1. 1. Modelling Sexual Interactions : Sexual behaviour and the spread of sexually transmitted infections on dynamic networks

   Författare :Disa Hansson; Tom Britton; Fredrik Liljeros; KaYin Leung; Janneke Heijne; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Sexually transmitted infections; Egocentric network analysis; Dynamic networks; Sexual behaviour; HIV; Statistical inference; Mathematical Statistics; matematisk statistik;

   Sammanfattning : In this thesis we develop statistical and mathematical models to study different factors of relevance for the spread of sexually transmitted infections (STIs). Two special interest groups for STI interventions are considered: sexually active youths and men who have sex with men (MSM). LÄS MER

3. 2. Modelling anisotropic interactions in colloidal systems

   Författare :Alexei Abrikossov; Fysikalisk kemi; []
   Nyckelord :SIMULATION; Modelling; electrostatic interactions; Colloids; Statistical mechanics; SIMULATION; Modelling; electrostatic interactions; colloid; Statistical mechanics;

   Sammanfattning : There has been an increased interest to design “smart materials” which can self-assemble into complex structures in accordance to external factors such as for example electromagnetic fields. By designing particles with directional interactions one is able to control how particles will interact with each other. LÄS MER

4. 3. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling

   Författare :Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Stefano Beretta; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Extreme Value Statistics; Materialteknik; Engineering Materials;

   Sammanfattning : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. LÄS MER

5. 4. Statistical Modelling and Inference for XENON1T

   Författare :Knut Dundas Morå; Jan Conrad; Alfredo Davide Ferella; Glen Cowan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; direct detection; statistical analysis; fysik; Physics;

   Sammanfattning : A great number of astrophysical observations suggests that of the matter in our universe, only a sixth is made up of known matter. The rest, named dark matter, has not been successfully identified. LÄS MER

7. 5. Statistical Methods for Taxon Classification and Bird Migration Phenology

   Författare :Måns Karlsson; Ola Hössjer; Jonas Knape; Benjamin Bolker; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Classification; quantile regression; phenology; statistical ornithology; L-functionals; set-valued classification; species identification; statistical ecology; multispecies modelling; matematisk statistik; Mathematical Statistics;

   Sammanfattning : The connection between ecology and statistics is deep. Methodological advancement in statistics open up new possibilities to understand the distribution of life on earth, and research questions in ecology cause new statistical methods to be developed. LÄS MER
