Research ArticleOpen accessIn the author namesCUCKOO SEARCH-AIDED LMS ALGORITHM FOR CHANNEL ESTIMATION IN MC-CDMA SYSTEMSS. Balaji, N. VasudevanIn the progress of transmission systems that uses the diversity in various domains, the execution of competent baseband receivers categorized by affordable computational load is an essential thing. This would be an imperative point in the future expansion of 4G systems in which the space, time and frequency diversity will be merged together to enhance the system throughput. Here, we … …Journal of Computer Science, Vol. 10, Issue 6 · 27 Jan 2014 · 7,100 accessesView PDFCite
Research ArticleOpen accessIn the author namesA NOVEL SPEECH ENHANCEMENT APPROACH BASED ON MODIFIED DCT AND IMPROVED PITCH SYNCHRONOUS ANALYSISV. R. Balaji, S. SubramanianSpeech enhancement has become an essential issue within the field of speech and signal processing, because of the necessity to enhance the performance of voice communication systems in noisy environment. There has been a number of research works being carried out in speech processing but still there is always room for improvement. The main aim is to enhance the apparent … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 21 Nov 2013 · 6,802 accessesView PDFCite
Research ArticleOpen accessIn the author namesADAPTIVE EXPERT SYSTEM FOR CALCULATION OF REAL EAR INSERTION GAIN FOR DIGITAL HEARING AIDSadagopan Rajkumar, S Muttan, Balaji PillaiThe various gain calculating formulae for digital hearing aids is analyzed for different subjects to find out suitable adaptive gain formula for most successful gain recommendations. The object of the work is to design and develop an adaptive expert system, which could be effectively used to perform screening tests to identify the level of hearing impairment and recommend suitable gain … …OnLine Journal of Biological Sciences, Vol. 13, Issue 3 · 4 Sep 2013 · 6,982 accessesView PDFCite
Research ArticleOpen accessIn the author namesTraversal Algorithm for Complete CoverageKavitha Thiayagarajan, Coimbatore Ganeshsankar BalajiThere are many applications which require complete coverage and obstacle avoidance. The classical A* algorithm provides the user a shortest path by avoiding the obstacle. As well, the Dijkstra’s algorithm finds the shortest path between the source and destination. But in many applications we require complete coverage of the proposed area with obstacle avoidance. There are LSP, LSSP, BSA, spiral-STC … …Journal of Computer Science, Vol. 8, Issue 12 · 15 Dec 2012 · 7,125 accessesView PDFCite
Research ArticleOpen accessIn the author namesVarying Overhead Ad Hoc on Demand Vector Routing in Highly Mobile Ad Hoc NetworkV. Balaji, V. DuraisamyProblem statement: An inherent feature of mobile ad hoc networks is the frequent change of network topology leading to stability and reliability problems of the network. Highly dynamic and dense network have to maintain acceptable level of service to data packets and limit the network control overheads. This capability is closely related as how quickly the network protocol control overhead … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the author namesParticle Swarm Optimization Approach for Optimal Design of Switched Reluctance MachineMahadevan Balaji, Vijayarajan KamarajProblem statement: Switched Reluctance Motors (SRMs) are widely used in various applications due to their inherent simplicity and rugged construction In SRM, torque output and torque ripple are sensitive to stator and rotor pole arcs and their selection is a vital part of SRM design process. In this study Particle Swarm Optimization technique is proposed for determining optimum pole arc … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,332 accessesView PDFCite
Research ArticleOpen accessIn the author namesEmission and Combustion Characteristics of Si Engine Working Under Gasoline Blended with Ethanol Oxygenated Organic CompoundsDhanapal Balaji, Periyasamy Govindarajan, Jayaraj VenkatesanProblem statement: The objective of this study is to investigate the effect of using unleaded gasoline and additives blends on Spark Ignition engine (SI engine) combustion and exhaust emission.

Research ArticleOpen accessIn the author namesCytoprotective Effect of UlGen, a Polyherbal Formulation against Physical and Chemical Factor Induced Gastric Ulcers in Wister Albino RatsT. S. Muralidhar, Anna Balaji, Chinmay Bandopadhyay, S. L. ShanthaProblem statement: UlGen, a Polyherbal formulation, was investigated for its possible Ulcero-protective activity in ulcerogen and Cold-restraint stress induced Wister rats (Rattus rattus). Oral administration of UlGen, at a dose of 800 mg kg-1 significantly protected the onset of cold-resistance stress induced ulcerations. Approach: It significantly inhibited gastric ulceration induced by alcohol and aspirin. Control group: Alcohol 80% induced ulcer … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 8,182 accessesView PDFCite
