War,vagueness and hybrid war

It has frequently been observed in the literature on hybrid wars that there is a grey zone between peace and war, and that hybrid wars are conflicts which are not clear cases of war. In this paper, I attempt to illuminate this grey zone and the concept and nature of war from the philosophical discussions of vagueness and institutional facts. Vague terms are characterized by the fact that there is no non-arbitrary boundary between entities which lie in their extension, and entities which do not lie in their extension. I apply a theory of vagueness to notions such as “war” and “peace” and go on to suggest that the exact boundary for what counts as a war or not is arbitrary. However, the context in which the conflict occurs determines a range of possible locations for this boundary. The most important contextual parameter is in this respect how the parties to the conflict themselves conceptualize the conflict. I suggest that this can in various ways help us understand grey-zone conflicts.     

Verification and validation of detonation modeling

The mathematical model used to describe the detonation multi-physics phenomenon is usually given by highly coupled nonlinear partial differential equations. Numerical simulation and the computer aided engineering (CAE) technique has become the third pillar of detonation research, along with theory and experiment, due to the detonation phenomenon is difficult to explain by the theoretical analysis, and the cost required to accredit the reliability of detonation products is very high, even some physical experiments of detonation are impossible. The numerical simulation technique can solve these complex problems in the real situation repeatedly and reduce the design cost and time stunningly. But the reliability of numerical simulation software and the serviceability of the computational result seriously hinders the extension, application and the self-restoration of the simulation software, restricts its independently innovational ability. This article deals with the physical modeling, numerical simulation, and software development of detonation in a unified way. Verification and validation and uncertainty quantification (V&V&UQ) is an important approach in ensuring the credibility of the modeling and simulation of detonation. V&V of detonation is based on our independently developed detonation multi-physics software-LAD2D. We propose the verification method based on mathematical theory and program function as well as availability of its program execution. Validation is executed by comparing with the experiment data. At last, we propose the future prospect of numerical simulation software and the CAE technique, and we also pay attention to the research direction of V&V&UQ.     

法学教学中案例教学法的反思与探索

法学是一门理论性与实践性都很强的学科,法学教育的目的在于为社会培养应用型、实践型的法律人才。传统上重理论轻实践的教学模式已无法满足这一要求,而科学合理地引入案例教学是弥补传统模式不足的有效手段。     

现役制边防检查行政执法问题浅析

现役制出入境边防检查体制与建国初期的国际国内形势相适应,并在当时的历史环境下发挥了重要作用。在全球信息、经济、交流一体化和改革开放的大环境下,面对建设社会主义法治国家的要求,现役制也暴露出诸多不足。从现役制这一特点出发,分析现役制出入境边防检查行政执法的一些基本法律问题,为执法规范化建设和构建中国特色边防检查管理体系与制度作了一些探讨。     

谈比例原则在规范消防行政执法裁量权中的适用

比例原则着眼于法益的均衡,要求行政主体在实现行政管理目标的同时,注意维护相对人的权益。作为行政法上控制自由裁量权的一项重要原则,在阐述了比例原则内涵与价值的基础上,针对消防行政执法自由裁量权行使的错位与失范,提出用比例原则进行规范与控制。     

增强忧患意识常怀忧党之心——学习党的十七届四中全会精神

党的十七届四中全会指出：“全党必须居安思危,增强忧患意识,常怀忧党之心,恪尽兴党之责。”增强忧患意识,常怀忧党之心,要从十七届四中全会召开的特殊背景来帮助理解,要从十七届四中全会对党的建设形势的分析来加深理解,要从十七届四中全会建设“学习型政党”战略任务的提出来着重理解。

磁隐身坦克的实验设计及性能检测

通过模拟实验,研究了磁隐身坦克的核心元件——同轴密绕消磁线圈的使用性能。实验室对其消磁效应的数据分析表明:同轴密绕消磁线圈能够消除坦克周围因被地磁场磁化而产生的磁场标志,其中近轴区域的消磁效果更为明显;如果在消磁线圈中通入反向电流,消磁物体的磁场反而会增强,呈缓慢磁化的趋势,这与电磁场理论相符。本实验设计的消磁线圈属于一种新功能的电磁装甲,能提高坦克在电磁战中的生存能力。     

Consecutive k‐within‐m‐out‐of‐n:F system with exchangeable components

As a generalization of k‐out‐of‐n:F and consecutive k‐out‐of‐n:F systems, the consecutive k‐within‐m‐out‐of‐n:F system consists of n linearly ordered components such that the system fails iff there are m consecutive components which include among them at least k failed components. In this article, the reliability properties of consecutive k‐within‐m‐out‐of‐n:F systems with exchangeable components are studied. The bounds and approximations for the survival function are provided. A Monte Carlo estimator of system signature is obtained and used to approximate survival function. The results are illustrated and numerics are provided for an exchangeable multivariate Pareto distribution. © 2009 Wiley Periodicals, Inc. Naval Research Logistics 2009
