For any given road layout or curvature skid resistance as property of pavement surface and tyre is a decisive factor limiting the speed threshold for safe driving. Skid resistance is no fixed value and is significantly lowered in case of precipitation depending on form and rate. A further influence factor in such cases is the macro texture of pavements due to their capacity to hold precipitatio...

A hierarchical Bayesian space-time (HBST) model, an extension of the class of dynamic linear models to space-time processes, is proposed for the statistical modelling of radioactivity deposition after a nuclear accident. It explicitly handles uncertainties associated with (i) predictions of depositions from a long-range atmospheric dispersal model, (ii) in-situ gamma ray measurements and (iii) ...

car manufacturing industry accident’s rates from three major companies are analyzed. totally 1325 accidents with 4 cases of fatality were recorded. accident rates per 100 full-time workers have gradually increased from 5.3 to 8.7 during 3 years of study. most of the accidents occurred during the primary hours of the work, strains and sprains represented the most frequently occurring type of inj...

background because of occupational accidents, permanent disabilities and deaths occur and economic and workday losses emerge. objectives the purpose of the present study was to investigate the factors responsible for occupational accidents occurred in iran. patients and methods the current study analyzed 1464 occupational accidents recorded by the ministry of labor and social affairs’ offices i...

A three–module ecological model for assessment of radiological consequences (EMARC) of accidental fallout was developed to estimate the internal dose. The model was adapted for ecological and economic conditions of Ukraine after the Chernobyl accident. The model takes into account the main natural mechanisms of changes in level of agricultural production pollution such as transformation of bioa...

The eleven nuclear power plants in operation, under construction and a well-planned plant in the east coast of China generally use seawater for reactor cooling. In this study, an oceanic dispersion assessment system based on a database of tidal harmonic constants is developed. This system can calculate the tidal current without a large computational cost, and it is possible to calculate real-ti...

Spatial data mining recently emerges from a number of real applications, such as real-estate marketing, urban planning, weather forecasting, medical image analysis, road traffic accident analysis, etc. It demands for efficient solutions for many new, expensive, and complicated problems. In this paper, we investigate a proximity matching problem among clusters and features. The investigation inv...

The occurrences of accidents on the railways are inevitable in today’s world and the factors which may cause it, except the atmospheric and accidental ones, are identified and preventable as well. Therefore, these factors can be investigated and useful actions can be performed in order to reduce these accidents. The main impetus of the present research is the statistical analysis of the causes ...

original article   various aspects of work and occupational diversity and the complexity of the nursing profession have a significant impact on the incidence rate of unsafe acts and consequences of accidents. in this regard, safety attitude will have a significant impact on occupational accidents among nursing personnel. the aim of this study was to assess safety attitude among nurses and its r...
