Recently Non-negative Matrix Factorization (NMF) has captured a quantifiable attention in the field of information retrieval. Especially in the dimension of text summarization, it has leaped a large step in minimizing the gap between the summary produced by the man and machine. This paper is aimed at a preliminary study of a novel approach to automatic text summarization using extraction method by...
It highly deserves to remove human operators from hazardous environments or monotony routine work during pick-and-place type operation in current industrial societies; it also deserves to encourage the work in new exploration without risks on humans or objects. In order to achieve this, a novel robotic gripper is presented in this paper. A gripper is designed to grasp unknown objects with different...
This paper presents a fuzzy controller for two-finger gripper, one finger is fixed and the other is movable. Control system input / output variables ldquospeed command for servo motor driver / rate of force increaserdquo are measured and processed to model the mechanical system. A new grasping and control algorithm is proposed which adjusts the motion of one finger of the gripper without the risk...
In this paper, a new method for solving the kinematics of a mobile robot and obstacles avoidance is proposed. The method uses a genetic algorithm (GA) in solving the kinematics. Using this technique, the robot controller can adjust itself autonomously even with a malfunction in the robot. The new method was implemented and tested with different type of robot malfunctions. The results showed that,...
The harmonic pollutions in the electrical networks became one of the major factors affecting the power quality of the network. APF's represent the most convenient system used to eliminate harmonics. To achieve instantaneous harmonic compensation, the harmonic current reference should be extracted very fast. In this paper, the average technique is used to extract the harmonics current contents for...
A simple neuro-controller for a synchronous generator is presented in this paper. The controller consists of a single neuron trained on-line using the back propagation algorithm based on a modified error function. The modified error function uses the controlled variable and its derivatives. Based on the variables used in the modified error function, the controller performs the functions of terminal...
