  2. 2. Welfare state attitudes in context : local contexts and attitude formation in Sweden

    Författare :Ingemar Johansson Sevä; Stefan Svallfors; Jonas Edlund; Joakim Palme; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Welfare state; attitudes; local context; municipalities; multilevel analysis; Sweden; Sociology; Sociologi; sociologi; Sociology;

    Sammanfattning : Welfare state attitudes are often studied from the perspective of the individual's characteristics and/or national or regime-type contexts. This thesis instead seeks explanations for individuals' varying attitudes towards the welfare state at the level of local contexts (municipalities). LÄS MER

  3. 3. Voices from the welfare state. Dissatisfaction and political action in Sweden

    Författare :Maria Solevid; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; political action; dissatisfaction; welfare state; policy feedback; institutions; empowerment; political participation; Sweden;

    Sammanfattning : The aim of this study is to investigate the relationship between citizens’ dissatisfaction with the welfare state and political action on welfare state issues, and to what extent institutional arrangements affects this relationship. The point of departure for this study is the policy feedback perspective, which acknowledges that the design of institutions shape and constrain citizens’ political preferences and behaviors.

  4. 4. Limited Feedback Information in Wireless Communications : Transmission Schemes and Performance Bounds

    Författare :Thanh Tùng Kim; Mikael Skoglund; Hesham El Gamal; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diversity-multiplexing tradeoff; Large deviation analysis; Limited feedback; MIMO channels; Relay channels; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis studies some fundamental aspects of wireless systems with partial channel state information at the transmitter (CSIT), with a special emphasis on the high signal-to-noise ratio (SNR) regime. The first contribution is a study on multi-layer variable-rate communication systems with quantized feedback, where the expected rate is chosen as the performance measure. LÄS MER

  5. 5. Feed-forward Control and Dynamic Modelling in Temperature Control of Buildings

    Författare :Mohsen Soleimani-Mohseni; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building models; state space models; feedback; thermostats; transfer function models; intelligent buildings; ON-OFF controllers; Feed-forward; PIL controllers;

    Sammanfattning : This thesis is mainly about the investigations of different control strategies (and in particular feed-forward) in order to improve indoor climate and/or save energy in buildings. One part of the thesis deals with different ways to obtain dynamic models for climate systems in buildings. LÄS MER
