Dredging For Environmental Benefit: Models Of Circulation And Flushing Dynamics In The Providence River Estuary, Grace Elizabeth Medley

Open Access Master's Theses

In estuarine dynamics, circulation in the form of mixing and exchange have a direct link to the water quality. Edgewood Shoals is a highly anthropogenically impacted region of the Providence River bordered by three cities, and receives the outfall from six wastewater treatment facilities. Edgewood Shoals also has low dissolved oxygen levels during the summer months. The Shoal is classified as a circulation-restricted zone, where hydrodynamic exchange is limited due to the steep bathymetric gradient created by an adjacent federal shipping channel. The US Army Corps of Engineers (USACE) is in the process of determining if there are options for …

Localization Of A Drifting Underwater Vehicle Using A Terrain-Based Particle Filter, Emanuele Raggi

Open Access Master's Theses

In this paper we present a terrain-aided particle filter to localize a freely drifting underwater vehicle. The vehicle is a bottom imaging Lagrangian float used for habitat classification, monitoring and fish abundance. During operation the vehicle captures down looking images at a controlled altitude above the bottom. Direct navigation information is often, but not always, recorded with a ultra short baseline (USBL) acoustic system. The presented methodology provides an alternate method for georeferencing when USBL is unavailable. The implemented particle filter utilizes a background bathymetry map and visual odometry as a motion mode. The particle filter is implemented using the …

Exploring Typology Categorizations Of Male Perpetrators: A Methodology Study, Emilyl N. Weber, Ashely R. Taylor, Arturo L. Cantos, Barbara G. Amado, K. Daniel O'Leary

Psychological Science Faculty Publications

Intimate partner violence (IPV) perpetrators were categorized based on whether they were generally violent (GV) or family only violent (FO) using self-report or arrest records. Classification criteria to assess recidivism in perpetrators of IPV were evaluated herein to determine the incremental validity of using a perpetrator’s criminal history in addition to their self-report information for categorization purposes. The concordance rates for categorizing subtypes of male perpetrators were compared for two methods, namely, self-report versus criminal history data. Categorizations were made based on self-reported history of violence and federal criminal records separately. Between measures consistency was defined as whether or not …

Side-To-Side Comparison Of Total Shoulder Arthroplasty And Intact Function In Individuals, Sarah Rose Walden

Electronic Theses and Dissertations

Total Shoulder Arthroplasty (TSA) is a surgery which replaces the shoulder joint, or the interface between the humerus and the scapula glenoid. To test TSA success, most prior research compares patients with TSA to healthy controls. However, the shoulder anthropometry, motion, and musculature of individuals varies widely across the population making it important to assess TSA performance in individuals. The overall goal of this study is to determine if patients with one of two TSA implant designs on one side achieve the same range of motion as their intact side, and if so to find if they compensate using increased …

Academic Experiences In Policy Development: A Grounded Theory Study Across Three Higher Education Institutions, Marie Brennan

Irish Journal of Academic Practice

The National Strategy for Higher Education to 2030 (Hunt Report, 2011) suggested that a framework should be put in place to facilitate institutional mergers. Subsequently, three institutes of technology in Dublin signed a memorandum of understanding establishing the Technological University for Dublin Alliance (Dublin Institute of Technology, the Institute of Technology Tallaght and the Institute of Technology Blanchardstown.) The presidents from each institute formed a steering group that consisted of a team of staff from across the three campuses. The role of this team was to launch the foundation themes that were necessary for designation. One of these themes was …

Place Recognition In Challenging Conditions, Saravanabalagi Ramachandran, John Mcdonald

Session 2: Deep Learning for Computer Vision

Place recognition in a visual SLAM system helps build and maintain a map from multiple traversals of the same environment while closing loops to correct drift accumulated over time. Despite the marked success in visual place recognition research over the past decade, it remains a challenging problem in the context of variations caused due to different times of the day, weather, lighting and seasons. In this paper, we address this problem by progressively training convolutional neural networks in a siamese fashion to generate embeddings that encode semantic and visual features for sequence-aligned image pairs taken at different timescales and viewpoints. …

Deep Convolutional Neural Networks For Estimating Lens Distortion Parameters, Sebastian Lutz, Mark Davey, Aljosa Smolic

Session 2: Deep Learning for Computer Vision

In this paper we present a convolutional neural network (CNN) to predict multiple lens distortion parameters from a single input image. Unlike other methods, our network is suitable to create high resolution output as it directly estimates the parameters from the image which then can be used to rectify even very high resolution input images. As our method it is fully automatic, it is suitable for both casual creatives and professional artists. Our results show that our network accurately predicts the lens distortion parameters of high resolution images and corrects the distortions satisfactory.

