Optimization of Composite Stiffened Cylindrical Shell using PSO Algorithm

Composite stiffened cylindrical shells are widely used as primary elements in aerospace structures. In the recent years, there has been a growing research interest in optimum design of composite stiffened cylindrical shell structures for stability under buckling load.  This paper focuses upon the development of an efficient optimization of ring-stringer stiffened cylindrical shell. The opti...

Using PSO algorithm optimization for planning 103Pd seeds brachytherapy positions

Radiation therapy, is one of the treatments for cancer. Brachytherapy is a radiotherapeutic technique that a sealed radiation source is placed inside or next to the tissue and has become a mainstream treatment option for cancer. Achieving maximum dose to the gland as well as minimum injury to the adjacent tissues is a basic principle in radiation therapy. Sources configuration must be designed ...

Power Flow Optimization Using Seeker Optimization Algorithm and Pso

The objective of an Optimal Power Flow (OPF) algorithm is to find steady state operation point which minimizes generation cost, loss etc. or maximizes social welfare, loadability etc. while maintaining an acceptable system performance in terms of limits on generators’ real and reactive powers, line flow limits, output of various compensating devices etc. This paper aims to find a solution for t...

Image Quality Assessment using PSO-GSA Optimization Algorithm

In this paper, we present new method to the objective image quality evaluation based on discrete wavelet transform (DWT) and Particle Swarm Optimization and Gravitational Search algorithms (PSO-GSA). DWT is applied on the difference between the original and degraded image, which is decomposed into approximation and detail sub-bands. DWT coefficients are computed using Haar wavelet filter banks....
