Research ArticleOpen accessIn the abstractFLANN Detector Based Filtering of Images Corrupted by Impulse NoiseBanshidhar Majhi, Mowafak FathiWe present a novel non-linear scheme for image restoration based on neuro-detector using Functional Link Artificial Neural Network (FLANN) followed by an improved spatial filter. The method is applied to images corrupted by impulse noise with varying strengths and different noise probability. The neural detector is based on the concept of training or learning by examples. When trained properly, the … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractFurther Improvements in Temperature Calculation During Cooling of Fish PackagesF. A. Ansari, K. A. Abbas, J. Bakar et al.In an earlier study, it was demonstrated that the empirical approach used to calculate the surface film conductance resulted into a higher value compared to those obtained from the other methods available in the literature. During further investigations, surface film conductance values were found to gradually decrease with a fall in temperature. When this non-linear variation was used to develop … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractNON-INVASIVE OPTICAL METHOD FOR EPIDERMAL THICKNESS ESTIMATIONAdrian Pena, Miguel Arronte, Eduardo De Posada et al.A non-invasive method to determine epidermal thickness from the intensity of transmitted visible light is proposed. A simple model for passing light through the epidermis layers, then measuring what is transmitted back out of the surface, is implemented by using the Montecarlo method. Simulations revealed that the transmittance is linearly dependent on the thickness of the epidermis and so demonstrated … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 7,478 accessesView PDFCite
Research ArticleOpen accessIn the abstractVehicle-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 PDFCite
Research ArticleOpen accessIn the abstractEfficient Pose Tracking based on Line Segment MatchingJunqiu Wang, Jingjing Cui, Yanjie Gao et al.Pose tracking is a crucial issue for many applications such as robotic tasks and facility operations. Vision-based approaches with non-contact properties are appropriate choices for these tasks. However, vision-based approaches are not sufficiently robust and fast. In this work, we propose a vision-based pose tracking to deal with these problems. We estimate poses using Lie group and Lie algebra representation … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 27 Dec 2018 · 7,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel LC-MS/MS Method for CJ-023423 (Grapiprant) Determination in Rabbit PlasmaElena Baralla, Virginia De Vito, Maria Vittoria Varoni et al.Grapiprant is a new anti-inflammatory drug that preferentially targets the EP4 receptor of prostaglandin E2 limiting the wide range of adverse effects caused by the classical non steroideal anti-inflammatory drugs. The aim of this study was to develop and validate a new, simple, sensitive and rapid Liquid Chromatography tandem Mass Spectrometry method (LC-MS/MS) in order to quantify this novel drug … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 24 May 2018 · 7,988 accessesView PDFCite
Research ArticleOpen accessIn the abstractSystem Dynamics Analysis of the Determinants of the Malaysian Palm Oil PriceSahra Mohammadi, Fatimah Mohamed Arshad, Bilash Kanti Bala, Abdulla IbragimovThis paper investigates the major determinants of the Malaysian palm oil price using a system dynamics approach. System dynamics methodology is very relevant for examining the feedback relationships, non-linearity and delays exist in palm oil market. It helps understand the palm oil market structure and the resultant behavior and performance particularly On crude Palm Oil (CPO) price. The simulation results … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 10 Jul 2015 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractEr3+-Doped Soda-Lime Silicate Glass: Artificial Pink GemstonePichet Limsuwan, Kheamrutai Thamaphat, Jakrapong Kaewkhao, Weeranut KaewwisetEr3+-doped soda-lime silicate glasses of the composition (in mol%) (65-x)SiO2:25Na2O:10CaO:xEr2O3 (where x = 0, 1, 2, 3, 4 and 5) were fabricated by conventional melt quenching technique. The physical and optical properties were measured and investigated. The erbium oxide enters the glass network as a modifier by occupying the interstitial space in the network and generating the NBOs to the … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 29 Aug 2012 · 7,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractExistence of a Total Order in Every SetAbdelmadjid BoudaoudProblem statement: The axiom of choice, guarantees that all set could be well-ordered, in particular linearly ordered. But the proof in this case was not effective, that was to say, non constructive. It was natural to ask if there was mathematics in which we could given a more constructive proof. Approach: We work in the Nelson’s IST which was an … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 16 Mar 2012 · 7,310 accessesView PDFCite
