Robust extended kalman filter applied to location tracking and trajectory prediction for PCS networks

Provisioning of real-time multimedia sessions over wireless cellular network poses unique challenges due to frequent handoff and rerouting of a connection. For this reason, the wireless networks with cellular architecture require efficient user mobility estimation and prediction. This paper proposes using robust extended Kalman filter (REKF) as a location heading altitude estimator of mobile user for next cell prediction in order to improve the connection reliability and bandwidth efficiency of the underlying system. Through analysis we demonstrate that our algorithm reduces the system complexity (compared to existing approach using pattern matching and Kalman filter) as it requires only two base station measurements or only the measurement from the closest base station. Further, the technique is robust against system uncertainties due to inherent deterministic nature in the mobility model and more effective in comparison with the standard Kalman filter.

Robust control applied to metal spraying for rapid tooling

The spray forming process is a novel method of rapidly manufacturing tools and dies for stamping and injection operations. The process sprays molten tool steel from a set of arc spray guns onto a ceramic former to build up a thick steel shell. The volumetric contraction that occurs as the steel cools is offset by a volumetric expansion taking place within the sprayed steel, which allows the dimensional accurate tools to be produced. To ensure that the required phase transformation takes place, the temperature of the steel is regulated during spraying. The sprayed metal acts both as a source of mass and a source of heat and by adjusting the rate at which metal is sprayed; the surface temperature profile over the surface of the steel can be controlled. The temperature profile is measured using a thermal imaging camera and regulated by adjusting the rate at which the guns spray the steel. Because the temperature is regulated by adjusting the feed rate to an actuator that is moving over the surface, this is an example of mobile control, which is a class of distributed parameter control. The dynamic system has been controlled using a PI controller before. The paper describes the application of H∞ tracking type controller as the desire was for the average temperature to follow a desired profile. A study on the controllability of the underlying system was aimed at.

A technology of study applied in marketing education and supported by self-determination theory

The aim of this study is to assess whether universities are meeting the needs of marketing students in their specific university function of providing knowledge and knowledge processes. This viewpoint is not meant to overlook the university role as a civilizing agent in a constant search for truth (McKenna 2001), but the focus for this study (based as it is in a Faculty of Business and Law) is toward graduates entering the corporate world. Therefore, graduates with suitable discipline knowledge and reasoning skills, in this context, must be able to meet the needs of the corporate marketing sector. Extending this backward to the role of the university, this study is by default seeking to establish if universities are meeting the needs of the corporate sector. A comparison is made between marketing classes using a specific technology of study called an autarchic system, and those classes not using this method. As part of this analysis the study investigates the application of self-determination theory and psychological needs satisfaction. The basic needs scale, comprising of two constructs; Control and Caring was adapted and used to evaluate students' perception of subjects using autarchic study system and those not utilising this methodology.

Re-engaging young people through applied learning pedagogy

The Victorian Certificate of Applied Learning (VCAL) was developed as an innovative response to the changing context post-compulsory schooling in Australia. By combining ‘hands-on’ learning approaches with the traditions of adult learning, the VCAL seeks to cater for the learning temperaments and employment pathways of post-compulsory students who are less likely to remain at school to complete a more traditional Victorian Certificate of Education (VCE). This paper draws on my doctoral research into the schooling experience of VCAL students to explore the irony in using adult and work-based learning principles that underpin applied learning pedagogy as a strategy to reengage students frequently considered by schools to be ‘at risk’. It argues that traditional contentdriven and transmissive approaches result in some students being defined ‘at risk’ because of their failure to accept as legitimate traditional school-based modes of learning. It is proposed that teachers in secondary schools require a deeper understanding of applied learning principles and teaching strategies in order to cater for the increasing numbers of applied learning students in the post-compulsory years of secondary schools. It is argued that such an understanding is also critical to avoid many of such students being incorrectly labelled ‘at risk’.

Exploring the challenge of applied learning reform

Post compulsory education in Australia has changed significantly since the early 1990s. For many young people in their later years of schooling, learning now involves a blending of experiences derived from education and training institutions once historically separated and defined by distinctly different approaches to pedagogy and assessment. It is also increasingly common for students to include formalised workbased learning arrangements in their learning program, adding further to the students’ experiences of learning and exposure to different learning contexts. Added to this new mosaic of learning experiences, increased participation rates in schooling have contributed to greater diversity in post compulsory students’ learning temperaments. This paper draws on five case studies to explore the new pedagogical challenges presented by these students’ exposure to different systems of learning and examines the emergence of applied learning in Victoria as a pedagogical response to these challenges. It proposes that effective pedagogical change aiming to address these challenges must overcome the tendency to be marginalised in schools and labelled as an alternative approach to learning. The paper concludes by exploring the possible future of applied learning emerging from the current context of pedagogical change.

