Scientific Publications Related to Physiological Modeling, Signal Processing and Mathematical Modeling

The publications section presents studies where Firstbeat solutions have been exploited. The different scientific contexts include for example occupational health care, sleep research, psychotherapy, behavioral research, and sports coaching. Firstbeat methods have been used for research in over 100 universities and research institutions across Europe, North America, and Australia.
