1HNMR Study of Proton Glasses  Nuclear Spin Lattice Relaxation in BPxBPI(1x) and BPxGPI(1x)  Effects of Disorder on the Proton Group Dynamics
Mixed systems made from a combination of ferroelectric (FE) and antiferroelectric (AFE) compounds, exhibit various effects of disorder in different temperature regions. The kind of effects observed, depend on the technique ... 
3D Dosimetry using optical tomography and electronic portal images
The primary goal of this thesis is to develop techniques to quantify the radiation dose distributions used in radiotherapy for cancer treatment. It aims at developing a physically profound calculation model for the transit ... 
Absorption FlowCytometry for PointofCare Diagnostics
(20180525)Medical devices are used widely at every stage of disease diagnosis and treatment. To eradicate certain infectious diseases, the development of highly sensitive diagnostic tools and techniques is essential. The work reported ... 
Active matter: chirality, translational order, and interfaces
My PhD work is on chiral active matter with solid and fluid directions, dynamics of the interface of a nonconserved chiral order parameter in an active system, flocking on curved manifolds and fielddriven colloids in ... 
Activity induced phase separation and the emergence of liquid crystal phases in chiral and achiral systems, and development of an efficient method to compute the entropy of various liquid crystal phases
The phase behaviour of shapeanisotropic particles is an emerging field of research that gives rise to various liquid crystal phases. In this thesis, we explore various equilibrium and nonequilibrium properties of ... 
Adaptive Dielectric Thin Film Transistor : A SelfConfiguring Device for Low Power Electrostatic Discharge Protection
Large area and flexible electronic systems are widely used in applications such as displays, image sensors, wearable electronics, and energy harvesting systems. One of the fundamental functional blocks in these systems is ... 
Advanced Instrumentation for Detection of Defects and Diseases in Sericulture
Sericulture is the art of rearing silkworms for silk production. The matured silkworms will be spinning cocoons as a protective shield before they undergo metamorphosis. These cocoons are immersed in boiling water to soften, ... 
Advanced Light Sheet Volume Flow Cytometry (VFC/iLIFE) and Spectroscopy System for Cell Biophysics and Clinical Biology
Optical imaging is paramount for disease diagnosis and to access its progression over time. The developed light sheetbased optical flow imaging techniques, known as Volume Flow Cytometry(VFC/iLIFE), and related techniques ... 
Advanced Multifunctional Bulk Optical & Fiber Bragg Grating Sensing Techniques
(20170504)In this thesis work, a systematic quantitative study has been undertaken, on the performance of etched fiber Bragg Grating (FBG) sensors in the investigation of surface molecular adsorption in realtime; it is shown that ... 
AGN Feedback in Galaxy Clisters  Controlling Cooling Flows in Galaxy Clusters by Momentumdriven AGN Jets
Synopsis According to the hierarchical structure formation model, massive structures like galaxy clusters are formed due to the gravitational collapse of initial density perturbations and their subsequent mergers. ...

Algorithmic and Hardness Results for Fundamental FairDivision Problems
The theory of fair division addresses the fundamental problem of dividing a set of resources among the participating agents in a satisfactory or meaningfully fair manner. This thesis examines the key computational challenges ... 
An Algorithmic Approach To Crystallographic Coxeter Groups
(20130214)Coxeter group, named after H.S.M. Coxeter, is an abstract group that admits a formal description in terms of mirror symmetries. It turns out that the finite Coxeter groups are precisely the finite Euclidean reflection ... 
AllFiber Sensing Techniques For Structural Health Monitoring And Other Applications
(20100302)In this thesis, we explore the four aspects of fiber Bragg grating sensors: mathematical modeling of Fiber Bragg Grating response/spectral characteristics, fabrication using phase mask, application and interrogation. ... 
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 ... 
Analytic and Entire Vectors for Representations of Lie Groups
(20180101)We start with the recollection of basic results about differential manifolds and Lie groups. We also recall some preliminary terminologies in Lie algebra. Then we define the Lie algebra corresponding to a Lie group. In the ... 
Analytic Continuation In Several Complex Variables
(20140630)We wish to study those domains in Cn,for n ≥ 2, the socalled domains of holomorphy, which are in some sense the maximal domains of existence of the holomorphic functions defined on them. We demonstrate that this study ... 
Analytic Models, Dilations, Wandering Subspaces and Inner Functions
This thesis concerns dilation theory, analytic models, joint invariant subspaces, reproducing kernelHilbert spaces and multipliers associated to commuting tuples of bounded linear operators on Hilbert spaces. The main ... 
Analytical Formalism to Study the 21 cm Signal from Cosmic Dawn and Epoch of Reionization
The epoch of Cosmic Dawn and Reionization is one of the most important time periods of the universe when first sources of radiation like stars and galaxies were formed, and they changed the properties of their surrounding ...
