Research ArticleOpen accessIn the abstractLOW-COST STRATEGIES TO SAVE ENERGY IN K-12 SCHOOLSNabil Nassif, Raymond C. Tesiero III, Harmohindar Singh, K. M. FlurchickAdvanced Energy Management Control Systems (EMCS) offer an excellent means of reducing energy consumption in Heating, Ventilating and Air Conditioning (HVAC) systems while maintaining and improving indoor environmental conditions. This can be achieved through the use of computational intelligence and optimization with a building automation system and multiple sensors, which can be quite expensive. However, energy awareness and proper scheduling … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 17 Mar 2014 · 8,164 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cross-Layered Path Stability Based Routing Protocol for WiMAX NetworksM. Deva Priya, M. L. ValarmathiIn IEEE 802.16, a Subscriber Station (SS) is battery powered with limited capacity. A SS can be made to operate for longer durations by deploying power saving features or by using relay stations. Multi-hop communication conserves power, but finding an optimal path to the destination is monotonous. Path stability indicates how stable a path is and how long it can … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 6,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation of Thermoelectric Generator Modules with Different Technique of Cooling SystemMohd Izam Abd Jalil, Jahariah SampeNowadays the world has experiencing global warming due to excessive energy release into atmospheres. Today, a lot of research being conducted on ways to recover or reused the energy losses. An experimental investigation has been carried out to identify the most suitable cooling system techniques to achieve a stable and sustainable power output. Four types of Thermoelectric Module (TEM) was … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 7 Jan 2013 · 8,217 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Based Plus Integral Controller for PMBLDC Motor Control using Resonant Pole InverterMuruganantham, PalaniPermanent Magnet Brushless DC (PMBLDC) motor drives are increasingly popular in industrial applications due to rapid progress of technologies in power electronics and the growing demand for energy saving. The increasing demand of energy saving from society is the external force for the development of PMBLDC motor drives. It is however driven by a hard-switching Pulse Width Modulation (PWM) inverter, … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 8,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractRealization of Fault Tolerant Routing Protocol for ZigbeeSharmila Sankar, SankaranarayananProblem statement: Increased use of handheld devices and sensor devices pose problems in existing routing protocols. The performance of the existing routing protocols deteriorates very much on these dense scenarios. Control overheads are very important parameter in deciding the performance of routing protocols, which are introduced during route discovery and maintenance process. Denser the network, higher is the control overhead … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractCross-Layer Design for Reducing the Energy Consumption based on Mobility Parameter in DSR for Mobile Ad-Hoc NetworkV. Bhanumathi, R. DhanasekaranProblem statement: The main idea is to design an energy efficient algorithm for reducing the amount of overhearing based on RSS value in a Mobile Ad-hoc Network (MANET). Approach: A cross layer framework is designed by combining the physical, MAC and network layer. RSS value is taken from the physical layer and it is used for finding the Mobility Parameter … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Innovative Farm Scale Biogas/Composting Facility for a Sustainable Medium Size Dairy FarmA.E. Ghaly, M. Al HattabApproach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractCritical Retrospect on Conventional and Luminescent Solar Concentration DevicesHamzah Abdul-Rahman, Chen WangProblem statement: Conventional solar concentrators are only sensitive for the beam radiation and they function poorly in overcast sky conditions. Even under a clear sky condition, trackers are always needed for conventional solar concentrators. Static concentrators always come with a poor concentration rate without a tracker and the light concentrated by normal Luminescent Solar Concentrators (LSC) could not be transported … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 6,930 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntermittent Aeration in Biological Treatment of WastewaterH. Doan, A. LohiProblem statement: E-coating process is widely used to provide a protective coating layer on metal parts in the automotive and metal finishing industry. The wastewater from the coating process contains organic compounds that are used in the cleaning, pretreatment and coating steps. Organic pollutants can be removed biologically. In the aerobic biological treatment, water aeration accounts for a significant portion … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,139 accessesView PDFCite
