Research ArticleOpen accessIn the abstractPerformance of Unequal Error Protection Using Maximum A- posteriori Probability Algorithm and Modified MAP in Additive White Gaussian Noise and Fading ChannelT. Gnanasekaran, K. DuraiswamyProblem statement: In this study we propose a method to improve the performance of Maximum A-Posteriori Probability Algorithm, which is used in turbo decoder. Previously the performance of turbo decoder is improved by means of scaling the channel reliability value. Approach: A modification in MAP algorithm proposed in this study, which achieves further improvement in forward error correction by means … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractTask Scheduling in Real Time Systems with Energy Harvesting and Energy MinimizationArvind Kumar, Bashir AlamEnergy is a major concern in battery operated real time devices (e.g. sensor nodes situated in remote areas) as battery life is solely responsible for the functioning of such devices. For such systems to work continuously and successively a regular source of energy is required. The lifetime of such systems can be increased by reducing the energy consumption and increasing … …Journal of Computer Science, Vol. 14, Issue 8 · 15 Aug 2018 · 8,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Information Content Glossary Relatedness (ICGR) Approach for Short Text Similarity (STS) TasksAli Muftah BenOmran, Mohd Juzaiddin Ab AzizThe measurement of the relatedness of word semantics based on complementary Wikipedia and WordNet-based methods takes two forms, combined and integrative, which are aimed at increasing the semantic space between related words. However, each form has its own set of issues regarding its components and the strategy that is used to combine and integrate corpus-based and knowledge-based methods. In the … …Journal of Computer Science, Vol. 15, Issue 6 · 5 Jun 2018 · 8,004 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA Satellites Help us to Quickly Detect Forest FiresRelly Victoria Virgil Petrescu, Raffaella Aversa, Taher M. Abu-Lebdeh et al.The main idea is that, as the forests of the planet are getting smaller, too much wood is cut and the forests are made too slow, there are also large forest fires due to excessive heat, of people arguing with the law, or simply by chance. Extinguishing fires are generally difficult, interventions being difficult anyway due to the increased fire, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 20 Feb 2018 · 8,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractHYGLASS: Design Proposal for an Integrated Multifunctional Hybrid Glass-Steel StructureMaurizio Froli, Francesco LacconeContemporary cities demand smart communication infrastructures to facilitate the interaction of residents and visitors with the urban environment. Such systems are required to be network-connected, interactive, environmental-sensitive and energetically self-sustaining. Moreover, in outdoor applications they should mark an urban focal point and should be able to satisfy additional public requirements like illumination, transmission of information etc. In the framework of … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 22 Jan 2018 · 7,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractPossible Physical Determination of the Mass, Size, Doubling Time and Density of the Unicellular Organisms Based on the Fundamental Physical ConstantsAtanas Todorov AtanasovIn manuscript the hypothesis 'that the mass, size, doubling time and density of the unicellular organisms (Prokaryotes and Eukaryotes) are determined by the gravitational constant (G, N·m2/kg2), Planck constant (h, J·s) and growth rate vgr (m/s)' is investigated. By scaling analyses it is indicated that the growth rate of the unicellular organisms ranges in a narrow window of 1.0×10-11–1.0×10-10 m/s, … …Physics International, Vol. 7, Issue 2 · 20 Nov 2016 · 8,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractDESIGN OF HIGH-SPEED PARALLEL IN PARALLEL OUT SHIFT REGISTER USING ALGAAS/GAAS MODFET TECHNOLOGYV. Ganesan, K. S. ShajiThis study enumerates the efficient design and analysis of Parallel In Parallel Out (PIPO) shift register using AlGaAs/GaAs MODFET D Flip-flop. The transient and power analysis are obtained with operating voltage at 1.3 V for the D flip-flop and PIPO shift register using pspice tool. There are many issues facing while integrating many number of transistors like delay, power dissipation, … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 8 May 2014 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractFAST IMAGE MATCHING IN HUGE DATABASENidhal K. El Abbadi, Lamis Al SaadiIn today’s multimedia age, images are becoming more and more common in various fields. Database is an area that has found extensive use of images in past few years. With the increased usage of image data, the need to search and matching images efficiently and accurately from a large image database or a cluster of images databases has increased. Image … …Journal of Computer Science, Vol. 10, Issue 8 · 2 Apr 2014 · 6,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractADDITIVE AND MULTIPLICATIVE NOISE REMOVAL BASED ON ADAPTIVE WAVELET TRANSFORMATION USING CYCLE SPINNINGAsem Khmag, Abd Rahman Ramli, Syed Abdul Rahman Al-Haddad, Shaiful Jahari Bin HashimThe need for image restoration is encountered in many practical applications. For instance, distortion due to Additive White Gaussian Noise (AWGN) or in some cases the multiplicative (speckle) one can be caused by poor quality image acquisition. Wavelet denoising attempts to remove these types of noise present in the signal while preserving the signal characteristics, regardless of its frequency content. … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 27 Dec 2013 · 7,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Tchebichef Moment Transform Image Compression using Psychovisual ModelFerda Ernawan, Nur Azman Abu, Nanna SuryanaAn extension of the standard JPEG image compression known as JPEG-3 allows rescaling of the quantization matrix to achieve a certain image output quality. Recently, Tchebichef Moment Transform (TMT) has been introduced in the field of image compression. TMT has been shown to perform better than the standard JPEG image compression. This study presents an adaptive TMT image compression. This … …Journal of Computer Science, Vol. 9, Issue 6 · 1 Jun 2013 · 7,131 accessesView PDFCite
