background and objectives: day-shift taxi drivers have a long duration of direct sun exposure. however, the efficiency of this occupational exposure in vitamin d synthesis has not been addressed yet. the aim of this study was to assess the vitamin d status of taxi drivers in tehran, and examine vitamin d status association with some anthropometric and circulating biomarkers. materials and metho...

This paper presents a design procedure for an adaptive power management control strategy based on a driving cycle recognition algorithm. The design goal of the control strategy is to minimize fuel consumption and engine-out NOx, HC and CO emissions on a set of diversified driving schedules. Seven facility-specific drive cycles are considered to represent different driving scenarios. For each fa...

driving is a complex psychomotor task involving distinct cognitive, perceptual and decision making skills. it needs to more concentration and alertness to driving safe. several studies have shown the potential effects of alcohol in crash production by epidemiological and laboratory analysis. alcohol is obviously the most common single cause of traffic accidents in america. a review of the relat...

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...

Nowadays, machine life and traffic jams are part of life and expanded. While economic and welfare benefits of the expansion of communication and the speed of transportation goods and people, the number and severity of traffic accidents increased. According to the World Health Organization, in recent years, Traffic accidents are recognized as the ninth cause of death in the world. In Iran, Traff...

Background Adequate access to health services has tremendous effects on the usefulness and efficiency of health care. Therefore, this study aimed to investigate the access of girls under the age of 14 years old to pharmacies in Kermanshah, Iran. Materials and Methods In this cross-sectional study, the access of Results In terms of access to 25 pharmacies through walking, the findings revealed ...

In many areas, experts often exhibit specialised eye movement behaviour which allows for more efficient task execution than novices. In some areas (e.g. Radiology), showing this pattern of eye movement behaviour to novices can help cue overt visual attention to more relevant areas; which allows for more efficient task completion. We present a study which investigated the effects of eye movement...

Driving behavior in traffic has been modeled quite successfully in simulation software using predefined car-following models rules. However, because most car-following models assume that vehicles could keep a safety distance away to avoid crash related conflicts; they are not capable to capture naturalistic driving behavior during safety-critical events. Also, vehicle detailed lateral maneuveri...

Operating a robot safely and efficiently can be considerably challenging in an interactive and complex environment. Other surrounding agents may be cooperative or adversarial in their interactions with the robot. It will be desirable to develop control strategies that can enable the robot agent to handle diverse situations and respond with appropriate behaviors in an interactive environment. In...
