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
Research ArticleOpen accessIn the abstractControl Techniques in Heating, Ventilating and Air Conditioning (HVAC) SystemsH. Mirinejad, S. H. Sadati, M. Ghasemian, H. TorabProblem statement: Heating, Ventilating and Air Conditioning (HVAC) systems are among the main installations in residential, commercial and industrial buildings. The purpose of the HVAC systems is normally to provide a comfortable environment in terms of temperature, humidity and other environmental parameters for the occupants as well as to save energy. Achieving these objectives requires a suitable control system design. … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 19,952 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF HIDDEN MARKOV MODEL BASED ADAPTIVE PROVISIONING OF OPTICAL BURST SWITCHING NETWORKS AMENABLE FOR UPGRADATION TO GREEN FLEXIGRID NETWORKSP. G.V. Ramesh, Prita NairCatering to the evolving bandwidth-on-demand applications requires flexible provisioning architectures that ensure fairness to both high end and low end users of internet. Dynamic classification of network paths into long and short, based on traffic dependent connection holding times and a wavelength allocation from different subsets for these categories is a necessity for implementing energy saving hybrid switching, loss recovery … …Journal of Computer Science, Vol. 10, Issue 5 · 16 Jan 2014 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Ionic Liquids in Catholic Coupling of AcetophenonePo-Chung ChengProblem statement: The cathodic coupling of acetophnone was carried out in aqueous solutions containing sodium sulfate and 1-Octyl-3-Methylimidazolium Chloride ([OMIM]Cl) as supporting electrolytes. [OMIM]Cl is an ionic liquid, also serving as a co-solvent to prevent the deposition of products during electrolysis. The products are extracted with ether after electrolyses. Approach: It is shown in this study that the recycling of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Methodology for Designing Radix-2n Serial-Serial MultipliersAbdurazzag Sulaiman AlmiladiProblem statement: The fast growth and increase in complexity of digital and image processing systems necessitate the migration from ad hoc design methods to methodological ones. Methodologies will certainly ease the trade off selection for those systems and shortens the design time. To increase those gained values and expand the searching space more appropriate methodologies need to be developed. Approach: … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,926 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Low Frequencies on Three Phase Induction Motor Performance Operating in Close Proximity to Rated SpeedQazem Jaber, Qais Naman, Mahdi ShamaseenVariable speed drives (VSD) are adhered to induction motors in most of the present industrial applications. And since the world has become more conscientious to energy saving, inverters established them selves in domestic buildings and industry. Square wave inverters generate dominant harmonics of the 5th, 7th, 11th and 13th order. Inverters based on PWM strategy produce much higher harmonic order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,519 accessesView PDFCite
Research ArticleOpen accessIn the abstractDYNAMIC MODELING AND GAIN SCHEDULING CONTROL OF A CHIILLED WATER COOLING SYSTEMJun Liu, M. ZaheeruddinA dynamic model of a Chilled Water (ChW) cooling system with a stratified ChW tank was developed. A PI-based Gain Scheduling (GS) control strategy was designed to improve thermal performance of the chiller system. Five different operation strategies were simulated and the energy consumption and cost of operating the system under full load and partial load conditions were compared. The … …Energy Research Journal, Vol. 5, Issue 1 · 15 Oct 2014 · 7,015 accessesView PDFCite
