Development Of Point-Contact Surface Acoustic Wave Based Sensor System
(Indian Institute of Science, 2007-05-16)Surface Acoustic Waves (SAW) fall under a special category of elastic waves that need a material medium to propagate. The energy of these waves is confined to a limited depth below the surface over which they propagate, ... -
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 ... -
Diamagnetically levitated nano positioners with large-range and multiple degrees of freedom
Precision positioning stages are indispensable in many branches of science and engineering, where they are employed for imaging, manipulation, fabrication, and material characterization. Compact, multi-degree-of-freedom ... -
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 ... -
A Digital Auto Correlation Spectrometer For Solar Burst Obsevations At Decameter Wavelengths
(Indian Institute of Science, 2006-02-27)This thesis reports the design, construction, and the initial results obtained from a digital spectrograph for observations of radio burst emission from the Sun. One of the distinct advantages of radio spectral studies of ... -
Dilation Theory of Contractions and Nevanlinna-Pick Interpolation Problem
In this article, we give two different proofs of the existence of the minimal isometric dilation of a single contraction. Then using the existence of a unitary dilation of a contraction, we prove the `von Neumann's ... -
Dilations, Functoinal Model And A Complete Unitary Invariant Of A r-contraction.
(2013-08-02)A pair of commuting bounded operators (S, P) for which the set r = {(z 1 +z 2,z 1z 2) : |z 1| ≤1, |z 2| ≤1} C2 is a spectral set, is called a r-contraction in the literature. For a contraction P and a bounded commutant ... -
Dipole Cosmology: Revisiting Our Universe with a Flow
In this thesis, we explore an ansatz alternative to the FLRW classes of spacetimes for our Universe, in light of observations that exhibit anisotropies at late times. Despite the existence of these anisotropies beyond ... -
Direct and Indirect Search for New Physics at Colliders
The Standard Model (SM) of particle physics has been remarkably successful to describe strong, weak and electromagnetic forces of nature, as it has agreed with most of the experiments till date. However, there are still ... -
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 ...
