"Unintended-acceleration" automobile accidents typically begin when the driver first enters the car, starts the engine, and intends to press his/her right foot on the brake while shifting from Park to a drive gear (Drive or Reverse). The driver reports an unintended (uncommanded) full-throttle acceleration, coupled with a loss of braking, until the episode ends in a crash. Pedal misapplications...

Objectives: Most studies have performed to identify the affective variables in using mobile phone by drivers based on interview and questionnaire. In this study call answering rate while driving was investigated in a sample of male postgraduate students of a university in Tehran by a driving simulator. Methods: Six driving scenario designed differing in risk of driving. Answer rate to mobile...

This paper deals with the real-time energy management strategies for a hybrid energy storage system (HESS), including a battery and a supercapacitor (SC), for an electric city bus. The most attractive advantage deriving from HESSs is the possibility of reducing the battery current stress to extend its lifetime. To quantitatively compare the effects of different control strategies on reducing ba...

alzheimer's disease (ad), a common and debilitating neurodegenerative disorder, affect more than 65 million individuals throughout the world. this disability plays a crucial role in daily activities such as driving. several studies have investigated the relationship between cognitive functions and driving safety. the current study revises the literature on the relation between road safety ...

In this paper a multi-variable LPV/H∞ control approach is applied to design a strategy for power source coordination within a multi-source energy system. Three different kinds of power sources – fuel cell, battery and ultracapacitor – compose the power supply system of an electric vehicle. All sources are current-controlled and paralleled together with their associated DC-DC converters on a com...

the current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. the unece group of experts on pollution and energy (grpe) under particle measurement program (pmp) are unde...

in this paper, the effects of input temperature and compression ratio on the net output work and efficiency of the air standard cycles, i.e. atkinson cycle, diesel cycle and otto cycle are analyzed. we assumed that the compression and power processes are adiabatic and reversible and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ...

Objective: High risk behaviors among women can have detrimental consequences on this critical group of society and its increasing rate expose them to more serious dangers. In the light of these issues, the present study aimed to assess the prevalence of high risk behaviors of women living in Tehran. Hopefully, the study results may help take some measures to decrease high risk behaviors and sol...
