  1. 11. Goal-Oriented Adaptive Finite Element Analysis in Computational Material Mechanics

    Författare :Fredrik Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; visco-plasticity; a posteriori error estimation; thermo-elasticity; mesh refinement; adaptivity; FEM; elasticity;

    Sammanfattning : This thesis is concerned with error control in computational material mechanics. A posteriori error estimation and adaptivity for finite element discretizations is investigated. Based on the technique of solving a dual problem, it is possible to control the accuracy of arbitrary quantities. LÄS MER

  4. 13. Iron or Copper? - Method Development and Mechanistic Studies on Cross-Coupling Reactions

    Författare :Per-Fredrik Larsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Iron; Copper; Transition metal; Cross-coupling; Reaction mechanism; Kinetic investigation; Hammett study; Sustainable catalysis; Trace-metal; Mass-transfer; Ligand development; Ligand scope;

    Sammanfattning : The area of catalysis has had an immeasurable impact on modern society. This has been acknowledged through several Nobel prizes during the 20th century ranging from Haber (1918) for the synthesis of ammonia to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki (2010) for palladium-catalyzed cross-coupling reactions. LÄS MER

  5. 14. Window Layer Structures for Chalcopyrite Thin-Film Solar Cells

    Författare :Fredrik Larsson; Tobias Törndahl; Jan Keller; Marika Edoff; Daniel Lincot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CIGS; atomic layer deposition; ALD; thin-film technology; window layer structures; buffer layers; front contacts; metal oxides; ternary compounds; CIGS; tunnfilmssolceller; ALD; tunnfilmsteknik; fönsterlager; buffertlager; framkontakter; metalloxider; ternära föreningar; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : This thesis aims to contribute to the development of improved window layer structures for chalcopyrite thin-film solar cells, with an emphasis on the buffer layer, to assist future reductions of the levelized cost of energy. This is realized by exploring the potential of existing materials and deposition processes, as well as developing new buffer layer processes based on atomic layer deposition (ALD). LÄS MER

  7. 15. Rupture and Repair in the Working Alliance : Relation to Psychotherapy Outcome and Within-Session Interaction

    Författare :Mattias Holmqvist Larsson; Gerhard Andersson; Fredrik Falkenström; Rolf Holmqvist; Jonas Ramnerö; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Rupture and repair; working alliance; interpersonal interaction; psychotherapy outcome; Alliansbrott och reparation; arbetsallians; interpersonell interaktion; utfall av psykologisk behandling;

    Sammanfattning : Ruptures and repairs are processes related to shifts in the collaborative relationship Cthe working allianceJ between patient and therapist in psychotherapy. Ta study ruptures and repairs is one way ta disentangle mechanisms that might underlie the association between the working alliance and psychotherapy outcome. LÄS MER
