1. 1. Water and Heat Transport in Road Structures : Development of Mechanistic Models

   Författare :Klas Hansson; Lars-Christer Lundin; Kurt Roth; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Water flow; Heat flow; Unsaturated flow; Freeze-thaw; Numerical models; Uncertainty analysis; Sensitivity analysis; Roads; Overland flow; Flow patterns; TDR; Water content reflectometer; Calibration; Fractures; Hydrologi; Hydrology; Hydrologi;

   Sammanfattning : The coupled transport of water and heat, involving freezing and thawing, in the road structure and its immediate environment is important to consider for optimal design and maintenance of roads and when assessing solute transport, of e.g. de-icing salt, from roads. LÄS MER

3. 2. CALIBRATION OF CHROMATOGRAPHY MODELS

   Författare :Patrik Persson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

   Sammanfattning : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. LÄS MER

4. 3. Calibration of Probabilistic Predictive Models

   Författare :David Widmann; Fredrik Lindsten; Meelis Kull; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; Matematisk statistik;

   Sammanfattning : Predicting unknown and unobserved events is a common task in many domains. Mathematically, the uncertainties arising in such prediction tasks can be described by probabilistic predictive models. Ideally, the model estimates of these uncertainties allow us to distinguish between uncertain and trustworthy predictions. LÄS MER

5. 4. Probabilistic Calibration of Building Energy Models : For Scalable and Detailed Energy Performance Assessment of District-Heated Multifamily Buildings

   Författare :Lukas Lundström; Erik Dahlquist; Angela Sasic; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : There is a global need to reduce energy consumption and integrate a larger share of renewable energy production while meeting expectations for human well-being and economic growth. Buildings have a key role to play in this transition to more sustainable cities and communities. LÄS MER

7. 5. Conceptual runoff models - fiction or representation of reality?

   Författare :Jan Seibert; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Validation; conceptual runoff models; calibration; uncertainty; TOPMODEL; HBVmodel; groundwater levels; spatial distribution; topography; Geovetenskap; Earth sciences; Geovetenskap; Hydrology; hydrologi;

   Sammanfattning : Available observations are often not sufficient as a basis for decision making in water management. Conceptual runoff models are frequently used as tools for a wide range of tasks to compensate the lack of measurements, e.g., to extend runoff series, compute design floods and predict the leakage of nutrients or the effects of a climatic change.
