Research ArticleOpen accessIn the abstractPOWER QUALITY DIAGNOSIS IN DISTRIBUTION NETWORK USING WAVELET TRANSFORMH. H. Goh, H. L. Ting, Q. S. Chua et al.Power quality is one of the most concerns to the electric power suppliers, equipment manufacturers and the users of various electrical and electronic equipments. This paper presents the use of a continuous wavelet transform to detect and analyse voltage sags and swells. Characteristics which include duration and magnitude of the investigated signals are measured. Unlike other approaches where the detection … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 26 Dec 2013 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPLEMENTATION OF SPACE VECTOR PULSE WIDTH MODULATION TECHNIQUE WITH GENETIC ALGORITHM TO OPTIMIZE UNIFIED POWER QUALITY CONDITIONERM. Shankar, S. Monisha, H. Shesna et al.This study proposes a novel control design of Unified Power Quality Conditioner (UPQC). This design is enabled by a control framework that employs Genetic Algorithm which determines optimum points and angle for filtering and Space Vector Pulse Width Modulation Technique (SVPWM) to offer significant flexibility to optimize waveform. In addition the same framework integrates the major functions of the UPQC … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 14 Dec 2013 · 6,715 accessesView PDFCite

Research ArticleOpen accessIn the abstractDesign and Parametric Optimization of an Organic Rankine Cycle Powered by Solar EnergyFrancesco Calise, Claudio Capuozzo, Laura VanoliThis study presents the simulation and performance analysis of a regenerative and superheated Organic Rankine Cycle (ORC). To this scope, anew simulation model has been developed. The model is based on zero-dimensional energy and mass balances for all the components of the system. Shell and tube heat expanders with single shell and double tube pass have been chosen. Pump and … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 15 May 2013 · 7,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticost Routing Approach in Wireless Ad hoc NetworksD. Loganathan, P. RamamoorthyProblem statement: A Wireless ad hoc network is a collection of autonomous movable nodes that communicate with each other over wireless links without any static infrastructure. In these networks there is no fixed topology because of the mobility of nodes, interference, multipath propagation and path loss. A variety of routing protocols and algorithm with varying network settings are analyzed to … …Journal of Computer Science, Vol. 8, Issue 10 · 30 Aug 2012 · 6,739 accessesView PDFCite
