Research ArticleOpen accessIn the abstractMedical Image Compression with Lossless Region of Interest Using Adaptive Active ContourR. Loganathan, Y. S. KumaraswamyProblem statement: With increasing bandwidth, digital medical image storage and transmission is a boon to patients and health professionals alike. Medical images are available instantly and avoid the need to carry the data physically. Popular imaging techniques extensively used in medicine include X-Ray, Magnetic Resonance Imaging (MRI), Ultrasound and Computed Tomography (CT). The images produced from the above techniques can … …Journal of Computer Science, Vol. 8, Issue 5 · 1 Mar 2012 · 7,723 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKinematic Analysis of Exoskeleton Suit for Human ArmSurachai PanichProblem statement: There are many robotic arms developed for providing care to physically disabled people. It is difficult to find robot designs in literature that articulate such a procedure. Therefore, it is our hope that the design work shown in this study may serve as a good example of a systematic method for rehabilitation robot design. Approach: The arm exoskeleton … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,803 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Characteristics of Leachate and Groundwater Pollution at Municipal Solid Waste Landfill of Ibb City, YemenEsmail Al Sabahi, S. Abdul Rahim, W.Y. Wan Zuhairi et al.Problem statement: Yemen one of the developing country suffering from water pollution. Landfill is one of the source of water pollution. There are several boreholes located close to Ibb landfill used for drinking water. A study of composition of landfill leachate and groundwater pollution was conducted at Ibb landfill, which is located at Al-Sahool area, north of Ibb City, Yemen. … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 9,186 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Biomechanical Composite Model to Determine Effective Elastic Moduli of the CNS Gray MatterMehdi Khoshgoftar, Siamak Najarian, Farhad Farmanzad et al.Brain tissue is a heterogeneous material with complicated microstructural features. Models based on microstructure can lead to more accurate and physically realistic predictions of mechanical characteristics of brain tissue. A two-step Mori-Tanaka/Voigt homogenization procedure is implemented into a 3D microstructurally-based multi-phase composite model, composed of randomly-oriented elastic axons, dendrites and neuronal cell bodies surrounded by an elastic matrix. The effects … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,775 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOpen ended-coaxial Cable Measurements of Saturated Sandy SoilsAlberto GodioThe application of electromagnetic methods in the radar and micro-wave frequency band allows the fluid content of soils to be estimated; the heuristic or physically-based models permit to relate the observed electrical permittivity of the soils with the porosity and fluid saturation. The role of the effect of the free water and bound water in the overall electromagnetic behaviour of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,800 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement ProductionMohd Sobri Idris, Khairul Nizar Ismail, Shamsul Baharin Jamaludin et al.Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of α±-belite at higher temperature (around 1300°C), then … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,498 accessesView PDF Cite
