Hilbert Space Theory And Applications In Basic Quantum Mechanics, 2013 California Polytechnic State University
Hilbert Space Theory And Applications In Basic Quantum Mechanics, Matthew Gagne
We explore the basic mathematical physics of quantum mechanics. Our primary focus will be on Hilbert space theory and applications as well as the theory of linear operators on Hilbert space. We show how Hermitian operators are used to represent quantum observables and investigate the spectrum of various linear operators. We discuss deviation and uncertainty and briefly suggest how symmetry and representations are involved in quantum theory.

Electric Currents Due To Stress-Activated Positive Hole Charge Carriers In Ice, 2012 California Polytechnic State University
Electric Currents Due To Stress-Activated Positive Hole Charge Carriers In Ice, Cary T. Keller P.E., Friedemann T. Freund, Dale P. Cruikshank
STEM Teacher and Researcher (STAR) Program Posters
Jupiter’s satellite Europa, whose surface is composed of ice with a possible water ocean beneath, could conceivably serve as an abode for extraterrestrial life. This and other icy celestial bodies may contain organic macromolecular solid material that is produced when surface ices are exposed to ultraviolet radiation and/or electrical energy. Tidal and tectonic stresses or meteorite impacts in icy crusts may produce electrical discharges, which would provide the energy for in-situ synthesis of the organic solids. This electrical energy can be provided by positive hole charge carrier activation. Positive holes exhibit properties such as the ability to flow ...
Accelerated Monte Carlo Based Simultaneous Dual-Isotope Spect Reconstruction, 2012 McMaster University
Accelerated Monte Carlo Based Simultaneous Dual-Isotope Spect Reconstruction, Muhammad Irfan Karamat
Open Access Dissertations and Theses
Simultaneous dual-isotope SPECT imaging has a number of applications, for exam- ple, cardiac, brain and cancer imaging. The major concern in simultaneous dual- isotope SPECT is the significant crosstalk contamination between the different isotopes used. The current study focuses on a method of crosstalk compensation between two isotopes in simultaneous dual isotope SPECT acquisition applied to cancer imaging using 99mTc/111In and breast SPECT using 99mTc/123I. Monte Carlo (MC), which is thought to offer the most realistic crosstalk and scatter compensation modelling, in typical implementations, has inherent long calculation times (often several hours or days ...
Anisotropic Diffusivity Of The Prismatic Surface Of Ice Is Model Independent, 2012 University of Puget Sound
Anisotropic Diffusivity Of The Prismatic Surface Of Ice Is Model Independent, Natalie D. Bowens
In simulations reported by Gladich et al., the surface diffusion on the prismatic surface of ice was found to be anisotropic at low temperatures and isotropic at high temperatures in the NE6 model. Our research investigated whether this effect is a true property of ice, or an artifact of NE6 model, by using the TIP4P/2005 and the TIP5P-EW representations. It was found that anisotropy of surface diffusion on the Prismatic facet at low temperatures is model independent. An Arrhenius analysis was also preformed to find the activation energies of diffusion in both models.
Examination Of Bystander Cell Death Following Low-Let Irradiation, 2011 McMaster University
Examination Of Bystander Cell Death Following Low-Let Irradiation, Michael D. Gow
Open Access Dissertations and Theses
This thesis describes an analysis of the influence of dose and dose rate from low LET radiation on the induction of a cytotoxic bystander effect. The general direction was as follows:
a) Utilize a well – established reporter cell line with two types of low – LET radiation across varying dose and dose rates in order to assess the possibility of a dose rate effect. These results identified the recovery of bystander cell survival to control levels after high dose treatment. Additionally, dose rate effects were seen at high dose treatments following electron irradiation as well as between similar low – LET sources ...
Assessment Of Collimator Jaw Optimization In Reducing Normal Tissue Irradiation With Intensity Modulated Radiation Therapy, 2011 Texas Medical Center Library
Assessment Of Collimator Jaw Optimization In Reducing Normal Tissue Irradiation With Intensity Modulated Radiation Therapy, Sarah Joy
UT GSBS Dissertations and Theses (Open Access)
Purpose: To evaluate normal tissue dose reduction in step-and-shoot intensity-modulated radiation therapy (IMRT) on the Varian 2100 platform by tracking the multileaf collimator (MLC) apertures with the accelerator jaws.
Methods: Clinical radiation treatment plans for 10 thoracic, 3 pediatric and 3 head and neck patients were converted to plans with the jaws tracking each segment’s MLC apertures. Each segment was then renormalized to account for the change in collimator scatter to obtain target coverage within 1% of that in the original plan. The new plans were compared to the original plans in a commercial radiation treatment planning system (TPS ...

