Orbit Model Analysis And Dynamic Filter Compensation For Onboard Autonomy
(2009-03-04)Orbit of a spacecraft in three dimensional Inertial Reference Frame is in general represented by a standard set of six parameters like Keplerian Orbital Elements namely semimajor axis, eccentricity, inclination, ... -
Orbital Evolution And Super-Orbital Flux Variations In X-ray Binary Pulsars
(2010-08-23)X-ray binaries are binary stellar systems containing a compact object and a normal companion star which are gravitationally bound and rotate about a common center of mass. The compact object accretes matter from the companion ... -
Oriented molecules theoretical studies on mixed liquid crystals of opposite crystal
The thesis consists of two parts. Part I describes theoretical studies in mixed liquid crystals of opposite diamagnetic anisotropies. Part II deals with experimental NMR studies in single and mixed liquid crystals of ... -
Origin of Instability and Plausible Turbulence in Astrophysical Accretion Disks and Rayleigh-stable Flows
(2017-12-10)Accretion disks are ubiquitous in astrophysics. They are found in active galactic nuclei, around newly formed stars, around compact stellar objects, like black holes, neutron stars etc. When the ambient matter with ... -
Origin Of The Extragalactic Gamma-Ray Background
(2013-10-01)It is evident that the origin of EGRB is not well established. In this thesis I examine the unresolved discrete origin of EGRB. The contribution from normal galaxies, starburst galaxies and AGNs to the EGRB is examined. ... -
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 ...
