Research ArticleOpen accessIn the abstractComputer Aided Diagnosis System for Stone Detection and Early Detection of Kidney StonesMs. P.R. Tamilselvi, Dr. P. ThangarajProblem statement: Most of the previous study in diagnosis of kidney stone identifies a mere presence or absence of the stones in the kidney. However proposal in our study even present an early detection of kidney stones which helps to change the diet conditions and prevent the formation of stones. Approach: The study presented a scheme for ultrasound kidney image … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 8,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Analysis of MRR, EWR and Surface Roughness in EDM Milling through Response Surface MethodologyA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) has grown over the last few decades from a novelty to a mainstream manufacturing process. Though, EDM process is very demanding but the mechanism of the process is complex and far from completely understood. It is difficult to establish a model that can accurately predict the performance by correlating the process parameters. The optimum … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 9,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrequency of P/S(XX)P Duplication and FRFE, Absence of LYP in P6Gag of Indian Human Immunodeficiency Virus-1 Subtype C IsolatesKrutika Wadekar, Sudhanshu Pandey, Preeti Jain et al.Problem statement: The presence of a p6 domain at the C-terminus of the Gag polyprotein is a characteristic feature of HIV-1 and other primate lentiviruses. The p6Gag protein is considered as a major phosphoprotein in mature HIV-1 virions and is involved in the viral assembly and budding process. Sequence variation in the p6gag region in HIV-1 has been associated with … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 7,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransient in-Cylinder Gas Flow Characteristics of Single Cylinder Port Injection Hydrogen Fueled EngineM. M. Rahman, Khalaf I. Hamada, M. M. Noor et al.Problem statement: The variation of the in-cylinder gas flow characteristics for single cylinder port injection hydrogen fueled internal combustion engine was investigated through transient state simulation. Approach: One dimensional gas dynamics was described the flow and heat transfer in the components of the engine model. Special attention is paid to selection and correction of heat transfer correlation which describe of … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Capacitance to Voltage Converter for Capacitive Sensor TransducerA.H.M. Zahirul Alam, Nurul Arfah, Sheroz Khan, Md. Rafiqul IslamProblem statement: The design of Capacitance to Voltage Converter (CVC) for capacitive sensor transducer was presented. The proposed design will reduce the size, power consumption and supply voltage of the circuit and can be used in high frequency band transducer. Approach: The design was implemented using the Operational amplifier (Op amp) and capacitive network. The circuit was simulated using the … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Calculation Sensitivity Function for Multi Tasking EnvironmentsHamed Al Rjoub, Ahmed Al-Sha'orProblem statement: Calculating sensitive functions for a large dimension control system to find the unknowns vectors for a linear system in both single and multi processors, is not considered internally compatible with multi tasking environments, so breaking the process can cost time and memory and it couldn't be paused, resumed and saved as patterns for later continuity. This study is … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Aug 2010 · 6,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing an Adaptative Fuzzy-Logic System to Optimize the Performances and the Reduction of Chattering Phenomenon in the Control of Induction MotorM. M. Krishan, L. Barazane, A. KhwaldehProblem statement: Neural networks and fuzzy inference systems are becoming well-recognized tools of designing an identifier/controller capable of perceiving the operating environment and imitating a human operator with high performance. Also, by combining these two features, more versatile and robust models, called “neuro-fuzzy” architectures have been developed. The mo Approach: Motivation behind the use of neuro-fuzzy approaches was based on … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost-Effective Fabrication of Self-Made 1×12 Polymer Optical Fiber-Based Optical Splitters for Automotive ApplicationMohammad Syuhaimi Ab-Rahman, Hadi Guna, Mohd Hazwan Harun et al.Problem statement: Multimode fiber cables can conduct many light rays and can operate free of disruption and with a greater bandwidth than a wireless connection. However, due to a slight variation in the speed of the light rays through the multimode fiber, a signal transmitted by all of these rays becomes spread out. Consequently, the signals become broader and therefore … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrochemical Differentiation of Salinisation Process of the Water in Endoreic Semi-Arid Basin: Case of Rémila Basin, AlgeriaHouha Belgacem, Kherici Nacer, Kachi Slimane, Valles VincentThe aim of this study is to determine and treat a hierarchical basis of the various mechanisms responsible for the space variation of the water quality in a endoreic semi-arid basin. The water chemistry showed a large variability in space and time. The total dissolved solid (TDS) in water increases from upstream to downstream due to the effect of the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractCarbon Nanodots from Frying Oil as Catalyst for Photocatalytic Degradation of Methylene Blue Assisted Solar Light IrradiationMahardika Prasetya Aji, Pradita Ajeng Wiguna, Siti Aisyah Suciningtyas et al.Carbon nanodots (C-Dots) of frying oil could be a photocatalyst for the degradation of methylene blue solution with assisted solar light irradiation.
