Anna Krakovská, SAS

Work and study

1987 - MSc. in mathematics, Faculty of Mathematics and Physics, Comenius University in Bratislava and start of work at Institute of Measurement Science SAS
1993 - PhD. in bionics (thesis titled Nonlinear dynamics of selected biological systems)

Current research interests

Methods of nonlinear dynamics in signal processing:

• signal and time series analysis by methods of nonlinear dynamics; applications to complex physiological systems - reconstruction of multi-dimensional state portraits, noise reduction, modeling, prediction, study of causal relations
• biological signals processing (ECG, EEG)
• complexity estimation using measures known from the fractal theory and theory of chaos
