未知环境下的多机器人协作围捕方法

针对未知环境下的多机器人协作围捕进行了研究.首先介绍了围捕任务,然后给出了在未知环境下多机器人协作围捕的算法思想及控制流程.围捕任务中,对机器人设计了4种队形,采用有限状态机在不同队形之间进行切换.最后,在Vc++平台下进行了动态围捕仿真,验证了算法的有效性.     

浅析俄罗斯军事刑罚制度对我国的启示

我国军事刑法与俄罗斯军事刑法都分别在本国的普通刑法中用专章加以规定,相似之处很多。在军事刑罚方面,俄罗斯有很多专门针对军人、军事犯罪的特别刑罚很值得我国借鉴。对比中国和俄罗斯两国的军事刑罚,找出我国在军事刑罚方面的不足之处,借鉴俄罗斯军事刑罚制度中的可取之处,完善我国的军事刑罚制度,使之更适应我国军事、国防的发展需要,有利于预防军事、军人犯罪,提高我国军队战斗力。     

一种以太网拓扑发现算法

局域网内部的拓扑对于现代网络管理非常重要,而网络层拓扑发现对于局域网内部的拓扑是不可见的。文章提出了一种基于生成树协议(STP)的拓扑发现算法,利用简单网络管理协议(SNMP)读取交换机MIB中的生成树信息,可以得到局域网内设备间的连接。该算法不需要交换机地址转发表(AFT)完整,也能发现交换机的备份链路和集线器以及不支持SNMP的交换机。经分析,该算法是一种简单的,准确的以太网拓扑发现算法。     

军队人力资源培训问题的整数线性规划模型

文章研究了军队人力资源培训问题,并基于时间和费用两个指标,建立了一个满足培训时间约束且费用最省的0-1整数线性规划模型,给出了基于Lagrange松驰分解的模型求解算法。在算法中,采用一种简单可行的Lagrange乘子更新方法代替传统的次梯度法。另外,文章证明了算法获得最优解的两个充分条件,计算实例初步表明给出的算法是行之有效的。     

A multilevel passenger screening problem for aviation security

Passenger prescreening is a critical component of aviation security systems. This paper introduces the Multilevel Allocation Problem (MAP), which models the screening of passengers and baggage in a multilevel aviation security system. A passenger is screened by one of several classes, each of which corresponds to a set of procedures using security screening devices, where passengers are differentiated by their perceived risk levels. Each class is defined in terms of its fixed cost (the overhead costs), its marginal cost (the additional cost to screen a passenger), and its security level. The objective of MAP is to assign each passenger to a class such that the total security is maximized subject to passenger assignments and budget constraints. This paper shows that MAP is NP‐hard and introduces a Greedy heuristic that obtains approximate solutions to MAP that use no more than two classes. Examples are constructed using data extracted from the Official Airline Guide. Analysis of the examples suggests that fewer security classes for passenger screening may be more effective and that using passenger risk information can lead to more effective security screening strategies. © 2006 Wiley Periodicals, Inc.

On the bivariate negative binomial distribution of mitchell and paulson

The bivariate negative binomial distribution of Mitchell and Paulson [17] for the case b = c = 0 is shown to be equivalent to the accident proneness model of Edwards and Gurland [4] and Subrahmaniam [19,20]. The diagonal series expansion of its joint probability function is then derived. Two other formulations of this distribution are also considered: (i) as a mixture model, which showed how it arises as the discrete analogue to the Wicksell-Kibble bivariate gamma distribution, and (ii) as a consequence of the linear birth-and-death process with immigration.     

State information lag markov decision process with control limit rule

In the framework of a discrete Markov decision process with state information lag, this article suggests a way for selecting an optimal policy using the control limit rule. The properties sufficient for an optimal decision rule to be contained in the class of control limit rules are also studied. The degradation in expected reward from that of the perfect information process provides a measure of the potential value of improving the information system.
