1. Thermophysical Modelling and Mechanical Stability of Cometary Nuclei
Sammanfattning : Comets are the most primordial and least evolved bodies in the Solar System. As such, they are unique sources of information regarding the early history of the Solar System. However, little is known about cometary nuclei since they are very difficult to observe due to the obscuring coma. LÄS MER
2. Adaptive Driver Information
Sammanfattning : New societal requirements and functional growth put new demand on future driver information. Simultaneously, new technology and IT capabilities makes it possible to constantly adapt the information given to the driver for different reasons. LÄS MER
3. Global energy transitions : Renewable energy technology and non-renewable resources
Sammanfattning : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. LÄS MER
4. Fit for European Democracy? : Party Discipline in the European Parliament
Sammanfattning : This study evaluates the fitness of political parties for the democratisation of the European Union. At the national level political parties have successfully functioned as transmission belts between voter’s preferences and political outcomes in representative democracies. LÄS MER
5. Bit loading and precoding for MIMO communication systems
Sammanfattning : This thesis considers the joint design of bit loading, precoding and receive filters for a multiple-input multiple-output (MIMO) digital communication system. Both the transmitter and the receiver are assumed to know the channel matrix perfectly. It is well known that, for linear MIMO transceivers, orthogonal transmission (i.e. LÄS MER
