Item Hydrostatic Transmission for Wind Power Generation RS-0008-09(2010) Thul, Brenen; Dutta, Rahul; Stelson, Kim; Bohlmann, Brad; Gust, Mike; Kildegaard, ArneThe University of Minnesota is performing research on the application of continuously variable hydrostatic transmissions for wind turbines. By replacing the gearbox of traditional wind turbines with a continuously variable hydrostatic transmission (HST), the rotor speed could be controlled independent of the generator speed. This would allow the use of more conventional synchronous generators instead of higher cost variable speed permanent magnet generators, and eliminate the need for power electronics. The gearbox of traditional wind turbines is one of the primary sources of premature failure and maintenance. HSTs have been the dominant choice for propulsion in agricultural, construction, forestry, and mining vehicles for more than half a century. Thus, replacing the gearbox in a wind turbine with an HST should improve the reliability of the machine. The IREE seed funding will be used by the University of Minnesota to begin the process of building a lab scale (50 kW) test stand to perform research on applying HSTs to wind turbines. The research will initially focus on determining the best drivetrain hardware configuration as well as on optimizing the wind turbine’s control algorithm.Item Interview with John Q.

Desirable polymers have a small band gap and a low HOMO energy level. Methods of finding this band gap exist using density functional theory (DFT) by calculating the energy gaps of increasing oligomer lengths (n), and plotting the HOMO-LUMO gap (in eV) as a function of the reciprocal polymer length (1/n). This method, however, proves time consuming and computationally costly. An alternative, less time-consuming method using periodic boundary conditions (PBC) exists. In our research, we studied existing donor-acceptor polymers from the literature and used PBC to calculate their band gaps for comparison with experimental data. To perform these calculations we used DFT at the B3LYP/3-21G(d) level of theory on optimized dimers. The PBC method yields results consistent with experimental values and can be useful in determining theoretical band gaps prior to synthesis which can aid in saving valuable lab time.Item Renewable Energy and Sustainable Chemistry Across the Undergraduate Chemistry Curriculum(2010) Pappenfus, Ted M.; Carpenter, Nancy E.; Soderberg, Timothy J.; Power, Caleb; Koehn, Ryan E.; Schmidt, JenniferIssues of energy and sustainability are having a direct impact on the public and are capturing the interests of many. As result, it is no surprise that science, including the field of chemistry, will become more connected with society in the future. To address this connection, we are in the process of integrating important elements of renewable energy and sustainable chemistry across the undergraduate chemistry curriculum at the University of Minnesota, Morris. This project strives to create a curriculum which is more interdisciplinary with respect to both teaching and research and which introduces topics that are timely, yet essential in preparing undergraduate students. Our initial efforts are focused on three key areas: (i) developing new courses in renewable energy and sustainability; (ii) integrating photovoltaics across the undergraduate curriculum; and (iii) illustrating the role of biochemistry in renewable energy and sustainability. Our goal is to develop a far-reaching energy and sustainable chemistry curriculum that complements the traditional curriculum and better prepares our future graduates for success in addressing global problems. An overview of the project will be presented along with our preliminary results.Item Title IX Self-Evaluation, University of Minnesota, The Coordinate Campuses: Crookston, Duluth, Morris, Waseca (1976-07)(1976)A workshop designed to explain the implications of Title IX and to initiate the self-evaluation process was held on each coordinate campus in March of 1976. It was conducted by Vice President Walter Bruning; Lillian H. Williams, Director of the Office of Equal Opportunity and Affirmative Action; Ann M. Pflaum, Title IX Coordinator; and Gary Engstrand, Athletics Consultant. Each coordinate campus established its own unit committees to generate information, as required by the 95 questions and the regulations. The responses were reviewed first by the Coordinate Campus Policy Review Committee and then by the Vice Presidents' Policy Review Committee from an institution wide perspective. All of the policies relevant to the institutional self-evaluation under Title IX are system-wide University policies governing activities in all locations. Because the four coordinate campuses are administered with substantial autonomy and fulfill missions distinctive from those of the Twin Cities Campus, however, each coordinate campus was asked to establish its own policy reveiw [sic] committee. Each conducted its own campus review and reported to the Vice Presidents' Policy Review Committee. The results are therefore reported in two forms in the University self-evaluation: as campus reports on the complete range of regulations and as portions of the reports on specific sections of the regulations (e.g., housing). Reports of the individual coordinate campuses follow this introduction. This summary will not duplicate the detailed information available elsewhere in the report, but it will provide a general overview of the self-evaluation process and the compliance activities on the coordinate campuses.Item University of Minnesota Morris Teacher Education Retention Survey(2016-04) Koehler, JanaThe purpose of this study was to determine if the University of Minnesota, Morris (UMM) teacher education graduates retention rates fall in line with the research that has previously been conducted.
