16. Multiport Antenna Systems for Space-Time Wireless Communications
Sammanfattning : Multiport antenna systems are indispensable part of modern wireless communication systems. Their crucial impact on the overall performance requires sufficient regard and dedication to a precise design and characterisation. This concern has been to a considerable extent addressed in the frame of the current thesis. LÄS MER
17. Ecology of zooplankton communities: climate, dormancy, and benthic-pelagic coupling
Sammanfattning : This thesis describes how influences, such as top down and bottom up forces, shape zooplankton communities in shallow lakes. I have also extended the traditional food-web theory by investigating the effects of climate on total biomass, taxonomic composition, and temporal properties of zooplankton communities. LÄS MER
18. Temporal and spatial variation in the community composition of lake bacterioplankton
Sammanfattning : Bacterioplankton are among the smallest and most abundant organisms in lake ecosystems. Due to the lack of relevant methods, the taxonomic composition of bacterioplankton has been studied less thoroughly than that of larger organisms. LÄS MER
19. Spatial Characterization and Estimation of Intracardiac Propagation Patterns During Atrial Fibrillation
Sammanfattning : This doctoral thesis is in the field of biomedical signal processing with focus on methods for the analysis of atrial fibrillation (AF). Paper I of the present thesis addresses the challenge of extracting spatial properties of AF from body surface signals. LÄS MER
20. The influence of trophic polymorphisms on habitat coupling in aquatic food webs
Sammanfattning : Trophic cascades, together with other indirect interactions are important aspects in shaping the composition and abundance of species in the food web. Theoretically, movement of energy between systems, and coupling between habitats by mobile predators have been suggested as being important for food web stability and evenness. LÄS MER
