Modeling Ash Deposit Growth Rates For A Wide Range Of Solid Fuels In A 100 Kw Combustor, Seyedhassan Fakourian, Zachary Mcallister, Andrew R. Fry, Yueming Wang, Xiaolong Li, Jost O.L. Wendt, Jinze Dai

Faculty Publications

This work details a model for evaluating the relative ash deposition propensity of various solid fuels without the complicated spatial considerations included in CFD modeling. Four deposition mechanisms are included, namely: inertial impaction, thermophoresis, condensation, and eddy impaction. This model has been validated and shown to effectively predict ash deposit rates for a wide range of solid fuels including coal, biomass, and their blends, burned in a 100 kW rated downflow combustor. Specifically, this work presents and compares two separate models for the sticking efficiency of impacting ash particles on a coupon surface: the melt fraction stickiness …

An Automated Tool For Comparing Phonetic Transcriptions, Dallin J. Bailey, Marisha Speights Atkins, Ishaan Mishra, Sicheng Li, Yaoxuan Luan, Cheryl Seals

Faculty Publications

Many computerized tools for comparing phonetic transcriptions have been proposed and shared in the past; however, previous tools are relatively difficult to access and incorporate into clinical and research practice, or require users to learn additional phonetic symbol systems. The purpose of this project was to develop and test a readily available web-based application for quantitatively comparing phonetic transcriptions that are input using International Phonetic Alphabet (IPA) symbols. A web-based computer application was developed to allow for IPA phonetic transcription comparison. A point-and-click keyboard was developed to provide support for character input of the full IPA, as well as most …

Examination Of Eating Disorder Risk Among University Marching Band Artists, Nancy A. Uriegas, Dawn M. Emerson, Allison B. Smith, Melani R. Kelly, Toni M. Torres-Mcgehee

Faculty Publications

BACKGROUND: Marching band artists are a physically active population, composed of approximately 27,000 people in the United States. University marching band artists face many of the same physically active demands and mental stressors as student athletes, potentially predisposing them to injury, illness, and risk for eating disorders (EDs). The purpose of this study was to examine ED risk across sex in university marching band artists, and to determine the type of risk based on the Eating Disorder Inventory-3 (EDI-3) and Eating Disorder Inventory-3 Symptom Check List (EDI-3 SC). A secondary aim examined marching band artists and pathogenic weight control behavior …

Effects Of Background Noise On Speech And Language In Young Adults, Tyson G. Harmon, Christopher Dromey, Brenna Nelson, Kacy Chapman

Faculty Publications

Purpose: To investigate how different types of background noise that differ in their level of linguistic content affect speech acoustics, speech fluency, and language production for young adult speakers when performing a monologue discourse task.

Method: Forty young adults monologued by responding to open ended questions in a silent baseline and five background noise conditions (debate, movie dialogue, contemporary music, classical music, pink noise). Measures related to speech acoustics (intensity and frequency), speech fluency (speech rate, pausing, and disfluencies), and language production (lexical, morphosyntactic, and macro-linguistic structure) were analyzed and compared across conditions. Participants also reported on which conditions they …

Impact Damage Ascertainment In Composite Plates Using In-Situ Acoustic Emission Signal Signature Identification, Robin James, Roshan Prakash Joseph, Victor Giurgiutiu

Faculty Publications

Barely visible impact damage (BVID) due to low velocity impact events in composite aircraft structures are becoming prevalent. BVID can have an adverse effect on the strength and safety of the structure. During aircraft inspections it can be extremely difficult to visually detect BVID. Moreover, it is also a challenge to ascertain if the BVID has in-fact caused internal damage to the structure or not. This paper describes a method to ascertain whether or not internal damage happened during the impact event by analyzing the high-frequency information contained in the recorded acoustic emission signal signature. Multiple 2 mm quasi-isotropic carbon …

The MiniBooNE experiment at Fermilab reports a total excess of 638.0 +/- 52.1(stat) +/- 122.2(syst) electronlike events from a data sample corresponding to 18.75 x 10(20) protons-on-target in neutrino mode, which is a 46% increase in the data sample with respect to previously published results and 11.27 x 10(20) protons-on-target in antineutrino mode. The overall significance of the excess, 4.8 sigma, is limited by systematic uncertainties, assumed to be Gaussian, as the statistical significance of the excess is 12.2 sigma. The additional statistics allow several studies to address questions on the source of the excess. First, we provide two-dimensional plots …

Subtropical systems experience occasional severe floods, dramatically altering the phytoplankton community structure, in response to changes in salinity, nutrients, and light. This study examined the effects of a 1:100 year summer flood on the phytoplankton community in an Australian subtropical bay – Moreton Bay – over 48 weeks, from January to December 2011. Immediately after maximum flood levels were reached on the rivers flowing into the bay, the lowest salinity, and highest turbidity values, in more than a decade, were measured in the Bay and the areal extent of the flood-related parameters was also far greater than previous flood events. …

