Propagation characteristics in elastic waveguide with discrete nonlinearity
Wave propagation in elastic continuum is a subject of interest in many fields of engineering and has been explored for several decades from theoretical, computational and experimental perspective. In this context, a ... -
Propagation of a curved weak shock front
Waves are ubiquitous in the physical world. The study of general laws that govern their propagation is, therefore, important. In particular, nonlinear hyperbolic waves are frequently encountered, for some of which the ... -
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this emergence has been ... -
Prospects of Bioethanol from Estuarine Macroalgae
Burgeoning dependence on fossil fuels for transport and industrial sectors has been posing challenges such as depletion of fossil fuel reserves, enhanced greenhouse gas (GHG) footprint, and imminent changes in the climate, ... -
Pseudo-binary and Pseudo-ternary diffusion couple methods for understanding the growth of interdiffusion zone between bond coat and superalloys
Ni-based superalloys are widely used in jet engine applications. Bond coats are applied to these alloys for protection during service in a very harsh environment at high operating temperature. The addition of Pt to the ... -
Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures
(Indian Institute of Science, 2005-07-27)This thesis is devoted to the deposition of intermetallic thin films by laser ablation deposition (LAD) and their characterization. Pulsed laser ablation and subsequent deposition of the ablated vapours produces films under ... -
Quality-quantity trade off during antibody production and the design of optimal passive immunization protocols
Passive immunization has been used classically to rapidly clear antigen and reduce disease burden. Surprisingly, recent studies have found passive immunization to induce lasting improvements in the humoral response, ... -
Quantification of Air-Sea CO2 exchange from the Southern Ocean during last deglaciation
Glacial and interglacial cycles are natural, rhythmic patterns of global climate. These cycles are primarily driven by variations in solar forcing, commonly known as Milankovitch cycles. The solar forcing includes eccentricity ... -
Quantification of irrigation and crop water productivity using soil moisture dynamics
Estimating water budgets in agricultural fields is key to evaluating and improving water management. However, quantifying hydrological components remains a challenge, especially estimation of irrigation quantities and ... -
Quantification of Uncertainties in Urban Precipitation Extremes
(2018-05-25)Urbanisation alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. Quantification of uncertainties is important in hydrologic designs of ... -
Quantification of uncertainties in urban precipitation extremes
Urbanization alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. In general, quick runoff response to precipitation extremes due to short ... -
Quantitative Laser-Based Diagnostics and Modelling of Syngas-Air Counterflow Diffusion Flames
(2018-06-05)Syngas, a gaseous mixture of H2, CO and diluents such as N2, CO2, is a clean fuel generated via gasification of coal or biomass. Syngas produced via gasification typically has low calorific values due to very high dilution ... -
Quantum-Continuum Modeling and Simulations of Semiconductor Nanostructures
This thesis proposes a multi-physics model to couple the electrical, mechanical, thermal and quantum mechanical interactions in semiconductor and their heterostructures. Governing differential equations and constitutive ... -
Quasi-Static and Implicit-Dynamic Finite Element Solution of Large Deformation Elastic Adhesive Contacts Using a Volumetric Interaction Scheme
Adhesive forces, mediated by van der Waals’ and other interactions, dominate the contact response in the micron and sub-micron regimes. Understanding adhesion is especially important in biological systems (interaction of ... -
Radiative effects of aerosols over land and ocean
The last two centuries have witnessed tremendous growth on all fronts (especially industrial) compared to what had occurred in the past thousands of years. This growth brought along, in addition to the awareness of safety ... -
Radiative interactions in boundary layers
The flow of a compressible, viscous, heat-conducting, radiating gray gas parallel to a gray semi-infinite flat plate is considered. The radiation field is described by using the differential approximation. N, the ratio of ... -
Rate Enhancement Of The Catalytic Hydrogenation Of An Unsaturated Ketone By Ultrasonic Irradiation
(Indian Institute of Science, 2005-08-25)The aim of the work was to develop an understanding of the phenomenon of rate enhancement observed when a heterogeneous catalytic reaction system is irradiated by ultrasound. The system under investigation was the catalytic ... -
Rational approach to solid finite elements
The finite element method today has become a powerful tool in engineering analysis and design. The ease of application, reliability of solutions, and its ability to model complex geometries seem to be the main reasons for ...
