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 · 7,854 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEmpirical Validation of Daylight Simulation Tool with Physical Model MeasurementYaik-Wah Lim, Mohd. Hamdan Ahmad, Dilshan Remaz OssenProblem statement: In recent years, daylighting simulation tools have been increasingly used by many architects, engineers and researchers to evaluate the day lighting performances of building design. Most of these tools employ CIE sky models for simulation. However, the accuracy and applicability of these tools for tropical sky are doubtable. The aim of this study was to validate the computer … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,899 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordUsability Requirements of Formal Verification Tools: A SurveyRozilawati Razali, Paul GarrattProblem statement: Formal notations employ mathematical symbols and interpretation to illustrate system elements. The formality imposed by the notations allows the accuracy and consistency of a system model to be confirmed by verification tools. Formal notations on the other hand are difficult to understand and use by most users. As supporting instruments, verification tools are expected to be as usable … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,185 accessesView PDFCite
