Development of data processing techniques for laser doppler velocimeter based flow measurements
Several schemes are available for conditional sampling of data on the velocity of a flowing fluid obtained in analogue form. These schemes are usually applied directly to the analogue data or to the digital data obtained ... -
Developments In Quantum Information Processing By Nuclear Magnetic Resonance
(2011-08-02)Residual dipolar couplings can be used to increase the number of qubits for quantum information processing. We have used molecules containing 3, 5 and 8 spins oriented in a liquid crystal matrix, and exploited the residual ... -
Developments in two dimensional NMR spectroscopy of multiple quantum coherences of couples spins in liquids
The pathway description provides a straightforward method of computing flip-angle dependence of various multiple quantum coherences in the 2D MQ and the 2D COSY spectroscopy. Using this flip-angle dependence it is possible ... -
Dielectric property studies on Poly vinylidene fluoride composites with Graphene Oxide and functionalized Carbon nanotube fillers
Graphene Oxide (GO) and functionalized Carbon nanotubes (FCNT) are promising materials in the field of polymer composites due to their ability to disperse nicely in the polymer matrix. The functional groups present in these ... -
Dielectric, AC Conductivity, and EMI Shielding studies of PEDOT-PSS Nanocomposites with Carbon based Fillers
Polymer nanocomposites (PNCs) have emerged as a significant material for addressing two critical contemporary challenges: the escalating global energy demand and the pervasive electromagnetic interference (EMI) issues. The ... -
Dielectric, Mechanical, Magnetic and Electromagnetic Shielding properties of Carbon nanomaterial embedded Polydimethylsiloxane composites
Composites are the advanced engineering materials invented by men with exceptional properties over traditional materials. These attractive and delightful materials are the result of developments in the area of engineering ... -
Direct Measurement of Itinerant Magnetism & Interface States in Semiconductors using Time-varying Magnetic Fields
(2017-11-28)Magnetism in a solid | dia, para, ferro, or of other forms | originates majorly from its electrons; one could, infact, ignore the nuclear contribution. There are two types of electrons in a solid: bound, and free (also ... -
Direct Numerical Simulations of Fluid Turbulence : (A) Statistical Properties of Tracer And Inertial Particles (B) Cauchy-Lagrange Studies of The Three Dimensional Euler Equation
(2017-11-09)The studies of particles advected by tubulent flows is an active area of research across many streams of sciences and engineering, which include astrophysics, fluid mechanics, statistical physics, nonlinear dynamics, and ... -
Dissipative dynamics of classical and quantum systems
The organization is as follows. In Chapter II we introduce specific systems of interest, such as RBCs, microemulsions, tethered surfaces, and monolayer films of smectic-A and smectic-B systems. In Chapter III we calculate ... -
Driven Granular and Soft-matter : Fluctuation Relations, Flocking and Oscillatory Sedimentation
(2018-06-11)Active matter refers to systems driven out of thermal equilibrium by the uptake and dissipation of energy directly at the level of the individual constituents, which then undergo systematic movement in a direction decided ... -
Dynamical Imprint of Dark Matter Halo and Interstellar Gas on Spiral Structure in Disk Galaxies
(2018-08-29)The topic of this thesis deals with the spiral structure in disk galaxies with a specific aim of probing the influence of the dark matter halo and the interstellar gas on the origin and longevity of the spiral arms in ... -
Dynamics and Organization of Passive and Magnetically Driven Colloids Under Optical Confinement
The physics of confined systems of interacting particles has been a subject of active research for more than a century. Such systems are ubiquitous in nature - examples include petroleum in porous rocks, cytoplasm in ... -
