In this paper modified simulated annealing (MSA) and particle swarm optimization (PSO) techniques are proposed to minimize total losses in a network system with flexible AC transmission systems (FACTS) devices. The problem is decomposed in two sub-problems. The first sub-problem is optimal placement of FACTS devices using line loss sensitivity index and the second sub-problem is the load flow with...
The paper presents a novel and efficient method of regular geometric shape detection from gray scale images. Artificial ant based methods have not been used much in the field of image processing. This paper demonstrates how artificial ants can be used effectively to extract regular geometric shapes from images. We propose here ant regeneration and recombination system (ARRS), an entirely new approach...
The paper proposes two novel and efficient methods of circle detection from gray scale images. As a tool, we have used in one scheme ant colony algorithm. In other scheme, we have used ant regeneration and recombination system (ARRS), an entirely new approach developed by ourselves. In both the schemes presented here, three common steps were followed. Firstly, MATLAB edge detection operator converts...
