Keywordfinite field, self-reciprocal polynomial, irreducible polynomial
AbstractThis paper proposes a method of generating irreducible self--reciprocal polynomials by using even polynomial over $F_q$, where $q$ is odd prime. First, we prepare an irreducible self--reciprocal polynomial $F(x)$ in $F_q[x]$ of degree $2m$. Then, the proposed method repeatedly generates a lot of irreducible self--reciprocal polynomials of degree $2m$ by using $F(x)$ as a seed. In this paper, the set of the generated polynomials is called {¥it loop}.This paper also shows a method for preparing a seed of another {¥it loop}.

KeywordISO13584, IEC61360, PLIB dictionary, Parts Library, TBT
AbstractThis paper devises a compilation procedure of a dictionary conforming to ISO standards, the so-called PLIB dictionary, dedicatedly for a mechanical element of 'chain'. First, a standardized identification hierarchy of the chains is constructed on the basis of ISO 13584-42, and then a new compilation procedure of the PLIB dictionary is described, which consists of assigning BSU (Basic Semantic Unit) codes to each family and each property of of chains as well as to each incidence of property to family, and constructing a physical file on the basis of ISO 10303-21 by means of a mapping system developed origi-nally by the authors.

TitleVirtual Training Environment Providing Force Feedback for Motoric Improvement of Upper Extremity
Author*Atsushi Kanbe, Yukihiro Matsubara, Noriyuki Iwane (Graduate School of Information Sciences, Hiroshima City University, Japan)
Pagepp. 129 - 132
Keywordmotor training support system, virtual reality, force feedback, upper extremity
AbstractWe suggest a motor rehabilitation support system for upper extremity with force feedback. A client throws a ball underhanded using a force feedback device, and then the client can receive rehabilitation for an arm's motion sensing feel of weight. Throwing motion is difficult, so we built training environment that the client can select challenge level that is suitable to his/her ability. Furthermore, the system can indicate movement of arm. We evaluated basic functions of our system. Participants of experiments could throw well by watching an indicator of moving the upper extremity and receiving force feedback.

TitleEvaluation of N-myristoylation Prediction Tool using Machine Learning

Pagepp. 133 - 136
Keywordmachine learning, N-myristoylation, sequencing analysis, characteristics extraction
AbstractProtein sequences constitute molecular complex in an organism. However it is difficult to find a sequence rule such as cascade reaction signals, post translational modification signals and so on.These sequence signals perform an essential role in regulating cellular structure and function. In previous study, we could find sequence rules of N-myristoylated proteins easily with computational approach. Subsequently, we have developed a CGI tool to predict N-myristoylated proteins with their sequence rules. In this study, we performed accuracy evaluation of our developed CGI tool. As a result, we show that developed CGI tool predict N-myristoylated proteins effectively with characteristics of N-myristoylated protein sequences.

TitleA Parallel Simulated Annealing on Distributed Computing Resources
Author*Masashi Murayama, Morikazu Nakamura (University of the Ryukyus, Japan)
Pagepp. 137 - 140
Keywordparallel processing, simulated annealing
AbstractIn this paper, we present a parallel simulated annealing (SA) on distributed computing resources. The parallel SA include two types of cooperation mechanism: inner group and inter group cooperations. In the inner group cooperation, SA processes start from the same initial point, however, move to different direction. That is, two concepts: concentration and diversity are included. On the other hand, the inter group cooperation is for load balancing which is performed based on search load factor. Therefore it is useful to balance searching load by reassigning dynamically processors from light load groups to heavy load groups. Computer experiment evaluates effectiveness of the proposed parallel SA.
