Research ArticleOpen accessIn the author namesDevelopment of Empirical Prediction Formula for Penetration of Ogive Nose Hard Missile into Concrete TargetsAhmad Mujahid Ahmad Zaidi, Qadir Bux Alias Imran Latif, Ismail Abdul Rahman, Muhammad Yusof IsmailProblem statement: Concrete is basic construction material used for most of structures. However, the typical vital structures have to be designed as self-protective such as nuclear plants, power plants, weapon industries, weapons storage places and water retaining structures, against any threats like natural disaster tragedy incident or intentionally produced by horrible incidents such as dynamic loading, incident occurs in nuclear … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,448 accessesView PDFCite
Research ArticleOpen accessIn the author namesImproved 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 author namesIsolation and Characterization of Thermophilic Cellulase-Producing Bacteria from Empty Fruit Bunches-Palm Oil Mill Effluent CompostAzhari Samsu Baharuddin, Mohamad Nafis Abd Razak, Lim Siong Hock et al.Problems statement: Lack of information on locally isolated cellulase-producing bacterium in thermophilic compost using a mixture of Empty Fruit Bunch (EFB) and Palm Oil Mill Effluent (POME) as composting materials. Approach: The isolation of microbes from compost heap was conducted at day 7 of composting process where the mixture of composting materials consisted of 45.8% cellulose, 17.1% hemicellulose and 28.3% … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 12,155 accessesView PDFCite
Research ArticleOpen accessIn the author namesProximate Analysis of Dragon Fruit (Hylecereus polyhizus)Ruzainah Ali Jaafar, Ahmad Ridhwan Bin Abdul Rahman, Nor Zaini Che Mahmod, R. VasudevanProblem statement: Dragon fruit (Hylecereus polyhizus) is well known for the rich nutrient contents and it is commercially available worldwide for improving many health problems. Several studies show the proximity value of red pitaya fruits but the nutrient composition of the stem has not been extensively studied. Approach: This study was carried out to measure the proximate analysis of moisture … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 14,057 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Review on Physicochemical and Thermorheological Properties of Sago StarchA. Mohamed, B. Jamilah, K.A. Abbas et al.This study was a part of a research project aiming to investigate the texture characteristics of protein - starch interaction in fish based product keropok lekor. Accordingly, the current review study focused on some physicochemical (molecular weight, viscosity, chemical composition and swelling power) and thermorheological (gelatinization, retrogradation and viscoelsticity) characteristics of sago starch alone and in mixtures with other ingredients … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 9,639 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Review on Some Organic Acids Additives as Shelf Life Extenders of Fresh Beef CutsMohamed B. Jamilah, K.A. Abbas, R. Abdul RahmanThis study was aiming to present some approaches by which the shelf life of fresh beef cuts was extended. These approaches were based on using organic acids. Therefore the work was started with highlighting the deterioration of some quality attributes due to spoilage and pathogenic microorganisms. These attributes included colour, flavour and lipid oxidation changes. In a given holding temperature, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,736 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Different Concentrations and Applications of Calcium on Storage Life and Physicochemical Characteristics of Papaya (Carica Papaya L.)T.M.M. Mahmud, A. Al Eryani-Raqeeb, S.R. Syed Omar et al.Papaya (Carica Papaya L.) fruits index 2 were treated with 1.5, 2.5 and 3.5% solutions of calcium chloride by dipping and vacuum infiltration (-33 Kpa) or untreated (0%) as control. Effects of these treatments were evaluated on storage life and postharvest quality characteristics of papaya. After 21 days of storage at 13±1°C, the fruits were removed from storage for physicochemical … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 9,652 accessesView PDFCite
Research ArticleOpen accessIn the author namesObject Detection using Geometric Invariant MomentMohamed Rizon, Haniza Yazid, Puteh Saad et al.Geometric moment invariant produces a set of feature vectors that are invariant under shifting, scaling and rotation. The technique is widely used to extract the global features for pattern recognition due to its discrimination power and robustness. In this paper, moment invariant is used to identify the object from the captured image using the first invariant (Ø1). The recognition rate … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Oct 2006 · 6,663 accessesView PDFCite
Research ArticleOpen accessIn the author namesFace Recognition using Eigenfaces and Neural NetworksMohamed Rizon, Muhammad Firdaus Hashim, Puteh Saad et al.In this study, we develop a computational model to identify the face of an unknown person’s by applying eigenfaces. The eigenfaces has been applied to extract the basic face of the human face images. The eigenfaces is then projecting onto human faces to identify unique features vectors. This significant features vector can be used to identify an unknown face by … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,940 accessesView PDFCite
Research ArticleOpen accessIn the author namesRisk Assessment Study for Storage ExplosiveS. Saiful Azhar, M. Abdul Rahman, M. Saari et al.In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries.
