Undergraduate Music Student Stress and Burnout

Burnout is fatigue and diminished interest caused by long-term stress. It is characterized by emotional exhaustion, depersonalization, and lack of personal accomplishment. In the university music atmosphere, stress and burnout are prevalent and accepted as part of the culture. Symptoms and causes of general stress and burnout have been well researched, but much less has been presented on college musicians\u27 burnout, let alone how to deal with it. This study examines the sources of stress, burnout, and ways of coping for undergraduate music students. A questionnaire with both quantitative and open-ended questions was administered during the 2009 spring semester. Participants were undergraduate music majors attending a large urban university. The qualitative section revealed that the majority of survey participants attributed a high level of stress to their general undergraduate studies and to their music studies in particular. The mechanism rated most effective for alleviating stress was sleep, followed by spending time with family and friends, breathing exercises, exercise and eating well, meditation, and lastly, medical attention. The open-ended section revealed many music students were overburdened with schoolwork and music commitments. Many expressed that they had no time for things they enjoyed and had a need to learn better time management. Students also listed coping mechanisms not listed in the quantitative section

Non-equilibrium coherence dynamics of a soft boson lattice

We study the non-equilibrium evolution of the phase coherence of a Bose-Einstein condensate (BEC) in a one dimensional optical lattice, as the lattice is suddenly quenched from an insulating to a superfluid state. We observe slowly damped phase coherence oscillations in the regime of large filling factor (~100 bosons per site) at a frequency proportional to the generalized Josephson frequency. The truncated Wigner approximation (TWA) predicts the frequency of the observed oscillations.Comment: 10 pages. 4 figure

AGV Design

This report details the design and calculation work done towards creating an autonomous guided vehicle (AGV) for use in the steel and metal related industries. Steel Equipment Specialists (SES) is a major manufacturer of coil transportation vehicles for these industries. SES believes the future of coil transportation within the mills includes AGVs in some circumstances. The team was tasked with exploring the design and cost of a base model for use in future designs, since SES has not yet modeled or manufactured an AGV. This design was successful under the stress from the application in calculations, and the cost of the design was minimized, which resulted in a design which exceeded expectations. Safety was the most important factor for the team during design, and the safety features included should minimize injury due to machine design and function. Due to these accomplishments, SES considers the design successful

Virtuelle soziale Netzwerke - Nutzbarkeit für das Human Resource Management

Virtuelle soziale Netzwerke gewinnen im Bereich des Human Resource Managements an Bedeutung. In der vorliegenden Arbeit wird die Nutzbarkeit von virtuellen sozialen Netzwerken für das Human Resource Management systematisch untersucht. Die vorliegende Arbeit liefert zunächst theoretische Grundlagen in Bezug auf die verschiedenen Aufgabenfelder des Human Resource Managements und virtuelle soziale Netzwerke. Der Schwerpunkt der Arbeit liegt jedoch in der Rekonstruktion eines Lebenslaufs und einer Persönlichkeitseinschätzung mit Hilfe der Angaben aus virtuellen sozialen Netzwerken zu dieser Person.Virtual social networks and human resource management are becoming more and more important. The present work analyzes systematically the usability of virtual social networks with regard to human resource management. Firstly, the present work gives significant theoretical basics with regard to the different functions of human resource management. After that the present work gives theoretical basics with regard to virtual social networks. In this context the main focus is on the reconstruction of a curriculum vitae and a characterization of a personality on the basis of virtual social networks

X-band Dual Polarization Phased-Array Radar for Meteorological Applications

This dissertation details the development and operation of a novel dual-polarized Phase-Tilt Weather Radar (PTWR) designed for meteorological applications. The use of radar has a well-documented history in detection and classification of weather phenomena, but due to the limited mechanical scanning speed, its usage for severe weather observations remains far from ideal. The PTWR utilizes phased-array technology and provides unique capabilities such as smart scanning, fast scan update, and tracking. This technology is considered a candidate for a replacement and consolidation of the current US weather and surveillance radar networks. The dissertation can be divided into three parts. First, the hardware design of the radar is presented. Methods of an element and array calibration are discussed. The measured sidelobe level and pattern match exhibit satisfactory performance. The algorithms for signal processing in alternate transmit alternate receive mode of operation are described in detail. The PTWR weather detection capability is validated by an inter-comparison with a collocated X-band high-power radar. These tests showed correlation exceeding 90% for measurements of reflectivity in a convective storm system. The results support the hypothesis that phased-array technology poses an attractive solution for weather remote sensing. The second part addresses the radar waveform considerations. The sensitivity of the radar can be improved by several decibels by means of pulse compression techniques. This is necessary, since the PTWR utilizes low-power solid-state transmitters. The work discusses the trade-offs in waveform design and introduces a novel compression filter, which outperforms traditional window-based solutions. The pulse compression performance is validated using clutter data collected by the PTWR, proving that a deep sidelobe reduction in excess of 40dB can be achieved at the minimal penalty in signal-to-noise level (below 0.5dB). Finally, the third part focuses on the scanning geometry of a 1-D phase-tilt ar- chitecture. It is shown that as the elevation angle is increased, the measurements are affected by a self-induced apparent canting angle. The methods of polarization rotation correction are presented. The biases in typical weather radar products such as reflectivity, differential reflectivity, correlation coefficient, and specific propagation phase, are investigated. The analysis shows that for elevation angles below 15deg , the retrievals errors are acceptable
