If we were to have a Grid infrastructure for visualization, what technologies would be needed to build such an infrastructure, what kind of applications would benefit from it, and what challenges are we facing in order to accomplish this goal? In this report, we make use of the term 'visual supercomputing' to encapsulate a subject domain concerning the(More)
PURPOSE Commercial interventional radiology vascular simulators emulate instrument navigation and device deployment, though none supports the Seldinger technique, which provides initial access to the vascular tree. This paper presents a novel virtual environment for teaching this core skill. METHODS Our simulator combines two haptic devices: vessel(More)
The Internet has continued to evolve, becoming increasingly media rich. It is now a major platform for video content, which is available to a variety of users across a range of devices. Subtitles enhance this experience for many users. However, subtitling techniques are still based on early television systems, which impose limitations on font type, size and(More)
OBJECTIVE To demonstrate that posttranslational modification of type II collagen (CII) by reactive oxygen species (ROS), which are known to be present in inflamed arthritic joints, can give rise to epitopes specific to damaged cartilage in rheumatoid arthritis (RA) and osteoarthritis (OA) and to establish a proof of concept that antibodies specific to(More)
We present epSpread, an analysis and storyboarding tool for geo-located microblogging data. Individual time points and ranges are analysed through queries, heatmaps, word clouds and stream-graphs. The underlying narrative is shown on a storyboard-style timeline for discussion, refinement and presentation. The tool was used to analyse data from the VAST(More)
INTRODUCTION We previously demonstrated that a single-chain fragment variable (scFv) specific to collagen type II (CII) posttranslationally modified by reactive oxygen species (ROS) can be used to target anti-inflammatory therapeutics specifically to inflamed arthritic joints. The objective of the present study was to demonstrate the superior efficacy of(More)
Recent hardware and software advances have demonstrated that it is now practicable to run large visual computing tasks over heterogeneous hardware with output on multiple types of display devices. As the complexity of the enabling infrastructure increases, then so too do the demands upon the programmer for task integration as well as the demands upon the(More)
Millions of people rely on subtitles when watching video content. The current change in media viewing behaviour involving computers has resulted in a large proportion of people turning to online sources as opposed to regular television for news information. This work analyses the user experience of viewing subtitled news videos presented as part of a web(More)
