Introduction: Emergency situations are of the major challenges in industries. Understading the status of inter-team interaction is effective in improvement of emergency response team (ERT). The purpose of this study was to investigate the interaction space of ERP in a refinery, using the social network analysis (SNA). .Methods and Materials: In the present case study, the density indicator was ...
This paper considers the cost of preprocessing a digital terrain model (DTM) represented as a trian-gulated irregular network (TIN) so that drainage queries|e.g., what is the watershed of a query point, or how much water passes through a point given that rain is falling at a known rate|can be answered by simply evaluating a summary function. Although the worst-case storage and preprocessing cos...
One of the most important features topographic maps is stream network. Its accurate representation essential for several applications. This work evaluates quality network Brazil and Portugal's official maps. These were produced using different scales (1:10,000, 1:25,000, 1:50,000) methods (photo interpretation automatic drainage extraction). The intention this analysis to focus on data analysis...
Nitrate has been the most common chemical contaminant in water resource. This ion is introduced into the water via different ways, but more items of nitrate pollution was connected with farming-based drainage and sewage effluent. In this descriptive-analytical study, groundwater nitrate and nitrite concentrations of 8 wells on Dehloran, Ilam, Iran, were analyzed in 2015 to determine the causes ...
