基于视频监控的人的异常行为系统设计

"视频监控"是一种可实现夜间检测的视频监控系统,普遍用于沿街商铺、仓库、郊区独户别墅以及小区等场所。传统的视频监控对摄像头的要求较高,并且需要多人值守,对人力、财力的要求较高。针对传统视频监控存在的不足,设计了一种智能检测系统,能实现对非法入侵、物品盗移等异常状况的实时检测和及时报警,还针对夜间图像的特点设计增强算法,使普通摄像头可实现夜间监控,大大降低了视频监控的应用成本并提高了监控效率。

技术成熟度多维评估模型研究

技术成熟度直接关系到武器装备的研制和应用。针对技术成熟度评估存在过度依赖专家智慧、操作周期长、费用高;指标单一、可信度缺乏;数据难以获取、评价方法难度较大等问题,研究了技术发展与技术对应文献关系,提出了基于技术分解结构构建技术成熟度多维评估模型,分析了基于S曲线知识图谱划分技术成熟度等级,并以航母电磁弹射器技术为例进行模型验证。研究表明,技术成熟度多维评估模型具有客观、简便、费用低、易操作等特点,可以与TRL互为补充。     

Portfolio analysis for defense: taking account of networking

To manage their assets at an enterprise level, defense organizations have turned to portfolio theory for the planning, analysis and management of their military forces and materiel. Despite being well established in the commercial sector, the application of portfolio approaches in defense is problematic. The vexatious question for defense of how to define and measure benefits arising is complicated by the increased utility and effectiveness achieved through networking of military forces and the equipment they use. The authors discuss the challenges for defense in using a portfolio approach and propose a conceptual model for dealing with the effects arising from networking with information and communications technologies.

An alliance between Cyprus and Greece: assessing its partners’ relative security contribution

The issue that this paper tackles is the assessment of the relative security benefits that Cyprus and Greece derive in the context of their cooperation on defence matters. This form of cooperation, known as the ‘Integrated Defence Space Doctrine’, aims at defending their interests in the Aegean Sea and the broader East Mediterranean theatre. The paper relies heavily on earlier research on this topic, which deals with the Greek–Cypriot alliance facing an arms race against Turkey, and uses a coefficient especially designed to assess the optimal levels of security and the associated defence expenditure of the two allies. A comparison of the relative security coefficient values for the two allies suggests that the security benefit that Greece derives thanks to its alliance with Cyprus exceeds the corresponding Cypriot benefit by far. Given the importance assigned to human resources by this index, in conjunction with the demographic problems of Greece, this conclusion justifies the recent Greek defence policy revision, emphasizing quality, capital equipment and flexibility of forces. This revision aims at satisfying the security requirements of the alliance and the increasing demands of an arms race against Turkey.     

Evasion costs and the theory Of conscription

This paper examines the trade and military relationship between two countries which have a common military enemy. The paper explains how the former two countries, which are military allies and trading partners, share the burden of defence against the third country. It demonstrates how the defence production of a country may hurt its ally because the latter country's terms of trade can be deteriorated. Whether or not a smaller ally spends less on defence is analyzed. Also analyzed is the effects of the reactions of the enemy country on the trade between the two allies and their welfare.     

SLOWING DOWN TO KEEP THE LEAD IN MILITARY TECHNOLOGY

We develop a model of military technology competition among states. States can choose to introduce new military technology, mimic rivals’ level of technology, or withdraw from the contest. States can choose to implement any level of technology within their current feasible technologies. We find that states with significant technological leads should sometimes withhold new technologies, only strategically releasing them to trump rivals’ efforts. We develop the model by refining Admiral Jackie Fisher’s roughly articulated concept of ‘plunging’. We then use this refined argument to reanalyze the case of naval rivalries among European powers between the Crimean War and the First World War. Finally, we conclude by discussing the model’s implications for current US military force structure planning.
