The Costs Of A Free And Public Education: An Analysis Of A School District's Student Fees, Jacob D. Skousen, Ellianna Rodriguez
BYU Education & Law Journal
Since the late 1800s U.S. states have provided a “centrally administered organization of public schools, overseen by a state superintendent or department of education and financed by state income tax revenues in addition to local taxes.” States have governed a system of public schools through the states’ constitutions. Each state’s constitution has a statement identifying the state as being responsible to provide its citizenry with a public education and in the majority of states’ constitutions there is further clarification noting that this education is provided free of charge. An example of this statement can be found in Nevada’s State Constitution, …

How Failures Cascade In Software Systems, Barbara W. Chamberlin
How Failures Cascade In Software Systems, Barbara W. Chamberlin
Theses and Dissertations
Cascading failures involve a failure in one system component that triggers failures in successive system components, potentially leading to system wide failures. While frequently used fault tolerant techniques can reduce the severity and the frequency of such failures, they continue to occur in practice. To better understand how failures cascade, we have conducted a qualitative analysis of 55 cascading failures, described in 26 publicly available incident reports. Through this analysis we have identified 16 types of cascading mechanisms (organized into eight categories) that capture the nature of the system interactions that contribute to cascading failures. We also discuss three themes …

A New Method And Python Toolkit For General Access To Spatiotemporal N-Dimensional Raster Data, Riley Chad Hales
Theses and Dissertations
Scientific datasets from global-scale scientific models and remote sensing instruments are becoming available at greater spatial and temporal resolutions with shorter lag times. These data are frequently gridded measurements spanning two or three spatial dimensions, the time dimension, and often several data dimensions which vary by the specific dataset. These data are useful in many modeling and analysis applications across the geosciences. Unlike vector spatial datasets, raster spatial datasets lack widely adopted conventions in file formats, data organization, and dissemination mechanisms. Raster datasets are often saved using the Network Common Data Format (NetCDF), Gridded Binary (GRIB), Hierarchical Data Format (HDF), …

Compiler-Based Tools To Aid In Data Transfer Optimization And On-Chip Debug Of Heterogeneous Compute Systems, Matthew B. Ashcraft
Theses and Dissertations
First, we present techniques to efficiently schedule data transfers through compiler analyses. Compared to transferring data immediately before and after the kernel executes, our scheduling results in orders of magnitude improvements in execution time, number of data transfers, and number of bytes transferred. Second, we demonstrate techniques to provide on-chip debugging for heterogeneous systems through recording execution on the software in addition to debugging circuitry in the hardware, and provide a temporal correlation between the hardware and software traces through synchronization. This allows us to follow debug data between the hardware and software trace buffers. Due to the added cost …

Application Of Ground-Based Lidar And Gap Intercept Measurements To Quantify A Shrub Configuration Metric Within Greater Sage-Grouse Nesting Habitat, Khodabakhsh Zabihi, Kenneth L. Driese, Ginger B. Paige, Ann L. Hild
Western North American Naturalist
Vegetation composition (i.e., relative proportion of species) and configuration (i.e., horizontal and vertical arrangement of the plant components) in sagebrush-steppe ecosystems are fundamental determinants of the suitability of nesting habitat for Greater Sage-Grouse (Centrocercus urophasianus). The spatial arrangement of shrub and herbaceous canopy cover conceals Greater Sage-Grouse from predators and protects the nest from natural hazards, and gaps in vegetative cover provide escape routes for hens. Most sage-grouse habitat studies quantify vegetation composition, but few quantify habitat configuration at fine scales. We used ground-based lidar (light detection and ranging) data from Greater Sage-Grouse nesting habitat to test the …

Of Fire, Mammals, And Rain: Mechanisms Of Plant Invasions, Tara Boyce Bishop
Theses and Dissertations
Biological invasions are driving environmental state changes on a global scale. Exotic plant species must be successful at passing several abiotic and biotic filters to establish and disrupt the native plant community assembly. Understanding where exotic plants are on a regional scale and being able to characterize how exotic plants are generally interacting with their environment is crucial information for exotic species management (chapter 1). In the western United States human-related activities are augmenting the spread of exotic plant species by increasing the ignitions of wildfire. Wildfire can lead to nutrient pulses through the removal of intact native communities and …

Increasing The Accuracy Of Molecular Biomarkers Via Evidence-Based Algorithm Selection, Stephen R. Piccolo
Journal of Undergraduate Research
In making medical decisions, physicians need observable criteria that they can use to make accurate diagnoses, determine optimal treatments, and estimate a patient’s prognosis. The promise of precision medicine is that molecular-level observations can more accurately predict such information than traditional observations. I worked with undergraduate students at Brigham Young University to develop ways to improve the accuracy of such predictions by optimizing computer algorithms to handle the complexity of large, molecular data sets.

Netlight: Cloud Baked Indirect Illumination, Nathan Andrew Zabriskie
Netlight: Cloud Baked Indirect Illumination, Nathan Andrew Zabriskie
Theses and Dissertations
Indirect lighting drastically increases the realism of rendered scenes but it has traditionally been very expensive to calculate. This has long precluded its use in real-time rendering applications such as video games which have mere milliseconds to respond to user input and produce a final image. As hardware power continues to increase, however, some recently developed algorithms have started to bring real-time indirect lighting closer to reality. Of specific interest to this paper, cloud-based rendering systems add indirect lighting to real-time scenes by splitting the rendering pipeline between a server and one or more connected clients. However, thus far they …