The Epigenetics Of Gametes And Early Embryos And Potential Long-Range Consequences In Livestock Species—Filling In The Picture With Epigenomic Analyses, Linkai Zhu, Sadie L. Marjani, Zongliang Jiang

Faculty Publications

The epigenome is dynamic and forged by epigenetic mechanisms, such as DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA species. Increasing lines of evidence support the concept that certain acquired traits are derived from environmental exposure during early embryonic and fetal development, i.e., fetal programming, and can even be “memorized” in the germline as epigenetic information and transmitted to future generations. Advances in technology are now driving the global profiling and precise editing of germline and embryonic epigenomes, thereby improving our understanding of epigenetic regulation and inheritance. These achievements open new avenues for the development of technologies or potential …

Faculty Publications

Background: The clinical predictors and biological mechanisms for localized prostate cancer (PCa) outcomes remain mostly unknown. We aim to evaluate the role of serum immune-checkpoint-related (ICK) proteins and genetic variations in predicting outcomes of localized PCa. Methods: We profiled the serum levels of 14 ICK-related proteins (BTLA, GITR, HVEM, IDO, LAG-3, PD-1, PD-L1, PD-L2, Tim-3, CD28, CD80, 4-1BB, CD27, and CTLA-4) in 190 patients with localized PCa. The genotypes of 97 single nucleotide polymorphisms (SNPs) from 19 ICK-related genes were analyzed in an extended population (N = 1762). Meta-data from ArrayExpress and TCGA was employed to validate and to probe …

A State-Dependent Approximation Method For Estimating Truck Queue Length At Marine Terminals, Wenrui Qu, Tao Tao, Bo Xie, Yi Qi

Faculty Publications

As international trade and freight volumes increase, there is a growing port congestion problem, leading to the long truck queues at US marine terminal gates. To address this problem, some countermeasures have been proposed and implemented for reducing truck queue length at marine terminals. To assess the effectiveness of these countermeasures, a method for accurately estimating terminal gate truck queue length is needed. This study developed a new method, named the state-dependent approximation method, for estimating the truck queue length at marine terminals. Based on the simulation of the truck queuing system, it was found that it takes several hours …

Physical Transport Processes That Affect The Distribution Of Oil In The Gulf Of Mexico Observations And Modeling, Michel Boufadel, Annalisa Bracco, Eric P. Chassignet, Shuyi S.

Socolofsky, David Halpern, John G. Shepherd

Faculty Publications

Physical transport processes such as the circulation and mixing of waters largely determine the spatial distribution of materials in the ocean. They also establish the physical environment within which biogeochemical and other processes transform materials, including naturally occurring nutrients and human-made contaminants that may sustain or harm the region’s living resources. Thus, understanding and modeling the transport and distribution of materials provides a crucial substrate for determining the effects of biological, geological, and chemical processes. The wide range of scales in which these physical processes operate includes microscale droplets and bubbles; small-scale turbulence in buoyant plumes and the near-surface “mixed” …

Evidence-Based Use Of Cognitive Testing For Academic Interventions: A Critical Appraisal Of Meta-Analytic Methodologies, Scott L. Decker, Jessica C. Luedke

Faculty Publications

Research suggests Specific Learning Disabilities (SLD) are directly linked to specific neurocognitive deficits that result in unexpected learning delays in academic domains for children in schools. However, meta-analytic studies have failed to find supporting evidence for using neurocognitive tests and, consequently, have discouraged their inclusion in SLD identification policies. The current study critically reviews meta-analytic findings and the methodological validity of over 200 research studies used in previous meta-analytic studies to estimate the causal effect of neurocognitive tests on intervention outcomes. Results suggest that only a very small percentage (6–12%) of studies used in previous meta-analytic studies were methodologically valid …

This study illuminates the experiences of K-12 educators as they strove to (re)build caring relationships with students during the COVID-19 pandemic. The study was conducted during a graduate course for experienced K-12 teachers in the spring of 2020 at a four-year comprehensive university in the United States. Data was collected from reflective learning journals and asynchronous peer discussions, which captured educators’ experiences as they transitioned to remote learning in real-time. Qualitative content analysis was used to identify pertinent themes. Findings suggest that remote learning revealed relationships in need of repair. Educators practiced authentic care and cultivated connectedness by (a) acting …

The Race To The Top To Reduce Prosecutorial Misconduct, Adam M. Gershowitz

Faculty Publications

This Essay offers an unconventional approach to deterring prosecutorial misconduct. Trial judges should use their inherent authority to forbid prosecutors from appearing and handling cases in their courtrooms until the prosecutors have completed training on Brady v. Maryland, Batson v. Kentucky, and other types of prosecutorial misconduct. If a single trial judge in a medium-sized or large jurisdiction imposes training prerequisites on prosecutors, it could set off a race to the top that encourages other judges to adopt similar (or perhaps even more rigorous) training requirements. A mandate that prosecutors receive ethics training before handling any cases is …

