Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Platinum overlayers characterization and fabrication via self-terminating electrodeposition
Hydrogen is considered a promising alternative fuel for the future. However, despite its perception as a “zero-carbon” energy carrier, fossil fuels remain the primary feedstocks for hydrogen production, involving significant ... -
Some investigations into algebraic and geometric properties of Feynman integrals and related topics
We describe our investigations into various formal properties of Feynman integrals and of scattering amplitudes obtained from studying algebraic structures. There are variety of ways to study these properties. Out of which, ... -
The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
The Cahn-Hilliard-Navier-Stokes (CHNS) framework has found extensive applications, across diverse length and time scales, for multi-phase flows. In this thesis, we demonstrate that this framework offers a robust theoretical ... -
Studies of Pyridoneimine in Site-Selective Functionalization of Carbohydrates and in Multivalent Phenomenon
Carbohydrates are functionally rich biomolecules with multiple hydroxy functionalities. As a result, the most often practiced chemical route is to install protecting groups that permit selective functionalization at the ... -
Understanding protein structural excursions using residue networks and implications on biological function
The information required for a protein structure to fold into the native conformation is encoded in its sequence. Studying protein structures help to understand their biological function. Molecular interactions between ... -
Improved Derivative-based Regularizations for Imaging Inverse problems
Images undergo degradation during the capturing process due to physical limitations inherent to the capturing devices. Addressing this degradation and recovering high-quality images constitute the image recovery problem, ... -
Venomics of Medically Important yet Neglected Elapid Snakes of India and the Antivenomic Potential of Plant Extracts
India is considered the world's snakebite capital, where over 58,000 snakebite fatalities are registered annually. Most bites are primarily attributed to four snake species: the spectacled cobra (Naja naja), common krait ... -
Understanding the interaction mechanism of bacterial virulence factors and effector proteins with host lipid membrane using single particle cryo-electron microscopy
Pathogenic bacteria employ an array of biological macromolecules and cellular structures that help in the initiation and progression of disease in host organism. These ‘virulence factors’ can either be secreted by the ... -
Role of Sirtuin 2 in the development of tissue fibrosis
Wound healing is a crucial physiological process required for the healthy lifespan of an organism. Dysregulation in the process of wound healing leads to the production of excess extracellular matrix leading to fibrosis. ... -
An Explainable Hierarchical Class Attention Model for Legal Appeal Automation
Judicial systems worldwide are overburdened due to the limited number of legal professionals. The digitization of legal processes has resulted in abundant legal data, paving the way for the development of legal automation ... -
Flux Rate Controlled Harmonic Filtering of Integrated Magnetic-Based Isolated-Inverter Topologies and Dynamically Variable Inductors
An intermediate filtering stage is mandatory to deliver smooth sinusoidal output voltage across the load. Several multilevel and modular multilevel-based inverter topologies are reported in the literature to reduce the ... -
Some Aspects of Weighted Kernel Functions on Planar Domains
The broad aim of this thesis is to study some aspects of weighted kernel functions. In particular, this thesis has been driven by three principal goals: First, to study the boundary behaviour of weighted Bergman kernels. ... -
Frequency Domain Photoacoustic Signal Analysis for Temperature Sensing
Monitoring temperature in biological tissue is vital for different therapy applications like photo-thermal therapy, high-intensity focused ultrasound therapy, etc. Photoacoustic imaging has been used for volumetric temperature ... -
Performance Analysis of Orthogonal Time Frequency Space Modulation in High-Doppler Channels
Next generation wireless systems are envisioned to offer dependable and consistent user experience across a wide range of environments, including high-mobility scenarios involving high-speed trains, aircrafts, and ... -
A co-kurtosis tensor based featurization of chemistry for scalable combustion simulations
For turbulent reacting flow systems, identification of low-dimensional representations of the thermo-chemical state space is vitally important, primarily to significantly reduce the computational cost of device-scale ... -
Interfacial oscillations and atomization of liquid jets from non-circular orifices
Understanding the flow behaviour of liquid jets discharging from orifices is essential for several applications such as fuel spraying, ink-jet printing, aerosol devices in pharmaceutical industries, micro-machined fuel ... -
Paper-Based Point-of-Care Diagnostic Tools: Electrokinetic Nucleic Acid Extraction and Saliva-Based Glucose Detection for Diabetes Monitoring
Currently, we face a global challenge posed by the dual burden of chronic diseases such as diabetes and infectious diseases such as tuberculosis (TB). Low-and middle-income countries are disproportionately overburdened by ... -
Low–Speed Impact Mechanics and Fragmentation of Wooden Panels: Characterization of Indian Woods
Low–speed impact (LSI) of brittle structural panels by rigid bodies causes significant damage, evident in familiar scenarios like the breaking of monolithic and laminated glass panes due to stone pelting, punching a hole ...
