Study of radio emissions from clusters of galaxies: CD galaxies and the very steep spectrum sources
(a) An important conclusion regarding the probability of radio emission associated with the brightest galaxy in the centre of a cluster containing a VSSS (Very Steep Spectrum Source) can be drawn from the study of Table ... -
Analytic and numerical studies of neural network models of associative memory
In this thesis, we have used analytical and numerical methods to study the behaviour of neural network models for the storage, classification and associative recall of information. In Part A, we have studied a class of ... -
On the mismatch between predicted and measured frequencies in model testing
Mathematical models verified against ground test data are often necessary in the aerospace industry. They are used for predicting system performance in the intended as well as in any altered operating environments. They ... -
Transient and steady-state response of second and higher order non-linear systems
The present investigation deals with the transient flnfl steady-state response o£ second and higher order nonlinear systems. The method of attack consists of the ultraspherical polynomial approximation and the weighted ... -
Lay Tracks : New approach to automated quadrilateral mesh generation using MAT
This thesis describes Lay Tracks, a new mesh generation algorithm to automatically generate an all quad mesh using the medial axis transform (MAT). LayTracks combines the merits of two popular direct techniques for quad ... -
Some approximate methods of analysis of Non-Linear Dynamical systems
The present investigation concerns some approximate methods of analysis in the area of non-linear oscillations. The analysis includes the steady-state as well as the transient response of non-linear systems. In both cases, ... -
Assessment of factors influencing production and marketing of groundnut and sunflower in Peninsular India
Oilseeds are an important component in India’s agriculture and annually around 24 m. ha are planted to oilseeds with a production of around 24 m. t. In spite of significant growth achieved in oilseed production and ... -
Prediction of bond ratings using statistical and neural networks techniques
In this research work, an attempt has been made to develop a comprehensive statistical and neural networks models lo predict the ratings of Indian manufacturing sector firms based on their financial characteristics. This ... -
Acquisition of technological capability and economic performance in clusters : a study of Belgaum and Coimbatore small scale foundries
Promotion of small-scale industries (SSIs) has been given a lot of importance in developing countries because of the many virtues small industries have, such as, the potential to generate employment, nurturing of ... -
Testing arbitrage pricing theory for the Indian market
Our main objective was to test whether the APT hypotheses as developed by Roll and Ross[ I 980] and further clarified by Cho and Taylor[1987] holds for the Indian market. We also investigate the impact of increasing the ... -
Evaluation of policy parameters, uncertainties and risks in build, operate and transfer (BOT) projects for transport infrastructure development
There is a growing recognition that inadequate transport infrastructure in any country is an impediment to its industrial and economic progress. Governments worldwide are increasingly attempting to involve the private ... -
A Study of an R&D team in an Indian research organization : an ethnographic approach
The research reported in this thesis has attempted to provide a suggestive ethnographic case study of an R&D team in a government-sponsored power research institute in Southern India. This case study has tried to demonstrate ... -
Construction of market index, efficient portfolios and a test for capital market efficiency
Individual investors in the capital market often wish to hold portfolios that "follow the market" but consist of only a small number of scrips. This study addresses the problem of designing a compact portfolio of scrips ... -
Epigenetic repression of stemness genes by the TCP/KNOX-II transcription factors in simple leaf development of Arabidopsis
Leaves are initiated as primordia at the flanks of the shoot apical meristem. Primordia in the simple-leaved species such as Arabidopsis produce single lamina, whereas those in compound-leaved species such as tomato ... -
Understanding failure in heterogeneous materials
The failure of heterogeneous materials is a practical problem that occurs in several diverse applications. Material heterogeneity can arise from porosity (e.g., due to some processing history), variation in continuum-scale ... -
Protecting Deep Learning Models on Cloud Platforms with Trusted Execution Environments
Deep learning is rapidly integrated into different applications, from medical imaging to financial products. Organisations are spending enormous financial resources to train deep learning models. Often, many organisations ... -
Computations in linear algebra: a new look at residue arithmetic.
The dissertation deals with error-free and approximate computations of some problems in linear algebra, with an emphasis on a modified residue arithmetic developed here. It is divided into five chapters:Chapter 1 The ... -
Numerical study of natural convection boundary layer flows
This thesis presents a numerical study of some laminar natural convection boundary layer flows in isothermal and non-isothermal media. It consists of five chapters. The first is an introductory one; the remaining four are ... -
Boundary element method applied to fluid flow problems
This research work is a study of fluid flow problems by the Boundary (Finite) Element Method. The widely used Finite Element Method has the advantages of its flexibility in choosing the shape and size of the elements, the ... -
Ergodic and adaptive control of markov processes.
We address the problem of controlling two classes of Markov processes, viz., Markov chains and diffusion processes. Our main goal is to minimize a long-run average cost criterion (or ergodic cost criterion) associated with ...
