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 ... -
Deeply Scaled InAlN/GaN-on-Silicon High Electron Mobility Transistors for RF Applications
Wide bandgap gallium nitride (GaN) based high electron mobility transistors (HEMTs) are promising candidates for next-generation radio frequency (RF) power amplifier applications owing to high electron saturation velocity ... -
Climate-resilience of Dwellings in Transition and the Thermal Behaviour of their Inhabitants
Thermal comfort is critical for the well-being, and productivity of the inhabitants. Traditional dwellings constructed using local, low-carbon materials have for decades provided comfortable indoor thermal environment to ... -
Novel Algorithms for Improving Agricultural Planning and Operations using Artificial Intelligence and Game Theory
This dissertation work is motivated by the critical need to address a perennial global problem, namely, how to mitigate the distress of the small and marginal agricultural farmers in emerging economies. Key reasons behind ... -
Experimental and computational approaches to understand collective behaviors of bacterial pathogen Pseudomonas aeruginosa
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen, estimated to account for 15-20% of hospital-acquired infection-related deaths around the globe in a year. This bacterium exhibits two distinct collective ... -
A Study of Factors Influencing Need for, Mode of and Sustainability of New Urban Mobility
Globally, we are observing a paradigm shift in urban mobility enabled by the exponential growth in information and communication technologies (ICTs) leading to profound transformation from traditional mobility to other ... -
Micro-carriers mediated bacteriophage delivery for targeting intracellular Mycobacterium tuberculosis infection and TB prevention
Tuberculosis (TB) is a debilitating infectious disease that afflicts 10 million people every year. Treatment is particularly challenging due to prolonged treatment duration (4-6 months) consisting of an oral regimen of 4 ... -
Functionalized Nanomaterial and Metallocycle for Selective Antibacterial, Diagnosis, and Anti-cancer Activity
The evolution of drug resistant bacteria has become a severe threat to public health globally. The misuse of conventional antibiotics has led to the development of multi-drug resistant bacteria. Even though antibiotics ... -
Metal-Organic Framework (MOF) Compounds: Synthesis, Structure and Catalytic Studies
The metal-organic framework (MOF) compounds exhibit interesting developments in coordination chemistry, materials science and other branches of chemistry. These compounds have potential applications in diverse fields ... -
Synergistic Effect of Electromagnetic Forces on the Failure of Pre-Cracked Thin Metallic Conductors
Finite element method (FEM) simulations were performed, and distributions of current density, electromagnetic force, and stress fields due to the self induced electromagnetic forces were evaluated in a pre-cracked thin ... -
Orbital Engineering Directed Electronic Structure Studies: Design of Pseudo 𝜋 Aromatic Molecules, Borophenes and Borophites
The many ways of using three-membered rings as a design element in molecules and borophenes (2D sheets of boron) will be presented. The underlying design principles require constructing and manipulating molecular orbitals ... -
Algortihms for Individual and Collective Fairness Measures
The problem of fair allocation has been a central topic in economic theory, and the literature on fair division has provided fundamental insights on how to allocate resources among agents in a fair manner. By drawing upon ...
