  1. 1. Identifying Fundamental Characteristics of Shock Nonstationarity using MMS Measurements : Identifying and Distinguishing Non-stationary Behaviour Through the Magnetic Field Gradient in Quasi-perpendicular Shocks

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

    Author : Hannah Wik; [2023]
    Keywords : Space; Space Plasma Physics; Collisionless Shocks; MMS; Non-stationarity; Shock Reformation; Rippling; Bow Shock; Solar Wind; Rymd; Rymdfysik; Kollisionsfria chocker; MMS; Icke-stationär; Reformation; Bogchock; Solvind;

    Abstract : Collisionless shocks are widespread phenomena in the universe, and understanding the mechanisms behind their energy dissipation, with a rare number of collisions between particles, remains a significant unresolved question. The Earth’s bow shock provides an excellent opportunity to study this phenomena in situ. READ MORE

  3. 2. Tackling Non-Stationarity in Reinforcement Learning via Latent Representation : An application to Intraday Foreign Exchange Trading

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

    Author : Adriano Mundo; [2023]
    Keywords : Reinforcement Learning; Latent Representation; VAE; Non-Stationary; FQI; FX Trading; Förstärkningsinlärning; Latent representation; VAE; Icke-stationär; FQI; FX handel;

    Abstract : Reinforcement Learning has applications in various domains, but the typical assumption is of a stationary process. Hence, when this hypothesis does not hold, performance may be sub-optimal. READ MORE

  4. 3. Causal discovery in conditional stationary time-series data : Towards causal discovery in videos

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

    Author : Carles Balsells Rodas; [2021]
    Keywords : Causality; Causal discovery; Neural networks; Graph neural network; Time series; Non-stationary; Orsakssamband; Kausal upptäckt; Neurala nätverk; Diagram Neurala nätverk; Tidsföljder; Icke-stationär;

    Abstract : Performing causal reasoning in a scene is an inherent mechanism in human cognition; however, the majority of approaches in the causality literature aiming for this task still consider constrained scenarios, such as simple physical systems or stationary time-series data. In this work we aim for causal discovery in videos concerning realistic scenarios. READ MORE

  5. 4. A tracking framework for a dynamic non- stationary environment

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

    Author : Sebastian Ståhl; [2020]
    Keywords : Object detection; tracking; geolocation; UAV; Yolov3; KCF.; Objektdetektering; spårning; lokalisering; drönare; Yolov3; KCF.;

    Abstract : As the use of unmanned aerial vehicles (UAVs) increases in popularity across the globe, their fields of application are constantly growing. This thesis researches the possibility of using a UAV to detect, track, and geolocate a target in a dynamic nonstationary environment as the seas. READ MORE

  6. 5. Establishment of an open 3D steam turbine flutter test case

    University essay from KTH/Energiteknik

    Author : Di Qi; [2016]
    Keywords : ;

    Abstract : An open three-dimensional (3D) flutter test case for steam turbines is presented. Unlike previous research on turbine flutter, the geometry is an open resource and is from a test case originally presented by Durham University. READ MORE
