Intelligent Control Mechanism of Part Picking Operations of Automated Warehouse

This paper studies the part picking operations of a ut omated warehouse. It assumed the demand of picking orders of automated warehouse are dynamic generated. Once the picking orders of certain period of time are kn own, it is necessary to decide an efficient order picking sequence and routing t o minimize the total travel distance to complete those orders. Assumed there are n i items to be picked in order O i. Each item in the picking ord er is located in different locations in the warehouse. Since i...     

Security Analysis of Discrete Logarithm Based Cryptosystems

0 IntroductionNowthere are many well known cryptosystems based ondiscrete logarithms , such as the ElGamal cryptosys-tem[1]and the digital signature algorithm(DSA)[2]. Discretelogarithms have many advantages . Breaking the discrete log-arithm modulo pri mepappears to be somewhat harder thanfactoringintegern,and elliptic curve cryptosystems may usemuchsmaller keysizesthan RSA-basedcryptosystems of com-parable security.The discrete logarithmproblemover a group can be bro-ken down into a numb…     

Resource Search in Unstructured Peer-to-Peer System Based on Multiple-Tree Overlay Structure

We propose a multiple-tree overlay structure for resource discovery in unstructured P2P systems. Peers that have similar interests or hold similar type of resources will be grouped into a tree-like cluster. We exploit the heterogeneity of peers in each cluster by connecting peers with more capacities closer to the root of the tree. The capacity of a peer can be defined in different ways （e.g. higher network bandwidth, larger disk space, more data items of a certain type etc.） according to different needs of users or applications.     

道琼斯工业指数与纳斯达克指数的非线性协整分析

首先对道琼斯工业指数进行分整分析,长记忆的道指被分数维差分得到平稳时间序列;进而对纳指也进行分数维差分.由于两指数的分整阶数不同,故不存在线性协整关系,所以,文章着重讨论两指数的非线性协整关系.     

舰载超视距雷达背景杂波统计特性分析

海杂波的统计特性对于岸基与舰载表面波雷达目标检测算法的设计非常重要。岸基雷达测试下海杂波的统计特性已有论述 ,主要阐述舰载雷达情形下背景海杂波的理论与数学统计模型 ,并提出了海杂波序列的参数自回归模型 ,对海杂波的重要统计参数如相关性进行了统计分析 ,最后得出了舰载雷达情形下一阶与二阶海回波皆为正态分布的结论 ,为在舰载雷达情形下进行信号检测奠定了理论基础。
