Research ArticleOpen accessIn the keywordsEvaluation of Surface Drag Interval in the Variable SituationsParisa Ashrafi, Amir Hossein Ashrafi, Hossein Gholami et al.Tools applied in different fields of engineering are artificial neural networks to model non-linear systems which are efficient and useful. Artificial neural networks consist of input and output layers with one or more hidden layers between them. In fact, one or more processing elements or neurons are used in each layer. Input layer neurons are the independent variables studied and … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 12 Mar 2022 · 6,001 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImproved 3D Imaging Performance of AFMMd Sohel RanaOver the last three decades the Atomic Force Microscopy (AFM) has played an important role in the field of nanotechnology for imaging and manipulating samples. However, the acquisition of a high-quality imaging performance by an AFM is significantly influenced by its key scanning element called its Piezoelectric Tube Actuator (PTA). In this article, to improve its performance, a multi-input multi-output … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Jan 2020 · 7,295 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 2-12 GHz Low Noise Amplifier Design for Ultra Wide Band ApplicationsV. Vaithianathan, J. Raja, R. SrinivasanProblem statement: The Low Noise Amplifier (LNA) is a core block of an Ultra Wide Band (UWB) receiver since it amplifies a very weak signal received at the antenna to acceptable levels while introducing less self-generated noise and distortions. The LNA design poses a unique challenge as it requires simultaneous optimization of various performance parameters like power gain, input matching, … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 9 Jun 2012 · 7,397 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Simulation of a Soft Switched Dc Boost Converter for Switched Reluctance MotorX. Felix Joseph, S. Pushpa KumarProblem statement: This study presents the design and simulation of a soft switched boost converter for a switched reluctance motor with a closed loop controller. A soft switching scheme is proposed in the converter with minimum components, which reduces the switching loss and stress across the switch so that the harmonic generation is reduced in the output. The switch used … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 2 Feb 2012 · 7,176 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpecifying Processes: Application to Electrical Power DistributionSabah Al-Fedaghi, Lina Al-SalehProblem statement: This study deals with the problem of how to specify processes. Many process specification methodologies have been determined to be incomplete; for example, ISO 9000:2005 defines process as transforming media inputs into outputs. Nevertheless, the author of the Quality Systems Handbook, declares that such a definition is incomplete because processes create results and not necessarily by transforming inputs. … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Analysis of Different Optical Switching ArchitecturesSalman Ali Al-QahtaniProblem statement: Optical Packet Switching (OPS) and transmission networks based on Wavelength Division Multiplexing (WDM) have been increasingly deployed in the Internet infrastructure over the last decade in order to meet the huge increasing demand for bandwidth. Several different technologies have been developed for optical packet switching such as space switches, broadcast-and-select, input buffered switches and output buffered switches. These … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,330 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAdaptive Resonance Theory 1 (ART1) Neural Network Based Horizontal and Vertical Classification of 0-9 Digits RecognitionMbaitiga ZacharieThis study describes the Adaptive Resonance Theory 1 (ART1), an efficient algorithm that emulates the self-organizing pattern recognition and hypothesis testing properties of the ART neural network architecture for horizontal and vertical classification of 0-9 digits recognition. In our approach the ART1 model can self-organize in real time producing stable and clear recognition while getting input patterns beyond those originally … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,346 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSoft Sensor Modeling of Product Concentration in Glutamate Fermentation using Gaussian Process RegressionRongjian Zheng, Feng PanThe on-line control of glutamate fermentation process is difficult, owing to the typical uncertainties of biochemical process and the lack of suitable on-line sensors for primary process variables. A prediction model based on Gaussian Process Regression (GPR) is presented to predict glutamate concentration online. First, Partial Least Squares (PLS) is applied to extract the features of the input secondary variables … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 17 Sep 2016 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEfficacy of Numeric Keypad for Computer Illiterates in Rural ICTPallab Dutta, Mahesh Kumar, B. Sridharan, Vipin TyagiThe world has a vast population of illiterate people who cannot read and write. There are globally about 781 million adults today who fall into this category of illiterate population. The number is even higher for computer illiterates, as not all literate masses qualify to be computer literate due to various compelling factors prevailing. There has been a lot of … …Journal of Computer Science, Vol. 11, Issue 8 · 19 Nov 2015 · 7,294 accessesView PDFCite
