  1. 21. Theoretical Actinide Chemistry – Methods and Models

    Författare :Pernilla Wåhlin; Ulf Wahlgren; Luis Seijo; Stockholms universitet; []
    Nyckelord :Actinide; Quantum chemistry; Wave function; Density functional theory; Solvent models; Water exchange; Molecular configurations; Multi-reference density functional method; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The chemistry of actinides in aqueous solution is important, and it is essential to build adequate conceptual models and develop methods applicable for actinide systems. The complex electronic structure makes benchmarking necessary. LÄS MER

  3. 22. Breathtaking Greenhouse Parastructures : a supplement to the Arcades Project from a Caribbean Perspective [and a call for a careful practice of epistemológica]

    Författare :Luis Berríos-Negrón; Leif Dahlberg; Håkan Nilsson; Florian Dombois; Bonaventure Soh Bejeng Ndikung; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; greenhouse; colonial memory; phenomenotechnologies; global warming; sculpture; installation art; Art; Technology and Design; Konst; teknik och design;

    Sammanfattning : Breathtaking Greenhouse Parastructures is a doctoral work that supplements the unfinished modern opus The Arcades Project [in German Das Passagen-Werk (Mit Bindestrich und Werk mit Capital W) ]. The supplement takes the form of a sculptural, historical, and technological deposition of ‘greenhouse’ that presently oscillates between a past-background and future-foreground to Walter Benjamin's ‘theatrical’ handling of the Parisian arcades.

  4. 23. Wheeled Operads in Algebra, Geometry, and Quantization

    Författare :Johan Granåker; Sergei A. Merkulov; Andrey Lazarev; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operads; deformation theory; homotopy algebra; deformation quantization; MATHEMATICS; MATEMATIK; Mathematics; matematik;

    Sammanfattning : The theory of generalized operads, the foundational conceptual framework of this thesis, has become a universal language, relating various areas such as algebraic topology, derived categories of algebras, deformation theory, differential geometry and the mathematical theory of quantization.The thesis consists of a preliminary chapter followed by four main chapters.

  5. 24. Fast Particle Driven Instabilities in Tokamak Plasmas

    Författare :Robert Nyqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The burning plasmas of the next generation tokamak fusion experiment ITERwill contain signicant populations of highly energetic ions. Both fusion gener-ated alpha particles and fast ions accelerated by auxiliary heating schemes arecapable of exciting instabilities in the Alfven frequency range, which may inturn cause redistribution of energetic particles and lead to deleterious eventssuch as e.

  7. 25. Creep Behaviour of Titanium Aluminides and its Relation to Phase Distributions and Dislocation Structures

    Författare :Dennis Lundström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma-TiAl; twinning; fatigue; dislocations; microstructure; thermal transport properties; creep;

    Sammanfattning : The need for more efficient gas turbines with lowered fuel consumption and thereby lowered emission has recently lead to increased interest in low-density, .gamma.-based TiAl intermetallic alloys as a replacement of e.g. LÄS MER
