6. On angiogenesis modulation
Sammanfattning : During evolution, the transition from unicellular to multicellular organisms required the origin of a transport system capable of interconnecting specialized cells throughout the body of the organism. In higher animals, this route of transportation is the cardiovascular system, which allows gas exchange, and transport of immune cells, hormones, macromolecules, nutrients and waste products. LÄS MER
7. Modulation of Modular Multilevel Converters for HVDC Transmission
Sammanfattning : The outstanding features of modular multilevel converters (MMC) have recently gained much attention in the high-voltage direct-current (HVDC) transmission field. Power quality, converter cost and system performance are three crucial aspects of HVDC MMCs which are directly linked to the converter modulation and switching schemes. LÄS MER
8. Control, Modulation and Implementation of Modular Multilevel Converters
Sammanfattning : Denna avhandling behandlar analys och styrning av den modulära multinivå omvandlaren (M2C). M2C är en lovande omvandlarteknologi för högspända högeffekttillämpningar. Anledningen till detta är låg distorsion i utstorheterna kan uppnås med låg medelswitchfrekvens per switch och utan utgångsfilter. LÄS MER
9. Biochemical and biomechanical modulation of the in vitro retina
Sammanfattning : The porcine retinal explant culture paradigm offers the possibility to study retinal health, disease and development independently from the surrounding tissues of the eye. Retina-intrinsic effects of molecular and mechanical cues on the isolated retinal sheet can thus be studied with great precision. LÄS MER
10. On Bit-Wise Decoders for Coded Modulation
Sammanfattning : Coded modulation is a technique that emerged as a response to the growing demand for high data rates. It was devised to achieve high spectral efficiency with high reliability, potentially approaching Shannon’s capacity. The main idea of coded modulation consists in combining error-correcting coding with higher-order modulation. LÄS MER
