Under the smart grid environments, Demand Response Resources (DRRs) as power system resources can effectively participate in and improve performance of electric systems. Congestion management is one of the technical challenges in which DRRs can play a significant role. Previously, congestion management is applied without considering the power system uncertainties. Therefore, a stochastic conges...

Several traditional stopping criteria in Genetic Algorithms (GAs) are applied to the optimization process of a typical laminated composite plate. The results show that neither of the criteria of the type of statistical parameters, nor those of the kinds of theoretical models performs satisfactorily in determining the interruption point for the GA process. Here, considering the configuration of ...

The history of research on the development of program-families is briefly reviewed. Two distinct problems, configuration-management and family-design are identified. It is explained that, while software configuration-management is not fundamentally different from configurationmanagement for other products, in practice, inadequate attention to family-design exacerbates all problems associated wi...

In multi-axis machine tool systems, the configuration of system gains and the coordination of redundant degrees of freedom are often a problem of insurmountable difficulty. This study explores the use of a nontraditional scheme, the genetic algorithm, in the configuration of system gains and exploitation of redundant degrees of freedom. The off-line gains configuration functioned as a kind of s...

This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five resistors is selected and optimized based on Quasi Newton method. Then the Defected Microstrip Structure (DMS) and Defected Ground Structure (DGS) is used to obtain better tra...

Creating a valid software configuration of a product line can require laborious customizations involving multiple configuration file types, such as feature models, domain-specific languages, or preprocessor defines in C header files. Using configurable off-the-shelf components causes additional complexity. Without checking of constraints across file types boundaries already at configuration tim...

Abstract In parallel with the industry 4.0 revolution, customers’ demand and number of product requirements are increasing, inducing increased variability. System complexity is growing new technologies system architectures. Hence, maintaining a consistent in desired state becomes crucial. This paper tackles two problems: product's variability its temporal evolution. Regarding variability, Model...

Several studies on photovoltaic systems focused on how it operates and energy required in operating it. Little attention is paid on its configurations, modeling of mean time to system failure, availability, cost benefit and comparisons of parallel and series–parallel designs. In this research work, four system configurations were studied. Configuration I consists of two sub-components arranged ...
