  2. 1. On the phase behaviour of hydrogels : A theory of macroion-induced core/shell equilibrium

    Author : Jonas Gernandt; Per Hansson; Göran Frenning; Renko de Vries; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polymer; polyelectrolyte; surfactant; thermodynamics; elasticity; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Colloidal macroions are known to interact very strongly with oppositely charged polyionic hydrogels. Sometimes this results in a non-uniform distribution of the macroions within the gel, a phenomenon that is not fully understood. READ MORE

  4. 2. 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

  5. 3. Here be monsters: Investigating sociotechnical interaction in safety-critical work in the maritime domain

    Author : Linda de Vries; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pilotage; Functional Resonance Analysis Method FRAM ; e-navigation; safety; Resilience Engineering; Vessel Traffic Services VTS ; Human Factors; sociotechnical systems;

    Abstract : Maritime Pilots and Vessel Traffic Services (VTS) operators work to improve the safety of navigation of seagoing vessels. As in many other safety-critical domains, work is increasingly characterised by the integration and dissemination of information between humans and technology, across disciplines and over multiple geographical locations.

  6. 4. Optical Investigations of Chiral Liquid Crystals

    Author : Anders Dahlgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antiferroelectric; de Vries theory; ferroelectric; optical activity; chiral; dielectric tensor; unwinding; liquid crystal; helicoidal; selective reflection;

    Abstract : Optical investigations of course involve experimental work, but a theoretical basis is also needed. The first chapter can hopefully can give the non-expert an insight into the science of liquid crystals. Liquid crystals are optically birefringent, and a review of the phenomenon of birefringence follows in chapter 2. READ MORE
