Research ArticleOpen accessIn the abstractContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Control of Three-Phase Shunt Active Power FilterMoleykutty George, Kartik Prasad BasuIn this research the performance of a three-phase shunt active power filter (APF) using Model Reference Controller (MRC) has been compared with that using instantaneous active and reactive (p-q) theory. The novelty of this research lies in the application of MRC to generate the amplitude of the reference supply current required by the APF circuit and the successful implementation of … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree-Phase Shunt Active Power FilterMoleykutty George, Kartik Prasad BasuActive power filters have been widely used for harmonic elimination. The performance of a conventional three-phase shunt Active Power Filter (APF) using Synchronous Detection Method (SDM) has been compared with Nonlinear Autoregressive-Moving Average (NARMA)-L2 based APF. The novelty of this study lies in the application of NARMA-L2 control to generate the amplitude of the reference supply current required by the … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Simulation of a Novel Switched Reluctance Motor Drive System with Power Factor ImprovementG. Venkatesan, R. Arumugam, M. Vasudevan et al.This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fully Integrated Dual-Band Low Noise Amplifier for IEEE 802.11 and Hiper LAN ApplicationMow Shouxian, Ma Jianguo, Yeo Kiat Seng, Do Manh AnhA fully-integrated dual-band Low Noise Amplifier (LNA), which can be used for IEEE 802.11 and Hiper LAN applications, was investigated in this paper. The proposed LAN was implemented entirely pm a single chip based on a standard 0.18 μm 1P6M CMOS process. It draws 13 mA current from a 1.5-V voltage supply and achieves power gains of 17 and 10 … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,291 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-Time Data Capture Model for Accelerated Payment of Small-Scale FarmersNatasha Mwansa, Jackson PhiriMost developing countries especially in Africa face a number of challenges in the area of food security. These challenges include proliferation, theft, poor inventory system, poor transport and communication network. Zambia is one of the countries with these challenges and has been losing millions of dollars each year due to various challenges in managing the inventory system. In this paper, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 29 Sep 2018 · 7,105 accessesView PDFCite
Review ArticleOpen accessIn the abstractArchitecture of Ultra Low Power Micro Energy Harvester Using RF Signal for Health Care Monitoring System: A ReviewFarah Fatin Zulkifli, Jahariah Sampe, Muhammad Shabiul Islam, Mohd Ambri MohamedThis research presents architecture of Ultra Low Power (ULP) Micro Energy Harvester (MEH) using Radio Frequency (RF) signal as an input. RF has many advantages compared to other ambient sources because it is not affected by changes of weather or time, does not require heat or wind exposure and it can be moved randomly within the bound of the transmission … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 7 Jul 2015 · 6,961 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,424 accessesView PDFCite
