Hydrodynamic and hydromagnetic instabilities leading to turbulence in astrophysical accretion disks and their connection to laboratory shear flows
Accretion disks are astrophysical objects formed around a denser object, mainly in the form of a disk. In an accretion disk, matter spirals in and falls onto the central object. To match the observations, the underlying ... -
Hydrodynamic stability of shear flows : Jet in crossflow, particle laden planar and swirling jets
Jet in crossflow is a flow scenario that involves momentum exchange of a round jet injected into a crossflow. This flow configuration has industrial importance because of its application in gas turbine combustors which ... -
Hydrodynamics Of An Oscillating Foil With A Long Flexible Trailing Edge
(2010-09-24)In nature, many swimming and flying creatures use the principle of oscillatory lift-based propulsion. Often the flapping element is flexible, totally or partially. The flow dynamics because of a flexible flap is thus of ... -
Hydrogen passivation and photoconductivity in Si/Si1-xGex and Si1-xGex/Ge modulation doped heterostructures
In conclusion, we have shown for the first time that the parallel conduction and other kinds of parasitic contributions to the channel mobility can be reduced effectively by hydrogen passivation, and an enhancement in the ... -
Hydrologic Impacts of Climate Change : Detection and Attribution
Detecting, quantifying, and modelling the effects of human-induced climate change in regional hydrology is important for studying the impacts of such changes on the water resources systems as well as for reliable future ... -
Hydrologic Impacts Of Climate Change : Uncertainty Modeling
(2009-07-02)General Circulation Models (GCMs) are tools designed to simulate time series of climate variables globally, accounting for effects of greenhouse gases in the atmosphere. They attempt to represent the physical processes in ... -
Hydrologic Impacts Of Clmate Change : Quantification Of Uncertainties
(2011-02-10)General Circulation Models (GCMs), which are mathematical models based on principles of fluid dynamics, thermodynamics and radiative transfer, are the most reliable tools available for projecting climate change. However, ... -
Hydrologic Inference: A Complex Systems Approach
The aim of this thesis is to understand linkages between hydrologic processes and patterns from the perspective of a complex system. In hydrologic systems, there exist interactions of hydrologic components among themselves ... -
Hydrologic Response of Upper Ganga Basin to Changing Land Use and Climate
(2018-04-17)Numerous studies indicate that the hydrology of a river basin is influenced by Land Use Land Cover (LULC) and climate. LULC affects the quality and quantity of water resources through its influence on Evapotranspiration ... -
Hydromagnetic surface waves
The ASW propagates as a dispersive wave along the boundaries of a bounded plasma column. At the interface of a plasma slab surrounded by two identical plasma media, two modes-symmetric and asymmetric-propagate with a phase ... -
Hydrophobicity and Composition-Dependent Anomalies in Aqueous Binary Mixtures, along with some Contribution to Diffusion on Rugged Energy Landscape
(2018-01-28)I started writing this thesis not only to obtain a doctoral degree, but also to compile in a particular way all the work that I have done during this time. The articles published during these years can only give a short ... -
Hydrothermal Synthesis of Carbon Nanoparticles for Various Applications
(2018-02-20)Carbon nanoparticles (CNPs) have drawn great attention in the last few years owing to their unique properties such as excellent water solubility, chemical stability, inertness, low toxicity, good bio-compatibility, and ... -
Hyperbranched Polyacetals and Polydithioacetals
(2018-04-23)Dendrimers are a class of perfectly branched symmetric monodisperse macromolecules, which are synthesized using a stepwise procedure. Due to their highly symmetric structure, they possess a definite core, discrete generations ... -
Hypercube variant interconnection networks
The attractive properties of the hypercube have made it a popular interconnection network topology for the design of multicomputers. Researchers have been modifying the hypercube topology in subtle ways to improve upon a ... -
Hyperfine Structure-Measurement in Alkali-metal Atoms and Ytterbium Atom
(2018-02-15)Atomic precision measurements provide a strong testing ground for new theoretical ideas and fundamental laws of physics. Measurement of the Lamb shift in the hydrogen atom is one of the best examples towards this -it ... -
Hypergraph Network Models: Learning, Prediction, and Representation in the Presence of Higher-Order Relations
The very thought about “relating” objects makes us assume the relation would be “pairwise”, and not of a “higher-order” — involving possibly more than two of them at a time. Yet in reality, higher-order relations do exist ... -

Hyperplane Partitioning : An Approach To Global Data Partitioning For Distributed Memory Machines
(Indian Institute of Science, 2005-12-07)Automatic Global Data Partitioning for Distributed Memory Machines (DMMs) is a difficult problem. Distributed memory machines are scalable, but since the memory is distributed across processors, the scheme of placement ... -
Hyperspectral and Spectropolarimetric Instrumentation for the Solar Atmosphere
The Sun is the closest star whose surface can be resolved to great a detail. Understanding the working of Sun helps in understanding a large fraction of stellar system as it falls under the spectral class G2V which is ... -
Hyperspectral Image Fusion with Implicit Regularization
Hyperspectral (HS) satellite images contain rich spectral information but generally suffer from low spatial resolution. In contrast, multispectral (MS) images offer higher spatial resolution but only a limited number of ...
