Development of Handheld Impedance Spectroscopy Instrument Suitable for Biological Tissue Characterization
(2017-11-27)Impedance spectroscopy (IS) is a powerful and sophisticated tool to characterize intrinsic electrical properties of any materials and its interface, measuring the electric and transport properties of the materials, ... -
Development Of Instrumentation For Electrical Switching Studies And Investigations On Switching And Thermal Behavior Of Certain Glassy Chalcogenides
(2010-07-08)The absence of long-range order in glassy chalcogenides provides the convenience of changing the elemental ratios and hence the properties over a wide range. The interesting properties exhibited by chalcogenide glasses ... -
Development Of NMR Methods For Metabolomics And Protein Resonance Assignments
(2017-05-25)Nuclear Magnetic Resonance (NMR) spectroscopy is a quantitative, non-invasive and non-destructive technique useful in biological studies. By manipulating the magnetization of nuclei with non-zero spin, NMR gives insights ... -

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 ... -
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, 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 ... -
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 ... -
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 ... -
Duality for Spaces of Holomorphic Functions into a Locally Convex Topological Vector Space
Consider an open subset O of the complex plane and a function f : O ÝÑ C. We understand the concept of holomorphicity of a complex-valued function. Suppose a function f defined on O takes values in a locally convex ... -
Dynamic Flow Rules in Continuum Visco-plasticity and Damage Models for Poly-crystalline Solids
Modelling highly non-linear, strongly temperature- and rate-dependent visco-plastic behaviour of poly-crystalline solids (e.g., metals and metallic alloys) is one of the most challenging topics of contemporary research ...
