Computer simulation of functional materials for therapeutic ultrasound applications
(2015-01-13)
Magnetic resonance imaging guided high intensity focused ultrasound is a potential
non-invasive treatment which uses constructive interference patterns to concentrate
ultrasound energy generated by a piezoelectric ...
An ytterbium-doped fiber laser at 1.1 um
(2013-02-12)
A pulsed ytterbium-doped fiber laser is proposed and developed. A length of
samarium-doped fiber was inserted into the laser cavity to induce passive Q-switching.
The laser oscillated in the continuous wave, Q-switched ...
Microscopic modeling of high-field charge transport in amorphous selenium
(2014-01-22)
Avalanche multiplication of charge carriers as a result of successive impact ionization has led to the development of solid state avalanche photo-detectors. Crystalline based avalanche photodiodes have found a variety of ...
Pinning of magnetic vortices subject to multi-well potential in the Ginzburg-Landau theory of superconductivity
(2012-11-10)
I will study the existence of multi-vortex solutions of the Ginzburg-Landau equations with an external potential on R2. These equations model the equilibrium states of superconductors: the external potential, W, represents ...
Tunable high-power fiber laser and its application to produce Brillouin fiber lasers
(2012-11-10)
A tunable continuous wave single-longitudinal-mode fiber laser is proposed and
developed. A saturable absorber, as well as, an all-fiber Fabry-Perot filter was used in the
laser cavity to reduce mode-hopping. The laser ...
Plasmonic nanostructure on a tapered fiber for chemical detection
(2017)
A simple, cost effective technique to manufacture plasmonic nanostructures as a Surface Enhanced Raman Spectroscopy (SERS) substrate was investigated. The plasmonic structure of gold nanorods was developed on the surface ...
Proton NMR spectral study of UV treated live Escherichia coli Bacteria / by Michael Sorokopud.
(2010)
The lethal effects of ultraviolet radiation on microorganisms have been known and utilized for many years. In sufficiently high photon fluences, light and in particular, UV light, is an effective and subtle means of killing ...
Lead oxide (PbO) for direct conversion fluoroscopic detectors
(2012)
Polycrystalline Lead Oxide (PbO) is being investigated as a photoconductive
materials for application as X-ray-to-charge transducer in direct conversion x-ray
detectors used in fluoroscopy and radiology. Previous usage ...
Correspondence rules in SU (3)
(2018)
In this thesis, I present a path to the correspondence rules for the generators of the su(3) symmetry and
compare my results with the SU(2) correspondence rules. Using these rules, I obtain analytical expressions
for the ...
S U (3) Squeezing: quantum and semiclassical evolutions
(2013-02-03)
In this thesis we describe a squeezing for SU(3) systems and compare squeezing in the phase space in the semiclassical approximation with squeezing obtained by the full quantum mechanical calculation. We show that the ...
