The symbiosis of improvised and rehearsed elements in the creation of contemporary jazz ensemble music

This research investigates the symbiotic relationship between composition and improvisation and the notion of improvisation itself. With a specific interest in developing, extending and experimenting with the relationship of improvisation within predetermined structures, the creative work component of this research involved composing six new works with varying approaches for The Andrea Keller Quartet and guest improvisers, for performance on a National Australian tour. This is documented in the CD recording Galumphing Round the Nation - Collaborations Tour 2009. The exegesis component is intended to run alongside the creative work and discusses the central issues surrounding improvisation in an ensemble context and the subject of composing for improvisers. Specifically, it questions the notion that when music emphasises a higher ratio of spontaneous to pre-determined elements, and is exposed to the many variables of a performance context, particularly through its incorporation of visitant improvisers, the resultant music should potentially be measurably altered with each performance. This practice-led research demonstrates the effect of concepts such as individuality, variability within context, and the interactive qualities of contemporary jazz ensemble music. Through the analysis and comparison of the treatment of the six pieces over thirteen performances with varying personnel, this exegesis proposes that, despite the expected potential for spontaneity in contemporary jazz music, the presence of established patterns, the desire for familiarity and the intuitive tendency towards accepted protocols ensure that the music which emerges is not as mutable as initially anticipated.

Is there a physicality requirement at Common Law? : a survey of the Pre-NRDC cases discussing ‘Manufacture’

One of the fundamental issues that remains unresolved in patent law today, both in Australia and in other jurisdictions, is whether an invention must produce a physical effect or cause a physical transformation of matter to be patentable, or whether it is sufficient that an invention involves a specific practical application of an idea or principle to achieve a useful result. In short, the question is whether Australian patent law contains a physicality requirement. Despite being recently considered by the Federal Court, this is arguably an issue that has yet to be satisfactorily resolved in Australia. In its 2006 decision in Grant v Commissioner of Patents, the Full Court of the Federal Court of Australia found that the patentable subject matter standard is rooted in the physical, when it held that an invention must involve a physical effect or transformation to be patent eligible. That decision, however, has been the subject of scrutiny in the academic literature. This article seeks to add to the existing literature written in response to the Grant decision by examining in detail the key common law cases decided prior to the High Court’s watershed decision in National Research Development Corporation v Commissioner of Patents, which is the undisputed authoritative statement of principle in regards to the patentable subject matter standard in Australia. This article, in conjunction with others written by the author, questions the Federal Court’s assertion in Grant that the physicality requirement it established is consistent with existing law.

Face recognition using fractal codes

In this paper we propose a new method for face recognition using fractal codes. Fractal codes represent local contractive, affine transformations which when iteratively applied to range-domain pairs in an arbitrary initial image result in a fixed point close to a given image. The transformation parameters such as brightness offset, contrast factor, orientation and the address of the corresponding domain for each range are used directly as features in our method. Features of an unknown face image are compared with those pre-computed for images in a database. There is no need to iterate, use fractal neighbor distances or fractal dimensions for comparison in the proposed method. This method is robust to scale change, frame size change and rotations as well as to some noise, facial expressions and blur distortion in the image

Machine recognition of hand-drawn circuit diagrams

An application of image processing techniques to recognition of hand-drawn circuit diagrams is presented. The scanned image of a diagram is pre-processed to remove noise and converted to bilevel. Morphological operations are applied to obtain a clean, connected representation using thinned lines. The diagram comprises of nodes, connections and components. Nodes and components are segmented using appropriate thresholds on a spatially varying object pixel density. Connection paths are traced using a pixel-stack. Nodes are classified using syntactic analysis. Components are classified using a combination of invariant moments, scalar pixel-distribution features, and vector relationships between straight lines in polygonal representations. A node recognition accuracy of 82% and a component recognition accuracy of 86% was achieved on a database comprising 107 nodes and 449 components. This recogniser can be used for layout “beautification” or to generate input code for circuit analysis and simulation packages

Spaces of possibility in pre-service teacher education

Pre-service teacher education is a spatialized enterprise. It operates across a number of spaces that may or may not be linked ideologically and/or physically. These spaces can include daily practices, locations, infrastructure, relationships and representations of power and ideology. The interrelationships between and within these (sometimes competing) spaces for pre-service teachers will influence their identities as teachers and learners across time and space. Pre-service teachers are expected to make the connections between these often-contradictory spaces with little or no guidance on how to negotiate such complex relationships. These are difficult spaces, yet the slippages and gaps between these spaces offer generative possibilities. This paper explores these spaces of possibility for pre-service teacher education, and uses the spatial theories of Lefebvre (1991) and Foucault (1977, 1980) to argue that critical reflective practice can be used to create a ‘thirdspace’ (Soja, 1996) for reconstructing future practice.

Resisting contradictions : non-Indigenous pre-service teacher responses to critical Indigenous studies

The study examines non-Indigenous pre-service teacher responses to the authorisation of Indigenous knowledge perspectives in compulsory Indigenous studies with a primary focus on exploring the nature and effects of resistance. It draws on the philosophies of the Japanangka teaching and research paradigm (West, 2000), relationship theory (Graham, 1999), Indigenist methodologies and decolonisation approaches to examine this resistance. A Critical Indigenist Study was employed to investigate how non-Indigenous pre-service teachers managed their learning, and how they articulated shifts in resistance as they progressed through their studies. This study explains resistance to compulsory Indigenous and how it can be targeted by Indigenist Standpoint Pedagogy. The beginning transformations in pre-service teacher positioning in relation to Australian history, contemporary educational practice, and professional identity was also explored.

