模糊数据的编码压缩

建立在普通集合之上的传统的数据压缩方法不能胜任模糊领域中的问题。因此,有必要从模糊集合理论出发,导出模糊概率的概念和模糊信息,赋予数据压缩理论和技术新的活力。本文试图从模糊理论的角度,借助于广义信息论,探讨模糊信息压缩的方法和意义。     

Rossellini,Pontecorvo, and the neorealist cinema of insurgency

This article examines the tradition of Italian neorealism and the importance it has for films depicting guerrilla insurgencies. It looks in particular at the two films by Roberto Rossellini Rome Open City and Paisa as well as the later film by Nanni Loy Four Days in Naples. It then proceeds to locate Gillo Pontecorvo's iconic film The Battle of Algiers within this neorealist tradition and examines the degree to which the director succeeded in continuing the basic traditions of neorealism into the context of the Algerian war of Independence. The article concludes that while this film remains of great interest it should be situated in the period when it was produced and is in many ways radically disconnected from many insurgent movements of the present day.     

National security,military spending and the business cycle

This paper develops a Dynamic Stochastic General Equilibrium model where national security is an argument in the agent’s utility function and the government chooses optimally the level of military spending to maximize social welfare. National defense depends on military expenditure and on the strategic environment reflecting a potential hostile external threat. We use aggregate data on consumption, investment, and military spending for the US economy to estimate the parameters of the model. Estimation results suggest that consumption and national defense are complements and that military spending variability is mainly explained by external threat shocks although it also depends on the macroeconomic conditions. We compute impulse response functions of the main macroeconomic variables to several shocks: a total factor productivity shock, a defense technology shock, and a strategic environment shock. Surprisingly, we find that the optimal response to an increase in the external threat (a worsening in the strategic environment) will rise output by reducing consumption and increasing investment.     

COIN fights: A response to Etzioni

Etzioni both exaggerates and minimizes the influence of my book Learning to Eat Soup with a Knife on different components of US military doctrine, mischaracterizes my treatment of the Malayan Emergency, and unfairly denigrates the successes of counterinsurgency in Iraq from 2007 to 2011 while misattributing the reasons for its failures in both Iraq and Afghanistan.     

舰炮火力系统智能结构分析

遵从“智能增加,精度降低”(IPDI)原则,将舰炮火力系统(含雷达、C~3I、舰炮等系统)的智能结构分为概念、协调、执行3级,并着重分析采用广义信息熵作为各级统一评价标准的可能性。最后,还简要提出了新型舰炮火力系统智能化发展的方向。     

一般自我效能感与社会支持对中学生主观幸福感的影响

目的：探讨一般自我效能感、社会支持对中学生主观幸福感的影响,为提高中学生的主观幸福感提供理论依据。方法：采用一般自我效能感（GSES）、领悟社会支持（PASS）问卷和总体幸福感（PGWB）量表,对新疆地区部分中学的1000名中学生进行调查。结果：①不同性别中学生在一般自我效能感、其它支持和社会总支持存在显著差异（P〈0.05）;不同家庭类型中学生在领悟社会支持及各因子、忧郁或愉快的心境以及对情感和行为的控制方面存在显著差异（P〈0.05）。②总体幸福感中的对健康的担心这一因子与社会支持和各因子（其他支持除外）及一般自我效能感呈显著负相关（P〈0.05）,而其他各因子与社会支持各因子及自我效能感呈显著正相关（P〈0.05）。③一般自我效能感、家庭支持和朋友支持对中学生主观幸福感具有显著地预测作用（P〈0.05）。结论：中学生的性别、家庭类型在一般自我效能感、社会支持和主观幸福感方面表现出差异性,且中学生的一般自我效能感、社会支持与中学生主观幸福感之间存在相互关系。

锥壳稳定方程的一般解

在本文中,用应力函数和中面法向位移表示的锥壳稳定方程被变化成为一对无奇异性的简化方程,然后得出了方程的幂级数形式的一般解。计算结果与已有的实验结果符合良好。计算分析了８种边界情况下边界条件对静水外压临界载荷的影响及解的收敛性。     

人手操作的联体计算

机器人的一个重要理论问题是如何控制机械手以获得所需要的运动。本文将人手操作的基本运动,抽象为具有七个构件而有九个自由度的刚体系统,严格地分析了这些运动,并根据实际情况考虑到各构件的重力、控制力和摩擦阻力,因此能完成人手操作的多种功能。而为了便于在计算机上实施运算利用Kane方程建立了以广义坐标表达的运动微分方程,这可作为分析机械手运动的理论依据。     

The contexts of strategy as a guide for defense planning in the Philippines

Efforts toward developing an independent and credible Philippine defense policy were revived when Benigno Simeon C. Aquino III was elected President of the Philippines in 2010. President Aquino renewed the military modernization program in 2012 and emphasized the necessity of a “minimum credible defense posture.” Given the modernization efforts of the government, this article aims to contribute to the development of the concept of minimum credible defense posture by exploring how theory contributes to defense planning. It argues that the contexts of strategy are useful in planning for national defense because these contexts can provide a conceptual framework for defense planners. It proceeds in three parts: the opening section reviews the literature on defense planning; the second surveys the context of developing strategies as discussed in the General Theory of Strategy; and the last provides a definition of minimum credible defense and applies the context of developing strategies to the case of the Philippines.
