Research ArticleOpen accessIn the abstractA Novel Approach to Signal Detection of Sensor Array Units Using 5-3-1 Rule Based Matched Filter Algorithm with Intelligent IdentifiersMahmoud Z. IskandaraniA novel approach to signal detection and identification was developed and tested. The new algorithm was based on provision of tagging a Matched Filter (MF) with identifiers to recognize the source signal with and without noise, so that classification can be carried out. The algorithm was applied successfully to chemical Sensor Array Units (SAU). Problem statement: Signals obtained from chemical … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Dynamics Studies of Human β-GlucuronidaseIbrahim Ali Noorbatcha, Ayesha Masrur Khan, Hamzah Mohd SallehProblem statement: The enzyme β-glucuronidase is being used as a reporter molecule in the area of genetic engineering, as a component of prodrug therapy in cancer treatment and in the scouring process of cotton fabrics. However, a detailed understanding of the factors responsible for the stability and the activity of this enzyme is still not available. Molecular Dynamics (MD) simulations … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,613 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrity Classification Algorithm of Images obtained from Impact Damaged Composite StructuresMahmoud Z. IskandaraniProblem statement: Many NDT systems used for damage detection in composites are difficult to apply to complex geometric structures, also, they are time-consuming. As a solution to the problems associated with NDT applications, an intelligent analysis system that supports a portable testing environment, which allowed various types of inputs and provided sufficient data regarding level of damage in a tested … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Thermal Comfort: A Study at Closed and Ventilated Call CentreA. R. Ismail, N. Jusoh, N. K. Makhtar et al.Problem statement: The aims of study were to investigate the effects of environmental factors including the human physiology and thermal comfort during the cycle of process works in workplace. Approach: The selected production line was handling the restoration of trouble report. The environment examined was the relative humidity (%), wind speed (m sec-1), illuminance (lux) and air temperature (°C) of … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Dielectric Model for Polyvinyl Alcohol-Water Hydrogel at Microwave FrequenciesYou Kok Yeow, Zulkifly Abbas, Kaida Khalid, Mohamad Zaki Abdul RahmanProblem statement: The study described rigorous dielectric modeling for Polyvinyl Alcohol (PVA)-water hydrogel mixture at microwave frequencies. Approach: A commercial open-ended coaxial sensor was used to measure the dielectric constant, loss factor and ionic conductivity, σ of PVA-water hydrogel mixture ranging concentration of 80-100% water content. Results: The sensor was operating between 0.13 and 20 GHz at and above of … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,045 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Seven-Lump Kinetic Model in the Fluid Catalytic Cracking UnitMehran Heydari, Habib AleEbrahim, Bahram DabirProblem statement: The effective simulation of the Fluid Catalytic Cracking (FCC) operation requires a good understanding of many factors such as, reaction kinetic, fluid dynamics and feed and catalyst effects. Approach: In this model the reactor has been considered as an isothermal riser. The reactions in the riser occur with the fluid and the solids in ideal plug flow. Because … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutritional Value of the Maize Stalk Borer and American Bollworm as Unconventional Protein SourcesA.E. Ghaly, F.N. AlkoaikProblem statement: The maize stalk borer and American bollworm were grown in an artificial media to evaluate their potential as human food sources. Approach: Both cultures were started from moths and the life cycle and culture structures were evaluated. Results: The larvae of both insects reached maximum weight and maximum length at the same time.
