Detection of radiological accidents and monitoring the spread of the contamination is of great importance. Following the Chernobyl accident many European countries have installed monitoring networks to perform this task. Real-time availability of automatically interpolated maps showing the spread of radioactivity during and after an accident would improve the capability of decision makers to ac...

Safety analysis according to the spatial distribution characteristics of maritime traffic accidents is critical safety management. An accident framework based on geographic information system (GIS) proposed characterize occurring in Fujian sea area 2007–2020 by employing kernel density estimation and autocorrelation techniques. The divided into various grids, each grid, mapping relationships be...

recently, hardware sensors are widely used in monitoring and measurement of water quality parameters. constraint of the instrument to measure some water quality parameters such as the 5-day biochemical oxygen demand (bod5), which are time consuming, causes efforts are diverted to the use of software sensors for online prediction of bod5. the main goal of this research is developing an appropria...

The Swiss Cheese Model (SCM) is the most popular accident causation model and is widely used throughout various industries. A debate exists in the research literature over whether the SCM remains a viable tool for accident analysis. Critics of the model suggest that it provides a sequential, oversimplified view of accidents. Conversely, proponents suggest that it embodies the concepts of system...

We present a new generalized model for the diagnosis and prediction of accidents among the Spanish workforce. Based on observational data of the accident rate in all Spanish companies over eleven years (7,519,732 accidents), we classified them in a new risk-injury contingency table (19×19). Through correspondence analysis, we obtained a structure composed of three axes whose combination identif...

â  using of prediction models is one of the methods of financial performance prediction. financial ratios are employed as predictive variable in prediction models. the main purpose of this study is to compare the incremental information content of accrual and cash ratios for prediction and evaluation of the financial performance of business entities by data mining models. in align with research...

Since the counter current flow limitation (CCFL) of two-phase has an important influence on safety analysis reactor, it is also great significance to study some characteristics and pattern transitions flow. In order explore influencing factors in hot leg under condition Loss Coolant Accident, this research, using RELAP5 simulation calculation, analyzed effect lengths path leg, shapes upper outl...

This paper aims at investigating brain injury mechanisms in adult pedestrian accidents by indepth accident analysis and accident reconstructions. In total, 120 adult pedestrian accident cases from the GIDAS database were analysed and 10 of them were reconstructed. The accident reconstructions were first carried out using multi-body system (MBS) pedestrian and car models to acquire the head impa...
