Research ArticleOpen accessIn the keywordsFORCED CONVECTION HEAT TRANSFER, FLOW CONFIGURATION AND THERMAL PERFORMANCE IN A SQUARE CHANNEL WITH MODIFIED V-SHAPED BAFFLESAmnart Boonloi, Withada JedsadaratanachaiThe influences of modified V-shaped baffle in a square channel for heat transfer and thermal performance enhancement are presented numerically in three Dimensional (3D). The V-shaped baffles are modified in order to comfortable to installation in the square channel. The plates are used for clamping on both the upper and lower V-shaped baffles resulting the modified V-shaped baffle like orifice … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 7 Apr 2014 · 6,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow and Heat Transfer Profiles in a Square Channel with 45° V-Downstream OrificesWithada Jedsadaratanachai, Amnart BoonloiFlow and heat transfer profiles in a square channel heat exchanger inserted with 45° V-orifices are presented. The influences of Reynolds number (Re = 3000-10,000) and blockage ratio (BR = 0.05, 0.10, 0.15, 0.20 and 0.25) on periodic concepts are investigated numerically. The computational domain is solved with the finite volume method and SIMPLE algorithm. As the numerical results, the … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 18 Nov 2016 · 6,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTUDY OF DYNAMIC MECHANICAL PROPERTIES OF FUSED DEPOSITION MODELLING PROCESSED ULTEM MATERIALAdhiyamaan Arivazhagan, Ammar Saleem, S. H. Masood et al.Fused Deposition Modelling (FDM), a renowned Rapid Prototyping (RP) process, has been successfully implemented in several industries to fabricate concept models and prototypes for rapid manufacturing. This study furnishes terse notes about the material damping properties of FDM made ULTEM samples considering the effect of FDM process parameters. Dynamic Mechanical Analysis (DMA) is carried out using DMA 2980 equipment to … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 19 Aug 2014 · 8,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach of Almost Periodic Lumped Elements Circuits by an Iterative Method Using Auxiliary SourcesMohamed Karim Azizi, Lassaad Latrach, Nathalie Raveu et al.Nowadays, met materials with lumped or distributed elements are emerging and it is necessary to develop new techniques based on the following principles. The approach should be global and have to be formulated according to the existing classic formulations. In fact, the Wave Concept Iterative Process (WCIP) is systematically used in such application. On the other hand, the periodic medium … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 5 Oct 2013 · 6,919 accessesView PDFCite
Research ArticleOpen accessIn the abstractFiber Optic Sensors for Transportation Infrastructural Health MonitoringChin Chang, Rahul MehtaProblem statement: Monitoring the health of transportation infrastructures is currently reliant on transportation maintenance teams. Scheduled and periodic inspections on most of the infrastructures are performed by manual and visual operations, which are generally time consuming and costly procedures. The use of the fiber optic sensor technology makes it possible to realize continuous, real time and automatic health monitoring for … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Characteristics Affecting Agricultural Extension Workers' Job Satisfaction LevelAli Asadi, Fereshteh Fadakar, Zahra Khoshnodifar et al.Problem Statement: One of the closely associated concepts with performance of an organization is job satisfaction. The purpose of this study was to investigate the relationship between personal characteristics and job satisfaction. Approach: A survey of 52 extension workers was conducted in Fars Province, southern Iran. To collect data, a questionnaire including Bray field and Rothe Job Satisfaction Index was … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 8,240 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordREPRESENTING MARKOV CHAINS WITH TRANSITION DIAGRAMSFarida KachapovaStochastic processes have many useful applications and are taught in several university programmes. Students often encounter difficulties in learning stochastic processes and Markov chains, in particular. In this article we describe a teaching strategy that uses transition diagrams to represent a Markov chain and to re-define properties of its states in simple terms of directed graphs. This strategy utilises the … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 17 May 2013 · 7,534 accessesView PDFCite
