  1. 1. Network Drone Control using Deep Reinforcement Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alex Hermansson Grobgeld; [2020]
    Keywords : ;

    Abstract : In this work, a reinforcement learning approach is adopted to control a drone in a cellular network. The goal is to find paths between arbitrary locations such that low radio quality areas, defined with respect to signal-to-interference-plus-noise-ratio, are avoided with the cost of longer flight paths.

  2. 2. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annica Gustafsson; [2019]
    Keywords : Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

    Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE

    Abstract : Today, the main research field for the automotive industry is to find solutions for active safety. In order to perceive the surrounding environment, tracking nearby traffic objects plays an important role. READ MORE

  4. 4. 5G Positioning using Machine Learning

    University essay from Linköpings universitet/Reglerteknik

    Author : Magnus Malmström; [2018]
    Keywords : 5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

    Abstract : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.

  5. 5. On Shock Propagation in Financial Networks

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Isabelle Rosenberg; Viktor Svensson; [2018]
    Keywords : Technology and Engineering;

    Abstract : This thesis develops a simplified financial network model for an interbank lending system which is then analyzed in terms of contagion when exposed to external liquidity shocks. The aim is to understand how individual institutions and the network structure affect the shock propagation and finding factors that increase respectively decrease the systemic risk of the network.
