Studies of Static and Dynamic Multiscaling in Turbulence
(Indian Institute of Science, 2005-06-17)
The physics of turbulence is the study of the chaotic and irregular behaviour in driven fluids. It is ubiquitous in cosmic, terrestrial and laboratory environments. To describe the properties of a simple incompressible ...
NMR Investigations Of Oriented Systems : Novel Techniques And Applications
(2011-02-22)
This thesis presents results of novel methodologies applied to oriented systems. Both pure liquid crystalline materials as well as molecules oriented in liquid crystalline matrices have been studied. In particular this ...
Synthesis, Optical And Photoelectrical Investigations On PbS nano-,micro-structures
(2010-10-21)
The thesis describes the synthesis of PbS nano-, micro-structures by colloidal and hydrothermal techniques. Size and morphology dependent luminescence studies were carried out in detail. Application oriented studies like ...
Generalizations Of The Quantum Search Algorithm
(2010-12-03)
Quantum computation has attracted a great deal of attention from the scientific community in recent years. By using the quantum mechanical phenomena of superposition and entanglement, a quantum computer can solve certain ...
Understanding the Behavior of the Sun's Large Scale Magnetic Field and Its Relation with the Meridional Flow
(2018-07-05)
Our Sun is a variable star. The magnetic fields in the Sun play an important role for the existence of a wide variety of phenomena on the Sun. Among those, sunspots are the slowly evolving features of the Sun but solar ...
Understanding DNA-Based Nanostructures using Molecular Simulation
(2018-05-14)
Deoxyribonucleic acid (DNA) is arguably the most studied and most important biological molecule. Recently, it has also been established as a potential candidate for nanoconstruction. Self-assembly of DNA molecules has ...
Establishing Super- and Sub-Chandrasekar Limiting Mass White Dwarfs to Explain Peculiar Type La Supernovae
(2018-06-23)
A white dwarf is most likely the end stage of a low mass star like our Sun, which results when the parent star consumes all the hydrogen in its core, thus bringing fusion to a halt. It is a dense and compact object, where ...
Numerical Studies Of Slow Dynamics And Glass Transition In Model Liquids
(2009-12-16)
An increase in the co-operativity in the motion of particles and a growth of a suitably defined dynamical correlation length seem to be generic features exhibited by all liquids upon supercooling. These features have been ...
Growth, Structural And Physical Properties Of Certain Antimony Based III-V Diluted Magnetic Semiconductors
(2010-07-20)
Semiconductor devices are the building blocks of electronics and communication technology in the modern world. The charge, mass and spin of charge carriers in the semiconductor devices lay the foundations of the technology ...
Electrical And Magnetic Properties Of Polyvinylchloride - Amorphous Carbon / Iron Carbide Nanoparticle Comosites
(2009-05-18)
The UV-Visible spectra of a-C composites and nano composites have provided a very useful information about the electronic states and band structure. The UV-Visible spectra of a-C as well as nanoparticle are qualitatively ...
