Research ArticleOpen accessEvery word in the titleThree Dimensional Hydrodynamic Model With Multiquadtree MeshesGregorio Posada Vanegas, Rodolfo Silva Casarín, Sébastien de BryeThis study presents a three dimensional model for the transport of conservative contaminants, which can be used for bodies of water which are affected by winds and/or tides. The model solves the equation of mass transport, based on results obtained using a hydrodynamic model for shallow waters that works in a finite volume scheme and a type of hierarchical grid, … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,578 accessesView PDFCite
Research ArticleOpen accessIn the keywordsParticle Size Determination in Rice Bran Testing with Various Levels of Rice Husks Using Ultrasonic WavesUrip Rosani, Iman Hernaman, Rahmat Hidayat, Darmawan HidayatThe principle of ultrasonic waves in detecting materials is based on their physical properties. The size of particles has an impact on various aspects of their composition and function. The limited information that reports the particle size of RH-contaminated RB samples tested using ultrasonic waves is the basis for this study. This study aims to determine the optimal sample particle … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 6 Nov 2024 · 4,357 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProduction of Bioelectricity Using Single Chamber Microbial Fuel CellAhmad Nawaz, Ram Sharan SinghThe present study addressed the application of sandwich-type air cathode microbial fuel cell (ACMFC) for the production of bioelectricity. Activated carbon was pasted on aluminum mesh for the manufacture of anode and cathode. This electrode design eliminated the requirement for carbon cloth or a metal catalyst, resulting in a cathode with excellent activity for oxygen reduction. The findings demonstrated that … …American Journal of Environmental Sciences, Vol. 19, Issue 2 · 4 Sep 2023 · 5,735 accessesView PDFCite
Research ArticleOpen accessIn the keywordsConstraints Optimization for Minimizing Stretch in Bounded-ParameterizationAnuwat Dechvijankit, Hiroshi Nagahashi, Kota AokiIn a mesh parameterization process that generates one-to-one mapping information between a three-dimensional surface and a two-dimensional plane, we need to set some constraint positions in the solving system to define a specific location or size of the mapping plane. In this study, we will discuss how to perform a bounded-parameterization that minimizes distortion based on changing of constraints setting … …Journal of Computer Science, Vol. 12, Issue 9 · 26 Nov 2016 · 7,074 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTHE RATIONAL BEHIND THE SERVAL NETWORK LAYER FOR RESILIENT COMMUNICATIONSPaul Gardner-Stephen, Andrew Bettison, Romana Challans, Jeremy LakemanThe Internet Protocol is the dominant network protocol used in public networks today and has proven to be highly effective for wired networks and wireless networks alike, provided network address allocation can be coordinated. Mesh networks consisting of highly mobile devices present new challenges, especially when the assumption of coordination does not apply. One situation where coordination is not readily … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 7,705 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Optimized Ad Hoc on Demand Distance Vector Routing Protocol for Wireless NetworksV. Ponniyin Selvan, S. Senthil KumarProblem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUnmet Needs in Chronic Obstructive Pulmonary Disease: A Metasynthesis ProtocolRebecca T. Disler, Anna Green, Tim Luckett et al.Problem statement: Chronic obstructive pulmonary disease is a chronic progressive illness. Despite the high burden experienced by individuals in the advanced stages of illness, individuals with advanced COPD continue to have unmet needs and limited access to palliative care. This Metasynthesis seeks to describe: the barriers and facilitators care access and provision; the unmet needs of individuals with advanced COPD, … …International Journal of Research in Nursing, Vol. 3, Issue 1 · 19 Jun 2012 · 7,579 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFlexible Topology Migration in Optical Cross Add and Drop Multiplexer in Metropolitan Ring NetworkMohammad Syuhaimi Ab-RahmanProblem statement: Optical Cross Add and Drop Multiplexer (OXADM) is a recently invented optical networks device. Approach: A design with a purpose to combine the operational concepts of Optical Add-Drop Multiplexer (OADM) and Optical Cross Connect (OXC) has been developed. It is developed by studying the drawbacks in existing devices and with some excellence features added. OXADM is introduced to … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,635 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSimulation of Airflow and Aerodynamic Forces Acting on a Rotating Turbine VentilatorA.S. Farahani, N.M. Adam, M.K.A. AriffinProblem statement: Rotating turbine ventilators were generally found in most countries. They were simple in structure, light in weight and cheap to install. It was quite surprising that, the aerodynamics of this common device had not been numerically examined and the design process of most of these ventilators had developed progressively through trial and error methods. Approach: This study was … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,711 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Method for Constructing the Coefficients of Pressure Correction Equation for Colocated Unstructured GridsR. Rafee, H. RahimzadehOne of the important equations in numerical solution of Navier Stokes equations is the pressure correction equation. In this article, a new method for constructing the coefficients of this equation for colocated unstructured meshes is proposed. This method is based on momentum interpolation. The method is compared with the approach adopted in literature. The complete discretization of the Navier Stokes … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,137 accessesView PDFCite
