A Generalized Data Conversion System, Kevan Morgan
A Generalized Data Conversion System, Kevan Morgan
Undergraduate Honors Capstone Projects
To assist in the processing of data files collected by the Space Dynamics Laboratory at Utah State University, the software project GENDACS has been completed. GENDACS, acronym for A Generalized Data Conversion System, will contribute to its research program.
Data are collected from various sensory instruments by the Computer Data Acquisition System. The instrument readings are brought in, tagged with the time they were taken, and stored on an optical disk in a compact, binary (non-ASCII) format. GENDACS is designed so that the program can read in such files, sort out the data, and convert them into a new ASCII …
Probable Maximum Flood Estimation In Northern Utah, Khin Maung Win
Probable Maximum Flood Estimation In Northern Utah, Khin Maung Win
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The probable maximum flood (PMF) is used for the xxi assessment of maximum flood potentials in spillway sizing of new dams and in evaluating the adequacy of existing hydrologic structures. Determination of the PMF begins with the estimation of the probable maximum precipitation (PMP) for a particular dam site. Selecting hydrologic methods and assumptions for converting PMP to PMF, which are most appropriate for Utah conditions, is important to meet current inflow design flood (IDF) safety standards.
The objectives of this study were (a) to demonstrate a maximization approach to PMF determination, (b) to evaluate effects of basin characteristics and …
A Mechanistic Approach To Modeling Habitat Needs Of Drift-Feeding Salmonids, R. Craig Addley
A Mechanistic Approach To Modeling Habitat Needs Of Drift-Feeding Salmonids, R. Craig Addley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A mechanistic model is developed to determine the habitat needs of drift-feeding stream salmonids from the direct cause-and-effect relationships of environmental and physiological variables on net energy intake (NEI). The model determines NEI by subtracting energy costs (basal metabolism, swimming cost, digestion cost) and losses (egestion and excretion) from the gross energy intake obtained as a result of simulated prey capture. The prey capture portion of the model utilizes components of the predation model of C.S. Holling and the prey capture model of N.F. Hughes and L.M. Dill to determine the rate of prey capture (gross energy intake) as a …
Analysis Of Cutthroat Flume Discharge Ratings, Liyan Ren
Analysis Of Cutthroat Flume Discharge Ratings, Liyan Ren
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Sixteeen sets of original laboratory data collected by many investigators for various Cutthroat flume sizes are thoroughly reviewed and organized. Best-fit discharge parameters are obtained by performing the free-flow analysis and the submerged-flow analysis. Then, the transition submergence can be calculated. Afterwards, the unified free-flow and submerged-flow discharge parameters are developed for each flume size in order to generalize the calibrations for Cutthroat flumes. This is a very tedious process requiring a trial-and-error approach. Finally, comparisons are made of the measured laboratory discharges with the predicted discharges for both free flow and submerged flow using both the best-fit and the …
Jet Velocity Dissipation And Modelling With Aeration, Stephen J. Schlenker
Jet Velocity Dissipation And Modelling With Aeration, Stephen J. Schlenker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effects of natural aeration and fall height upon velocity dissipation and modelling were studied. Underwater velocities and void ratios (proportion of air volume to total volume) were measured along the jet centerline at various depths in the receiving pool under 1- and 2-inch diameter vertical circular free-falling jets. Maximum air bubble penetration depths were also measured. In the tests, the nozzle velocities were designed so that the two differently sized models would have equivalent Froude numbers for direct comparison of respective underwater parameters. Air entrainment-the natural development of air bubbles within a pool receiving a free-falling jet-causes voids to …
