新疆公安边防维稳预警情报收集中的问题与对策

新疆维稳形势严峻,预警是维护社会稳定的重要途径。情报收集是成功预警的前提和基础。当前的新疆维稳预警情报收集工作还存在收集主体素质不高,群众优势未能充分发挥,缺乏有效交流与合作等问题。为此。必须加强情报队伍建设,构筑人民防线,完善协作机制,加强情报交流,以改进情报收集工作。     

1902-1911年普通中小学堂图画课程改革述评

普通中小学堂图画课程是中国近代化的产物,从1902年＂壬寅学制＂在政策层面上确立了图画课程的地位开始一直到1911年,普通中小学堂图画课程进行了多次改革。这些改革开启了学校制度下中小学美术教育发展的进程,形成了重＂技＂的教育指导思想影响下的普通中小学堂图画课程,体现了浓厚的日本学校图画课程色彩,编纂了我国第一批普通中小学图画课程教科书。虽然受时代条件所限,这一时期课程实施效果不尽如人意,但却反映了近代中国美术教育学人在这一时期的艰难探索和追求。     

基于系统动力学的工程项目目标控制

针对工程项目目标控制问题,通过德尔菲法确定工程项目目标控制的主要影响因素,基于系统动力学反馈与仿真分析理论建立了工程项目目标控制系统动力学模型。采用专家打分法确定参数,利用Vensim软件对模型进行模拟演化和算例分析,讨论不同策略和策略组合的工程项目目标控制效果,最终得到基于算例工程的理想方案为0时增加人工8人,0时加班1 d,管理费水平为3。采用该方案,该工程的完工时间提前47.2%,质量下降2.0%,费用上升6.7%。通过不同策略和策略组合的效果比较,得出结论：加班宜尽量少用,尤其要避免连续加班;尽量避免无效管理费用支出,但对于可以带来管理水平提高的管理费用支出宜适量增加;增加人工越早越好。     

Terrorism,crime and public spending: Panel VAR evidence from europe

Within a panel VAR framework and utilizing generalized impulse response and forecast error variance decomposition analysis, we explore the dynamic effects of terrorism and crime on public order and safety spending across European countries during the period 1994–2006. Our findings show that a ‘shock’ in terrorism and/or in crime, significantly increases the subsequent trajectory of public order and safety spending. As a by-product, we find that public spending is ineffective in reducing observed crime or terrorism.     

Command and Control of India's Nuclear Forces

The Indian government has not made a public comment about the status of its nuclear weapon program since approving a nuclear doctrine in 2003. However, there is now enough information in the public domain to determine that the command-and-control system for the nuclear program has steadily matured in accordance with the intent of the approved nuclear doctrine. The Indian government has successfully mitigated many of the issues that plague the conventional military. The result is a basic command-and-control system that is focused only on the delivery, if ordered by the prime minister, of nuclear weapons. The system is not as robust as those of the United States and Russia, but is in place and ready as new Indian nuclear weapons enter into operation. The command-and-control system is developing to meet India's needs and political compulsions, but not necessarily as part of a more assertive nuclear policy.     

孙子“奇正”思想在武警部队反恐怖行动中的运用

我国现存最早的兵书《孙子兵法》,蕴含着许多克敌制胜的谋略,其中“奇正”思想在孙武战术思想体系中占有重要的位置。研究孙子“奇正”思想,并借鉴运用于武警部队反恐怖行动,对有效处置恐怖事件有着重要的现实意义。     

翼伞精确空投系统归航轨迹规划与控制

翼伞归航轨迹规划与控制问题是翼伞系统在一定初始状态下,利用自身可操作性,完成从初始位置到目标位置的转移问题。针对翼伞空投系统不同归航要求,规划出满足精度要求为圆径概率误差（ CEP ）小于40m的归航轨迹并经过一定量的控制完成翼伞空投系统精确空投任务。首先建立翼伞系统状态空间六自由度模型,并在此基础上提出系统简化稳态模型,通过最优控制方法,规划出满足空投要求的最优归航轨迹后对翼伞进行不断控制直至目标点。最后通过Matlab仿真试验,绘出翼伞系统归航轨迹图与控制变化图。     

On the continued acceleration of bomb casing fragments following casing fracture

It has been said that, once a bomb casing has fractured, “detonation gases will then stream around the fragments or bypass them, and the acceleration process stops there.” However, while apparently copious gas flow through casing fractures indicates some pressure release, it is also an indication of significant gas drive pressure, post casing fracture. This paper shows two approaches to the problem of calculating the actual loss of drive. One presents first-order analytical calculations, in cylindrical geometry, of pressure loss to the inside surface of a fractured casing. The second shows the modelling of a selected example in the CTH code. Both approaches reveal that gas escape, while occurring at its own sound-speed relative to the adjacent casing fragments, has to compete with rapid radial expansion of the casing. Together with some historic experiments now publicly available, our calculations indicate that post-fracture casing fragment acceleration is, for most systems, unlikely to be reduced significantly.
