夜间通风量对相变轻质房间室内热环境的影响

运用EnergyPlus软件,对含相变材料层轻质房间的室内热环境进行了模拟,分析了墙体结构、通风量等因素对相变材料轻质墙体的蓄、放热性能和室内热环境的影响。模拟结果表明:相变材料应用于轻质房间,能显著增强围护结构的热惰性,提高室内的热舒适性;同时采取夜间通风技术,可以有效地将白天蓄积的热量散至室外。相变材料布置在围护结构内侧时,室内环境的热舒适性比布置在外侧时更好。从自然通风的角度,相变材料布置于围护结构内侧时,选取换气数2.5次/h作为优化结果;相变材料布置于围护结构外侧时,选取换气数4.0次/h作为优化结果。     

舰载无人机雷达、通信侦察载荷在海战场打击效果评估中的运用

舰载无人机运用各种侦察载荷对目标进行搜索、定位,并在目标遭受打击后获取各类毁伤信息,是海战场目标打击效果评估过程中至关重要的环节。文章分别从对目标探测定位、毁伤信息获取、突防和返航等阶段,分析了舰载无人机雷达、通信侦察载荷的运用过程,讨论了雷达、通信侦察载荷在目标遭遇打击后毁伤信息获取中的具体应用,提出了雷达、通信侦察载荷在整个打击效果评估过程中使用应注意的问题。     

反海盗任务中大中口径舰炮火力应用

在反海盗任务中,大中口径舰炮武器系统可担负对海盗船进行警示或警告性射击,或者直接打击的任务。在对海盗船编队目标特性分析的基础上,以单管大口径舰炮对集群海盗船射击作为研究对象,将射击类型分为警示、警告和阻拦射击,重点分析了对集群海盗船只警告性射击方式,提出了警告性射击修正量的计算方式,最后通过实例仿真证明了该方法的适用性。     

CHILDREN IN THE SPOTLIGHT

September 11 2001 has put the spotlight on terrorism, and it has been at the apex of the international security agenda ever since. Politicians, lawmakers, scholars and others have been debating the meaning and definition of terrorism for many years. Numerous myths and misconceptions persist on this highly debated issue. With the aid of historical case studies, this article aims to demonstrate how broad a concept terrorism has become. It focuses on its subjective and value-laden interpretation and hence the difficulty of arriving at a universally acceptable definition. The author introduces the concept of ‘colonial terror’, which depicts a distinct form of state terrorism perpetrated during the colonial and post-colonial periods. Like many before her, the author concludes that the definition and meaning of terrorism lie in the eye of the beholder.

There are two ways to approach the study of terrorism. One may adopt a literal approach, taking the topic seriously, or a propagandistic approach, construing the concept of terrorism as a weapon to be exploited in the service of some system of power. In each case it is clear how to proceed. Pursuing the literal approach, we begin by determining what constitutes terrorism. We then seek instances of the phenomenon—concentrating on major examples, if we are serious—and try to determine causes and remedies. The propagandistic approach dictates a different course. We begin with the thesis that terrorism is the responsibility of some officially designated enemy. We then designate terrorist acts as ‘terrorist’ just in the cases where they can be attributed (whether plausibly or not) to the required source; otherwise they are to be ignored, suppressed or termed ‘retaliation’ or ‘self-defence’.

DAR ES SALAAM

Countries in transition often experience increased levels of crime, making their citizens vulnerable to the exploits of criminals. The lack of reliable statistics hampers the development of sound crime reduction strategies. This essay considers the value of victim surveys as additional sources of information to augment official police data. It presents the findings of such a survey undertaken in Dar es Salaam and compares them with findings obtained in similar surveys of Cape Town, Durban, Pretoria and Johannesburg. The information obtained in the survey conducted in Dar es Salaam provides valuable insights into crime rates and patterns. In comparing the results of the survey in Dar es Salaam, some interesting trends emerged around the theft of vehicle parts and vehicle theft, violent crimes, the levels of violence employed in burglaries and the use of weapons. The information gleaned from these surveys will go far in developing crime reduction strategies and measures that will be effective and appropriately targeted.