Principles Or Templates? The Antecedents And Performance Effects Of Cross-Border Knowledge, James B. Oldroyd, Shad Morris, Jeff P. Dotson

Faculty Publications

Managers understand the importance of knowledge management systems for project-based work. Efforts are often made to ensure knowledge is codified and disseminated throughout the firm so employees can draw upon them to complete their projects. Unfortunately, however, such efforts often lead to stockpiles of information that remain untapped and underutilized. This study seeks to answer two questions. First, how can managers influence workers to utilize different types of codified knowledge in the first place? Second, do different types of codified knowledge have differential effects on performance? We find that increased individual experience drives the use of knowledge principles while workers …

Research outputs 2014 to 2021

Background: A significant number of melanoma patients experience recurrence to distant sites, despite having had surgical treatment of the primary lesion, with curative intent. Monitoring of patients for early evidence of disease recurrence would significantly improve management of the disease, allowing timely therapeutic intervention. Circulating tumor DNA (ctDNA) is becoming a well-recognized biomarker for monitoring malignancies and has, in a few studies, been shown to signify disease recurrence earlier than conventional methods.

Methods: We performed a retrospective analysis of plasma ctDNA using droplet digital PCR (ddPCR) in 30 primary melanoma patients with tumors harboring BRAF, NRAS or TERT promoter mutations. …

Climate Change From A Distance: An Analysis Of Construal Level And Psychological Distance From Climate Change, Susie Wang, Mark J. Hurlstone, Zoe Leviston, Iain Walker, Carmen Lawrence

Research outputs 2014 to 2021

The public perception of climate change as abstract and distant may undermine climate action. According to construal level theory, whether a phenomenon is perceived as psychologically distant or close is associated with whether it is construed as abstract or concrete, respectively. Previous work has established a link between psychological distance and climate action, but the associated role of construal level has yet to be explored in depth. In two representative surveys of Australians (N = 217 and N = 216), and one experiment (N = 319), we tested whether construal level and psychological distance from climate change predicted …

Nitric oxide (NO) facilitates anti-atherosclerotic effects. Vegetables are a major source of dietary nitrate. Experimental data indicates that dietary nitrate can significantly reduce major risk factors for atherosclerosis and subsequent cardiovascular disease (CVD), as nitrate can be metabolized to produce NO via the nitrate-nitrite-NO pathway. The purpose of this study was to prospectively investigate the association between habitual dietary nitrate intakes and the incidence of self-reported CVD-related complications within a representative sample of middle-aged Australian women (1946–1951 cohort of the Australian Longitudinal Study on Women’s Health). Women free from disease at baseline who had completed the food frequency questionnaire data …

Research outputs 2014 to 2021

A foundation of medical research is time series analysis—the behavior of variables of interest with respect to time. Time series data are often analyzed using the mean, with statistical tests applied to mean differences, and has the assumption that data are stationary. Although widely practiced, this method has limitations. Here we present an alternative statistical approach with sample analysis that provides a summary statistic accounting for the non-stationary nature of time series data. This work discusses the use of entropy as a measurement of the complexity of time series, in the context of Neuroscience, due to the non-stationary characteristic of …

Cannabis Consumption Patterns Explain The East-West Gradient In Canadian Neural Tube Defect Incidence: An Ecological Study, Albert Stuart Reece, Gary Kenneth Hulse

Research outputs 2014 to 2021

While a known link between prenatal cannabis exposure and anencephaly exists, the relationship of prenatal cannabis exposure with neural tube defects (NTDs) generally has not been defined. Published data from Canada Health and Statistics Canada were used to assess this relationship. Both cannabis use and NTDs were shown to follow an east-west and north-south gradient. Last year cannabis consumption was significantly associated (P < .0001; cannabis use–time interaction P < .0001). These results were confirmed when estimates of termination for anomaly were used. Canada Health population data allowed the calculation of an NTD odds ratio) of 1.27 (95% confidence interval = 1.19-1.37; P < 10⁻¹¹) for high-risk provinces versus the remainder with an attributable fraction in exposed populations of 16.52% (95% confidence interval = 12.22-20.62). Data show a robust positive statistical association between cannabis consumption as both …

