An adaptive nonlinear control law that incorporates the manipulator dynamics as well as dynamics of the actuator is developed in this article. The technique is based on nonlinear feedback linearization. The electrical parameters of the actuator are considered to be of uncertain values. In contrast to known methods the robot position is the only measurement available, a nonlinear observer is des...

Run off resulted from rainfall is the main way of receiving water in most parts of the World. Therefore, prediction of runoff volume resulted from rainfall is getting more and more important in control, harvesting and management of surface water. In this research a number of machine learning and data mining methods including support vector machines, regression trees (CART algorithm), model tree...

assess the ecological effects of economic activity on the water, earth and man in the iranian economy approach using input - output tablewater is a vital resource for each biological and economic phenomenon. water is considered as a production input. production is not possible without water in all economic sectors. also, the environment including air, soil, fauna and plants utilize water in the...

potato image segmentation is an important part of image-based potato defect detection. this paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on genetic algorithm (ga) optimization and morphological operators. the proposed potato color image segmentation is robust against variation of background, distance and ...
