  1. 6. Uncertainties in Neural Networks : A System Identification Approach

    Författare :Magnus Malmström; Fredrik Gustafsson; Isaac Skog; Daniel Axehill; Håkan Hjalmarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; uncertainty; system identification;

    Sammanfattning : In science, technology, and engineering, creating models of the environment to predict future events has always been a key component. The models could be everything from how the friction of a tire depends on the wheels slip  to how a pathogen is spread throughout society. LÄS MER

  3. 7. Energy Reduction of Robot Stations with Uncertainties

    Författare :Mattias Hovgard; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robot station; Stochastic uncertainties; Energy optimization; Industrial robot;

    Sammanfattning : This thesis aims to present a practical approach to reducing the energy use of industrial robot stations. The starting point of this work is different types of robot stations and production systems found in the automotive industry, such as welding stations and human-robot collaborative stations, and the aim is to find and verify methods of reducing the energy use in such systems.

  4. 8. Managing uncertainties in geotechnical parameters : From the perspective of Eurocode 7

    Författare :Anders Prästings; Stefan Larsson; Johan Spross; Rasmus Müller; Kok-Kwang Phoon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eurocode 7; Characteristic value; Partial-factor method; Reliability-based design; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Geotechnical engineering is strongly associated with large uncertainties. Geotechnical site investigations are made only at discrete points and most of a soil volume is never tested. A major issue is therefore how to cost effectively reduce geotechnical uncertainties with respect to structural performance. LÄS MER

  5. 9. Managing Uncertainty in Environmental and Cost Life Cycle Studies of Building Design

    Författare :Peter Ylmen; Jesper Arfvidsson; Kristina Mjörnell; Johanna Berlin; Tomas Ekvall; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building design; life cycle; LCA; LCC; uncertainties; method; Building design; life cycle; LCA; LCC; uncertainties; method;

    Sammanfattning : In order to mitigate global warming and address other pertinent environmental issues, it is important to reduce the environmental impact from the building stock. Emissions can be large for both operational energy consumption and production of materials. LÄS MER

  7. 10. Modelling strategies for thin imperfect interfaces and layers

    Författare :Mathieu Gaborit; Peter Göransson; Olivier Dazel; Lucie Rouleau; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uncertainties; thin layers; numerical methods; simplified models; poroelastic materials; incertitudes; couches fines; méthodes numeriques; modèles simplifiés; matériaux poroélastiques; osäkerheter; tunna lager; numeriska metoder; förenklade modeller; poroelastiska medier; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : The global trend towards quieter environments has been one of the key topics of acoustics research for years. The recent tightening of the regulations on noise exposure as well as the many reports on the impact of noise on human health confirm this situation and stress ever more the need for innovative mitigation strategies.
