Im da/sec scientific talk werden Forschungsergebnisse, die erst kürzlich veröffentlicht wurden oder es demnächst werden, am Fachbereich Informatik präsentiert. Wir möchten mit Studenten/innen, Mitarbeitern/innen und Professoren/innen über unsere Forschung diskutieren und freuen uns auf Feedback zur Präsentation. Die scientific talks sind einerseits Ergebnispräsentationen und andererseits gegenseitige Hilfen beim Probevortragen, was jeden Studierenden betrifft, spätestens zum Studiumende.
The da/sec scientific talk is a platform for discussing recent research results of our group with our faculty of computer science. We like to share our knowledge with our students, colleagues, and professors. Please feel free to join the talks and to discuss recent gains and presentation styles with us. Our scientific talks are not only results presentations, but also presentation rehearsals. Where, at the latest in the end of studies, presentation rehearsals affect all students as well.
