Research ArticleOpen accessEvery word in the titleTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproving Routing Discovery Based Velocity-Aware Probabilistic Using AODV with Link Prediction in Mobile Ad-hoc NetworksZaid BassfarThe current process associated with enhancing the QoS in routing for MANETs has reserved a high importance due to the limitation of available route discovery in dynamic topology. The conventional methods of route discovery schemes in MANETs are commonly designed in order to estimate the number of nodes in routes using the standard probabilistic models. Such models are utilized by … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 1 Aug 2017 · 7,655 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFuzzy Velocity Biased-Ad Hoc on Demand Distance Vector to Improve Throughput in Dynamic Mobile NetworkK. Tamizarasu, M. RajaramProblem statement: With the escalating demand for mobile ad hoc network projects, major challenges to system planners and designers were addressing stability and reliability problems due to frequent change of network topology. Controlling an overhead, which means bandwidth utilization due to control packets, depends on the routing protocol, topology and data traffic. Limiting the network control overheads, of this highly … …Journal of Computer Science, Vol. 8, Issue 2 · 21 Nov 2011 · 7,056 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part II: Characteristic Velocity Profiles, Critical Loading and Binary CorrelationsV. S. Chok, A. Gorin, H. B. ChuaProblem statement: In Part I of this research, the main features of the fluidization behavior and characteristic velocities had been reported. Approach: In the present research, the mixtures characteristic velocity profiles for various sand sizes, palm shell sizes and weight percents were presented. It was recognized that there are instances where the characteristic values remain nearly unchanged from its pure … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,423 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation of C*-Integral for Radial Cracks in Annular Discs under Constant Angular Velocity and Internal PressureA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral for single and double-edge cracks in eight annular rotating discs under constant angular velocity with and without internal pressure. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power law creeping finite element analyses have been performed and the results are … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,721 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysical Characterizations of Sands and Their Influence in Fall VelocityRuiz-Martinez Gabriel, Mendoza-Baldwin Edgar, Silva-Casarín RodolfoCancun beach is one of the most important tourist resorts on the Mexican coast, and is of prime importance to the local and national economies. As a result of the intense use of the beach and the unavailability of sand reserves, the extreme weather events that occur in the region (hurricanes) have permanently damaged the beach. Over the last two … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,460 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Method for Transmitting Spacecrafts in Space with Velocity of at Least 0.01 of the Light Speed Using Materials with Very High Kinetic Energy in High Electric FieldsMario Nady AiadMany space new missions are on calendar this decade for Moon, Mars and other planets. Some of these missions are depending on simple reliable chemical thrusters and others on the nonchemical advanced propulsion techniques. In most of nonchemical techniques a nuclear source of energy is necessary as in nuclear electric rockets where the maximum velocity produced is around 20 km/s. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 22 Dec 2023 · 5,365 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Handwriting Velocity to Identify Handwriting Process from Electromyographic SignalsMohamed Benrejeb, Afef Abdelkrim, Ines ChihiProblem statement: Handwriting movement is one of the most complex activities of human motions. It’s a blend of kinesthetic, cognitive, perceptual and motor components. The study of this biological process shows that a bell-shaped velocity profiles are generally observed in the handwriting motion. We, therefore, assume that the handwriting speed has an important role in control and generation of this … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 27 Aug 2012 · 7,917 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Gas Velocity and Temperature on Nitric Oxide Conversion in Simulated Catalytic ConverterSathaporn ChuepengProblem statement: Gaseous emissions from gasoline engine such as carbon monoxide, unburned hydrocarbon and nitrogen oxides were usually reduced in three-way catalytic converter simultaneously around theoretical fuel and air combustion. Engine speed and load and other parameters were varied over a wide range of operating conditions, resulting in different exhaust gas composition and condition intake into catalytic converter. This work … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 27 Jun 2012 · 7,304 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part I: Fluidization Behavior and Characteristic VelocitiesV. S. Chok, A. Gorin, H. B. ChuaProblem statement: Palm shell on its original state cannot be fluidized solely. However, mixing palm shell with a second fluidizable material can facilitate proper fluidization. Approach: The minimum and complete fluidization velocity (Umf and Ucf) for sand/palm shell binary mixtures had been studied in a partitioned reactor known as Compartmented Fluidized Bed Gasifier (CFBG). The pilot scale reactor ID is … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,214 accessesView PDFCite
