The damage tests of microprocessors were carried out under γ-rays. The PIC microprocessors produced by Microchip Technology Inc are inexpensive and popular CPU. so that they are used in autonomous small robots.Under γ-rays,we tested the reliability of the PIC12F675 and PIC16F84A that belonged to mid-renge of the 8-bit PIC microprocessor's family. The source of γ-rays was Cesium 137.The source of γ-rays was mounted on the PIC directly.The PIC's plastic package was scraped by 0.7 mm in order to increase the exposure dose of the γ-rays to silicon chip in the plastic package of PIC. The LEDs connected to I/O Ports of the PIC were blinked by programs,Which was monitored by video camera.Seven days radiation ofγ-rays did not affect the function of PIC microproccssors.

To improve security awareness of end-user, we designed and implemented the visualization system of packet header that represent the condition of network communication. We implemented our systems using Microsoft Visual Studio 2005 with Winpcap library and the development traffic, protocol and the time it captured a packet.

In this paper, we investigate of the repeated janken gameto estimate characteristic of game agents. In the repeated janken game, players repeat single"janken"reiteratively. The reppeated janken game has strategy. for examples, random strategy,fixed strategy, repeated strategy,history-based strategy that uses history of opponent hands. We analyze superiority of strategy by computer simulations. As a result, we show superiority of history-based strategy.

The purpose of this research is to decrease the complicated selection operation in the Japanese input of a Personal Digital Assistant by using the Classified Examples Dictionary.Miniaturization technology for the Personal Digital Assistant using an interface without a keyboard has progressed.However,the method of a Japanese input is a problem.The Personal Digital Assistant has a characteristic interface using a small touch panel.Some techniques exist to help input characters.For example,the Graffiti,prediction conversion including POBox,etc. However,for any technique's writing a Japanese long sentence,especially a Japanese e-mail document,it becomes a big burden for a user.In many cases,e-mail documents are constituted combining certain sentences.So it is significant,if the dictionary which arranged many examples is drawn up and Japanese is inputted using that dictionary.In this paper,it is called The Classified Examples Dictionary.The purpose of this research is to ease a user's burden by using the dictionary.

This paper aims to grasp and evaluate the present condition of the main streets in central Taipei City that was once under the occupation of japan. At frrst,the way of utilization, the structure and so on of each street are investigated by the field surveys. Then, the streets are evaluated from the viewpoints of safety,smoothness,scenery,location etc. based on japanese and Taiwanese students' consciousness. As the results, it is made clear that japanese students tend to regard "location" as more important factor and Taiwanese students tend to regard "safety" as more important factor in the evaluation of the streets.

Yes. The principle of a kaleidoscope can magnify tiny differences of dot patterns. Human brains can recognize a small difference of patterns especially in the case of patterns having some symmetry. The kaleidoscope generates 3-fold rotation symmetry patterns by using the mirrors so that we can recognize tiny differences of time-series by embedding the oeak-value on the scope of the kaleidoscope. We demonstrate this effect using synthetic data and then apply this method to RF echo signal of ultrasonic diagnostic system.

Claude-Nicolas Ledoux (1736 --1806) is one of the visionary architects in the18th century France. Recently, the studies on the architect Ledoux are progressing inside and outside the ccountry. Accordingly,the Ledoux's whole figure is making itself clear gradually. In this paper,we chiefly describe the details about the Ledoux's project "a triumphal arch in Kassel". We publish it as introduction to minute research into one of the most impotant architects in the age of French Revoltion, and more profound investigation of the transformation in architectural thought between France and Germany.

A molecular dynamics simulation was carried out in order to investigate a peculiar permanent densification phenomenon for SiO_2・K_2O・CaO・SrO glasses of an invert composition, i.e., the fraction of SiO_2 lower than 50 mol%. The phenomenon was previously observed by an experiment by high pressure treatment: the densities of permanently densified glasses exhibit a maximun value at 3 GPa (Kawamoto et al., J. Non-Cryst. Solids, 284, 128(2001)). In our simulation, the density profile was qualitatively reproduced: the density after decompression exhibits a maximum at treatment pressure 12 GPa. After decompression, the five-and six-coordinated Si species, which promote a network at high pressure, remain mostly at treatment pressure of 12 GPa, where the density exhibits a maximum.

The purpose of this study is to understand what the actual situation of "the secret base playing". We also investigate how children grasp places and environment through the play. We divided an aspect of secret base into three types based on the writing of Masaki Ando. It is concluded that "the secret base playing" is a symbol of another-world such an un-dairy.

A numerical simulation of Hodgkin-Huxley model was carried out by using a Runge-Kutta method. In the numerical simulation, the functions of Numerical Recipes in C were used for solving the Hodgkin-Huxley equation. The accuracy of numerical solutions was discussed for both simple Runge-Kutta method and adaptive stepsize control Runge-Kutta method. The difference between simulation performed by using float type variables and one by using double type variables was also discussed. A large neural network of Hodgkin-Huxley neurons was carried out. A synchronization in the neural network was observed by changing the weight of synaptic transmission.

In this paper,we construct the character search amusement demonstration system in explaining basic image processing techniques for the PBL lecture.At the Graduate School of Engineering,University of Fukui,new program for graduate student, PBL,starts on last October.One of lectures at the Deparment of Human and Artificial Intelligent Systems opens a copse,"Construction of amusement demonstration system in promoting an investigation" as one part of PBL. The main purpose of the lecture is to construct an amusement demonstration system which helps better understand in to our investigation for people. My major filed is in medicali image processing,and especially,I investigate 3D filter design for CT images in improving visibility RI capsules in prostate cancer treatrment. Then, in explaining my study for undergraducate students,it is important to induce intensest in image processing techniques.Therefore,we construct the character search amusement demonstration system. Through the lecture for 1st degree undergraduate students,I introduce major filed by means of the system.The system is quite to explain and almost students exhibit interest in my major filed.
