Design And Analysis Of Optical Layouts For Free Space Optical Switching, Kung-Meng Lo Jan 2002

Design And Analysis Of Optical Layouts For Free Space Optical Switching, Kung-Meng Lo

Theses: Doctorates and Masters

The Intelligent Reconfigurable Optical Switch (IROS) is an N x N optical switch that uses two reflective Liquid Crystal (LC) Spatial Light Modulators (SLM} in a "Z" configuration to steer the incoming beams from the input ports to the designated output ports. Currently, the maximum steering capacity of practical SLM is limited to few degrees. For a dense optical switch, this makes the optical path between the input and output fiber ports relatively long. When a Gaussian beam is switched from an input fiber port to an output fiber port in a long free space interconnection topology, the beam's illumination …


Student Learning And Cognition In Cooperative Small Groups : Towards A Fourth Metaphor Of Human Learning, Scott C. Zehnder Jan 2002

Student Learning And Cognition In Cooperative Small Groups : Towards A Fourth Metaphor Of Human Learning, Scott C. Zehnder

Theses: Doctorates and Masters

Research into the benefits of cooperative learning has focussed most attention onto a social psychological perspective with the result that the putative cognitive benefits of these strategies have not been thoroughly researched and clearly delineated. One consequence of this research focus has been that cooperative learning strategies are not always adopted by teachers and included permanently into their regular classroom practice, thereby possibly denying some students the potential for cognitive gain. This study was conceived originally as an investigation into the claimed cognitive benefits of small-group cooperative learning from a cognitive perspective but the investigation of the cooperative learning literature …


Teachers' Perceptions Of Quality Teaching In Junior Secondary School : Physical Education In Lagos State, Nigeria, Adesulue B. Adegbamigbe Jan 2002

Teachers' Perceptions Of Quality Teaching In Junior Secondary School : Physical Education In Lagos State, Nigeria, Adesulue B. Adegbamigbe

Theses: Doctorates and Masters

This study investigates physical education (PE) teachers' perceptions of quality teaching as related to their teaching activities in junior secondary schools in Nigeria. The study also investigated how the perceived teaching quality of the teachers matched their teaching practices and the feasibility of supporting quality teaching in these schools. The research is underpinned by a conceptual framework, which identified quality teaching as an educational process influenced by the curriculum, teacher effectiveness, teacher reflection and belief systems, and teacher development process designed to enhance students' learning. The study incorporated a descriptive survey and interpretive case study for data collection. A pilot …


Factors Affecting The Bit Error Rate Performance Of The Indoor Radio Propagation Channel For 2.3-2.5 Ghz Frequency Band, Edward A. Walker Jan 2002

Factors Affecting The Bit Error Rate Performance Of The Indoor Radio Propagation Channel For 2.3-2.5 Ghz Frequency Band, Edward A. Walker

Theses: Doctorates and Masters

The use of wireless in buildings based on microwave radio technology has recently become a viable alternative to the traditional wired transmission media. Because of the portable nature of radio transceivers, the need for extensive cabling of buildings with either twisted pair, coaxial, or optical fibre cable is eliminated. This is particularly desirable where high user mobility occurs and existing wiring is not in place, or buildings are heritage in nature and extensive cabling is seen as intrusive. Economic analysis bas also shown that significant labour cost savings can result by using a radio system or a hybrid mix of …


Drama Teaching: Understanding What We Do, Valerie Johnson Jan 2002

Drama Teaching: Understanding What We Do, Valerie Johnson

Theses: Doctorates and Masters

Drama teaching in secondary schools in Western Australia has become an increasingly complex discipline in recent years. This study has considered the work of Drama teachers from the point of view of those practising the discipline, using a phenomenological methodology which allowed the voices of the participants to be heard directly. In the discussion, consideration is given to the way in which these teachers practice the dynamic which is drama, are influenced by the art form of theatre, and deliver the school subject, Drama.


Finding The True Performance Of Australian Managed Funds, Victor Soucik Jan 2002

Finding The True Performance Of Australian Managed Funds, Victor Soucik

Theses: Doctorates and Masters

When making conclusions about the performance of managed funds, it is critical that the framework in which such performance is measured provides an accurate and unbiased environment. In this thesis I search for true performance of the two major classes of funds- equity as well as fixed interest managed funds. Focusing, first on the former class, I examine five measurement models across three risk-free proxies, nine benchmarks proposed by the extant literature (covering conditional and unconditional as well as single and multi factor definitions) and over three independent periods in an effort to identity (in a consistent setting) the most …


Religious Education: Outcomes-Based Integration Across The Primary Curriculum, Paul Longobardi Jan 2002

Religious Education: Outcomes-Based Integration Across The Primary Curriculum, Paul Longobardi

