Research ArticleOpen accessIn the keywordsMathematical Model Predicting the Critical Heat Flux of Nuclear ReactorsChien-Hsiung Lee, Lih-Wu Hourng, Kuo-Wei LinBoiling heat transfer system keeps a nuclear power plant safe without getting over-heated. Crisis will occur if the dissipated heat flux exceeds the critical heat flux value. This study assumes the flow boiling system at high heat flux is characterized by the existence of a very thin liquid layer, known as the &#34sublayer&#34, which is trapped between the heated surface … …Journal of Computer Science, Vol. 8, Issue 12 · 12 Dec 2012 · 7,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Cluster Head Selection in IoV-Enabled VANETs Using a Federated Diffusion Convolutional Recurrent Neural Networks FrameworkP Subhash, Madana Srinivas, A. Ranjith et al.The IoV enables the formation of VANETs that require a strong selection of CHs for effective communication within high-velocity changing traffic scenarios. Existing approaches often face issues related to scalability, privacy, and adaptability. To meet the aforementioned urgent needs, we design a decentralized scheme for intelligent CH selection based on Federated Learning with Diffusion Convolutional Recurrent Neural Networks (DCRNNs). According … …Journal of Computer Science, Vol. 22, Issue 10 · 1 Oct 2026 · 612 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Climate Factors on the Epidemiology and Management of Potato virus YMahabuba Mostafa, Md. Motaher HossainPlant viruses give rise to potential loss to global crop production and have the potential to cause widespread damage. Potato virus Y (PVY) is a plant virus that belongs to the genus Potyvirus and the family Potyviridae and it is considered a major concern, particularly for solanaceous crops such as potatoes. PVY represents the largest cluster of plant viruses, encompassing … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 Aug 2024 · 4,764 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Gas-Phase Mass Transfer Coefficients in a Humidification Column through Random PackingMasoud Khorasani, Morteza Zivdar, Farshad Fashchi Tabrizi et al.Packed columns are an important part of the broad selection of mass and heat transfer equipment. Nowadays, the use of packed columns is increasing, which is because of its lower pressure drop, higher capacity and higher mass transfer in comparison to tray columns. The experiential tests and the hypothetical analysis display that the chemical dehumidification of air by hygroscopic salt … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Deploying the Flow Guide Vane in Upstream of Triangular Duckbill Weirs on the Efficiency of this Type of Weir in Laboratory ConditionsSayedeh Zahra Hosseini-Teshnizi, Manuchehr Heidarpour, Saeid Eslamian et al.One of the effective ways for the flow of water in low head water conditions is using triangular duckbill weirs. Regarding the high efficiency of these weirs in higher rate of flow discharge in constant head water conditions, the investigation about this type of weirs is greatly required. The present study is done on triangular duckbill weir with two different … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 27 Jun 2019 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Passive Opportunity for Improving Air Quality in the Schools Environment: A Real-World Scale TestingPierpaoli Mattia, Fava GabrieleCan passive technology effectively enhance the indoor air quality? To improve classroom indoor air quality, an increase in ventilation and/or air purifiers are often suggested. In this study, a short-term intervention was implemented and investigated to evaluate the effects of a passive adsorbent surface on the pollutant deposition velocity and to improve the overall classroom air quality. We found that … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 3 Jun 2016 · 7,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy 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 · 7,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinimum 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 · 7,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of the Vertical Dispersion of Pollutants Resulting From Chimneys by Thermosiphon EffectA. O.M. Mahmoud, J. Zinoubi, R. B. Maad, A. BelghithThe dispersion of pollutants, resulting from industrial chimneys, in the surrounding atmosphere made the interest in realizing emitting conditions appears. It also encourages the vertical dispersion of these pollutants. At a given wind velocity, the height of this dispersion is essentially a function of the thermal power and the flow rate at the chimney exit. To improve these qualities, we … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,411 accessesView PDFCite
