Many fires which cannot extinguish the fire will break out. Therefore, It is required to carry out the simulation of the fire spread form, to carry out damage prediction, and to take the measures according to damage immediately after earthquake generating. In this study, the micro model fire spread simulation method for every house has been developed. In order to verify the validity of this simulation method, reappearance of the fire of the Mikura-Sugawara, Nagata-ku, Kobe-shi area in the Hyogoken-Nanbu earthquake of 1995 was tried. Moreover, the fire generated in the past in Nagoya-shi was investigated. It, the influence of building collapse by earthquake damage, fire-extinguishing activities, and jumping fire were taken in for the simulation. Establishment of the more accurate fire spread simulation method was aimed at. The process of a simulation in this study is described. It is the beginning first, the simulation region is elected. A position, building form, building structure, and the number of stories are file-ized about the building in the region. Calorific function, distance between buildings, wind velocity, direction of the wind are given to the file-ized date, and a simulation is performed. The result, the simulation of the form near the actual spread of a fire was able to be carried out. The obtained fire spread speed became actually near as compared with the conventional formula. The fire spread situation of an earthquake fire and the fire-fighting effect were predicted in the Habashita, Nishi-ku, Nagoya-shi area with the application of this simulation method. 2001-03-30T15:00:00Z http://hdl.handle.net/11133/1154 タイトル: 三次元二足歩行シミュレーションの研究 著者: 加藤, 啓路; 平松, 誠治; 加藤, 厚生 抄録: The analysis of human walk is one of the main topics of the bio-mechanism. Measurements of human walk have been done in active by many researchers until now. On the analytical research various experimental approaches were used, but parameters of the human body and environment cannot determine clear. Then recently on the synthetic research the computer simulation approaches are noticed. In computer simulation, unknown parameters of environment and human body can be supposed easy. A problem of this study is that our model is comparatively simple. Therefore, it is not possible to sufficiently reflect anatomical advantage and neurophysiological features of the human body. In this study simulation model is constructed by three-dimensional model of locomotion based on the anatomy. Results of the simulation are estimated by the experimental result of human walk. 2001-03-30T15:00:00Z http://hdl.handle.net/11133/1155 タイトル: 地質別にみた地震動の強さを表す指標の距離減衰および各指標間の関係について 著者: 村松, 幸則; 正木, 和明 抄録: Strong motion records during the Yoro Earthquake on April 22,1998 wereobserved at 298 sites by the strong motion network organized by Nagoya University. Parameters that indicate seismic intensity of strong motion of ground surface such as maximum acceleration, maximum velocity, maximum displacement, Housner's spectral intensity SI and JMA seismic intensity were calculated by FUKUWA et. al. (1999). The attenuation models of these parameters were studied according to soil age at the sites. The relations among these parameters were also discussed for making clear which is suitable as the parameter of seismic intensity. 2001-03-30T15:00:00Z http://hdl.handle.net/11133/1148 タイトル: 楕円曲線法による素因数分解に関する実験的考察 著者: 小池, 慎一; 山住, 富也 抄録: We show some characters of the elliptic factoring method (ECM). In some trial factoring the Mersenne Number M137,7's are success and 5's failed. This is its probablistic character. Also we show that for factoring, an order of curve must be decomposited to some small prime factors. At last, using random number instead of prime, a number is factorized. 2001-03-30T15:00:00Z
