Research ArticleOpen accessIn the abstractEnhancing the Color Set Partitioning in Hierarchical Tree (SPIHT) Algorithm Using Correlation TheoryM. Santhi, R. S.D. Wahida BanuProblem statement: Efficient color image compression algorithm is essential for mass storage and the transmission of the image. The compression efficiency of the Set Partitioning in Hierarchical Tree (SPIHT) coding algorithm for color images is improved by using correlation theory. Approach: In this study the correlation between the color channels are used to propose the new algorithm. The correlation between … …Journal of Computer Science, Vol. 7, Issue 8 · 16 Jul 2011 · 6,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Studies about Phonological Deficit Theory in Children with Developmental Dyslexia: ReviewDr. Emrah CaylakProblem statement: Developmental Dyslexia (DD) or Reading Disability (RD) that was part of a larger heterogeneous group of learning disorders and characterized by unexpected problems in academic performance, despite average intelligence. Approach: Current opinions on the biological basis of dyslexia pointed to problems with phonological processing deficits with resulting poor phonemic awareness. Though there was much support for this hypothesis … …Neuroscience International, Vol. 1, Issue 1 · 30 Jun 2010 · 14,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecurity Challenges in Multicast Communication for Mobile Ad Hoc NetworkS. Gunasekaran, K. DuraiswamyProblem statement: Multicasting communication network accepted a single message from an application and delivered copies of the message to multiple recipients at different locations. Recently, there has been an explosion of research literature on multicast communication environment. The objective of this study were to contribute the complexity of supporting current multicast applications, (i) the lack of reliable multicast transport mechanisms … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing Reading Processing Strategies of Second Language ReadersParilah M. Shah, Aminuddin Yusof, Suhana M. Lip et al.Problem statement: The message that a writer tries to convey in a text would be subjected to several interpretations by readers. Apparently, reading is a complex process of getting input. A well-known researcher offers two views of reading: (i) reading is a process of decoding written symbols and (ii) reading is a process of reconstructing meaning. It has also been … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Low Complexity Lossless Coding Algorithm for Medical ImagesS. E. Ghrare, M.A. Mohd. Ali, K. Jumari, M. IsmailProblem statement: Nowadays a large number of various medical images are generated from hospitals and medical centers with sophisticated image acquisition devices, the movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve and transmit the volume of digital images. Thus digital image data compression is necessary in order to solve this problem. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractReed-Muller Codec Simulation PerformanceO. O. Khalifa, A. H. Abdullah, N. Suriyana et al.The approach to error correction coding taken by modern digital communication systems started in the late 1940's with the ground breaking work of Shannon, Hamming and Golay. Reed-Muller (RM) codes were an important step beyond the Hamming and Golay codes because they allowed more flexibility in the size of the code word and the number of correctable errors per code … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 7,284 accessesView PDFCite
Research ArticleOpen accessIn the abstractTesting Virtual Reconfigurable Circuit Designed For A Fault Tolerant SystemP. Nirmal Kumar, S. Anandhi, M. Elancheralathan, J. Raja Paul PerinbamThis research describes about the testing of virtual reconfigurable circuit (VRC) designed and implemented for a fault tolerant system which averages the (three) sensor inputs. The circuits that are to be tested are those which are successfully evolved in this system under different situations such as (i) all the three sensors are faultless (ii) one of the input sensor fails … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractCaller Line Identity Delivery: A Computerized Call Alert ApplicationZoubir HamiciThe subject of this study was to analyze the Frequency Shift Keying caller ID FSK transmission protocol used by Jordan Telecom. and implement a call alert computer application. An FSK decoder is presented and a decoding algorithm based on asynchronous data communication is discussed. Data is captured through the RS232 serial port and a 32-bit software is presented as a … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,906 accessesView PDFCite
