  1. 21. Nätverkskoordineringens dualiteter

    Författare :Fredrik Sjöstrand; Bo Hedberg; Ali Yakhlef; Mats Edenius; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; network; organization; coordination; mechanisms; Business studies; Företagsekonomi;

    Sammanfattning : By comparing intra- and interorganizational coordination, the purpose is to gain increased know-ledge of the mechanisms of coordination in network structures. The study is based on a longitudi-nal case study of coordination in a network structure, where coordination processes are taking place inside and between independent companies in a conveyor manufacturing industry.

  3. 22. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas

    Författare :Henrik Sjöstrand; Göran Ericsson; Johan Frenje; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; Fusion; Fusion;

    Sammanfattning : When the heavy hydrogen isotopes deuterium (D) and tritium (T) undergo nuclear fusion large amounts of energy are released. At the Joint European Torus (JET) research is performed on how to harvest this energy. Two of the most important fusion reactions, d+d→3He+n (En = 2.5 MeV) and d+t→4He+n (En = 14 MeV), produce neutrons. LÄS MER

  4. 23. Engineering superconducting qubits : towards a quantum machine

    Författare :Joachim Sjöstrand; Anders Karlhede; Denis Vion; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : A quantum computer is an information processing machine, much like an ordinary classical computer, but its function is based on quantum mechanical principles. To be able to construct such a machine would be a fantastic accomplishment---to have total control over a quantum system is a dream for both physicists and science-fiction enthusiasts. LÄS MER

  5. 24. Med älgen i huvudrollen : Om fångstgropar, hällbilder och skärvstensvallar i mellersta Norrland

    Författare :Ylva Sjöstrand; Anders Andrén; Kerstin Cassel; Lise Nordenborg Myhre; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Stone Age; Northern Sweden; Nämforsen; rock art; pit falls; mounds of burnt stone; affordances; James J. Gibsson; chronology; theories of meaning; key symbols; neolithisation; arkeologi; Archaeology;

    Sammanfattning : The importance of the elk (Alces alces) in the Stone Age societies of northern Sweden constitutes the major focus of this thesis. The point of departure is a simple but crucial observation: this animal is the common denominator between the three stationary types of remains known in this region from the period 4000-1800 BC.

  7. 25. Dewatering aspects at the forming section of the paper machine : Rewetting and forming fabric structure

    Författare :Björn Sjöstrand; Lars Nilsson; Christophe Barbier; David McDonald; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rewetting; forming fabric; forming section; dewatering; web dryness; high vacuum suction box; vacuum dewatering; forming fabric design; numerical model; Chemical Engineering; Kemiteknik;

    Sammanfattning : The underlying motives of the research undertaken here are twofold: to obtain a deeper understanding of the dewatering mechanisms at the forming section of a papermaking machine and to develop numerical models that describe the flow through forming fabrics. More comprehensive knowledge of dewatering in the forming section allows suggestions to be made for improvements that reduce the amount of energy used in the process without affecting the quality of the end product.
