Asymptotic Lower Bound for Quasi Transitive Codes over Cubic Finite Fields
(20180714)Algebraic geometric codes were first introduced by V.D.Goppa . They were well recognized and developed by Tsfasman, Vladut and Zink because they have parameters better than GilbertVarshmov bound and thus giving rise to ... 
The CaratheodoryFejer Interpolation Problems and the VonNeumann inequality
(20180530)The validity of the vonNeumann inequality for commuting $n$  tuples of $3\times 3$ matrices remains open for $n\geq 3$. We give a partial answer to this question, which is used to obtain a necessary condition for the ... 
Crystal Structure Analysis of a (B/a)8TIM Barrel Enzyme and Its Mutants : Insights into the Role of Interactions Between Termini in Influencing Protein Stability. Experimental and Computational Study of ProteinSurfacePockets Occluded by Tryptophan SideChains
Xylanases (EC 3.2.1.8) are glycosyl hydrolases that catalyze the hydrolysis of internal β1,4 glycosidic bonds of xylan backbones, and have potential economical and environment friendly applications in the paper pulp, food, ... 
Design, Development and Performance Study of Microneedle & Micropumpbased Transdermal Drug Delivery System
Transdermal drug delivery is the most preferred drug delivery method, due to its high efficiency and less side effects. In conventional transdermal drug delivery, the delivery of macromolecular drugs (ex: Insulin, vaccines ... 
Driven Granular and Softmatter : Fluctuation Relations, Flocking and Oscillatory Sedimentation
(20180611)Active matter refers to systems driven out of thermal equilibrium by the uptake and dissipation of energy directly at the level of the individual constituents, which then undergo systematic movement in a direction decided ... 
Dynamical Properties of Families of Holomorphic Mappings
(20180608)Thesis Abstract In the first part of the thesis, we study some dynamical properties of skew products of H´enon maps of C2 that are fibered over a compact metric space M . The problem reduces to understanding the dynamical ... 
Dynamics of GlassForming Liquids and ShearInduced Grain Growth in Dense Colloidal Suspensions
(20180619)The work presented in this doctoral thesis employs colloidal suspensions to explore key open problems in condensed matter physics. Colloidal suspensions, along with gels, polymers, emulsions and liquid crystals belong to ... 
Electrical Spin Injection and Detection Using Oxide Magnetic Material Fe3O4
Since the proposal of DattaDas transistor, area of spin injection and detection is in the spotlight for the last decade. Intense research in this field has successfully tackled many issues like conductivity mismatch. Use ... 
Electrical Transport in Si:P and Ge:P δdoped Systems
(20180730)Doped semiconductor systems have for decades provided an excellent platform to study novel concepts in solid state physics such as quantum hall eﬀect, metaltoinsulator transition (MIT), weak localization and many body ... 
Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rareearth manganites with the general formula T1xDxMnO3 where `T' is a trivalent rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion, e.g Ca2+; Sr2+;Ba2+ etc. display various ... 
Establishing Super and SubChandrasekar Limiting Mass White Dwarfs to Explain Peculiar Type La Supernovae
(20180623)A white dwarf is most likely the end stage of a low mass star like our Sun, which results when the parent star consumes all the hydrogen in its core, thus bringing fusion to a halt. It is a dense and compact object, where ... 
Fiber Bragg Grating Based Sensing Devices for Novel Applications in Biomedical and Engineering Fields
Sensors have been an integral part of human life. Various sensor technologies have contributed in their own ways to fulfill specific requirements for aiding human beings. In this context, fiber optic sensors have several ... 
Flocks, Flow and Fluctuations in Inanimate Matter : Simulations and Theory
In this thesis we study a novel softmatter 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 ... 
The Green's Function, the Bergman Kernel and Quadrature Domains in Cn
(20180608)In the ﬁrst part of this thesis, we prove two density theorems for quadrature domains in Cn ,n≥2. It is shown that quadrature domains are dense in the class of all product domains of the form D×Ωwhere D⊂Cn−1 is a smoothly ... 
Growth and Studies of Phase Transitions in Multifunctional Perovskite Materials
(20180611)Crystal growth and characterization of few multifunctional materials with perovskite (ABX3) structure are discussed in this thesis. Efforts were made to modify the magnetic and electric behaviour of these materials by ... 
Higher Spins, Entanglement Entropy And Holography
(20170821)The idea of holography [1, 2] finds a concrete realization in form of the AdS/CFT correspondence [3, 4]. This duality relates a field theory with conformal symmetries to quantum gravity living in one higher dimension. In ... 
Inferences on Structure and Function of Proteins from Sequence Data : Development of Methods and Applications
(20180723)Structural and functional annotation of sequences of putative proteins encoded in the newly sequenced genomes pose an important challenge. While much progress has been made towards high throughput experimental techniques ... 
Lessons for Gravity from Entanglement
One of the recent fundamental developments in theoretical high energy physics is the AdS/CFT correspondence [1, 2, 3, 4] which posits a relationship between Quantum Field Theories (QFT) in a given dimension and String ... 
LpAsymptotics of Fourier Transform Of Fractal Measures
(20180608)One of the basic questions in harmonic analysis is to study the decay properties of the Fourier transform of measures or distributions supported on thin sets in Rn. When the support is a smooth enough manifold, an almost ...
