Research ArticleOpen accessIn the abstractQUANTUM APPROACH TO THE GRAVITATIONAL WAVESSebastiano TostoThe study proposes a quantum approach to explain existence and main features of the gravitational waves radiated by an isolated two body orbiting system. The quantum eigenvalues of such a system are calculated with the help of the space-time quantum uncertainty, without additional hypotheses via an “ab initio” model. The approach is deliberately non-relativistic: The model does not implement any … …Physics International, Vol. 4, Issue 2 · 6 Jan 2014 · 7,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Wheat Straw Varieties Cultivated Under Different Climatic and Soil Conditions in Three ContinentsYaning Zhang, A. E. Ghaly, Bingxi LiOver 500 million tonnes of wheat straw are produced annually worldwide, the majority of which are burnt in the field causing significant environmental and health problems as well as serious traffic accidents in addition to loss of a valuable resource. Wheat straw is abundantly available and renewable and can be used as an energy source in gasification and combustion systems. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 26 Jun 2012 · 21,096 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Optimized Ad Hoc on Demand Distance Vector Routing Protocol for Wireless NetworksV. Ponniyin Selvan, S. Senthil KumarProblem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis and Overview of Wireless Routing ProtocolsN. Dhanalakshmi, P. AlliProblem statement: In the past, the main focus of the research in the wireless network is to provide optimal routes between source and destination nodes. The wireless routing is required additional computational effort than wired routing in order to fulfill the major wireless characteristics such as battery power constraints, frequent mobility and less processing. Approach: In addition to wired routing … …Journal of Computer Science, Vol. 8, Issue 3 · 17 Jan 2012 · 7,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractA MULTILEVEL CONVERTER WITH REDUCED NUMBER OF SWITCHES FOR FUEL CELL POWER CONDITIONING SYSTEMK. Prasada Rao, Sukhdeo SaoThis study investigates the potentials of cascaded five and seven level converters with reduced number of switches for fuel cell power conditioning system. Fuel cells is one of the most important sources of distributed energy because of its high efficiency, high energy density, plus high reliability and long life due to few moving parts. This study proposes a suitable multilevel … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 11 Apr 2014 · 6,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Congestion Aware Routing Protocol for Mobile Adhoc NetworksG. Rajkumar, K. DuraiswamyProblem statement: The performance of ad hoc routing protocols will significantly degrade when there are faulty nodes in the network. Packet losses and bandwidth degradation are caused due to congestion and thus, time and energy is wasted during its recovery. The fault tolerant congestion aware routing protocol addresses these problems by exploring the network redundancy through multipath routing. Approach: In … …Journal of Computer Science, Vol. 8, Issue 5 · 23 Feb 2012 · 6,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinematic and Dynamic Analysis of a Classic, Three-Axis Manual Gearbox, Without a Direct SocketRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuFixed axis mechanical transmissions today have the largest spread on the entire planet, being practically used in almost all areas. From the gearboxes of the vehicles to the stationary reducers, used in the electrical, electronic and electro technical equipment, in the heavy industry but also in the light industry, in energy and in transport, practically the transmissions with fixed axes … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 24 May 2020 · 7,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Titanium Dioxide Self-Cleaning Coatings on Photovoltaic Modules for Soiling Related Losses ReductionAnnalisa Andaloro, Francesco FrontiniSeveral studies have assessed the influence of soiling deposition on Photovoltaic (PV) modules front-cover with regards to performance losses over time. In fact, soiling phenomena in PV systems are ascribed as responsible for medium and long-term yield reduction up to 16% over the first-year of outdoor exposure. Provided that PV technology is a low yield energy production source, maintaining module … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 5 Feb 2017 · 7,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Heat Transport in a Proton Exchange Membrane (PEM) Fuel CellE. Afshari, S.A. JazayeriIn this study a two-phases, single-domain and non-isothermal model of a Proton Exchange Membrane (PEM) fuel cell has been studied to investigate thermal management effects on fuel cell performance. A set of governing equations, conservation of mass, momentum, species, energy and charge for gas diffusion layers, catalyst layers and the membrane regions are considered. These equations are solved numerically in … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,343 accessesView PDFCite
