Axially Symmetric Equivalents Of ThreeDimensional Rf Ion Traps
(20130913)This thesis presents axially symmetric equivalents of threedimensional rf ion traps. Miniaturization in mass spectrometry has focused on miniaturizing mass analyzers. Decrease in mass analyzer size facilitates reduction ... 
Bounded Analytic Functions On The Unit Disc
(20110809)In this thesis, we have dealt primarily with two function algebras. The first one is the space of all holomorphic functions on the unit disc D in the complex plane which are continuous up to the boundary, denoted by A(D). ... 
Conformation And Charge Transpsort In Conducting Polymers, Carbon Nanotubes And Their Nanocomposites
(20130502)The main motivation in this thesis is to compare the conformation and charge transport in conducting polymers and carbon nanotubes (CNTs) and to investigate those physical properties in their combined form of nanocomposites. ... 
Development Of Cu2ZnSnS4/ZnS Thin Film Heterojunction Solar Cells By Ultrasonic Spray Pyrolysis
(20130606)Semiconductors such as CuInGaSe2 and CdTe have been investigated as absorber layer materials for thin film solar cells since their band gap matches with the solar spectrum. Films as thin as 2m are sufficient for the ... 
Effects Of Disorder On Physical Properties Of Selected Transition Metal Oxides
(20130214)Disorder in materials often brings in new and exotic physical properties along with it. It is thus very important to study different kinds of disorder and their implications on various material properties. In this thesis, ... 
Electron Spin Resonance And Optical Studies On The Conducting Polymer Polyaniline
(20110711)For every phenomenon found in inorganic materials, organic counterparts have been found in the last 50 years. The discovery of metallic conductivity in the inorganic conjugated polymer (SN)x was a forerunner to the discovery ... 
Escape Of High Mass Ions Due To Initial Thermal Energy And Its Implications For RF Trap Design
(20130531)This thesis investigates the loss of high mass ions due to the initial thermal energy in ion trap mass analyzers. It provides an analytical expression for estimating the percentage loss of ions of a given mass at a particular ... 
Exploring Polynomial Convexity Of Certain Classes Of Sets
(20110718)Let K be a compact subset of Cn . The polynomially convex hull of K is defined as The compact set K is said to be polynomially convex if = K. A closed subset is said to be locally polynomially convex at if there ... 
HandMovement Prediction Using LFP Data
(20110808)The last decade has seen a surge in the development of BrainMachine Interfaces (BMI) as assistive neural devices for paralysis patients. Current BMI research typically involves a subject performing movements by controlling ... 
Investigating Systematics In The Cosmological Data And Possible Departures From Cosmological Principle
(20130611)This thesis contributes to the field of dark energy and observational cosmology. We have investigated possible direction dependent systematic signal and nonGaussian features in the supernovae (SNe) Type Ia data. To detect ... 
Ion Assisted Deposition Of HfO2 Thin Films For CMOS Gate Dielectric Applications
(20130913)The scaling down of Complementary Metal Oxide Semiconductor (CMOS) transistors to sub100nm requires replacement of conventional Silicon dioxide layer with high dielectric constant (K) material for gate dielectric. Among ... 
Magnetic And Transport Studies On Nanosystems Of Doped Rare Earth Manganites And VPP PEDOT
(20130610)The study of novel properties of materials in nanometer length scales has been an extensive area of research in the recent past. The field of nanosciece and nanotechnology deals with such studies and has gained tremendous ... 
Mathematical And Numerical Studies On The Inverse Problems Associated With Propagation Of Field Correlation Through A Scattering Object
(20110523)This thesis discusses the inverse problem associated with the propagation of field autocorrelation of light through a highly scattering object like tissue. In the first part of the thesis we consider the mathematical issues ... 
Nonequilibrium Fluctuations In Sedimenting And SelfPropelled Systems
(20130610)Equilibrium statistical mechanics has a remarkable property: the steady state probability distribution can be calculated by a procedure independent of the detailed dynamics of the system under consideration. The partition ... 
Novel Methods To Interrogate Fiber Bragg Grating Sensors
(20130214)A novel detection technique to estimate the amount of chirp in fiber Bragg gratings (FBGs) is proposed. This method is based on the fact that reflectivity at central wavelength of FBG reflection changes with strain/temperature ... 
Numerical Study of Directionality of Ion Ejection In Axially Symmetric Ion Traps
(20130213)In the normal operation of quadrupole ion trap mass spectrometers, the trapped ions are ejected symmetrically through both the upper (detector) and lower(source) endcap electrodes during mass selective boundary ejection ...
