1. Digital block transmission and time-of-flight estimation : receiver design and performance analysis
Sammanfattning : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. LÄS MER
2. Time of Flight Estimation for Radio Network Positioning
Sammanfattning : Trilateration is the mathematical theory of computing the intersection of circles. These circles may be obtained by time of flight (ToF) measurements in radio systems, as well as laser, radar and sonar systems. A first purpose of this thesis is to survey recent efforts in the area and their potential for localization. LÄS MER
3. Metabolic Studies with Liquid Separation Coupled to Mass Spectrometry
Sammanfattning : Metabolism is the sum of all chemical processes with the purpose to maintain life, as well as enable reproduction, in a living organism. Through the study of metabolism, increased understanding of pharmacological mechanisms and diseases can be achieved. LÄS MER
4. Quantitative Bioanalysis : Liquid separations coupled to targeted mass spectrometric measurements of bioactive compounds
Sammanfattning : Performing quantitative analysis of targeted bioactive compounds in biological samples, such as blood plasma, cerebrospinal fluid or extracts from pig liver, put high demands on the ruggedness of the method acquiring the results. In addition to the complexity of the sample matrix, the bioactive compounds targeted for analysis usually have low levels of natural abundance, further increasing the demand on the analytical method sensitivity.

5. Pharmaceutical and Biomedical Applications of Spectroscopy in the Photon Migration Regime
Sammanfattning : The present thesis is devoted to two different matters: One part is the development of a novel optical technique for characterisation of solid pharmaceutical materials. The other part being the continued development of photon time-of-flight spectroscopy, as well as exploration of new application areas of this method. LÄS MER
