Using Tensor Factorisation Models To Separate Drums From Polyphonic Music, Derry Fitzgerald, Matt Cranitch, Eugene Coyle

Conference papers

This paper describes the use of Non-negative Tensor Factorisation models for the separation of drums from polyphonic audio. Improved separation of the drums is achieved through the incorporation of Gamma Chain priors into the Non-negative Tensor Factorisation framework. In contrast to many previous approaches, the method used in this paper requires little or no pre-training or use of drum templates. The utility of the technique is shown on real-world audio examples.

Time Reversal Of Continuous-Wave, Steady-State Signals In Elastic Media, Brian E. Anderson, Robert A. Guyer, Paul A. Johnson, Timothy J. Ulrich

Faculty Publications

Experimental observations of spatial focusing of continuous-wave, steady-state elastic waves in a reverberant elastic cavity using time reversal are reported here. Spatially localized focusing is achieved when multiple channels are employed, while a single channel does not yield such focusing. The amplitude of the energy at the focal location increases as the square of the number of channels used, while the amplitude elsewhere in the medium increases proportionally with the number of channels used. The observation is important in the context of imaging in solid laboratory samples as well as problems involving continuous-wave signals in Earth.

Focusing On Process And History: Path Dependence, Paul Donnelly

Articles

In recognition of the calls for more processual and historically informed organizational theorizing, this chapter considers the notion of path dependency, an approach which holds that a historical path of choices has the character of a branching process with a self-reinforcing dynamic such that preceding steps in a particular direction induce further movement in the same direction, thereby making the possibility of switching to some other previously credible alternative more difficult. Path dependence seeks to assess how process, sequence and temporality can be best incorporated into explanation, the focus of the researcher being on particular outcomes, temporal sequencing and the …

The Design By Molecular Dynamics Modeling And Simulations Of Porous Polymer Adsorbent Media Immobilized On The Throughpore Surfaces Of Polymeric Monoliths, E. Riccardi, J. C. Wang, A. I. Liapis

Chemical and Biochemical Engineering Faculty Research & Creative Works

Ion-exchange porous adsorbent media having intermediate and low surface densities of dextran polymer grafted on the surface of the through pores of polymeric monoliths are constructed and characterized by a molecular dynamic modeling and simulation approach that has also been shown to be effective in the construction and characterization of porous ion-exchange adsorbent media whose number of immobilized dextran polymer chains per unit surface area is high. the activation step that prepares the surface of the pores of the dextran polymer layer for the immobilization of the charged ligands insignificantly affected the pore structure of the dextran polymer layer, while …

Preliminary Investigation Of Novel Bone Graft Substitutes Based On Strontium-Calcium-Zinc-Silicate Glasses, D. Boyd, G. Carroll, Mark R. Towler, C. Freeman, P. Farthing, I. M. Brook

Chemical and Biochemical Engineering Faculty Research & Creative Works

Bone graft procedures typically require surgeons to harvest bone from a second site on a given patient (Autograft) before repairing a bone defect. However, this results in increased surgical time, excessive blood loss and a significant increase in pain. In this context a synthetic bone graft with excellent histocompatibility, built in antibacterial efficacy and the ability to regenerate healthy tissue in place of diseased tissue would be a significant step forward relative to current state of the art philosophies. We developed a range of calcium-strontium-zinc-silicate glass-based bone grafts and characterized their structure and physical properties, then evaluated their in vitro …

A Test Of Tmt: Mortality Salience And Avoidance Of Worldview Threats, Taylor Wayne Wadian

Dissertations and Theses @ UNI

Imagine playing a game of catch with three people, and all the things that would influence to whom you throw. Were thoughts of death included as one of those factors? The hypothesis that mortality salience motivates avoidant behavior toward a worldviewthreatening target was empirically tested on a sample of 200 undergraduate Caucasian college students from a Midwestern university. I induced participants to write about either their own death or dental pain, and presented them with summer descriptions of three fictitious male African American targets that they believed they were going to interact with later in the study. Targets' descriptions were …

Spreadsheet Based Immediate Feedback Formative Assessments For Naïve Conception Recognition And Corrective Accommodation In The Physical Sciences, Jonnie R. Becker

