Research ArticleOpen accessEvery word in the titleRHEOLOGICAL PROPERTIES OF PADDY SOIL UNDER VARIOUS PRESSURE, WATER CONTENT AND TOOL SHAPESI. A. Mari, C. Ji, F. A. Chandio et al.In this study Burger’s four element model was used to analyze rheological parameter of paddy soil of the Southern China. Two types of tool shape include circular shape (with an area of 12.56 cm2) and rectangular shape (with an area of 12.56 cm2) were use to measure the rheological parameter of paddy soil under different loading pressure (7.65, 10.20 and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 14 Dec 2013 · 7,513 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleIMPROVEMENT OF AUTOMATIC HEMORRHAGES DETECTION METHODS USING SHAPES RECOGNITIONNidhal Khdhair El Abbadi, Enas Hamood Al SaadiDiabetic Retinopathy is a medical condition where the retina is damaged because fluid leaks from blood vessels into the retina. The presence of hemorrhages in the retina is the earliest symptom of diabetic retinopathy. The number and shape of hemorrhages is used to indicate the severity of the disease. Early automated hemorrhage detection can help reduce the incidence of blindness. … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,486 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleOn the Influence of Stator Slot shape on the Energy Conservation Associated with the Submersible Induction MotorsM. Sundaram, P. NavaneethanProblem statement: A good design of Submersible Induction Motor is required to maintain maximum efficiency level. This can be achieved in one way by optimum design of magnetic circuit. The magnetic circuit of an Induction Motor is formed by the combination of Stator core, Rotor core and air gap. In applications like Submersible Motor Pumps, the air gap cannot be … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,710 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleIdentification of Novel Human Immunodeficiency Virus-1 Integrase Inhibitors by Shape-Based Virtual ScreeningT.K. Omprakash, A. Thamarai Selvan, A. Shahul Hameed, S.P. GeethaProblem statement: Human Immunodeficiency Virus-1 (HIV-1) is causative agent of the immune system disease, Acquired Immune Deficiency Syndrome (AIDS). Majority of anti-HIV drugs target reverse transcriptase and protease enzymes. Toxicity and development of multidrug resistant HIV-1 virus strains are the reasons for studying new targets in HIV-1 replication process for identifying novel inhibitor with low toxicity and high activity. Approach: … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Dec 2010 · 7,191 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleFish Recognition Based on Robust Features Extraction from Size and Shape Measurements Using Neural NetworkMutasem Khalil Alsmadi, Khairuddin Bin Omar, Shahrul Azman Noah, Ibrahim AlmarashdehProblem statement: Image recognition is a challenging problem researchers had been research into this area for so long especially in the recent years, due to distortion, noise, segmentation errors, overlap and occlusion of objects in digital images. In our study, there are many fields concern with pattern recognition, for example, fingerprint verification, face recognition, iris discrimination, chromosome shape discrimination, optical … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 9,299 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleVehicle-Fixed-Frame Adaptive Controller and Intrinsic Nonlinear PID Controller for Attitude Stabilization of a Complex-Shaped Underwater VehicleChanaka Thushitha Bandara, Lakmali Nadeesha Kumari, Sanjeeva Maithripala, Asanga RatnaweeraIn this study we present attitude stabilization using a vehicle-fixed-frame adaptive controller and an intrinsic nonlinear PID controller for a low-speed Autonomous Underwater Vehicle (AUV), of complex shape. Controlling an AUV poses a huge challenge because of the non-linearity, time variance and unpredictable external disturbance, as well as because its dynamics and hydrodynamic parameters are difficult to identify due to … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 7 Dec 2020 · 6,987 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleA Comparison between Electrical and Optical Chromatic Dispersion Compensation in Wavelength Divison Multiplexing Network Regarding to Electrical Pulse ShapesMohammad Syuhaimi Ab-Rahman, Majid MoghaddasiProblem statement: Besides of some impairment that has been inherited form single channel, specialists confronted with new obstacles in WDM implementation which bared them for achieving desired performance. Although Chromatic Dispersion (CD) exists in single channel too, it can worsens new nonlinearities which are occurs just in WDM systems. So CD compensation in WDM is even more vital than single … …Journal of Computer Science, Vol. 8, Issue 1 · 29 Oct 2011 · 6,920 accessesView PDF Cite
