Numerical Simulations of Giant Planetary Core Formation
(2012-08-28)
In the widely accepted core accretion model of planet formation, small rocky and/or icy bodies (planetesimals) accrete to form protoplanetary cores. Gas giant planets are believed to have solid cores that must reach a ...
Gas Ejection from Spiral Galaxy Disks
(2012-01-06)
We present the results of three proposed mechanisms for ejection of gas from a spiral arm into the halo. The mechanisms were modelled using magnetohydrodynamics (MHD) as a theoretical template. Each mechanism was run ...
Dyadic Green Functions and their applications in Classical and Quantum Nanophotonics
(2012-04-26)
Research in solid-state nanophotonics and quantum optics has been recently pushing the limits in semiconductor microcavity design. High quality microcavities that confine light into small volumes are now able to drastically ...
A detailed observational analysis of magnetism in three B and O stars observed within the context of the MiMeS project
(2012-09-28)
The detailed observational analysis of three massive B- and O-type stars was carried out in this study in order to characterize their fundamental, magnetic, and variability properties. The bulk of the data acquired were ...
Computational study of rovibrational spectra of Van der Waals dimers and their isotopologues
(2012-08-29)
A new intermolecular potential energy surface, rovibrational transition frequencies, and line strengths are computed for OCS-OCS and CO2-CS2. The potentials were made by fitting energies obtained from explicitly correlated ...
Persistent currents in bosonic mixtures in the ring geometry
(2012-03-28)
The present thesis is devoted to an analysis of the possibility of Bose condensates
supporting persistent currents in the ring geometry. Our analysis is based on an
approach developed by F. Bloch which focuses on the ...
Magnetic fields and the variable wind of the early-type supergiant β Ori
(2012-04-30)
Supergiant stars of spectral types B and A are characterized by variable and structured winds, as revealed by variability of optical and ultraviolet spectral lines. Non-
radial pulsations and magnetically supported loops ...
Tomographic Imaging on a Cobalt Radiotherapy Machine
(2012-02-06)
Cancer is a global problem, and many people in low-income countries do not have access to the treatment options, such as radiation therapy, that are available in wealthy countries. Where radiation therapy is available, it ...
Understanding Magnetic Flux Leakage from Gouges and Dents Containing Gouges
(2012-01-30)
Magnetic flux leakage (MFL) is the most widely used non-destructive evaluation (NDE) technique for operating gas and oil transmission pipelines. The Queen’s Applied Magnetics Group (AMG) has been studying MFL signals from ...
The Rayleigh ratio measurement for SNO+ liquid scintillator and background studies of the internal ropes
(2012-09-10)
As a successor of the Sudbury Neutrino Observatory, the SNO+ experiment is planned
to start data taking in early 2013. Making use of the liquid scintillator, Linear
Alkylbenzene (LAB), the SNO+ experiment aims to perform ...
