Finite Element Analysis of Interior and Boundary Control Problems
(2018-06-18)The primary goal of this thesis is to study finite element based a priori and a posteriori error estimates of optimal control problems of various kinds governed by linear elliptic PDEs (partial differential equations) of ... -
Finite Element Analysis of Optimal Control Problems Governed by Certain PDEs
The primary goal of this thesis is to study finite element based \textit{a priori} and \textit{a posteriori} error analysis of optimal control problems of various kinds governed by linear elliptic PDEs of second order. ... -
First Principles Study of Oxides : Bulk, Interfaces and Defects
In the recent years, oxides have been the focus of numerous theoretical and experimental studies. This is because of a wide variety of exotic physical phenomenon, such as multiferroicity, charge ordering, metal-insulator ... -
First principles study of the structural, electronic, elastic, mechanical, thermal, and vibrational properties in pyrochlores and temperature-dependent phonon properties in pyrochlores and SrTiO3 perovskite
In this thesis, first-principles density functional theory (DFT) calculations are used to study the structural, electronic, elastic, mechanical, and thermal properties in a series of pyrochlore materials. The vibrational ... -
Flavor and Dark Matter Issues in Supersymmetric Models
(2018-04-06)The Standard Model of particle physics attempts to unify the fundamental forces in the Universe (except gravity). Over the years it has been tested in numerous experiments. While these experimental results strengthen our ... -
Flocks, Flow and Fluctuations in Inanimate Matter : Simulations and Theory
In this thesis we study a novel soft-matter system that imitates motility. Our system consists of a few asymmetrically tapered brass rods and aluminium beads which are confined between two vertically shaking plates. The ... -
Flow Induced Instabilities, Shear-Thickening And Fluctuation Relations In Sheared Soft Matter
(2016-09-09)In day to day life we encounter many different materials which are intermediate between crystalline solids and simple liquids that include paints , glues , suspensions, polymers, surfactants, food and cosmetic products and ... -
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ... -
Fluctuations in quantum transport in topological insulators
Topological insulators (TIs) belong to a new class of materials characterized by linear surface states, which emerge in the bulk band gap due to non-trivial topology of the band structure. These surface states have various ... -
Fluid Flow And Electrochemical Bias Induced Effects In Carbon Nanotubes And Raman Studies On Iron Perovskites
(2011-09-30)This thesis is divided into two parts; the first part presents results on the effect of the flow of fluids and electrochemical bias on single walled carbon nanotubes (SWNT). Issues pertaining to the entry of water into the ... -
Force and Shape Estimation using Fiber Bragg Grating Sensors for Assistance in Minimally Invasive Diagnostic and Surgical Procedures
Fiber Bragg Grating (FBG) sensors have become increasingly popular for applications in biomedical engineering. Amongst these, use of FBGs in ‘smart instruments’ for minimally invasive diagnostic and surgical procedures ... -
A Formal Proof of Feit-Higman Theorem in Agda
(2018-02-18)In this thesis we present a formalization of the combinatorial part of the proof of Feit-Higman theorem on generalized polygons. Generalised polygons are abstract geometric structures that generalize ordinary polygons and ... -
The Formation and Evolution of Bars, and Its Impact on Galaxy Dynamics
In this thesis we have studied bar formation and evolution using N-body simulations. We have focused on the effect of bulge mass and concentration on bar formation and evolution, and derived a new bar formation criterion. ... -
Fourier Analysis On Number Fields And The Global Zeta Functions
(2014-08-04)The study of zeta functions is one of the primary aspects of modern number theory. Hecke was the first to prove that the Dedekind zeta function of any algebraic number field has an analytic continuation over the whole plane ... -
Fourier coeffcients of modular forms and mass of pullbacks of Saito–Kurokawa lifts
In the first part of the talk we would discuss a topic about the Fourier coefficients of modular forms. Namely, we would focus on the question of distinguishing two modular forms by certain ‘arithmetically interesting’ ... -
