The paper presents optimization of line parameters in order to reducing the intensity of the electric field with the use of particle swarm optimization (PSO). Simulations of the electric field intensity have been curried out for a different heights and distances for a building wall located in the vicinity of a power line.

You will get an overview about the nature of trade theory. Many terms related international trade here will be discussed. Overview of Mercantilism we will discuss here. Theory of absolute advantage will be deeply discussed here. Comparative Advantage related the advantage term here I will describe. In this article the ideas of Heckscher-Olin Theory, new Trade Theory and the theory of Porter’s Diamond will be discussed. By this article, we will be able to clearly understand international trade. WE will be able to compare and contrast different trade theories.

In this paper we present the results on the existence of fixed points of system of mappings in generalized metric spaces generalizing the result of Diaz and Margolis. Also the “local fixed point theorems” of a system of such mappings both in generalized and ordinary metric spaces are stated. Banach fixed point theorem and many others are consequences of our results.
