When Peacekeepers Fail Thousands are Going to Die. The ETO in Rwanda: a Story of Deception

This study develops the concepts of fourth generation operations and the associated principles. First, the concept of fourth generation operations is introduced and defined. Fourth generation operations are the evolution and extension of third and fourth generation warfare based on a change of tactics, technology, and combatants. These operations are currently ongoing in Afghanistan and Iraq, and with the global war on terrorism. Based on the framework of US joint doctrine, the supporting principles of fourth generation operations are developed. This requires the introduction of the principle of Population Perception.     

Colonial violence and its ‘Small Wars’: fighting the Kuki ‘guerillas’ during the Great War in Northeast India, 1917–1919

ABSTRACT

This paper concerns the lesser known British counterinsurgency (COIN) operations in Northeast frontier of India during the First World War. Officially known as the ‘Kuki Operations’, it was considered as part of the Great War. Carried out in isolation from press and public, and shelved in colonial archives, the event remained invisible until today. Yet, it registers a critical case of colonial COIN doctrine where the ‘moral effect’ doctrine was employed without being questioned. It unleashed enormous amount of organized violence, ranging from shoot at sight to indiscriminate burning of villages, wholesale destruction of property and livestock, prevention of cultivation and rebuilding of villages, forced mass displacement in jungles or in ‘concentration camps’, and collective punishment (communal penal labour and payment of compensation) after the war. This paper argues that the theory of ‘minimum force’ and the practicability of the ‘moral effect’ doctrine as applied by the Empire, sit oddly with each other at the frontier, where violence was seen both as a natural and moral orders. Violence as an ‘imperatively necessary’ method to bring order in a disorderly frontier, in the opinion of colonial state, informs and registers Northeast India as geography of violence.     

India's Pursuit Of Ballistic Missile Defense

This article analyzes India's efforts to deploy a Ballistic Missile Program (BMD). The article has three objectives. First, it argues that scientific-bureaucratic factors and India's incapacity to deter Pakistan's use of terrorist proxies have driven its quest for BMD. Second, the article also evaluates the current state of India's two-tiered missile defense shield. In spite of various claims on the part of India's defense science establishment, the paper estimates that India still lacks a deployable BMD system and is still far from developing an effective strategy of deterrence-through-denial. Third, the article analyzes the implications of the development of India's BMD system for nuclear stability in South Asia. The article shows how India's BMD capacities, however limited, have indirectly exacerbated the security concerns of India's regional rival, Pakistan.     

基于ANSYS的油罐拱顶稳定性分析

针对加肋拱顶稳定性十分复杂的问题,基于ANSYS建立了加肋拱顶油罐的三维有限元模型,对加肋拱顶的结构稳定性进行了数值模拟。对加肋拱顶在外压作用下的线性与非线性临界屈曲载荷进行了对比分析,利用弧长法获得了拱顶在加肋情况下径向、环向、轴向的载荷-位移曲线。结果表明:数值模拟的加肋拱顶屈曲方向和屈曲区域与实际失稳结果相一致,可以为加肋拱顶设计和稳定性分析提供一定参考。     

基于复杂网络的联合作战指挥网络拓扑结构

以复杂网络理论为基础,对联合作战指挥网络进行拓扑抽象,将指挥机构视为网络的节点,将指挥关系视为网络的边,构建了传统树状指挥网络模型、增加同级边互联的改进型指挥网络模型和不同层级边互联的交叉互联型指挥网络模型。并分析了三种网络的网络特性,以网络化效能系数（ CNE）作为度量指标,对三种网络抗毁性进行了比对分析,指出了未来联合作战指挥网络体系需要具备的特征,对探索信息化条件下高效的联合作战指挥进行了有益的探索。     

边坡稳定性理论及其局限性

边坡分析理论经过近几十年的发展,基本形成了完善的体系。较为典型的有 极限平衡法,极限分析法,有限元法等。对各种分析方法做了简要的回顾与评述。基于极限 平衡原理发展的各种分析方法,大多需要做许多假设,同时对岩质边坡又不能很好地考虑其 断层节理特征。有限元强度折减法,是近年来发展起来的一种分析方法,与极限平衡法相比 不需要任何假设,可以求得任意形状边坡的临界滑移面及其对应的安全系数,同时可以反映 边坡失稳及塑性区的发展过程,为岩土体边坡分析开辟了新的途径。
