Review ArticleOpen accessIn the author namesSurvey on Representation Techniques for Malware Detection SystemGamal Abdel Nassir Mohamed, Norafida Bte IthninMalicious programs are malignant software’s designed by hackers or cyber offenders with a harmful intent to disrupt computer operation. In various researches, we found that the balance between designing an accurate architecture that can detect the malware and track several advanced techniques that malware creators apply to get variants of malware are always a difficult line. Hence the study of … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 10 Jul 2017 · 8,590 accessesView PDFCite
Research ArticleOpen accessIn the author namesDirect Analysis of Six Pharmaceuticals using Online Solid Phase Extraction Liquid ChromatographySiti Norbayu Mohd Subari, Rozita Osman, Norashikin SaimIn this study, three parameters (sample volume, cleanup and elution step) in large volume injection online Solid Phase Extraction Liquid Chromatography with diode array detection (SPE-LC) were optimized for the determination of six pharmaceuticals in wastewater samples. Preconcentration and separation were carried out using 2 columns, Dionex Ion Pac AG14A and Acclaim Polar Advantage II. Response Surface Methodology (RSM) was … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 31 Mar 2017 · 7,518 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Improved Speed-Density Relationship Model for Pedestrian FlowLuthful Alahi Kawsar, Noraida Abdul Ghani, Anton Abdulbasah Kamil, Adli MustafaThe speed-density relationship performs as a basis to realize the behavior of a complex system such as vehicular or pedestrian traffic flow. Based on the speed-density relationship, the relationships between other pedestrian characteristics such as speed-flow, flow-density and speed-pedestrian module could be derived. Compared to vehicular flow, very little research has been done to develop a general model to describe … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Jan 2017 · 7,869 accessesView PDFCite
Research ArticleOpen accessIn the author namesCFD-PBE Modelling and Simulation of Enzymatic Hydrolysis of Cellulose in a Stirred TankNorazaliza Mohd Jamil, Qi WangRenewable energy or biofuel from lignocellulosic biomass is an alternative way to replace the depleting fossil fuels. The production cost can be reduced by increasing the concentration of biomass particles. However, lignocellulosic biomass is a suspension of natural fibres and processing at high solid concentration is a challenging task because it will affect the mixing quality between the enzyme and … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 25 Oct 2016 · 8,002 accessesView PDFCite
Research ArticleOpen accessIn the author namesOne-Dimensional Simulation of Diffusion and Advection Effects in Enzymatic Hydrolysis of CelluloseNorazaliza Mohd Jamil, Qi WangEnzymatic hydrolysis process to transform lignocellulosic cellulose into sugar in a bioreactor tank involves different controlling factors such as advection, diffusion and fragmentation of cellulose chains. Although it has been observed experimentally that enzymatic hydrolysis is strongly influenced by the environmental effects in a tank, these effects have not been adequately quantified. In this study, a current kinetic model for … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 13 Jul 2016 · 7,220 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Improved Positivity Preserving Odd Degree-N Said-Ball Boundary Curves on Rectangular Grid Using Partial Differential EquationAhmed Kherd, Azizan Saaban, Noraziah Haji ManThis paper discusses the sufficient conditions for positivity preserving odd degree-n Said-Ball boundary curves defined on a rectangular grid. We derive a sufficient condition on boundary curves of rectangular Said-Ball patches where the lower bound ordinates are adjusted independently. To construct the boundary curves for each rectangular patch, the Said-Ball polynomial solution of fourth order PDE will be considered where … …Journal of Mathematics and Statistics, Vol. 12, Issue 1 · 10 Apr 2016 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the author namesPterostilbene Enhanced Anti-Methicillin Resistant Staphylococcus aureus (MRSA) Activity of OxacillinSiti Fairuz Ishak, Ahmad Rohi Ghazali, Noraziah Mohamad Zin, Dayang Fredalina BasriMethicillin-resistant Staphylococcus aureus (MRSA) is a deadly pathogen that initially was limited to hospital and healthcare facilities but has gradually became a growing problem in healthy children and adults. Pterostilbene belongs to the phenylpropanoid phytoalexin which is involved in plant response to various pathogen and herbivores attack. The aim of this study is to evaluate the anti-MRSA action of pterostilbene … …American Journal of Infectious Diseases, Vol. 12, Issue 1 · 13 Jan 2016 · 8,339 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Converting Tropical Peat Swamp Forest into Oil Palm Plantation on Water QualitySeca Gandaseca, Noraini Rosli, Mohd Hanafi Idris et al.Peat swamp forest is a unique forest and wetlands ecosystem that recognized as one of the most important reservoir of biodiversity and water resources protection. Rapid development particularly for development, agriculture and plantation in peat swamp forest (PSF) area had given negative impacts to its ecosystem included degradation of its water quality. This study was conducted to determine water quality … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 3 Sep 2015 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the author namesGRID-IMAGE PASSWORD BASED SCHEME: ENHANCING MEMORABILITY FEATURES OF PASSWORDSObasan Adebola, Norafida Ithnin, Mohd Zalisham JaliPassword authentication has become a widely recognized element of computer security practices where human users are proven or confirmed as legitimate users for access to secure systems. Using this system, every user needs to recall its password correctly before access can be granted to an intended services or applications. Remembering the secure passwords is an everyday problem for users because … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 9 Sep 2014 · 6,679 accessesView PDFCite
Research ArticleOpen accessIn the author namesCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,590 accessesView PDFCite
