Explaining Differences In One Teacher’S Instruction Across Multiple Tracked Fifth-Grade Classes, Corey Webel, Kimberly A. Conner, Christina Sheffel

Faculty Publications

In this article, we describe the case of “Keri,” a fifth-grade teacher who had completed an Elementary Mathematics Specialist (EMS) certification program. Drawn from a larger study investigating the knowledge, beliefs, and practices of EMSs, Keri's case was unique in that she was teaching mathematics to four classes in a departmentalized structure, where students were placed into different classes according to perceived mathematics ability. Observations from the larger study revealed that Keri's instructional practices did not align with her reported beliefs and knowledge. To explore this deviation, we conducted a case study where we observed Keri's instruction across multiple classes …

Evaluation Of Gpu Acceleration For Wrf–Sfire, Joshua Benz

Master's Projects

WRF–SFIRE is an open source, atmospheric–wildfire model that couples the WRF model with the level set fire spread model to simulate wildfires in real time. This model has many applications and more scientific questions can be asked and answered if the model can be run faster. Nvidia has put a lot of effort into easing the barrier of entry for accelerating applications with their tools to be run on GPUs. Various physical simulations have been successfully ported to utilize GPUs and have benefited from the speed increase. In this research, we take a look at WRF-SFIRE and try to use …

Energy Consumption Forecasting Using Machine Learning, Mahdi Mohammadigohari

Theses

Forecasting electricity demand and consumption accurately is critical to the optimal and costeffective operation system, providing a competitive advantage to companies. In working with seasonal data and external variables, the traditional time-series forecasting methods cannot be applied to electricity consumption data. In energy planning for a generating company, accurate power forecasting for the electrical consumption prediction, as a technique, to understand and predict the market electricity demand is of paramount importance. Their power production can be adjusted accordingly in a deregulated market. As data type is seasonal, Persistence Models (Naïve Models), Seasonal AutoRegressive Integrated Moving Averages with eXogenous regressors (SARIMAX), …

All-Sky Search For Short Gravitational-Wave Bursts In The Third Advanced Ligo And Advanced Virgo Run, R. Abbott, T. Abbott, F. Acernese, K. Ackley, Teviet Creighton, Mario C. Diaz, Francisco Llamas, Soma Mukherjee, Volker Quetschke, Wenhui Wang

Physics & Astronomy Faculty Publications

This paper presents the results of a search for generic short-duration gravitational-wave transients in data from the third observing run of Advanced LIGO and Advanced Virgo. Transients with durations of milliseconds to a few seconds in the 24–4096 Hz frequency band are targeted by the search, with no assumptions made regarding the incoming signal direction, polarization, or morphology. Gravitational waves from compact binary coalescences that have been identified by other targeted analyses are detected, but no statistically significant evidence for other gravitational wave bursts is found. Sensitivities to a variety of signals are presented. These include updated upper limits on …

Workflow Critical Path: A Data-Oriented Critical Path Metric For Holistic Hpc Workflows, Daniel D. Nguyen, Karen L. Karavanic

Computer Science Faculty Publications and Presentations

Current trends in HPC, such as the push to exascale, convergence with Big Data, and growing complexity of HPC applications, have created gaps that traditional performance tools do not cover. One example is Holistic HPC Workflows — HPC workflows comprising multiple codes, paradigms, or platforms that are not developed using a workflow management system. To diagnose the performance of these applications, we define a new metric called Workflow Critical Path (WCP), a data-oriented metric for Holistic HPC Workflows. WCP constructs graphs that span across the workflow codes and platforms, using data states as vertices and data mutations as edges. …

Explaining Deep Learning Models For Tabular Data Using Layer-Wise Relevance Propagation, Ihsan Ullah, Andre Rios, Vaibhov Gala, Susan Mckeever

