Research ArticleOpen accessIn the abstractA Transformation-oriented Methodology to Knowledge-based Conceptual Data Warehouse DesignOpim S. Sitompul, Shahrul A. NoahApplications of artificial intelligence (AI) technology in the form of knowledge-based systems within the context of database design have been extensively researched particularly to provide support within the conceptual design phase. However, a similar approach to the task of data warehouse design has yet to be seriously initiated. In this paper, we proposed a design methodology for conceptual data warehouse … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractGross and Histomorphological Studies of Femoral Head Resurfacing in DogD. Sharifi, A. Razaei, D. Savadkouhi et al.The foetal skull bone as a biological graft was investigated. This study was conducted on Fifteen adult mixed - breed normal dogs 12 to 24 months with weighing 21.4=3.6 Kg .Dogs were randomly divided into 3 groups of 5 animals each. The foetal skull bone of 45 days old was collected from one pregnant bitch via cesarean method. The right … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 1 · 31 May 2006 · 6,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Study Using FE Code (PLAXIS) on the Geotechnical Behavior of Shell FootingsBujang B.K. Huat, Thamer A. MohammedThis study describes a study on the geotechnical behavior of shell footing using a non-linear finite element analysis with a finite element code, PLAXIS. The shell footing is found to have a better load carrying capacity compared with the conventional slab/flat footing of similar cross sectional area. The FE analysis also showed a reasonably good agreement with the laboratory experimental … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeisser’s Cycle of Perception: Formal Representation and Practical ImplementationIgor A. Chimir, Waheeb A. Abu-Dawwas, Mark A. HorneyThis article presents results of a theoretical investigation of the application of the object-oriented Unified Modelling Language to a formal description of Neisser’s cycle of perception. The article includes class diagrams, modelling the spatial structure of Neisser’s cycle of perception and demonstrates how these formal descriptions can be applied to the area of modelling the problem-independent dialogue process. The basis … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 5,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of A.C. Impedance Spectroscopic and Cyclic Voltammetric Behavior of Some Heterocarbonyl Compounds in Both Aprotic and Aqueous MediaFarouk A. RashwanThe electrochemical behavior of eosin, isatin and alloxan in aqueous KNO3 and NaClO4 solutions on the Hanging Mercury Drop Electrode [HMDE] and in aprotic DMF and CH3CN on the Pt-disk electrode at 298 K was investigated using the Cyclic Voltammetry (CV) and the Electrochemical Impedance Techniques (EIS). In the CV experiment, the electroreduction of eosin in both aqueous and non-aqueous … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractRevisiting Share Market Efficiency: Evidence from the New Zealand Australia, US and Japan Stock IndicesChristopher Gan, Minsoo Lee, Au Yong Hue Hwa, Jun ZhangThis study aims to re-examine the market efficiencies in New Zealand Stock Exchange (NZSE) and Australia Stock Exchange (ASX) stock indices to investigate whether Groenewold’s[1] findings still hold in the period after the financial liberalization (January 1990-January 2003). In addition, the study also examines whether the larger US NYSE and Japanese NIKKEI stock indices have any influence on the NZSE … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,972 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRetrieval of Similar Shapes Under Affine Transform Using Affine Length ParameterizationA. Lakehal, O. El Beqqali, O. Ait ZemzamiProblem statement: In this study, a new descriptor for shape retrieval under affine transformations had been proposed; the affine length parameterization was used in this approach. Approach: The zero crossing of affine curvature was used to extract a descriptor of shapes in database. For each two successive zero crossing points we extract two parameters: the first parameter was a maximal … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Aug 2010 · 7,260 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Initio Theoretical Study for the Electronic Spectra of β-ThioxoketonesRita S. Elias, Bahjat A. Saeed, Dhiyaa K. MuslemProblem statement: β-thioxoketones exist as equilibrium mixtures of the tautomeric enol and enethiol forms which interconvert very rapidly by intramolecular chelate proton transfer. Accordingly their electronic spectra in the u.v.-visible region exhibit absorption bands arising from transitions within the electronic systems involved in these tautomers. Approach: The structures of several β-thioxoketones were geometrically optimized using B3LYP/cc-pVTZ, B3LYP/6-311++G (2d,p), PM2/6-311++G(2d,p) and … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 24 Nov 2011 · 7,858 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordVibrio cholerae O1 Strains of Different Ribotypes have Similar hlyA RFLP Patterns but Different Vacuolating AbilityJorge E. Vidal, Paula Figueroa-Arredondo, Silvia Giono-Cerezo et al.Extensive cytoplasmic vacuolation on Vero and HeLa cells in vitro by the Vibrio cholerae pore forming toxin HlyA, has been previously reported by our group. Vibrio cholerae O1 and non-O1 pathogenic strains show differences in the potential to induce vacuolation, here we study occurring variations on vacuolating cytotoxic ability, related to changes in the nucleotide sequence of the hlyA-orf.
