Research ArticleOpen accessAll words, across the recordPreliminary Experimental and Finite-Element Numerical Assessment of the Structural Performance of SMA-Reinforced GFRP SystemsFilipe Amarante dos Santos, Chiara BedonIn this study, the feasibility and potentiality of a novel design concept is explored by means of small scale experimental tests and Finite-Element numerical simulation. Taking advantage of the intrinsic potentiality of Shape-Memory Alloys wires able to work as adaptive actuators when subjected to joule heating, a 'smart-GFRP' concept consisting in Glass-Fiber-Reinforced-Polymer (GFRP) structural members with a SMA reinforcement is … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,289 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAssessing Convergence of the Markov Chain Monte Carlo Method in Multivariate CaseDenismar Alves Nogueira, Thelma Safadi, Daniel Furtado Ferreira, Eric Batista FerreiraThe formal convergence diagnosis of the Markov Chain Monte Carlo (MCMC) is made using univariate and multivariate criteria. In 1998, a multivariate extension of the univariate criterion of multiple sequences was proposed. However, due to some problems of that multivariate criterion, an alternative form of calculation was proposed in addition to the two new alternatives for multivariate convergence criteria. In … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 8 Jan 2013 · 7,019 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign of Field Programmable Gate Array Based Emulators for Motor Control ApplicationsAhmed Ben Achballah, Slim Ben Othman, Slim Ben SaoudProblem statement: Field Programmable Gate Array (FPGA) circuits play a significant role in major recent embedded process control designs. However, exploiting these platforms requires deep hardware conception skills and remains an important time consuming stage in a design flow. High Level Synthesis technique avoids this bottleneck and increases design productivity as witnessed by industry specialists. Approach: This study proposes to … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 12 Jun 2012 · 8,723 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAdaptable User Interface Based on the Ecological Interface Design Concept for Multiple Robots Operating Works with UncertaintyHiroshi FurukawaProblem statement: When supervising a team of semi-autonomous robots, the operator’s task is not only the manipulation of each robot but also achievement of the top goal that is assigned to the entire team of humans and robots. The operators are demanded to comprehend highly complex states and make appropriate decisions in dynamic environment using the limited cognitive resources. The … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,196 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordError Resistant Real-Time Transport Control ProtocolS. Shahbazi, K. Jumari, M. IsmailProblem statement: Real-time Transport Control Protocol (RTCP) protocol has been the subject of various criticisms due its problematic performance in large-scale networks. S-RTCP is a protocol with high potential as it has proved to be able to solve many problems of RTCP. It has numerous flaws on its own. This study aimed at dealing with flaws of S-RTCP and improving … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,087 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordSimulation of Convective Heat-Transfer Coefficient in a Buried ExchangerTaoufik Mnasri, Rached Ben Younès, Maher Raddaoui, Salem ElouraginiThis study presents analytical models allowing to study a forced convection laminar flow in non-established dynamic and thermic regimes. We treated a flow in a bitubular exchanger in permanent thermal contact with a semi-infinite medium, such as the ground. The wall temperature as well as the wall heat flux evolve in the course of time until a quasi-steady mode. The … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,901 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGeneralized Shortest Path Problem in Uncertain Environment Based on PSOHayder A. Mukhef, Ekhlas M. Farhan, Mohammed R. JassimGeneralized network problems describe situations in which flow can be generated or consumed through arcs. This research considers generalized shortest path problem in stochastic environment in which the changing rate of flow is random. To satisfy the demands of decision makers, three types of models have been formulated to solve the generalized shortest path problem under different decision criteria. The … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,749 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPerformance Analysis of a 32-Bit Multiplier with a Carry-Look-Ahead Adder and a 32-bit Multiplier with a Ripple Adder using VHDLHasan Krad, Aws Y. Al-TaieThis study presents a performance analysis of two different multipliers for unsigned data, one uses a carry-look-ahead adder and the second one uses a ripple adder. The study's main focus is on the speed of the multiplication operation on these 32-bit multipliers which are modeled using VHDL, A hardware description language. The multiplier with a carry-look-ahead adder has shown a … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,385 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRarefied Gas Flow Modeling inside Rotating Circular CylinderN. PourmahmoudIn this study a rarefied gas flow inside a rotating circular cylinder by means of direct simulation Monte Carlo (DSMC) method is investigated. A rarefied gas is supposed to be contained in a cylindrical domain, bonded by a rotational cylinder with smooth and diffuse-reflection surface. The top and bottom ends of domain is assumed to be speculary-reflecting.
