Kinematic planning of slew manoeuvres after actuator failure for low-cost satellites

A kinematic scheme is presented which allows for planning attitude manoeuvres of satellites after actuator failure. The scheme relies on the identification of admissible rotation axes around which the control system can deliver torque components in spite of the failure. Two techniques discussed in the literature, based on a single rotation that either minimizes the angular displacement from a given target attitude or aims a sensor exactly along a prescribed direction, are compared with a new technique based on a two-step approach, which allows for achieving any prescribed attitude by means of a sequence of two feasible rotations. Dynamic simulation is used for analysing potential capabilities and limits of the considered kinematic approaches to manoeuvre planning of under-actuated satellites.

六自由度动态模拟环境试验系统

六自由度动态模拟环境试验是考核车辆、舰船等运输工具在复线路面谱或海浪谱的运动条件和不同气候环境条件同时作用下的性能可靠性和行驶安全性及其使用寿命的重要模拟试验方法。本文详细介绍了为满足这一试验而研发的六自由度动态模拟环境试验系统。     

共同沟工艺及给排水设计的几点探讨

我国在工程设计中越来越多地采用共同沟工艺,但尚未有国家层面的标准化的相关规范,因此现阶段的工艺设计在给排水方面需参照国外及国内已兴建的共同管沟,尽可能全面地考虑工程设计中会碰到的问题,由此提出一些设计理念。     

Occupational Safety Culture Index (OSCI)——measuring the community and employees awareness,attitude and knowledge towards workplace safety and health in Hong Kong SAR

Promoting occupational safety and health in Hong Kong,Special Administrative Region of China is an important and ongoing mission. As the major organization with statutory responsibilities,the Occupational Safety and Health Council understand the importance to strengthen and cultivate our safety culture. It is widely believed that numbers of occupational related diseases and injuries could be prevented with the improvement of the awareness and attitudes of the employees and the public. Therefore,a comprehensive and in-depth study to monitor the occupational health and safety level and status of the community and working population is needed. Objectives: Our Council has developed the Occupational Safety Culture Index ( OSCI) to measure the current level of community and workplace safety and health awareness,knowledge and attitude. Benchmarking measures of the key safety performance indicators are to be derived thereof. Methods: A territory-wide random telephone survey was conducted to assess the community and employees’awareness,attitude and knowledge in 2008. A structured questionnaire was designed with the content validity and reliability assessed before the survey administration. A series of quality control approaches were also applied to assure the quality of the fieldwork and the reliability of the data. Results: 1,531 eligible participants’data were collected and computed into 2 types of composite indices,Occupational Safety Culture Index ( Community) ( OSCIC) and Occupational Safety Culture Index (Workplace) (OSCIW) . With the maximum score of index at 100,the overall score of OSCIC is 66. 9 and the OSCIW is 61. 3 in Hong Kong. Achievements: OSCI served as an effective management tool to measure the safety culture in Hong Kong. With a representative sample and high quality study control and validated assessment approaches,the OSCI and the sub-indices are reliable indicators to assess the effectiveness of safety culture enhancement strategy and the OSH intervention measures.     

组织氛围对建筑工人不安全行为的影响机理及实证研究

为了研究组织氛围对建筑工人不安全行为的影响,从班组级安全氛围、班组级安全教育和项目级安全氛围三个层面测量组织氛围,基于组织氛围与安全态度、不安全动机及安全能力之间的关系,构建建筑工人不安全行为发生的机理。通过23个项目267份有效问卷收集数据,采用结构方程模型（SEM）进行验证,采用决策试验和评价实验室（DEMATEL）进一步计算和分析各潜变量之间的影响度和被影响度。研究结果表明:班组级安全氛围对安全态度、班组级安全教育对安全态度、安全能力对安全态度、安全态度对安全动机的影响显著;安全动机和安全能力对不安全行为的影响显著;班组级安全氛围、班组级安全教育和项目级安全氛围之间相互关系显著;班组级安全氛围、班组级安全教育和项目级安全教育是典型的原因影响因素,通过安全态度共同影响不安全行为。根据研究结果,提出应对措施,可为安全管理工作提供理论指导。
