Structural reliability optimization using an efficient safety index calculation procedure

The objective of this paper is to conduct reliability-based structural optimization in a multidisciplinary environment. An efficient reliability analysis is developed by expanding the limit functions in terms of intermediate design variables. The design constraints are approximated using multivariate splines in searching for the optimum. The reduction in computational cost realized in safety index calculation and optimization are demonstrated through several structural problems. This paper presents safety index computation, analytical sensitivity analysis of reliability constraints and optimization using truss, frame and plate examples.

Insulating safety analysis of the hot-line sweeping robot

This paper presents a method of calculating the insulating safety distances for hot-line working robots at high voltage when dielectric is adulterated with conducts. Also, finite element method is adopted to calculate the electric field strength to find whether it is beyond the critical. The above methods have been applied to analyze the insulating safety of the robot for hot-line sweeping post insulators in a 220 KV substation. They have also been testified by experimentations.

亟待理顺我国的煤炭安全生产管理体制

我国煤炭生产安全形势严峻,需要政府加强安全生产管理。多重机构的管理模式是否就是加强了安全管理值得探讨。从调研中发现,现行分散的行业管理体制结构分解了煤矿的安全生产责任,鉴于煤矿安全生产的技术性很强,精简管理机构、强化职能责任是煤矿安全管理改革的目标,重视管理科学的实践应用,理顺煤炭生产安全管理体制迫在眉睫。

Establishing a System for Food Recalls to Protect Food Quality and Safety in China

There are no explicit laws concerning food recalls in China; moreover, some related regulations have weaknesses. China should first create a system of laws and regulations governing food recalls, establish a system to recall defective food, and strengthen administrative and legal remedial mechanisms related to consumer rights.     

可燃气体冷冻储存安全性分析

根据烃类和其它可燃气体液化储存的特性，比较了气体液化冷冻储存和压力液化储存在设备出现泄漏时的可燃气体释放量、释放速率和扩散范围指出，可燃气体液化冷冻储存与压力液化储存相比。储存压力低，即使出现泄漏，因其泄漏量少。泄漏速率低，扩散范围小，因而可燃气体液化冷冻储存比压力液化储存更为安全。     

改进的BP神经网络在大坝安全监控中的应用

针对经典BP神经网络运行中存在的缺陷，提出了改进的BP神经网络，不仅解决了经典BP网络易陷入局部最小的弊端，而且应用的0.618分割选取法能使网络快速找到较优隐含层节点数，初始权值的自相关修正进一步提高了网络的稳定性。实际应用证明，改进的BP神经网络有效提高了网络质量，适合大型网络的构建与训练。
