  2. 1. Thermophysical Modelling and Mechanical Stability of Cometary Nuclei

    Author : Björn Davidsson; Dina Prialnik; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Comets; Tidal physics; Light scattering; Radiative transfer; Thermophysics; Gas kinetics; Non-gravitational forces; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Theoretical Astrophysics; teoretisk astrofysik;

    Abstract : 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. READ MORE

  4. 2. Adaptive Driver Information

    Author : Staffan Davidsson; Björn Peters; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk psykologi; Engineering Psychology;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  6. 4. Fit for European Democracy? : Party Discipline in the European Parliament

    Author : Björn Lindberg; Sverker Gustavsson; Sven Oskarsson; Lars Davidsson; Simon Hix; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; European Parliament; democracy; political parties; collective action; legislative decision-making; party discipline; party voting cohesion; Political science; Statsvetenskap;

    Abstract : 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. READ MORE

  7. 5. Bit loading and precoding for MIMO communication systems

    Author : Svante Bergman; Björn Marklund; Tim Davidsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : 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. READ MORE
