基于粒子群优化的模糊交通控制器设计研究

城市中往往存在着一些关键路口,其交通通畅与否会对周围的路网的交通流起着很大的影响,需要优先保持此路口的通畅.针对以上情况,设计了基于上下游交通信息的二级模糊交通控制器来对路网进行协调控制.在此基础上,本文提出了针对交通特性改进的粒子群优化算法(TIPSO),并采用TIPSO对第一级模糊规则进行优化,实验结果表明TIPSO对模糊规则具有较好的优化效果,能够离线训练获取到比人工设定的更优的模糊规则.     

舰载火箭炮子母弹射击火力分配模型

摘 要：由于舰载火箭弹的弹道特性与普通身管炮弹有着明显的差异,传统的舰炮射击效力计算及火力分配方法不适用于舰载火箭炮。结合舰载火箭弹弹道特点,分析了其射击误差,探讨了集群目标的简化处理方法,提出了一种基于蒙特卡洛法的舰载火箭炮对岸射击最优效力射火力分配计算模型。通过举例分析表明,该方法切实可行,利用该模型可以提高射击指挥员指挥决策的科学性。     

无人作战飞机近距对抗占位策略与方法

针对无人机作战中前置追踪占位法存在导弹发射条件苛刻且目标机动时成功率锐减和离散对策占位法应用局限性较大等问题,提出一种无人作战飞机近距对抗占位策略与导引方法。该占位策略为解算无人机近距对抗占位的伪跟踪点,并设计一种三维变结构导引律,引导无人机完成近距作战占位机动。仿真结果表明,该占位策略与导引方法快速有效,满足无人机近距对抗时的战术指标要求。     

Cinematic representations of the Mexican Narco War

This essay provides an overview of the eras of Mexican cinema followed by an analysis of 10 Spanish-language narco cinematic representations, an overview of the eras of American cinema followed by an analysis of 10 English language narco cinematic representations, and a conclusion that compares and contrasts the Mexican and US narco war cinematic experience. Due to divergent national trajectories – Mexico is engulfed in narco violence and corruption while the United States is not – more differences than similarities exist between these national cinematic genres. Dark spirituality themes are also increasingly evident in more recent narco war films.     

Factors influencing the modernization of military-investment economic appraisal systems

Budgetary restrictions resulting from the present international economic crisis have tightened the need to improve efficiency in defense spending, leading to the armed forces having to undertake their duties with fewer resources. Previous reports on the subject have looked into the determining factors and effects of military spending but very few studies have analyzed the determinants for the modernization of the methodology for assessing efficiency. Thus, using a multiple regression statistical model, we have analyzed the appraisal systems in place in 28 countries to identify factors that influence the development of economic assessment of military expenditure. Our findings have revealed three factors that may favor the improvement of appraisal systems with regard to military expenditure: the quality of governance, size of the armed forces, and unemployment levels.     

Fettered Self-determination: South Sudan’s Narrowed Path to Secession

The interpretation of self-determination as a vote for secession shaped the state that South Sudan has become since the 2011 referendum. Self-determination, this paper argues, is a democratic political process in which citizens determine their preferred form of statehood and nature of governance for their country. In South Sudan, however, political actors—with international support—established conditions that reduced such complex democratic processes to narrow technical matters. Equating self-determination with secession consolidated political and military domination in a process designed to end such domination. This was done at the expense of a more inclusive, process-oriented and political interpretation of self-determination.

Capacitated selection problem

Optimizing the selection of resources to accomplish a set of tasks involves evaluating the tradeoffs between the cost of maintaining the resources necessary to accomplish the tasks and the penalty cost associated with unfinished tasks. We consider the case where resources are categorized into types, and limits (capacity) are imposed on the number of each type that can be selected. The objective is to minimize the sum of penalty costs and resource costs. This problem has several practical applications including production planning, new product design, menu selection and inventory management. We develop a branch‐and‐bound algorithm to find exact solutions to the problem. To generate bounds, we utilize a dual ascent procedure which exploits the special structure of the problem. Information from the dual and recovered primal solutions are used to select branching variables. We generate strong valid inequalities and use them to fix other variables at each branching step. Results of tests performed on reasonably sized problems are presented. © 1999 John Wiley & Sons, Inc. Naval Research Logistics 46: 19–37, 1999
