Abstract We propose in this paper a method based on mathematical morphology for building extraction in a very high spatial resolution satellite urban areas images, it requires no exogenous variable, unlike other approaches (e.g., using elevation data or supervised classification post processing [1]). It consists on using several morphological operations such as hit-or-miss transform (HMT), the geodesic reconstruction and smoothing. Comparative studies of... We propose in this paper a method based on mathematical morphology for building extraction in a very high spatial resolution satellite urban areas images, it requires no exogenous variable, unlike other approaches (e.g., using elevation data or supervised classification post processing [1]). It consists on using several morphological operations such as hit-or-miss transform (HMT), the geodesic reconstruction and smoothing. Comparative studies of two methods (including that of [1]) are presented showing the interest of the approach we used. Read More Read Less

Abstract In this paper, we demonstrate the analytical method for the solving of the inverse kinematics of 6 DOF manipulator arm, the FANUC 200IC, those solutions can be chosen after analysis of the Jacobian matrix, simplification and decomposition of this matrix leads us to solve a nonlinear equation with two variable, that we will limit the number of solution found, and that... In this paper, we demonstrate the analytical method for the solving of the inverse kinematics of 6 DOF manipulator arm, the FANUC 200IC, those solutions can be chosen after analysis of the Jacobian matrix, simplification and decomposition of this matrix leads us to solve a nonlinear equation with two variable, that we will limit the number of solution found, and that will give us the real workspace of robot accessible by the end-effector. We validate our work by conducting a simulation software platform that allows us to verify the results of manipulation in a virtual reality environment based on VRML and Matlab software, integration with the CAD model.

Abstract The goal of this article is to design an interface for social network according to aesthetic, human computer interaction principles and find an appropriate location for items on a page. For this purpose, we studied 5 aesthetic principles(golden section, dynamic symmetry, Gestalt laws, color harmony and Goethe’s color theory), the effect of web aesthetic on users first credibility perception, the importance... The goal of this article is to design an interface for social network according to aesthetic, human computer interaction principles and find an appropriate location for items on a page. For this purpose, we studied 5 aesthetic principles(golden section, dynamic symmetry, Gestalt laws, color harmony and Goethe’s color theory), the effect of web aesthetic on users first credibility perception, the importance of user profile for designing interface and Motivation- Hygiene theory. The method in this paper was experimental for which a group of participants were asked to draw what they expect their profile page should look like. Subjects were 18 students from Shiraz University of Technology. According to important factors for designing user interface, analyzing these studies, doing experiments, and collecting participant’s opinions, drawings and designs, we presented a model for user profile and home interface design and then we analyze them.
