Reliability-based calibration of fatigue design guidelines for ship structures

A simple reliability-based framework is applied to calibrate a new set of fatigue design guidelines. This new guideline considers two different approaches for the assessment of both loads, stresses and local stress raising effects, and partial safety factors must be given for any combination of these approaches. For the calibration, the lognormal reliability format is adopted because the hereby-derived partial safety factors can be combined arbitrarily. This means that with a few basic partial safety factors, the combination of partial safety factors to be applied together with any combination of calculation approaches can be determined easily. In the present paper both the adopted reliability format, the applied modeling of uncertainties and the selected target safety index are explained. Based on this, a new guideline is calibrated and the derived partial safety factors are presented. Finally, the new guideline is applied through a numerical example in order to show the applicability of the calibrated partial safety factors, and satisfactory results are found.     

Mobile phone use while driving: public opinions on restrictions

This paper reviews two road-user surveys on the use of mobile phones on the road in Finland where the mobile phone ownership rate is highest in the world (70% in August 2000). From 1998 to 1999 the proportion of drivers that chose to use a mobile phone while driving rose from 56% to 68%, while the proportion of phone using drivers who experienced dangerous situations due to phone use rose from 44% to 50%. The proportion of drivers who used their phones in some way to benefit safety on the road remained at about 55%. The youngest, novice drivers had the highest level of phone usage of all age categories. Over 48% of the interviewees believed that the government should ban the use of hand-held mobile phones while driving, and another 27% believed that all types of mobile phone use should be banned while driving. Those drivers who used their phones the most each day were more likely to want some form of restrictions, than those who had lower usage. This is a strong message to the elected lawmakers and raises the problem of exactly how regulatory bodies would go about controlling the future growth of new driver support and non-driving related communication devices in road vehicles. It was concluded that legislating for hands-free use only would be a reasonable course of action. Mandating that the current generation of equipment should be optimized for hands-free use should result in future generations of in-vehicle equipment also being optimized for hands-free use as a minimum criterion.

网络数据融合技术在MITS中的应用研究

探讨了基于传感器网络的数据融合技术在海事智能交通系统(MITS)中的应用问题,为该领域的进一步研究提供一些有价值的思路和见解。基于目前研究遇到的困境,提出将MITS抽象成一个无线传感器网络(WSN),从而可在WSN环境下引入数据融合技术来研究海事智能交通系统中的各种信息处理问题,如船舶的定位与导航以及避碰等;紧接着,总结了现有定位、导航、避碰和船舶安全管理技术研究的现状并分析了存在的主要问题;针对基于GPS的MITS存在的种种弊端,结合各国卫星定位导航系统的建设现状,提出利用MITS内其它元素的信息和多源信息融合技术来实现船舶的相对定位和导航这一新思路;最后,从网络数据融合技术角度出发,具体指出了MITS网络融合系统构建时所必须考虑的一些基本问题,并给出该融合系统的一般性框架。     

浅述施工企业安全工作的科学管理

传统安全管理模式的着眼点是在系统运行阶段,致使事故防不胜防。而科学化安全管理,其着眼点是在对危险进行预先识别、分析和控制上,变“事后处理”为“事先控制”,防患于未然。企业管理者必须要转变观念,以人为本,提高专业素质,采用形式多样的人性化管理手段,才能促进现代施工尤其是隧道施工企业安全工作尽早实现科学管理。
