Case Studies Of The Circular Restricted Three Body Problem
(Physics, 2007-08-23)
In this thesis, the onset of instability for a planet which is part of a stellar binary system is investigated by running numerical simulations of the circular restricted three body problem. This study also makes use of a ...
Synthesis And Characterization Of Magnetic Nanoparticles
(Physics, 2007-08-23)
Synthesis of uniform nanoparticles (<100 nm) of hard and soft magnetic materials have attracted much attention in the last two decades because of their unique magnetic properties and potential for many applications such ...
On A Class Of ABCS
(Physics, 2007-08-23)
The local density approximation to density functional theory (LDA-DFT) has been used to study the different possible relaxations and reconstructions of In-rich InSb (100) surface. Various electronic and geometric structure ...
Effects Of Temperature Gradients On Transverse Oscillations Of Solar Magnetic Flux Tubes
(Physics, 2007-08-23)
Solar magnetic flux tubes support three fundamental modes: longitudinal, transverse and torsional tube waves. Previous studies showed that the propagation of longitudinal and transverse waves along thin and isothermal ...
Conditions For Wave Propagation Along Solar Magnetic Flux Tubes
(Physics, 2007-08-23)
There is an intimate relation between all aspects of the solar activity and the presence of solar magnetic fields. Observations showed that the magnetic field at the photospheric level consists of magnetic flux tubes, which ...
AlfvÉnic Accelerated Electrons And Short Burst Auroral Kilometric Radiations Observed By The Fast Satellite
(Physics, 2007-09-17)
This investigation is motivated by previous study of short burst radiations (S-bursts) reported by Ergun et al. [2006], who suggested two generation mechanisms of S-bursts: one is the electron cyclotron maser instability ...
A First-principles Study On The Enhancement Of Beryllium Doping In Gallium Nitride
(Physics, 2007-08-23)
The excellent physical and electrical properties of Gallium Nitride (GaN) have made it a good candidate in light-emitting diodes and UV detecting semiconductor materials. However, GaN's p-type doping has long been a ...
A First-principles Study On Bulk CuO: Electronic Structures And Native Point Defects
(Physics, 2007-08-23)
In this thesis, we have performed a first-principles study on strongly correlated monoclinic cupric oxide (CuO) by using the LSDA+U method implemented in the PAW method. Based on the optimized structural parameters, which ...
On The Behavior Of The 5f Electrons
(Physics, 2007-08-23)
Considerable theoretical efforts have been devoted in recent years to studying the electronic and geometric structures and related properties of surfaces to high accuracy. One of the many motivations for this burgeoning ...
Derivation Of Generalized Lorenz Systems To Study The Onset Of Chaos In High Dimension
(Physics, 2007-08-23)
This thesis provides a new method to derive high dimensional generalized Lorenz systems. Lorenz system is a celebrated nonlinear dynamical dissipative system which was originally derived by Lorenz to study chaos in weather ...
