Development and implementation of novel measurement techniques and analysis of different types of data mainly originating from real-life sources. The research based on theoretical and experimental investigation, covering all phases of the measurement and analysis processes (measurement hardware development, data acquisition, data processing and storage using dedicated expert programs and algorithms). Gathering of data series appropriate for statistical evaluation (long memory processes statistics), nonlinear features detection (self-affine structures, chaotic behavior etc ...) and system functional features interpretation. Knowledge for scientific advancement in various progressive areas such as real-system modeling, complex electronic circuits’ behavior research, new communication technologies, bioinformatics and particular areas of medical information systems.
