  2. 1. 11B4C containing Ni/Ti neutron multilayer mirrors

    Author : Sjoerd Broekhuijsen; Fredrik Eriksson; Jens Birch; Thierry Bigault; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The work in this thesis covers the design, growth and characterisation of neutron multilayers. The performance of these multilayers is highly dependent on the obtained interface width between the layers, even a modest improvement can offer a substantial increase in reflectivity performance.

  4. 2. Assessment of dopamine and serotonin release in the non-human primate brain using PET

    Author : Sjoerd J. Finnema; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The molecular imaging technique positron emission tomography (PET) allows for non-invasive examination of biochemical markers in the living brain. For over three decades PET studies have provided important insight into the relationship of monoaminergic neurotransmitter systems to brain functioning and psychiatric disorders. READ MORE

  5. 3. Assembly of microsystems for optical and fluidic applications

    Author : Sjoerd Haasl; Göran Stemme; Richard Syms; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; microsystem technology; micromachining; assembly; active alignment; BCB; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : This thesis addresses assembly issues encountered in optical and fluidic microsystem applications. In optics, the first subject concerns the active alignment of components in optical fibersystems. READ MORE

  6. 4. Multilayer neutron optics based on isotope-enriched 11B4C

    Author : Sjoerd Stendahl; Jens Birch; Fredrik Eriksson; Artur Gregor Glavic; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The work in this thesis covers the design, growth and characterisation of neutron multilayers. The achieved reflectivity performance of a neutron multilayer depends on the achieved optical contrast between the layers as well as the achieved interface width between the layers. READ MORE

  7. 5. Traces of Hecke operators on Drinfeld modular forms via point counts

    Author : Sjoerd De Vries; Jonas Bergström; Gunther Cornelissen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinfeld modules; Drinfeld modular forms; trace formula; Ramanujan bound; slopes; matematik; Mathematics;

    Abstract : In this licentiate thesis, we study the action of Hecke operators on Drinfeld cusp forms via the theory of crystals over function fields. The thesis contains one preliminary chapter, in which we recall some basic theory of Drinfeld modules and Drinfeld modular forms, as well as the Eichler-Shimura theory developed by Böckle. READ MORE
