Faglige interesser
- Signalprosessering av bevegelsesdata
- Maskinlæring og kunstig intelligens for prediksjon og risikoanalyser av bevegelsesrelaterte problemer
- Ikke-linære tidsserieanalyser med spesielt fokus på:
- Hilbert spektral analyser
- Wavelet analyser
- Multifraktale analyser
- Multiplikative kaskade modeller
- Lyapunov stabilitet
- Fraksjonell stabilitet
- Applikasjoner av analyser mot bevegelser hos eldre og spedbarn med risiko for motoriske problemer
Prosjekter
