Research ArticleOpen accessIn the abstractModeling and Control of a Photovoltaic Energy System Using the State-Space Averaging TechniqueMohd Saifuzam Jamri, Tan Chee WeiProblem statement: This study presented the modeling and control of a stand-alone Photovoltaic (PV) system using the state-space averaging technique. Approach: The PV module was modeled based on the parameters obtained from a commercial PV data sheet while state-space method is used to model the power converter. A DC-DC boost converter was chosen to step up the input DC voltage … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 7,997 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl 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

Research ArticleOpen accessIn the abstractThe Investigation of Biological Nitrogen Fixation in Critical Dryland PastureSyamsuddin Hasan, Budiman, Asmuddin Natsir et al.The aim of the study is to determine the production and growth of dwarf napier grass (Pennisetum purpureum cv.mott) integrated with siratro legumes (Macroptilium atropurpureum) contributing to the availability of preferred forage for ruminants on critical dryland. The study applied randomized block design consisted of 4 groups and 4 treatments; P0 consisted of 100% control Pennisetum purpureum cv.mott; P1 consisted … …OnLine Journal of Biological Sciences, Vol. 19, Issue 3 · 26 Jul 2019 · 7,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial-Temporal Analysis of Temperature Trend and its Possible Effects on Water Resources and Water Uses in Climatic Zones of Iran's Zayandehrud River BasinAli Hasantabar-Amiri, Kaveh Ostad-Ali-Askari, Ali Heidarian et al.The minimum, moderate and maximum temperature trends at seasonal time scale in 5 climatic zones using 37 meteorological stations in Zayandehrud river basin was studied regionally and the relationship to water resources, water uses of each zone and its possible effects were determined. The results showed that the majority of the climatic zones will have an increasing trend in spring, … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 27 Jun 2019 · 8,045 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Low Emission Development: Prospects of Applying MBIs in the Industrial Sector of Central Java, IndonesiaAgung Sugiri, Imam BuchoriIn dealing with pollution or emission, including in encouraging Low Emission Development (LED) as an acceptable strategy for climate change mitigation, Indonesia applies Command and Control (CAC) approach through regulations on environmental and pollution standards. However, the enforcement is characterized by weak monitoring and controlling due to aspects like non-compliant industries and lack of personnel and equipment of the corresponding … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 11 Jun 2016 · 8,196 accessesView PDFCite
