With their increasing availability and quantity, remote sensing images have become an invaluable data source for geographic research and beyond. The detection and analysis of spatial patterns from such images and other kinds of geographic fields, constitute a core aspect of Geographic Information Science. Per-cell analysis, where one cell’s characteristics are considered (geo-atom), and interac...

Resequencing problem is a crucial issue in communication systems, databases, production and information networks because correct processing of information by them may often be performed only if original order of packets, queries, jobs is preserved. In this paper consideration is given to one of the queueing systems that may model processes of discrete nature where resequencing phenomenon may ar...

present communication deals with the study of four village fish culture ponds (two wild and two managed ponds) from district hisar of haryana, india was undertaken, to correlate the water quality and biological cycles in ponds with fish production. studies have revealed that the ponds are in good trophic status. chlorides, total hardness, calcium, magnesium, biochemical oxygen demand (bod), pho...

Background & Aims of the Study: Due to the increased human activities around the Agh Gel wetland, this study aimed to measured accumulations of heavy metals (Ni, Pb and Zn) in the surface sediment samples taken from this wetland. Materials & Methods: Samples were taken from 10 stations and exposed to bulk digestion and chemical partitioning. Finally, Ni, Pb and Zn conce...

Currently, Geo-data-mining and knowledge discovering, new kernel of GIS spatial analysis study, which help breaking theoretic limitation of Geo-expert system and revealing an innovative research roadmap for new era Geo-information sciences, represent latest researching trend of GIS. Various research communities have tried to applying or revising mathematic tools as probability theory, spatial s...

Objective Pacific Northwest National Laboratory hosted an intern-based web application development contest in the summer of 2016 centered around developing novel chemical surveillance applications to aid in health situational awareness. Making up the three teams were three graduate students (n=9) from various US schools majoring in nonpublic health domains, such as computer sicence and user des...

background: soil serves as a major reservoir for contaminants as it can bind to various chemicals. the aim of this study was to evaluate the levels of some metals (cd, cu, fe and v) in soil samples collected from different stations of ahvaz industrial complex ii to determine the natural and anthropogenic contribution of metal in the soil. methods: this was an experimental study that carried out...