Articles

Trust and credibility in machine learning models are bolstered by the ability of a model to explain its decisions. While explainability of deep learning models is a well-known challenge, a further challenge is clarity of the explanation itself for relevant stakeholders of the model. Layer-wise Relevance Propagation (LRP), an established explainability technique developed for deep models in computer vision, provides intuitive human-readable heat maps of input images. We present the novel application of LRP with tabular datasets containing mixed data (categorical and numerical) using a deep neural network (1D-CNN), for Credit Card Fraud detection and Telecom Customer Churn prediction use …

Stubble Height Effects On Limpograss Pasture Characteristics And Performance Of Beef Heifers, Y. C. Newman, Lynn E. Sollenberger, W. E. Kunkle, D. B. Bates, C. G. Chambliss, A. M. Fox

IGC Proceedings (1977-2023)

Limpograss (Hemarthria altissima [Poir.] Stapf. & C.E. Hubb.) is a C₄ species used in Florida beef production systems because of its cool-season growth, persistence on poorly drained soils, and high yield and digestibility. Animal performance on limpograss pastures, however, has been limited by low herbage crude protein (CP). This study evaluated the effect of canopy height of limpograss pastures and N supplementation of grazing cattle on sward characteristics and weight gain and blood urea N (BUN) concentration of yearling beef heifers. Under continuous stocking, six treatments were imposed that included all combinations of three stubble heights (20, 40, …

Decreasing Incomes Increase Selfishness, Nickolas Gagnon, Riccardo D. Saulle, Henrik W. Zaunbrecher

Fondazione Eni Enrico Mattei Working Papers

We use a controlled laboratory experiment to study the causal impact of income de-creases within a time period on redistribution decisions at the end of that period, in an environment where we keep fixed the sum of incomes over the period. First, we inves-tigate the effect of a negative income trend (intra-personal decrease), which means a decreasing income compared to one’s recent past. Second, we investigate the effect of a negative income trend relative to the income trend of another person (inter-personal decrease). If intra-personal or inter-personal decreases create dissatisfaction for an individual, that person may become more selfish to …

Seedemu: The Seed Internet Emulator, Honghao Zeng

Theses - ALL

I studied and experimented with the idea of building an emulator for the Internet. While there are various already available options for such a task, none of them takes the emulation of the entire Internet as an important feature in mind. Those emulators and simulators can handle small-scale networks pretty well, but lacks the ability to handle large-size networks, mainly due to:

- Not being able to run many nodes, or requires very powerful hardware to do so,- Lacks convenient ways to build a large emulation, and - Lacks reusability: once something is built, it is very hard to re-use …

The Role Of Rab11 Or Rab8-Associated Membranes During Kupffer's Vesicle (Kv) Lumen Formation In Vivo, Eric Ingram

Theses - ALL

In early embryonic development, cells undergo a series of shape changes called tissue morphogenesis by which tissues develop into an organ. One mechanism that is potentially vital to tissue morphogenesis is abscission, the cleavage of the cytokinetic bridge. Our lab has proposed that abscission is required for tissue morphogenesis in vivo, specifically in the zebrafish left-right organizer, Kupffer's vesicle (KV). The Hehnly Lab's testable model for KV morphogenesis is that a population of cells, some in cytokinesis, group together in a pre-rosette structure and then self-assemble to form a rosette-structure where cells orient their cytokinetic bridges toward the rosette center. …

A Brief Treatise On Bayesian Inverse Regression., Debashis Chatterjee Dr.

Doctoral Theses

Inverse problems, where in a broad sense the task is to learn from the noisy response about some unknown function, usually represented as the argument of some known functional form, has received wide attention in the general scientific disciplines. However, apart from the class of traditional inverse problems, there exists another class of inverse problems, which qualify as more authentic class of inverse problems, but unfortunately did not receive as much attention.In a nutshell, the other class of inverse problems can be described as the problem of predicting the covariates corresponding to given responses and the rest of the data. …

High-Resolution Cryo-Electron Microscopy Structure Of Photosystem Ii From The Mesophilic Cyanobacterium, Synechocystis Sp. Pcc 6803, Christopher J. Gisriel, Jimin Wang, Jinchan Liu, David A. Flesher, Krystle M. Reiss, Hao-Li Huang, Ke R. Yang, William H. Armstrong, M. R. Gunner, Victor S. Batista, Richard J. Debus, Gary W. Brudvig

