The Design And Analysis Of Benchmark Experiments, Torsten Hothorn, Friedrich Leisch, Achim Zeileis, Kurt Hornik

Faculty of Commerce - Papers (Archive)

The assessment of the performance of learners by means of benchmark experiments is an established exercise. In practice, benchmark studies are a tool to compare the performance of several competing algorithms for a certain learning problem. Cross-validation or resampling techniques are commonly used to derive point estimates of the performances which are compared to identify algorithms with good properties. For several benchmarking problems, test procedures taking the variability of those point estimates into account have been suggested. Most of the recently proposed inference procedures are based on special variance estimators for the cross-validated performance. We introduce a theoretical framework for …

Ux Ret And Cn Hyi: Hipparcos Photometry Analysis, Surinder S. Wadhwa, William J. Zealey

Faculty of Health and Behavioural Sciences - Papers (Archive)

We present an analysis of the Hipparcos photometry of the contact binary systems UX Ret and CN Hyi. The Wilson-Devinney code is employed to model the V band light curve for several fixed values of the mass ratio. From the quality-of-fit of the different solutions a final solution is derived for each system. Absolute values of the system are derived using the parallax data from the Hipparcos catalog. Analysis of the V band photometry of two stars (EL Aqr and FN Cam) with spectroscopically known mass ratios is also provided as a validation for the methods adopted for this study.

Applying Formal Concept Analysis To Semantic File Systems Leveraging Wordnet, Benjamin Martin, Peter W. Eklund

Faculty of Health and Behavioural Sciences - Papers (Archive)

Formal Concept Analysis can be used to obtain both a natural clustering of documents along with a partial ordering over those clusters. The application of Formal Concept Analysis requires input to be in the form of a binary relation between two sets. This paper investigates how a semantic filesystem can be used to generate such binary relations. The manner in which the binary relation is generated impacts how useful the result of Formal Concept Analysis will be for navigating one’s filesystem.

Dynamic Schema Navigation Using Formal Concept Analysis, Jon R. Ducrou, Bastian Wormuth, Peter W. Eklund

Faculty of Commerce - Papers (Archive)

This paper introduces a framework for relational schema navigation via a Web-based browser application that uses Formal Concept Analysis as the metaphor for analysis and interaction. Formal Concept Analysis is a rich framework for data analysis based on applied lattice and order theory. The application we develop, D-SIFT, is intended to provide users untrained in Formal Concept Analysis with practical and intuitive access to the core functionality of Formal Concept Analysis for the purpose of exploring relational database schema. D-SIFT is a Web-based information systems architecture that supports natural search processes over a preexisting database schema and its content.

A Mission-Centric Approach To Financial Ratio Analysis In The Nonprofit Sector, Anne Abraham

Faculty of Commerce - Papers (Archive)

Nonprofit organisations (NPOs) are melting pots combining mission, members and money. Given that the mission of a nonprofit organisation is the reason for its existence, it is appropriate to focus on financial resources in their association with mission and with the individuals who are served by that mission [1] [2] [3]. Measurement of financial performance by ratio analysis helps identify organisational strengths and weaknesses by detecting financial anomalies and focusing attention on issues of organisational importance [4].

Questions have been raised that relate the performance of NPOs to their fmancial resources, their mission and their membership. Addressing these questions is …

Managing Mission, Members And Money: A Financial Analysis Model For The Nonprofit Sector, Anne Abraham

Faculty of Commerce - Papers (Archive)

Nonprofit organisations (NPOs) are melting pots combining mission, members and money. Given that the mission of a nonprofit organisation is the reason for its existence, it is appropriate to focus on financial resources in their association with mission and with the individuals who are served by that mission (Parker 2003; Wooten et al 2003; Colby and Rubin 2005). Measurement of financial perfonnance by ratio analysis helps identify organisational strengths and weaknesses by detecting financial anomalies and focusing attention on issues of organisational importance (Glynn et al 2003).

Questions have been raised that relate the perfonnance of NPOs to their financial …

Restructuring Help Systems Using Formal Concept Analysis, Peter W. Eklund, Bastian Wormuth

Faculty of Commerce - Papers (Archive)

This paper extends standard help system technology to demonstrate the suitability of Formal Concept Analysis in displaying, searching and navigating help content. The paper introduces a method for building suitable scales directly from the help system index by computing a keyword extension set. The keyword extension technique is generalisable in any document collection where a hand-crafted index of terms is available.

