Dynamics of Single Shallow Arches and Statics of Connected Shallow Arches and their Applications
The methods developed in this thesis enable computationally efficient dynamic analysis of shallow arches. They also facilitate insightful design of arches for different applications. The first design study considers ... -
Role of buoyancy in driving upper ocean mixing across timescales
This thesis explores the response of the upper ocean to surface buoyancy fluxes on different timescales using theory, numerical simulations and observation-based datasets. First, we investigate the role of evaporation in ... -
Development of Generalizable Spiking Neural Network-Based Learning Frameworks For Solving Perimeter Defense Problem
Spiking Neural Networks (SNNs) are third-generation neural networks that can process information in a more biologically realistic way compared to other neural networks such as sigmoidal networks. They process the information ... -
Development of a novel LPG/PNG domestic burner for high efficiency and low emissions
Domestic cooking is one of the basic human needs, and cookstoves based on fuel combustion are widely used. LPG (Liquified Petroleum Gas) is the most common cooking fuel, followed by PNG (Piped Natural Gas), which has an ... -
Digitalisation of the Quality Management System in the Medical Device Industry for Certification
The Indian medical device manufacturing sector is rapidly growing yet faces persistent challenges related to regulatory compliance, limited access to advanced technologies, and economic constraints. These issues are ... -
A higher order finite volume discretization based on Staggered Update Procedure (SUP)
The unstructured data-based finite volume solvers are widely adopted in industrial computations owing to their robustness and flexibility in handling complex geometries. Most of these solvers use linear reconstruction ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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), ... -
Behaviour Modelling of Non-Cooperative Space Objects and Strategies for Decision Support in Space Situational Awareness
