Analysis of Proportional Navigation Class of Guidance Law against Agile Targets
(20171212)Guidance is defined as the determination of a strategy for following a nominal path in the presence of onominal conditions, disturbances and uncertainties, and the strategy employed is called a guidance law. Variants of ... 
Charge Transport and PhotoPhysical Studies in Conjugated Polymers, Hybrid Nanocomposites and Devices
(20171212)The main motivation of this thesis is derived from the fact that physics of disordered systems like conjugated polymer has yet not achieved as concrete understanding as ordered and crystalline systems such as inorganic ... 
Compactness Theorems for The Spaces of Distance Measure Spaces and Riemann Surface Laminations
(20180218)Gromov’s compactness theorem for metric spaces, a compactness theorem for the space of compact metric spaces equipped with the GromovHausdorﬀ distance, is a theorem with many applications. In this thesis, we give a ... 
Continuous Beam of LaserCooled Ytterbium Atoms for Precision Measurements
(20171122)What if an elementary particle such as an electron had an intrinsic electric dipole moment (EDM)? Existence of such an EDM would be an indication of timereversal symmetry violation in the laws of Physics. The Standard ... 
The Cosmic Population of Extended Radio Sources : A RadioOptical Study
(20170927)This thesis presents studies of cosmic populations of extragalactic radio sources. The problems selected for this thesis are 1) the derivation of constraints on the emergence of new submJy populations at flux density below ... 
Crawling, Waving, Spinning : Activity Matters
(20171212)This thesis has been concerned with a few problems in systems driven at the scale of particles. The problems dealt with here can be extended and elaborated upon in a variety of ways. In 2 we examine the dynamics of a ﬂuid ... 
Crystal Structures of Sortase A from Streptococcus Penumoniae : Insights into DomainSwapped Dimerization. Crystal Structures of Designed Peptides : Inhibitors of Human Islet Amyloid Polypeptide (hIAPP) Fibrillization Implicated in Type 2 Diabetes And Those Forming SelfAssembled Nanotubes
(20170927)Sortases are cellmembrane associated cysteine transpeptidases that are essential for the assembly and covalent anchoring of certain surface proteins to the cell wall in Grampositive bacteria. Thus, they play critical ... 
Design, Development and Performance Analysis of Micromachined Sensors for Pressure and Flow Measurement
(20180218)Nowadays sensors are not limited only to industry or research laboratories but have come to common man’s usage. From kids toys to house hold equipment like washing machine, microwave oven as well as in automobiles, a ... 
Dilation Theory of Contractions and NevanlinnaPick Interpolation Problem
In this article, we give two different proofs of the existence of the minimal isometric dilation of a single contraction. Then using the existence of a unitary dilation of a contraction, we prove the `von Neumann's ... 
Electric, Magnetic and Magnetocaloric Studies of Magnetoelectric GdMnO3 and Gd0.5Sr0.5MnO3 Single Crystals
(20180510)After the prediction of magnetoelectric eﬀect in Cr2O3, in early 1960's, D. Asrov became the first to experimentally verify this phenomenon. After the pioneering work on magnetoelectric materials in 1960's and 1970's, the ... 
A Formal Proof of FeitHigman Theorem in Agda
(20180218)In this thesis we present a formalization of the combinatorial part of the proof of FeitHigman theorem on generalized polygons. Generalised polygons are abstract geometric structures that generalize ordinary polygons and ... 
Growth and Physical Properties of Biaxial Nonlinear Optical Crystals of Ascorbic Acid Family
(20180226)Saccharides, a class of organic materials, are potential candidates for nonlinear optical applications. Ascorbic acid is a sugar acid and is classiﬁed as a monosaccharide. The molecule of ascorbic acid has two chiral centers ... 
The Higgs Boson as a Probe of Physics Beyond the Standard Model at the Large Hadron Collider
(20180508)The nature of interactions of fundamental particles is governed by symmetries. These interactions are well described by an elegant and simple SU(3)c x SU(2)L x U(1)Y symmetric gauge theory that we call the Standard Model ... 
HighResolution Spectroscopy in Atoms Using Coherent Control
(20171026)The subject of this thesis is the study of coherent interaction of light with matter (atoms) to improve the precision measurements and techniques. Special attention is drawn to get the narrow subnatural electromagnetically ... 
Homogeneous Operators and Some Irreducible Representations of the Mobius Group
In this report, after recalling the definition of the M¨obius group, we define homogeneous operators, that is, operators T with the property '(T) is unitarily equivalent to T for all ' in the M¨obius group and prove some ... 
Hyperfine StructureMeasurement in Alkalimetal Atoms and Ytterbium Atom
(20180215)Atomic precision measurements provide a strong testing ground for new theoretical ideas and fundamental laws of physics. Measurement of the Lamb shift in the hydrogen atom is one of the best examples towards this it ...