Advanced Computational Intelligence System for inverse aeronautical design optimisation

Abstract—Computational Intelligence Systems (CIS) is one of advanced softwares. CIS has been important position for solving single-objective / reverse / inverse and multi-objective design problems in engineering. The paper hybridise a CIS for optimisation with the concept of Nash-Equilibrium as an optimisation pre-conditioner to accelerate the optimisation process. The hybridised CIS (Hybrid Intelligence System) coupled to the Finite Element Analysis (FEA) tool and one type of Computer Aided Design(CAD) system; GiD is applied to solve an inverse engineering design problem; reconstruction of High Lift Systems (HLS). Numerical results obtained by the hybridised CIS are compared to the results obtained by the original CIS. The benefits of using the concept of Nash-Equilibrium are clearly demonstrated in terms of solution accuracy and optimisation efficiency.

What determines real-world meal size? Evidence for pre-meal planning

The customary approach to the study of meal size suggests that ‘events’ occurring during a meal lead to its termination. Recent research, however, suggests that a number of decisions are made before eating commences that may affect meal size. The present study sought to address three key research questions around meal size: the extent to which plate cleaning occurs; prevalence of pre-meal planning and its influence on meal size; and the effect of within-meal experiences, notably the development of satiation. To address these, a large-cohort internet-based questionnaire was developed. Results showed that plate cleaning occurred at 91% of meals, and was planned from the outset in 92% of these cases. A significant relationship between plate cleaning and meal planning was observed. Pre meal plans were resistant to modification over the course of the meal: only 18% of participants reported consumption that deviated from expected. By contrast, 28% reported continuing eating beyond satiation, and 57% stated that they could have eaten more at the end of the meal. Logistic regression confirmed pre-meal planning as the most important predictor of consumption. Together, our findings demonstrate the importance of meal planning as a key determinant of meal size and energy intake.

Influencing pre-service teachers, skills and attitudes towards diversity. Is DOL the Answer?

Abstract: This paper reports on a preliminary investigation into the success of an undergraduate course, in helping preservice teachers at a regional university develop the skills and attitudes necessary to design inclusive learning environments that cater for, and celebrate, difference. The study is particularly relevant given recommendations by the Education Queensland Ministerial Taskforce (Queensland Government, 2004) that all pre-service teacher education programs must ensure that inclusive education is a pervasive theme. The paper starts by providing an overview of inclusive contexts and a rationale for inclusive education including critical elements. This leads into an overview of the undergraduate course EDED11400 Managing Diversity and discussion, based on feedback from the teaching team, on the capacity for the course to help pre-service teachers develop inclusive curriculum and pedagogical practices. The pedagogical framework Dimensions of Learning* is then discussed, with consideration given to whether this framework with its focus on critical thinking and habits of mind, might improve future learning outcomes in the course EDED11400 Managing Diversity. (*Dimensions of Learning is a pedagogical framework designed to teach thinking skills (Marzano et al., 1988). It explores five types of thinking represented in the framework by five dimensions of learning.)

Unravelling design : fashion, dressmaking, ethos

Discourses on ethical fashion are usually geared toward finding solutions—or right outcomes—to ethical problems, based on a teleological model of design and a positioning of the designer as an autonomous and isolated design authority. This practice-led project argues, however, that considerations of design ethics must take into account not only the outcome of a design, but also the ongoing, lived experience of designing as a making located in pre-existing social, historical and cultural conditions. Through an exploration of my own dressmaking practice and a reading of ethos as location, I argue for two things: one, for the designer as a located entity rather than an autonomous "author", and, two, against design-asplan and the original design object, and for the circular and conditioned character of design. Through a connection to ethos, understandings of design ethics shift from an end object focus to something situated, and invested in, everyday lived experience—and always in the making.

Atomistic exploration of deformation properties of copper nanowires with pre-existing defects

Based on the embedded atom method (EAM) and molecular dynamics (MD) method, in this paper, the tensile deformation properties of Cu nanowires (NWs) with different pre-existing defects, including single surface defects, surface bi-defects and single internal defects, are systematically studied. In-depth deformation mechanisms of NWs with pre-existing defects are also explored. It is found that Young's modulus is insensitive to different pre-existing defects, but yield strength shows an obvious decrease. Defects are observed influencing greatly on NWs' tensile deformation mechanisms, and playing a role of dislocation sources. Besides of the traditional deformation process dominated by the nucleation and propagation of partial dislocations, the generations of twins, grain boundaries, fivefold deformation twins, hexagonal close-packed (HCP) structure and phase transformation from face-centred cubic (FCC) structure to HCP structure have been triggered by pre-existing defects. It is found that surface defect intends to induce larger influence to yield strength than internal defect. Most importantly, the defect that lies on slip planes exerts larger influence than other defects. As expected, it is also found that the more or longer of the defect, the bigger influence will be induced.
