Ambient Australia: Music, Meditation And Tourist Places, Christopher Gibson, John Connell
Ambient Australia: Music, Meditation And Tourist Places, Christopher Gibson, John Connell
Chris Gibson
This chapter examines how music informs the creation of tourist places in Australia. It discusses one genre-ambient music-and the way it is related to geography both symbolically (in terms of cultural representations), and literally (in terms of links to musical and touristic activities in particular towns). The rise of ambient music has contributed to the imaginative representation of a touristic Australia of "natural" physical and cultural landscapes, where indigenous people are particularly significant. Designed to encourage relaxation and even sleep, in its cover art, its sounds and lyrics (where they exist), ambient music has emphasized "special" places both generic and …
Cultural Economy: Achievements, Divergences, Future Prospects, Chris Gibson
Cultural Economy: Achievements, Divergences, Future Prospects, Chris Gibson
Chris Gibson
This paper reflects on two decades’ scholarship in geography on cultural economy, assessing strides made against some of the expectations of early proponents. Cultural economy continues to be a polysemic term. In some quarters, it refers to a type of economic geography into which matters of ‘culture’ are absorbed. This work frequently focuses on the empirics of the so-called ‘cultural and creative industries’. Others see cultural economic research as an opportunity to move beyond the epistemological constraints of ‘culture’ and ‘economy’, questioning their status as foundational categories. This latter approach has been used in a broader set of empirical projects …

Uprising: The Internet's Unintended Consequences, Marcus Breen
Marcus Breen
The Internet has transformed the social relations that were once managed by the powers that be. As a rapidly maturing communications technology, the Internet has brought people together even while it has reinforced privatism. The desktop computer, the laptop, the cellular and mobile phone, the Global Positoning System, the pilotless drone aircraft, video games and government documents courtesy of Wikileaks, all are connected on the network of networks. Together these converged elements of a global socio-technical system offer wonderful possibilities for human emancipation, even while those ideas collide with established ideas of civility and decency. Utilizing a transdisciplinary approach, Uprising …
Improved Duplicate Bug Report Identification, Yuan Tian, Chengnian Sun, David Lo
Improved Duplicate Bug Report Identification, Yuan Tian, Chengnian Sun, David Lo
David LO
Bugs are prevalent in software systems. To improve the reliability of software systems, developers often allow end users to provide feedback on bugs that they encounter. Users could perform this by sending a bug report in a bug report management system like Bugzilla. This process however is uncoordinated and distributed, which means that many users could submit bug reports reporting the same problem. These are referred to as duplicate bug reports. The existence of many duplicate bug reports may cause much unnecessary manual efforts as often a triager would need to manually tag bug reports as being duplicates. Recently, there …

Identifying Linux Bug Fixing Patches, Tian Yuan, Julia Lawall, David Lo
David LO
In the evolution of an operating system there is a continuing tension between the need to develop and test new features, and the need to provide a stable and secure execution environment to users. A compromise, adopted by the developers of the Linux kernel, is to release new versions, including bug fixes and new features, frequently, while maintaining some older “longterm” versions. This strategy raises the problem of how to identify bug fixing patches that are submitted to the current version but should be applied to the longterm versions as well. The current approach is to rely on the individual …

