Research ArticleOpen accessIn the abstractImproved Vertex Chain Code Based Mapping Algorithm for Curve Length EstimationHabibollah Haron, Amjad Rehman, L.A. Wulandhari, Tanzila SabaProblem statement: Image representation has always been an important and interesting topic in image processing and pattern recognition. However, curve tracing and its relative operations are the main bottleneck. Approach: This research presents the mapping algorithm that covers one of the vertex chain code cells, the rectangular-VCC cell. The mapping algorithm consists of a cell-representation algorithm that represents a thinned … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,841 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopment of Neighbors Atomic Coordinate Tables and Plot-Graphical Representation for Tertiary Structure in ProteinsHamed Fawareh, Jehad Q. Odeh, Nawal Al-OmoushProblem statement: Contact map prediction is an interesting method for its application in fold recognition and protein tertiary structure determination. Approach: This study developed a method to predict a protein tertiary structure from the amino acid sequence using contact map. The method showed prediction a protein in a binary space of exposure states. The approach produced several procedures to finds … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 6,892 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInformation Hiding: A Generic ApproachRiad jabri, Boran Ibrahim, Hadi Al-ZoubiProblem statement: Privacy and security over communication channels are of primary concerns. Due to their complexity and diversity, there is a need for continuous improvements of the adopted solutions. In this study, we consider two of the adopted ones, namely, steganogrphy and cryptography and propose a new information hiding system. Approach: The proposed system was based on a generic approach … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,833 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEfficient Processing for Binary Submatrix MatchingAzzam Sleit, Wesam AlMobaideen, Mohammad Qatawneh, Heba SaadehThe heavy demand for large volumes of digital data has increased the interest in matrix-like representation. Matrices are well organized data structures which are suitable to store uniform data in order to simplify data access and manipulation. For several applications, the need is critical to efficiently search for a specific pattern in matrix structures. A pattern can be represented as … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,616 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopment of Deduced Protein Database Using Variable Bit Binary EncodingB. Parvathavarthini, B. Rajesh Kanna, L. RajeswarideviA large amount of biological data is semi-structured and stored in any one the following file formats such as flat, XML and relational files. These databases must be integrated with the structured data available in relational or object-oriented databases. The sequence matching process is difficult in such file format, because string comparison takes more computation cost and time. To reduce … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,512 accessesView PDF Cite
