Bachelor and Master Theses
Physiological Sleep Analysis [VERSTECKT]
Bakk-/Masterarbeit vom 10. October 2013; offen

Problem definition, Approach:

  • Electrocardiogram (ECG) and related measures (HRV, autochronic image) offers great potential in person psychologic state change evaluation
  • Recreation while sleeping is an important topic
  • Sleep analysis: Influence of ECG measures of a couple
    a) both sleeping alone (e.g. in different rooms or flats/houses)
    b) sleeping together (double bed)

Expected outcome:

  • ECG/HRV/autochronic images show significant differences, e.g. more harmonic, counterbalanced, calm sleeping behavior when sleeping together compared to the situation of sleeping alone; "synchronization" of RR or ECG streams when sleeping together?


  • Interest in software/prototype development (Java, C/C++/C#)
  • User study: Setup and carry out several (maybe self) experiments
  • Good command of English (understanding of related work; Thesis is preferred written in English)
  • Typesetting using LaTeX (--> Miktex, TeXnicCenter) + BibTeX (-->Jabref)

Time schedule:

  • Start: flexible, as of now
  • Estimated completion date: within 12 months
