1. High resolution time-frequency representations
Sammanfattning : Non-stationary signals are very common in nature, e.g. sound waves such as human speech, bird song and music. It is usually meaningful to describe a signal in terms of time and frequency. LÄS MER
2. Spectral Analysis for Signal Detection and Classification : Reducing Variance and Extracting Features
Sammanfattning : Spectral analysis encompasses several powerful signal processing methods. The papers in this thesis present methods for finding good spectral representations, and methods both for stationary and non-stationary signals are considered. LÄS MER
3. Radio Channel Prediction Based on Parametric Modeling
Sammanfattning : Long range channel prediction is a crucial technology for future wireless communications. The prediction of Rayleigh fading channels is studied in the frame of parametric modeling in this thesis.Suggested by the Jakes model for Rayleigh fading channels,deterministic sinusoidal models were adopted for long rangechannel prediction in early works.

4. Functional dynamics of glycosyltransferases : Solution-state NMR studies of peripheral membrane proteins involved in glycolipid biosynthesis in bacteria
Sammanfattning : Antibiotic resistance is an existential threat enabled by bacterial adaptation and fuelled by inappropriate use of medication. The ensuing shortage of effective treatments has led to a rise in deaths linked to resistant bacterial pathogens. LÄS MER
5. Control of neuronal survival, migration and outgrowth by GDNF and its receptors
Sammanfattning : Glial cell line-derived neurotrophic factor (GDNF) is the prototypical member of a family of growth factors that are indispensable in nervous system development and maintenance. GDNF signals by binding to a multi-component receptor complex comprised of the ligand-binding subunit GFRα1 and the signaling subunit RET or NCAM. LÄS MER
