Research ArticleOpen accessIn the abstractENERGY EFFICIENT FLOW AND LEVEL CONTROL IN A HYDRO POWER PLANT USING FUZZY LOGICA. Selwin Mich Priyadharson, M. S. Saravanan, N. Gomathi et al.The main objective and an innovative design of this work is to improve the energy efficiency by controlling the variables flow and level in a hydroelectric power plant using Programmable Logic Control (PLC)-Human Machine Interface (HMI) and fuzzy logic approach. This project will focus on design and development of flow and level controller for small scale hydro generating units by … …Journal of Computer Science, Vol. 10, Issue 9 · 19 Apr 2014 · 6,814 accessesView PDFCite
Research ArticleOpen accessIn the abstractWIRELESS SENSOR NETWORKS FOR MEASURING THE CONSUMPTION OF SAVE WATER TAPSInacio Henrique Yano, Vitor Chaves de Oliveira, Eduardo Veiga de Araujo et al.Currently, water consumption is on the agenda of most organizations around the world. Beyond the environmental benefits for a better use of natural resources there is also a financial motivation to continuously reduce operation costs. This study reports a cost-effective solution using a Wireless Sensor Network (WSN) for measuring the consumption of different types of save water taps, in a … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 1 Apr 2014 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmbedded Computer Based Active Vibration Control System for Vibration Reduction of Flexible StructuresVenkata Ratnam Tatavolu, Seetha Ramaiah PanchumarthyResearch on Active Vibration Control System (AVCS) is being carried out to reduce structural vibrations caused by unwanted vibrations in many application areas such as in space, aircraft structures, satellites, automobiles and civil structures (bridges), particularly at low frequencies. The unwanted vibration may cause damage to the structure or degradation to the structure’s performance. The AVCS comprises physical plant, a … …Journal of Computer Science, Vol. 9, Issue 7 · 15 Jun 2013 · 6,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation of Fuzzy Logic Maximum Power Point Tracking Controller for Photovoltaic SystemRasoul Rahmani, Mohammadmehdi Seyedmahmoudian, Saad Mekhilef, Rubiyah YusofIn this study, simulation and hardware implementation of Fuzzy Logic (FL) Maximum Power Point Tracking (MPPT) used in photovoltaic system with a direct control method are presented. In this control system, no proportional or integral control loop exists and an adaptive FL controller generates the control signals. The designed and integrated system is a contribution of different aspects which includes … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 5 Mar 2013 · 7,870 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Diffusion Coefficient using Reversed-Flow Gas Chromatography-A ReviewKhalisanni Khalid, Rashid Atta Khan, Sharifuddin Mohd. ZainProblem statement: Since the earliest publication on the technique, Reversed-Flow Gas Chromatography (RF-GC) has been used to determine physicochemical properties by measuring the value of one in the presence of another. The method is precise, accurate and simple compared to other conventional techniques. Approach: The experimental setup consists of a small modification of a commercial gas chromatograph, so that it … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractVoltage Swells Improvement in Low Voltage Network Using Dynamic Voltage RestorerR. Omar, N.A. Rahim, A. AhmadProblem statement: Voltage disturbances are the most common power quality problem due to the increased use of a large numbers of sophisticated electronic equipment in industrial distribution system. The voltage disturbances such as voltage sags, swells, harmonics, unbalance and flickers. High quality in the power supply is needed, since failures due to such disturbances usually have a high impact on … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Predator Go for Size Selection or Preferential Toxic-Nontoxic Species Under Limited Resource?Joydeep Pal, S. Bhattacharya, J. ChattopadhyayProblem statement: Selectivity is common in predator-prey interaction but the selection mechanism is still unexplored and a debatable issue in modern theoretical and experimental ecology for numerous species across the globe. In present investigation we emphasized the hypothesis that the zooplankton is less inclined to opt the food based on size selectivity criteria than the preferential selectivity for the safe … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingle Beam Z-Scan Measurements of Nonlinear Refraction and Nonlinear Absorption Coefficients in Silver Nano-FluidEsmaeil Shahriari, W. Mahmood Mat YunusProblem statement: The nonlinear refractive index and nonlinear absorption are two important optical phenomena which are extensively used in optical switching, optical limiting and labeling. Approach: In the present research we had measured nonlinearity of Ag nano-fluid prepared using γ-irradiation method. The measurement was carried out using a single beam z-scan technique. Under a CW laser beam excitation operated at … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New System to Analyze Pulsatile Flow Characteristics in Elastic Tubes for Hemodynamic ApplicationsAfshin Anssari-Benam, Mohammad Tafazzoli-Shadpour, Nasser Fatouraee et al.In this research, we present a new designed experimental setup for study of characteristics of pulsatile flow in elastic tubes, aiming to simulate arterial blood flow. This system includes four major components: (1) a pulsatile pump producing original arterial flow, (2) an elastic element to simulate coupling of the heart with the arterial system, (3) an elastic tube with mechanical … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Speech Features on the Speech Recognition TaskIosif Mporas, Todor Ganchev, Mihalis Siafarikas, Nikos FakotakisIn the present work we overview some recently proposed discrete Fourier transform (DFT)- and discrete wavelet packet transform (DWPT)-based speech parameterization methods and evaluate their performance on the speech recognition task. Specifically, in order to assess the practical value of these less studied speech parameterization methods, we evaluate them in a common experimental setup and compare their performance against traditional … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Dec 2007 · 7,117 accessesView PDFCite
