Multi Pitch Estimation By Using Iir Comb Filters, Mikel Gainza, Robert Lawlor, Eugene Coyle

Conference papers

A technique for detecting the pitches of a polyphonic signal is presented. The system utilises modified IIR comb filters, which are generated to ensure that a null (stop band notches) exists at multiples of note frequencies and that a very flat pass band is present in the remain of the spectrum. Thus, the signal spectrum is not distorted after applying the filters to the audio signal, which is the case when using FIR comb filters. the presented approach improves upon an existing multi pitch detection model based on a FIR comb filter framework.

Field And Intensity Correlations In Amplifying Random Media, Alexey Yamilov, Shih-Hui Chang, Alexander Burin, Allen Taflove, Hui Cao

Physics Faculty Research & Creative Works

We study local and nonlocal correlations of light transmitted through active random media. The conventional approach results in divergence of ensemble-averaged correlation functions due to the existence of lasing realizations. We introduce a conditional average for correlation functions by omitting the divergent realizations. Our numerical simulation reveals that amplification does not affect local spatial correlation. The nonlocal intensity correlations are strongly magnified due to selective enhancement of the contributions from long propagation paths. We also show that by increasing gain, the average mode linewidth can be made comparable to the average mode spacing. This implies that light transport through a …

An Hmm-Based Framework For Video Semantic Analysis, Gu Xu, Yu-Fei Ma, Hong-Jiang Zhang, Shiqiang Yang

Chemistry Faculty Research & Creative Works

Video semantic analysis is essential in video indexing and structuring. However, due to the lack of robust and generic algorithms, most of the existing works on semantic analysis are limited to specific domains. In this paper, we present a novel hidden Markove model (HMM)-based framework as a general solution to video semantic analysis. In the proposed framework, semantics in different granularities are mapped to a hierarchical model space, which is composed of detectors and connectors. In this manner, our model decomposes a complex analysis problem into simpler subproblems during the training process and automatically integrates those subproblems for recognition. The …

Modulation Of Millimeter Waves By Acoustically Controlled Hexagonal Ferrite Resonator, Marina Koledintseva, Alexander A. Kitaytsev

Electrical and Computer Engineering Faculty Research & Creative Works

To develop millimeter-wave modulators, high-anisotropy uniaxial monocrystalline hexagonal ferrite resonators (HFRs) can be used. One of the ways to modulate the hexagonal ferrite resonator's resonance frequency is to periodically vary the angle between the equilibrium magnetic moment and the external magnetization field. This angular control can be exercised by the mechanical (acoustic) oscillations excited in a piezoelectric slab having a good acoustic contact with the HFR. We consider a quasi-static mathematical model of the uniaxial HFR with the angular control of its resonance frequency. We analyze the amplitudes of harmonics of the modulated millimeter-wave signal, and we derive the optimal …

The Chinese Approach To Electronic Transactions Legislation, Zhang Chu, Lingfei Lei

Computer Law Review and Technology Journal

Ecclesiastes reminds us that there is nothing new under the sun, and this may be equally true when it comes to electronic transactions. In the electronic world, agreements are still embodied in contracts, contracts are still entered into when two parties reach an enforceable agreement on terms, and objective evidence still determines whether an agreement has been reached. Fraud and piracy are no less illegal because they happen online. In other words, laws governing the physical world are also relevant in the virtual world. Nevertheless, despite all the similarities, there may still be some differences in form, and there are …

Spiritual Dimension In Educational Leadership, Rosalina Ruiz

Theses and Dissertations - UTB/UTPA

Spirit-filled experiences have been customarily silent in the discourse of education. This area has been misunderstood and solely left to the religious arena to discover its development creating compartmentalized concepts and depriving other organizational systems from implementing its rich resourcefulness. This study seeks to provide ontological and epistemological knowledge to uncover and understand the power of the spiritual dimension in the life of successful educational leaders. By conceptualizing spirituality in educational leadership, this qualitative study seeks to explore successful educational leaders' use of spirituality to strengthen their effectiveness as it relates to school and their performance. Based on the major …

