Terminal Sliding Mode Control For Rigid Robotic Manipulators With Uncertain Dynamics, Nicola Ritter Jan 1996

Terminal Sliding Mode Control For Rigid Robotic Manipulators With Uncertain Dynamics, Nicola Ritter

Theses: Doctorates and Masters

This thesis presents two new adaptive control laws that use the terminal sliding mode technique for the tracking problem of rigid robotic manipulators with non-linearities, dynamic couplings and uncertain parameters. The first law provides a robust scheme which uses several properties of rigid robotic mauipulators and adaptively adjusts seven uncertain parameter bounds. The law ensures finite time error convergence to the system origin and is simple to implement The second law treats the manipulator as a partially known system. The known dynamics are used to build a nominal control law and the effects of unknown system dynamics arc compensated for …


Influence Of Adjacent Seagrass On The Fish Assemblages Off Sandy Beaches, Matthew A. Vanderklift Jan 1996

Influence Of Adjacent Seagrass On The Fish Assemblages Off Sandy Beaches, Matthew A. Vanderklift

Theses: Doctorates and Masters

As we attempt to maintain marine biodiversity mainly by focussing on habitats, we need to understand how marine biodiversity is affected by seagrass loss. Although managers and researchers widely acknowledge that habitat loss results in changes to marine biodiversity, quantitative knowledge of these changes is generally poor. In this study, fish assemblages (as one component of the biodiversity of sandy beaches) were examined in Cockburn Sound, Western Australia, to assess patterns that may be related to presence or absence of adjacent seagrass beds, If consistent patterns are evident, they may enable predictions regarding the effects of seagrass loss on the …

This study examines the incentives of Australian listed mineral mining companies within the stakeholder theoretical framework to disclose socially responsible information in their corporate annual report. The three dimensions of the stakeholder theory were empirically tested to explain the association of a social disclosure model comprising categories of social disclosure for environment, energy, product and services, human resources and community involvement, with nine firm-specific characteristics. The sample of 179 Australian listed mineral mining companies for the financial year ending 1994 was obtained by personal contact. The extent of social disclosure was measured by a dichotomous index against the social disclosure …


An Adaptive Fuzzy Logic Controller For Intelligent Networking And Control, Irshad Nainar Jan 1996

An Adaptive Fuzzy Logic Controller For Intelligent Networking And Control, Irshad Nainar

Theses: Doctorates and Masters

In this thesis, we present a fuzzy logic control scheme to regulate the flow of traffic approaching a set of intersections. An adaptive Fuzzy Logic Traffic Controller (FLTC) is used to adjust the green phase split of the north-south and east-west approaches of a set of traffic signals based on the actual traffic approaching the intersection. Each intersection is coordinated with its neighbouring intersections by adjusting the offset of the local intersection. The offset is adjusted by a local fuzzy logic controller loacted at each intersection. A new fuzzy control scheme, using a supervisory Fuzzy Logic Controller, is also proposed …

Codependent Concerns Among Nurses, Virgina S. Besomo Jan 1996

Codependent Concerns Among Nurses, Virgina S. Besomo

Theses: Doctorates and Masters

Codependency is a complex dysfunctional behaviour pattern characterised by a dependence upon external reference points for ways of being. An abundance of nursing literature claims that codependency is (a) a problem among nurses, (b) related to the demands of the profession, and that (c) codependent nurses eventually suffer disillusionment and burnout. The purpose of this descriptive study was to examine the severity of codependent concerns among Western Australian registered nurses in order to direct a response to these claims. A random sample of 1000 West Australian registered nurses were mailed surveys with an option for them to respond anonymously by …

The 'Stunned' And The 'Stymied' : The P.O.W. Experience In The History Of The 2/11th Infantry Battalion, 1939-1945, Mary R. Watt

Theses: Doctorates and Masters

Stimulated by a pronouncement of Joan Beaumont that prisoners of war are a neglected subject of historical inquiry this thesis undertakes an empirical and analytical study concerning this topic. Within the context of the prisoner of war experience in the history of the 2/11th Infantry Battalion during the Second World War, it puts a case for including non-operational strands of warfare in the body of Australian official military history. To facilitate this contention the study attempts to show the reasons for which historians might study the scope and range of the prisoner of war experience. Apart from describing the context …

Earnings Management And Accounting Choices In Initial Public Offerings : Evidence From Indonesia, Tatang A. Gumanti Jan 1996

Earnings Management And Accounting Choices In Initial Public Offerings : Evidence From Indonesia, Tatang A. Gumanti

