Semi-empirical Studies Of Solar Supergranulation And Related Phenomena
(Physics, 2008-09-17)
In recent years, solar observations have moved from ground-based
telescopes to observatories on Earth orbiting satellites, such as
SOHO. They provide us with a clear and uninterrupted view of the
solar disk. One instrument ...
A Search For The Higgs Boson In Its Associated Production With A W Vector Boson in p¯p Collisions at √s = 1.96 TeV
(Physics, 2008-04-22)
We present the results of a search for the Standard Model Higgs boson in its associated
production with a W vector boson in p¯p collisions at √s = 1.96 TeV using the complete Run
IIA dataset with an integrated luminosity ...
Silicon Carbide Nanotubes: Promises Beyond Carbon Nanotubes
(Physics, 2008-09-17)
First-principles calculations for the electronic and geometric structures of three different types of armchair and zigzag silicon carbide nanotubes from (3, 3) to (11, 11) and (3, 0) to (11, 0) have been performed using ...
Moment Calculations For Low Energy Ions In Jupiter's Magnetotail From Nasa's New Horizons Mission
(Physics, 2009-09-16)
Jupiter's magnetosphere and magnetotail is the largest cohesive structure in our solar system which extends to the orbit of Saturn. One of NASA's objectives is to understand how universal bodies interact with its surroundings. ...
Can Silicon Carbide Nanotubes Be Effective Storage Medium For Hydrogen Storage?
(Physics, 2009-09-16)
A systematic study of molecular hydrogen adsorption on three different atomic configurations of armchair SICNTs has been performed. In the first stage of our study, first principles calculations using both density functional ...
Optical And Structural Properties Of Zinc Based Nanoparticles Depend On Temperature And Molar Concentration
(Physics, 2009-09-16)
Zinc based nanoparticles have great potential for use in radiation detection as well as uses in solid state lighting. In this thesis, we report the synthesis of ZnO: Eu3+ with the use of solid state diffusion at temperatures ...
First-principles Study On Hard/soft SmCo5/Co(Fe) Nanocomposite Magnetic Materials
(Physics, 2008-09-17)
More than a decade ago, exchange-spring permanent magnets containing soft and hard magnetic phases have been proposed to enlarge maximum energy product values through exchange coupling between the magnetically soft and ...
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 ...
