Research ArticleOpen accessIn the author namesA Novel Botnet Detection System for P2P NetworksAtef Ahmed Obeidat, Majd Mahmoud Al-Kofahi, Mohammad Jazi Bawaneh, Essam Said HanandehBotnets remain an active security problem on the Internet and various computer networks. They are continuously developing with regard to protocols, structure and quality of attacks. Many botnet detection programs are currently available, but only few can detect bots in real-time. The sooner bots are detected the lesser damage they can cause. In this paper, a novel botnet detection system, … …Journal of Computer Science, Vol. 13, Issue 8 · 7 Aug 2017 · 7,407 accessesView PDF Cite

Research ArticleOpen accessIn the author namesModification of Carbon Steel by Laser Surface Melting: Part II: Effect of Laser Beam Power on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe surface hardness has an important effect on the wear resistance of different materials. The present study aims to improve the surface hardness of carbon steel through the application of laser surface melting with suitable conditions. The laser beam power and travelling speed are the main factors that affect the properties of the treated zone. In this study, three different … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 30 Jan 2014 · 7,208 accessesView PDF Cite

Research ArticleOpen accessIn the author namesCharacterization of Aluminum Alloy-Based Nanocomposites Produced by the Addition of AL-TI5-B1 to the Matrix MeltHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study is an attempt to produce aluminum matrix nanocomposites using a certain aluminum alloy (which its melt has high fluidity) as a matrix material and reinforced with hard and stable fine (nano-sized) precipitates. Therefore, Al-Ti5-B1 master alloy and Al-Si alloy of high silicon content were proposed for preparation of such nanocomposites. Three nanocomposites were prepared by adding Al-Ti5-B1 … …Current Research in Nanotechnology, Vol. 4, Issue 1 · 9 Jan 2014 · 7,123 accessesView PDF Cite

Research ArticleOpen accessIn the author namesModification of Carbon Steel by Laser Surface Melting: Part I: Effect of Laser Beam Travelling Speed on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study aims to improve the surface hardness of carbon steel by application of laser surface melting of effective conditions. The travelling speed of laser beam during this treatment is one of the important treatment conditions. This study aims to investigate the effect of laser surface melting with different beam speeds on macro and microstructure as well as the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 2 Jan 2014 · 7,400 accessesView PDF Cite
