1. 1. Non-Standard Crystallography : Examples in 3- and 3+1 Dimensional Space

   Författare :Jeppe Christensen; Sven Lidin; An-Pang Tsai; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modulation; Crystallography; intermetallic; materials; Chemistry; Kemi; strukturkemi; Structural Chemistry;

   Sammanfattning : Crystallography today is by many seen as merely a tool for determining the structure of a material on the atomic level. It is expected that whatever comes out of the tool is the indisputable truth, a fact. This thesis is based on five publications illustrating that this is very far from the real world of materials research. LÄS MER

3. 2. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations

   Författare :Jessica Franzén; Daniel Thorburn; Jukka Corander; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; Statistics; Statistik; Statistics; statistik;

   Sammanfattning : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. LÄS MER

4. 3. Theoretical and Phenomenological Studies of Neutrino Physics

   Författare :Mattias Blennow; Tommy Ohlsson; Eligio Lisi; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutrino mass; neutrino mixing; neutrino oscillations; matter effects; non-standard effects; the day-night effect; solar neutrinos; accelerator neutrinos; exact solutions; three-flavor effects; large density; neutrino decay; neutrino decoherence; neutrino absorption; non-standard neutrino interactions; seesaw mechanism; stability criteria; leptogenesis; Physics; Fysik;

   Sammanfattning : This thesis is devoted to the theory and phenomenology of neutrino physics. While the standard model of particle physics has been extremely successful, it fails to account for massive neutrinos, which are necessary to describe the observations of neutrino oscillations made by several different experiments.

5. 4. Delving in the Dark : Searching for Signatures of Non-Standard Physics in Cosmological and Astrophysical Observables

   Författare :Janina J. Renk; Joakim Edsjö; Pat Scott; Felix Kahlhöfer; David F. Mota; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmology; gravitation; Galileon; dark energy; dark matter; cosmic superstrings; neutrino mass; parameter inference; teoretisk fysik; Theoretical Physics;

   Sammanfattning : The dark sectors of our Universe, dark matter and dark energy, together constitute about 96 % of the total energy content of the Universe. To date, we only have observational evidence for their existence. LÄS MER

7. 5. Syntactic Variation in the Swedish of Adolescents in Multilingual Urban Settings : Subject-verb Order in Declaratives, Questions and Subordinate Clauses

   Författare :Natalia Ganuza; Kari Fraurud; Paul Kerswill; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; syntactic variation; subject-verb inversion; non-inversion; language use in multilingual urban settings; multilingual youths; standard non-standard; Swedish; SLA; Bilingualism; Tvåspråkighet; tvåspråkighetsforskning; Bilingualism Research;

   Sammanfattning : This thesis investigates the use of word order variation, in particular the variable use of subject-verb inversion and non-inversion in main declarative clauses, among adolescents in contemporary multilingual settings in Sweden. The use of non-inversion in contexts that in standard Swedish require inversion is sometimes claimed to be characteristic of varieties of Swedish spoken among adolescents in multilingual urban areas.
