In this paper, we formulate coverage requirements of the sensor network as a minimum-cost connectivity guaranteed point k-coverage problem. An improved ant colony algorithm (EasiDesign) is proposed to achieve the approximate solution to this optimization problem. We made modifications in the convergence strategy and the ant state transition rule of the general ant colony optimization. Considering...
The species conservation technique is a relatively new approach to finding multiple solutions of a multimodal optimization problem. When adopting such a technique, a species is defined as a group of individuals in a population that have similar characteristics and are dominated by the best individual, called the species seed. Species conservation techniques are used to identify species within a population...
The conceptual workflow can be taken as a middle level between the logical specification level and the physical execution level in business workflow system. The conceptual workflow is very important in providing the independency from both the business operational model and the specified implementation platform, so it supports flexible modifications both in the top level and in the bottom level. In...
This paper presents a new approach for substation planning. As more influences of substation on people, society and environment have been concerned, substation planning must be carried out according to the corresponding factors, besides economic cost. Geographical property of substation site is introduced in the consideration, which is denoted to the relationship of the site and its social, economic...
This paper is intended to serve as an introduction to the conceptual design of control system for a compact free electron laser (FEL) terahertz radiation source (FTRS). The general architecture of the control system is presented. The hardware components, software design, communications and subsystems are described in the paper. We also discuss a novel method of using Matlab Simulink\stateflow to simulate...