Publications and Research

Photosystem II (PSII) enables global-scale, light-driven water oxidation. Genetic manipulation of PSII from the mesophilic cyanobacterium Synechocystis sp. PCC 6803 has provided insights into the mechanism of water oxidation; however, the lack of a highresolution structure of oxygen-evolving PSII from this organism has limited the interpretation of biophysical data to models based on structures of thermophilic cyanobacterial PSII. Here, we report the cryo-electron microscopy structure of PSII from Synechocystis sp. PCC 6803 at 1.93-Å resolution. A number of differences are observed relative to thermophilic PSII structures, including the following: the extrinsic subunit PsbQ is maintained, the C terminus of the …

A Variable Stiffness Energy Dissipation Device For Vibration Control Of Steel Frames, Tie Zheng

Dissertations - ALL

Structures without energy dissipation devices rely primarily on plastic or inelastic deformations to dissipate energy from earthquakes. As a result, the amount of inelastic deformations and damage level will increase as the earthquake severity increases. However, structures equipped with energy dissipation devices are expected to experience less inelastic deformations and so their safety and integrity can be better preserved.In this research, a new device called the variable stiffness energy dissipation device is conceptualized and numerically studied. Using nonlinear time history analysis, results are obtained to illustrate the effectiveness of the proposed device in enhancing the seismic performance of shear and …

Investigation Of Lithium-Ion Battery Electrode Fabrication Through A Predictive Particle-Scale Model Validated By Experiments, Mojdeh Nikpour

Theses and Dissertations

Next-generation batteries with improved microstructure and performance are on their way to meet the market demands for high-energy and power storage systems. Among different types of batteries, Li-ion batteries remain the best choice for their high energy density and long lifetime. There is a constant but slow improvement in Li-ion batteries by developing new materials and fabrication techniques. However, further improvements are still needed to meet government and industry goals for cost, cycling performance, and cell lifetime. A fundamental understanding of particle-level interactions can shed light on designing new porous electrodes for high-performance batteries. This is a complex problem because …

Predicting Drug-Induced Liver Injury With Artificial Intelligence, Ting Li

Theses and Dissertations

Drug-induced liver injury (DILI) is an undesirable side effect to the liver caused by the common use of drugs, which is of great concern to the patients, physicians, the pharmaceutical industry, and government regulators. The current animal testing models do not present reliable results on the human DILI risk prediction during the preclinical phase. Therefore, there is an urgent need to find alternative methods to improve the human DILI risk prediction during the early stage of development. Utilizing the accumulated high-throughput transcriptomics profiles from L1000, we constructed an 8-layer deep neural network for human DILI prediction based on the largest …

Detecting Supraglacial Debris Thickness With Gpr Under Suboptimal Conditions, Alexandra Giese, Steven Arcone, Robert Hawley, Gabriel Lewis, Patrick Wagnon

Dartmouth Scholarship

The thickness of a supraglacial layer is critical to the magnitude and time frame of glacier melt. Field-based, short pulse, ground-penetrating radar (GPR) has successfully measured debris thickness during a glacier's melt season, when there is a strong return from the ice-debris interface, but profiling with GPR in the absence of a highly reflective ice interface has not been explored. We investigated the performance of 960 MHz signals over 2 km of transects on Changri Nup Glacier, Nepal, during the post-monsoon. We also performed laboratory experiments to interpret the field data and investigate electromagnetic wave propagation into dry rocky debris. …

Distribution And Characterization Of Rhyolites Of The Strawberry Volcanics -- Evolution Of A Major Rhyolite Field Associated With Columbia River Basalt Magmatism, Eastern Oregon, Usa, Chanel Leigh Dvorak

