风场的科学计算可视化在导弹射击中的应用

在导弹射击时,消除风会对导弹飞行造成不利的影响,因此基于可视化分析的研究模型、流程等,利用科学计算方法直观分析优点对风的大小和方向进行分析,并采用开放图形接口对实验风场数据进行了三维图形绘制以提高导弹打击目标的精度,对实际中导弹的风场阻力研究有一定的指导意义.     

“天人合一”思想与坚持可持续发展战略

“天人合一”思想的精华在于比较系统地提出了处理人与自然关系的一系列基本观点 ,值得我们继承和发扬的有“天人一体”的整体观、人与自然和谐观、“尽乎人道 ,合乎天道”的价值观以及“知止”观等。“天人合一”思想中一些过时、错误的观点 ,我们则必须抛弃。

基于感知信息共享的C2网络特征分析

指挥控制（C2,Commandand Control）关系网络连接数的增加会增强指控节点之间的信息共享,但也会增加节点信息处理和交换负荷,如果达到一定程度,则会造成节点本身的“信息过载”从而影响C2网络性能。对此,通过研究C2网络在两种不同处理方式下的共享感知信息平均提交时间,用网络节点响应时间的均方差表征一个C2网络的共享态势感知时间的一致性,最后对两种不同结构C2网络特征参数的计算,说明了网络连接增加会导致信息提交时间的延长,但一致性会增强。     

A Question of ‘Government’ Control: Afghanistan DDR Programs Since 2001

Since the fall of the Taliban in late 2001, the Islamic Republic of Afghanistan (GIRoA), the United States, the United Nations, and the International Security Assistance Force (ISAF) have funded and led three different Disarmament, Demobilization, and Reintegration (DDR) programs. Despite a significant investment in time and treasure, all of them have failed to significantly reduce the number of insurgents or arbaki (militia). This article explores why these programs failed despite incorporating ideas from the prominent DDR schools of thought. Utilizing Stathis Kalyvas’ theory of The Logic of Violence in Civil War as a lens, this article argues that GIRoA and ISAF did not have sufficient control of territory to entice insurgents or arbaki to reconcile and/or reintegrate with the government. Further, in areas GIRoA nominally controlled in northern and western Afghanistan, regional powerbrokers who controlled these areas balked at these programs.

基于小波分形理论的快速图象编码算法

小波和分形理论应用于图象压缩领域是当今研究的前沿。提出了一种快速图象编码算法,它将加权小波变换与基于二叉树和双向链表搜索的分形编码相结合,在高压缩比、高信噪比前提下,使编码时间大大缩短。在ＰｅｎｔｉｕｍＰｒｏ２００个人机上对一２５６×２５６,８ｂｐｐ图象进行实验,编码时间仅需８秒,而图象失真很小。     

The Power of the NPT: International Norms and Ukraine's Nuclear Disarmament

ABSTRACT

There is a lingering disagreement among scholars on how the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) affects nonproliferation and disarmament outcomes. Drawing on constructivist scholarship on international norms, this article examines the extent of the NPT's effect in the case of Ukraine's nuclear disarmament. In the wake of the Soviet Union's collapse, Ukraine found itself host to the world's third largest nuclear arsenal. Despite Ukraine's initial commitment to become a non-nuclear state, it proceeded along a difficult path toward NPT accession. Most controversial and directly at odds with the NPT was Ukraine's claim to ownership of its nuclear inheritance as a successor state of the Soviet Union. This article argues that, while much domestic discourse about the fate of these nuclear weapons was embedded in the negotiation of Ukraine's new identity as a sovereign state vis-à-vis Russia and the West, the NPT played an important, structural role by outlining a separate normative space for nuclear weapons and providing the grammar of denuclearization with which Ukraine's decision makers had to grapple.     

导弹俯仰通道制导控制一体化设计

根据弹目相对运动关系及导弹系统模型,建立了导弹俯仰通道制导控制一体化模型。利用反馈线性化方法将该模型转化成为可控线性系统,基于自适应反演控制方法设计了控制器对转换后的系统进行控制。仿真结果表明,制导控制一体化设计能够有效减小导弹脱靶量,缩短导弹系统响应时间。
