Deciphering the evolutionary ecology of snake venoms and its impact on snakebite therapy in India
Venom, being an adaptive trait, has propelled the expansion of snake lineages across diverse habitats, such as the biogeographically distinct Indian landscapes. Natural selection optimises the potency, composition and ... -
Investigation into flux-coupled electromechanical devices
Cavity optomechanical systems involve modulation of the resonance frequency of an optical cavity by the motion of a mechanical resonator. These systems are used to control and manipulate mechanical motion down to the quantum ... -
On two complex Hessian equations and convergence of corresponding flows
This thesis consists of three parts. Two important complex Hessian equations are studied on certain compact K\"ahler manifolds from different perspectives. The first one is the {\em J-equation} introduced independently by ... -
Investigating the role of moisture in vernacular and conventional building typologies for occupant comfort and health
Moisture is omnipresent and critical to sustain life on the planet. In buildings, it is observed in the form of indoor moisture, dampness on walls, seepages, etc. As building occupants, humans perceive moisture in the air ... -
Efficient and Effective Algorithms for Improving the Robustness of Deep Neural Networks
Deep Neural Networks achieve near-human performance on several benchmark datasets, yet they are not as robust as humans. Their success relies on the proximity of test samples to the distribution of training data, resulting ... -
Modeling physiological transport at scales: connecting cells to organs
The physiological system is a complex network in which each organ forms a subsystem, and the functional networks in different subsystems communicate to maintain the body’s overall homeostasis. The ability to simultaneously ... -
Tight Frames, Non-convex Regularizers, and Quantized Neural Networks for Solving Linear Inverse Problems
The recovery of a signal/image from compressed measurements involves formulating an optimization problem and solving it using an efficient algorithm. The optimization objective involves data fidelity, which is responsible ... -
Extraction of Bond Coat Mechanical Properties using High- Temperature Digital Image Correlation
Gas turbine engines used in aircraft or power generation widely use nickel-based superalloys in their hot sections such as combustion chambers, turbine blades, etc. These components in the hot section use thermal barrier ... -
A model-based investigation of the long-term climate and carbon cycle consequences of fossil fuel emissions, land use changes and negative emissions
In this thesis, we investigate the effects of anthropogenic perturbations such as fossil fuel emissions, deforestation, afforestation and negative emissions on the long-term climate and carbon cycle using simulations from ... -
A Neural Network Approach to Modelling Hawkes Processes for Financial Applications
In 1971, Alan Hawkes introduced a set of stochastic point processes characterized by the unique feature that the incidence of an event heightened the likelihood of subsequent events, leading to the clustering of events. ... -
A scalable asynchronous discontinuous Galerkin method for massively parallel flow simulations
Accurate simulations of turbulent flows are crucial for understanding numerous complex phenomena in engineered systems and natural processes. Notably, under realistic conditions with high Reynolds numbers and complex ... -
Syntheses and structural characterization of Cu-TPY ternary complexes with nucleotides and its constituents
Syntheses and Structural Investigations of Cu(II) Ternary Complexes of Nucleotide and its Constituents with Terpyridine. The major interest in the field of metal-nucleic acid chemistry arises due to the crucial role of ... -
Electrophysiological studies investigating drug effects on hHCN1 channels and Unravelling pore dynamics in Pannexin channels
Hyperpolarization-activated cyclic nucleotide-gated (HCN) ion channel stands out for its unique characteristics, including sensitivity to transmembrane voltage and cyclic nucleotides, as well as its non-selective passage ... -
Dissipative Mechanisms in Organic Light-emitting Diodes: Role of Intramolecular Charge Transfer and Delayed Fluorescence
Organic light-emitting diodes (OLEDs) are emerging to replace conventional lighting technology due to their flexible device structures, multicolour emission, and ease of fabrication. However, one of the key challenges in ... -
Self-sustained oscillations in high-speed cylinder wake flows
Flow in the wake generated by a solid body presents an important class of problems in fluid dynamics, with wide ranging scientific implications and engineering applications. The present work investigates the structure and ... -
Multifunctional hydrogels with injectable, self-healing, and shape-morphing capabilities for biomedical applications
