Research ArticleOpen accessIn the abstractOptimal Test Time for System-on-Chip Designs using Fuzzy Logic and Process AlgebraG. Rohini, S. SalivahananProblem statement: Test scheduling is crucially important for optimal SoC test automation to allocate the limited available test resources. In this study we introduced a fuzzy based engine to allocate test resources. The minimized test application time can be achieved by test pipelining. However the test power consumption incurred during test procedure must be controlled in order not to offend … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of Virtual Bus Transport Using Synchronous Digital Hierarchy/Synchronous Optical NetworkingR. Hassan, J. Irvine, I. GloverThis study presented a new data link layer design for the virtual bus architecture. The virtual bus is a hierarchical access network offered a broadcast capability for data and signaling. The proposed of the study is to support Quality of Service (QoS) in network. During study, the most promising technology capable of delivering full service access at high data rates … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2009 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Directions in Cryptanalysis of Block CiphersDavood RezaeiPour, Mohamad Rushdan Md SaidProblem statement: The algebraic expression of the Advanced Encryption Standard (AES) RIJNDAEL S-box involved only 9 terms. The selected mapping for RIJNDAEL S-box has a simple algebraic expression. This enables algebraic manipulations which can be used to mount interpolation attack. Approach: The interpolation attack was introduced as a cryptanalytic attack against block ciphers. This attack is useful for cryptanalysis using … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fragile Watermarking Scheme for Image Authentication with Tamper Localization Using Integer Wavelet TransformP. MeenakshiDevi, M. Venkatesan, K. DuraiswamyProblem statement: In recent years, as digital media are gaining wider popularity, their security related issues are becoming greater concern. Method for authenticating and assuring the integrity of the image is required. Image authentication is possible by embedding a layer of the authentication signature into the digital image using a digital watermark. In some applications tamper localization is also required. … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractFixed Representative Colors Feature Extraction Algorithm for Moving Picture Experts Group-7 Dominant Color DescriptorAhmed Ibrahim, Ala'a Al-Zou'bi, Raed Sahawneh, Maria MakhadmehProblem statement: MPEG-7 has defined a set of color descriptors for the multimedia contents; one of these descriptors is the Dominant Color Descriptor (DCD). The DCD adopted the Generalized Lloyd Algorithm (GLA) as a feature extraction technique. However, using this algorithm in image retrieval systems may produce perceptually irrelevant images in the ranked results. Approach: In this study, we proposed … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractNorm Divergence Opportunity Structure and Utilization of Self-Employed Immigrants' QualificationsShahamak Rezaei, Marco GoliProblem statement: Denmark experienced one of the most successful periods of its economy in 2004-2008, with a tremendous reduction of 77% in unemployment. Due to the structural challenges with regard to the labor market the utilization of immigrants’ qualifications has come up to the surface of political and societal debate in Denmark. The focus of this study was challenges to … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 7,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtility Independent Privacy Preserving Data Mining on Vertically Partitioned DataE. Poovammal, M. PonnavaikkoProblem statement: Driven by mutual benefits, or by regulations that require certain data to be published, there has been a demand for the exchange and publication of data among various parties. Data publishing has been ubiquitous in many domains such as medical, business and education. Detailed person-specific data, present in the centralized server or in the distributed environment, in its … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Vegetation Dynamics using Long-Term Normalized Difference Vegetation Index Time-SeriesTamara Bellone, Piero Boccardo, Francesca PerezProblem statement: The Normalized Difference Vegetation Index (NDVI) is the most extensively used satellite-derived index of vegetation health and density. Since climate is one of the most important factors affecting vegetation condition, satellite-derived vegetation indexes have been often used to evaluate climatic and environmental changes at regional and global scale. The proposed study attempted to investigate the temporal vegetation dynamics … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,404 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring the Software Product Quality during the Software Development Life-Cycle: An International Organization for Standardization Standards PerspectiveRafa E. Al-QutaishProblem statement: The International Organization for Standardization (ISO) published a set of international standards related to the software engineering, such as ISO 12207 and ISO 9126. However, there is a set of cross-references between these two standards. Approach: The ISO 9126 on software product quality and ISO 12207 on software life cycle processes had been analysed to investigate the relationships … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 7,856 accessesView PDFCite
Research ArticleOpen accessIn the abstractIonospheric Total Electron Content Response to the December 26, 2004 North Sumatra EarthquakeA. Abdullah, A. F.M. Zain, M. H. Jusoh et al.Problem statement: Ionospheric precursors of earthquake have been studied by scientists and seismologists. This study aims at examining the relationship between the ionosphere and earthquake precursors. The effects of the anomalous electric field that penetrates the ionosphere on the electron concentration can be measured experimentally. This study reports on the variability of the Total Electron Content (TEC) during the December … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,908 accessesView PDFCite
