  1. 1. LiDAR-Equipped Wireless Sensor Network for Speed Detection on Classification Yards

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

    Author : Isak Olsson; André Lindgren; [2021]
    Keywords : LiDAR; Internet of Things IoT ; Wireless Sensor Networks WSN ; Classification yards; 6LoWPAN; RANSAC; LiDAR; Sakernas internet; Trådlösa sensornätverk; Rangerbangårdar; 6LoWPAN; RANSAC;

    Abstract : Varje dag kopplas tusentals godsvagnar om på de olika rangerbangårdarna i Sverige. För att kunna automatiskt bromsa vagnarna tillräckligt mycket är det nödvändigt att veta deras hastigheter. En teknik som har blivit populär på sistone är Light Detection and Ranging (LiDAR) som använder ljus för att mäta avstånd till objekt. READ MORE

  3. 2. Animation of humanoid characters using reinforcement learning

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

    Author : Erik Lindström; [2019]
    Keywords : Reinforcement Learning; Animation; Procedural Animation; Simulated Swimming;

    Abstract : Procedural animations are still in its infancy, and one of the techniques to create such is using Reinforcement Learning. In this project, swimming animations are created using UnityML version 0.6 with their Reinforcement Learning training agents, using the policy PPO, created by OpenAI. READ MORE

  4. 3. Volumetric reconstruction and representation with applications in radiotherapy planning

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Emma Villemoes; [2018]
    Keywords : Volume reconstruction from contours; shape-based interpolation; adaptively sampled distance field; radiotherapy planning;

    Abstract : Optimization and planning of radiation therapy is performed in a treatment planning system. This includes the definition of target structures to be irradiated and organs at risk to be protected, typically performed by contouring structures slice by slice in the image data. READ MORE

  5. 4. Reflected Stochastic Differential Equations on a Time-Dependent Non-Smooth Domain

    University essay from KTH/Matematisk statistik

    Author : Adam Lindhe; [2018]
    Keywords : Reflected stochastic differential equations; non-smooth; timedependent; Skorokhod problem; Reflekterande stokastiska differentialekvationer; icke-slät; tidsberoende;

    Abstract : In this thesis we prove existence and uniqueness for reflected stochastic differential equation on a specific non-smooth, time-dependent domain. The domain is the intersection of a finite number of smooth domains that are allowed to vary in time. READ MORE

  6. 5. Analysis and implementation of the Smooth Discrete Element Method in AgX

    University essay from Linköpings universitet/Beräkningsmatematik; Linköpings universitet/Tekniska fakulteten

    Author : Thomas Pettersson; [2015]
    Keywords : Granular Dynamics; Discrete Elemant Method;

    Abstract : We encounter granular materials on a daily basis. We walk up a gravel path or we eat our breakfast cereals. When handling granular materials on an industrial scale it is important to do so efficiently, to avoid unnecessary energy losses, wear and tear. READ MORE
