Research ArticleOpen accessIn the abstractEvaluation of Single-Pass Photovoltaic-Thermal Air Collector with Rectangle Tunnel AbsorberGoh Li Jin, Adnan Ibrahim, Yee Kim Chean et al.Problem statement: Photovoltaic solar cell generate electric by receiving sun light or solar irradiance. But solar cell received heat from solar irradiance as well and this will reduced the efficiency of the solar cell. The heat trap at the solar photovoltaic panel become waste energy. Approach: The solution for this was by adding a cooling system to the photovoltaic panel. … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical and Magnetoresistive studies Nd doped on La-Ba-Mn-O3 Manganites for Low-field Sensor applicationH. Abdullah, S. A. HalimProblem Statement: Electrical and magnetoresistive properties of the Nd doped (La1-xNdx)0.5Ba0.5MnO3 type samples with 0 ≤ x ≤ 1.0 had been prepared using the solid state reaction. These materials are extensively studied by the substitution of rare-earth compound is to understand the nature of transport phenomena in each system. Approach: The samples were calcined at 900°C for 12 h, pelletized … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of the Electric Power Quality and Electrical Installation Impacts on Medical Electrical Equipment Operations at Health Care FacilitiesMário César Giacco Ramos, Carlos Márcio Vieira TahanProblem statement: Medical electrical equipments at health care facilities presented malfunction and wrong medical information due to poor electric power quality and to inadequate electrical Installations. Some equipment such as X-ray, computerized axial tomography and magnetic resonance imaging are considered as polluting ones due to their high amount of harmonics and voltage transients produced on the electrical power supply when … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,517 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Applied Research Program on Water Desalination with Renewable EnergiesSergio M. Alcocer, Gerardo HiriartThe use of renewable energy for desalination might be quite different in many places of the world. In Mexico, specifically in Baja California, there is an abundance of "traditional" renewable resources like sun and wind but also some others like hot springs at the coast, tidal currents and tidal amplitudes of over six meters in the upper part of the … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Wireless Electric Concept Powering Electrical AppliancesHanita Daud, Noorhana Yahya, Azizuddin A. Aziz, Mohd Fadzzrul JusohThis study presents a concept of harvesting and transferring energy to a low power electrical appliances using wireless technology where interconnecting wires are not available. This study was a ground work for the future alternative energy supply especially to the areas where supplying direct energy is a challenge such as in deep sea exploration as well as to the area … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,343 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
