Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from...

This paper constructs a general class of two-point optimal fourthorder methods without memory for locating multiple roots of a nonlinear equation. On the basis of Kung-Traub’s conjecture, we investigate the optimal convergence as well as computational properties for the class. Explicit forms of asymptotic error constants are presented to strongly verify the convergence order. A variety of numer...

For independent global constraints Web services composition problem, it is difficult to analyze the optimal composition plan. The study presents an optimization method of Web service composition with constraint using Fuzzy Petri Net (FPN) and Differential Evolution (DE), which can transforms solving the optimal service composition problem into locating the largest trust value of legal firing se...

Industrial robots driven electrically with a feedback control loop (and even then hydrauhcally) create highly nonlinear dynamic systems, the control of which in real time is a difficult problem of the control theory. From the theoretical point of view it is a classical problem of optimal control. A system is to be controlled from the initial state to the terminal state so as to minimize some pe...

The success of softwaredevelopment using thirdparty components highly depends on the ability to select a suitable component for the intended application. The evidence shows that there is limited knowledge about current industrial OTS selection practices. As a result, there is often a gap between theory and practice, and the proposedmethods for supporting selection are rarely adopted in the indu...

An analysis of the results of an algorithm for optimal trajectory planning of robot manipulators is described in this paper. The objective function to be minimized is a weighted sum of the integral squared jerk and the execution time. Two possible primitives for building the trajectory are considered: cubic splines or fifth-order B-splines. The proposed technique allows to set constraints on th...

Process control should aim at not only ensuring that controlled variables to best follow their set points, but also requiring the optimal control for the operation of the whole plant to make the operational indices (e.g. quality, efficiency and consumptions during the production phase) into their targeted ranges. It also requires that operational indices for quality and efficiency should be enh...

Water quality monitoring network design has historically tended to use experience, intuition and subjective judgement in locating monitoring stations. Better design procedures to optimize monitoring systems need to simultaneously identify significant planning objectives and consider a number of social, economic and environmental constraints. The consideration of multiple objectives may require ...
