zum Forschungsseminar 'Computergrafik, Bildverarbeitung und Visualisierung'

     am Mittwoch, den 13. Juli 2022, 13:15 Uhr,
     im Raum P-701 im Paulinum am Augustusplatz, sowie über eine 
Webkonferenz.

Wir hören einen Vortrag von

     Arne Präger

mit dem Titel:

     'Visualizing Statistical Complexity in 3D Turbulent Flows using a 
Robust Entropy Calculation Method'

zum Inhalt:

     Highly resolved flow simulation data is becoming more common. These
     simulations frequently feature high turbulence with complex flow 
patterns.
     Finding these regions often requires expert knowledge, and in more 
complex
     cases, flow patterns of interest may remain hidden. The concept of
     statistical complexity was shown to be suitable to indicate regions of
     interest within flow data with limited prior knowledge. One way to
     determine the statistical complexity of flow fields is via the local
     vector field entropy and the correlation. In this work, we improve the
     method for calculating the Shannon entropy in vector fields. To this
     end, we introduce a robust entropy computation that takes the scale of
     the corresponding regions into account. The improved method uses a 
novel
     way to determine the distributions required for the entropy calculation
     and is applicable to unstructured domains. We validate our method with
     analytic flow fields and apply it to fluid simulation data, visualizing
     the results via volume rendering. This work shows the applicability of
     our technique to highlight regions of interest in turbulent flows.

Weiterhin, hören wir einen Vortrag von

     Michelle Kampfrath

mit dem Titel:

     'MDsrv: visual sharing and analysis of molecular dynamics simulations '

zum Inhalt:

     Molecular dynamics simulation is a proven technique for computing and
     visualizing the time-resolved motion of macromolecules at atomic 
resolution.
     The MDsrv is a tool that streams MD trajectories and displays them
     interactively in web browsers without requiring advanced skills,
     facilitating interactive exploration and collaborative visual analysis.
     We have now enhanced the MDsrv to further simplify the upload and 
sharing
     of MD trajectories and improve their online viewing and analysis. With
     the new instance, the MDsrv simplifies the creation of sessions, which
     allows the exchange of MD trajectories with preset representations and
     perspectives. An important innovation is that the MDsrv can now access
     and visualize trajectories from remote datasets, which greatly expands
     its applicability and use, as the data no longer needs to be accessible
     on a local server. In addition, initial analyses such as sequence or
     structure alignments, distance measurements, or RMSD calculations have
     been implemented, which optionally support visual analysis. Finally,
     based on Mol*, MDsrv now provides faster and more efficient 
visualization
     of even large trajectories compared to its predecessor tool NGL.
