1. Control and Communication with Signal-to-Noise Ratio Constraints
Sammanfattning : This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. LÄS MER
2. On the Adaptive Array Problem
Sammanfattning : By an array we mean a set of coupled sensors, typically antenna elements. The array receives superimposed signals from distant sources. By combining the outputs of the sensors in different ways, one can change the array sensitivity to different Directions-of-Arrival (DOA). LÄS MER
3. Local Sea Level Observations Using Reflected GNSS Signals
Sammanfattning : Sea level rise due to global warming is predicted to have a large impact on human society, especially for populations living in coastal regions and on islands. It is therefore of great importance to monitor the sea level and to increase the understanding of the local hydrodynamic and meteorological responses to a global sea level rise. LÄS MER
4. Computerised Microtomography : Non-invasive imaging and analysis of biological samples, with special reference to monitoring development of osteoporosis in small animals
Sammanfattning : The use of Computerised microtomography (CμT) in biomedical research is well established, with most applications developed at synchrotron facilities. The possibility to non-invasively monitor morphological changes in biological samples, makes it an attractive technique in biomedicine. LÄS MER
5. Search for Type 2 Diabetes Susceptibility Genes Using Multiple Approaches
Sammanfattning : Type 2 diabetes mellitus is a multifactorial disorder characterized by chronic hyperglycemia resulting from pancreatic dysfunction and insulin resistance. It is a common disorder with a complex pattern of inheritance, likely to reflect the influence of multiple genetic and environmental factors on the diabetes risk. LÄS MER
