Identification Of Delamination Defects In Cfrp Materials Through Lamb Wave Responses, Taylor John Bruhschwein

Civil and Environmental Engineering

Delamination is currently a largely undetectable form of damage in composite laminate materials. This thesis will develop a method to more easily detect delamination damage within composite materials. Using finite element analysis modeling and lab testing, a new method from interpreting the results obtained from existing structural health monitoring techniques is developed. Lamb waves were introduced and recorded through an actuator and sensors made of piezoelectric material. The data was then analyzed through a novel data reduction method using the Fast Fourier Transform (FFT). Using the data from FFT, the idea of covariance of energy change was developed. By comparing …

Modeling Of Temperature Impacts On Fixed Film Microbial Growth And Nitrification Kinetics, Jacob Strombeck

Civil and Environmental Engineering

Monod-type kinetic models, used in simulating microbial growth in biological treatment systems, suggest significant decreases of substrate utilization at lower temperatures. However, it is documented that performance of fixed film treatment systems are not hindered with declining temperatures. Previous studies at the Moorhead, MN, Wastewater Treatment Facility (WWTF) showed significant impacts of temperature on biofilm growth in its moving bed biofilm reactor (MBBR), and studies noted that at low temperatures more biomass was present. Previously, a series of kinetic bench-scale batch tests was performed to measure ammonium removal in the full-scale system. As part of this research, a diffusion based …

Microtopography-Dominated Discontinuous Overland Flow Modeling And Hydrologic Connectivity Analysis, Jun Yang

Civil and Environmental Engineering

Surface microtopography affects a series of complex and dynamic hydrologic and environmental processes that are associated with both surface and subsurface systems, such as overland flow generation, infiltration, soil erosion, and sediment transport. Due to the influence of surface depressions, overland flow essentially features a series of progressive puddle-to-puddle (P2P) filling, spilling, merging, and splitting processes; and hydrologic systems often exhibit threshold behaviors in hydrologic connectivity and the associated overland flow generation process. It is inherently difficult to realistically simulate the discontinuous overland flow on irregular topographic surfaces and quantify the spatio-temporal variations in dynamic behaviors of topography-dominated hydrologic systems. …

Faculty Scholarship

This is the conclusion for an edited volume on legislative usage of foreign and international law, N. Lupo & L. Scaffardi, Legal Transplants and Parliaments: A Possible Dialogue Amongst Legislators? (2014). I assess the general turn in comparative law studies towards the behavior of elected officials, as well as the preference for increased formality in the use of foreign law. The essays in this book analyze the legal experiences of Brazil, Namibia, Australia, South Africa, Spain, the European Union, China, Canada, Portugal, the United Kingdom, the United States, and Italy. Many of these countries (but not all, especially the U.S.) …

The Market In Unmatured Tort Claims: Twenty-Five Years Later, Stephen G. Marks

Faculty Scholarship

In an article in 1989 in the Virginia Law Review, Professor Robert Cooter argued for changes in the law that would facilitate the development of a market in unmatured tort claims. An unmatured tort claim is a potential claim that a potential victim has before any injury has occurred. Cooter proposed that potential victims have the right to sell their unmatured tort claims. That is, Cooter proposed that potential victims be allowed to sell their right to sue even before an accident or injury ever occurs. Even twenty-five years later, the proposal remains both bold and imaginative, and yet it …

A Hermeneutic Exploration Of And Proposed Solution To The Schism Between Researchers And Clinicians Inpsychology, Mark S. Green

All-Inclusive List of Electronic Theses and Dissertations

Fragmentation in the field ofPsychology has persisted throughout its history (Slife, 2000). One example of this fragmentation is the gap between researchers and clinicians (Teachman, Drabick, Hershenberg, Vivian, & Wolfe 2012). Although many attempts have been made to bridge this gap, there is still no consensus regarding its resolution. ThisDissertation provides an explanation for the gap at the philosophical level and provides a method for communicating across potentially incommensurable philosophies, based on Gadamer's (1960/1989) hermeneutic opus: Truth and Method.