Understanding Task-Driven Information Flow In Collaborative Networks, Gengxin Miao, Shu Tao, Winnie Cheng, Randy Moulic, Louise E. Moser, David Lo, Xifeng Yan
David LO
Collaborative networks are a special type of social network formed by members who collectively achieve specific goals, such as fixing software bugs and resolving customers’ problems. In such networks, information flow among members is driven by the tasks assigned to the network, and by the expertise of its members to complete those tasks. In this work, we analyze real-life collaborative networks to understand their common characteristics and how information is routed in these networks. Our study shows that collaborative networks exhibit significantly different properties compared with other complex networks. Collaborative networks have truncated power-law node degree distributions and other organizational …
Are Faults Localizable?, - Lucia, Thung Ferdian, David Lo, Lingxiao Jiang
Are Faults Localizable?, - Lucia, Thung Ferdian, David Lo, Lingxiao Jiang
David LO
Many fault localization techniques have been proposed to facilitate debugging activities. Most of them attempt to pinpoint the location of faults (i.e., localize faults) based on a set of failing and correct executions and expect debuggers to investigate a certain number of located program elements to find faults. These techniques thus assume that faults are localizable, i.e., only one or a few lines of code that are close to one another are responsible for each fault. However, in reality, are faults localizable? In this work, we investigate hundreds of real faults in several software systems, and find that many faults …
Inferring Class Level Specifications For Distributed Systems, Sandeep Kumar, Siau-Cheng Khoo, Abhik Roychoudhury, David Lo
Inferring Class Level Specifications For Distributed Systems, Sandeep Kumar, Siau-Cheng Khoo, Abhik Roychoudhury, David Lo
David LO
Distributed systems often contain many behaviorally similar processes, which are conveniently grouped into classes. In system modeling, it is common to specify such systems by describing the class level behavior, instead of object level behavior. While there have been techniques that mine specifications of such distributed systems from their execution traces, these methods only mine object-level specifications involving concrete process objects. This leads to specifications which are large, hard to comprehend, and sensitive to simple changes in the system (such as the number of objects). In this paper, we develop a class level specification mining framework for distributed systems. A …

In Process Surface Roughness Estimation In Grinding, Li Xue, Fazel Naghdy, Christopher Cook
In Process Surface Roughness Estimation In Grinding, Li Xue, Fazel Naghdy, Christopher Cook
Christopher Cook
An intelligent sensor system for on-line estimation of surface roughness in the grinding process is developed. The system consists of a statistical signal processing algorithm and a neuro-fuzzy model of surface roughness. The model is established using a set of experimental data. The sensor signals of acoustic emission CAE), normal force and tangential force generated in grinding zone are acquired online in real time. The surface roughness of the ground workpiece is measured offline and used as the target output of the model. A first order Sugeno-type neuro-fuzzy inference system is employed to optimize the model by minimizing a sum …

Precis: A Design-Time Precision Analysis Tool, Mark L. Chang, Scott Hauck
Mark L. Chang
Currently, few tools exist to aid the FPGA developer in translating an algorithm designed for a general-purpose-processor into one that is precision-optimized for FPGAs. This task requires extensive knowledge of both the algorithm and the target hardware. We present a design-time tool, Precis, which assists the developer in analyzing the precision requirements of algorithms specified in MATLAB. Through the combined use of simulation, user input, and program analysis, we demonstrate a methodology for precision analysis that can aid the developer in focusing their manual precision optimization efforts.

In this paper, we present a method for FPGA datapath precision optimization subject to user-defined area and error constraints. This work builds upon our previous research which presented a methodology for optimizing the dynamic range- the most significant bit position. In this work, we present an automated optimization technique for the least-significant bit position of circuit datapaths. We present results describing the effectiveness of our methods on typical signal and image processing kernels.
Interactionless Calendar-Based Training For 802.11 Localization, Mark Chang, Andrew J. Barry, Noah L. Tye
Interactionless Calendar-Based Training For 802.11 Localization, Mark Chang, Andrew J. Barry, Noah L. Tye
Mark L. Chang
This paper presents our work in solving one of the weakest links in 802.11-based indoor-localization: the training of ground-truth received signal strength data. While crowdsourcing this information has been demonstrated to be a viable alternative to the time consuming and accuracy-limited process of manual training, one of the chief drawbacks is the rate at which a system can be trained. We demonstrate an approach that utilizes users' calendar and appointment information to perform interactionless training of an 802.11-based indoor localization system. Our system automatically determines if a user attended a calendar event, resulting in accuracy comparable to our previously published …
