investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...

qorveh – dehgolan aquifer is one of the ground water resources in kurdistan. increase in pumping of water has dropped water table level significantly. this study considers the relationship of fluctuations in precipitation, humidity and evaporation with ground water table level. after preparing the base map and the rainfall data accuracy, isohyetal map of basin was drown. based on isohyetal ma...

We present a method for refining depth information generated by a stereo-matching algorithm with the goal to provide depthaware photo-effect applications. Our key idea is to use structural features of the base image to enhance the depth information. Our method pre-processes the original disparity map by revising the sky region and removing incorrect data (on the left-side of the disparity map) ...

In investigation of pedological criterion onland degradation in Quaternary rock units, first, a part of the Rude-Shoor watershed area was selected.

In the process of constructing a concept map, a common problem is how to achieve a correct topological distribution of the concepts created. The project described in this paper uses Case Based Reasoning techniques to develop a Concept Map Topology Counselor that suggests improvements to a concept map based on its layout. The case base is constructed using examples of concept maps that present t...

To investigate pedological criterion on land degradation in Quaternary rock units, at first, a part of the shoor watershed area was selected. After distinguishing target area, slope classes, land use and geology maps were created, then map of units were founded by overlaying and crossing these maps. In this research three indices of erodibility, salinity and permeability of soils were considere...
