Optical Color Pattern Recognition with High Discrimination Capability Using Binary Amplitude Phase-Only Filters

The possibility of improving the discrimination capability (DC) in color pattern recognition is analyzed. In each channel, red, green and blue (R, G, B), a region of support is designed to improve the behavior of the Phase Only Filter matched to the corresponding component of the target. The procedure of optimization is based on the analytical expressions which give the DC in R, G, B channels, for real valued input scenes. Computer simulation results are presented and discussed.     

基于有向图规划的最佳物流路径策略分析及应用

本着重讨论基于有向图规划的最佳物流路径策略分析及应用。通过分析物流结构的一般模型，提出最短路径和关键路径物流策略分析方法，给出具体的分析和计算方法，并举实例加以说明，为解决现代物流结构性中存在的系统设计和运作等问题提供理论依据和技术方法。该方法也适用于其他动态规划问题的研究。     

Electric vehicles: effect of the availability threshold on the transportation cost

This paper addresses the transportation problem using public electric cars. The management of this new form of transportation means considering two issues: the redistribution of the cars among the stations (in this paper, we assume that this issue is perfectly settled, the number of cars needed at each station being available at any time), and the recharge problem that we describe in this paper. At each station, a decision concerning the cars which should become available to customers, has to be taken. We assume that a vehicle is available when its charge is greater than a given threshold. Our goal is to optimize this threshold. Copyright © 1999 John Wiley & Sons, Ltd.
