  1. 11. Uncertainties in modeling groundwater contamination

    Författare :Bruno Mendes; Christian Ekberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

    Sammanfattning : The scientific problem of nuclear waste disposal suffers from stronguncertainties arising both from its object (the system being studied being unknown) and also from its ambitious objectives (prediction of future events and their consequences). This work focuses on identifying, structuring and quantifying the main uncertainties involved in this field. LÄS MER

  3. 12. Robust design : Accounting for uncertainties in engineering

    Författare :David Lönn; Larsgunnar Nilsson; Niclas Strömberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  4. 13. The Uncertainty-Embedded Innovation Process : A study of how uncertainty emerges in the innovation process and of how firms address that to create novelty

    Författare :Sabrina Luthfa Karim; Gabriel Baffour Awuah; Mikael Hilmersson; Klaus Solberg Søilen; Anna Öhrwall Rönnbäck; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation process; Uncertainties; Compromised and uncompromised actions; Actors; Resources; Activities; Activity links; Activity void;

    Sammanfattning : Despite much discussion in the literature of uncertainties in relation to the innovation process, there is little knowledge of how they emerge in this process. This thesis accordingly aims to understand how uncertainty emerges in the innovation process and how firms address that uncertainty to create novelty from the process. LÄS MER

  5. 14. Hygrothermal Simulations of Buildings Concerning Uncertainties of the Future Climate

    Författare :Vahid Nik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould growth; climate change; climate uncertainties; hygrothermal simulation; energy demand;

    Sammanfattning : Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. LÄS MER

  7. 15. Assessing reactive nitrogen flows in European agricultural systems

    Författare :Rasmus Einarsson; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; food; nitrogen indicator; nitrogen budget; nitrogen; agriculture; nitrogen footprint; uncertainties;

    Sammanfattning : In most ecosystems, nitrogen is a scarce and growth-limiting nutrient. Natural and anthropogenic processes convert unreactive atmospheric dinitrogen (N2) into reactive, bioavailable, nitrogen. LÄS MER
