We present ARGUS, a coordination system for unmanned aerial vehicles (UAVs) deployed to support situational awareness for disaster management settings. ARGUS is based on the max-sum algorithm, a well known decentralised coordination algorithm for multi-agent systems. In this demonstration, we present an interactive simulation environment, where a user acting as a first responder submits imagery...

UNLABELLED BACKGROUND The World Health Organization (WHO) collects and publishes surveillance data and statistics for select diseases, but traditional methods of gathering such data are time and labor intensive. Event-based biosurveillance, which utilizes a variety of Internet sources, complements traditional surveillance. In this study we assess the reliability of Internet biosurveillance a...

We describe and evaluate WatchTower, a system that simplifies the collection of Windows performance counter data, and Argus, a statistical methodology for evaluating this data and reducing the sheer volume of it. This is especially important when monitoring the performance of clusters for high performance computing. WatchTower’s overheads are comparable to those of Microsoft’s perfmon tool, whi...

Biological invasions with known histories are rare, especially in the sea, and empirical studies of the genetic consequences are even rarer. Fifty-five years ago, the state of Hawai'i began a remarkable, if unintentional, 'experiment' with the introduction of three reef fishes, Lutjanus fulvus, Cephalopholis argus and Lutjanus kasmira. All have since expanded from the initial introduction of 22...

The Caribbean spiny lobster Panulirus argus is a valuable fishing resource and the trade in frozen lobster tails is an important industry. However, the presence of the pathogenic virus Panulirus argus Virus 1 (PaV1), which causes systemic infection in P. argus and is particularly lethal to juvenile individuals, has not been previously examined in imported/exported lobster products. We used PCR ...

Accurate age estimates for Panulirus argus, the commercially important Caribbean spiny lobster, would greatly enhance life history and population analyses. Most age approximations of P. argus are based on size and growth data, but size is generally considered a poor proxy for age of crustaceans in the field because of numerous environmental, density-dependent, and fishery-related factors. An es...

This paper describes the ARGUS prototype, a high-density, low-power supercomputer built from an IXIA network analyzer chassis and load modules. The prototype is configured as a diskless distributed system that is scalable to 128 processors in a single 9U chassis. The entire system has a footprint of 0.25 m2 (2.5 ft2), a volume of 0.09 m3 (3.3 ft3) and maximum power consumption of less than 2200...

A fast second level trigger has been developed for the ARGUS experiment which recognizes tracks originating from the interaction region. The processor compares the hits in the ARGUS Micro Vertex Drift Chamber to 245760 masks stored in random access memories. The masks which are fully deened in three dimensions are able to reject tracks originating in the wall of the narrow beampipe of 10.5 mm r...

In the last 3 years the Department of Human Services in Victoria has recorded 3 outbreaks of gastroenteritis believed to be associated with consumption of ‘butterfish’. In Victoria, escolar (Lepidocybium flavobrunneum and Ruvettus pretiosus) and rudderfish (Centrolophus sp.) are commonly marketed under the name ‘butterfish’. True butterfish, (Scatophagus species) is caught as a by-catch in sein...
