Pathogen outbreaks (i.e., of bacteria and viruses) in hospitals can cause high mortality rates increase costs for significantly. An outbreak is generally noticed when the number infected patients rises above an endemic level or usual prevalence a pathogen defined population. Reconstructing transmission pathways back to source -- patient zero index requires analysis microbiological data contacts. This often manually completed by infection control experts. We present novel visual analytics...
Abstract Uncertainty about possible train delays has an impact on trips, as the exact arrival time is unknown during trip planning. Delays can lead to missing a connecting at transfer station, or coming too late appointment destination. Facing this uncertainty, traveler may wish use earlier different connection arriving well before appointment. Currently, planning based scheduled times of connections between two stations. Information approximate only available shortly departure. Although...
The spread of multidrug resistant organisms (MDRO) is a global healthcare challenge. Nosocomial outbreaks caused by MDRO are an important contributor to this threat. Computer-based applications facilitating outbreak detection can be essential address issue. To allow application reusability across institutions, the various heterogeneous microbiology data representations needs transformed into standardised, unambiguous models. In work, we present multi-centric standardisation approach using...
Static geolocated graphs have nodes connected by edges, where both can geographic location and associated attributes. For example, it be uncertain exactly a node is located or whether an edge between two exists. Because source data often incomplete inexact, necessary to visualize this uncertainty help users make appropriate decisions. The proposed typology of extends related typologies with specific features needed for characterizing in static graphs.
Bacteria and viruses are transmitted among patients in the hospital. Infection control experts develop strategies for infection control. Currently, this is done mostly manually, which time-consuming error-prone. Visual analysis approaches mainly focus disease spread on population level.We learn a RNN model detection of potential infections, transmissions factors. We present novel interactive visual interface to explore results. Together with experts, we apply our approach real hospital...
Abstract When planning series of events or processes, everyone has to cope with temporal uncertainty. Popular examples are holiday train trips. There several approaches visualize uncertainty when data and already defined, but common research usually does not take into account, neither as input nor output. To develop our design, we considered a variety for visualization used participatory evaluation validate concept. Our design aims at using this while sketching the plan interactively. The...
In this paper, we analyze the layout stability for squarify and slice-and-dice treemap algorithms when changingthe visualization containers resolution. We also explore how rescaling a finished to another resolution compares toa recalculated layout, i.e. fixed versus changing layout. For our evaluation, examine real world use-case anduse total of 240000 random data visualizations. Rescaling or layouts affects aspectratios. Recalculating is equivalent since layout not affected by...
