Study, bachelor and master theses

Are you looking for a student research project or a thesis?

We constantly have practical and interesting work to assign. These include research and development work, as well as topics that can be handled without prior tribology knowledge, such as design, programming, metrology and data research.

Industry collaborations

Much of the work is carried out in collaboration with companies in the region. In this way, you can already make contacts during your studies, which may make it easier for you to start your career.

Theses (Bachelor/Master)

Evaluation of standstill markers by means of machine learning

Machine learning, programming

Machine learning is to be used to automatically classify so-called standstill marks on rolling bearings. In the optimum case, a prediction of the wear depth is also possible.
Python or Matlab can be used for this purpose.

  • Automatic reading of the images
  • Find and modify suitable code as a basis.
    These can be a) classical methods of image processing, where the user himself finds features, which are then assigned to classes using classical classifiers (decision tree, support vector machine, k-nearest neigbour, etc.), or
    b) one chooses an artificial neural network, which has already proven itself for image classification, and tries to train it with many classified (labeled) images.
  • Prediction of wear depth based on image features
  • Written elaboration in Word

Good knowledge of Matlab or Python.

Interest in working out solutions independently (problem-solving skills).
