  1. 1. De fyra elementen : En semantisk motivstudie i Gunnar Ekelöfs En Mölna-Elegi

    Författare :Ulf Larsson; Staffan Hellberg; Gunnar Persson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; lexical semantics; semantic frame theory; literary stylistics; poetry; Riffaterre; matrix; Barsalou; Swedish; Scandinavian languages; Nordiska språk;

    Sammanfattning : The aim of this study is to examine the semantic architecture of the motif complex the four elements, i.e. fire, air, water and earth, in the Swedish poet Gunnar Ekelöf’s poem A Mölna Elegy (1960). The poem belongs to the same polyphonic and quotative-allusive tradition as T. LÄS MER

  3. 2. Cognitive Radio Networks : Elements and Architectures

    Författare :Alexandru Popescu; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cognitive radio network management; spectrum access; multiconstrained routing optimization; multi-dimensional adaptation; middleware;

    Sammanfattning : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop. LÄS MER

  4. 3. Periodic structures and lumped elements in microwave passives

    Författare :Dan Kuylenstierna; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Passive elements; Lumped elements; Photonic bandgap; Metamaterial; MMIC; Electromagnetic bandgap; Ferroelectric; Quadrature hybrid; Quadrature power splitter; Balun; Periodic structures;

    Sammanfattning : The ambition of this work is the incorporation of ferroelectric varactors as tuneable elements in Si integrated circuits (ICs). This thesis presents partialfulfillments of the work. LÄS MER

  5. 4. Transposable Elements in Neural Progenitor Cells

    Författare :Liana Fasching; Molekylär neurogenetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transposable Elements; TRIM28; Epigenetic Regulation; Gene Expression; Neural Progenitor Cells;

    Sammanfattning : More than 90% of DNA does not code for proteins and for a long time these sequences were referred to as “junk DNA” due to their unknown purpose. With the advent of new technologies it is now known, that the non-coding part of the genome is of great importance for regulating gene expression and is therefore indispensable. LÄS MER

  7. 5. Population Genetics of Human Genomic Elements

    Författare :Thijessen Naidoo; Mattias Jakobsson; Guillaume Achaz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; human genome; functional elements; natural selection; pseudogenes; loss-of-function; gene regulation; Y chromosome; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. LÄS MER
