Mobile Ka-Band Polarimetric Doppler Radar Observations Of Wildfire Smoke Plumes, Taylor Brianna Aydell

Master's Theses

Remote sensing techniques have been more recently used to study and track wildfire smoke plume structure and evolution; however, knowledge gaps remain due to the limited availability of observational datasets aimed at understanding the fine-scale fire-atmosphere interactions and plume microphysics. In this study, we present a new mobile millimeter-wave (Ka-band) Doppler radar system acquired to sample the fine-scale kinematics and microphysical properties of active wildfire smoke plumes from both wildfires and large prescribed fires. Four field deployments were conducted in the fall of 2019 during two wildfires in California and one prescribed burn in Utah. An additional dataset of precipitation …

Faculty Research, Scholarly, and Creative Activity

With the advancement of wireless access networks and mmWave New Radio (NR), new applications emerged, which requires a high data rate. The random packet loss due to mobility and channel conditions in a wireless network is not negligible, which degrades the significant performance of the Transmission Control Protocol (TCP). The TCP has been extensively deployed for congestion control in the communication network during the last two decades. Different variants are proposed to improve the performance of TCP in various scenarios, specifically in lossy and high bandwidth-delay product (high- BDP) networks. Implementing a new TCP congestion control algorithm whose performance is …

Improvement Of Tcad Augmented Machine Learning Using Autoencoder For Semiconductor Variation Identification And Inverse Design, Kashyap Mehta, Sophia Susan Raju, Ming Xiao, Boyan Wang, Yuhao Zhang, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

A machine learning (ML) model by combing two autoencoders and one linear regression model is proposed to avoid overfitting and to improve the accuracy of Technology Computer-Aided Design (TCAD)-augmented ML for semiconductor structural variation identification and inverse design, without using domain expertise. TCAD-augmented ML utilizes TCAD simulations to generate sufficient data for ML model development when experimental data are inadequate. The ML model can then be used to identify semiconductor structural variation for given experimental electrical measurements. In this study, the variation of layer thicknesses in the p-i-n diode is used as a demonstration. An ML model is developed to …

Countering Deficit Thinking About Neurodiversity Among General Education Teacher Candidates: A Case Discussion Approach, Grinell Smith, Colette Rabin

Faculty Research, Scholarly, and Creative Activity

We have observed that many of the multiple-subjects teacher credential candidates in our program often reveal deficit views of autistic children. This report provides an example of how we help credential candidates learn to reframe deficit thinking about neurodiversity via the examination, discussion, and dramatization of a collection of dilemma-based case stories designed to help our students unearth preconceptions and engage in shared inquiry. One strength of this approach is that it asks candidates to develop specific and realistic plans of action, to adopt a care ethic requiring them to think and act from the perspective of the child, to …

Racial Purges, Robert L. Tsai

Faculty Scholarship

In a two-year period, 1885-86, over 168 communities in America forcibly expelled Chinese residents from their midst. This essay, inspired by historian Beth Lew-Williams's book, THE CHINESE MUST GO, investigates the nineteenth-century purges of Chinese residents that occurred throughout the American west. I make three arguments. First, these acts of racial and political terror complicate our understanding of racial violence in America. Many of the actions were denounced, but they were also surprisingly effective in forcing business and political leaders to support the indefinite suspension of Chinese migration. Perpetrators faced almost no legal repercussions, and unlike for freed persons, racial …

OHSU-PSU School of Public Health Faculty Publications and Presentations

We previously discovered microRNAs (miRNAs) in cerebrospinal fluid (CSF) that differentiate Alzheimer’s disease (AD) patients from Controls. Here we examined the performance of 37 candidate AD miRNA biomarkers in a new and independent cohort of CSF from 47 AD patients and 71 Controls on custom TaqMan arrays. We employed a consensus ranking approach to provide an overall priority score for each miRNA, then used multimarker models to assess the relative contributions of the top-ranking miRNAs to differentiate AD from Controls. We assessed classification performance of the top-ranking miRNAs when combined with apolipoprotein E4 (APOE4) genotype status or CSF amyloid-β42 (Aβ42):total …

Narrative Therapy To Reduce Self-Stigma: Empowering Children, Adolescents, And Their Families, Jillian Baldwin

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

The effects of self-stigma on children and adolescents with mental health diagnoses is a documented psychological issue in academic literature; however, no studies or articles to date present strategies for reducing its negative effects. Additionally, very few studies have connected the experience of parental stigma, or courtesy/affiliate stigma, and its effects on child and family well-being. Self-stigma has been conceptualized as existing on the opposite end of the spectrum from empowerment, suggesting that empowerment may serve as a promising approach to tackling self-stigmatization. This paper presents a novel therapeutic intervention for reducing self-stigma in children, adolescents, and their families through …

The Role Of Awareness In Traumatic Brain Injuries: Interviews With Experts, Dominique Chao

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Approximately 2.8 million US citizens sustain a traumatic brain injury (TBI) annually, with more than 275,000 requiring inpatient rehabilitation (Taylor, Bell & Breiding, 2013). As rehabilitation techniques are refined and adapted to increase the speed of recovery and functional independence following TBIs, there is an ongoing need for better prognostic assessment tools. Research has shown that a lack of self-awareness following TBI is associated with poorer outcomes (e.g. employability, community reintegration) following discharge from inpatient hospitalizations (Cheng & Man, 2006; Robertson & Schmitter, 2016) and can result in decreased motivation (Simmonds & Fleming, 2003), compromised safety, poor community re-integration, and …

