because every day production of refuse material is increasing, interest in the development of biogas units in many countries, both as traditional and industrial plants, has been increased. about 74 million tons of methane gas is produced from cattle dung and 40 million tons is produced only from urban solid wastes in the world annually .this would influence the greenhouse effect india and china...

this paper studies housing choice under fuzzy circumstances. in this article, fuzzy distance method is employed for selection process. methodology of housing choice with fuzzy distance approach is based on the minimizing fuzzy distance of features from desired amount under fuzzy condition. meanwhile, in the discrete choice models, housing choice is based on utility maximizing of available optio...

Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...

nowadays, with population growth in urban areas, providing safe water and health is considered basic needs of human, alongside the various pollutants due to urban activities, agriculture and industrial areas on adjacent ranges into urban water resources around the environment is such that study necessary to prevent the pollution of water resources and identification of pollution sources shows. ...

One of the fundamental social and economic characteristics of the southern countries is the lack of development of spatial planning system whose symptom is the irregular expansion of urban settlements. Due to the ecological traits and national policy-making manner, this expansion has caused the centralization of regional metropolises in these countries. In the geographical spaces of Iran, speci...

BACKGROUND The Israel Defense Forces implemented a pilot teledermatology service in primary clinics. OBJECTIVES To assess user satisfaction and clinical short-term effectiveness of a computerized store and forward teledermatology service in urban and rural units. METHODS A multi-center prospective uncontrolled cohort pilot trial was conducted for a period of 6 months. Primary care physician...

The spatial characteristics of land cover are useful for understanding the various impacts of human activity on the overall ecological conditions of the urban environment. The multi-temporal Landsat images (TM) between the years of 1990 and 2003 were used together with the Geographic Information System (GIS) techniques to evaluate the environmental changes in the area around Gabal El Hamza and ...

The study of urban spatial interaction is closely linked to that of economic geography, urban planning, regional development, and so on. Currently, this topic is generating a great deal of interest among researchers who are striving to find accurate ways to measure urban spatial interaction. Classical spatial interaction models lack theoretical guidance and require complicated parameter-adjusti...
