SCCS Colloquium

The SCCS Colloquium is a forum giving students, guests, and members of the chair the opportunity to present their research insights, results, and challenges. Do you need ideas for your thesis topic? Do you want to meet your potential supervisor? Do you want to discuss your research with a diverse group of researchers, rehearse your conference talk, or simply cheer for your colleagues? Then this is the right place for you (and you are also welcome to bring your friends along).

Nikola Wullenweber: Development of a Testing Framework for the Quantitative Analysis of the Quality within Computational Models

SCCS Colloquium |


Computational models are an important tool for simulating phenomena in science and engineering.
One industry standard for exchanging these models is the Functional Mock-up Interface (FMI), which allows exporting models as a Functional Mockup Unit (FMU). This standard allows engineers to connect third-party models and perform co-simulation with specialized tools. However, it can be hard to find out whether a model produces the desired output, especially when it is a black-box model. Therefore, there is a need for good ways of testing the correct behavior of such a model. The curse of dimensionality especially complicates this, because it can lead to extremely high runtimes when sampling black-box models.
In this work, I want to find out whether sensitivity analysis methods are useful to analyze black-box models that are implemented via the FMI standard.
For the screening and the analysis, SAlib is used, which is an open-source Python library implementing the Sobol Method and the Morris Screening methods among others. These methods help us to determine the quality of a model for a broad range of inputs with a rough screening and to analyze the relationship between inputs and outputs in a quantitative fashion.
For testing the implementation, I used two different simulation models: First, a model of a one-dimensional spring equation and, second, a battery model provided by simercator GmbH for a case study. I use the language Modelica to create FMUs and the Python library fmpy to simulate them.

IDP presentation. Nikola is advised by Benjamin Rodenberg.

Contribute a talk

To register and schedule a talk, you should fill the form Colloquium Registration at least two weeks before the earliest preferred date. Keep in mind that we only have limited slots, so please plan your presentation early. In special cases, contact colloquium@mailsccs.in.tum.de.

You can try the platform beforehand using Try BigBlueButton, or by starting your own room at the RBG BBB. For troubleshooting, you could also try the WebRTC Troubleshooter.

Note: Starting from October, Colloquium sessions will be on-campus. We have booked room MI 00.13.054. You can either bring your own laptop (please bring your own adapters) or send us the slides as a PDF ahead of time.

We invite students doing their Bachelor's or Master's thesis, as well as IDP, Guided Research, or similar projects at SCCS to give one 20min presentation to discuss their results and potential future work. The time for this is typically after submitting your final text. Check also with your study program regarding any requirements for a final presentation of your project work.

New: In regular times, we will now have slots for presenting early stage projects (talk time 2-10min). This is an optional opportunity for getting additional feedback early and there is no strict timeline.

Apart from students, we also welcome doctoral candidates and guests to present their projects.

During the colloquium, things usually go as follows:

  • 10min before the colloquium starts, the speakers setup their equipment with the help of the moderator. The moderator currently is Irene López. Make sure to be using an easily identifiable name in the online session's waiting room.
  • The colloquium starts with an introduction to the agenda and the moderator asks the speaker's advisor/host to put the talk into context.
  • Your talk starts. The scheduled time for your talk is normally 20min with additional 5-10min for discussion.
  • The moderator keeps track of the time and will signal 2min before the end of time (e.g. by turning on their video).
  • During the discussion session, the audience can ask questions, which are meant for clarification or for putting the talk into context. The audience can also ask questions in the chat.
  • Congratulations! Your talk is over and it's now time to celebrate! Have you already tried the parabolic slides that bring you from the third floor to the Magistrale?

Do you remember a talk that made you feel very happy for attending? Do you also remember a talk that confused you? What made these two experiences different?

Here are a few things to check if you want to improve your presentation:

  • What is the main idea that you want people to remember after your presentation? Do you make it crystal-clear? How quickly are you arriving to it?
  • Which aspects of your work can you cover in the given time frame, with a reasonable pace and good depth?
  • What can you leave out (but maybe have as back-up slides) to not confuse or overwhelm the audience?
  • How are you investing the crucial first two minutes of your presentation?
  • How much content do you have on your slides? Is all of it important? Will the audience know which part of a slide to look at? Will somebody from the last row be able to read the content? Will somebody with limited experience in your field have time to understand what is going on?
  • Are the figures clear? Are you explaining the axes or any other features clearly?

In any case, make sure to start preparing your talk early enough so that you can potentially discuss it, rehearse it, and improve it.
