Experimental and Numerical Evaluation of Mechanical Response of Unsaturated Soils and Their Application to Embankments and Footings
Naturally, soils are rarely fully saturated, and climatic and environmental conditions frequently cause moisture content to change. Due to the varying climate changes and its effects on compacted engineering structures, ... -
Inkjet-printed high performance oxide electronics and its application at sensor interfaces
Over the last two decades, printing of oxide semiconductors has received special attention due to its advantages such as low processing temperature, even at room temperature; high electron mobility; good transparency due ... -
Thermoplastic epoxy designed using Vitrimer chemistries
Globally, 70 million tons of epoxy thermosets are manufactured at a perplexing rate which constitutes approximately a quarter of polymer generation by weight. A thermosetting polymer contains a permanent crosslinked network ... -
Effect of thermo-mechanical treatment on the evolution of microstructure and mechanical properties in a β and a β rich α+β titanium alloy
Near β and metastable β-titanium alloys are difficult to process due to narrow processing window. Lower processing temperature causes difficulty in recrystallization of these alloys especially in the two phase conditions, ... -
Uniaxial Fatigue Behavior of Freestanding Platinum-Aluminide (PtAl) Bond Coat
Pt-aluminide (PtAl) bond coat is used as a part of Thermal Barrier Coating (TBC) system on Ni-base superalloy components in advanced gas turbine aeroengines. The thickness of B2-NiAl intermetallic based diffused coating ... -
Model-based Evaluation of Multiple Solutions to Grid Integration Challenges of Large-scale Renewable Power
Worldwide renewable installations are growing exponentially in the electricity mix. In a renewable-rich electricity grid, the demand, as well as the generation, varies in different time scales. It is highly complicated to ... -
Aggregate and Disaggregate-level Models of Public Transit Ridership in Bengaluru, India
Ridership forecasting models are valuable tools for public transit agencies to assess and quantify the possible impacts of their operational strategies and service improvements on transit demand and revenue. Although ... -
Mesoscale Modelling of sheared lamellar mesophases
The lamellar phase or smectic lyotropic liquid crystalline medium, which is made up of alternating flat sheets of water and surfactant bilayers shearing past each other in an imposed flow. Surprisingly, In practical ... -
Exploring Hydrological Processes, Modeling Decisions, and Deep Learning for Improved Hydrologic Assessment
Hydrological modeling is complicated by the intricate challenges and uncertainties associated with understanding hydrological processes. This thesis aims at answering some of the key research questions related to ... -
Numerical Simulations of Deforming Capsules and Cells in a flow
Understanding the evolution of deforming capsules and cells in various flow configurations can assist in better diagnosis of diseases like Malaria and sickle cell anemia. Flow of deformable capsules is also useful in ... -
Investigation of multiscale biological phenomenon using kinetic modeling and molecular dynamics simulations
Biological systems inherently function at multiple spatial and temporal scales by integrating information across these scales. In this thesis, we are interested in investigating two classes of biological phenomena that ... -
Micromechanical understanding of the macroscopic features of dense granular materials
The prevalence of granular materials in nature (soil, beach sand, rubble pile asteroids) and in several industries (cement, food grains, pharmaceutical powders) has motivated extensive research towards understanding the ... -
Longitudinal Acceleration-based Variable Speed Bio-inspired Guidance Law
Most analyses of existing interceptor guidance laws assume the interceptor speed to be constant, which simplifies mathematical analysis and enhances predictability in interception characteristics. In reality, this is not ... -
Ecology of the terrestrial carbon cycle: Influence of climate and animals
The terrestrial carbon (C) cycle involves fluxes between multiple pools that determine ecosystem functions and regulate global climate. These fluxes and pools are influenced by changes in abiotic (temperature, precipitation ... -
Characterization and Control of Boundary Layer Transition Caused by Distributed Surface Roughness
Distributed roughness occurs over a variety of aerodynamic surfaces such as wind-/gas-turbine blades and aircraft wings in the form of dust, insect strikes, fouling or icing. The disturbances introduced by the roughness ... -
High-Throughput Bending Tests for Investigating Creep Behavior Affected by Structural and Microstructural Inhomogeneities
The bending of cantilevers is an alternate technique for the extraction of power-law creep parameters of materials. It has been shown earlier that in homogeneous systems showing tension-compression symmetry, digital image ... -
Damping of magnetic-Coriolis waves with imposed magnetic field orthogonal to the axis of rotation
Small-scale columnar structures (<10 km radius) in Earth's outer core result from inertial waves. In highly conducting fluid, magnetic field behaviour resembles stretched elastic strings and transmits disturbances as Alfvén ... -
Ground Displacements and Stresses around Single and Twin Tunnels using Analytical and Numerical Approaches
