Maintaining peace in a neighbourhood torn by separatism: the case of Satun province in southern Thailand

While separatist-related conflict has re-emerged in southern Thailand, there is one predominantly Muslim border province that has remained outside of the conflict. Satun province has been conspicuously unaffected by the Malay-Muslim separatist movement, despite its shared history and ethnic origins with the conflict-affected provinces. In contrast to Pattani, Yala, and Narathiwat, the process of state penetration in Satun was gradual and comparatively less coercive, leading to relative stability and encouraging political and economic integration. This comparative study analyzes the history of cooperative state–minority relations and political stability in Satun province, and draws important lessons directly applicable to the unrest in neighbouring provinces.     

基于区间数理论的空战目标威胁评估

针对空战目标威胁评估问题,提出了一种新的基于区间数理论的评估方法。在分析了现有的目标威胁评估方法中距离威胁模型存在不足的基础上,提出了改进的距离威胁模型。给出了区间数特征向量法求解威胁指标权重的计算步骤,建立了基于区间数理论的空战目标威胁评估的数学模型。最后给出了仿真算例,仿真结果表明该方法是合理和有效的。     

空投设备气囊缓冲系统的缓冲特性分析与匹配方法

采用解析分析法,根据排气口流量方程和载荷运动方程建立了无量纲的空投设备气囊缓冲过程数学模型,并根据此模型构造了气囊的匹配设计图。讨论了排气口面积、气囊高度、着陆初速度、载荷质量、气囊底面积及排气口开启压力等参数对气囊缓冲性能的影响,提出了空投设备气囊缓冲系统的参数匹配设计方法,为空投设备气囊缓冲系统的匹配设计提供了技术支持。