Moderating Effects Of Religious Orientation On The Relationship Between Sexual Self-Discrepancies And Guilt And Anxiety, Ann E. Jones

All-Inclusive List of Electronic Theses and Dissertations

The current study examined the moderating effect of religious orientation on the relationship between sexual self-discrepancies and guilt. There is some evidence of a positive correlation between sex-guilt and higher levels of religiosity. In this study it was proposed that sex-guilt in religious individuals is partially driven by discrepancies between actual sexual behaviors and how the individual thinks that they ought or ideally should behave. In order to test this idea a survey was administered to 151 undergraduate students to assess religious orientation, actual, ought, and ideal sexual behaviors, and sex guilt. Gender differences were found in reporting intrinsic religiosity, …

The Effects Of Reflective Prompts On Attention In Restorative And Non-Restorative Environments, Ryan Dumke

All-Inclusive List of Electronic Theses and Dissertations

Attention Restoration Theory (Kaplan, 1995) posits that the prolonged use of directed attention results in directed attention fatigue and that exposure to environments with restorative properties leads to increased attentional capacities. Despite a great deal of evidence illustrating this effect, there has been little research into the specific mechanisms accounting for this effect, and no research examining what is occurring in the mind during the restorative process. Most researchers have operated on the assumption that the relaxation of directed attention faculties accounts for the effect of attention restoration, with little evidence to completely support this assumption. However, conflicting evidence suggests …

In Territorio Veritas? Bringing Geographical Coherence Into The Ambiguous Definition Of Geographical Indications Of Origin, Irene Calboli

Research Collection Yong Pung How School Of Law

In this article, I criticize what I call “ambiguous geographical origin” in the concept of geographical indications of origin (GIs) and note that the current definition of GIs in Art. 22(1) of TRIPS essentially misuses, or at least misinterprets, of the terms “geographical origin.” More specifically, I expose the partial inconsistency between the legal definition under TRIPs and the dictionary definition of the terms “geographical” and “origin”. In this respect, I point out that, from a strictly linguistic standpoint, the term “geographical”, in its variation as “geographic”, is defined as “of or relating to geography” and as “belonging to or …

“Where Does A Wise Man Hide A Leaf?” : Modernising The Laws Of Disclosure In The Information Age, Denise Huiwen Wong

Research Collection Yong Pung How School Of Law

Litigation practice has been significantly altered by the advent of electronically stored information in daily corporate life. It is argued that the laws of disclosure should be updated to recognise that technology-assisted document review via keyword searching is crucial in ensuring that the costs of litigation are well managed. In order to facilitate keyword searching, a new legal concept of accuracy in the selection of keywords should be introduced into the laws of disclosure. At the same time, despite the adversarial nature of litigation, it is imperative that parties approach electronic disclosure with a spirit of collaboration in order to …

Teachers' Experiences With Disengagement In Physical Education Classes At Secondary School Level In The Perth Metropolitan Area, Nuno Matos Oliveira

Theses: Doctorates and Masters

Students’ disengagement from school has been one of the major concerns in educational research (Fredricks, Blumenfeld, & Paris, 2004). According to researchers (Alexander et al., 1997; Finn & National Center for Education Statistics, 1993; Finn & Rock, 1997; Finn & Voelkl, 1993; Fredricks & Blumenfeld et al., 2004) the more disengaged the students are, the more likely they will be to fail academically and ultimately drop out. Although researchers have already identified several risk factors that can influence students’ engagement (Fulton, 2007; Lee & Burkam, 2003; Newmann, 1992), very few studies have explored teachers’ views of this educational issue. The …

The Perceived Personal Characteristics Of Entrepreneurial Leaders, Ling He

Theses: Doctorates and Masters

The concept of entrepreneurial leadership has attracted growing interest from leadership scholars but research is still in an early stage and empirical studies are rare. This thesis explores this new concept in an empirical study of the personal characteristics of entrepreneurial leaders (ELs). The study is underpinned by the “common characteristics” model in which ELs have characteristics of both entrepreneurs and leaders. Semi-structured interviews and a short questionnaire were used to explore business owners’ and corporate managers’ perceptions of the personal characteristics of ELs. Responses were summarised with thematic analysis and descriptive statistics.

The findings show participants perceived EL as …