The Textural Discontinuity Hypothesis And Its Relation To Nomadism, Migration, Decline, And Competition, 2010 University of Nebraska - Lincoln
The Textural Discontinuity Hypothesis And Its Relation To Nomadism, Migration, Decline, And Competition, Aaron L. Alai
Dissertations & Theses in Natural Resources
The causes of nomadism, migration, and decline in vertebrates are debated issues in the ecological sciences. Literature suggests nomadism may arise in species that specialize in granivory, nectivory, or the utilization of rodent outbreaks. Migration is thought to arise as a result of the exploitation of certain scarce or variable food resources. Species decline is hypothesized to be the result of many different factors as well; large species, island species and specialists may be more prone to decline.
A fresh perspective regarding the causes for species nomadism, migration, and decline is being investigated utilizing the ideas within the Textural Discontinuity ...
An Investigation Of Gas Bubble Generation And Measurement In Water And Mercury, 2010 University of Tennessee, Knoxville
An Investigation Of Gas Bubble Generation And Measurement In Water And Mercury, Stuart A Walker
The pressure increase attributed to the energy deposition in the liquid metal target of the Spallation Neutron Source results in cavitation and pitting erosion of the target pressure boundary. Introducing compressibility in the form of small gas bubbles will extend the lifetime of the target vessel. The pressure rise caused by the beam energy deposition occurs in one microsecond, which encourages use of bubbles of radius less than 20 microns, such that the bubble response to pressure change is adequately fast. Gas volume fraction near 0.5% is sufficient to accommodate the mercury volumetric expansion and reduce the pressure rise ...
Software Internationalization: A Framework Validated Against Industry Requirements For Computer Science And Software Engineering Programs, 2010 California Polytechnic State University
Software Internationalization: A Framework Validated Against Industry Requirements For Computer Science And Software Engineering Programs, John Huan Vu
Master's Theses and Project Reports
In 2001, the ACM and IEEE Computing Curriculum stated that it was necessary to address "the need to develop implementation models that are international in scope and could be practiced in universities around the world." With increasing connectivity through the internet, the move towards a global economy and growing use of technology places software internationalization as a more important concern for developers. However, there has been a "clear shortage in terms of numbers of trained persons applying for entry-level positions" in this area. Eric Brechner, Director of Microsoft Development Training, suggested five new courses to add to the computer science ...

University of Kentucky Doctoral Dissertations
The experiment E06010 measured the target single spin asymmetry (SSA) in the semiinclusive deep inelastic (SIDIS) n↑(e,éπ¯)X reaction with a transversely polarized 3He target as an effective neutron target. This is the very first independent measurement of the neutron SSA, following the measurements at HERMES and COMPASS on the proton and the deuteron. The experiment acquired data in Hall A at Jefferson Laboratory with a continuous electron beam of energy 5.9 GeV, probing the valence quark region, with x = 0.13→0.41, at Q2 = 1.31→3.1 GeV2. The two contributing ...
Measurement Of Single Spin Asymmetries In Semi-Inclusive Deep Inelastic Scattering Reaction N↑(E, Éπ+)X At Jefferson Lab, Kalyan C. Allada
University of Kentucky Doctoral Dissertations
What constitutes the spin of the nucleon? The answer to this question is still not completely understood. Although we know the longitudinal quark spin content very well, the data on the transverse quark spin content of the nucleon is still very sparse. Semi-inclusive Deep Inelastic Scattering (SIDIS) using transversely polarized targets provide crucial information on this aspect. The data that is currently available was taken with proton and deuteron targets.
The E06-010 experiment was performed at Jefferson Lab in Hall-A to measure the single spin asymmetries in the SIDIS reaction n↑(e,éπ±/K±)X using transversely polarized 3He target ...
