Rapid growth of computer network scales has made traffic matrix estimation essential in network management. It can be used in load balancing, traffic detecting and so on. Since traffic should be considered temporally and spatially, prediction is complicated. Tracking dynamic changes of traffic, reducing estimation errors and increasing robustness to noise(More)
Robot path planning is an important part of the development of autonomous systems. Numerous strategies have been proposed in the literature regarding mobile robots but trajectory planning for manipulators is considerably more difficult since the entire structure can move and therefore produce collisions with surrounding obstacles. This paper presents an(More)
Burnout is an unpleasant and dysfunctional condition that both individuals and organizations would like to change. Job burnout is a consequence of the perceived disparity between the demands of the job and the resources (both material and emotional) that an employee has available to him or her. The factors influential on burnout have been indicated in many(More)
Cognitive method is used in this research to create portfilo of movement robot manipulator. Gradient descent (GD) fuzzy controller was used and robot’s postures and trajectory were expected in MATLAB/SIMULINK environment. Fuzzy logic controller (FLC) is an influential nonlinear controller to certain and uncertain systems which it is based on artificial(More)
In the present study, Fe-Mo/Al2O3 and Ni-Mo/Al2O3 catalysts were prepared using impregnation method. The structures of the catalysts were studied using XRD, BET and H2-TPR techniques. Activities of both catalysts were investigated in a fixed-bed reactor for Methane Steam Reforming (MSR) reaction. The results indicated that Ni-Mo/Al2O3 catalyst system showed(More)
