Advances in surveillance science have supported public health agencies in tracking and responding to disease outbreaks. Increasingly, epidemiologists have been tasked with interpreting multiple streams of heterogeneous data arising from varied surveillance systems. As a result public health personnel have experienced an overload of plots and charts as(More)
The processing power and flexibility of recent rasterization hardware permits to speed up image generation through raytracing. This paper introduces a method that performs ray processing on the GPU in parallel to shading operations on the CPU. It effectively exploits CPU-GPU parallelism in a way that can be integrated into existing implementations utilizing(More)
The International Society for Disease Surveillance (ISDS) celebrates its 10th annual meeting with the arrival of the 2011 ISDS Annual Conference, ‘Building the Future of Public Health Surveillance’.

To study the influence o f host age, inoculum size, and route o f infection on Trypanosoma (Herpetosoma) rangeli, 12 lots o f 6.0 g albino mice (NMRI strain) were infected up. with from 25x101 to 25xl(fi trypomastigotes/gram body weight harvested from LIT medium. The lower inocula produced low but persistent parasitemias, while the higher inocula produced(More)