Covid-19 And Individuals With Developmental Disabilities: Tragic Realities And Cautious Hope, Samuel J. Levine

Scholarly Works

The COVID-19 pandemic has cast the United States, along with the rest of the world, into a time of crisis and uncertainty unlike any other in recent memory. Months into the pandemic, there is scant agreement among scientists, government officials, and large segments of the public, both domestic and abroad, as to determining the causes and workings of the virus, designing appropriate and effective responses to the outbreak, and constructing accurate assessments of the future—or even of the present. Indeed, the availability of concrete information about the virus and its effects is grossly inadequate and often replaced by anecdotal or …

Access Law Schools & Diversifying The Profession, Deseriee A. Kennedy

Scholarly Works

Lawyers do not reflect the racial diversity in the United States. The legal profession continues to struggle with ways to achieve and maintain racial diversity. Law schools play a critical role in the path to practice, and therefore an examination of the barriers to the profession they created is warranted. This essay critiques the over-reliance on standardized testing in law school admissions and advocates for an open admissions process that prioritizes racial and academic diversity. It suggests that the benefits of minimizing the role of standardized tests far outweigh any perceived costs in legal education. This essay concludes that the …

A New Flexible Bathtub-Shaped Modification Of The Weibull Model: Properties And Applications, Qinghu Liao, Zubair Ahmad, Eisa Mahmoudi, Gholamhossein Hamedani

Mathematical and Statistical Science Faculty Research and Publications

Many studies have suggested the modifications and generalizations of the Weibull distribution to model the nonmonotone hazards. In this paper, we combine the logarithms of two cumulative hazard rate functions and propose a new modified form of the Weibull distribution. The newly proposed distribution may be called a new flexible extended Weibull distribution. Corresponding hazard rate function of the proposed distribution shows flexible (monotone and nonmonotone) shapes. Three different characterizations along with some mathematical properties are provided. We also consider the maximum likelihood estimation procedure to estimate the model parameters. For the illustrative purposes, two real applications from reliability engineering …

Marshall-Olkin Power Lomax Distribution: Properties And Estimation Based On Complete And Censored Samples, Muhammad Ahsan Ul Haq, Gholamhossein Hamedani, M. Elgarhy, Pedro Luiz Ramos

Mathematical and Statistical Science Faculty Research and Publications

We study a new distribution called the Marshall-Olkin Power Lomax distribution. A comprehensive account of its mathematical properties including explicit expressions for the ordinary moments, moment generating function, order statistics, Renyi entropy, and probability weighted moments are derived. The model parameters are estimated by the method of maximum likelihood. Monte Carlo simulation study is carried out to estimate the parameters and the performance of the estimates is judged via the average biases and mean squared error values. The usefulness of the proposed model is illustrated via real-life data set.

Examining The Complex Relationship Between Innovation And Regulation Through A Survey Of Wastewater Utility Managers, Luke Sherman, Alida Cantor, Anita Milman, Michael Kiparsky

Geography Faculty Publications and Presentations

Despite pressures to increase performance and decrease costs, innovation has been slow to emerge in the municipal wastewater sector. The relationship between regulation and innovation in this sector is a particularly interesting aspect of this conundrum, given the degree to which public utility decision-making is influenced by regulation. Using a national survey, this paper examines US wastewater utility managers’ perceptions of how regulation influences the adoption of new technologies. Recognizing that the relationship between innovation and regulation is complex, we develop the concept of regulation as multifaceted and examine three interrelated aspects of regulation: (1) regulatory requirements, (2) regulators and …

Globular Clusters In Coma Cluster Ultra-Diffuse Galaxies (Udgs): Evidence For Two Types Of Udg?, Duncan A. Forbes, Adebusola Alabi, Aaron J. Romanowsky, Jean P. Brodie, Nobuo Arimoto

Faculty Research, Scholarly, and Creative Activity

Ultra-diffuse galaxies (UDGs) reveal extreme properties. Here, we compile the largest study to date of 85 globular cluster (GC) systems around UDGs in the Coma cluster, using new deep ground-based imaging of the known UDGs and existing imaging from the Hubble Space Telescope of their GC systems. We find that the richness of GC systems in UDGs generally exceeds that found in normal dwarf galaxies of the same stellar mass. These GC-rich UDGs imply haloes more massive than expected from the standard stellar mass–halo mass relation. The presence of such overly massive haloes presents a significant challenge to the latest …

Unstructured Data For Cybersecurity And Internal Control, Jesus Canelón, Esperanza Huerta, Normal Leal, Terry Ryan

Faculty Research, Scholarly, and Creative Activity

This paper proposes a research framework for studying the connections-realized and potential-between unstructured data (UD) and cybersecurity and internal controls. In the framework, cybersecurity and internal control goals determine the tasks to be conducted. The task influences the types of UD to be accessed and the types of analysis to be done, which in turn influences the outcomes that can be achieved. Patterns in UD are relevant for cybersecurity and internal control, but UD poses unique challenges for its analysis and management. This paper discusses some of these challenges including veracity, structuralizing, bias, and explainability.
