1. Skeletal muscle in Restless legs syndrome (RLS) and Obstructive sleep apnoea syndrome (OSAS)
Sammanfattning : Restless legs syndrome (RLS) and Obstructive sleep apnoea syndrome (OSAS) are two sleep disorders that affect daily life with symptoms such as sleepiness and fatigue. It was therefore hypothesised that the skeletal muscle could be affected as symptoms from skeletal muscle are common. LÄS MER
2. Combating Intersymbol Interference and Cochannel Interference in Wireless Communication Systems
Sammanfattning : Over the last decade the world has witnessed explosive growth in the use of wireless mobile communications. Looking around we find users with mobile phones, wireless PDAs, pagers, MP3 players, and wireless headphones to connect to these devices - a small testament of the impact of wireless communications on our daily lives.

3. Control of Energy Storage Equipped Shunt-connected Converter for Electric Power System Stability Enhancement
Sammanfattning : Flexible AC Transmission System (FACTS) controllers, both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the FACTS controllers family, the Static Synchronous Compensator (STATCOM) is a key device for the reinforcement of the stability in an AC power system. LÄS MER
4. Power System Stability Enhancement Using Shunt-connected Power Electronic Devices with Active Power Injection Capability
Sammanfattning : Power electronic devices such as Flexible AC Transmission Systems (FACTS), both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the shunt-connected FACTS controllers family, the Static Synchronous Compensator (STATCOM) and the Static Var Compensator (SVC) are two key devices for reinforcing the stability of the AC power system.

5. Stereophonic Acoustic Echo Cancellation: Theory and Implementation
Sammanfattning : The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. LÄS MER
