Response of Granular Materials Towards Blast Loading
Granular media, such as sand, soil, and rocks, are commonly encountered in various engineering and geotechnical applications, and their response to blast loading is of significant interest. In this master’s thesis, the ... -
On commuting isometries and commuting isometric semigroups
This thesis consists of two parts- commuting isometries and commuting isometric semigroups. In the first part, we study the Taylor joint spectrum for a pair of commuting isometries in certain cases. We show that the joint ... -
Electron Microscopy Investigations of Surface-modulated Nanomaterials for Electrocatalytic Applications
With advancement and increasing usage of technologies, the demand for energy is also growing. However, the limited and ever-depleting stock of natural gas and fossil fuels has necessitated for better solutions in energy ... -
Exploring End-of-Life Photovoltaic (PV) Panel as a Building Material: A Case of Crystalline Silicon PV
The renewable energy share in the energy mix worldwide is rising sharply to mitigate climate change, with Solar Photovoltaics (PV) carrying a large share of 3.6%. However, the end-of-life (EoL) management of decommissioned ... -
Multimodal sleep staging and diagnosis of sleep disorders
Sleep is not a single uniform state, but rather a cyclical pattern involving multiple stages such as rapid eye movement (REM) and non-REM (NREM stages N1, N2, and N3). Polysomnography (PSG) is considered as the gold standard ... -
Computational study of membrane driven secondary structural changes in proteins
Conformational changes in proteins, the most abundant biomolecule found in all living organisms, are ubiquitous and triggered by several factors essential for protein function. Protein conformational changes typically occur ... -
Discrete Velocity Boltzmann Schemes with Efficient Multidimensional Models
Traditional CFD algorithms have achieved a high degree of sophistication for modelling fluid flows in the past five decades. This sophistication can be seen clearly in one dimensional modelling, with a wide variety of ... -
Computational analysis of polymer nanocomposites across length scales
Polymer nanocomposites (PNC) exhibit excellent mechanical properties making them a promising material for several engineering applications. The enhancement in properties is primarily attributed to the toughening and ... -
Accurate Prediction of Enhancement Factors for Water Flow Through Boron Nitride Nanotubes
Water in nanoconfined spaces, such as nanotubes, exhibit anomalous yet intriguing behaviour compared to bulk water, a better understanding of which can enable us to realize a sustainable future. Nanotubes are atomically ... -
Resonant Metasurfaces for Mid-Infrared Photonics
The field of photonics offers a robust platform for efficient light-based technologies, directly impacting or serving as competent alternatives to address scientific problems. With the advent and advancement of micro-nano ... -
Investigating spin transport across magnetic insulators and their interfaces
Spin transport across magnetic insulator/heavy metal (MI/HM) interfaces has been a topic of interest in spintronics. The spin Seebeck effect (SSE) and spin Hall magnetoresistance (SMR) are two phenomena that have ... -
Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Comprehensive Investigation of the Mechanical Behavior of Nial-x (X=pt, Pd) Alloys: Effect of Composition, Orientation and Temperature
Gas turbine engines in the turbine section operate at temperatures exceeding 1300°C, which can cause high-temperature oxidation and reduce the lifespan of turbine blades. To counter this, thermal barrier coating (TBC) ... -
Understanding the role of Cysteine desulfurases in Mycobacterium tuberculosis physiology and pathogenesis
The Mycobacterium tuberculosis (Mtb) persistence inside the human host relies on successful adaptation to host-induced stresses such as reactive oxygen species (ROS), reactive nitrogen species (RNS), iron starvation, low ... -
Tailored Synthesis of Hexagonal Boron Nitride: Chemical Vapor Deposition and Next Generation Devices
The introduction of two dimensional (2D) materials in electronic device applications has provided a platform for several new device concepts and architectures. Hexagonal boron nitride (hBN) is the only insulator in the ... -
Index Coding over Noisy Channels and Some Applications
A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ... -
Design and Analysis of Random Access Protocols for Massive Machine-Type Communications
Massive machine-type communications (mMTC) is a 5G and beyond use case, where the network is expected to serve millions of devices per square kilometre. Typical mMTC devices include smart energy meters, pressure sensors, ... -
Towards metal additive manufacturing using alternate powders
Metal powders are predominantly produced using processes derived from atomization, which, apart from being highly energy intensive, are also inflexible and very material specific. These limitations are particularly acute ... -
Role of autophagy in reducing peripheral neuropathy and diabetic peripheral neuropathy
Peripheral neuropathy occurs when there is damage to the central or peripheral nervous system due to injury, disease, diabetes, or drug use. Endoplasmic reticulum (ER) stress is a distinct feature observed in neuropathic ... -
Evaluation of Cytogenotoxic Potential and Embryotoxicity of KRS Cauvery River Water in Zebrafish (Danio Rerio)
Pollutants and other forms of environmental stress (lifestyle and social behaviour) are of global concern due to significant adverse effects on human health. The term "exposome" has emerged as a concept in environmental ...
