In this paper, the gravitational search algorithm (GSA) is proposed as a method for controlling opening and closing of airplane wing tires. The GSA used to find optimum proportional-integral-derivative (PID) controller, which controls tires during take-off landing. addition, suggested an approach overcoming absence transfer function, usually required design PID. use expected improve system. Two...

Predicting disease is usually done based on the experience and knowledge of doctor. Diagnosis such a traditionally less effective. The development medical diagnosis machine learning in terms prediction provides more accurate than traditional way. In predicting can use artificial neural networks. network consists various algorithms, one which Backpropagation Algorithm. this paper it proposed tha...

in this work, harmony search meta-heuristic optimization algorithm has been developed for aerodynamic shape optimization problem for the first time. the aerodynamic shape, which has been investigated, is an airfoil with parces method for its shape parameterization. the problem was minimization of aerodynamic objective function using inverse design method and the objective function has been the ...

In this paper, the modified linearized Phillips-Heffron model is utilized to theoretically analyze asingle-machine infinite-bus (SMIB) installed with SSSC. Then, the results of this analysis are used forassessing the potential of an SSSC supplementary controller to improve the dynamic stability of apower system. This is carried out by measuring the electromechanical controllability through sing...

cost optimization of the reinforced concrete cantilever soil retaining wall of a given height satisfying some structural and geotechnical design constraints is performed utilizing harmony search and improved harmony search algorithms. the objective function considered is the cost of the structure, and design is based on aci 318-05. this function is minimized subjected to design constraints. a n...
