2D Compressible Viscous Flow Computations Using Acoustic Flux Vector Splitting (AFVS) Scheme
(Indian Institute of Science, 2007-05-07)The present work deals with the extension of Acoustic Flux Vector Splitting (AFVS) scheme for the Compressible Viscous flow computations. Accurate viscous flow computations require much finer grids with adequate clustering ... -
Adaptive algorithms for admission control of elastic sessions in the internet
In the Internet, the majority of the traffic is elastic, and is characterized by the fact that such traffic can withstand loose bounds on performance guarantees. It is a well-understood fact, however, that once the performance ... -
ANTECEDENTS AND CONSEQUENCES OF HUMAN CAPITAL VALUE ADDITION AMONG KNOWLEDGE PROFESSIONALS
(Indian Institute of Science, 2005-07-13)The last decade has seen the growth of knowledge based industries and knowledge work. It has also witnessed the ever-increasing onslaught of competition and change.Intangibles have become increasingly important factors in ... -
Application Of High Frequency Natural Resonances Extracted From Electromagnetic Scattering Response For Discrimination Of Radar Targets With Minor Variations
(Indian Institute of Science, 2005-10-25)Radars, as the name suggests, were traditionally used for Radio Detection and Ranging. Nevertheless, advances in high resolution electromagnetic simulations, Ultra Wide-Band sources, signal processing and computer technologies ... -
Artificial Neural Network Approach For Characterization Of Acoustic Emission Sources From Complex Noisy Data
(Indian Institute of Science, 2006-12-14)Safety and reliability are prime concerns in aircraft performance due to the involved costs and risk to lives. Despite the best efforts in design methodology, quality evaluation in production and structural integrity ... -
Bimodal Projections Based Features for High Dimensional Pattern Classification
Classification tasks involving high-dimensional vectors are affected by the curse of dimensionality requiring large amount of training data. This is because a high dimensional space with a modest number of samples is ... -
Characterisation and Analysis of a Vibro-fluidised Granular Material
(Indian Institute of Science, 2006-12-12)The present work is concerned with the mathematical modelling of a bed of granular material in a gravitational field vertically fluidised by a vibrating surface. The particles are in rapid motion, and lose energy by inelastic ... -
Compressed Domain Processing of MPEG Audio
(Indian Institute of Science, 2005-02-11)MPEG audio compression techniques significantly reduces the storage and transmission requirements for high quality digital audio. However, compression complicates the processing of audio in many applications. If a compressed ... -
Computational Studies On Certain Problems Of Combustion Instability In Solid Propellants
(Indian Institute of Science, 2006-11-17)This thesis presents the results and analyses of computational studies on certain problems of combustion instability in solid propellants. Specifically, effects of relaxing certain assumptions made in previous models of ... -
Computational Studies On Some Plausible Structures Of The Hydrides And Oxyhydrides Of [36-D6h] Fullerene
(Indian Institute of Science, 2006-11-23)Fullerenes, the highly symmetric molecular carbon clusters, have been in the limelight of scientific research since their discovery by Kroto and coworkers [1]. The focus of experimental and theoretical studies has centered ... -
Design And Synthesis Of Novel Interacalator Based Chemical Nuclease
(Indian Institute of Science, 2007-03-08)Deoxyribonucleic acid and ribonucleic acid under physiological condition are polyanions composed of heterocyclic bases linked through sugar phosphate backbone. Due to Watson-Crick base pairing, DNA exists in double-helical ... -
Diffusion In Porous Solids : Void Disorder, Orientation And Rotation, Reaction And Separation, And Levitation Effect
(Indian Institute of Science, 2006-12-12)Diffusion in bulk has been well studied and our understanding may be said to be adequate if not complete. Similarly, surface diffusion has been investigated by a number of workers and a fair understanding of it has emerged. ... -
Experimental And Theoretical Studies On Jet Acoustics
(Indian Institute of Science, 2006-12-14)A systematic research on aeroacoustics conducted around the world for the last few decades has revealed various inherent characteristics of the jet noise radiation. However, a lot more needs to be done for the theoretical ... -
Feature transformation for speaker identification
The gradual automation of services and transactions that previously required human handling has led to a growing interest in biometrics, which are unique measurable traits of a human being used for automatic identity ... -
A Finite Element Investigation Of Brittle Fracture During Spherical Nanoindentation Of Thin Hard Films
(Indian Institute of Science, 2006-12-14)Hard ceramic films of micrometric thickness deposited on a soft metallic substrate have ushered in a new era in the fabrication of structural, tribological, microelectronic and optical components. The mechanical performance ... -
Genetic Programming Based Multicategory Pattern Classification
(Indian Institute of Science, 2005-02-22)Nature has created complex biological structures that exhibit intelligent behaviour through an evolutionary process. Thus, intelligence and evolution are intimately connected. This has inspired evolutionary computation ... -
IMAGINE : An Intelligent Electonic Marketplace
(Indian Institute of Science, 2007-01-16)In recent times, the Internet revolution has spawned numerous innovative enterprises-virtual companies, and electronic markets. Electronic markets (or digital markets) are scalable web-based platforms for buyers, sellers, ... -
