Increasing vehicle popularity and, in the meantime, traffic accidents, is one of the most important death factors these days. Many policies have been implemented to decrease accident injuries and damages, and to increase safety. Between three effective factors in accidents, including human, vehicle, and road, human factor is known as the most important one. Human behavior during driving is deri...

the efficiency of three statistical models, ahp surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in chehel-chai watershed in golestan province, iran. in current study the hazard map was prepared according to the top model of landslide hazard map. chehel-chai watershed is located as one of go...

the main purpose of this study is landslide hazard assessment the ziarat watershed (golestan province) using information value and lnrf models within geographic information. at first stage, a landslide inventory map was prepared in the study area using earlier reports and aerial photographs, and a total of 50 landslides was mapped and out of which 35 (70%) were randomly selected for building la...

This study demonstrates that, among large U.S. bank holding companies (BHCs), the largest ones are exposed to more operational risk. Specifically, they have higher losses per dollar of total assets, a result largely driven by BHCs' failure meet professional obligations clients and/or faulty product design. Operational risk at institutions is also found to: (i) be persistent, (ii) countercyclica...

This paper gives step-by-step instructions for assessing aquatic selenium hazards associated with mining. The procedure was developed to provide the U.S. Forest Service with a proactive capability for determining the risk of selenium pollution when it reviews mine permit applications in accordance with the National Environmental Policy Act (NEPA). The procedural framework is constructed in a de...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.
