      Observing interactions among chemical species and microorganisms in the earth's sub-surface is a common task in the field of geology. Bioremediation experiments constitute one such class of interactions which focus on ...
    • Detangler: Visual Analytics for Multiplex Networks 

      Renoust, Benjamin; Melancon, Guy; Munzner, Tamara (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      A multiplex network has links of different types, allowing it to express many overlapping types of relationships. A core task in network analysis is to evaluate and understand group cohesion; that is, to explain why groups ...
    • Visualnostics: Visual Guidance Pictograms for Analyzing Projections of High-dimensional Data 

      Lehmann, Dirk J.; Kemmler, Fritz; Zhyhalava, Tatsiana; Kirschke, Marco; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      The visual analysis of multivariate projections is a challenging task, because complex visual structures occur. This causes fatigue or misinterpretations, which distorts the analysis. In fact, the same projection can lead ...
    • Visual Analysis of Spatio-Temporal Data: Applications in Weather Forecasting

      Weather conditions affect multiple aspects of human life such as economy, safety, security, and social activities. For this reason, weather forecast plays a major role in society. Currently weather forecasts are based on ...
    • A Shot at Visual Vulnerability Analysis 

      Kerzner, Ethan; Butler, Lee A.; Hansen, Charles; Meyer, Miriah (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Increasing the safety of vehicles is an important goal for vehicle manufacturers. These manufacturers often turn to simulations to understand how to improve a vehicle's design as real-world safety tests are expensive and ...
    • Visualizing Time-Specific Hurricane Predictions, with Uncertainty, from Storm Path Ensembles
