The Fukushima Daiichi Nuclear Power Plant accident caused an accumulation of 137Cs in coastal sediment. supply from rivers to the ocean can affect long-term fate Since river basins include large decontaminated and evacuation order areas, considering decontamination work resumption agriculture is important for predicting supply. We conducted a 30-year prediction using distributed radiocesium mod...

Today’s vehicle collision prediction algorithms are rule-based, and have not benefited from the recent developments in deep learning. This is because it is almost impossible to collect a large amount of collision data from the real world. To address this challenge, we collect a large accident data set using a popular video game named GTA V. Using this accident data set, we develop efficient pre...

This report describes a Bayesian method for estimating accident rates at individual sites, which takes into account the fact that the total traffic count usually used to measure exposure is generally not known with certainty. The first step involves deriving an approximation for the probability distribution of total traffic conditioned on a short count sample. This approximation is then used to...

Introduction: Sleepiness may predispose drivers to road traffic accidents. Obstructive Sleep Apnea Syndrome is the most common medical cause of sleepiness. Hence increased neck circumference (NC) and obesity are known as obstructive sleep apnea syndrome risk factors. This study was conducted to assess OSAS role in occurrence of road traffic accidents in sleeping drivers of commercial heavy veh...

understanding the implication of genotype-by-environment interaction (gei) and improving stability of crop yield in a target production environment is important in plant breeding. in this research, we used the ammi (additive main effects and multiplicative interaction) model to identify the stable genotype(s) by predictive accuracy of yield data. results of this study indicated that the fgh tes...

regarding to increased use of groundwater resources, it seems necessary to have more accurate knowledge of characteristics of aquifers in order to improved usage and accurate management of these resources. in this study, we simulated groundwater flow of qazvin aquifer usingvisual modflow model, collecting data and statistics, as well as using different studies. the simulation model has operated...

many studies have been conducted focusing on the effects of friction coefficient or texture depth on the highway accident risk. however, combined effects of these parameters have not been still addressed. in this research the interaction between friction coefficient, texture depth and accident rate in 30 freeway sections were examined. the accident data were gathered and an apparatus was design...

This paper used the data of automobile traffic accidents from 2018 to 2020 in Chinese National Automobile Accident In-Depth Investigation System. The prediction features accident severity are innovated. Four that did not participate importance ranking were added: location, form, road information, and collision speed. Eight (engine capacity, hour day, age vehicle, month year, day week, band driv...
