“The Tasmanian ICT of CSIRO developed a Sensor Web test-bed system for the Australian water domain. This system provides an open platform to access and integrate near real time water information from distributed sensor networks. Traditional hydrological models can be adopted to analyze the data on the Sensor Web system. However, the requirements on high data quality and high level domain knowledge may greatly limit the application of these models. To overcome some these limitations, this paper proposes a data mining approach to analyze patterns and relationships among different hydrological events. This approach provides a flexible way to make use of data on the Hydrological Sensor Web.”

“Future sea level rise caused by climate change would disrupt the physical processes, economic activities, and social systems in coastal regions. Based on a hypothetical global sea level increase of one to six meters, we developed GIS methods to assess and visualize the global impacts of potential inundation using the best available global datasets. After susceptible areas were delineated, we estimated that the size of the areas is between 1.055 (one meter) to 2.193 million km2 (six meters). Population in the susceptible areas was estimated to range from 108 (one meter) to 431 million (six meters) people. Among the seven land-cover types in the susceptible areas, forest and grassland account for more than 60 percent for all the increments of sea level rise. A suite of interactive visualization products was also developed to understand and communicate the ramifications of potential sea level rise.”

“Social contact crimes and robberies within South Africa are still a dominant criminal behaviour that labels South Africa as one of the most violent crime countries in the world. Contact crimes are social or domestic in nature and occur primarily within the social environment of the perpetrator, such as his/her private residence.”
