I enjoy the teaching activity, and I assume it as the labor of communicating my own experience and reaffirming my own knowledge of the specific topics. Likewise, I have the feeling of connection with my students, and as a result, the success of each student is my primary goal.

The main aim of this course is to prepare the students on the basic aspects of the practical analysis of structural vibrations, with a perspective on real-life applications. The course topics include basics aspects of sensor and measurement systems and basic statistics for quality assessment of measured signals. Subsequently, the course focuses on the estimation of the power spectral density (PSD) of vibration signals and frequency response functions (FRFs) in input-output systems. Initially, the main focus is on non-parametric techniques based on Discrete Fourier Transform analysis, and finally, parametric methods based on time-series methods are introduced. Along with the lectures, the students will develop laboratory experiments, with the main aim of learning the practicalities of experimental vibration analysis with the help of different lab-size structures.

The main aim of this course is to develop the basic abilities for the analysis of structural vibrations. The course covers the analysis of Single and Multiple Degrees of Freedom (SDOF and MDOF) systems, and spatially-continuous systems. On each one of these topics, we initially study the free vibration response of each of those systems, and then we move into the response to harmonic excitations, which will lead to the concept of frequency response functions. Finally, the course introduces modal-domain analysis techniques, where MDOF systems are decoupled into a series of SDOF systems, associated with their own natural frequency and mode shape.

This course deals with the validation of structural dynamics models based on experimental vibration analyses, namely vibration data measured from a real structure. Initially, the course provides a brief overview of structural dynamics and techniques for measurement and processing of vibration signals. Then, the course focuses on parametric and non-parametric techniques for experimental and operational modal analysis, namely the identification of the modal properties of a structure based on measured vibration responses. Finally, the course explores different methods for validation of structural dynamics models and introduces techniques for updating structural dynamics models (FEM updating). The course includes two laboratory sessions aimed at collecting signals from a simple structure and validating an analytical model of the same structure.

This course deals with different basic aspects of signal analysis and signal processing, from a conceptual perspective amenable to audiology students, who have limited training on mathematics and physics. The aspects covered in this course include basic signal characteristics (amplitude, RMS amplitude, frequency, and phase), Fourier series analysis, power spectral density, and filters.
