Traditional kernel methods for estimating the spatially-varying density of points in a spatial point pattern may exhibit unrealistic artefacts, addition to familiar problems bias and over- or under-smoothing. Performance can be improved by using diffusion smoothing, which smoothing is heat on domain. This paper develops into practical statistical methodology two-dimensional data. We clarify adv...
Ecology, biogeography and conservation biology, among other disciplines, often rely on species identity, distribution abundance to perceive explain patterns in space time. Yet, are not independent units the way they interact with their environment. Species perform similar roles networks ecosystems, at least partial redundancy or difference of might co-existence, competitive exclusion reflected ...
In Zagros forest ecosystem, spatial variability of soil and vegetation properties are controlled by series of physical and biological parameters including topographical and anthropogenic factors. Distribution patterns of these properties are greatly variable. In the current study, geostatistics and fractal theory were used to assess the spatial variability of tree canopy and soil bulk density i...
Spatial planning approaches along with complication of societies are being changed. These changes and transformations have reflected themselves in increasing diversification of economic patterns, people, group, organization, and institution’s mobility. While in less developed network societies some of the concepts including “distance” and “movement “are relatively losing their importance , some...
Introduction Temperature is one of the important elements of weather, resulting in part from solar energy absorbed by the effects of the Earth's surface and is converted to thermal energy. Maximum temperatures in the hot period of the year, especially in the hours after the city, should be given more attention. Analyzing the maximum temperature can also be normal evaluation mechanism to eval...
