Adaptive Critic Based Neurocontroller For Turbogenerators With Global Dual Heuristic Programming, Ganesh K. Venayagamoorthy, Donald C. Wunsch, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Turbogenerators are nonlinear time varying systems. This paper presents the design of a neurocontroller for such a turbogenerator that augments/replaces the traditional automatic voltage regulator (AVR) and the turbine governor using a novel technique based on the adaptive critic designs (ACDs) with emphasis on global dual heuristic programming (GDHP). Simulation results are presented to show that the neurocontroller derived with the GDHP approach is robust and its performance is better when compared with that derived with other neural network technique, especially when system conditions and configuration changes.

Analysis Of A Novel Four-Level Dc/Dc Boost Converter, Keith Corzine, Sonal K. Majeethia

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, novel two-quadrant buck/boost and one-quadrant boost four-level DC/DC power converters are introduced. The primary application for these converters is that of interfacing a low-voltage DC source, such as a fuel cell or battery, to a high-voltage four-level inverter. One important feature of the four-level DC/DC power converters proposed is the ability to perform the power conversion and balance the inverter capacitor voltages simultaneously. With the capacitor voltage balancing, it is possible to obtain the full voltage from the inverter. For the boost converter, the steady-state and nonlinear average-value (NLAM) models are developed. The NLAM is verified against …

Claiming The Victim: Tokenism, Mourning, And The Future Of German Holocaust Poetry, Kathrin M. Bower

Languages, Literatures, and Cultures Faculty Publications

This excerpt from Nelly Sachs's poem "You Onlookers" could be read as support for the contention, reportedly made by Adolf Hitler during a table talk, that "The Jews invented conscience." This statement, although fascinating in itself for what it implies about Hitler's psyche and moral sense, becomes even more provocative if read in association with Marina Zwetajewa's puzzling proclamation, made famous by its appearance as an epigram to a poem by Paul Celan, that "all poets are Jews." The connection of Jews to both conscience and poetry has significant repercussions for the genre of so-called Holocaust lyric, so-called because it …

Principal Succession: Realities Encountered By Successor Principals During The Succession Process, Kenneth Lester Rigdon

Dissertations and Theses @ UNI

In order to better understand the realities of principal succession (an interactive sequencing process for changing school administrators) it was the purpose of this study to examine the relationship between four organizational frames (structural, human resource, political, and symbolic) delineated by Bolman and Deal (1997) and three traits noted in the literature as evident during school principal succession (predecessor leave-taking, succession source, and experience). There is little research regarding school principal succession, and concern exists regarding the adequacy of transition practices within organizations. A questionnaire was employed to survey all school principals in the state of Kansas who succeeded during …

The Freshman Connection: Implementing And Assessing A Plan To Increase Student Success, Pamela Downing-Hosten

Abraham S. Fischler College of Education ETD Archive

The purpose of this practicum was to develop, implement, and assess a plan for reducing the number of freshmen at the high school who failed the grade, with failure being defined as the inability to earn 4 credits within 1 year. From the 1993-1994 school year until the 1997-1998 school year, an average of 17.7% of the 9th-grade class had to repeat the grade. Through the year-long implementation of the plan called the Freshman Connection program, the researcher hoped that the failure rate of 21.9% in 1998 would be reduced to 10.0% in 1999.

The Freshman Connection program entailed (a) …

Civilian Conservation Corps Rubble And Masonry Dams And Gully Morphology In Northeastern Iowa, Timothy Robert Beerman

Dissertations and Theses @ UNI

The Civilian Conservation Corps (CCC) was created in 1933 in an effort to help solve the problems associated with the lack of jobs for young men, the nations dwindling natural resources, and problems associated with soil erosion. The CCC's work in Iowa was primarily in the areas of reforestation and erosion control. Company 1749 of Cresco, Iowa stands out as an example of how the CCC worked to halt erosion. As a part of their erosion-control strategy, Company 1749 built a large number of rubble and masonry dams on gullies. These dams were designed to trap sediments and prevent further …

A Survey Of Iowa High School Band Directors And Their Students On The Occurrences Of Performing On A Musical Instrument While Experiencing Pain, Crystal M. Franzen Halverson

Dissertations and Theses @ UNI

Learning to play a musical instrument is a challenging and exciting venture for many children. Lessons are the primary means for children to learn to play a musical instrument. Some begin studying an instrument through private lessons and others through a Suzuki program. Many other children begin their study of a musical instrument in the public school system with a music teacher in elementary, junior high, or middle school. Regardless of how one begins to learn to play a musical instrument, by the time high school is reached, it is conceivable that he or she will have had at least …

The Self-Destruction Of Yugoslavia, Dejan Guzina

Political Science Faculty Publications

The self-destructiveness of the former Yugoslav federal system has not yet received its appropriate place in numerous accounts of the causes of Yugoslavia’s disintegration. This essay explores the self-destructive mechanism of the former Yugoslav socialist federal system. Its main thesis is that it was the institutional composition of the former Yugoslavia that was largely responsible for the cleavages in the 1980s, which caused the mutually exclusive ethnic nationalisms of today. In other words, the crisis, the subsequent ethnonational homogenization and the dissolution of the federal state were a natural outcome of the constitutional foundations of the system. When in the …

State of the Region Reports: Hampton Roads

As a region, Hampton Roads has worked hard to increase the number and quality of its medical facilities. The merger of Sentara and Tidewater Health Care sealed Sentara's position as the region's largest health care provider and forced it to rise to the challenge of offering excellent, efficient medical care. It has proven itself by attaining a ranking of 6th among all of the health networks in the nation, its third consecutive year in the top 10. Only two other health care systems have been named to the top 10 list for this many years. In addition, Sentara Norfolk General …

Characterization Of Hyporheic Zone Processes Of A Northern Prairie Stream, David B. Rush

Theses and Dissertations

A hyporheic zone occurs beneath and adjacent to streams where surface water and groundwater mix. This zone is known to be a reservoir for solutes and a habitat for interstitial organisms. Hyporheic zone boundaries in the Tongue River, North Dakota, were investigated through examination of the physicochemical and biological gradients present in the stream channel and bank sediments. The effects of cattle grazing at the streamside interface of the riparian zone were also examined at two locations to determine land use impacts on the hyporheic zone.

Electrical conductivity (EC) and ammonium gradients were observed beneath the stream channel via nests …

Air-Ground Temperature Exchange, William L. Schmidt

Theses and Dissertations

Most borehole paleoclimate studies have been based on the assumption that the exchange of temperature between the air and ground surface remains constant. However, secular changes in boundary-layer factors can generate anomalous ground temperatures. This dissertation is an investigation of factors that cause separation of air and ground temperatures on a seasonal to inter-annual time scale, including snow cover duration, latent energy of ground freezing, daily sunlight, precipitation, and vegetation.

Continual records of surface air and near-surface ground temperatures from five sites in North Dakota show similar trends in seasonal air-ground temperature separation. Statistical regressions of mean annual ground temperatures …