Graduate Research Papers

Providing an education requires continuous assessment which is not feasible with traditional methodologies. This project involved the creation of a set of three formative assessment spreadsheet workbooks that provide instant feedback related to common naive conceptions of matter, change, and energy. Combining validity tested assessment items and constructivist learning theory as a base, multiple choice questions were placed into a series of Excel spreadsheet workbooks that are inter-referenced to instantly report student achievement and reasoning. These spreadsheets provide accurate, timely feedback to the students and the facilitator, as well as an opportunity for students to grow their understandings. This assessment …

Youth Volunteerism: By Looking At Who Volunteers And Why Organizations May Be Able To Recruit Youth To Become Long-Standing Volunteers, Kathryn M. Zimmerly

Graduate Research Papers

In 1835 Alexis de Tocqueville suggested volunteerism could reduce antisocial or criminal behavior (Uggen and Janikula, 1999). When looking at volunteerism today researchers have concluded similar aspects; for example, Uggen and Janikula found in their 1999 research that volunteers had increased self -acceptance, instrumentality, and civic identity.

Research by the Independent Sector suggests that 70 percent of youth volunteers feel volunteering is important because it gives them a new perspective, allows them to participate for a good cause, and gives them a greater respect for the people they are helping. Youth volunteer levels have increased (to 70 percent from 59 …

Architects Of The Identity Of Dance: Gender Inequity In Achievement And Acknowledgment In Australian Contemporary Dance, Quindell Orton

Theses : Honours

Evidence suggests that males receive more opportunities, awards and dominate the dance scene in terms of artistic directorship of high visibility, large budget contemporary dance companies within Australia. This research investigates why and how males have come to be the architects of the identity of dance and the factors which may inhibit a counterpart female's likelihood of assuming the same role. Much of this paper deals with constructing hypotheses for how gender disparities in contemporary dance may have come about. In order to devise informed hypotheses, I have gathered data on government funding and national dance awards. In addition interviews …

The Communicating Dance, Alison Plevey

Theses : Honours

Does dance have the ability to communicate universally to all observers at some level of human engagement? This paper discusses theatre dance as a human communicative medium, the characteristics of how it communicates and to a certain degree why and what it communicates. In doing so the intentions of the communicating dancer and choreographer are considered alongside that of the receptive and responsive audience. The thesis compiles a survey of textual sources pin pointing the unique communicative abilities of dance, as an artistic, expressive and meaningful form of non-verbal communication establishing suggestions of the ways it may be universally communicable.

Financial Market Destabilization And The Role Of Credit Default Swaps: An International Perspective On The Sec's Role Going Forward, Janis P. Sarra

All Faculty Publications

International financial market participants and regulators are watching as the United States attempts to come to grips with the most serious consequences of the crisis in financial markets. Multiple strategies are being used, including bailouts, bank stimulus packages, recapitalization of financial institutions, insolvency restructurings, mortgage programs, guarantees for interbank lending, and direct asset purchases. The causes of the financial turmoil are numerous and complex, but one underlying cause was activities in the credit derivatives market. The fragmentation of regulation over the U.S. financial system, with at least five oversight bodies, has arguably resulted in significant gaps in regulatory oversight. The …

Accessing Insolvent Consumer Debtors, Challenges And Strategies For Empirical Research, Janis P. Sarra, Danielle Sarra

All Faculty Publications

Insolvency law policy is best informed by a comprehensive understanding of the policy objectives of particular measures and the practical outcomes of particular choices. Yet there continues to be a lack of empirical research in Canada in respect of consumer insolvency, its underlying causes and its outcomes. Debtors' or bankrupts' experience with the insolvency system is almost impossible to gauge with the data now collected. Research funding for legal, economic and sociological scholars in the insolvency area continues to be very limited. This paper examines current challenges and strategies for empirical research on consumer insolvency in Canada. It explores options …

Modeling Problems In Mucus Viscoelasticity And Mucociliary Clearance, Michael M. Norton

Theses

From the common cold and allergies to severe chronic and acute respiratory impairments, the function of the body's mucociliary clearance mechanism plays a primary defense role. Mucus demonstrates numerous non-Newtonian behaviors which set it apart from viscous fluids. Among them: Bingham plastic behavior, shear-thinning, and elasticity on short time scales due to relaxation time. Experimental evidence suggests that certain rheologies promote effective transport. In an effort to reveal the mechanisms controlling transport, models are developed. Firstly, a steady state model which idealizes the mucus as a rigid body is created in order to bring together disparate bodies of experimental work …
