  1. 1. Light scattering and absorption in pigmented coatings : Theory and experiments

    Författare :William E. Vargas; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Radiative transfer models are used to describe optical properties of polymericthick films containing spherical inhomogeneities with sizes comparable to thewavelength of the incident radiation. From Lorenz-Mie theory various parametersrelated to elastic light scattering and absorption by single particles are calculated, i.e. LÄS MER

  3. 2. Extensions in Flux : An Essay on Vagueness and Context Sensitivity

    Författare :Jonas Åkerman; Peter Pagin; Diana Raffman; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; vagueness; context sensitivity; contextualism; weak tolerance; sorites paradox; forced march; equivocation; indexicals; Fara; Raffman; Shapiro; Soames; Theoretical philosophy; Teoretisk filosofi; Theoretical Philosophy; teoretisk filosofi;

    Sammanfattning : The extensions of vague predicates like ‘is bald’, ‘is tall’, and ‘is a heap’ apparently lack sharp boundaries, and this makes such predicates susceptible to soritical reasoning, i.e. reasoning that leads to some version of the notorious sorites paradox. LÄS MER

  4. 3. Pierced, Wrapped and Torn : Aspects of String Theory Compactifications

    Författare :Magdalena Larfors; Ulf Danielsson; Gary Shiu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical physics; Matematisk fysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : An outstanding problem in physics is to find a unified framework for quantum mechanics and general relativity. This is required for a better understanding of black holes and the early cosmology of the universe. String theory provides such a unification. In this thesis, we study aspects of compactifications of type IIB string theory. LÄS MER

  7. 5. Supersymmetric Geometries in Type IIA Supergravity

    Författare :Christian von Schultz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flux compactifications; Supergravity; Supersymmetry; Superstring vacua;

    Sammanfattning : Supergravity theory is any supersymmetric theory with a local supersymmetry parameter. This thesis undertakes the study of type IIA supergravity, a supergravity theory in ten dimensions associated with type IIA string theory. LÄS MER
