Hermitian Metrics and Singular Riemann Surface Foliations
The main aim of this thesis is to understand curvature properties of a given hermitian metric by restricting it to the leaves of a suitable singular Riemann surface foliation. We will specifically consider the complete ... -
Reliability based analysis and design of slopes and tunnels in rock mass
Structures in rock mass such as slopes and tunnels form an important segment in the infrastructure development of a country. Rock mass consists of intact rock matrix with numerous discontinuities that can be represented ... -
Industrial Structure, Productivity, Growth and Inflation: A Study on Interrelationships, Causality and Effects
India is one of the largest and fastest-growing economies in the world. Its growth is supported by the vibrant manufacturing sector which has strong linkages with other sectors. The manufacturing sector plays a pivotal ... -
Speaker verification using whispered speech
Like neutral speech, whispered speech is one of the natural modes of speech production, and it is often used by speakers in their day-to-day life. For some people, such as laryngectomees, whispered speech is the only ... -
Sequential Controlled Sensing to Detect an Anomalous Process
In this thesis, we study the problem of identifying an anomalous arm in a multi-armed bandit as quickly as possible, subject to an upper bound on the error probability. Also known as odd arm identification, this problem ... -
Advances in High Dynamic Range Imaging Using Deep Learning
Natural scenes have a wide range of brightness, from dark starry nights to bright sunlit beaches. Our human eyes can perceive such a vast range of illumination through various adaptation techniques, thus allowing us to ... -
Statistical Network Analysis: Community Structure, Fairness Constraints, and Emergent Behavior
Networks or graphs provide mathematical tools for describing and analyzing relational data. They are used in biology to model interactions between proteins, in economics to identify trade alliances among countries, in ... -
Band-matched transport layers and intrinsically stable perovskite solar cells for application to perovskite Si tandem cells
Hybrid perovskite/silicon tandem solar cells offer low-cost alternatives to the commercially established silicon solar cells. In this thesis, we present the material and device optimizations of the subcells that can be ... -
Nodal sets of random functions
This thesis is devoted to the study of nodal sets of random functions. The random functions and the specific aspect of their nodalset that we study fall into two broad categories: nodal component count of Gaussian Laplace ... -
Asymptotic Analysis of Multi-scale, Multi-loop Feynman Diagrams
It is very challenging to solve multi-scale, multi-loop Feynman diagrams analytically. The presence of different kinematic scales makes the computation of Feynman diagrams very difficult, sometimes impossible to get the ... -
Design and Development of Proteasome Activity Modulators: A Novel Strategy for the Treatment of Diabetes Mellitus
Design and Development of Proteasome Activity Modulators: A Novel Strategy for the Treatment of Diabetes Mellitus Abstract The ubiquitin-proteasome system (UPS) is the major pathway for degradation of the intracellular ... -
Role of Lysyl oxidase in TGF-beta-induced Fibroblast Activation and Cancer-Associated Fibroblast-mediated Breast Cancer Progression
Cancer-associated Fibroblasts (CAFs) are a dominant cell type of the breast cancer microenvironment and are proposed to be involved in metastatic progression. TGF-β has been reported to influence fibroblast to myofibroblast ... -
Multiscale Simulation of Nucleic Acid Nanostructures
Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ... -
Use of Human Induced Pluripotent Stem Cells as a Model to Study Primary Microcephaly
The aim of this study was to use human induced pluripotent stem cells (hiPSC) to understand key steps of neuronal differentiation and to model the human brain developmental disorder, primary microcephaly (MCPH). MCPH is a ... -
Eutectic microstructures: Role of interfacial energy anisotropy and diffusivities
Eutectic alloys find a wide application in industrial cast alloys, solder alloys, and in the emerging field of functional materials. Apart from technological applications, multiphase eutectic alloys have also received keen ... -
Understanding the regulation of translation and replication of Coxsackievirus B3 RNA by host RNA binding proteins
Coxsackievirus B3 (CVB3) is an enterovirus, with a positive-sense single-stranded RNA genome. The genome contains a single open reading frame (ORF) flanked by untranslated regions (UTR) at the 5’ and 3’ ends. The viral ... -
Versatile sensing platform using silicon photonic microring resonators
Measurement of refractive indices of liquids and thin films can play an important role for chemical analysis in the fields of healthcare and biomedical research. There is a requirement of miniaturized refractive index ... -
Time Domain Spectral Finite Element Simulation of Ultrasonic Wave Propagation in Composite with Defects
Ultrasonic guided wave-based detection of structural defects or damages is one of the promising methods for structural health monitoring (SHM). A significant proportion of structural elements in an aircraft structure and ... -
An Empirical Study of Transformative Learning Resulting Due to Profession Change
A career choice may emerge or be adopted due to personal interest or to balance a range of factors like familial influences, educational qualifications and economic considerations. Once a choice has been made, some follow ... -
Support Recovery from Linear Measurements: Tradeoffs in the Measurement-Constrained Regime
In this thesis, we study problems under the theme of discovering joint sparsity structure in a set of high-dimensional data samples from linear measurements. Our primary focus is on the regime where the number of samples ...
