An algorithm for a class of loading problems

The loading problem we consinder is to assign a set of discrete objects, each having a weight, to a set of boxes, each of which has a capacity limit, in such a way that every object is assigned to a box and the number of boxes used is minimized. A characterization of the assignments is offered and used to develop a set of rules for generating nonredundant assignments. The rules are incorporated into an implicit enumeration algorithm. The algorithm is tested against a very good heuristic. Computational experience shows that the algorithm is highly efficient, solving problems of up to 3600 0-1 variables in a CPU second.     

An algorithm for 0-1 multiple-knapsack problems

The 0-1 multiple-knapsack problem is an extension of the well-known 0-1 knapsack problem. It is a problem of assigning m objects, each having a value and a weight, to n knapsacks in such a way that the total weight in each knapsack is less than its capacity limit and the total value in the knapsacks is maximized. A branch-and-bound algorithm for solving the problem is developed and tested. Branching rules that avoid the search of redundant partial solutions are used in the algorithm. Various bounding techniques, including Lagrangean and surrogate relaxations, are investigated and compared.

多传感器式诱导维修系统的设计与实现

针对战场装备抢修中维修作业时间紧、任务重、难度大和专业维修人员少的问题,提出了多传感器式诱导维修系统体系结构,开发了一套基于增强现实技术的诱导维修系统。系统主要由5个模块构成。通过PST跟踪仪和基于无迹卡尔曼滤波的多传感器跟踪算法完成跟踪注册,结合语音和手势识别进行人机交互,通过构建无线通讯网络和实现数据分布式处理拓展了系统的适应性和实用性。以某型装备电磁铁更换为例,对系统功能进行了验证。实验对比说明了与纸制维修手册和普通移动终端相比,该系统能更为高效地指导维修人员完成维修任务。     

The nexus between military expenditures and economic growth in the BRICS and the US: an empirical note

This empirical note re-examines the causal linkages between military expenditures and economic growth for the BRICS countries (Brazil, Russia, India, China, and South Africa) and that for the USA during the period 1988–2012. Results of Granger causality tests show that military expenditures influence economic growth in the USA, economic growth influences military expenditures in both Brazil and India, a feedback between military expenditures and economic growth in Russia, and no causal relation exists between military expenditures and economic growth in China and South Africa. The findings of this study can provide important policy implications for the BRICS countries and also for the USA.
