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

    Author : Niclas Määttä; Adam Westermark; [2023]
    Keywords : mechatronics; offset-free MPC; MPC; LQR; XT28; forwarder; pendulum arm; forestry; mekatronik; offset-free MPC; MPC; LQR; XT28; skotare; pendelarm; skogsbruk;

    Abstract : A forwarder named XT28 has been developed in joint collaboration between eXtractor AB, Skogforsk AB, KTH, Linköpings Unversity, Sveaskog, and Bosch Rexroth. The forwarder is equipped with six hydraulic active suspension pendulum arms. READ MORE

  3. 2. Reinforcement Learning for Hydrobatic AUVs

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

    Author : Grzegorz Woźniak; [2022]
    Keywords : Deep Reinforcement learning; Deep learning; Optimal control; Hydrobatics; Deep Reinforcement learning; Deep learning; Optimal control; Hydrobatics;

    Abstract : This master thesis focuses on developing a Reinforcement Learning (RL) controller to perform hydrobatic maneuvers on an Autonomous Underwater Vehicle (AUV) successfully. This work also aims to analyze the robustness of the RL controller, as well as provide a comparison between RL algorithms and Proportional Integral Derivative (PID) control. READ MORE

  4. 3. Evaluation of the Scott bond method and testing of out-of-plane properties of paperboard

    University essay from KTH/Hållfasthetslära

    Author : Joel Olsson; [2022]
    Keywords : ;

    Abstract : The through-thickness mechanical behavior of paperboard is fundamental for converting operations and many end-use situations of paper-based products. High quality and uniformity of the through-thickness properties is ensured during paperboard manufacturing by use of on-line and laboratory quality control methods. READ MORE

  5. 4. Development of Test Methodologies and Setups for Thrust Measurements of Cold Gas Micro-thrusters for CubeSats

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Aleksander Kipiela; [2022]
    Keywords : Thrust measurements; cold gas propulsion; micro thrusters; hanging pendulum; CubeSat; Dragkraftsmätning; kallgasframdrivning; mikrodysor; hängande pendel; CubeSat;

    Abstract : Measuring the thrust of cold gas micro-thrusters, due to the small magnitude of the generated force, is a challenging task, and to obtain satisfying quality of results usually careful adjustments of the setup has to be performed. The work presented in this paper aims at improving the quality of such measurements at the GomSpace Sweden company. READ MORE

  6. 5. Applicability of Graph Neural Networks to predict Human variability in Human Body Model Rib Strain Predictions

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Julia Solhed; [2022]
    Keywords : Graph Neural Networks; Human Body Model; SAFER HBM; HBM simulation; Rib strain predictions; Rib fracture risk predictions;

    Abstract : Finite element human body models have in recent years become widely used in the area of vehicle safety evaluations. They make it possible to predict injury risk in specific areas, down to the organ level in the human body. An existing human body model, SAFER HBM includes a rib cage representing an average male.
