Van der Waals Heterojunctions for Emerging Device Applications
Low-dimensional systems are an exciting platform for exploring new physics and realizing novel devices. The intriguing features, such as the existence of strongly bound multiparticle complexes and thickness-dependent band ... -
Space-Time Gauge Theories for Continuum Modelling of Viscoplasticity, Damage And Electro-Magneto-Mechanical Phenomena in Solids
Over the years, sustained research efforts have aimed to understand the material behaviour under a broad range of response regimes, especially from micromechanical or phenomenological perspectives — via both continuum ... -
Data Efficient Domain Generalization
Deep neural networks has brought tremendous success in many areas of computer vision, such as image classification, retrieval, segmentation , etc. However, this success is mostly measured under two conditions namely (1) ... -
Turbulent Free Moist Convection over Horizontal Surfaces
The heat and moisture loss from water surfaces are important in many natural and industrial systems. For example, the natural water cycle where water evaporates from the lakes, rivers, and seas, rises in the atmosphere, ... -
Systems biology approach to dissect Salmonella-host interactions
Systems understanding of the biological data is required to capture the complex biochemical information when a pathogen interacts with its host. Such interactions are dynamic and complex, especially because various components ... -
Methods for Improving Data-efficiency and Trustworthiness using Natural Language Supervision
Traditional strategies to build machine learning based classification systems employ discrete labels as targets. This limits the usefulness of such systems in two ways. First, the generalizability of these systems is limited ... -
Multi-Armed Bandits – On Range Searching and On Slowly-varying Non-stationarity
Multi-Armed Bandits (MAB) is a popular framework for modelling sequential decision-making problems under uncertainty. This thesis is a compilation of two independent works on MABs. 1. In the first work, we study a ... -
Investigation of Structural relaxation in IV - V -VI Chalcogenide glasses for Infrared applications
Chalcogenide glasses are well known for their application in infrared transmission and sensing. These glasses are usually prepared by quenching the melt. The arrangement of atoms in the liquid state gets arrested into ... -
Study of gas-fine flow in a packed bed with an application to the ironmaking blast furnace
The iron and steelmaking industry uses coal as the primary reducing agent. The carbon that is the major component of coal is finally released into the environment as carbon dioxide. One of the effective ways to reduce the ... -
Studies on the promoter specificity determinants and modulators of the prokaryotic transcription machinery
Bacteria adapt to a wide range of environmental conditions by synchronizing transcription with changes in the extracellular environment. This is achieved by the synchronized action of two-component systems, Extra Cytoplasmic ... -
Correlation between Morphology, Microstructure and Corrosion Behaviour of Nickel-Phosphorous (Ni-P) Based Electrodeposited Coatings
The Ni-P alloy coatings are widely studied due to their superior mechanical and tribological properties. Ni-P coatings are also considered to be a viable alternative to the chromium (Cr) coatings which utilize environmentally ... -
Enhancement in corrosion resistance of selected high entropy alloys by incorporation of carbon nanotubes
High entropy alloys (HEAs) have attracted considerable interest due to their remarkable structural and functional properties. HEAs generally contain 5–13 principal elements with the concentrations of each component lying ... -
Raman Spectroscopy Instrumentation and Its Application in Deep Tissue Imaging
Raman spectroscopy is based on inelastic scattering, which gives molecular information. Due to its weak nature, for a long-time Raman spectroscopy was limited to only study of molecular interactions, but with the advancement ... -
Design of Compact Antennas With Metasurface for Wideband and Wireless Applications
An antenna is one of the essential elements in a wireless system, that converts the guided waves in an electronic circuit to unguided waves in the air and vice versa. They are often designed according to the specifications ... -
Development of 3D model and understanding translational regulation of breast cancer
Breast cancer is the most common cancer among women in India and worldwide. It is a highly heterogeneous disease caused by several genetic and epigenetic alterations in mammary epithelial cells. Both inter- and intra-patient ... -
Broadband Millimeter-Wave CMOS Transceiver for 5G Mobile Communication and Radar-Based Sensing
To meet the ever-growing demand for higher data rates in communication networks and higher range and velocity resolutions in automotive radar sensors, fifth-generation (5G) new radio (NR) transceivers and radars used in ... -
Role of Sirt2 in Stress-induced Muscle Atrophy
Skeletal muscle is one of the essential organs in our body, responsible for various functions such as locomotion, transport, protein storage, and thermoregulation. Under certain pathological conditions, there is a reduction ... -
Investigation of anticancer compounds in the natural productome of marine algae associated-endophytic fungi
Cancer is one of the leading causes of death worldwide. Owing to the complex ways in which this disease develops, there is a constant demand for new drugs. Natural products have delivered great promise in inspiring ... -
Differential Regulation of Calcium Dependent Phase Separation and Modular Assembly of Sap97/Hdlg Enriched Molecular Complexes
