Research ArticleOpen accessIn the abstractThe use of Random Forest Classification and K-means Clustering Algorithm for Detecting Time Stamped Signatures in the Active NetworksKamalanaban Ethala, R. Shesadri, N. G. RenganathanIn day to day information security infrastructure, intrusion detection is indispensible. Signature based intrusion detection system mechanisms are often available in detecting many types of attacks. But this mechanism alone is not sufficient in many cases. Another intrusion detection method viz K-means is employed for clustering and classifying the unlabelled data. IDS is a special embedded device or relied software … …Journal of Computer Science, Vol. 9, Issue 7 · 18 Jun 2013 · 7,496 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalytical Study of Signal-to-Noise Ratio for Visible Light Communication by Using Single SourceMohammad Syuhaimi Ab-Rahman, Nurain Izzati Shuhaimi, Luqman Al-Hakim Azizan, Mazen Radhe HassanProblem statement: In this study, optical wireless communication system using visible light is studied for indoor application. Approach: The process started with the calculation on performance of single source white LED where received power, channel DC gain and quality of data transmission (SNR computation) are identified. Through the simulation results, the SNR performance is directly proportional to angle of incident … …Journal of Computer Science, Vol. 8, Issue 1 · 2 Nov 2011 · 7,479 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,983 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling Method of a Low-Pass Filter Based on Microstrip T-Lines with Cut-Off Frequency 10 GHz by the Extraction of its Wave-Scattering Parameters from its Causal Bond Graph ModelHichem Taghouti, Abdelkader MamiProblem statement: This study presented a jointly application of bond graph technique and wave-scattering formalism for a new realization called scattering bond graph model which has the main advantage to show up explicitly the different wave propagation. Approach: For that, we proposed to find the scattering matrix from the causal bond graph model of a low-pass filter based on Microstrip … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,262 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of Protease Inhibitors on Metabolic Complications and Lipodystrophy in Human Immunodeficiency Virus-Infected PatientsMohd Khaza, K. Laxmi Prasad, M. EstariProblem statement: Highly Active Antiretroviral Therapy (HAART)-associated metabolic complications include lipoatrophy (loss of Subcutaneous Adipose Tissue (SAT) and insulin resistance. The risk of Diabetes Mellitus (DM) in Human Immunodeficiency Virus (HIV)-infected patients receiving Highly Active Antiretroviral Therapy (HAART) especially protease inhibitors has not been well defined. Approach: We conducted an analysis in the Hospital of Rajeev Gandhi Institute of Medical … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 6,934 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Geometry and Orientation on Flank Insolation of Streets in an Arid Climate CityMehrdad Mazloomi, Ahmad Sanusi Hassan, Parmis Naraghi Bagherpour, Mohd Rodzi IsmailProblem statement: Whilst at the design stage the various aspects of design impact must be taken into account, the incident solar radiation, insolation, is a key to many environmental aspects of street canyons. In this regard, the configuration of an urban street has a decisive role in magnitude of the solar radiation which it receives on its flank. This study … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,999 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopment 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 PDF Cite

Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModified Center Interpolation Net for Classification of Composite Structures Tested Using Low Frequency Electronic TappingMahmoud Z. IskandaraniProblem statement: Most exhaustive NDT techniques require large capital equipment, are difficult to apply to complex geometric structures and, above all, are time-consuming to use and some take a considerable time to complete.
