基于合作博弈的智能集群自主聚集研究

智能集群是指由大量智能体构成、采用自组织策略协作完成任务的群体。以无人车集群系统协同监视再入体着靶过程为任务背景,开展智能集群自组织策略的关键技术研究。设计了无人车集群执行再入体着靶协同监视的集群行为模式,提出了基于合作博弈的智能集群自组织策略,各智能体以实现群体聚集为“合作目标”,以降低自身能量消耗为“竞争目标”,开展博弈,基于微粒群算法规划局部路径,最终使群体系统涌现出聚集行为。仿真实验验证了设计的自主聚集策略的有效性。

Business and peace in the Niger Delta: what we know and what we need to know

The global restructuring of state–society relationships driven by neoliberal logic has not only allowed for the taming of the ‘state’, which has paradoxically accentuated its inadequacies, but has also facilitated, for better or for worse, the emergence of business – especially transnational corporations – as a major political force in global governance. Consequently, while the issues of peace and conflict have traditionally been the concern of governments, businesses are now increasingly being expected to make peace and conflict their concern. However, despite claims and counterclaims that businesses can be moneymakers and peacemakers, analyses of the relationship between business and peace remain largely embryonic. This paper seeks to contribute to this emerging business and peace debate by drawing on insights from the Niger Delta conflict to ascertain what we know and what we need to know if businesses are to become peacemakers in conflict zones in Africa.     

EU Battlegroups: High costs,no benefits

This article reviews the gloomy saga of the EU Battlegroups, focusing on four questions: Where do they come from? What do they look like? What have they been hindered by? And where do they go from here? It builds upon earlier findings in the literature and adds novel insights based on original data. In doing so, the article pays particular attention to the standby nations’ constant calculation of political and financial costs. It argues that recognizing these cost–benefit calculations allows for identifying the most crucial areas to be tackled to make the EU Battlegroups functional. In addition, the article stresses that these considerations play out in a setting wherein the Battlegroups are just one among many policy instruments available for rapid response.     

论美军“作战云”理论的制胜机理

美军"作战云"理论的制胜机理是以云计算技术作为物质基础和技术依托,以"云部署、云聚合、云攻击(防御)、云消散"体现作战过程,以"集中指挥、分布式控制和分散执行"为基本指控方式,以"跨域协同"作为作战协同的基本方式。由于该理论实现了战场信息的有效融合和共享,作战力量的动态聚能和释能,作战任务的临时赋予和即时完成以及不同领域作战能力的互补增效,因此将促使美军的武器装备、力量结构、作战方式及战场形态等发生新的重大变化。

抗磨添加剂与电弧喷涂耐磨涂层间的协同效应

研究了2种φ2mm粉芯丝材电弧喷涂Fe-Cr-Ni涂层和7Crl3涂层以及与2种典型润滑油抗磨添加剂的协同效应,并借助X光电子能谱(XPS)研究了其协同作用机理.结果表明DBP和ZDDP润滑油抗磨添加剂能明显地改善电弧喷涂Fe-Cr-Ni涂层和7Cr13涂层的抗磨性.添加剂DBP能显著地降低2种电弧喷涂涂层/GCr15摩擦副的摩擦系数,但ZDDP抗磨添加u剂的减摩效果不太显著.在含DBP和ZDDP添加剂油润滑条件下,涂层磨痕表面形成了摩擦化学反应膜.
