  1. 1. Deep Reinforcement Learning for Adaptive Human Robotic Collaboration

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Johan Fredin Haslum; [2019]
    Nyckelord :;

    Sammanfattning : Robots are expected to become an increasingly common part of most humans everyday lives. As the number of robots increase, so will also the number of human-robot interactions. For these interactions to be valuable and intuitive, new advanced robotic control policies will be necessary. LÄS MER

  3. 2. Detecting Trends on Twitter : The Effect of Unsupervised Pre-Training

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Sandra Bäckström; Johan Fredin Haslum; [2016]
    Nyckelord :;

    Sammanfattning : Unsupervised pre-training has recently emerged as a method for initializing super- vised machine learning methods. Foremost it has been applied to artificial neural networks (ANN). Previous work has found unsupervised pre-training to increase accuracy and be an effective method of initialization for ANNs[2].

  4. 3. Minimiarmering enligt Eurokod : En jämförelse mellan EKS 9 och EKS 10

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik

    Författare :Johan Hjälte; Johan Fredin; [2016]
    Nyckelord :Sprickbreddsbegränsning; EKS; Eurokod; Minimiarmering;

    Sammanfattning : This thesis deals with the minimum reinforcement inconcrete structures and the changes made in theregulations on this with the introduction of EKS 10. EKS10, which was introduced January 1, 2016, is theswedish national annex to the common Eurocode. LÄS MER

  5. 4. Speaker that uses the non-linearity in air to create sound

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Johan Fredin; [2005]
    Nyckelord :Parametric loudspeaker; Difference frequency generation; Biharmonic boundary condition; Nonlinear acoustics;

    Sammanfattning : The aim of this work was to investigate theoretically and experimentally the fact that it is possible to create sound by using the nonlinearity in air. A speaker was built verifying the theory that if at least two high frequencies at high amplitude is propagating through a nonlinear medium, for example air, the difference frequency of these two is created in mid air.
