DEL/POLI-Department of Electronics and Computing Federal University of Rio de Janeiro Rio de Janeiro Rio de Janeiro Brazil

We start from a case study of an architecture company and move on to a framework of agents to identify and inform conceptual design. The processes and problems exhibited by the company involved are quite common and can be found in other similar companies. Our intent is to instrument the current process using agent technology, in an effort to improve global awareness during the conceptual design phase, allowing the designers to design so as to facilitate later steps and optimize the process as a whole.

Many new services have emerged to realize ubiquitous computing environments, owing to the increasing supply of mobile devices and more widespread Internet and wireless network facilities. We introduce the U-Campus (ubiquitous computing for campus) service. This study has been conducted through interdisciplinary research by four participating departments. The U-campus project is part of the UTOPIA project (Ubiquitous computing TOwn Project: Intelligent context Awareness), which covers town- and city-wide environments. Currently, a test bed for U-campus has been constructed to support various services suck as U-profile, U-messaging and U-campus tour guide services. Students, professors, school staffs, and campus visitors can easily access the various available campus services by using image-based sensors and mobile devices such as CDMA cellular phones or WiFi smart phones. The major purpose of this research is to provide a context-aware U-campus environment to users by utilizing sensors and mobile devices currently available in the public sector and the marketplace.

Journal of Computing Sciences in Colleges 2004年第3期19卷

作者： Michael L. Nelson David Rice Graduate Program Director Computer Information Technology International College 8695 College Parkway Ft Myers FL Department Chair Computer Information Technology International College 8695 College Parkway Ft Myers FL

There are several considerations in creating a graduate program. Administrative concerns, accreditation issues, needs assessments, faculty teaching load, faculty compensation, additional faculty needs, and comparisons with other programs are all important, not to mention creating a "good" curriculum with a set of appropriate course syllabi and then "marketing" that program. This experience paper details the approach that was used quite successfully at International College, and also discusses the "speed bumps" encountered and "mid-course corrections" taken during the first year of the program's existence.

One of the main factors that impede the practice of the telemedicine is not the lack of new technologies for the communication, but the lack of studies on the use of the technology already installed in the distant areas, in way to be used of a rational way. The objective of the telemedicine is to provide help to the cares with the health with quality the distant areas of the great attendance centers. Therefore, it cannot ignore the fact that these areas do not make use of point technologies for communication. Then, it is justified the need to accomplish studies that facilitate the practice of the independent telemedicine of the installed technology. Then, the objective of this work is to use as pilot an unit of remote health, contributing with a support system that allows the practice of the telemedicine using the technology of available transmission in the respective place, avoiding that the factor cost is a barrier for the telemedicine projects and can begin an improvement process in the quality of the attendance in units of distant health of the great centers of medical attendance.