Farming At Wylie : A Technical Biography 1933- 1963, Bruce Rhind

Theses : Honours

The genesis of this project was my father Graeme Rhind's collection of photographs of farming in Western Australia, dating back to 1929 when his parents first began farming in the wheatbelt near Wyalkatchem. I was interested in the way these photographs illustrated changing farming practices during the following three decades, and how they provided both documentary evidence and stimulated recall of memory. I was also concerned by the loss of knowledge of old photographic collections. The photographs are insufficient by themselves because each image requires specialised knowledge which the viewer may not possess, and that knowledge is lost with the …

Photocontrol Of Upper And Lower Rim Complexation Of Neutral And Cationic Species By P-Tert-Butylcalix[4]Arene Tetraethyl Ester, Mary Deasy, Bernadette Creaven, Brian A. Murray, Catherine Mckenna, Darren Tobin

Articles

A number of sodium salt complexes of p-tert-butylcalix[4]arene tetraethyl ester, 1, were isolated both with and without upper-rim encapsulated solvent. Selective decomplexation of lower rim bound sodium cations and upper rim encapsulated solvent molecules could be successfully achieved using low pressure light sources. Oxidation of the counter anion at the lower rim of p-tert-butylcalix[4]arene tetraethyl ester triggered both the upper and lower rim decomplexation process. The extent of decomplexation at both rims is controlled both by the nature of the counter-anionic species at the lower rim and by the fate of the photoproducts generated. The calixarene host …

Legislative Oversight Of Police: Lessons Learned From An Investigation Of Police Handling Of Demonstrations In Washington, D.C., Mary M. Cheh

GW Law Faculty Publications & Other Works

There are various ways to oversee police behavior including internal discipline, civilian review boards, civil law suits, and criminal prosecutions. These are important tools but an equally important but less examined mechanism is legislative oversight, and, in particular, the legislative investigation. A legislature may choose to review police policies concerning the use of surveillance, informants and undercover operatives, the implementation of community policing, the use of force, eradication of gang activity, and perhaps most prominently in the post 9/11 world, counter terrorism initiatives. All of these matters involve policy decisions at the departmental level and not actions taken at the …

The Labor Movement Needs A Twenty-First Century Committee For Industrial Organization, Charles B. Craver

GW Law Faculty Publications & Other Works

Following the enactment of the NLRA in 1935, American Federation of Labor craft unions had difficulty organizing persons employed in manufacturing industries since most failed to fit within the jurisdictions of particular unions. The AFL formed the Committee for Industrial Organization to determine how best to organize these workers, and this Committee ultimately withdrew from the AFL and formed the Congress of Industrial Organizations. The CIO unions quickly organized the industrial workers in the steel, automobile, electrical manufacturing, and rubber industries. By the late 1950s, 35 percent of private sector employees were union members. As the United States economy began …

Scholarly Profit Margins And The Legal Scholarship Network: Reflections On The Web, Lawrence A. Cunningham

GW Law Faculty Publications & Other Works

Controversy surrounding scholastic rankings arises, in part, because of complexities associated with measuring academic contributions. Legal researchers use various methodologies to assess scholarly production and impact but all suffer from inherent limitations and none provides data useful to scholarly self-reflection. The 10-year old Legal Scholarship Network (LSN) offers potential to improve considerably on both scores of public and personal assessment. This Essay critically evaluates approaches to conceptualizing scholarly profit margins, explores how LSN can enhance these conceptions, and opens new frontiers for this innovative Web-based repository of legal writing.

