  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

    Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

  5. 4. Towards Unifying Stream Processing over Central and Near-the-Edge Data Centers

    Författare :Hooman Peiro Sajjad; Vladimir Vlassov; Johan Tordsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geo-distributed stream processing; geo-distributed infrastructure; edge computing; edge-based analytics; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In this thesis, our goal is to enable and achieve effective and efficient real-time stream processing in a geo-distributed infrastructure, by combining the power of central data centers and micro data centers. Our research focus is to address the challenges of distributing the stream processing applications and placing them closer to data sources and sinks. LÄS MER

  7. 5. The Quest for Edge Awareness, Lessons not yet learned : PhD Thesis on practical and situated usefulness of advanced technological systems among inescapable uncertainties and competing interests in a world of dynamic changes

    Författare :Patrik Stensson; Anders Jansson; Pär Ågerfalk; Martin Norsell; Erik Hollnagel; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; critical realism; human factors; situation awareness; resilience engineering; human-machine interaction; automation; autonomy; situated usefulness; systems thinking; sociotechnical systems; edge awareness; Människa-dator interaktion; Human-Computer Interaction;

    Sammanfattning : This thesis problematizes the concept of usefulness, in part by taking questions to the extreme. The starting point is the contemporary view of usefulness, a view that remains within a traditional paradigm of technical rationality in which important aspects are disregarded or not perceived because they are not part of the equation.
