1. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems
Sammanfattning : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. LÄS MER
2. MIMO Channels - Measurements and Analysis
Sammanfattning : Providing increased transmission speed, quality and an efficient spectrum utilization is crucial for high speed wireless services of today and the future. This thesis is a collection of papers that address an important step in that direction -- the utilization of the spatial domain of the wireless channel. LÄS MER
3. Multi-Level Lossless Phase Modulation in Liquid Crystals for High-Speed Spatial Light Modulators
Sammanfattning : The spatial light modulator (SLM) is a compact device that enables highly precise control of light propagation with low drive voltages and no moving parts. By imposing a certain phase modulation onto the incident lightwave, functions such as multi-beam steering, beam shaping, and air turbulence corrections can be achieved in realtime. LÄS MER
4. Catanionic Surfactant Mixtures and Binary Systems of Modified Fatty Acid Surfactants. Phase Equilibria and Structure
Sammanfattning : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

5. Phase Noise in Communication Systems--Modeling, Compensation, and Performance Analysis
Sammanfattning : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. LÄS MER