Then, the instruments,both active and passive, used for the measurement of radon concentration are discussed by taking into account their respective advantages and disadvantages for the use in the cave environment. Since in many countries radon is the object of regulations that were adopted for radiation protection purposes, this aspect is examined and the recommendations issued by international organisations and enforced in different countries are reported. Materials, methods and other remarks on the limits implementation are also listed with the …

Risky Business: Managing Interagency Acquisition, Steven L. Schooner

GW Law Faculty Publications & Other Works

This brief piece applauds the Government Accountability Office (GAO) for adding the management of interagency contracting to its High Risk List. It suggests that interagency acquisition, the poster child for the flexible, streamlined, businesslike approach of the 1990's acquisition reform movement, has become the federal procurement system's Achilles heel. It recommends that the government needs more qualified professionals to proactively craft results-oriented contracts and to manage effectively contractors' performance. Finally it suggests commencing a meaningful conversation about the appropriate role of businesslike models, generally, and fees, specifically, in governance.

An Investigation Of The Impact Of Visual Culture On Visual Arts Practice And Visual Arts Education, Robyn Roper

Theses: Doctorates and Masters

This research project is based on the premise that school students have a right to an education that assists them to "develop a sense of personal meaning and identity, and be encouraged to reflect critically on the ways in which that occurs." (Curriculum Frameworks, 1998, Values, Statement 2.2 Personal meaning: 325). Not only should education offer students a sense of well being, it should make a difference to their lives and foster an appetite for life long learning. A key ingredient that makes for a rich, fulfilling and rewarding life, is an understanding of visual culture, that according to Freedman …

Issues Of English Language Proficiency For International Students, Patricia Dooey

Theses: Doctorates and Masters

In the last 20 years or so, there has been a phenomenal increase in the number of international full-fee paying students applying to study in Australian universities, The revenue provided in this way has helped to address the problems faced by cash-starved universities facing recurring funding cuts over the same period. Furthermore, the presence of such students on any university campus provides immeasurable enrichment to the student body in terms of cultural diversity and research potential, and indeed it is very tempting in an ever,-increasing global market, to be as flexible as possible with prospective international students. However, the process …

Seven Decades Of Sports Writing At The West Australian (1901-1971), David R. Marsh

Theses: Doctorates and Masters

For a country whose identity is much bound up with sport, little research has been done so far into Sports journalism in Australia. This study traces the changes that have occurred in the reporting of sport in the West Alustralian between 1901 and 1971. This time span has been chosen to cover the period from Federation to the point when sport acquired its own section at the back of the newspaper and sports editor Ted CoIlingwood retired after 32 years in the job. In this seventy year period, January and July of every seventh year are taken as a sample …

The Pulse Of Change : E-Education And Other Reforming Influences On Vocational Education And Training, Robin Stark

Theses: Doctorates and Masters

Reform has been a feature of the Australian Vocational Education and Training (VET) system for more than a decade. The Portfolio tracks the theme of reform through the sub-themes of e-education and globalisation, considering each as a set of changing hegemonic discourses that have redefined VET over the intervening years. Into this mix it is speculated a third sub-theme, that of social capital development, is now emerging. The new social paradigm however is likely to create new uncertainties and expectations in a system that struggles to cope with existing reforms.

The Quest For A Formula : Parliamentary Remuneration In Western Australia, Michael J. Britton

Theses: Doctorates and Masters

The Western Australian Payment of Members Act 1900 was promulgated upon two tenets, namely, that Members of Parliament should be compensated for their services to society and that other Australian colonies were already receiving some form of compensation. The premise stipulated that all people, regardless of economic background should be given an opportunity to fulfil the honourable duly of a Representative. Remuneration in this thesis covers the minimalist advent of Parliamentary Remuneration whereby Mrs were compensated by way of a basic salary to the current multifaceted Parliamentary Remuneration which encompasses various structures, processes and is often overarched by complicated determinative …

Meaning And Emotion In Squaresoft's Final Fantasy X: Re-Theorising Realism And Identification In Video Games, Glen R. Spoors

Theses: Doctorates and Masters

This thesis takes the position that traditional theories of "realism" and "identification" misrepresent the relationships between players and videogames, and that a cross·disciplinary approach is needed. It uses Ed Tan's (1997) and Torben Grodal's (1997) analyses of narrative, cognition, and emotion in film as a basis for interrogating existing research on, and providing a working model of, video gameplay. It develops this model through an extended account of Squaresoft's adventure role-playing game Final Fantasy X (FFX) (2001), whose hybrid narrative and game macrostructures foreground many of the problems associated with video games. The chapters respectively address; existing research on video …