What is applied learning? : exploring understandings of applied learning amongst beginning teachers

Deakin University, Geelong initiated a Graduate Diploma of Applied Learning in 2005. At the end of this year we interviewed selected students in order to gather data on their experience of the new course. The concept of Applied Learning is often not well theorised and one result of this is that gaining consensus about what this might mean is often difficult. The students we interviewed came from quite diverse backgrounds and workplace experiences but nevertheless had similar views about what this concept means in practice and were able to clearly articulate examples of Applied Learning in a range of settings. This paper examines their insights in the light of some theoretical perspectives on Applied Learning and also discusses some of the difficulties experienced by these students when they try to apply new ways of teaching and learning in school settings.

Grounded theory as foundations for methods in applied ontology

Research into domain specific ontologies is difficult to treat empirically. This is because it is difficult to ground domain ontology while simultaneously being true to its guiding philosophy or theory. Further, ontology generation is often introspective and reflective or relies on experts for ontology generation. Even those relying on expert generation lack rigour and tend to be more ad-hoc. We ask how Grounded Theory can be used to generate domain specific ontologies where appropriate high level theory and suitable textual data sources are available. We are undertaking generation of a domain ontology for the discipline of information systems by applying the Grounded Theory method. Specifically we are using Roman Ingarden’s theory of scientific works to seed a coding family and adapting the method to ask relevant questions when analysing rich textual data. We have found that a guiding ontological theory, such as Ingarden’s, can be used to seed a coding family giving rise to a viable method for generating ontologies for research. This is significant because Grounded Theory may be one of the key methods for generating ontologies where substantial uniform quality text is available to the ontologist. We also present our partial analysis of information systems research.

Intent and Method: A Study of Female Characters in Aeschylean and Euripidean Drama

Aeschylus and Euripides used tragic female characters to help fulfill the purpose of religious celebration and to achieve the motivation of public reaction. The playwrights, revising myths about tragic woman and redefining the Greek definition of appropriate femininity, supported or questioned the very customs which they changed. Originally composed as part of a religious festival for Dionysus, the god of wine, revelry and fertility, the tragedies of Aeschylus and Euripides were evaluated by Aristotle. He favored Aeschylus over Euripides, but it appears as if his stipulations for tragic characterization do not apply to Aeschylean and Euripidean women. Modem critics question both Aristotle's analysis in the Poetics as well as the tragedies which he evaluated. As part of the assessment of Aeschylus, the character of the Persian Queen, Atossa, appears as a conradiction the images that Greeks maintain of non-Greeks. The Persians is discussed in relation to modem criticisms and as on its function as a warning against radical changes in Athenian domestic life. The Oresteia, a trilogy, also charts the importance of an atypical woman in Aeschylean tragedy, and how this role, Clytaemnestra, represents an extreme example of the natural and necessary evolution of families, households and kingdoms. In contrast to Aeschylus' plea to retain nomoi (traditional custom and law), EUripides' tragedy, the Medea, demonstrates the importance of a family and a country to provide security, especially for women. Medea's abandonment by Jason and subsequent desperation drives her to commit murder in the hope of revenge. Ultimately, Euripides advocates changes in social convention away from the alienation of non-Greek, non-citizens, and females. Euripides is, unfortunately, tagged a misogynist by some in this tragedy and another example-the Hippolytus. Euripides' Phaedra becomes entangled in a scheme of divine vengeance and ultimately commits suicide in an attempt to avoid societal shame. Far from treatises of hate, Euripidean women take advantage of the little power they possess within a constrictive social system. While both Aeschylus and Euripides revise customary images and expectations of women in the context of religiously-motivated drama, one playwright intends to maintain civic order and the other intends to challenge the secular norm.

Towards the confirmation of the MOA model : an applied approach

The aim of this paper is to develop a grounded understanding of the role that the MOA constructs play in influencing environmentally responsible  behaviour. Data collected is used to qualitatively confirm the MOA Model (Rothschild, 1999) in an environmental management application and provide a basis to inform the development of a comprehensive quantitative causal investigation. This study will seek to determine the specific contributions of each MOA factor in the study context. The case study chosen for this investigation is representative of other social marketing applications for the MOA framework. The case study concerns the behaviour of agrarian land managers with respect to the rabbit pest problem affecting rural Australia. The paper concludes by confirming the appropriateness of the constructs within the MOA Model.

Poetry as a starting point for drama: learning to tolerate ambiguity

This article explores the use of process drama in an English classroom to explore issues raised by 'A poem for the Rainforest' by Judith Nicholls. The drama is used to explore both the themes and forms of the poem, the episodic nature of the drama reflecting the episodic form of the poem. The work engages the students, and the process drama works to layer complexity onto the issues rather than simplifying them.
