A Comparison Of The Effects Of Reading From A Vdu And From Paper As Measured In Terms Of Reading Speed And Comprehension, Elizabeth Payumo Jan 1992

A Comparison Of The Effects Of Reading From A Vdu And From Paper As Measured In Terms Of Reading Speed And Comprehension, Elizabeth Payumo

Theses: Doctorates and Masters

This study investigates the legibility and visual effects of eight combinations of font and colour on VDU and two different fonts on paper. Forty subjects, sixteen females and twenty-four males, were exposed to three of the ten different conditions, one in each of the set of readings, on either VDU or paper. They were asked to read different sets of stories in each condition on different days where each condition lasted for approximately two hours. Reading speed and comprehension scores were measured in every story read in the set of stories. The change of mood and physical symptoms states of …

An Analysis Of The Monitored Electronic Alarm Activations In The Perth Metropolitan Area, Lynnette M. Bloom, James M. Cross, David Mcdougall Jan 1991

An Analysis Of The Monitored Electronic Alarm Activations In The Perth Metropolitan Area, Lynnette M. Bloom, James M. Cross, David Mcdougall

Research outputs pre 2011

This study as indicated in [7] was carried out under the auspices of Edith Cowan University's Institute of Security and Applied Technology and had the support of the Western Australian Police and the Perth-based Central Monitoring Agencies. The data analysed was obtained essentially from Police records, backed up by data from two of Perth's larger security companies, and consists of all the monitored alarms in the Perth Metropolitan Area which were attended by the police in the months of May and September 1989.In our consideration of the frequency of alarms by time of day and day of week, and the …

An Examination And Analysis Of The Boltzmann Machine, Its Mean Field Theory Approximation, And Learning Algorithm, Vincent Clive Phillips Jan 1991

An Examination And Analysis Of The Boltzmann Machine, Its Mean Field Theory Approximation, And Learning Algorithm, Vincent Clive Phillips

Theses : Honours

It is currently believed that artificial neural network models may form the basis for inte1ligent computational devices. The Boltzmann Machine belongs to the class of recursive artificial neural networks and uses a supervised learning algorithm to learn the mapping between input vectors and desired outputs. This study examines the parameters that influence the performance of the Boltzmann Machine learning algorithm. Improving the performance of the algorithm through the use of a naïve mean field theory approximation is also examined. The study was initiated to examine the hypothesis that the Boltzmann Machine learning algorithm, when used with the mean field approximation, …

Three Denerations Of Dbms, Maria Skiba Jan 1991

Three Denerations Of Dbms, Maria Skiba

Theses : Honours

This paper describes the evolution of data base technology from early computing to the sophisticated systems of today. It presents an overview of the most popular data base management systems architectures such as hierarchical, network, relational and object-oriented. The last section of this paper presents a view of the factors that will influence the future of data base technology.

An Analysis And Implementation Of Linear Derivation Strategies, Winston M. Tabada Jan 1991

An Analysis And Implementation Of Linear Derivation Strategies, Winston M. Tabada

Theses: Doctorates and Masters

This study examines the efficacy of six linear derivation strategies: (i) s-linear resolution, (ii) the ME procedure; (iii) t-linear resolution, (iv) SL -resolution, (v) the GC procedure, and (vi) SLM. The analysis is focused on the different restrictions and operations employed in each derivation strategy. The selection function, restrictive ancestor resolution, compulsory ancestor resolution on literals having atoms which are or become identical, compulsory merging operations, reuse of truncated literals, spreading of FALSE literals, no-tautologies resection, no two non-B-literals having identical atoms restriction, and the use of semantic information to trim irrelevant derivations from the search tree are the major …

Digital Image Processing Using Mathematical Morphology, Andrew Mehnert Jan 1990

Digital Image Processing Using Mathematical Morphology, Andrew Mehnert

Theses : Honours

This dissertation is a natural extension of my undergraduate research project entitled, "Digital Image Processing”. Whilst my undergraduate project dealt with a number of classical digital image filtering techniques such as spatial convolution and frequency domain filtering via the Fourier transform, this dissertation focuses on an alternative approach employing Mathematical Morphology. In contrast to classical filtering techniques, which often geometrically distort the original image, morphological operations, used sensibly, essentially preserve shape and geometry. Mathematical morphology therefore lends itself to image processing applications requiring the identification of objects and object features within an image. Herein basic morphological operations are developed, firstly …

The Development Of An Expert System For The Diagnosis Of Diseases In Fibre And Dairy Goats, Tim S. Roberts Jan 1990

The Development Of An Expert System For The Diagnosis Of Diseases In Fibre And Dairy Goats, Tim S. Roberts

Theses: Doctorates and Masters

This thesis details the development of an expert system for the diagnosis of diseases in fibre and dairy goats. Divided into five sections, five appendices, and a bibliography, this thesis centres on the methods used to build the expert system: the decisions taken at the outset of, and during the course of, development; some of the problems encountered, and the solutions to those problems. A detailed appraisal is made of the development process and suggestions are made for future developments over similar domains (for example, the diagnosis of diseases in animals other than goats). Much emphasis is placed on three …

An Investigation Into The Use Of Prolog For Chinese-English Translation, J. W. L. Millar Jan 1989

An Investigation Into The Use Of Prolog For Chinese-English Translation, J. W. L. Millar

Research outputs pre 2011

In order to undertake machine translation from Chinese to English, it is necessary to accomplish three tasks. Firstly, the Chinese characters need to be handled on the computer system in use - in this case an IBM PC/XT. Secondly, the grammar for the language has to be represented and here Prolog has been used with a Definite Clause Grammar. Finally, the lexicon must be stored in a manner that facilitates efficient retrieval. Arity Prolog provides a hash table that achieves this task. This report describes the current state of a project aimed at producing a Chinese English machine translation system.
