Packaging and Functionalization of Fiber Bragg Grating Sensors for Various Sensing Applications.
In our world, numerous sensors are found everywhere, making our lives simpler and more comfortable. Among these sensors, optical sensors have undergone expeditious development, providing good performance. In particular, ... -
Panchromatic study of star clusters: binaries, blue lurkers, blue stragglers and membership
Binary systems can evolve into immensely different exotic systems such as blue straggle stars (BSSs), yellow straggler stars, cataclysmic variables, type Ia supernovae depending on their initial mass, the orbital ... -
Particles and Fields in Active Turbulence
I have extended various facets of modern turbulence theory to hydrodynamic models of dense bacterial suspensions, which show turbule= nt-like patterns, dubbed active turbulence. By using direct numerical simulations (DNSs) ... -
Particles and Fields in Partial-differential-equation Models for fluid and Superfluid Turbulence
We have shown that uniformly rotating vortex-containing gravitationally-bound solutions of the GPPE can be generated by starting the evolution from initial data obtained by integrating to convergence the (imaginary-time) ... -
Particles and Fields in Superfluid Turbulence : Numerical and Theoretical Studies
(2017-12-16)In this thesis we study a variety of problems in superfluid turbulence, princi-pally in two dimensions. A summary of the main results of our studies is given below; we indicate the Chapters in which we present these. In ... -
Performance Characterization Of A Cylindrical Ion Trap Mass Spectrometer
(2011-01-31)The cylindrical ion trap (CIT) is made up of two planar endcap electrodes and a cylindrical ring electrode. The investigation of simpler geometries like CIT has been started off in recent years with a view towards ... -
Peristaltic Flows With Some Applications
(2007-12-29)Peristalsis is a mechanism of pumping fluids in ducts when a progressive wave of area contraction or expansion propagates along the length of a distensible tube containing fluid. It induces in general propulsive and mixing ... -

Phase Behaviour & Dynamics Of An Agitated Monolayer Of Granular Rods
(2010-10-05)In this thesis we have explored the no equilibrium phase behavior and dynamics of an agitated monolayer of macroscopic rod-like particles. The main objective of this thesis was to highlight the ways in which even the ... -
Phase separation and dynamics of concentrated colloids : Diffusing wave spectroscopy and brownian dynamics simulations
The purpose of this chapter is to summarize the principal results and conclusions reported in this thesis and also to point out the scope of further work. The focus of this thesis is on static and dynamic aspects of the ... -
Phase transition at critically, poisson convergence of isolated vertices and connectivity in random connection models
This work has two parts. The first part contains the study of phase transition and percolation at criticality for three random graph models on the plane, viz., the homogeneous and inhomogeneous enhanced random connection ... -
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 ... -
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 ... -
Phasons,topological defects and dynamics in incommensurate matter
In this thesis, we derive some physical consequences of the existence of a phason mode in incommensurate materials. We consider two main examples of such materials-quasicrystals and the incommensurate twist grain boundary ... -
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 ...
