Review ArticleOpen accessEvery word in the titleRecognizing Dissolved Organic Matter with an Improved Fluorescence Regional Integral MethodZhang Jianguo, Wang Xinyi, Liu Xiaoman et al.The aim of this paper was to study transformations of Dissolved Organic Matter (DOM) in marl rock groundwater. To achieve this, we carried out a series of soil column experiments, using a DOM solution as the water sample and marl rock as the testing rock sample. Three-Dimensional Excitation-Emission Matrix Spectra (3DEEMS) were generated for DOM solutions and the Analytic Hierarchy … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 24 Dec 2019 · 7,288 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Weighted Integral Energy Functional (WIEF) Algorithm: Augmented Reality (AR) for Visualising the Blood Vessels in Breast Implant SurgeriesTaranjit Kaur, Abeer Alsadoon, Paul Manoranjan et al.The use of Augmented Reality (AR) for visualising blood vessels in surgery is still at the experimental stage and has not been implemented due to limitations in terms of accuracy and processing time. The AR also hasn't applied in breast surgeries yet. As there is a need for a plastic surgeon to see the blood vessels before he cuts the … …American Journal of Applied Sciences, Vol. 15, Issue 9 · 7 Nov 2018 · 7,710 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimulation Analysis on Proportional Integral and Derivative Control of Closed Loop DC Motor Drive with Bipolar Voltage SwitchingP. Karpagavalli, A. Ebenezer JeyakumarThis study presents the performance of a new four quadrant single phase DC drive closed loop system controlled by proportional integral and derivative controller with Pulse Width Modulation (PWM) full bridge DC-DC converter using bipolar voltage switching. The proposed method is found to be more efficient in improving the step response characteristics such as reducing the settling time, rise time, … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 29 Jun 2013 · 6,908 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Based Plus Integral Controller for PMBLDC Motor Control using Resonant Pole InverterMuruganantham, PalaniPermanent Magnet Brushless DC (PMBLDC) motor drives are increasingly popular in industrial applications due to rapid progress of technologies in power electronics and the growing demand for energy saving. The increasing demand of energy saving from society is the external force for the development of PMBLDC motor drives. It is however driven by a hard-switching Pulse Width Modulation (PWM) inverter, … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 8,146 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTuning of a Proportional-Integral-Derivative Controller using Multi-Objective Non Dominated Sorting Particle Swarm Optimization Applied to pH Control in Continuous Stirred Tank ReactorC. Agees Kumar, N. Kesavan NairProblem statement: Most of the control engineering problems are characterized by several, contradicting, conflicting objectives, which have to be satisfied simultaneously. Two widely used methods for finding the optimal solution to such problems are aggregating to a single criterion and using Pareto-optimal solutions. Approach: Non-Dominated Sorting Particle Swarm Optimization algorithm (NSPSO) based approach is used in the design of multiobjective … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 6,788 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFault Tolerant Control Using Proportional-Integral-Derivative Controller Tuned by Genetic AlgorithmS. Kanthalakshmi, V. ManikandanProblem statement: The growing demand for reliability, maintainability and survivability in industrial processes has drawn significant research in fault detection and fault tolerant control domain. A fault is usually defined as an unexpected change in a system, such as component malfunction and variations in operating condition, which tends to degrade the overall system performance. The purpose of fault detection is … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,479 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of Abutment Displacement of a Full Height Integral Bridges in Dense Granule BackfillM. H. Alizadeh, A.R. Khalim Rashid, Zamri Chik, S. M. MirhosseinyProblem statement: In this study, the behavior of abutment wall in full height frame integral abutment bridges was investigated. It was seen that the effect of backfill soil resistance on behavior of abutment wall movement is mostly neglected in previous studies. In this research, the final bridge superstructure displacement under temperature-induced forces was formulated. In addition, according to the final … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,352 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation of C*-Integral for Radial Cracks in Annular Discs under Constant Angular Velocity and Internal PressureA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral for single and double-edge cracks in eight annular rotating discs under constant angular velocity with and without internal pressure. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power law creeping finite element analyses have been performed and the results are … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,721 accessesView PDFCite