Spatial Mode Correction Of Single Photons Using Machine Learning, Narayan Bhusal, Sanjaya Lohani, Chenglong You, Mingyuan Hong, Joshua Fabre, Pengcheng Zhao, Erin M. Knutson, Ryan T. Glasser, Omar S. Magaña-Loaiza

Faculty Publications

Spatial modes of light constitute valuable resources for a variety of quantum technologies ranging from quantum communication and quantum imaging to remote sensing. Nevertheless, their vulnerabilities to phase distortions, induced by random media, impose significant limitations on the realistic implementation of numerous quantum-photonic technologies. Unfortunately, this problem is exacerbated at the single-photon level. Over the last two decades, this challenging problem has been tackled through conventional schemes that utilize optical nonlinearities, quantum correlations, and adaptive optics. In this article, the self-learning and self-evolving features of artificial neural networks are exploited to correct the complex spatial profile of distorted Laguerre–Gaussian modes …

Accelerated Controller Tuning For Wind Turbines Under Multiple Hazards, Aly Mousaad Aly, Milad Rezaee

Faculty Publications

During their lifecycle, wind turbines can be subjected to multiple hazard loads, such as high-intensity wind, earthquake, wave, and mechanical unbalance. Excessive vibrations, due to these loads, can have detrimental effects on energy production, structural lifecycle, and the initial cost of wind turbines. Vibration control by various means, such as passive, active, and semi-active control systems provide crucial solutions to these issues. We developed a novel control theory that enables semi-active controller tuning under the complex structural behavior and inherent system nonlinearity. The proposed theory enables the evaluation of semi-active controllers’ performance of multi-degrees-of-freedom systems, without the need for time-consuming …

We present modelling of the long-term optical light and radial velocity curves of the binary stellar system CXOGBS J175553.2-281633, first detected in X-rays in the Chandra Galactic Bulge Survey. We analysed 7 yr of optical I-band photometry from Optical Gravitational Lensing Experiment and found long-term variations from year to year. These long-term variations can most likely be explained with by either variations in the luminosity of the accretion disc or a spotted secondary star. The phased light curve has a sinusoidal shape, which we interpret as being due to ellipsoidal modulations. We improve the orbital period to be P = …

Second Languange Acquisition Of /S/ -Weakinging In A Study Abroad Context, Earl K. Brown, Alicia Harley, Bret Linford

Faculty Publications

This study examines the second language (L2) development of variable /s/-weakening in the spontaneous speech of L2 learners of Spanish who studied abroad in either Dominican Republic, where /s/-weakening is widespread, or central Spain, where /s/-weakening is much less common. Learners’ realizations of /s/ were coded impressionistically and acoustically by measuring voicing, center of gravity, and duration. The results show that regardless of the study abroad location, students did not change the amount of sibilance they produced over time. However, they became more nativelike with respect to /s/-voicing and duration. Additionally, whereas some linguistic factors were found to significantly constrain …

Juvenile Punishment, High School Graduation, And Adult Crime: Evidence From Idiosyncratic Judge Harshness, Ozkan Eren, Naci Mocan

Faculty Publications

This paper contributes to the debate on the impact of juvenile crime punishment on high school completion and adult recidivism using administrative data from a southern U.S. state. We exploit random assignment of cases to judges and use idiosyncratic judge stringency in imprisonment to estimate the causal effect of incarceration. We find that juvenile incarceration increases the propensity of being convicted for a drug offense in adulthood while it lowers the propensity to be convicted of a property crime. Juvenile incarceration has also a detrimental effect on high school completion for earlier cohorts, but it has no impact on later …

The Lost Promise Of Disability Rights, Claire Raj

Faculty Publications

Children with disabilities are among the most vulnerable students in public schools. They are the most likely to be bullied, harassed, restrained, or segregated. For these and other reasons, they also have the poorest academic outcomes. Overcoming these challenges requires full use of the laws enacted to protect these students’ affirmative right to equal access and an environment free from discrimination. Yet, courts routinely deny their access to two such laws—the Americans with Disabilities Act (ADA) and section 504 of the Rehabilitation Act of 1973 (section 504).

Courts too often overlook the affirmative obligations contained in these two disability rights …

A Corporate Law Rationale For Reparations, Susan S. Kuo, Benjamin Means

Faculty Publications

Should the United States pay reparations to African Americans? A majority of Americans object that they are not personally responsible for slavery or Jim Crow. The objection is rooted in the principle of ethical individualism, which holds that people can be blamed only for their own actions.

This Article contends that the ethical individualism objection to reparations is misplaced because it assumes that what matters is the culpability of each citizen. We argue that, like a corporation, the United States is a legal person. Consequently, seeking reparations from the United States does not turn on the guilt of its citizens …
