Background and aims: Thousands of people die in road crashes each year and several hundred thousand are disabled, as a result of road traffic accidents. Counts of fatal accidents were caused by drivers who are not comply with their jobs. Studies indicated that small percentage of people are more likely to have accidents in a similar situation, whom named as accident-prone drivers. This study ...

Abastract Introduction Road accidents is the outcome of driver behavior, road condition, vehicle status, and environmental factors. Therefore, identification and assessment of effective parameters on road accidents can be considered as an appropriate way to reduce the accident events, driving violations and increase the road safety. Determining the effects of meteorological factors on the ro...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

The occurrences of accidents on the railways are inevitable in today’s world and the factors which may cause it, except the atmospheric and accidental ones, are identified and preventable as well. Therefore, these factors can be investigated and useful actions can be performed in order to reduce these accidents. The main impetus of the present research is the statistical analysis of the causes ...

Managers from 192 companies filled out the Employee Direct Participation in Organisational Change questionnaire measuring employees' direct participation (DP) in organisational decisions. Four main forms of DP were identified: individual and group consultations, and individual and group delegation. Workplace safety was measured with the number of accidents, the number of employees working in ha...

A postulated progressing severe accident scenario has been simulated using MAAP5 code with the focus on ex-vessel cooling of molten corium in reactor cavity. Various parameters associated prediction corium–concrete interaction (MCCI) are identified. Accordingly, a sensitivity analysis is performed to assess impact these predicted cavity floor erosion depth during this MCCI accident. The index e...
