Research ArticleOpen accessIn the keywordsDesign of Low- Power High-Speed Error Tolerant Shift and Add MultiplierK. N. Vijeyakumar, V. Sumathy, Sriram Komanduri, C. Chrisjin Gnana SujiProblem Statement: In this study, we had proposed a low power architecture for high speed multiplication. Approach: The modifications to the conventional shift and add multiplier includes introduction of modified error tolerant technique for addition and enabling of adder cell by current multiplication bit of the multiplier constant. The proposed architecture enables the removal of input multiplexer, switching of adder … …Journal of Computer Science, Vol. 7, Issue 12 · 18 Oct 2011 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpartan-3AN Field Programmable Gate Arrays Truncated Multipliers Delay StudyMohammed H. Al MijalliProblem statement: The image processing applications, such as MPEG video compression used in CT scan frames requires real time conditions and the algorithms should be verified and optimized before implementation which cannot be done with Application Specific Integrated Circuits (ASICs) because they are not reconfigurable and cost is very high. Approach: The FPGA is a viable technology that could be … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,428 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Field Programmable Gate Array Implementation of Basic Building Blocks for Power-Efficient Baugh-Wooley MultipliersMuhammad H. Rais, Bandar M. Al-Harthi, Saad I. Al-Askar, Fahad K. Al-HusseinProblem statement: As growing demands on portable computing and communication systems, the power-efficient multipliers play an important role. In these multipliers basic multiplication follows the Baugh-Wooley algorithms and can easily be implemented using Field Programmable Gate Array (FPGA) devices because the development cost for Application Specific Integrated Circuits (ASICs) are high. These algorithms should be verified and optimized before implementation. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,123 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPitch and Timbre Determination of the AngklungMohd Ridzuwary Mohd Zainal, Salina Abdul Samad, Aini Hussain, Che Husna AzhariThis research describes the pitch and timbre determination of the angklung, a musical instrument made entirely out of bamboo. An angklung has two main parts: the frame and the rattle tubes. The pitch of the rattle tubes can be determined using a formula that takes into consideration the length and diameter of the air resonator. This is compared with the … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 9,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon-Decimated Wavelet Transform and Vector Quantization for Lossy Medical Images CompressionHend A. Elsayed, Qusay E. Majeed, Mohammed M. El SherbinyThis study presents a new approach for lossy medical image compression using vector quantization. Recently, the digital image has been a reliable replacement for a hard copy of medical images, therefore, an effort has been made to ensure maintaining high-quality images to use for archiving, classification, or automated diagnostics support. Although the medical application contains all sorts of the images … …Journal of Computer Science, Vol. 19, Issue 3 · 24 Feb 2023 · 5,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractImage Super-Resolution using Auto-Encoders with Parallel Skip-ConnectionsLisha Pulickal Purushothaman, Jayasree Vadakke KadangoteSuper-resolutionimages are highly desired when employed for numerous analytical purposes andobviously because of their superior attractive visual effect. To create aHigh-Resolution (HR) image from one or more Low-Resolution (LR) images, animage super-resolution technique is used. When dealing with naturalenvironments and settings, it is not always easy to access high-resolutionimages. The main barriers to the same are limitations in acquisition methods.In … …Journal of Computer Science, Vol. 18, Issue 11 · 11 Nov 2022 · 6,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompressive Sensing Theory for Improving the Robustness and the Security of the Discrete Wavelet Transform-Singular Value Decomposition Watermarking SchemeRasha Shoitan, Sawsan Morkos GharghoryDigital watermarking has been suggested as a solution to protect copyright and ownership of digital images. The effective watermarking scheme should satisfy imperceptibility, robustness, capacity and security requirements. In this research, the security issue and the lack of reconstruction quality of the watermark logo of the integration of Discrete Wavelet Transform (DWT), Singular Value Decomposition (SVD) and Compressive Sensing (CS) … …Journal of Computer Science, Vol. 17, Issue 4 · 28 Apr 2021 · 6,599 accessesView PDFCite

Research ArticleOpen accessIn the abstractDesign and Implementation of Myoelectric Controlled ArmTariq M. Younes, Mohammad A. AlKhedher, Abdel-Hamid Soliman, Aiman Al AlawinIn this study a discrimination system, using a neural network for Electromyogram (EMG) externally controlled Arm is proposed. In this system, the Artificial Neural Network (ANN) is used to learn the relation between the power spectrum of EMG signal analysed by Fast Fourier Transform (FFT) and the performance desired by handicapped people. The Neural Network can discriminate 4 performances of … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 16 Sep 2019 · 6,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractFractal Dimension for Lung Sound Classification in Multiscale SchemeAchmad Rizal, Risanuri Hidayat, Hanung Adi NugrohoLung sound is a biological signal with the information of respiratory system health. Health lung sound can be differentiated from other pathological sounds by auscultation. This difference can be objectively analyzed by a number of digital signal processing techniques. One method in analyzing the lung sound is signal complexity analysis using fractal dimension. To improve the accuracy of lung sound … …Journal of Computer Science, Vol. 14, Issue 8 · 24 Aug 2018 · 9,279 accessesView PDFCite
