There has been considerable research conducted on the development of statistical models for predicting motor vehicle crashes on highway facilities. These models have often been employed to estimate the number of crashes per unit of time for an entire highway segment or intersection, without distinguishing the influence different sub-groups have on crash risk. The two most important sub-groups t...

Car body deformation modeling plays a very important role in crash accident analyses, as well as in safe car body design. The determination of the energy absorbed by the deformation and the corresponding Energy Equivalent Speed can be of key importance, however their precise determination is a very difficult task. Although, using the results of crash tests, intelligent and soft methods offer an...

Abstract Background and purpose:Work-related accidents are causing distress and economic losses. This study was conducted to estimate the burden of occupational accidents by the use of disability-adjusted life year (DALY) calculation in Iranian Social Security Organization (ISSO), Tehran province, between 2008 and 2011 time frame. Materials and Methods:This descriptive analytical study was cond...

background: this study provides a national profile of major work safety accidents in china, which cause more than 10 fatalities per accident, intended to provide scientific basis for prevention measures and strategies to reduce major work safety accidents and deaths. methods: data from 2003-2012 census of major work safety accidents were collected from state administration of work safety system...

introduction: the effects of accidents vary from minor injuries to fatalities and from insignificant damage to very severe damage to the environment and property. in order to prevent accidents in the work place, the root causes of and events should be identified using a systematic method and the results should be published. the current study aims to investigate the given causes of an accident i...

This paper presents the dynamic modeling and design of micro motion compliant parallel mechanism with flexible intermediate links and rigid moving platform. Modeling of mechanism is described with closed kinematic loops and the dynamic equations are derived using Lagrange multipliers and Kane’s methods. Euler-Bernoulli beam theory is considered for modeling the intermediate flexible link. Based...
