Assessing the potential of stable calcium isotope ratios for paleotemperature reconstruction from studies of laboratory-precipitated inorganic carbonates and modern corals, fish otoliths and foraminifera
Determining paleo-seawater composition and temperature is critical for reconstructing Earth’s surface conditions through time and has major implications for understanding the origin and evolution of life on Earth. ...
Energetics of monsoon variability over the last 22,000 years
The interpretation of proxies of paleo monsoons has been based primarily on changes in incident solar
radiation. The role of feedbacks has not been examined in depth. In this thesis, we have used a diagnostic
model of ...
Development of Seismic Design Spectra For Shallow and Deep Soil Sites Considering Region Specific Parameters
Earthquakes are among the deadliest in all the natural disasters and have affected
many people in the last few decades. The efforts to reduce or mitigate the impact of
earthquakes have become increasingly focused upon ...
Jet Injection into Supersonic Crossflow: Flowfield and Mixing studies
Supersonic air-breathing engines or scramjets are perhaps the most important technological
hurdles towards the development of hypersonic transportation vehicles for both easy
access to space and for missile related ...
Modelling Hydrology of Upper Cauvery Basin Considering Changes in Climate and Landuse/Landcover
In the recent times, changes are noted in hydrological processes (e.g., surface runoff, lateral flow, infiltration, return flow, evapotranspiration, soil moisture and streamflow) in different river basins of the world due ...
Experimental Investigation of Fuel Drop Impact on Unheated and Heated Solid
The modelling of spray-wall interaction encountered in engine combustors relies heavily on studies of single drop impact on heated solid surfaces. In the present thesis, the impact of a single fuel drop on a hot, smooth ...
TEM Characterization of Microstructural Evolution of GaN Grown by MOCVD on c-Sapphire
III-Nitrides (AlN, GaN, InN) find use in the high-power high frequency applications. Bulk GaN substrates are difficult to grow, therefore the GaN based structures must be grown on foreign substrates.
In this thesis, ...
Development of PCM coupled heat pipe for space application
Axially grooved aluminium-ammonia heat pipes are extensively used for the thermal control of satellites. Heat pipes efficiently transfer waste heat from the electronic packages, housed inside the satellite, to thermal ...
Shock Dynamics due to Downstream Pressure Perturbations: Idealization of Transonic Unstarted Cascade Flutter
Shock wave unsteadiness is an important phenomenon in high-speed aerodynamics. This
phenomenon is observed in many locations of high-speed vehicles, such as supersonic inlets,
ramjet engines, transonic airfoils, high-speed ...
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 ...
