New Dispersive Techniques for Quantum Field Theories
Quantum field theory has been remarkably successful in describing interactions of elementary particles, particularly through perturbative methods. However, many important regimes — including strong coupling and quantum ... -
Designing Functional Supramolecular Assemblies for Enzyme Activity Regulation
Enzymes are essential biocatalysts that perform chemical and biochemical reactions in living organisms. Dysregulation in enzyme activity is responsible for several metabolic disorders and lethal diseases such as Alzheimer’s ... -
Modeling, Analysis and Control of Switched Reluctance Generator
Switched reluctance machines (SRM) are permanent magnet-free and have a simple rotor with no current-carrying conductors. SRM can be operated as a generator and driven by renewable energy resources such as wind, solar-thermal, ... -
Class Incremental Learning Across Diverse Data Paradigms
Class Incremental Learning (CIL) is a fundamental machine learning paradigm that enables models to continuously learn new classes over time, while retaining previously acquired knowledge. Despite significant progress, ... -
ML based Intrusion Detection System for IEC 61850 MMS
Cyberattacks targeting operational technology (OT) systems, such as power grids, have evolved into highly sophisticated threats. In the last two decades state-sponsored adversaries have increasingly weaponized ... -
Analysis of Groundwater Systems Using Lumped and Distributed Hydrological Models: Applications in Indian Tropical Region
Groundwater is a critical resource for meeting agriculture, domestic, and industrial water demand, particularly in tropical regions of India. However, increasing groundwater extraction, erratic monsoonal rainfall, and ... -
Effect of Flow Regime on Performance of Rotating Gliding Arc Reactor: Experimental and Simulation Studies
Non-thermal plasma (NTP) technology offers a promising approach for pollutant abatement, gas conversion, and plasma-assisted combustion (PAC) by enabling reactions under atmospheric conditions, bypassing thermodynamic ... -
Heterogeneous host-pathogen interactions contribute to antibiotic tolerance in Mycobacterium tuberculosis
Eradication of Mycobacterium tuberculosis (Mtb) requires strategies targeting bacteria inside the host. Mtb exhibits heterogeneity in redox metabolism inside macrophages to evade killing by anti-TB drugs. If and how ... -
Nano-engineering in Ionic Liquid: From Fundamentals to Advanced Catalysis
Harnessing nanostructured materials of metals has led to the development of various synthetic methodologies. Although various strategies have been developed, challenges still remain obtaining desired shape, size, and ... -
Redox Active Antioxidant Nanozymes as Potential Antithrombotic and Antiviral Agents
Reactive oxygen species (ROS), such as superoxide (O2-) hydrogen peroxide (H2O2), and hydroxyl radicals (.OH), generated as a result of cellular metabolism, play a multitude of physiological roles. They play key roles in ... -
Structural Insights of Inter-domain Interactions in Multi-domain Proteins
Embargo up to August 11, 2026. Proteins are essential biomolecules whose diverse functions stem from their modular architecture built from independently folding units called domains. This thesis investigates the nature and ... -
Mathematical Modelling and Advanced Control Techniques for Irrigation Canal Management
Efficient water management in irrigation canal systems is vital for sustainable agriculture and environmental conservation. This thesis presents advanced control strategies to optimize water distribution and address the ... -
On Orbits and Border of Constant Read Circuits and Lower Bounds for Constant Depth Circuits
Two of the most common ways in which arithmetic circuits can be restricted is by requiring that they be constant read or constant depth. Constant depth circuits have received a lot of attention in the arithmetic circuit ... -
Some results on beta ensembles and on scaling limits of random graphs
This thesis is divided into two main parts, each of which can be studied independently of the other. The first part is devoted to the study of beta ensembles (β-ensembles). The main theme in β-ensembles, in this thesis, ... -
Machine-Learning-Based investigations in Complex Systems: Droplet Coalescence, Ising-type models, and Mathematical Models for Cardiac Tissue
The importance of artificial intelligence and data driven machine learning is growing exponentially in time as are its applications in investigations of complex phenomena in, e.g., climate-systems science, fluid flows, ... -
Bipartite pore-forming toxin YaxAB: understanding pore formation using live-cell imaging
Bacteria employ a variety of strategies to invade and colonise the host tissue, including the secretion of toxins to overcome the cellular barrier. Bacterial pore-forming toxins (PFTs) disrupt the lipid bilayer by forming ... -
Isolation of Arsenic and Sodium Hydroxide Recovery Using Nanofiltration for a Zero-waste Arsenic Remediation Scheme
Groundwater contamination by arsenic poses a significant global health concern, with even trace concentrations leading to severe health issues, including various cancers and cardiovascular diseases. Conventional arsenic ... -
Development of Analytical Solution Methodologies for a Class of Problems in Last Mile Delivery (LMD) of LPG Cylinders (LPG-C) in India
Last Mile Delivery (LMD) relates to all the logistics related activities carried out towards delivery of shipments to the end customers and is considered as the most expensive and time-consuming stage in the supply chain ... -
Exploring Scalar-Tensor Theories of Gravity in Light of Tensions and Anomalies in Standard Cosmology
The $\Lambda$CDM model, the standard model of cosmology, has been highly successful in describing a wide range of cosmological observations. However, in the era of precision cosmology, it faces increasing challenges in the ... -
Thermal one point functions in large $N$ vector models and holography
This thesis develops analytic methods to evaluate thermal one point functions in holography and a class of conformal field theories(CFT) described by large $N$ vector models. For planar charged black holes in $AdS_{d+1}$ ...
