Phase Modulated Selective NMR Methods for resolving overlapping spin systems and rapid data acquisition : Application in metabolomics
research work is focused on the development of new fast solution NMR methods for resolving overlapping spin systems and their application to NMR based metabolomics. In this work two new solution NMR pulse sequences are ... -
Phase Retrieval and Hilbert Integral Equations – Beyond Minimum-Phase
(2018-07-18)The Fourier transform (spectrum) of a signal is a complex function and is characterized by the magnitude and phase spectra. Phase retrieval is the reconstruction of the phase spectrum from the measurements of the magnitude ... -
Phase Sensitive Estimation Of Fluorescence Lifetime For Fiber Optic Biosensors
(Indian Institute of Science, 2005-10-04)Fluorescence lifetime determination and allied studies find application in spectroscopy in general and fiber optic biosensors in particular. Instruments and sensors cited in literature however use open loop, intensity based ... -
Phase Transformation Behavior Of Embedded Bimetallic Nanoscaled Alloy Particles In Immiscible Matrices
(2017-02-16)The aim of the present thesis is to understand the phase transformation behavior of embedded alloy nanoparticles embedded in immiscible matrices. Embedded alloy inclusions have been dispersed in immiscible matrix via rapid ... -

Phase Transitions And Magnetic Order In Multiferroic And Ferromagnetic Rare Earth Manganites
(2011-03-29)Recent findings of multiferroicity and magnetoelectric effects in rare earth manganites have fuelled research in this class of materials. These multiferroics can be structurally divided into two classes – orthorhombic and ... -
Phase Transitions And Relaxation Processes In Water And Glycerol-Water Binary Liquid Mixtures : Spin Probe ESR Sudies
(2010-11-18)A liquid Cooled below its normal freezing temperature is known as a supercooled liquid. On further cooling, supercooled liquids crystallize to thermodynamically stable, ordered structures. Alternatively, if the cooling ... -
Phase-field modeling of equilibrium shapes of precipitate and growth instabilities in the presence of coherency stresses
Precipitation-hardened alloys are one of the most technologically significant materials that are used for structural applications, where an important mode of strengthening is due to the impediment to the movement of ... -
Phases, Transitions, Patterns, And Excitations In Generalized Bose-Hubbard Models
(2016-09-12)This thesis covers most of my work in the field of ultracold atoms loaded in optical lattices. This thesis can be divided into five different parts. In Chapter 1, after a brief introduction to the field of optical lattices ... -
Phenomenological Explorations in Dark Matter
The previous decade has seen an explosive increase in explorations into the nature of dark matter (DM) encompassing astrophysical, particle and cosmological probes. We face today a large body of gravitational evidences ... -
A phenomenological one-dimensional model for elastic ribbons
Ribbons exhibit fascinating buckling-dominated behavior under mechanical loading because of a unique combination of geometric dimensions. The recent interest in examining engineering applications of ribbon-like structures ... -