Dissertations and Theses

The Strawberry Rhyolites constitute a significant rhyolite field among the largest in Oregon. Aerial coverage of approximately 386 km² and an overall estimated volume of ~67 km³ using a median thickness for each unit. On the other hand, the total volume could be greater than 100 km³ if greater thicknesses apply. The Strawberry Rhyolites, a largely unknown mid-Miocene silicic volcanic rocks, crop out amongst voluminous flood basalt flows of the Columbia River Basalt Group (CRBG) in eastern Oregon. The eruptive activity of the Strawberry Rhyolites is currently constrained to span a period of about 2 million years, …

Developing Novel Molecular Detection Techniques For Hemlock Woolly Adelgid (Adelges Tsugae), Meg Sanders

Masters Theses

Hemlock forests in eastern North America face a deadly threat: the invasive insect, hemlock woolly adelgid (HWA), Adelges tsugae. Early detection of this pest remains a key focus for management groups to ensure rapid response to control and stop the spread of HWA. In Chapter II, our goals were to develop an affordable, easy-to-use trap that is compatible with airborne eDNA sampling techniques and assess its efficiency as a monitoring tool for HWA. We tested three potential trap designs (i.e., passive trap, funnel trap, and motorized trap) against a standard sticky trap. Our passive, funnel, and motorized traps estimated …

A Tale Of Three Resources: The Influence Of Multiple Resources On Plant-Herbivore Interactions, Neha Mohan Babu

Dissertations - ALL

Although studies indicate that plant growth can be co-limited by multiple resources, particularly water, nitrogen (N), and phosphorus (P), the role of co-limiting resources in driving plant-herbivore interactions remains poorly understood. Evidence indicates that the resources that limit plant and herbivore growth may differ which likely influences trophic interactions. In this dissertation, I explored how multiple resource limitation of plants affects herbivore abundance, herbivore impact on plant biomass, and plant traits, using both theoretical and empirical methods. As none of the existing hypotheses account for the effects of multiple resource limitation, I developed a novel theoretical model to predict the …

A Portrait Of Postsecondary Stem Teaching: Examining The Roles Of Organizational Climate And Professional Identity, Sule Aksoy

Dissertations - ALL

Many empirical studies on the factors associated with the use of evidence-based instructional practices have examined the individual and contextual characteristics. However, little attention has been afforded to the role of context and practice on teacher identity. This dissertation consists of three-article style papers that examine the relationship between contextual factors, teacher identity, and instructional practices to fill this gap in the literature. Chapter 1 provides a deep understanding of organizational climate in STEM departments concerning teaching practices. Significant differences in organizational factors such as leadership, resources, and respect for teaching were found between graduate instructors and the faculty. Similarly, …

Buckling Patterns And Mechanics Of Thin Interfacial Polymer Films, Monica M. Ripp

Dissertations - ALL

Thin elastic solids are easily deformed and will readily collapse into complex buckling modes. They can also transition between distinct buckling modes when the confining forces evolve over time, forming a variety of robust and striking patterns. Here we explore how thin interfacial films and the buckling modes they present couple with evolving macroscopic forces and how multi-scale features of the systems give rise to patterns.

In the indentation of a circular film floating on a liquid bath three buckling modes arise: wrinkling, crumpling, and folding. This work shows that striking transitions between these states accompany four regimes in the …

Exploration Of Carbon-Oxygen And Carbon-Nitrogen Bond Formation Utilizing Trichloroacetimidates And Investigations Of New Reactions Mediated By Oxoammonium Salts, Rowan Meador

Dissertations - ALL

Mono-O-alkylated 1,1′-bi-2-naphthols (BINOLs) are often used as the source of chirality for catalysts or ligand systems that are employed in asymmetric organic transformations. However, these BINOLs can be hard to synthesize. The O-alkylation of BINOL can be accomplished with primary and secondary alkyl halides or under Mitsunobu conditions, the yields of these alkylations with tertiary halides or alcohols are very low. A new protocol was developed utilizing trichloroacetamide electrophiles to install bulky groups onto one of the phenolic oxygens. Trichloroacetimidates are also shown to be useful reactions for the synthesis of esters. These reagents proceeded through a symbiotic activation pathway. …
