  1. 11. Signal Enhancement in Wireless Communication Systems

    Författare :Jörgen Nordberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel equlization; Multirate Equalization; Signal Separation; Beamforming; Sptial Equalization;

    Sammanfattning : Digital Wireless communications has been one of the fastest growing communication techniques during the last decade. Today there exists several different communication systems that use wireless techniques. They share one common property that they transmit data through a radio interface. LÄS MER

  3. 12. URBAN SEGREGATION AND URBAN FORM : From residential segregation to segregation in public space

    Författare :Ann Legeby; Lars Marcus; Eva Öresjö; Anna-Johanna Klasander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban segregation; urban form; urban design; housing segregation; residential segregation; public space; co-presence; public life; spatial affordance; Architecture; Arkitektur;

    Sammanfattning : Urban segregation is considered a major social problem in Sweden and several national anti-segregation initiatives have been launched to decrease social and ethnic segregation but so far only with marginal effects (SOU 2005:29). Urban design and town planning are rarely the focus in national anti-segregation initiatives; the architectural issue has mainly been confined to matters concerning housing policies. LÄS MER

  4. 13. Fritidshuset som planeringsdilemma

    Författare :Ingrid Persson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple dwelling; planning dilemma; spatial planning; legislation; secondary home; municipality planning; natural resources; advertisement; estate agent; Lefebvre; Laclau; Mouffe;

    Sammanfattning : The thesis The Vacation House as a Planning Dilemma deals with how the processes that generate meaning in space proceed in parallel both in everyday life and in the planning realm. Multiple dwelling, or having two homes, can be seen as a dilemma—one in which the planning system’s attempts to conquer an unruly reality conflicts with the ways people live. LÄS MER

  5. 14. Spatio-temporal processing of surface electromyographic signals : information on neuromuscular function and control

    Författare :Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; multichannel surface electromyography; motor unit action potentials; conduction velocity; muscle architecture; signal quality; spatial distributions; synchronization; muscle function; motor control; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). LÄS MER

  7. 15. Large Eddy Simulation of the Flow around a High-Lift Airfoil

    Författare :Simon Dahlström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mildly separation; hybrid RANS LES; incompressible finite volume; airfoil; transition; large Eddy simulation; approximate wall boundary condition;

    Sammanfattning : The work presented in this thesis concerns the efforts of conducting a Large Eddy Simulation (LES) around an airfoil. The airfoil is close to stall, near maximum lift and the Reynolds number is high. In the flow a transitional separation bubble is present. LÄS MER
