We consider wireless power transfer, realized by means of resonant reactive magnetic coupling, between one transmitter and two receivers. It is shown that, by applying a rigorous analytical procedure, maximum power transfer can be achieved by appropriately selecting the load values and closed form formulas for the latter are given. Similarly, closed form formulas for load values that maximize efficiency...
The Electromagnetism-like (EM) algorithm is a population-based stochastic global optimization algorithm that uses an attraction-repulsion mechanism to move particles toward optimality. A local search is an important factor influencing the accuracy of the solutions of the EM algorithm. In this paper, we propose a new local search procedure based on Chaos optimization algorithm (COA) to improve efficiency...
Customarily modern procurement adopts a multi-purpose procurement way, so the bid evaluation and contractor selection will be a great problem. The purpose of this paper is to provide a new method to resolve the problem by using regression analysis based on facts-set. This method can evaluation all bids with some cheap computer software. By proving the scientificity of this new method, the author thinks...
