Bu çalışmada, Türkiye'nin uzun vadeli aylık ortalama sıcaklıkları üç farklı enterpolasyon yöntemi kullanılarak tahmin edilmiştir. Sıcaklıklar komşu ölçüm istasyonlarına ait enlem-boylam özellikleri ve Ters Mesafe Ağırlıklı Enterpolasyon (Inverse Distance Weighting, IDW), Kriging Radyal Tabanlı Fonksiyon (Radial Basis Function, RBF) yöntemleri Yöntemler ArcGIS yazılımı altında ArcMAP programı il...

water use productivity is one of the most important factors in scientific agriculture. it is equal to 0. 7 kg of production per cubic meter of irrigation water (kg/m3) in iran which is very low in comparison with advanced countries (1 to 2 kg/m3). current research studies temporal and spatialchanges of water use productivity in hamedan province in iran using geographic information system (gis),...

A better understanding of spatial distribution groundwater level is necessary for the development strategies and sustainable use available resources. The present study evaluates over Morang Administrative District Eastern Nepal accessibility area. was realized by performing an extensive field survey during post-monsoon season 126 sites. area 1224.80 km2 gridded at 3 km x horizontal grid resolut...

Two major reverse osmosis seawater desalination plants are planned for construction in Spencer Gulf and Gulf St. Vincent, South Australia. A state-of-the-art and carefully calibrated hydrodynamic model (COHERENS) is employed to predict the fate of desalination brine in these sheltered inverse estuaries. In this study, we assume that the brine discharged has a salinity being twice that of ambien...

Effective assessments of air-pollution exposure depend on the ability to accurately predict pollutant concentrations at unmonitored locations, which can be achieved through spatial interpolation. However, most interpolation approaches currently in use are based on the Euclidean distance, which cannot account for the complex nonlinear features displayed by air-pollution distributions in the wind...

Let G be a strongly connected, weighted directed graph. We define a product distance η(i, j) for pairs i, j of vertices and form the corresponding product distance matrix. We obtain a formula for the determinant and the inverse of the product distance matrix. The edge orientation matrix of a directed tree is defined and a formula for its determinant and its inverse, when it exists, is obtained....

<p>Rapid urbanisation, industrialization, and population growth have fostered an urgent need for a green, clean-living environment. Among the many pollutants, gaseous pollutants like NO2, SO2, particle PM 2.5 10 profound negative impact on human health. In this investigation, samples of air 2.5, were taken at ten different sites inside Tirupur corporation boundaries. For locations into co...
