1. 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

2. 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.

4. Measurements and Modelling of Low-frequency Disturbances in Induction Machines
Abstract : in this thesis the low-frequency dynamic behavior of the induction machine is analyzed. disturbances in the shaft torque and supply voltage are investigated theoretically, The calculated response to shaft torque disturbances is verified with measurements on a 15 kW machine. READ MORE

5. Electroglottographic analysis of phonatory dynamics and states
Abstract : The human voice is a product of an intricate biophysical system. The complexity of this system enables a rich variety of possible sounds, but at the same time poses great challenges for quantitative voice analysis. For example, the vocal folds can vibrate in several different ways, leading to variations in the acoustic output. READ MORE
