Abstract: Signals generated by nonlinear dynamic systems are nonstationary. To analyze such signals using linear methods such, for example spectral or time-frequency methods, one has to have long signals, free of artifacts, denoised etc. Nonlinear analysis using Higuchi’s fractal dimension, Empirical Mode Decomposition, or symbolic methods is much better suited and should be used for such signals to extract important features of the nonlinear dynamic systems that generated analyzed signals. In particular, living organisma in general, and human organism is particular, are inherently nonlinear dynamic systems. That is why biosignals like EEG are inherently nonstationary, so our methods find application in medical diagnosis and in assessment of therapy results.

Brief Biography of the Speaker: Wlodzimierz Klonowski holds a Master of Science (M.S.) in Physics with specialization in Biophysics from the University of Warsaw (1968), Doctor of Philosophy (Ph.D.) from the Institute of Physics, Polish Academy of Sciences (1973), and Doctor of Science (D.Sc.) in Biophysics from Humboldt University, Berlin (1990). He has worked as a professor of Physics in the French-speaking l’Univesité National du Zaïre à Kinshasa, Republic of Congo, as a Max Planck Fellow at MPI fűr Biophysikalische Chemie in Goettingen, as a visiting professor at Brandeis University in Waltham, MA, as the President of Canadian Consulting and Tutoring Services at Halifax, NS, Canada. He has been a distinguished member of several organizations including Polish PhysicalSociety, European Physical Society, New York Academy of Sciences, American Association of University Professors, and American Association for the Advancement of Science. He is a Bio-Scientific Advisory Board Member of the International Brain Research Foundation Inc. New York, Vice-President and Board Member of the International Consortium for Nalecz Institute of Biocybernetics and Biomedical Engineering Polish Academy of Sciences in Warsaw, and is the Head of the Lab of Biosignal Analysis Fundamentals. He has been active for more than 40 years in the theory of complex nonlinear systems with applications in medicine and biology. He was an initiator and organizer of a series of European Summer Schools EUROATTRACTOR. He has contributed seriously to the theory of structureproperty relationships in crosslinked polymer materials through his topological theory of networks, so called Systems with Discrete Interactions. Currently, he is involved in the research on nonlinear methods of biosignal analysis and its applications for monitoring the depth of anesthesia and for assessment of medical therapies. Prof. Klonowski is the Founding Editor and an Editor-in-Chief of Nonlinear Biomedical Physics, an interdisciplinary open access journal (BioMed Central, London) that starting January 2013 is transformed into EPJ Nonlinear Biomedical Physics (Springer, Heidelberg) His biograms are included in several European and American Who’s Who’s, in Wikipedia, and he has a molecular informational structure named after him (Klonowski-Klonowska Conformon, term proposed by S.Ji in ‘Molecular Theories of Cell Life and Death’, Rutgers U. Press, 1991). W.Klonowski is also interested in philosophical problems, in particular in theory of consciousness, and emotions vs logical thinking, that he proposed to call Chaosensology.
