Investigating Rapid Concrete Repair Materials And Admixtures, Ivan Quezada

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation presents a literature review of the state-of-practice for the use of IC in concrete mixtures and how structural engineers and construction engineers can adapt IC to their present and future work. Current high early strength concrete mixtures have natural cracking and shrinkage problems due to the high content of cementitious material or their chemical components. Using IC allows for early strength, enhanced durability, reduced shrinkage and a better curing by providing water that can be absorbed by the cement past after the final set. Rapid hydration and high early strength Portland cement and calcium sulfoaluminate (CSA) concretes are …

Droplet Impact Onto Super-Hydrophobic Surfaces And Determining The Response To Heat And Light Of Terrestrial Cyanobacteria, Benjamin B. Lovett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis examines droplets striking water repelling surfaces as well as the movement of a soil based bacteria under various light and heat conditions. Droplet impact studies have shown that introducing a macroscopic feature to a water repelling surface can reduce the amount of time that droplet is in contact with the surface. By manipulating water droplets to impact different sized needles at varying speeds, we present how a needle can induce a similar reduction in the residence time of the droplet to more widely studied features. Results show the spreading and lift-off characteristics of the droplet are dependent on …

Application Of Winslamm To Evaluate The Effect Of Green Infrastructure Implementation In Northern Utah, Rosa A. Fernández Velásquez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study provides an evaluation of the performance of the WinSLAMM model in two cities of northern Utah, a region in which it has not been validated to date. Runoff volumes for a series of events from 2015 to 2017 were calculated for six study areas. These results were compared to model outputs to evaluate the prediction accuracy. The model performed poorly when default parameters where used, as expected. Thus, the calibration of runoff coefficient was done with local data. Total suspended solids (TSS), total phosphorus (TP) and total dissolved phosphorus (TDP) were also evaluated and calibrations were developed. The …

Estimating Actual Evapotranspiration From Stony-Soils In Montane Ecosystems, Kshitij Parajuli, Scott B. Jones, David G. Tarboton, Gerald N. Flerchinger, Lawrence E. Hipps, L. Niel Allen, Mark S. Seyfried

Plants, Soils, and Climate Faculty Publications

Quantification of evapotranspiration (ET) is crucial for understanding the water balance and for efficient water resources planning. Agricultural settings have received most attention regarding ET measurements while less knowledge is available for actual ET (ET_A) in natural ecosystems, many of which have soils containing significant amounts of stones. This study is focused on modelling ET_A from stony soil, particularly in montane ecosystems where we estimate the contribution of stone content on water retention properties in soil. We employed a numerical model (HYDRUS-1D) to simulate ET_A in natural settings in northern Utah and southern Idaho during the …

Effect Of Meter Orientation Downstream Of A Short Radius Elbow On Electromagnetic Flow Meters, Jared C. Justensen, Steven L. Barfuss, Michael C. Johnson, Thomas E. Meacham

Civil and Environmental Engineering Faculty Publications

Electromagnetic flow meters (known as magnetic flow meters) are a widely used type of flow meter. This study examines the performance of magnetic flow meters when the electrodes in the meter are positioned at two different orientations: electrodes parallel with the plane of an upstream 90° short radius elbow and electrodes perpendicular to the plane of an upstream 90° short radius elbow. Four different meters from four different manufacturers were included in the study in which a baseline straight pipe test was first performed using more than 50 diameters of straight pipe upstream of each meter. The four meters were …

Geoflood: Large-Scale Flood Inundation Mapping Based On High-Resolution Terrain Analysis, Xing Zheng, David R. Maidment, David G. Tarboton, Yan Y. Liu, Paola Passalacqua

Civil and Environmental Engineering Faculty Publications

Recent floods from intense storms in the southern United States and the unusually active 2017 Atlantic hurricane season have highlighted the need for real‐time flood inundation mapping using high‐resolution topography. High‐resolution topographic data derived from lidar technology reveal unprecedented topographic details and are increasingly available, providing extremely valuable information for improving inundation mapping accuracy. The enrichment of terrain details from these data sets, however, also brings challenges to the application of many classic approaches designed for lower‐resolution data. Advanced methods need to be developed to better use lidar‐derived terrain data for inundation mapping. We present a new workflow, GeoFlood, for …

Hidden Curriculum Awareness: A Comparison Of Engineering Faculty, Graduate Students, And Undergraduates, Idalis Villanueva, Marialuisa Di Stefano, Laura Gelles, Katherine Youmans

Engineering Education Faculty Publications

In order for an engineering academic body (e.g., facultyand students) to navigate their surroundings, they must first become aware of the hidden curriculum around them. Hidden curriculum represents how particular assumptions, values, attitudes, and beliefs about schooling manifests in practice. When understood, these types of lessons or messages allow students, faculty, and staff to more easily navigate the academic and socio-political customs needed for success.

As part of a larger study, a total of 224 participants across 57 engineering programs in the United States and Latin America were asked to comment on a survey that asked respondents about the expectations …

Assessing The Limitations Of Effective Number Of Samples For Finding The Uncertainty Of The Mean Of Correlated Data, Barton L. Smith, Douglas R. Neal, Mark Feero, Geordie Richards

Mechanical and Aerospace Engineering Faculty Publications

The efficacy of recent and classical theories on the uncertainty of the mean of correlated data have been investigated. A variety of very large data sets make it possible to show that, under circumstances that are often too expensive to achieve, the integral time scale can be used to determine the effective number of independent samples, and therefore the uncertainty of the mean. To do so, the data set must be sufficiently large that it may be divided into many records, each of which is many integral time scales long. In this circumstance, all lags of the autocorrelation should be …

Environmental Water Transactions In The Colorado River Basin: A Closer Look, Leon Szeptycki, David Pilz, Rachel O'Connor, Beatrice Gordon

All In-stream Flows Material

Over the last 30 years, the voluntary transfer of water and water rights for environmental uses has become a recognized strategy for restoring streamflow in the Western United States.¹ Historically, taking water out of a stream was a legally required element of an appropriative water right. Water rights holders who left all or a portion of their right instream to enhance fish populations, riparian habitat or recreation, risked forfeiture or diminishment of their water right. Beginning in the 1980’s, state laws began to recognize both the appropriation of new water rights for instream use and to allow the transfer …

Trident: Comprehensive Choke Error Mitigation In Ntc Systems, Aatreyi Bal, Sanghamitra Roy, Koushik Chakraborty

Electrical and Computer Engineering Faculty Publications

Near threshold computing (NTC) systems have been inherently plagued with heightened process variation (PV) sensitivity. Choke points are an intriguing manifestation of this PV sensitivity. In this paper, we explore the probability of minimum timing violations, caused by choke points, in an NTC system, and their nontrivial impacts on the system reliability. We show that conventional timing error mitigation techniques are inefficient in tackling choke point-induced minimum timing violations. Consequently, we propose a comprehensive error mitigation technique, Trident, to tackle choke points at NTC. Trident offers a 1.37 × performance improvement and a 1.11 × energy-efficiency gain over Razor at …