Theses: Doctorates and Masters

This study shows that the integrity of curriculum in Catholic Schools can be demonstrated through an integrated curriculum, with Religious Education (R.E.) as the primary focus, centre point and generator of learning experiences across all subjects or Key Learning Areas (K.L.As). The contemporary, Catholic nature of curriculum is able to be developed via an outcomes-based approach that integrates R.E. with other Key Learning Areas. The "Integrated Religious Education Outcomes Approach" represents a personal belief of the author, developed as a classroom teacher in five Catholic schools and a member of three schools' Executive. The response to this belief is the …


The Computation Choices Made By Students In Years 5 To 7, Paul Swan Jan 2002

The Computation Choices Made By Students In Years 5 To 7, Paul Swan

Theses: Doctorates and Masters

This study was designed to explore the computation choices made by 78 students in Years 5 to 7. The ability to choose and use a repertoire of computation methods is an important goal of mathematics education. While one might expect to find a great deal of research outlining the computation choices students make and why they make them, this was not the case; and as such it was decided to explore what computation choices students make and why they make them.

The Development Of Personal, Analogous And Universal Thinking Through In-Role Drama : A Case Study, Sarah Riddoch

Theses: Doctorates and Masters

The main purpose of this study was to investigate the development of the problem-solving skills of eleven year olds in a Western Australian Primary school when the teacher and the children were in-role within the drama. The teacher, as teacher in-role, and the students role-played a variety of situations in which effective problem-solving skills were used. As the study progressed the nature of the children's use of symbol and metaphor became an important issue. In the first session the teacher in-role as the Mayor of a small town informed the children in-role as the town council that an alien spacecraft …


Students' Needs And Attitudes: Efl Education In Japanese High Schools, Michelle Perche Jan 2002

Students' Needs And Attitudes: Efl Education In Japanese High Schools, Michelle Perche

Theses: Doctorates and Masters

Much of the literature on EFL education in Japan describes a system that is fraught with problems. Over the last decade the Japanese Education Ministry (Monbusho) has introduced a number of reforms and introduced some new EFL courses into Japanese schools. The stated aim of the new courses has been to focus on the development of students' communicative abilities in English. However, the effectiveness of these reforms has been questioned particularly at the senior high school level. According to a number of commentators, difficulties occur because of a back wash effect of the university entrance examinations. Others criticise the teachers …


Modulation Classification Of Digital Communication Signals, Visalakshi S. Ramakonar Jan 2002

Modulation Classification Of Digital Communication Signals, Visalakshi S. Ramakonar

Theses: Doctorates and Masters

Modulation classification of digital communications signals plays an important role in both military and civilian sectors. It has the potential of replacing several receivers with one universal receiver. An automatic modulation classifier can be defined as a system that automatically identifies the modulation type of the received signal given that the signal exists and its parameters lie in a known range. This thesis addresses the need for a universal modulation classifier capable of classifying a comprehensive list of digital modulation schemes. Two classification approaches are presented: a decision-theoretic (DT) approach and a neural network (NN) approach. First classifiers are introduced …


Conceptual-Associative System In Aboriginal English : A Study Of Aboriginal Children Attending Primary Schools In Metropolitan Perth, Farzad Sharifian Jan 2002

Conceptual-Associative System In Aboriginal English : A Study Of Aboriginal Children Attending Primary Schools In Metropolitan Perth, Farzad Sharifian

Theses: Doctorates and Masters

National measures of achievement among Australian school children suggest that Aboriginal students, considered as a group, are those most likely to end their schooling without achieving minimal acceptable levels of literacy and numeracy. In view of the fact that many Aboriginal students dwell in metropolitan areas and speak English as a first language, many educators have been unconvinced that linguistic and cultural difference have been significant factors in this underachievement. This study explores the possibility that, despite intensive exposure to non-Aboriginal society, Aboriginal students in metropolitan Perth may maintain, through a distinctive variety of English, distinctive conceptualisation which may help …

Proposed Statement On Auditing Standards : Auditing Fair Value Measurements And Disclosures;Auditing Fair Value Measurements And Disclosuses; Exposure Draft (American Institute Of Certified Public Accountants), 2002, June 28, American Institute Of Certified Public Accountants. Auditing Standards Board

Exposure Drafts, Comment Letters, and Statements of Position

In recent years, generally accepted accounting principles (GAAP) have required entities to significantly increase the use of fair value for measuring, presenting, and disclosing in their financial statements assets, liabilities, and specific components of equity. The business environment and GAAP that apply to the transactions and events in that environment have become more complex. Along with that complexity and the increased use of fair value measurements and disclosures comes an increasing acknowledgment of the importance of fair values in the financial reporting process. The ASB believes that a Statement on Auditing Standards (SAS) providing overall guidance on auditing considerations relating …

