On the spatial extent of extreme rainfall events over India during the summer monsoon
The spatial extent of extreme rainfall events directly affects the damages caused and impacts of such events. However, it has been less explored in the literature. This thesis examines extreme rainfall events of different ... -
Lower Bound Finite Element Limit Analysis for Solving Different Planar and Axisymmetric Stability Problems in Soil and Rock Media
The finite element limit analysis (FELA), which utilizes the concept of finite elements and an optimization procedure, is a very powerful technique to find an accurate solution of different stability problems in geomechanics. ... -
Simulation and Characterization of Streamflow Time Series
Streamflow can be partitioned into distinct time scales to better understand the underlying governing processes: fast flow, representing surface runoff controlled mainly by meteorological processes that operate over ... -
Microstructure and texture engineering strategies to enhance the corrosion resistance of tin based coatings
Coating corrosion-prone material with metal/alloy and passivated oxide layers is the primary protection method in the ever-evolving corrosion protection area. To improve the corrosion resistance of the coatings, the coating ... -
Supercritical CO2 Power Cycles and Turbomachinery Development for Renewable Energy and Waste Heat Recovery
Supercritical carbon dioxide (sCO2) power cycles have transitioned from the kilowatt level pilot facilities to the megawatt level demonstration plants. Theoretical studies and commercial benefits associated with sCO2, such ... -
Photocatalytic and Photoelectrocatalytic systems for water remediation and energy applications

Microstructure and Electrochemical Properties of Electrodeposited High Entropy Alloys Coatings
High entropy alloys (HEA) are composed of five or more alloying elements in a nearly equi-atomic ratio. HEAs exhibit high oxidation and corrosion resistance behaviour. In this work, HEA coatings were electrodeposited over ... -
Architecting and Developing Sensors for Environmental Monitoring
Pollution arising from inorganic and organic contaminants is a major environmental hazard that needs imperative attention. Anthropogenic and natural deposition of heavy metal ions constitute a significant component of this ... -
Study of solvent induced polymorphism and crystal nucleation from solution
Crystal polymorphism is the existence of different crystal structures for the same compound. Different polymorphs will have different physical properties, such as solubility and dissolution rate. The early stage of ... -
Permeability Modeling for Single Scale and Dual Scale Fabrics and its implementation to Fabrics Undergoing Shear
Composites have found applications, right from high-end aerospace structures to naval and land-based structures. These structures are realized by manufacturing processes like, autoclave and vacuum assisted resin transfer ... -
Intelligent Gaze Controlled Interface for Limited Mobility Environment
Eye movement-based Human Computer Interaction (HCI) has become a significant area of research in computer science. The gaze-based computing devices allow a computer to be controlled using only eye movements, which can be ... -
