CFD-based shape optimisation with grid-enabled design search toolkits
No full textThis paper presents an application of applying Grid computing technologies in the field of engineering design optimisation using computational fluid dynamics (CFD). Three essential elements in CFD-based shape optimisation problems (CAD, mesh generation, and solution) are integrated and automated within the Matlab scripting environment augmented with Grid-enabled computation and database toolkits in the form of Matlab functions. The toolkits allow easy access to remote computational resources and data archive capabilities. A design search and optimisation package is exposed to Matlab users in various ways and applied to an engine nacelle shape optimisation problem. A response surface model is constructed and searches conducted on it reveal the effect of negative scarf angle on the aerodynamic performance of the nacelle
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Before the Gold Rush: Culture Without Industry in China
No full textKeane illustrates the fundamental concepts of creativity and creativity industries with the rising trend of a state-dominated model as represented by China. This chapter discusses the “creativity” element in the cultural-creative industries by returning to the fundamental question of how creativity interacts with the market and economics. Keane also problematizes the term “industries,” which mistakenly focuses on neoliberalism. The author suggests in the highly regulated market under the pretext of cultural policy in China, is in fact a kind of authoritarian liberalism under which the role of the creative industries is highly questionable
Keane - introductory talk
No full textPsychosis on Screen is a season of three contemporary films depicting various experiences of psychosis. It aims to uncover the creativity often inherent in psychosis and to develop a shared, more human understanding of these sometimes frightening experiences.
'Shock of the Fall' author Nathan Filer will offer an introductory talk before the first screening. 'Keane' is a 2004 American drama film written and directed by Lodge Kerrigan
The Polish Premiere of John Millington Synge’s “The Playboy of the Western World”
No full textThe article traces the history of the Polish premiere and an early reception of
J.M. Synge’s The Playboy of the Western World. The author draws attention to similarities between Irish and Polish political and historical situations in which the plays premiered, respectively, in 1907 and in 1913. Firstly, Keane concentrates on analyzing the translator’s strategy in rendering the difficult Hyberno-English dialect present in Synge’s play. The translator, Florian Sobieniowski, chose to render the specific diction of the play using the poetic language of the Young Poland movement. He also modelled his translation on the language and partly the imagery of Stanislaw Wyspianski’s acclaimed play The Wedding (Wesele, 1901). Keane discusses some of the translator’s choices and provides the summary of the critical response to what he terms the acculturation policy of the translator. Analyzing fragments of most characteristic reviews of the Polish premiere of Synge’s play, Keane discusses the presence of cultural stereotyping and the reactions to acculturation in the Polish theatre and culture
On the universality of Keane & Adrian's valid detection probability in PIV
No full textFor the reliable estimation of velocity vector fields by means of particle image velocimetry (PIV), the cross-correlation functions calculated from the signal within each interrogation window must feature a distinct peak that represents the average shift of the particle image ensemble. A high valid detection probability (VDP) of the correct orrelation peak is necessary in order to compute valid but also accurate velocity fields. According to Keane and Adrian it is believed that the so-called effective number of particle images NIFIFO must be around 6 to obtain 95% valid detection probability (Keane and Adrian 1992 Appl. Sci. Res. 49 191-215). To prove the findings of Keane and Adrian, this work examines the sensitivity of the VDP on image parameters, flow parameters as well as on evaluation parameters in more detail. The most important result is that the effective number of particle images NIFIFO is not suited to predict the VDP in the case of moderate or strong out-of-plane motion. This can be explained by the fact that the VDP depends not only on the number of particle images correctly paired, but also on the number of particle images remaining without partner, which yield spurious correlation peaks. This point remained unnoticed in the work of Keane and Adrian. The findings of this investigation help to better understand the occurrence of false vectors and enable the PIV user to improve the measurement setup as well as the PIV evaluation in order to minimize spurious vectors.Aerodynamic
Two dimensional airfoil optimisation using CFD in a grid computing environment
No full textIn this paper, a two-dimensional airfoil shape optimisation problem is investigated using CFD within a grid computing environment (GCE) implemented in Matlab. The feature-based parametric CAD tool ProEngineer is used for geometry modelling. The industrial level mesh generation tool Gambit and flow solver Fluent are employed as remote services using the Globus Toolkit as the low level API. The objective of the optimisation problem is to minimize the drag-to-lift coefficient ratio for the given operating condition. A Matlab interface to the design exploration system (OPTIONS) is used to obtain solutions for the problem. The adoption of grid technologies not only simplifies the integration of proprietary software, but also makes it possible to harness distributed computational power in a consistent and flexible manner
Numerical optimisation as grid services for engineering design
No full textIn this paper we discuss the use of Grid services, an emerging Internet-based technology, to enable the application of numerical optimisation algorithms in heterogeneous, distributed systems for engineering design optimisation tasks. By being presented as Grid services, numerical optimisation algorithms can be consumed with a number of message interactions. The services are built using a combination of standard Web services and newly developed Grid technologies, based on the concept of Reverse Communication. The proposed approach eases the burden of integration by encapsulating optimisation algorithms into generic interfaces, which can be integrated into different client environments.
The design of the optimisation Grid services is explained in detail, and is illustrated with concrete implementations. We also demonstrate the use of the optimisation services with real engineering design optimisation problems performed in scripting problem solving environment
