Nonlinear Dynamics Of Resonances In, And Ejection From Paul Traps
(2008-09-26)This thesis presents results of investigations that have been carried out to understand dynamics in nonlinear Paul trap mass spectrometers. Of the three problems that have been taken up for study in this thesis, the first ... -
Nonlinear propagation of intense electromagnetic waves in quasar and pulsar plasmas
his thesis presents the results of analytical as well as numerical investigations of radiation–plasma interaction instabilities in astrophysical plasmas. It consists of two introductory chapters, four main chapters, and ... -
Nonlinear wave propagation in muln dimensions
This thesis consists of four chapters including a chapter on general introduction and deals with some problems in nonlinear wave propagation in multi-dimensions. The problems are: nonlinear wave propagation in a two-dimensional ... -
Nonreciprocity, condensation and chirality in active granular systems
We present a journey into the rich non-equilibrium phenomena of active granular systems, a versatile model for studying “living” materials. Our exploration begins with the discovery of non-reciprocal, medium-mediated ... -
Normal Spectrum of a Subnormal Operator
(2018-03-21)Let H be a separable Hilbert space over the complex field. The class S := {N|M : N is normal on H and M is an invariant subspace for Ng of subnormal operators. This notion was introduced by Halmos. The minimal normal ... -
Novel Diffraction Based Deflection Profiling For Microcantilever Sensor Technology
(2015-02-04)A novel optical diffraction based technique is proposed and demonstrated to measure deflections of the order of ~1nm in microcantilevers (MC) designed for sensing ultra-small forces of stress. The proposed method ... -
Novel Methods To Interrogate Fiber Bragg Grating Sensors
(2013-02-14)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 ... -
Novel Micro fluidic Techniques for Point-of-Care Diagnostics
Point-of-care Diagnostics (POCD) is one of the rapidly growing areas of health-care sector that avails to the needs of the patient at the point-of-care. An ideal POCD device is required to be compact, portable, offer ... -
Novel Pathways for Beyond Standard Model Physics
In the light of discovering the Higgs boson and null results at the LHC, we look for new pathways for Beyond Standard Model Physics, which could accommodate at least one of the Standard Model shortcomings. (i) Unification ... -
Novel Spectral Processing Methods in NMR – Wavelet Transform and Pattern Based Analysis
NMR spectroscopy provides a variety of information leading to an understanding of the properties of different materials. To extract this information from the experiments, one needs to have noise and artifacts free spectra ... -
Novel spin, charge, and lattice dynamics in pyrochlore iridates : Raman and X-ray diffraction studies at low temperatures and high pressure
This thesis investigates phonon dynamics, electronic, and spin excitations along with structural instabilities and phase transitions in rare earth pyrochlore iridates, A2Ir2O7 (A = Pr, Gd, Dy, and Er) and Bi-doped Sm2Ir2O7 ... -
Novel Upwind and Central Schemes for Various Hyperbolic Systems
(2018-05-21)The class of hyperbolic conservation laws model the phenomena of non-linear wave propagation, including the presence and propagation of discontinuities and expansion waves. Such nonlinear systems can generate discontinuities ... -
