Research ArticleOpen accessIn the abstractLow Power Multiplier by Effective Capacitance ReductionNageshwar Reddy Peddamgari, Damu RadhakrishnanIn this study we present an energy efficient multiplier design based on effective capacitance minimization. Only the partial product reduction stage in the multiplier is considered in this research. The effective capacitance at a node is defined as the product of capacitance and switching activity at that node. Hence to minimize the effective capacitance, we decided to ensure that the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 22 Feb 2017 · 7,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Diagnosis of a DC Motor by Bond Graph ApproachAbderrahmène Sallami, Nadia Zanzouri, Mekki KsouriIn this article, a Bond Graph (BG) approach is used for modeling, simulation and robust diagnosis of a DC Motor. The design and calculation of an observer is achieved by using graphical methods taking advantage of the structural properties of bond graph model. Simulation results are used to show the dynamic behavior of the system variables and assessing the performance … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 17 Jun 2016 · 8,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrophysical Characterization and Flow Models for Agbada Reservoirs, Onshore Niger Delta, NigeriaPrince Suka Momta, John Owate Etu-Efeotor, Charles Ugwu UgwuezeThree selected reservoirs (XB, XC and XE) from three wells (A, B and C) occurring within the Agbada producing sands in part of the Greater Ughelli Depobelt of the onshore Niger Delta have been studied. The study aims at evaluating the petrophysical characteristics of the sand-bodies and also identifies the various flow units present within each reservoir. Petrophysical parameters were … …Current Research in Geoscience, Vol. 5, Issue 2 · 21 Oct 2015 · 7,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING QUALITY OF SERVICE IN MOBILE ADHOC NETWORKS FOR PROACTIVE AND REACTIVE PROTOCOLS USING GENETIC ALGORITHMM. Pushpavalli, A. M. NatarajanNow-a-days finding a path from source to destination for practical multimedia applications by satisfying the QoS requirement is a big challenge. Achieving quality of service in a mobile adhoc network is an NP complete problem due to its dynamic nature of the network and limited resource availability. In this study, we propose a new QoS module which uses genetic algorithm … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 9 Sep 2014 · 6,399 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE HIGH VOLUME REUSE OF HYBRID BIOMASS ASH AS A PRIMARY BINDER IN CEMENTLESS MORTAR BLOCKCheah Chee Ban, Noor Shazea Ahmad Nordin, Part Wei Ken et al.High Calcium Wood Ash (HCWA) and Pulverised Fuel Ash (PFA) are by-products from the wood biomass and coal energy production which are produced in large quantity with combined annual production of 500 million tonnes. This poses a serious problem for disposal of the waste material especially at places where land is scarce. The prescribed study was aimed to examine the … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOMPARISON OF OPTIMIZATION TECHNIQUE TO FIND THE OPTIMAL LOCATION OF FACTS CONTROLLERS FOR TRANSMISSION LINEJagadeesh Kumar Muthukrishnan, Subhransu Sekhar Dash, Harish Kiran Selvakumar et al.The aspect of this study is to compare the three different algorithms such as Genetic Algorithm (GA), Enhanced Genetic Algorithm (EGA) and Particle Swarm Optimization (PSO) to fine the optimal location of the FACTS device in the transmission line. The FACTS devices Thyristor Controlled Series Compensator (TCSC) and Unified Power Flow Controller (UPFC) are selected based on the steady stability … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 26 Dec 2013 · 6,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractFire Design: Direct Comparison Between Fire Curves. The Case Study of a NurseryMara Lombardi, Giuliano Rossi, Nicolò Sciarretta, Nino OrangesAccording to fire safety engineering, the present study analyzes fire design settings for simulation of fire in a nursery and proposes to compare simulations developed with a natural fire curve and nominal fire curve. Comparative analysis was developed according to thermo-fluid dynamic parameters that are relevant to the safety of the exposed and for the representative period of the danger … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 9 Sep 2013 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractPriority Based Congestion Detection and Avoidance in Wireless Sensor NetworksR. Beulah Jayakumari, V. Jawahar SenthilkumarThe primary objective of event driven wireless sensor networks is to route the detected or monitored data at the earliest to the base station depending on their degree of priority since the data generated in a sensor network has different importance. In order to avoid indiscriminate dropping of data during congestion we propose a novel congestion protocol named priority based … …Journal of Computer Science, Vol. 9, Issue 3 · 26 Apr 2013 · 6,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVIDENCE OF THE ENVIRONMENTAL KUZNETS CURVE: IMPLICATIONS OF INDUSTRIAL TRADE DATAJamalludin Sulaiman, Azlinda Azman, Behnaz SabooriThis study examines the dynamic relationship between CO2 emissions and economic growth in Malaysia for the period of 1980-2004. The evidence of the Environmental Kuznets Curve (EKC) is tested by including energy consumption, dirty export from Malaysia to China and dirty import from China to Malaysia based on the two and three-digit ISIC data which reflect pollution-intensive manufacturing. Using dirty … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 26 Mar 2013 · 7,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Zones of Peruvanthanam and Valiyathodu Sub-Watersheds of Manimala River BasinVadakkepurakkal Rekha, Aikara Varkey George, Rita MendezGroundwater is a dynamic and replenishable natural resource. But in hard rock terrains, its availability is of limited extent. In sub-watershed studies, remote sensing and GIS techniques have the advantages of spatial, spectral and temporal data, covering large and inaccessible areas within a short span of time. Thus this technique has become a very handy tool in assessing and monitoring … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 20 Feb 2013 · 7,396 accessesView PDFCite
