Developments in two dimensional NMR spectroscopy of multiple quantum coherences of couples spins in liquids
The pathway description provides a straightforward method of computing flip-angle dependence of various multiple quantum coherences in the 2D MQ and the 2D COSY spectroscopy. Using this flip-angle dependence it is possible ... -
Ergodic and adaptive control of markov processes.
We address the problem of controlling two classes of Markov processes, viz., Markov chains and diffusion processes. Our main goal is to minimize a long-run average cost criterion (or ergodic cost criterion) associated with ... -
Hysterisis in model spin systems.
In this thesis a systematic study of hysteresis in model spin systems is undertaken by constructing the first statistical-mechanical theory wherein spatial fluctuations of the order parameter are incorporated. The theory ... -
Nuclear magnetic resonance investigations of certain protonic conductors.
Ionic motion in the hydrate of ammonium ferrocyanide has been investigated by high?pressure wide?line NMR, high?resolution NMR and conductivity techniques. In the high?pressure NMR study, the room?temperature proton NMR ... -
Numerical studies of unsteady double diffusive mixed convective boundary_layer flows
In the present thesis, some problems in unsteady mixed convective boundary-layer flows with double diffusion have been numerically investigated. It consists of five chapters-the first of which is a general introduction to ... -
Study of giant radio galaxies.
Within the framework of the beam model, we have deduced some basic physical parameters of the jets and hotspots associated with classical double radio sources, following a simple approach which is based on the assumptions ... -
Swiriling flows between rotating coaxial and non-coaxial disks
In this thesis an attempt is made to study some steady and unsteady flow problems due to a single rotating disk and two disks rotating coaxially or non-coaxially in different fluid media in a variety of interesting situations. ... -
