Thermoluminescence Spectra of Laser-Irradiated CdS-Doped Glasses
Tadaki MIYOSHI, Hidenori NOGUCHI, Kohei UOSAKI, Teruhisa KANEDA
要旨
Thermoluminescence spectra have been measured in laser-irradiated CdS-doped glasses. The thermoluminescence spectra are similar to photoluminescence spectra. This indicates that the thermoluminescence is attributable to radiative recombination of electrons and holes in CdS nanocrystals.

宇部市の道路ネットワークを対象とした交通渋滞シミュレーションの実行(第2報)
福田桂大, 久井守
要旨
This paper is a further report to our preceding one that performs traffic simulations of traffic flow and congestion on the signalized network in Ube city and tries to improve the reproduction ability of current traffic situation by adjusting simulation conditions in heuristic manner. Time span of simulation is 24 hours including peak hours in the morning and in the evening when traffic congestion may occur. A microscopic simulation that has been developed based on discrete model is used. One of the feature of the simulation is that vehicles are assumed to take either of two mode of stopping and running to increase calculation efficiency. Another feature is that route selection is modeled.

山口県における耐候性鋼橋の表面付着塩類調査
麻生稔彦, 烏田晃平, 大屋誠, 武邊勝道
要旨
Weathering steel has been used increasingly for structural components of steel bridges due to high resistance of corrosion. It can be used for constructions without anticorrosion coating. However, in some cases,very severe surface corrosion has been observed. This paper reports accumulating salt on the weathering steel bridges in Yamaguchi prefecture. Accumulating salts on bridges were analyzed by ion-exchange chromatography. Composition and quantity of accumulating salts, relationship between rust thickness and Cl- are discussed. Regional differences of accumulating salts are also described.

地方都市における橋梁の資産価値評価に関する一考察
麻生稔彦, 立道孝大, 榊原弘之, 井原慶子
要旨
In the near future, most of infrastructures that were built in the period of high growth of economy will be needed to repair. Therefore a large amount of budget will be required for the maintenance. Asset management is indispensable in order to use a budget efficiently. In this study, value evaluation of bridges in a local city was carried out. Values of bridges are considered as the sum of a material value and social value. A material value is analyzed by the cost of repairing with time progress. Social value was computed as user cost in road network model analysis.

遺伝的アルゴリズムを用いた災害時避難所の最適配置に関する研究
麻生稔彦, 松本頼一, 森下和久
要旨
In recent years, the damage by natural disasters is increasing in Japan. A natural disaster takes a human life and serious blow to economic activities. In order to protect a human life from a natural disaster, the usual preparation is very important. Therefore, local government installs shelters. However, prediction of evacuation route and arrangement of shelters are not considered. This study aims to clarify evacuation behavior in Ube city using evacuation simulation. The simulation was performed by network model. Based on the results of evacuation simulation, optimal arrangements of shelters are also carried out.