Theses: Doctorates and Masters

Information asymmetry about the value of the firm making initial public Offering and the potential investors exists. This thesis investigates whether issuers of initial public affairs (IPOs) use accounting discretion to increase the reported earnings through the choice of accounting methods. Anecdotal evidence •suggests that accounting numbers are used in the pricing of IPO. Further, there is an economic incentive for issuers of IPOs to sell the offering shares at the highest possible price which in tum increases their proceeds and thus their wealth. This suggests a prediction that, immediately prior to the offering, issuers exercise accounting discretion to increase …


Use Of Section 20 Of The Education Act 1928: The Study Of A Contemporary Issue Using The Narrative Form, Janette R. Gray Jan 1996

Use Of Section 20 Of The Education Act 1928: The Study Of A Contemporary Issue Using The Narrative Form, Janette R. Gray

Theses: Doctorates and Masters

There is a growing acceptance in the social sciences that in the telling and reading of a story a form of truth can be developed. This 'truth' will be dependent on the reader actively constructing knowledge from constant reflection and modification using cultural (bounded) knowledge as a basis for comparison. Typically the narrative form employs the use of evocative, contextualised language to create implicit meaning, a plot based on some form of conflict within a temporal framework, and the use of multiple voices and genres. Generalisation from the sequence of events subsumed in the plot is assisted by the effective …


Perceptions Of Financial Counselling In Western Australia, Natalie Dall Jan 1996

Perceptions Of Financial Counselling In Western Australia, Natalie Dall

Theses: Doctorates and Masters

The development of financial counselling in Australia during the past decade has been complex and fragmented. Financial counselling and rural counselling services within Western Australia are funded from a range of government, non-government and church based groups. This has contributed to problems in the identification of basic definitions of the need for services, the role of the financial counsellor and service models or functions. The failure to define the role of the financial counsellor and the needs to be addressed by financial counselling services, "appears to be the most important historic weakness in the field." (Wyse et al., 1990, p.2). …

Users And Accounting Information Preferences Of Government Department Financial Reports, Helen R. Mignot Jan 1996

Users And Accounting Information Preferences Of Government Department Financial Reports, Helen R. Mignot

Theses: Doctorates and Masters

The introduction of an accounting standard requiring government departments to replace fund-type, cash-based accounting statements with business-type, accrual based accounting statements has led to criticism that business-type, general purpose financial statements do not take account of the information requirements of major users. Such criticism echoes a long standing debate in which the users of public sector financial statements and their informational requirements are analysed in competing models. One view suggests that there are many users with homogeneous informational needs, who can be classified into a few broad groups. The other view maintains that there are few users who have differential …

A Cross-Cultural Study On Complaint Letters : Australian And Korean, Y. R. Kim Jan 1996

A Cross-Cultural Study On Complaint Letters : Australian And Korean, Y. R. Kim

Theses: Doctorates and Masters

The aim of the study is to examine the cross-cultural features of Australian and Korean complaint letters. The point of view adopted is that cultural barriers generate difficulties to producing efficient and successful intercultural communication in addition to linguistic barriers. Although the concept of complaint letters is the same in the two countries, there are difficulties when Australians and Koreans attempt to communicate with the other culture. Firstly the study will explore the validating of the concepts of Korean's four-unit structure (Ki-Sung-Chen-Kyul) and the three unit structure typical of western letter writing (Introduction-Body-Conclusion), and contrast the structures. It posits that …

A Search Tool To Enhance The Selection And Utilisation Of Reusable Software Modules Within The Object-Oriented Paradigm, Robert H. Cross

Theses: Doctorates and Masters

The affinity for reuse within the object-oriented paradigm may enable high levels of productivity; however, gains will become realisable only if a systems developer has access to tools which aid in the selection of classes. A method for object-oriented analysis and design is detailed and its process is assisted by an object-oriented search tool based on reference and corporate library technology. The search tool contributes to the determination of suitable existing inheritable classes and an explanation of its construction and use is included. A practical demonstration of the method, using the search tool, is elaborated. The thesis demonstrates that text …


Representations Of Law In Popular Culture: Knowledge Constructions, Media Deconstructions, Virginia Rivalland Jan 1996

Representations Of Law In Popular Culture: Knowledge Constructions, Media Deconstructions, Virginia Rivalland

Theses: Doctorates and Masters

This thesis investigates law and analyses its representations in popular culture. Law is a powerful institution within western society with a regulatory role that is supported by a range of complementary discourses that accord with society's dominant cultural values. This thesis proposes that while such institutional hegemony is never stable as there is always an expectation of challenge or resistance, law is currently experiencing a series of challenges on numerous fronts. Legal commentators themselves acknowledge that law now faces a ‘crisis of confidence' that may affect its status and impact on its power to control and regulate. Media are cultural …


The Interplay Of Formal And Informal Rule Systems In Government Primary Schools, Raymond Knight Jan 1996
