军警体育教学中认知结构与动作技能的形成

军警动作技能是军警部队官兵所必备的素质之一,也是其具备野外作战能力的基础。但是,有些身体素质良好的军警人员,掌握和发挥动作技能的水平却很低。在教学中要从全新的角度对军警人员获得动作技能的过程进行认知分析,以促进认知结构与动作技能的形成。

Transient analysis of Markov models of fault‐tolerant systems with deferred repair using split regenerative randomization

The (standard) randomization method is an attractive alternative for the transient analysis of continuous time Markov models. The main advantages of the method are numerical stability, well‐controlled computation error, and ability to specify the computation error in advance. However, the fact that the method can be computationally very expensive limits its applicability. In this paper, we develop a new method called split regenerative randomization, which, having the same good properties as standard randomization, can be significantly more efficient. The method covers reliability‐like models with a particular but quite general structure and requires the selection of a subset of states and a regenerative state satisfying some conditions. For a class of continuous time Markov models, model class C₂, including typical failure/repair reliability‐like models with exponential failure and repair time distributions and deferred repair, natural selections are available for both the subset of states and the regenerative state and, for those natural selections, theoretical results are available assessing the efficiency of the method in terms of “visible” model characteristics. Those results can be used to anticipate when the method can be expected to be competitive. We illustrate the application of the method using a large class C₂ model and show that for models in that class the method can indeed be significantly more efficient than previously available randomization‐based methods. © 2006 Wiley Periodicals, Inc.

面向决策的一体化建模方法及其在兵力筹划中的应用

在对军事决策问题的主要特点进行分析的基础上,提出从军事概念模型到数学模型再到定性推理模型的一体化建模思想.以空军航空兵遂行直接航空火力支援任务为想定背景,根据EATI模板,利用基于UML的Rose工具依次对想定任务的实体、任务、交互等进行分析;对于兵力筹划中的结构化问题建立了机会约束多目标规划数学模型;对于非结构化问题则构造了推理机,推理机体现了定量与定性相结合的决策分析思想.最后,以一个实例验证文章思路的可行性.     

基于"联合指数"的联合作战编组集团能力量化分析

随着科学技术的发展,以信息技术作为联结手段、由各军兵种部队参加的一种新的作战方式———联合作战,已经正式登上人类战争的舞台.而对于联合作战编组集团的作战力量的量化分析,是摆在联合作战模拟人员面前的一个重要而紧迫的任务.文中以“联合指数”方法为基础,就联合作战编组集团能力量化问题特别是对不同武器装备作战单元的能力量化进行了探讨.     

Boko Haram terrorism in Nigeria

Since the July 2009 Boko Haram terrorist outburst in Nigeria, there have been increasing questions on the phenomenon in the country. There has not been any substantial analysis on the emergence of the Boko Haram group and its terrorist activities in Nigeria as the out-rage continues. This study is advanced to explain the phenomenon of Boko Haram terrorism in Nigeria. It employs the levels of analysis framework popular in the field of international relations to explain the terrorism at three major levels: individual, state and international. The study relies on dependable news reports, which include interviews with key actors relevant to the subject matter, and finds that Boko Haram terrorism has its roots in the ideology and motivations of its founder and members, the failures and deficiencies of the Nigerian state, and the modern trend of religious terrorism in the international system.     

一种针对HIGHT的改进差分故障的分析

为评估HIGHT轻型分组密码抗故障攻击能力,基于单字节故障模型,提出一种改进的HIGHT故障攻击方法．首先在HIGHT最后1轮注入单字节故障恢复SK124和SK1262个轮密钥,然后增加故障注入深度,在HIGHT倒数第5轮注入单字节故障恢复HIGHT另外10个轮密钥,从而恢复HIGHT的全部主密钥．实验结果表明：仅需22次故障注入即可恢复HIGHT全部128位主密钥,优于现有故障攻击方法所需的32次故障注入．
