in the present paper, employing a complete model of a passenger car, contribution of various components and assemblies in the frontal crash energy absorption is determined. thickness of components with more remarkable contribution is increased to improve the occupant safety. furthermore, effects of substituting the metallic bumper with one fabricated from gmt materials on the frontal crash beha...

Traditionally, transportation safety analysts have used the empirical Bayes (EB) method to improve the estimate of the long-term mean of individual sites; to correct for the regression-to-the-mean (RTM) bias in before-after studies; and to identify hotspots or high risk locations. The EB method combines two different sources of information: (1) the expected number of crashes estimated via crash...

Road traffic crashes (RTCs) are a major global public health problem and cause substantial burden on national economy healthcare. There is little systematic understanding of the geography RTCs spatial correlations in Middle-East region, particularly Oman where leading disability-adjusted life years lost. The overarching goal this paper to evaluate temporal dimensions, identifying high risk area...

this paper presents the results obtained from the life cycle assessment (lca) of the productionof sicilian artichokes (cynara scolymus) with the aim of reducing impacts, interpreting the results, suggesting possible improvements and enriching the sustainability knowledge already existing in the agro food field. artichokes represent one of the excellent italian agricultural products even if stil...

background and objectives: in many studies, chronic diseases are associated with incidence of driving accident. the main objective of the present study is investigation the effect of physical and mental disorders status of bus drivers on the occurrence of crashes. materials and methods: this research is a cross-sectional and descriptive-analytical study that was performed on 665 bus drivers' pu...

Stock price crash risk is a phenomenon in which stock prices are subject to severe negative and sudden adjustments. So far, different approaches have been proposed to model and predict  the  stock price crash risk, which in most cases have been the main emphasis on the factors affecting it, and often traditional methods have been used for prediction. On the other hand, using  Meta Heuristic Alg...

BACKGROUND Infectious diseases often demonstrate heterogeneity of transmission among host populations. This heterogeneity reduces the efficacy of control strategies, but also implies that focusing control strategies on "hotspots" of transmission could be highly effective. METHODS AND FINDINGS In order to identify hotspots of malaria transmission, we analysed longitudinal data on febrile malar...
