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 ... -
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 ... -
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 ... -
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 ... -
some nonlinear surface wave propagation problems
This thesis contains the results of investigations of some nonlinear surface wave propagation problems. It is divided into six chapters, of which Chapter I is the general introduction and the concluding remarks constitute ... -
Some results on finite section linear integral operators
This thesis deals mainly with some spectral properties of finite section linear integral operators from L2[0,t]L^2[0,t]L2[0,t] into itself, defined as Ttf(x)=?0tK(x,y)f(y)?dyT_t f(x) = \int_0^t K(x,y) f(y) \, dyTt?f(x)=? ... -
Enumerative considerations of SDR's and latin rectangles
The art of counting is interesting but often 120000103 a difficult task. It requires computational skills^ ' .. ability to recognise similar patterns and a little mastery of general principles and simplification ... -
Some boundary value problems in elasticity with and without magnetic field
In our paper, in order to solve the problem we need the knowledge of three analytic functions 4>(z), and f^(z).. In the case of plane magneto-elasticity we arrive at a homogeneous biharmonic equation, as is the case ... -
Development of Novel Deep Learning Models for Quantitative Medical Image Analysis
Medical imaging provides a non-invasive way to visualize tissues and diseases, enabling both qualitative and quantitative assessments that are needed in diagnosing and monitoring a wide range of conditions. Modalities ... -
Exact analytic solutions for some classes of partial differential equations
Exact solutions of linear partial differential equations with variable coefficients and those of nonlinear partial differential equations are dilEcult to obtain. The present thesis attempts to extend the existing methods ... -
Fredholm determinant and decay properties of eigenvalues of hilbert-schmidt integral operators
In this thesis, some properties of the eigenvalues of Hilbert-Schmidt integral operators (briefly H-S operators) are investigated. This thesis consists of three chapters. In the first two chapters, H-S operators of the ... -
Homogenization of partial differential equations in perforated domain
Theory of homogenization in Partial Differential Equations has a variety of applications in many branches of science. In the present thesis, we study the homogenization of certain boundary value problems in a periodically ... -
Some analytic studies on generalized burgers equations
Thesis Summary: Analysis of Generalized Burgers Equations This thesis analyzes a class of nonlinear parabolic equations known as generalized Burgers equations. The study combines analytical techniques with numerical ... -
Finite section convolution integral operators structure of resolvent and solution of first kind equations
This thesis investigates the structure of the solutions of Fredholm integral equations of the first and second kinds with convolution kernels on finite intervals and some of its applications. The thesis is divided into ...
