DeSyRe: on-Demand System Reliability
No full textThe DeSyRe project builds on-demand adaptive and reliable Systems-on-Chips (SoCs). As fabrication technology scales down, chips are becoming less reliable, thereby incurring increased power and performance costs for fault tolerance. To make matters worse, power density is becoming a significant limiting factor in SoC design, in general. In the face of such changes in the technological landscape, current solutions for fault tolerance are expected to introduce excessive overheads in future systems. Moreover, attempting to design and manufacture a totally defect and fault-free system, would impact heavily, even prohibitively, the design, manufacturing, and testing costs, as well as the system performance and power consumption. In this context, DeSyRe delivers a new generation of systems that are reliable by design at well-balanced power, performance, and design costs. In our attempt to reduce the overheads of fault-tolerance, only a small fraction of the chip is built to be fault-free. This fault-free part is then employed to manage the remaining fault-prone resources of the SoC. The DeSyRe framework is applied to two medical systems with high safety requirements (measured using the IEC 61508 functional safety standard) and tight power and performance constraints
Introduction: Christos Tsiolkas and Contemporary Australia — The Outsider Artist
No full textChristos Tsiolkas is regularly acknowledged as one of the most important writers working in Australia—indeed, the world—today. However, his proclivity for the public essay (in venues such as The Monthly), as well as his willingness to speak out on important social and political issues (such as refugees and marriage equality), casts him not only as an important writer, but also as a critical public figure in contemporary Australia. This collection of articles takes the range of Tsiolkas’s works (both fiction and non-fiction, as well as their television and cinematic adaptations) as their impetus, using these as a model to explore the significance of Tsiolkas’s intellectual contribution to Australian public life. As such, these articles work across genre, across theories, across national and international borders, and across disciplines in order to make clear Tsiolkas’s contemporary significance. Building on recent book-length studies on the author, including Andrew McCann’s Christos Tsiolkas and the Fiction of Critique: Politics, Obscenity, Celebrity (2015) and my own Christos Tsiolkas: The Utopian Vision (2017), what these articles hold in common is an assertion that Tsiolkas’s fiction and non-fiction always and everywhere serve a political and social purpose. As I have argued elsewhere, Tsiolkas’s writing ultimately suggests the ways in which we can shape a better future for Australia

Suitable cache organizations for a novel biomedical implant processor
No full textThis paper evaluates various instruction- and data-cache organizations in terms of performance, power, energy and area on a suitably selected biomedical benchmark suite. The benchmark suite consists of compression, encryption and data-integrity algorithms as well as real implant applications, all executed on biomedical input datasets. Results are used to drive the (micro)architectural design of a novel microprocessor targeting microelectronic implants. Our profiling study has revealed a L1 instruction-cache of 8 KB size (when relaxed area constraints are imposed) and a L1 data-cache of 4 KB size, both structured as 2-way associative caches, as optimal organizations for the envisioned implant processor
Christos Tsiolkas: the utopian vision
No full textMore than two decades ago, Christos Tsiolkas’s his first novel Loaded was published and he had achieved a cult following in the short-lived grunge fiction scene of Australian writing. The novel was quickly adapted as the film Head On (1998), directed by Ana Kokkinos, and starring popular young Greek actor, Alex Dimitriades; like the novel, it was well-received by critics, if not by mainstream literary and cinematic culture. For the next few years, Tsiolkas worked on Jump Cuts, an experimental collaborative autobiography, with Sasha Soldatow (1996), as well as a number of theatre productions – Who’s Afraid of the Working Class? (1999, co-written with Andrew Bovell, Melissa Reeves and Patricia Cornelius, and adapted to film as Blessed, also directed by Kokkinos [2009]), Thug (1998, written with Spiro Economopolous), and Elektra AD (1999) – but when The Jesus Man (1999) was published, its violent depiction of depression and suicide received critical attention as offensive and unnecessary. Partly because of the reception of The Jesus Man, and partly because of the density of its subject matter, his next novel, Dead Europe (2005) took six years to write. In the interim, he published a critical study of the film The Devil’s Playground (2002), and several more plays and screenplays: Viewing Blue Poles (2000), Saturn’s Return (2000), Fever (2002, co-written with Bovell, Reeves and Cornelius), Dead Caucasians (2002), Non Parlo di Salo (2005, written with Economopoulous), and The Hit (2006, written with Netta Yashin). Dead Europe was a triumphant return: it won the Age Book of the Year and the Melbourne Best Writing Award in 2006.
