pinch analysis (pa) is used as a powerful tool for targeting and synthesis of heat and mass exchange networks. pa for solving includes extended and complex operation although having a simple concept. according to this matter, need for creating a pa software is clear hence famous an american and european cooperation introduce extensive and powerful software by applying advanced programming langu...

At first glance, the domain of health is no typical area to applicate Geographical Information Systems (GIS). Nevertheless, the recent development clearly shows that also within the domains of environmental health, disease ecology and public health GIS have become an indispensable tool for processing, analysing and visualising spatial data. In the field of geographical epidemiology, GIS are use...

GIS has shown promise in Project Based Learning (PBL) environments, but many obstacles exist in its integration into school curriculums. This article discusses the development and utilization of an online GIS tool that was created to illustrate that the perceptual gap between relevance and ease of use of GIS software can be bridged at the K–12 level. This online GIS tool, referred to as the H2O...

GIS is becoming an essential tool for utility companies, especially water companies, which have found an excellent way to manage and assess their assets. This paper presents an ArcView® GIS extension called GISRed, which is a customized application oriented to the task of water network modelling. GISRed is capable of simulating, analyzing and retrieving the actual network status under certain c...

Being a set of techniques for analyzing spatial patterns in buildings and cities, space syntax has been implemented in various software of spatial analysis. Due to the common requirement of handling spatial information, a significant portion of this spatial analysis software is built upon a geographic information system (GIS). Although these spatial analysis software may be available free of ch...

Gas ionization sensor (GIS), made of two parallel plates, works on measuring the breakdown voltage of gases that is unique for each gas. The gas breakdown inside the gas chamber occurs due to the ionization of gas molecules by accelerated electron impacts. The acceleration of electrons is very depended on the effective electric field they experience. It is shown that metallic or semiconductor n...

Next generation of GIS software should be able to manipulate and analyse complex situations of real world phenomena. One of the desired components in such software or system is the geometric modeling that works with 3D spatial operations. This paper presents a portion of problem that we currently attempt to solve, that is the 3D spatial operations for Geo DBMS. Some popular spatial operations i...
