    Sammanfattning : Bit-interleaved coded modulation (BICM) was introduced in 1992 as a new coded modulation (CM) scheme particularly well suited for fading channels and is nowadays considered the de facto CM scheme in wireless standards (HSPA, IEEE 802.11a/g/n, DVB-T2/S2/C2, etc.). LÄS MER

  3. 2. State Steering and Traditional Ecological Knowledge in Reindeer-Herding Governance : Cases from western Finnmark, Norway and Yamal, Russia

    Författare :Ellen Inga Turi; Carina Keskitalo; Dieter Müller; Dietrich Soyez; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; reindeer pastoralism; multi-level governance; state steering; traditional ecological knowledge; western Finnmark northern Norway ; Yamal northwest Siberia ;

    Sammanfattning : The Arctic regions are currently undergoing transformative changes linked to globalization and climate change, which pose challenges for current governance structures. This thesis investigates governance in times of change through the lens of reindeer pastoralism, and the traditional ecological knowledge (TEK)- based management in reindeer herding. LÄS MER

  4. 3. The Emerging Outer Space Order : Professional Orders, Heterarchy, Hypermodernity and Political Reason

    Författare :Lisa Justesen; Statsvetenskapliga institutionen; []

    Sammanfattning : Political order in outer space has so far been perceived as an extension of the terrestrial political order. In contrast, I argue that the political order emerging in outer space defines international relations on Earth. LÄS MER

  5. 4. Det är inte bara att lägga schema : implementeringsformer vid in- och genomförande av flexibla arbetstidsmodeller i kommunernas sociala omsorgsverksamheter

    Författare :Marianne Westring-Nordh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Man Machine Relation Focusing Gender; Människa-maskin med inriktning mot genusforskning;

    Sammanfattning : This dissertation proceeds from studies of introduction and realization of flexible working hour models in municipal social care. It includes two empiric studies, the deep study that covers one flexible working hour model that has been realized in one municipality's care administration. LÄS MER

  7. 5. Novel FISH methods to unveil genome architecture

    Författare :Ana Mota; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The genome consists of incredibly long DNA strands that encode all the vital information for the cell to function. The DNA inclusion in the very tight nuclear space and, simultaneously, the establishment of a hierarchical organization of the chromatin that favors transcription of certain genes over others, sparked a long-lasting quest to understand the design principles that govern genome architecture.
