Research ArticleOpen accessIn the author namesMalware Detection Based on Hybrid Signature Behaviour Application Programming Interface Call GraphAmmar Ahmed E. Elhadi, Mohd Aizaini Maarof, Ahmed Hamza OsmanProblem statement: A malware is a program that has malicious intent. Nowadays, malware authors apply several sophisticated techniques such as packing and obfuscation to avoid malware detection. That makes zero-day attacks and false positives the most challenging problems in the malware detection field. Approach: In this study, the static and dynamic analysis techniques that are used in malware detection are … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 9 Jan 2012 · 9,144 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Computer Simulation Model for Automated Quantification of Luteinizing Hormone SecretionAyman Al-Nsour, Hamza A. Ali, Buthynna Al-Dulaimi, Wisam H. Al-SewadiProblem statement: An automated software package is developed for quantifying Luteinizing Hormone (LH) release from pituitary gonadotropes in response to short pulses of Gonadotropin-Releasing Hormone (GnRH). Approach: These computer programs were designed to accommodate the release mechanism that consists of three stages, namely; (1) Production of different concentrations of effectors (such as receptor-hormone binds, G protein interactions, inositol 1,4,5-trisphosphate IP3), … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 6,938 accessesView PDFCite
Research ArticleOpen accessIn the author namesSlantlet Transform for Multispectral Image FusionAdnan Hadi M. Al-Helali, Hamza A. Ali, Buthainah Al-Dulaimi et al.Problem statement: Image fusion is a process by which multispectral and panchromatic images, or some of their features, are combined together to form a high spatial/high spectral resolutions image. The successful fusion of images acquired from different modalities or instruments is a great importance issue in remote sensing applications. Approach: A new method of image fusion was introduced. It was … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,724 accessesView PDFCite
Research ArticleOpen accessIn the author namesGeneralization Aspect of Neural Networks on Upgrading Assimilation Structure into Accommodating SchemeWaleed, A. J. Rasheed, Hamza A. AliProblem statement: Generalization feature enhancement of neural networks, especially feed forward structural model has limited progress. The major reason behind such limitation is attributed to the principal definition and the inability to interpret it into convenient structure. Traditional schemes, unfortunately have regarded generalization as an innate outcome of the simple association, referred to by Pavlov and had been modeled by … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,149 accessesView PDFCite
Research ArticleOpen accessIn the author namesBack Propagation Neural Network Arabic Characters Classification Module Utilizing Microsoft WordA. A. HamzaProblem statement: Arabic character recognition has been one of the last major languages to receive attention. This may be attributed to the inherent complexity of both printed and handwritten Arabic characters. The objectives of this study were to: (i) summarize the main characteristics of Arabic language writing style. (ii) suggest a neural network recognition circuit. Approach: A Neural network with … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,831 accessesView PDFCite
Research ArticleOpen accessIn the author namesSesame Oil As A Protective Agent Against Doxorubicin Induced Cardio Toxicity In RatKaneez F. Shad, Suhail Al-Salam, Alaaeldin A. HamzaThe therapeutic value of doxorubicin (DXO) as anticancer antibiotic is limited by its cardiotoxicity. This study aimed to investigate the protective effect of sesame oil against DXO-induced cardiotoxicity and oxidative stress. The administration of DXO (20 mg/kg) to Wister male rats, increased serum aspartate aminotransferase and creatine kinase activities (as cardiotoxicity indices) as well as cardiac malondialdehyde and protein carbonyl … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the author namesCurcuma longa, Glycyrrhiza glabra and Moringa oleifera Ameliorate Diclofenac-induced Hepatoxicity in RatsAlaaeldin A. HamzaAlthough treatment with therapeutic agents may be one of the main causes of liver toxicity, there have been only limited attempts at thorough research efforts to seek solution. Diclofenac (DIC) is a widely used anti-inflammatory drug that causes liver toxicity. This DIC-induced hepatotoxicity was found to be associated with oxidative damage. In this report, extracts of herbal plants that are … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 9,614 accessesView PDFCite
Research ArticleOpen accessIn the author namesSensitization of Photohemolysis by a New Extraction from Flowers and Aerial Parts of Cichorium Pumilum Jacq: Effects of Inulin and Hydrogen PeroxideM-Ali H. Al-Akhras, Amr Amin, Karima Mohammad et al.Addition of inulin and hydrogen peroxide to new photosensitizers extracted from the flowers and aerial parts of the chicory (Cichorium Pumilum Jacq) have been investigated. Some of the isolated photosensitizers remain unidentified compounds. Chicory extracts are found to be dependent on light and temperature. Higher photohemolysis rate was noticed under the influence of light as compared to temperature. The effect … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the author namesIn Vitro Studies on the Effect of Phototoxicity of A New Photosensitizer Extracted from Flowers and Aerial Parts of Cichorium pumilumM-Ali H. Al-Akhras, Amr Amin, Karima Mohammad et al.New photosensitizers have been extracted from the flowers and aerial parts of the Cichorium pumilum Jacq (chicory). Chicory grows naturally in local wild areas and is known to cause quick death of only white sheep during its flowering season in autumn. Some of those isolated photosensitizers are yet to be further characterized. Preliminary investigations show a high degradation of isolated … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,753 accessesView PDFCite
Research ArticleOpen accessIn the author namesGlobal Behavior of a Higher Order Difference EquationAlaa E. Hamza, R. Khalaf-AllahIn this work we study the asymptotic stability of the nonnegative equilibrium points of the difference equation. We discuss the conditions under which there exist prime period two solutions and semicycles. Finally we investigate the oscillation and the existence of unbounded solutions. …Journal of Mathematics and Statistics, Vol. 3, Issue 1 · 31 Mar 2007 · 7,054 accessesView PDFCite
