Core degradation and material migration research is one of the key areas in severe accident research. A review of core degradation and melting materials immigration research in light-water reactor is important to encourage relevant research. In this paper, both relevant experiments and numerical analyses are reviewed. Due to their high cost, there have only been a few experiments on severe acci...

Pavement rehabilitation could affect the accident severity index (ASI) since restoration measures means more safety for road users. No research or project has been carried out to identify hazard points to build a linear model based on crash severity index. One of the very popular accident severity index models used in all countries is based on linear models to rehabilitate pavements and this pa...

Traffic accidents directly influence public safety and economic development; thus, the prevention of traffic is great importance in urban transportation. The accurate prediction can assist departments to better control prevent accidents. Thus, this paper proposes a deep learning method named attention-based residual dilated network (ARDN), extract essential information from multi-source dataset...

background: pre-chlorination of raw water containing natural organic matters may lead to forming harmful disinfection by-products such as trihalomethanes (thms), the measurement of which needs expensive advanced analytical instruments. this study was conducted to anticipate thms formation potential in bandar abbas drinking water system using cheap and simple experiments and a mathematical model...

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...

background: this study attempted to investigate traffic accident fatalities during 2004-2009 and the effect of fuel rationing on traffic accident fatalities .   materials and methods: this was a cross-sectional study on available data of all traffic accident fatalities in fars province, iran, during 2004-2009. to identify and fit the best model, various instruments, including the autocorrelatio...
