Research ArticleOpen accessIn the abstractAssessment of Genotoxic Activity of Para-nitrophenol in Higher Plant Using Arbitrarily Primed- polymerase Chain Reaction (AP-PCR)Mohamed R. EnanParanitrophenol is a common toxic environmental pollutant; the aim of this study was to evaluate the potential of the DNA fingerprinting by AP-PCR assay to detect the DNA damage in the common bean (Phaseolus vulgaris) exposed to different concentrations of paranitrophenol (4.0-720 nM). The changes occurring in the fingerprint patterns were likely to be the result of paranitrophenol-induced DNA damage. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,069 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Modular Architecture for Anaphora ResolutionAllaoua RefoufiAnaphora resolution attempts to determine the correct antecedent of an anaphor (the term pointing back). In what follows, we propose an algorithm for the resolution of anaphoric pronouns that relies on lexical and syntactic knowledge incorporated in a modular approach based on constraints and preferences. Our objective was to find the correct antecedent to the following subject pronouns (il, ils, … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,079 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Ant Algorithm for Swarm-Based Image ClusteringSalima Ouadfel, Mohamed BatoucheA collective approach to resolve the segmentation problem was proposed. AntClust is a new ant-based algorithm that uses the self-organizing and autonomous brood sorting behavior observed in real ants. Ants and pixels are scatted on a discrete array of cells represented the ants’ environment. Using simple local rules and without any central control, ants form homogeneous clusters by moving pixels … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractRoundup of Graphical Navigation Helpers on the WebChabane Khentout, Mahieddine Djoudi, Lamri DouidiDespite the recent research, the Web remains mainly constituted of an ever-growing network of documents. As it becomes easier to publish documents, as the number of users and thus publishers, increases and as the number of documents grows, searching for information is turning into a cumbersome and time-consuming operation. Because of the loose interconnection between documents, people have difficulty remembering … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractWound Healing Process of Uncomplicated “Rusterholz” Ulcer, Following Treatment by Wooden Block and Hoofgel® in Bovine Hoof: Histopathological AspectsH. Azarabad, I. Nowrouzian, E. Soleymani et al.A broad and very detailed histopathological knowledge on cutaneous wound healing particularly in human skin is available, but few studies have documented this event in bovine claw sole ulcers. It seems the mechanism of wound healing might be basically the same followed by second intention healing which is finished in a period of time by formation of granulation tissue in … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 7,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Simulator: An Educational Tool for Computer ArchitectureMihyar HessonThe great advancement in computer architecture and cache memory design and technology had a considerable influence on the way computer architecture was taught in universities. This requires students to be able to visualize the detailed activities that take place within a computer processor and its interaction with memory system. Computer simulators could effectively be used to enhance the understanding and … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Method to Track Line Segment in Sequence of Images Using Only its SlopeS. Ait Kaci Azzou, S. LarabiIn this paper, we present a novel approach to track a line segment in the sequence of images obtained by camera in motion. We use the slope of segment as feature to track. The proposed method is based only on the formalism of the slope of the segment. We use the definition of the projection of points and the relation … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cooperative Intelligent Decision Support System for Contingency ManagementAbdelkader ADLATraditional Decision Support Systems (DSS) give not enough possibilities of intervention to the user. These systems are reduced to an insular and very technical state in which the objective is not support decision but to dump data on the screen in the hope that the user will know what to do with. In complex situations, decision is not structured and … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractA framework to Deal with Missing Data in Data SetsLuai A. Shalabi, Mohannad Najjar, Ahmad A. KayedMost information systems usually have some missing values due to unavailable data. Missing values minimizing the quality of classification rules generated by a data mining system. Missing vales also affecting the quantity of classification rules achieved by the data mining system. Missing values could influence the coverage percentage and number of reducts generated. Missing values lead to the difficulty of … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 7,140 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Approach to Digital Objects Storage and RetrievalKhalil Shihab, Haider Ramadhan, Nida Al-ChalabiImage retrieval systems are becoming increasingly important in areas of research and commercial use. The storage of digital objects in the traditional databases is considered inadequate because of the extensive precise data required for successful retrieval. In addition, the retrieval process has been implemented using content-based image retrieval (CBIR) that relies on retrieving stored images from a collection by comparing … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,497 accessesView PDFCite