Language Learning Strategies Of Botswana Students : An Exploratory Study, Joel M. Magogwe

Theses: Doctorates and Masters

The purpose of this research is to explore the learning strategies used by Botswana students acquiring English as a second language. It also examines whether the choice of strategies is affected by the factors of different age/level of education, proficiency and gender. The research also explores whether the students’ self-efficacy beliefs correlated with their use of language learning strategies. Specifically this research examined the types of strategies used by primary, secondary and tertiary students. It also examined the types of strategies used by the students deemed by their teachers to have good, fair or poor levels of English proficiency. The …

Fibromyalgia And Bladder Irritability, Carolyn K. Brand

Theses: Doctorates and Masters

Urinary tract sensory symptoms provide an additional symptomatic burden for women with fibromyalgia. The urogenital symptoms of both fibromyalgia and interstitial cystitis have been described as non-infective sensory disorders, suggesting the existence of substantial clinical overlap between the two conditions. Research suggests that although interstitial cystitis has been treated as a specific bladder condition, it may be part of the disorder of central processing of sensory information as seen in fibromyalgia.

The interstitial cystitis symptom index and problem index (ICSI/ICPI) have been used to measure lower urinary tract symptoms and to examine the impact of these symptoms in patients with …

Suburbia : A Postmodern Artistic Investigation And An Examination Of How Postmodern Approaches Can Be Effectively Adopted In The Context Of The New Western Australian Post-Compulsory Visual Arts Course Of Study, Lisa Young

Theses: Doctorates and Masters

In 2007, Western Australia art educators will be required to teach a new post-compulsory visual arts curriculum. This course written in a postmodern context, will need a paradigm shift in approach. As a visual arts educator and a visual artist working in a contemporary context what are valid and effective methods of creatively investigating the postmodern world? How can postmodern themes be taught and strategies employed effectively and with integrity in a visual arts curriculum? What are effective and valid approaches to teaching visual arts in the context of the post-complusory Visual Arts Course of Study?

An Examination Of Facilitators And Inhibitors To Knowledge Sharing In A Policing Environment : Lessons From Intelligence-Led Crime Management Units Of The Western Australia Police Service, Vince Hughes

Theses: Doctorates and Masters

The objective of this research project was to gain an understanding of the inhibitors and facilitators to knowledge sharing within a policing environment. Although it did not begin with the intention of applying interverntions of any kind, in the course of the thesis it became clear that a form of action research was being employed. Initially, I presented my research proposal as a hermeneutic examination of the facilitators and inhibitors to knowledge sharing in the Western Australia Police. However, somewhere along my research journey I realised that rather than me simply collecting and analysing data from and about my colleagues, …

The Use Of Principles And Techniques Derived From Meditation For The Design And Creation Of Co-Participatory Musical Systems, Hannah E. Clemen

Theses: Doctorates and Masters

For this thesis, a detailed study was undertaken to determine whether techniques derived from traditional meditation systems can be applied to "co-participatory" music systems in order to enhance their accessibility, interactivity, and experiential impact, In order to adequately address this subject, a number of investigative steps have been taken. First, a workable list of definitions for what meditation actually is was made by comparing the practices and philosophies of a number of traditional meditation forms. The conclusions derived from this stage of the discussion served to create a definitive "blueprint" for meditation and served as a theoretical foundation for the …

Aspects Of Current English Language Teaching Practices With A Special Focus On Task, Valerie Kollmann

Theses: Doctorates and Masters

This portfolio is written with the intention to explore current English language teaching practices in global as well as Australian contexts, with emphasis on task-based language teaching. As a result of the forces of globalisation, the number of learners involved in English language instruction has increased throughout the world and with it the necessity of language programs that would facilitate instruction in accordance with the needs of the market. Since the task-based language syllabus is founded on needs generated by the learners, there is potential for this language teaching methodology to become the recommended mode of instruction in the future. …
