1. Time-Frequency Analysis in Attosecond Spectroscopy
Abstract : This thesis deals with ultrafast dynamics of electronic processes in rare gas atoms. The processes we explore include photoemission, where we time the emission of electrons moving away from the atomic core following ionization by a photon; and auto-ionization, where the atom spontaneously releases an electron wave-packet following photo-excitation.

2. Discrete Stochastic Time-Frequency Analysis and Cepstrum Estimation
Abstract : The theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. READ MORE

4. Time-frequency analysis of atrial fibrillation
Abstract : This licentiate thesis, containing two papers, is in the field of biomedical signal processing with main focus on signal processing of the ECG in patients with atrial fibrillation (AF). The two papers deal with different aspects of characterization of the f waves during atrial fibrillation. READ MORE

5. Statistical inference and time-frequency estimation for non-stationary signal classification
Abstract : This thesis focuses on statistical methods for non-stationary signals. The methods considered or developed address problems of stochastic modeling, inference, spectral analysis, time-frequency analysis, and deep learning for classification. READ MORE
