On Influence

On Influence seeks to explore the varied inspirations that have framed our own learning, research, and teaching experiences. At the core of the exhibit is the question: What led you to your field of study? The exhibit reflects upon the varied influences on both research and teaching. It includes narratives from members of the UT community about their own research trajectories. On Influence also considers the inspirations that have helped define my values and goals as a teacher in order to help my students examine their own perceptions about the Middle Ages. The narratives and objects collected in this exhibit are not offered as research but rather as reflections.UT LibrariesUT Librarie

Optical Properties of Quantum-Dot-Doped Liquid Scintillators

Semiconductor nanoparticles (quantum dots) were studied in the context of liquid scintillator development for upcoming neutrino experiments. The unique optical and chemical properties of quantum dots are particularly promising for the use in neutrinoless double beta decay experiments. Liquid scintillators for large scale neutrino detectors have to meet specific requirements which are reviewed, highlighting the peculiarities of quantum-dot-doping. In this paper, we report results on laboratory-scale measurements of the attenuation length and the fluorescence properties of three commercial quantum dot samples. The results include absorbance and emission stability measurements, improvement in transparency due to filtering of the quantum dot samples, precipitation tests to isolate the quantum dots from solution and energy transfer studies with quantum dots and the fluorophore PPO.Comment: version 2, minor text update

Apartment house Ostrava

Import 23/08/2017Předmětem bakalářské práce „Bytový dům Ostrava“ je vypracování projektové dokumentace pro provádění stavby. Objekt se nachází na ulici Purkyňova poblíž Masarykova náměstí v historickém centru Moravské Ostravy. Hlavní myšlenkou bylo nahradit stávající a nevhodnou zástavbu, ucelit tak blok a zkultivovat prostor kolem Katedrály Božského Spasitele. Objekt je navržený tak, aby nezasahoval do přirozených cest a aby výškově ladil s okolními budovami. V prvním podlaží se nachází knihovna, kavárna a zázemí bytů. Ve druhém, třetím a čtvrtém podlaží se nachází celkem 9 bytů. V pátém podlaží je ateliér kresby. Návrh je zaměřen na zvýšení kvality žití a podporu komerčního a kulturního potencionálu dané lokality.The subject of the bachalor thesis „Apartment house Ostrava“ is to create a project documentation for realization of the construction. The object is located in the street Purkyňova near of the historic center of Moravian Ostrava. Main idea was replace existing and improper area, fill the city block and cultivate an area around the Cathedral of the Divine Savior. The object is designed to not encroach to natural ways and that height harmonize with neighboring buildings. On the first floor there is a small library, coffee shop and a base of flats. On the second, third and fourth floors there are nine apartments. On the fifth floor is the drawing studio. The design is focused on improving the quality of life and promoting the commercial and cultural potential of the site.226 - Katedra architekturydobř

Zukünftige Entwicklung des Güterverkehrs : Sind Sättigungsgrenzen erkennbar?

Seit Jahrzehnten zeigt der Güterverkehr in Deutschland und in den wichtigsten EU-Staaten ein starkes Wachstum, welches seit einigen Jahren das des Perso-nenverkehrs deutlich übertrifft. Diese Wachstumsdynamik des Güterverkehrs wird kritisch gesehen: Die Kapazitätsengpässe in der Verkehrsinfrastruktur wer-den durch den Güterverkehr nachhaltig verschärft. Die Verteilung der Nachfrage nach Güterverkehrsleistungen auf die einzelnen Verkehrsträger ist sehr unter-schiedlich; eine stark einseitige Ausrichtung auf den Straßenverkehr verschärft dort die Kapazitätsprobleme in besonderem Maße. Vor allem im Straßenverkehr stellt der Gütertransport eine bedeutende Quelle für Umweltbelastungen durch Lärm und Schadstoffe sowie auch CO2-Emissionen dar. Insofern aktualisiert sich die Frage, ob in Zukunft Sättigungsgrenzen, vielleicht sogar Rückbildungseffekte, beim Güterverkehr zu erwarten sind. Dieser Frage wird nachfolgend nachgegangen. --

Transit Time and Charge Correlations of Single Photoelectron Events in R7081 PMTs

During the calibration phase of the photomultiplier tubes (PMT) for the Double Chooz experiment the PMT response to light with single photoelectron (SPE) intensity was analysed. With our setup we were able to measure the combined transit time and charge response of the PMT and therefore we could deconstruct and analyse all physical effects having an influence on the PMT signal. Based on this analysis charge and time correlated probability density functions were developed to include the PMT response in a Monte Carlo simulation.Comment: minor changes by referee reques

Large scale Gd-beta-diketonate based organic liquid scintillator production for antineutrino detection

Over the course of several decades, organic liquid scintillators have formed the basis for successful neutrino detectors. Gadolinium-loaded liquid scintillators provide efficient background suppression for electron antineutrino detection at nuclear reactor plants. In the Double Chooz reactor antineutrino experiment, a newly developed beta-diketonate gadolinium-loaded scintillator is utilized for the first time. Its large scale production and characterization are described. A new, light yield matched metal-free companion scintillator is presented. Both organic liquids comprise the target and "Gamma Catcher" of the Double Chooz detectors.Comment: 16 pages, 4 figures, 5 table
