desertification process as a great problem affects most of the countries in the world specially developing countries. this process has a high rate in arid and semi-arid countries such as iran. the main objective of this research was to investigate land degradation status and desertification mapping of kashan area. different studies have been carried out in the world in order to assess desertifi...

In this article we propose a general and robust technique for modeling surfaces through the analysis of multiple image acquisitions. Our method is based on the minimization of the multi-view texture mismatch and is inherently multi-resolution, as the surface is obtained through a progressive re0nement of hierarchical radial basis functions. ? 2002 Elsevier Science B.V.

We establish some stability results concerning the general cubic functional equation f(x+ ky)− kf(x+ y) + kf(x− y)− f(x− ky) = 2k(k − 1)f(y) for fixed k ∈ N\{1} in the fuzzy normed spaces. More precisely, we show under some suitable conditions that an approximately cubic function can be approximated by a cubic mapping in a fuzzy sense and we establish that the existence of a solution for any ap...
