degradation model was introduced as an instrument of environmental impact assessment (eia) in iran. several methods are introduced in rapid environmental assessment, but none of them have evaluated landscape level. thus, the main objective of this research is to introduce a new spatial method for eia by using landscape metrics. a benefit of rapid assessment by using ecological landscape metrics...

Quality of urban areas and improvement of it have always been considered as one of the main issues in the process of urbanization. It might be possible to consider this importance as the result of fundamental changes in intellectual patterns during the past two decades in one side and its proposal in all aspects of human life on the other side though this is one of the main influential concepts...

UK forests and woodlands are often of considerable value to biodiversity. There is now a growing need to evaluate the impacts of forest management on biodiversity, in order to maintain and enhance the wildlife value at the landscape scale. The development of biodiversity evaluation tools will enable forest and land managers to make informed choices at this scale in order to provide sustainable ...

We analytically put the concept of public administration into perspective in this paper. In the process, we traced its genealogy and, its theoretical provisions as well as the implications and challenges of these provisonal at each stage of its development. We specifically zeroed-in on the practical applications of these provisons in a country like Nigeria. Prominence was given to the features ...

The scene simulation is one of the kernel methods in developing the navigation simulator, and terrain is one of the important components of the scene simulation. According to the basic request on terrain protraction in the visual system of navigation simulatorand the software and hardware platform of the existing navigation simulator. Many useful results of bivariable functions have been obtain...

BACKGROUND Landscape ethnoecology focuses on the ecological features of the landscape, how the landscape is perceived, and used by people who live in it. Though studying folk classifications of species has a long history, the comparative study of habitat classifications is just beginning. I studied the habitat classification of herders in a Hungarian steppe, and compared it to classifications o...

We survey some recent results on the reconstruction of discontinuities by boundary measurements for elasticity and related systems in two dimensions. Our main tool is a new type of complex geometrical optics solutions.

We introduce a new texture representation that combines standard sampling, to be bilinearly interpolated in smoothly varying regions, with customizable discontinuities, to model sharp boundaries between these regions. The structure consists of a standard signal texture, plus a second texture we call pinchmap, which encodes discontinuities along generally curved lines; at rendering time the frag...
