An Integrated Choice and Latent Variable Framework to Incorporate the Influence of Travel Time Variability on Truck Route Choice
Route choice models (or path choice models) are useful for quantifying travellers’ preferences for or sensitivity to route attributes, predicting network-level traffic flows, examining the influence of information provided ...
Experimental studies on Soot and Particulate reduction in Heavy Fuel Oil Combustion
Heavy fuel oil (HFO) is extensively used in industrial burners and marine engines. HFO droplet combustion gives rise to carbon particulates generated by pyrolysis, which are called cenospheres. There is a current hypothesis ...
Turbulence-Premixed Flame Interactions
The interaction between premixed flames and turbulence is an inherently non-linear phenomenon. Understanding such interactions has profound practical implications towards the development of better combustion devices and ...
Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract
Fatigue phenomenon is a gradual, permanent, micro structural change that takes place
in a material due to the application of repeated loading. In the case of quasi-brittle
materials like graphite and concrete, ...
Experimental Studies on Methanol Sprays for IC Engine Applications
In this work, studies have been conducted on sprays of methanol and its emulsions with diesel towards assessing the potential of methanol as an alternative fuel for IC engines. Methanol can be used in compression ignition ...
Trends and Variability in Terrestrial Carbon Fluxes and Stocks over India in the 20th and 21st centuries: A Multi-model Based Assessment
Terrestrial ecosystems play an important role in the global carbon cycle by naturally taking up carbon from the atmosphere through photosynthesis and storing this carbon as biomass and soil carbon. There exists a strong, ...
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ...
Advanced Guidance Laws for Field-of-View and Impact Angle Constrained Engagements
This thesis deals with the development of guidance laws for interceptors with seeker field-of-view
(FOV) and impact angle constraints. Two classes of guidance problems, namely, field-of-
view and impact angle constrained ...
Structural dynamic testing for seismic response simulation and time variant reliability estimation
The research work reported in this thesis addresses a few problems which arise in the context of experimental dynamic testing of engineering structures under earthquake loads. Firstly, we consider the problem of characterizing ...
Investigations on Impinging Shock Wave and Boundary Layer Interactions in Hypersonic Flow
Shock boundary layer interactions (SBLIs) rank among the most fundamental problems in high-speed aerodynamics and are a primary concern in hypersonic flows. Shocks at hypersonic speeds are typically strong enough to separate ...