But it was the extraordinary critical and commercial success of The Slap (2008) which entirely changed Tsiolkas’s personal and professional circumstances. It was the fourth-highest selling book by an Australian author in 2009, won the ALS Gold Medal, was longlisted for the Man Booker Prize, shortlisted for the Miles Franklin Literary Award, won the Commonwealth Writers’ Prize and was Book of the Year for both the Australian Booksellers Association and the Australian Book Industry Award. The Slap was also adapted as a popular television series for the ABC in 2011, and for NBC in the United States in 2015. For the first time in his career, Tsiolkas was able to dedicate himself to writing full-time, but the attention paid to the novel also meant that Tsiolkas was now a household name – no longer a cult writer, his opinions are now courted and offered in popular and political publications. Barracuda (2013) follows the social realism of The Slap, and sold similarly well, riding on the back of its extraordinary predecessor. Merciless Gods (2014), a collection of short stories, some new, some previously published, is only recently being taken up by popular critics.
Tsiolkas’s work has become increasingly popular and appealing to readers outside of the academy. Tsiolkas’s works adopt a Modernist attitude to the concept of a utopia – a negative politics which simultaneously draws attention to the insufficiency of the present, a pastoral nostalgia for the past, and a longing for the impossible future to come. This first in-depth study of his entire corpus provides an understanding of Tsiolkas’s position in relation to Modernism, thereby drawing out his points about character, setting and politics, thereby helping us to think about what place his ideas about the individual and the community might have in our reading of contemporary Australia and contemporary world literature
Author self-citation in orthodontics is associated with author origin and gender.
Get PDFBACKGROUND
The aims of this bibliometric study were to determine author self-citation trends in high-impact orthodontic literature and to investigate possible association between self-citation and publication characteristics.
METHODS
Six orthodontic journals with the highest impact factor as ranked by 2017 Journal Citation Reports were screened for a full publication year (2018) for original research articles, reviews, and case reports. Eligible articles were scrutinized for article and author characteristics and citation metrics. Univariable and multivariable negative binomial regression was used to examine associations between self-citation incidence and publication characteristics.
RESULTS
Medians for author self-citation rate of the most self-citing authors and self-citations were 3.03% (range 0-50) and 1 (range 0-19), respectively. In the univariable analysis, there was no association between self-citation counts and study type (P = 0.41), article topic (P = 0.61), number of authors (P = 0.62), and rank of authors (P = 0.56). Author origin (P = 0.001), gender (P = 0.001) and journal (P = 0.05) were associated with self-citation counts and in the multivariable analysis only origin and gender remained strong self-citation predictors. Asian authors and females self-cited significantly less often than all other regions and male authors.
CONCLUSIONS
Authors in orthodontics do not self-cite at a frequency that suggests potential citation manipulation. Author origin and gender were the only variables associated with citations counts. More bibliometric research is necessary to draw solid conclusions about author self-citation trends in orthodontic literature
The Case for a Generic Implant Processor
Get PDFA more structured and streamlined design of implants is nowadays possible. In this paper we focus on implant processors located in the heart of implantable systems. We present a real and representative biomedical-application scenario where such a new processor can be employed. Based on a suitably selected processor simulator, various operational aspects of the application are being monitored. Findings on performance, cache behavior, branch prediction, power consumption, energy expenditure and instruction mixes are presented and analyzed. The suitability of such an implant processor and directions for future work are given.Microelectronics and Computer EngineeringMechanical, Maritime and Materials Engineerin
Contemporary Australian masculinities and De Certeau’s concept of la perruqe in Christos Tsiolkas’ novel The Slap (2008)
No full textThis paper will focus on how Christos Tsiolkas the author of The Slap (2008) invites us to view the complex range of private lives of his male characters living in suburban Melbourne through their daily routines, conversations and innermost thoughts. On the surface most appear to be participating in and achieving a certain level of success in their lives. However, this novel reveals when we agitate and dig below the “practices of everyday life” there is often a disquiet simmering away under the facade of family harmony, male bravado and contentment. This paper will argue that as a result of dissatisfaction with the established order of their lives, each man has managed to create another level of meaning for himself, his own form of la perruque (De Certeau 2011: 29),the concept of living proposed by Michel De Certeau. A treatment of the characters in this article draws on, and is used to illustrate the paradigm
Carcerals and Olympic Masculinities in Christos Tsiolkas’s Barracuda
Get PDFIn an effort to draw attention to the masculine crisis occurring in the era of globalisation, this paper elaborates on Australian author Christos Tsiolkas’s novel Barracuda and the central character’s self-discipline and struggle into reaching Olympic achievement. The course of his rise as a potential Olympic athlete but also his fall and crisis within an institutional framework of disciplines, which often symbolically turn into nightmarish prisons, resonate with Michel Foucault’s 1975 work Discipline and Punish. The latter’s ideas about discipline and the “carceral” will help interpret Tsiolkas’s novel and further understand how the Olympics work as a mechanism of discipline and compliance towards a kind of hegemonic masculinity and its inevitable crisis