Vertex-Unfoldings Of Simplicial Manifolds, Erik D. Demaine, David Eppstein, Jeff Erickson, George W. Hart, Joseph O'Rourke Jan 2002

Vertex-Unfoldings Of Simplicial Manifolds, Erik D. Demaine, David Eppstein, Jeff Erickson, George W. Hart, Joseph O'Rourke

Computer Science: Faculty Publications

We present an algorithm to unfold any triangulated 2-manifold (in particular, any simplicial polyhedron) into a non-overlapping, connected planar layout in linear time. The manifold is cut only along its edges. The resulting layout is connected, but it may have a disconnected interior; the triangles are connected at vertices, but not necessarily joined along edges. We extend our algorithm to establish a similar result for simplicial manifolds of arbitrary dimension.


A Case Study Of A Child Presenting Academic And On Task Difficulties, Eric Stephen Weichers Jan 2002

A Case Study Of A Child Presenting Academic And On Task Difficulties, Eric Stephen Weichers

A special education evaluation was conducted that included the procedures of reviewing the student's records, interviewing those of consequence to the evaluation, classroom observations of the student's behavior, and testing of skills. The testing procedures included nationally normed standardized tests, curriculum based assessment, permanent product review, informal reading inventory scores, and an intelligence test. …


Effect Of Tio₂-Mediated Photocatalytic Degradation On The Toxicity Of Orange Ii, Arnaud Eric Nicolas Goutard Jan 2002

Effect Of Tio₂-Mediated Photocatalytic Degradation On The Toxicity Of Orange Ii, Arnaud Eric Nicolas Goutard

Dissertations and Theses @ UNI

C.I. Acid Orange 7 (15510) is the sodium salt of p-[(2-hydroxy-1-naphtalenyl)azo] benzenesulfonic acid. This azo dye is commonly known as Orange II and has been used to dye soaps, shoes, wood and paper (Ramchandani et al., 1994). In the United States and Europe, this dye is not allowed in foodstuffs. The purpose of this study is to investigate the efficiency of a TiO2-mediated photocatalytic oxidation process to degrade Orange II and to determine if Orange II is cytotoxic to certain types of cells. The role of UV radiation and TiO2 particles were examined, as well as the importance of oxygen …

Proportionality Of Financial Ratios And Prediction Of The Company Performance Of Stocks In The Kuala Lumpur Stock Exchange, Siew Foong Yeong Jan 2002

Proportionality Of Financial Ratios And Prediction Of The Company Performance Of Stocks In The Kuala Lumpur Stock Exchange, Siew Foong Yeong

Student Works (2000-2009)

This paper analyses the proportionality assumption of financial ratios generated from counters selected from Kuala Lumpur Stock Exchange (KLSE), Malaysia. Proportionality assumption in financial ratios is essential in financial statement analysis as it allows us to compare ratios across firms of different sizes. Thus, it also allows us to use financial ratio to further our analysis into company performance prediction. Earning Per Share (EPS) and Revenue Per Share (RPS) are among the tools in measuring company performance. OLS regression analysis with enter-all-variables and stepwise methods will be used to forecast company performance, where this year (n) financial ratios will be …

Topological Sweep In Degenerate Cases, Eynat Rafalin, Diane Souvaine, Ileana Streinu Jan 2002

Topological Sweep In Degenerate Cases, Eynat Rafalin, Diane Souvaine, Ileana Streinu

Computer Science: Faculty Publications

Topological sweep can contribute to efficient implementations of various algorithms for data analysis. Real data, however, has degeneracies. The modification of the topological sweep algorithm presented here handles degenerate cases such as parallel or multiply concurrent lines without requiring numerical perturbations to achieve general position. Our method maintains the 0(n2) and 0(n) time and space complexities of the original algorithm, and is robust and easy to implement. We present experimental results.

Measured Interpretation: Introducing The Method Of Correspondence Analysis To Legal Studies, Bernard E. Harcourt Jan 2002

Measured Interpretation: Introducing The Method Of Correspondence Analysis To Legal Studies, Bernard E. Harcourt

Faculty Scholarship

Professor Harcourt develops and advocates a method to more rigorously measure and evaluate how qualitative “social meaning” variables relate to legal practices and public policies. The method integrates in-depth qualitative interviews with an experimental free associational component, map analysis of the interviews, and a methodology, correspondence analysis, that remains little known in the United States despite its acceptance in other parts of the world. Correspondence analysis, according to Professor Harcourt, is a tool that allows researchers to visually represent the relationship between structures of social meaning and the contexts and practices within which they are embedded. This method opens up …
