Studies on Fluid-Structure Interactions in Hypersonic Flow
Fluid-structure interaction (FSI) represents a critical area of research in aerospace engineering, particularly in the hypersonic flows where aerodynamic and thermal loads significantly impact structural integrity and ... -
Liquefaction response of the sand reinforced with 3D printed geocells
Geocells are one of the most widely used geosynthetics, owing to their three-dimensional interconnected cellular structure that allows immediate support to heavy loads and provides high lateral confinement and wider ... -
Modulating Waveform Generation for Split-Phase Induction Motor Drives and Discrete Modelling of Switched Reluctance Motor Drives
The thesis focuses on the areas for improvement in non-permanent magnet-based electric drives, such as the asymmetrical six-phase (or split-phase) induction motor and the switched reluctance motor drives. In the first ... -
Optimizing Light Absorption and Nanomorphology in Organic Solar Cells and Near-IR Photodetectors with Ternary Blend Approaches
Solution-processed Organic Solar cells (OSCs) are a promising renewable energy solution due to their solution-processable roll-to-roll fabrication, semitransparency, lightweight, and flexibility. Significant efforts have ... -
Electrical Transport and Point Contact Spectroscopy in Core-Shell Bimetallic Nanostructures
An extensively pursued strategy for realizing new materials is the creation of interfaces between two similar or dissimilar systems, which can invoke multiple processes like electronic reconstruction, strain-induced ... -
Breaking Symmetry – Organocatalytic Enantioselective Synthesis of Natural and Unnatural Ladderanes
Architecturally unique compounds produced by nature have remained a source of inspiration for organic chemists. Ladderane phospholipids (such as [5][3]PC and [3][3]PC), isolated in the year 2002 from anaerobic ammonium oxidizing ... -
Passive control and intermittent dynamics of the precessing vortex core oscillation in swirl flows
Swirl is used in modern gas turbine combustor nozzles to achieve reliable flame stabilization and efficient fuel-air mixing. The swirl component in the nozzle jet flow induces an axial vortex. At high swirl intensities, ... -
Impact of Groundwater Level Fluctuations on In-Situ Soil Properties using Automated Wave Detection Methods
Understanding the impact of groundwater level fluctuations on soil properties is crucial in geotechnical engineering, as it influences soil strength, stiffness, and stability. Dynamic soil properties such as Poisson's ... -
The benefits and costs of flexible alternative reproductive tactics in Oecanthus henryi
Alternative reproductive tactics (ARTs) are distinct phenotypes that individuals of a species use to maximize reproductive success. This thesis investigates the persistence and adaptive value of flexible ARTs in male tree ... -
Sub-mesoscale modeling framework for woven fabrics using VAM-based geometrically-exact beam model
In this work, a novel sub-mesoscale model of woven fabrics is developed using nonlinear finite element methods. The main aim of the work is to develop a framework for modeling woven fabrics. The yarns are modeled as beam ... -
GPU-Accelerated Quantum Transport Solver to Explore 2D Material Space for Transistor Operation
For decades, silicon has been the mainstay of the semiconductor industry. However, to preserve the electrostatic integrity of MOSFETs (metal oxide semiconductor field effect transistors), technology downscaling necessitates ... -
Infimal convolution approaches for image recovery
The quality of image captured by acquisition devices has increased drastically over the years largely due to a revolution in imaging sensor capability. But, image acquisition under low illumination continues to be a ... -
Conceptualization and Validation of Interoperability in Blockchain Enabled Interconnected Smart Microgrids
Power systems are undergoing rapid transitions to incorporate renewable sources of generation and to combat climate change. It is expected that the next stage of transitions will lead to a shift from large-scale, centralized ... -
Role of Sirtuin6 in the maintenance of cardiac lysosomal homeostasis
The response to cardiac stress can be divided into two phases- an initial adaptive compensatory phase followed by a maladaptive decompensatory phase. Protein homeostasis in cardiomyocytes has been observed to behave ... -
Adjoint-Based Aerodynamic Shape and Mesh Optimization with High-order Discontinuous Galerkin Methods
The aerodynamic shape of an aircraft plays a pivotal role in determining its overall performance. Aerodynamic Shape Optimization (ASO) involves systematically modifying the geometry to optimize the aerodynamic objective ... -
