Cholesterol level is the significant factor which causes cardiovascular disease. The cholesterol types used to measure the fat level are total, low density lipoprotein (LDL), high density lipoprotein (HDL) and Triglycerides (TG). There are two methods used to measure the cholesterol level. The first method is by directly measuring the patient blood which although yields the best accuracy, is accompanied...
Selecting k out of a given set say n of sensors to accomplish some tasks or meet some well-defined objectives is often modelled and solved as an optimization problem or through an exhaustive search. The later solution strategy is ideal for some small sizes of both n and k. However, this simplistic method becomes quite hard and resource intensive considering a network of randomly deployed wireless...
This paper presents an optimization model of the power generation potential for either new or repowered hydroelectric plants. It is based on curves that represent the unit efficiency as a function of the nominal output. The objective is to choose the combination of efficiency curve types that maximizes the power generation for certain load levels. The mathematical formulation results in a mixed integer,...
This paper deals with a reliability optimization problem for a series system with multiple-choice and budget constraints. Choosing one technology for each subsystem and for maximizing the reliability of the whole system subject to the available budget, the optimization criteria are in used. We develop an efficient genetic algorithm hybridized with a local search step to solve the problem. In the approach,...
Mutation is a fundamental operation in genetic algorithm (GA) for it has a significant impact on global search ability and convergence rate. Traditional mutation operation of GA changes chromosomes randomly (or blindly), which would waste a lot of computational cost in searching less promising regions or those have been searched frequently. To address these drawbacks, this paper proposes a novel guide...