Confirmation Of The Structure Of Oxystemokerrin By Single Crystal X-Ray Structural Analysis And A Proposed Biosynthesis, Pitchaya Mungkornasawakul, Hayden Matthews, Alison T. Ung, Stephen G. Pyne, Araya Jatisatienr, Wilford Lie, Brian W. Skelton, Allan H. White

Faculty of Science - Papers (Archive)

The crystal structure of the pentacyclic Stemona alkaloid oxystemokerrin (2), isolated from the roots of Stemona kerrii, is reported, confirming the structure proposed for this compound in a contemporaneous spectroscopic study. This compound is a diastereomer of stemocurtisinol (3), whose structure we have recently reported from S. curtisii, also confirmed by a single-crystal X-ray study. These alkaloids have opposite configurations at C-4 and C-19. A possible biosynthetic pathway for the biosynthesis of 2 and 3 is proposed.

Doing Discourse Analysis, Gordon R. Waitt

Faculty of Science - Papers (Archive)

My hope in writing this chapter is to generate enthusiasm for geographical research employing discourse analysis. My intention is to provide some advice on doing discourse analysis to facilitale the design of research. I first outline why some geographers have been inspired by this approach. I suggest how Foucauldian discourse analysis is a break from other critical methods applied to textual analysis, including content analysis, semiology, and iconography. The theoretical underpinnings of the method provided by Michel Foucault, a French poststructuralist philosopher, is a key source of difference. I therefore condense Michel Foucault's contribution to discourse analysis by sketching out …

Basing Economy On Materiality: An Analysis Of Sydney's Freight Flows, Phillip O'Neill, Pauline M. Mcguirk, Frank Stilwell, Dick Bryan

Faculty of Social Sciences - Papers (Archive)

This paper is part of a systematic examination by the authors of Sydney's changing political economy within its largely self-imposed globalisation agenda. This part seeks to unravel the changing nature of Sydney's material connections across the Sydney basin economy and with other places. The analysis is based on novel uses of GIS-based software and its application to freight flow data. There are employed to describe and delineate the composition, intensity and direction of materials flows arising from the functioning of the Sydney economy. Two questions are explored. First, we seek to expose the global city metaphor as narrowly defining what …

Informing Curriculum Design Using Genre Analysis: A Study Of Three Genres In Japanese, Elizabeth A. Thomson

Faculty of Arts - Papers (Archive)

The notion that texts in Japanese can be described in terms of text type or genre is not a new or novel approach. However, such descriptions are not common. This paper presents a description of three genres in Japanese: the factual news commentary, the hard news story and the soft news story. The descriptions have been informed by systemic functional linguistics, in particular by work 011 the system of THEME (Halliday 1994, Martin 1993, Mathiessen 1995), thematic patterns of progression (Danes 1974, Fries 1983, Ghadessy /995) and generic structure potential (GSP) (Hasan 1996). The GSP representation o/the genres enables a …

Bayesian Analysis For Penalized Spline Regression Using Winbugs, Ciprian Crainiceanu, David Ruppert, M. P. Wand

Faculty of Engineering and Information Sciences - Papers: Part A

Penalized splines can be viewed as BLUPs in a mixed model framework, which allows the use of mixed model software for smoothing. Thus, software originally developed for Bayesian analysis of mixed models can be used for penalized spline regression. Bayesian inference for nonparametric models enjoys the flexibility of nonparametric models and the exact inference provided by the Bayesian inferential machinery. This paper provides a simple, yet comprehensive, set of programs for the implementation of nonparametric Bayesian analysis in WinBUGS. Good mixing properties of the MCMC chains are obtained by using low-rank thin-plate splines, while simulation times per iteration are reduced …

Quasi-Static Analysis Of Defected Ground Structure, Nemai C. Karmakar, Sushim Mukul Roy, Isaac Balbin, Gerhard F. Swiegers

Faculty of Science - Papers (Archive)

A quasi-static equivalent circuit model of a dumbbell shaped defected ground structure (DGS) is developed. The equivalent circuit model is derived from the equivalent inductance and capacitance developed due to the perturbed returned current path on the ground and the narrow gap, respectively. The theory is validated against the commercial full-wave solver CST Microwave Studio. Finally, the calculated results are compared with the measured results. Good agreement between the theory, the commercially available numerical analyses and the experimental results validates the developed theoretical model.
