Research ArticleOpen accessIn the abstractFocusing of the Flow Capture for Local Exhaust Ventilation SystemsS. Y. Spotar, A. L. SorokinProblem statement: The extraction hoods commonly used as inlet element of the local ventilation systems exhibit limited emission capture over moderate distances from the source of the hazardous emissions. Proposed inclusion of a swirling peripheral jet was found to increase the effective length over which the extraction hood successfully captures harmful fumes. However information on a detailed pattern field of … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinematics Model of Snake Robot Considering Snake ScaleRaisuddin Khan, M. Watanabe, A. A. ShafieProblem statement: In snake robot research, one of the most efficient forms of locomotion is the lateral undulation. However, lateral undulation, also known as serpentine locomotion, is ill-suited for narrow spaces, as the body of the snake must assume a certain amount of curvature to propel forward. Approach: To overcome the inability to adapt to narrow spaces, a novel type … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Performance Analysis of Modified Mid-Square and Mid-Product Techniques to Minimize the Redundancy for Retrieval of Database RecordsK. Meenakshi Sundaram, T. Santhanam, M. Saroja, C. P. SumathiProblem statement: An important tool in the field of education methodology is examination. As far as teaching-learning-evaluation process is concerned, the major task associated with the objective-type examination system is the administration of question paper setting. The lack of expertise and time are the major constraints that are encountered in the task of setting objective type question papers. During retrieval … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 7,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuel and Greenhouse Gas Emission Reduction Potentials by Appropriate Fuel Switching and Technology Improvement in the Canadian Electricity Generation SectorFarshid Zabihian, Alan S. FungProblem statement: In recent years, Greenhouse Gas (GHG) emissions and their potential effects on global climate change have been a worldwide concern. According to International Energy Agency (IEA), power generation contributes more than half of the global GHG emissions. Approach: Purpose of this study is to examine GHG emission reduction potentials in the Canadian electricity generation sector through fuel switching … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Study on Fundamental Frequency Contours of Thai Expressive Speech Using Fujisaki's ModelSuphattharachai ChomphanProblem statement: In spontaneous speech communication, prosody is an important factor that must be taken into account, since the prosody effects on not only the naturalness but also the intelligibility of speech. Focusing on synthesis of Thai expressive speech, a number of systems has been developed for years. However, the expressive speech with various speaking styles has not been accomplished. … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractPractical and Novel Sterilization Approach for the Pathogenic Staphylococcus aureus BacteriaRaftari Mohammad, Azizi Jalilian Farid, A.S. Abdulamir et al.Problem statement: Decontaminating meat surfaces has been the big concern of meat industry. Thus, various intervention strategies have been studied to reduce the level of bacteria on animals’ carcass surfaces. Approach: Mixture of different concentrations 1, 1.5 and 2% of acetic, lactic, propionic and formic acids at 1:1 ratio were spray washed on inoculated meat to evaluate their efficacy in … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 6,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Companies' Age on Safety Culture in the Metal Products IndustryMaryam Ooshaksaraie, Amran Ab. Majid, Muhammad Samudi Yasir, Redzuwan YahayaProblem statement: Safety culture is a complex structure in an organization that includes values and attitudes, most of which are potentially changeable and related to actual accident behavior. In this study, the components of safety culture included organizational commitment, management involvement, employee empowerment, reporting system and rewarding system. Approach: The numbers of occupational injuries in industries have steadily increased during … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombined Thermal Radiation and Mixed Convection in an Inclined Circular DuctW. Lakhal, S. Trabelsi, E. Sediki, M. MoussaProblem statement: Modeling thermal radiation with simultaneous buoyancy and forced convection for real gases flowing inside system with complex geometry is a difficult task encountered in engineering applications. Purpose of this study was to research numerically the interaction of mixed convection and thermal radiation in laminar air flow inside an inclined cylindrical duct with Uniform Wall Heat Flux (UWHF).

Research ArticleOpen accessIn the abstractJob Type Approach for Deciding Job Scheduling in Grid Computing SystemsAsef AL-Khateeb, Rosni Abdullah, Nur’Aini Abdul RashidProblem statement: Meta-scheduling has become very important due to the increased number of submitted jobs for execution. Approach: We considered the job type in the scheduling decision that was not considered previously. Each job can be categorized into two types namely, data-intensive and computational-intensive in a specific ratio. Job ratio reflected the exact level of the job type in two … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Optical Properties of ZnO-TeO2 Glass SystemH. A.A. Sidek, S. Rosmawati, Z. A. Talib et al.Problem statement: Systematic series of ZnO-TeO2 glasses with mole fraction of 0.10-0.40 ZnO content with an interval of 0.05 were studied to obtain their physical and optical properties. Approach: All the glass samples were synthesized by rapid melting quenching method under controlled conditions, while their refractive indices (n) were measured by the EL X-02C high precision ellipsometer. The room temperature … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 14,090 accessesView PDFCite
