  1. 1. An Inexplicable Hunger – flutist)body(flute (dis)encounters

    Författare :Marina Cyrino; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; flute practices; flutist; performance; composition; improvisation; artistic research; musicianship; standardisation; specialisation; fragmentation; co-creation; collaborative processes; encounters; mixture; mixed practices; multimodal practices; metamorphosis; transdisciplinarity; transversality; flexible subjectivity; processual subjectivity; politics of subjectivation; otherness; othering; resonant body;

    Sammanfattning : This doctoral research is structured by singular encounters, that happened between 2014 and 2018. Together with a series of collaborators, I have developed a critical and poetic methodology through what I call “mixture”, “contamination” and the practice of “un-goaling”, in which my “flutist-body-flute” relation encounters the practices of other artists.

  2. 2. High-Efficiency SiC Power Conversion : Base Drivers for Bipolar Junction Transistors and Performance Impacts on Series-Resonant Converters

    Författare :Georg Tolstoy; Hans-Peter Nee; Stig Munk-Nielsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide; Bipolar Junction Transistor BJT ; Resonant converter; Series-resonant converter SLR ; Base drive circuits; High- Efficiency Converters; High-Frequency Converters; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis aims to bring an understanding to the silicon carbide (SiC) bipolar junction transistor (BJT). SiC power devices are superior to the silicon IGBT in several ways. They are for instance, able to operate with higher efficiency, at higher frequencies, and at higher junction temperatures. LÄS MER

  3. 3. Three-body Universality Controlled by a Feshbach Resonance

    Författare :Kajsa-My Tempest; Svante Jonsell; Doerte Blume; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Efimov states; few-body systems; ultracold atoms; van der Waals interaction; Feshbach resonances; universality; computational studies; Theoretical Physics; teoretisk fysik;

    Sammanfattning : The quantum Efimov effect manifests itself in the limit of resonant two-body interactions, where the scattering length diverges. In this scenario, an infinite number of shallow bound trimer states are formed with binding energies that obey a discrete geometric scaling law. LÄS MER

  4. 4. Cluster Effective Field Theory

    Författare :EMIL RYBERG; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; effective field theory; charge radius; resonant state; renormalization; radiative capture; halo nuclei; power counting; nuclear physics; few-body physics;

    Sammanfattning : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. LÄS MER
