in this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (dde) is presented. the main idea is that of incorporating the driver intent in the control of the vehicle. the driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. to induce a risk...
air quality inside commuting vehicles has seldom been evaluated in iran. accordingly, this study investigates the levels of benzene, toluene, ethylbenzene and xylene (btex) during workdays characterized by heavy traffic inside taxis in tehran- iran between may 2009 and october 2010. the totals of 35 personal samples were collected onto solid sorbent tubes and the concentration of volatile organ...
background: long distance truck drivers (ldtds) and their sexual health risk behaviors have been associated with greater prevalence of sexually transmitted infections (stis), hiv and hepatitis virus transmission. however, there is no information about iranian ldtds' high-risk behaviors. the aim of this investigation was to estimate the prevalence of high-risk behaviors in iranian ldtds. methods...
background: motor vehicle traffic injuries are indeed one of the most important worldwide health problems. opioids can induce a depressant effect on the central nervous system which may increase the risk of traffic accidents. this cross-sectional case-control study was conducted in marvdasht, iran to investigate the presence of drugs in hospitalized non-fatally injured drivers of motor vehicles...
the proportion of elderly in the general population is rising, resulting in greater numbers of drivers with neurodegenerative disorders such as alzheimer’s disease (ad) and parkinson’s disease (pd). alzheimer’s disease is a progressive neurodegenerative disorder typified by memory impairment with executive dysfunction, motor problems, and/or language difficulties. parkinson’s disease is a progr...

Background and aims: Car Accident reports shows that the main cause of accidents is driver error and unsafe behavior. Workload of the major factors affecting driver that has a direct impact on the incidence of traffic accidents. This study aimed to evaluate aspects of mental work load of auditory-verbal secondary task was performed while driving. Methods: Twenty professional bus driver randoml...
The conjugation of High Performance Computing (HPC) and Grid paradigm with applications based on commercial software is one among the major challenges of today e-Infrastructures. Several research communities from either industry or academia need to run high parallel applications based on licensed
Over the past 30 years, numerical methods and simulation tools for fluid dynamic problems have advanced as a new discipline, namely, computational fluid dynamics (CFD). Although a wide spectrum of flow regimes are encountered in many areas of science and engineering, simulation of compressible flow has been the major driver for developing computational algorithms and tools. This is probably due...
