1. Estimation and Classification of Non-Stationary Processes : Applications in Time-Frequency Analysis
Abstract : This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated. READ MORE

2. Sparse Modeling of Harmonic Signals
Abstract : This thesis considers sparse modeling and estimation of multi-pitch signals, i.e., signals whose frequency content can be described by superpositions of harmonic, or close-to-harmonic, structures, characterized by a set of fundamental frequencies. READ MORE

3. Slotless High-Performance Electric Drives : Harmonic Loss Analysis, Sensorless Control, and Inverter Design
Abstract : Electric motor drives are a cornerstone for many fundamental functions in today’s society, and their expected dominance within the transport sector is considered one of the main keys to abate global warming. Subsequently, the incentives for improved performance of electric motor drives cannot be sufficiently emphasized. READ MORE

4. Modeling and Sampling of Spectrally Structured Signals
Abstract : This thesis consists of five papers concerned with the modeling of stochastic signals, as well as deterministic signals in stochastic noise, exhibiting different kinds of structure. This structure is manifested as the existence of finite-dimensional parameterizations, and/or in the geometry of the signals' spectral representations. READ MORE

5. Frequency Tracking for Speed Estimation
Abstract : Estimating the frequency of a periodic signal, or tracking the time-varying frequency of an almost periodic signal, is an important problem that is well studied in literature. This thesis focuses on two subproblems where contributions can be made to the existing theory: frequency tracking methods and measurements containing outliers. READ MORE
