Research ArticleOpen accessIn the abstractBackscattered Acoustic Energy by Monobubbles Experimental Approach and Statistical Study of the AttenuationAli Khelil, Claude ManteProblem statement: As the number of air bubbles in the sea is very high, they are so many acoustic diffusers who make illegible the recordings the purpose of which is to quantify the alive bodies. The signals backscattered by air bubbles constitute a parasite in offshore recordings and must be eliminated. It is planned to finalize techniques allowing the localization … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,585 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 abstractA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New System to Analyze Pulsatile Flow Characteristics in Elastic Tubes for Hemodynamic ApplicationsAfshin Anssari-Benam, Mohammad Tafazzoli-Shadpour, Nasser Fatouraee et al.In this research, we present a new designed experimental setup for study of characteristics of pulsatile flow in elastic tubes, aiming to simulate arterial blood flow. This system includes four major components: (1) a pulsatile pump producing original arterial flow, (2) an elastic element to simulate coupling of the heart with the arterial system, (3) an elastic tube with mechanical … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Flow Structure of A Thermal Plume Evolving in an Unlimited and in A Semi-Enclosed EnvironmentJamil Zinoubi, A. Ould Mohamed Mahmoud, Taoufik Naffouti et al.The basic objective of this study was to better knowledge the fine flow structure of thermal plume created by a heated disk, evolving in an unlimited and in a semi-enclosed environment. The flow visualization and the study of the temperature fluctuations spectrum show clearly a considerable change of the turbulent structure of the internal flow in comparison with the free … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Energy Loss in the Steam Valves and its EffectsGalip Temir, Durriye BilgeIn this study, the effects of thermal losses in steam valves for flow have been analyzed. In a set of experiment built to achieve this, pressure and condensate values have been calculated in different temperatures for insulated and non-insulated cases in three different nominal diameter steam valves. The amount of energy lost from the valve surface in the natural convection … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Dynamic Simulation of a Combined System Integration Concentrating Photovoltaic/Thermal Solar Collectors and Organic Rankine CycleFrancesco Calise, Massimo Dentice d'Accadia, Maria Vicidomini et al.This study presents the design of a novel ultra-high efficient solar power system. The system is equipped with a concentrating PhotoVoltaic/Thermal (CPVT) solar collectors bottomed by an Organic Rankine Cycle (ORC). The basic idea is to use a high temperature CPVT device producing simultaneously electricity and hot diathermic oil. Then, this hot fluid is used to supply heat to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 17 Apr 2015 · 8,659 accessesView PDFCite
Review ArticleOpen accessIn the abstractHybrid Photovoltaic/Thermal (HPV/T) Systems: From Theory to ApplicationsErdem Cuce, Erman Kadir Oztekin, Pinar Mert CuceHybrid photovoltaic/ thermal systems are very promising clean energy harvesting devices where they can be used either standalone system or can be incorporated with other systems. In this study, historical developments leading to current Hybrid Photovoltaic/Thermal (HPV/T) systems as it is used today and global findings to enhance the performance of HPV/T system through state-of-the-art analyses are presented in a … …Energy Research Journal, Vol. 9, Issue 1 · 29 Jun 2018 · 7,877 accessesView PDFCite
Technical ReportOpen accessIn the abstractSmall Hard Body Impact on Annealed, Heat Strengthened and Fully Tempered Laminated GlassFred Veer, Ton Romein, Pim BuskermolenNeglecting the accidental soccer or golf ball hitting the window of the neighbors in a movie, actual impact on glass is rare. In architecture, the only significant case in the literature is where a fully tempered laminated panel of the New York Apple cube was hit by a small stone launched by a snow blower. Nowadays a lot of glass … …International Journal of Structural Glass and Advanced Materials Research, Vol. 6, Issue 1 · 13 Jul 2022 · 10,568 accessesView PDFCite
