公安边防部门刑事侦查权的取得与完善

公安边防部门取得刑事侦查权,是侦查体制改革的结果。但在边防管辖和查办案件的种类、边防海警刑事办案权的实现、边防检查站查获的刑事案件的管辖、公安边防部门侦查主体资格的完善等方面,还应继续改革．使边防部门刑事侦查机制不断完善。     

一种防空指令修正弹控制模式研究

针对防空指令修正弹的方案设计问题,探讨了一种通过选择弹丸在有控段某点停止控制而恰能完成修正指标的外弹道控制模式,推导了有控弹丸平均侧向速度和剩余飞行时间的估算公式,给出了最佳停控点的确定判据.对上述控制模式进行了仿真计算,得到不同修正条件下的侧偏修正量及攻角曲线.仿真结果表明,该控制模式具有较高的控制精度,侧偏修正最大误差不超过±2.5%,且在该模式下弹丸也可保持飞行稳定.该研究结果可用于指导防空指令修正弹的方案设计.     

A novel variable topology design for a multi-flexible ejection mechanism

The airborne missile launch mechanism often subjects to significant deformations induced by the large ejection force during high-speed actuations in missile ejection process, leading to a substantial deviation of separation parameters from designed values that threats safety of the carrier. This study proposes a novel variable topology design for launch mechanism, achieved via a Prismatic-Revolute-Revolute pair (PR-R) motion formed by the structural gap with a specific direction. It enables launch mechanism variability during missile ejection process and optimizes the ejection force given by the front and back ejection arms, and greatly optimizes the separation parameters during missile ejection. The kinetics simulation analysis is conducted under working conditions of the original ejection mechanism and the novel mechanism with variable topology design, respectively. The results show that the novel variable topology design is more befitting for the launch process in terms of system safety and controllability, effectively improving the separation posture, restraining the flexible effect of the mechanism, and fulfilling the effectiveness of the design value of multi-rigid body.

Assessing military reform in Indonesia

This article seeks to assess the magnitude of military reform in Indonesia and its impact in establishing greater levels of professionalism within the armed forces. To this end, the authors will offer some reflections on the studies of civil-military relations and military transformation for inculcating a higher degree of military professionalism; analyse to what extent the process of military reform in Indonesia has reshaped the institutional role of the armed forces; and discern three major strategic gaps in Indonesia's military reform, namely the “legal loopholes and regulation vacuum,” the “shortcomings of democratic civilian control,” and the “defence-economic gap.” This article asserts that military professionalism will grow more substantially depending on the ability of civilian elites to exercise effective control over the military and the capacity of the government to transform the military establishment keeping pace with strategic challenges and operational requirements.
