3. 17. Extending the reach of uncertainty quantification in nuclear theory

   Författare :Isak Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The theory of the strong interaction—quantum chromodynamics (QCD)—is unsuited to practical calculations of nuclear observables and approximate models for nuclear interaction potentials are required. In contrast to phenomenological models, chiral effective field theories (χEFTs) of QCD grant a handle on the theoretical uncertainty arising from the truncation of the chiral expansion. LÄS MER

4. 18. On fit uncertainty-reducing interventions in retail supply chains

   Författare :Emmelie Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital product fitting; retail supply chains; experience goods; product recommendation system; product recommender; Fit uncertainty;

   Sammanfattning : Fit uncertainty is used in this doctoral thesis to describe the customer’s experience of uncertainty about the physical fit of a product when shopping for experience goods. Experience goods are products whose attributes are difficult to ascertain without physical examination. LÄS MER

5. 19. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty

   Författare :Dženan Hozić; Carl-Johan Thore; François-Xavier Irisarri; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Optimization; Composite Structures; Topology Optimization; Multi-material Optimization; Material Uncertainty; Robust Optimization; Composite Structure Optimization; Design Optimization; Composite Material;

   Sammanfattning : Composite materials are known to have superior stiffness and strength properties per unit weight compared to metallic materials. These properties and the ability to tailor the mechanical properties of composites is the main motivation for choosing composite materials for structural components. LÄS MER

7. 20. Quantifying pollutant spreading and the risk of water pollution in hydrological catchments : A solute travel time-based scenario approach

   Författare :Klas Persson; Georgia Destouni; Aldo Fiori; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water pollution; catchment; pollution risk; scenario analysis; uncertainty; Physical Geography; naturgeografi;

   Sammanfattning : The research presented in the thesis develops an approach for the estimation and mapping of pollutant spreading in catchments and the associated uncertainty and risk of pollution. The first step in the approach is the quantification and mapping of statistical and geographical distributions of advective solute travel times from pollutant input locations to downstream recipients.
