The purpose of this study was to determine and evaluate of spatial distribution of gold and silver elements concentration by using geostatistical methods. This study was carried out in Ghezel Ozen area for 95 samples of lithogeochemicals. At first, Censor data was replaced and the values of outlier's data were identified using the box-Plot and Q-Q-Plot charts and reduced by the Doerffel ...
Public space is an essential element of human wellbeing and the overall development city society. This paper presents a brief outlook past present situations related to planning use public spaces in urban environments. In doing so, this addresses finding that gradually lose focus quality them, as time goes by, these are reshaping even human-unfriendly places. The purpose presented research find...
Context of contents for optimal user experience can be composed of various elements including time, spatial context, and social context. And also including global, local and personal contexts. In this paper, we proposed a representation scheme of spatial context hierarchy for optimal content services. Proposed context representation consists of time and spatial index and relations makes formal ...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
generally heavy metals exist in all soils, but soil pollution is rising by time due to human activities. soils in the proximity of mines are more pruning to pollution of heavy metals due to mine exploring and excavation. this research was carried out to evaluate the soil pollution of sepahanshahr suburb with pb, zn and cd. during a field work campaign 100 soil samples were selected randomly fro...
This study is aimed to investigate the spatial variation of soil macronutrients such as phosphorus, potassium and organic matter using different methods of Geostatistics and Geostatistical method combined with Fuzzy logic to estimate the values of this element to provide a spatial distribution map for the proper distribution of fertilizer in the plain of Uremia. Spatial variations in soil nutri...
In this paper, we have tried to analyze and asses the process of formation and spatial – structural evolution of Iranian-Islamic cities through Tehran case study as well as how to organize and effecting different factors specially modernism on urban elements. Also we have discussed about formation and emergence of Tehran and the effect of different pre modernism and postmodernism socio-economic...
Understanding distribution of soil properties at the field scale is important for improving agricultural management practices and for assessing the effects of agriculture on environmental quality. Spatial variability within soil occurs naturally due to pedogenic factors as well as land use and management strategies. The variability of soil properties within fields is often described by classica...
