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 $AdS_{d+1}$ ... -
Enhancing THC/NOX removal efficiency in diesel exhaust through catalyzing industrial wastes in the presence of electric discharge plasma
The consistent rise in air quality index in various cities has risen a worldwide concern toward the critical situation of air pollution and climate change. Despite the implementation of stringent regulations, the usage of ... -
Land-Climate Nexus: Unravelling Compound Extremes From Multivariate Analysis To Transformer Networks
The interplay between land use and extreme hydroclimatic events is a crucial aspect of Earth system science, influencing water resources, ecosystem stability, and disaster risk management. Extreme hydrologic events often ... -
A Descriptive Hierarchical Approach to Analyse Activities Through Causal Mechanistic View
Activities of Daily Living (ADLs) are essential routines that support individuals’ independence and well-being. For people with upper limb impairments, limitations in hand and arm function can make performing ADLs ... -
Navigation of Autonomous Vehicles using Event Cameras and Modified RRT Methods
Autonomous vehicles, such as unmanned aerial vehicles (UAVs) and autonomous mobile robots (AMRs), are at the forefront of technological innovation and are widely used across various applications. As these vehicles become ... -
Investigation of sea level anomalies along the Indian coastline using tide gauge data: a physics-guided machine learning approach
The Indian coastline falls within low-elevation coastal zones that are densely populated. Recent observations indicate, with high confidence, that the rate of sea level rise in the In- dian Ocean has been accelerating ... -
Particle-laden Rayleigh-Benard convection
Particle-laden flows are ubiquitous in nature and industries. For example, water droplets in clouds, fine dust particles in strong winds leading to dusty storms, dunes, ejection of solid particles and ash during volcanic ... -
Exploring the atomic-level solute-defect interactions for designing high-performance disordered Ni-Co base alloys and ordered Ni base superalloys
For structural applications, a major section of high-strength alloys, such as steels, superalloys, etc., has a base element of iron, nickel, cobalt, titanium, aluminium or their combinations. Such materials enable ... -
Tuning Properties of Heterogeneous Catalysts using First Principles and Machine Learning
The surface-to-volume ratio plays a crucial role in determining the catalytic performance of heterogeneous catalysts by influencing surface energy, reactivity, and stability. This thesis systematically explores how tuning ... -
One-domain simulation of fluid flow and heat transfer in the conjugate porous-clear media
In this thesis, based on generalized porous flow model, we present a one-domain framework for the simulation of incompressible flow in superposed clear and porous media. The continuous change in the characteristics of the ... -
Positivity properties of the deformed Hermitian-Yang--Mills and related equations
In the first part of the talk, we briefly introduce the deformed Hermitian-Yang-Mills (dHYM) equation and discuss a result regarding the solvability of the twisted dHYM equation on compact Kähler three-folds with slightly ... -
Investigating Magnetic Transitions and the Quantum Spin Liquid State in Complex Oxides
Magnetic properties emerge from the interplay of spin, crystal structures, and external factors such as temperature, magnetic fields, and pressure, resulting in a diverse range of magnetic phenomena with potential applications ... -
Sustainable solutions for municipal solid waste and leachate treatment: A circular economy approach
India’s waste management system, largely reliant on landfilling and open dumping, is inadequate for handling rising volumes of unsegregated muncipal solid waste (MSW), causing environmental and public health risks. Addressing ... -
Streaming Codes for Low-Latency Communication over Various Sliding-Window Channel Models
Streaming codes are packet-level codes that recover dropped (i.e., erased) packets within a decoding-delay deadline. A common model for packet erasures over a network is the Markov, two-state Gilbert-Elliott (GE) channel ... -
Remediation of Heavy Metal Contaminated Soil and Sediment And its Effective Reuse in Construction
This research explores approaches to mitigate the environmental impact of heavy metal contamination in soil and dredged sediment. It focuses on three main areas: chemical remediation through nano zero-valent iron (nZVI), ... -
Non-linear Hall Effect in Two- and Three-dimensional Materials
Underpinned by the concept of Berry curvature in band theory, the family of classical and quantized Hall effects are conventionally observed in the linear response regime. A measurable Hall response requires the time-reversal ... -
Behaviour Modelling of Non-Cooperative Space Objects and Strategies for Decision Support in Space Situational Awareness
Space Situational Awareness [SSA] is defined as the comprehensive knowledge of Resident Space Objects [RSO] which may include satellites, rocket bodies, debris etc. and the ability to understand their behaviour. SSA solutions ... -
