Fractured reservoirs contain about 85 and 90 percent of oil and gas resources respectively in Iran. A comprehensive study and investigation of fractures as the main factor affecting fluid flow or perhaps barrier seems necessary for reservoir development studies. High degrees of heterogeneity and sparseness of data have incapacitated conventional deterministic methods in fracture network modelin...

Object manipulation techniques in robotics can be categorized in two major groups including manipulation with and without grasp. The aim of this paper is to develop an object manipulation method where in addition to being grasp-less, the manipulation task is done in a passive approach. In this method, linear and angular positions of the object are changed and its manipulation path is controlled...

In function based object recognition an object category is represented by knowledge about object function Function based approaches are important because they provide a principled means of constructing generic recognition systems Our work concentrates speci cally on the relation between shape and function of rigid D objects Recognition of an observed shape is performed by reasoning about the fu...