Hordein Accumulation In Developing Barley Grains, Gregory J. Tanner, Michelle L. Colgrave, Malcolm J. Blundell, Crispin A. Howitt, Antony Bacic

Research outputs 2014 to 2021

The temporal pattern of accumulation of hordein storage proteins in developing barley grains was studied by enzyme-linked immunosorbent assay (ELISA), western blot and liquid chromatography tandem mass spectrometry (LC-MS/MS). Hordein accumulation was compared to the pattern seen for two abundant control proteins, serpin Z4 (an early accumulator) and lipid transferase protein (LTP1, a late accumulator). Hordeins were detected from 6 days post-anthesis (DPA) and peaked at 30 DPA. Changes in fresh weight indicate that desiccation begins at 20 DPA and by 37 DPA fresh weight had decreased by 35%. ELISA analysis of hordein content, expressed on a protein basis, increased …

A Corrective Justice Justification For Considering The Response Of The Hypothetical Person Of An “Ordinary Level Of Susceptibility” When Assessing Reasonable Foreseeability In Cases Involving Negligently Inflicted Psychiatric Injury, Martin Allcock

Research outputs 2014 to 2021

The law has long been concerned with limiting recovery for pure psychiatric injury in negligence in order to prevent liability to plaintiffs who are unusually susceptible to this type of injury. The justifications provided by courts for this concern have often centred on the idea that holding a defendant liable to such a plaintiff will be unreasonable. However, there is a gap in the reasoning of the courts and in the scholarly literature as to the potential theoretical justifications for measuring the reasonableness of the defendant’s conduct against the effect of that conduct on the hypothetical person of an “ordinary …

Essays: Color-Blind Or Race-Conscious Policies, Gus Castro, Hannah Lyons, Anna Eager, Jonathan Panton

Res Publica - Journal of Undergraduate Research

The debate between advocates color blind and race conscious policies has been perennial in the United States since Reconstruction and has recently been resuscitated in the popular press with the publication of Michelle Alexander’s The New Jim Crow: Mass Incarceration in the Age of Color Blindness (2010). Alexander’s book provided support for the race conscious side and students read Nathan Glazer’s Affirmative Discrimination: Ethnic Inequality and Public Policy (1975) for a defense of the color blind side. The debate was framed in an even-handed manner by a selection from Desmond King and Rogers M. Smith’s Still a House Divided: Race …

Facial Identification For Digital Forensic, Hiba Al-Kawaz

School of Engineering, Computing and Mathematics Theses

Forensic facial recognition has become an essential requirement in criminal investigations as a result of the emergence of electronic devices, such as mobile phones and computers, and the huge volume of existing content. Forensic facial recognition goes beyond facial recognition in that it deals with facial images under unconstrained and non-ideal conditions, such as low image resolution, varying facial orientation, poor illumination, a wide range of facial expressions, and the presence of accessories. In addition, digital forensic challenges do not only concern identifying an individual but also include understanding the context, acknowledging the relationships between individuals, tracking, and numbers of …

Computational Study Of Neuronal Oscillations In Motor Control Circuits, Andrea Ferrario

School of Engineering, Computing and Mathematics Theses

In this thesis we used mathematical and computational models to study neuronal net- works that control motor behaviours. Specifically, we modelled two neuronal circuits from two opposite ends of the brain complexity spectrum: the swimming circuit of the hatchling Xenopus tadpole and the human basal ganglia. Due to its relative simplicity, tadpole is a unique animal for studying locomotion us- ing both experiments and models. This allowed us to define three biologically-realistic spiking models to clarify the interplay between the architecture of synaptic connections (structure) and the network’s ability to generate activities that correspond to its swim- ming behaviour (function). …

Does Audit Committee Accounting Expertise Help To Promote Audit Quality? Evidence From Auditor Reporting Of Internal Control Weaknesses*, Ling Lei Lisic, Linda A. Myers, Timothy Seidel, Jian Zhou

Faculty Publications

In this study, we examine whether audit committee accounting expertise helps to promote audit quality by motivating auditors to conduct diligent internal control audits and make appropriate internal control assessments because audit committee accounting expertise safeguards auditors from dismissal following adverse internal control opinions. Among clients with existing and likely internal control material weaknesses (as proxied by future restatements of audited financial statements), we find a greater likelihood of adverse internal control audit opinions when the audit committee has greater accounting expertise (measured by the proportion of accounting experts on the audit committee). Among all clients, we find a lower …
