Finding Aid for Hans M. Hansen Personal Papers, 1922-1967
No full textHans M. Hansen was born on May 30, 1883, in Trimbell, Wisconsin. When he was fourteen, he moved to Menomonie where he served an apprenticeship joining his employer, J.S. Govin, in 1904 to form the building and contracting firm of Govin and Hansen.
In 1912, Hansen joined the faculty at Stout teaching carpentry and cabinet making. He received his B.S. degree in Industrial Education from Stout in 1928 and his M.A. degree in Administration and Supervision with a minor in Industrial Education from the University of Minnesota in 1936.
Hansen retired in 1952 after 40 years of teaching at Stout. In 1965 he was honored by the university by having the Hansen-Keith-Milnes-Chinnock Hall named after him. Hansen died on December 29, 1967.This collection includes instruction materials from woodworking courses
The significance of the Hansen Ideal space frame
No full textKnown and unknown properties of Hansen Ideal coordinates are summarized. It is shown that the ideal space frame is a general and necessary component of basic celestial mechanics and astrodynamics, as well as of any theory of motion. A typical consequence is the intimate correlation of the Hansen frame with the Lagrange constraint within the method of the variation of the parameters. The use of observations in the ideal frame may allow conclusions on the intergalactic fundamental coordinate system

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Evaluating Asset-Pricing Models Using The Hansen-Jagannathan Bound: A Monte Carlo Investigation
No full textWe conduct Monte Carlo experiments to examine whether the bound proposed by Hansen and Jagannathan (1991) is a useful device for evaluating asset pricing models. Specifically, we use recently developed statistical tests, which are based on a 'distance' between the model and the Hansen-Jagannathan bound, to compute the rejection rates of true models. We provide finite-sample critical values for asset pricing models with time separable preferences, and show how they depend upon nuisance parameters—risk aversion and the rate of time preference. Further, we show that the finite-sample distribution of the test statistic associated with the risk-neutral case is extreme, in the sense that critical values based on this distribution will deliver type I errors no larger than intended—regardless of risk aversion or the rate of time preference. Extending the analysis to accommodate other preferences, we show that in the state non-separable case, the small-sample distributions of the test statistics are influenced significantly by the degree of intertemporal substitution, but not by attitudes toward risk. For habit formation preferences, the small-sample distributions are strongly influenced by the habit parameter. However, the maximal-size critical values for time-separable preferences are appropriate for habit formation as well as state non-separable preferences. We conclude that with these critical values the HJ bound is indeed a useful evaluation device. We then use the critical values to evaluate three asset pricing models using U.S. data. We find evidence against the time-separable model and mixed evidence on the remaining two models.
A tool for analysing depth resolution in potential-field inversion: application to the Neapolitan Volcanic Area
No full textA careful management of the data errors in potential field inversion is crucial for obtaining reliable information about the source distribution with respect to depth. The Depth Resolution Plot introduced by Fedi, Hansen and Paoletti provides a convenient tool for this analysis: it allows a computational/visual analysis of how much the depth resolution in a potential-field inversion problem is influenced by the way the problem is discretized and regularized. Here we present a variant of the Depth Resolution Plot, called Approx Depth Resolution Plot, which is better suited for large-scale problems, and we employ it to study the retrievable depth resolution in the inversion of the gravity field of the Neapolitan Volcanic Area
Data in Support of Predicting climate change impacts on poikilotherms using physiologically guided species abundance models
No full textFish catch and effort data for three species, along with lake characteristics, and watershed land cover. Additionally, there is mean July surface temperature derived from modeling and remotely sensed Secchi depth. Files include a Readme text file, and the data as a csv.Fish catch and effort data for three species caught in gill nets and trap nets between 1988 and 2019 as part of Minnesota Department of Natural Resources (MNDNR) fisheries surveys conducted during the summer and early fall are included from over 1,300 Minnesota lakes. The three fish species included are: bluegill (Lepomis marochirus) a warm-water adapted species, yellow perch (Perca flavescens) a cool-water adapted species, and cisco (Coregonus artedi) a cold-water adapted species. Additional data concerning lake characteristics and surrounding land cover were also included. Mean July lake surface temperature was calculated using simulated daily water temperatures. Watershed land use including agricultural, barren, forest, grass, shrub, urban, and wetland cover, was determined using the 2016 National Land Cover Database. Secchi, a measure of water clarity was calculated from remotely sensed Secchi depth courtesy of Max Glines. Lastly, lake area and maximum depth were obtained from MNDNR public databases.U.S. Geological Survey Midwest Climate Adaptation Science Center Grant No.G20AC00096Schliep, Erin M; North, Joshua S; Kundel, Holly; Custer, Christopher A; Ruzich, Jenna K; Hansen, Gretchen J A.
