    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; Maskinteknik; hydraulik; akustik; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering;

    Sammanfattning : This thesis comprises three different topics within the field of tribology. First, design functions for analyses of slider bearings are developed. Second, a lubricant model applied to elastohydrodynamically lubricated (EHL) line contacts considering wall-slip is presented. LÄS MER

  3. 2. Integrating domain knowledge into deep learning : Increasing model performance through human expertise

    Författare :Niclas Ståhl; Göran Falkman; Alexander Karlsson; Gunnar Mathiason; Jonas Boström; Keith Downing; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; INF301 Data Science; INF301 Data Science; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ;

    Sammanfattning : The research in this thesis is focused on how deep learning models can be designed and implemented to better emulate and integrate the heuristic reasoning process of human experts. Several case studies, within the domains of steel making and drug discovery, are conducted in order to evaluate the performance of these models, in comparison to models that do not consider human expert knowledge from the targeted domain.

  4. 3. Designing for Interactional Empowerment

    Författare :Anna Ståhl; Kristina Höök; Jonas Löwgren; Erik Stolterman; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Human-computer Interaction; Människa-datorinteraktion;

    Sammanfattning : This thesis further defines how to reach Interactional Empowerment through design for users. Interactional Empowerment is an interaction design program within the general area of affective interaction, focusing on the users’ abil­ity to reflect, express themselves and engage in profound meaning-making.

  5. 4. Elastohydrodynamic Lubrication of Cam and Roller Follower

    Författare :Mohammad Shirzadegan; Jonas Ståhl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Modelling and simulation of friction is a research issue that still requires an extensive amount of input from the scientific community. In a lubricated system, the dissipation of energy is connected to the direct contact between the surfaces, or more precisely the tribofilms, as well as of the shearing of the lubricant film. LÄS MER
