Vector Bundles Over Hypersurfaces Of Projective Varieties
(2014-06-02)In this thesis we study some questions related to vector bundles over hypersurfaces. More precisely, for hypersurfaces of dimension ≥ 2, we study the extension problem of vector bundles. We find some cohomological conditions ... -
Vertical Structure Of Disk Galaxies And Their Dark Matter Halos
(2015-01-02)The topic of this thesis is the study of the vertical structure of the disk galaxies and their dark matter halos through theoretical modeling and numerical calculations. The basic theoretical model of the galactic disk ... -
Vertically aligned carbon nanostructures using ECR plasma and their applications
Vertically aligned carbon nanostructures are a type of carbon nanomaterial in which nanostructures are aligned lengthwise perpendicular to the plane of the substrate. In this thesis work, two vertically aligned carbon ... -
Vibrational Spectroscopic and Dielectric Studies of some Ferroic Crystals
The polarized Raman spectra of LCS are studied in the room temperature orthorhombic and the low temperature monoclinic phases. The observed Raman lines are assigned in the C(aa)B setting. The polarized spectra agree well ... -
Warped Galaxies : Recovery Of Pattern Speed, Velocity Field And The Warp Equation
(2015-08-04)Pattern speed is an important parameter of the density wave theory for spiral galaxies. In this thesis we have determined the pattern speed for warped galaxies (flat galaxies being a special case of this generalization) ... -
Water Quality Monitoring Using Fibre Bragg Grating Sensors
The quality of water is an important factor in human health, ecosystem balance, and sustainable development. The growing presence of contaminants such as heavy metals and bio-pathogens in water bodies poses significant ... -
Wearable Sensors using Solution Processed 2D Materials
Wearable sensors, as the name implies, are devices that can be donned onto the body in order to continuously detect, monitor and analyze various signals generated by the subject and the immediate surroundings. Applications ... -
Weighted Norm Inequalities for Weyl Multipliers and Hermite Pseudo-Multipliers
(2018-05-30)In this thesis we deal with two problems in harmonic analysis. In the first problem we discuss weighted norm inequalities for Weyl multipliers satisfying Mauceri’s condition. As an application, we prove certain multiplier ... -
Weights of highest weight modules over Kac-Moody algebras
In this dissertation, broadly, we treat the weight-sets of arbitrary highest weight modules (uniformly) over all general complex Kac-Moody Lie algebras $\mathfrak{g}$, achieving the below. We obtain a uniform, explicit, ... -
Wide-line and pulsed NMR instrumentation and investigations in certain Hydrazinium metal halides.
This thesis describes the wide-line and pulsed NMR instrumentation and investigations in certain hydrazinium double salts. Proton second moment and proton spin-lattice relaxation time as a function of temperature in the ... -
Wiener-hopf technique and allied methods in a class of scattering problems
This thesis is devoted to the study of a class of boundary value problems arising in the scattering of electromagnetic and acoustic waves by means of the Wiener–Hopf technique and related methods. The contents are organized ... -
X-Ray Crystallograhic Studies On 2',5', Cyclic And Modified Nucleotides
(2007-09-05)This thesis presents the crystal structures of 2', 5', cyclic and modified nucleosides / nucleotides. Chapter I gives a brief account of the structural studies on 2', 5' and modified nucleotides. It also presents a short, ... -
X-ray Crystallographic Characterization Of Designed Peptides Containing Heterochiral And Homochiral Diproline Segments And Database Analysis
(2010-12-30)Understanding the relation between amino acid sequences and protein structures is one of the most important problems in modern molecular biology. However, due to the complexities in the protein structure, this task is ... -
X-ray crystallographic investigations of some analgetic pyrazole derivatives and their crystalline complexes
This thesis reports the single?crystal X?ray diffraction studies on: Antipyrine, a 1:1 complex between antipyrine and salicylic acid (salipyrine), Amidopyrine, Phenylbutazone, and a 2:1 complex between phenylbutazone and ...
