Research ArticleOpen accessIn the abstractA Study of Models of Life Quality Development of Isan Marginal Communities as Affected by Installation of the Solar Home SystemPongsil Simvised, Songkoon Chantachon, Sampan RittidechProblem Statement: The electricity production system by using solar home cells is regarded as a substitute for energy which the state provides for the marginal communities because the area cannot be extended for putting up pylons with electric cables, all this for the marginal communities to have better life and being. The purposes of this thesis were to examine the … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Solar Radiation in High Energy Intensive of the World by PV SystemU. Ali RahomaSolar energy can be converted directly into electricity by means of solar cells. Solar cells currently cost around $3.50 per watt for crystalline cells and $2 per watt for thin-film wafers, which are less efficient but can be integrated into building materials. Industry analysts note that between 2000 and 2005, each doubling of cumulative production resulted in a price drop … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Performance of a Solar Heat Storage Accumulator Used For Greenhouses ConditioningMejdi Hazami, Sami Kooli, Meriam Lazaar et al.The use of solar energy for greenhouse heating has gained an increasing acceptance during the last years. Active solar systems applied to greenhouses can supply a significant part of the heating requirements. However, there are some problems related to the cost of the heat collection unit and the heat storage methods. In this context several techniques were born. The most … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware and Software Components of an Oysters' Gape Measurement SystemAmin Ali, Kamal Ali, Aaugustine Ukpebor et al.In this work, the hardware and software used in developing a bivalve gape measurement system is explored. This system employs the Hall-effect phenomenon to accurately measure and report the gape of a bivalve. The system uses a Hall Effect sensor (Symmetry Electronics’ H2425) and a small magnet in which both are glued to the exterior of the shells of a … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 7 Sep 2019 · 8,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractE-Learning System Development using an Open-Source Customization ApproachH. Mohammadi, S. A. Monadjemi, P. Moallem, A. A. OlounabadiEducational organizations have different methods of deploying E-learning systems, of which is using and developing open-source e-learning systems. One should consider some criteria when choosing a suitable system includes: documentation, usage rate, structure, standards support and educational strategy. In this work an e-learning software system has been elected and five phases of modification has been done to domesticate it, which … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Development of a Photovoltaic Power System for Tropical Greenhouse CoolingFaisal Mohammed Seif Al-Shamiry, Desa Ahmad, Abdul Rashid Mohamed Sharif et al.Renewable energy sources like photovoltaic (PV) panels are used today in many applications. Natural ventilation in tropical greenhouse is common method for ventilation, which gives higher inside temperatures compared to the outside temperatures. In addition, this type of ventilation is not enough to reduce high temperature inside the structure in low land areas. Thus the requirement of cooling is increased. … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Near Real-time Early Warning System on Erosion HazardsFaisal H. Ali, Tew K. HuiWith many incidences of landslides, mudslides and erosion occurrences lately, especially in the highlands in Malaysia, properties were damaged and lives were lost. Seeing the need of resolving and minimizing such untoward incidences, a study has been embarked on developing a near real-time early warning system on erosion hazards so as to provide an early warning to the public, whenever … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractManagement of Renewable Energies and Environmental ProtectionRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The purpose of this project is to present an overview of renewable energy sources, major technological developments and case studies, accompanied by applicable examples of the use of sources. Renewable energy is the energy that comes from natural resources: The wind, sunlight, rain, sea waves, tides, geothermal heat, regenerated naturally, automatically. Greenhouse gas emissions pose a serious threat to climate … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Nov 2017 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractOur UniverseRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.It's hard to know ourselves and our role as humanity, without knowing our precise location first. In the universe where we find ourselves (what we know not much about), there are billions of galaxies. A galaxy is a large cluster of stars (suns), i.e., solar systems; on average an ordinary galaxy contains about two billion stars (suns), which may or … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 2 · 21 Jun 2017 · 7,346 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign of a Synchronous Reference Frame Controlled Fuzzy Logic Based Distribution Static Compensator to Enhance Distribution System Power QualityRekha Sampath, Lokesh Mallaiah, Ashwini A V et al.The demand for enhanced power quality in distribution systems has increased due to the widespread utilization of various AC loads, including rectifiers, inductive loads, and variable speed drives. When these nonlinear loads are combined with renewable energy sources, harmonics are introduced in the system. These can affect the way other equipment in the network works and leave the system vulnerable … …Journal of Computer Science, Vol. 22, Issue 2 · 27 Feb 2026 · 1,713 accessesView PDFCite
