  1. 1. Data-Driven Adaptive Control of Unmanned Surface Vehicles Using Learning-Based Model Predictive Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Markus Svedberg; [2023]
    Keywords : Technology and Engineering;

    Abstract : In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. READ MORE

  3. 2. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels

    University essay from KTH/Betongbyggnad

    Author : Elin Brodd; Lina Östlund; [2022]
    Keywords : Shotcrete; Global Warming Potential; Environmental Product Declaration; Tunnel construction; Fibre reinforcement; Compressive strength; Residual strength; GGBS; Sprutbetong; Klimatpåverkan; Miljövarudeklaration; Tunnelbyggande; Fiberarmering; Tryckhållfasthet; Residualhållfasthet; Granulerad Masugnsslagg;

    Abstract : The dominating support method for hard rock tunnels today is use of fibre reinforced shotcrete in combination with rock bolts. The fibre reinforced shotcrete secures smaller blocks, while rock bolts are used to support larger blocks in the rock. Application of shotcrete is done by spraying against the rock surface using compressed air. READ MORE

  4. 3. Effects of Temperature and Moisture Content on Young’s Modulus in Glass Fiber Reinforced Polyamide

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Joel Sandberg; Samuel Sjölin; [2022]
    Keywords : Polyamide; nylon 66; PA66GF25; glassfiber reinforced polyamide; Young’s modulus; Polyamid; nylon 66; PA66GF25; glasfiberförstärkt polyamid; Youngs modul.;

    Abstract : This thesis was made in cooperation with Roxtec. Roxtec specialises in cable sealingsolutions and are world leading in their area. In many of Roxtec’s products steel isused in the frame holding the sealing rubber. To lower Roxtec’s environmental foot-print plastic would be used instead in the frames if possible, more specific polyamide6. READ MORE

  5. 4. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    University essay from KTH/Lättkonstruktioner

    Author : Luis Alfonso Penela Guerrero; [2022]
    Keywords : Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Abstract : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. READ MORE

  6. 5. Labyrinth Navigation Using Reinforcement Learning with a High Fidelity Simulation Environment

    University essay from Linköpings universitet/Reglerteknik

    Author : Olle Eriksson; Axel Malmberg; [2022]
    Keywords : ;

    Abstract : This is a master thesis on the subject of navigation and control using reinforcementlearning, more specifically discrete Q-learning. The Q-learning algorithmis used to develop a steer policy from training inside of a simulation environment.The problem is to navigate a steel ball through a maze made from walls and holes. READ MORE
