Study Of Jet And Missing Transverse Energy Performance In Dijet Events With ATLAS Data
(Physics, 2012-04-11)
The Large Hadron Collider(LHC) is the world's largest particle collider at CERN, Geneva, operating at a center of mass energy of 7 TeV . The Toroidal LHC Apparatus (ATLAS)is one of two general purpose detectors at the LHC. ...
First Principles Study Of Properties Of The Oxidized Cu(100) And Cu(110)
(Physics, 2013-07-22)
Copper based catalysts are of importance to a number of industrial processes including the synthesis of methanol, the reduction and decomposition of nitrogen oxides, and treatment of waste water. In copper catalysis surface ...
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 ...
Atomic And Molecular Adsorptions Of Hydrogen And Oxygen On Silicon Nanotubes: An Ab Initio Study
