1. 1. Improving the guidance, navigation and control design of the KNATTE platform

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Lars Lundström; [2023]
   Keywords : Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

   Abstract : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.

3. 2. Reinforcement Learning for the Optimization of Explicit Runge-Kutta Method Parameters

   University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Mélanie Fournier; [2023]
   Keywords : reinforcement learning; numerical analysis; Runge-Kutta; policy gradient; REINFORCE; Mathematics and Statistics;

   Abstract : Reinforcement learning is one of the three main paradigms in machine learning, which is increasingly used as a method to approach scientific problems. In this thesis, we introduce and use reinforcement learning to find the optimal parameters of a numerical solver. READ MORE

4. 3. Application of Discrete Time High Order Control Barrier Functions for a prototype multi-spacecraft inspection of the ISS

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

   Author : Gregorio Marchesini; [2023]
   Keywords : Space Robotics; Control Barrier Functions; Autonomous systems; Multi-agent systems;

   Abstract : In the past few years, the application of Control Barrier Functions (CBF) and High Order Control Barrier Functions (HOCBF) as a suitable framework to ensure safety for autonomous systems has attracted increasing interest. In particular, autonomous space systems are frequently subject to safety-critical constraints due to the high costs involved in manufacturing and launching. READ MORE

5. 4. Design of a braiding machine : For micro-tubing used in reconfigurable fluidic wearables

   University essay from Uppsala universitet/Industriell teknik

   Author : Andreas Rishaug; Joakim Sandberg; [2022]
   Keywords : braid; braiding; braiding machine; Omnifibre; CNC; computer numerical control; CAM; computer aided manufacturing; manufacturing; milling; turning.;

   Abstract : In this project the objective is to understand how to design a braiding machine capable of automated production of Omnifibre in a research environment. Automated production of Omnifibre is the key issue for the researchers as they want to increase the weaveabilty of the fibers and make it more suitable for use in active textiles. READ MORE

6. 5. Comparing single- and multi-echelon methods for inventory control of spare parts at Volvo

   University essay from Lunds universitet/Produktionsekonomi

   Author : Alexander Larsson; Jakob Bengtsson; [2022]
   Keywords : Single-echelon; Multi-echelon; Spare parts; Inventory Control; Supply Chain Management; Technology and Engineering;

   Abstract : Title: Comparing single- and multi-echelon methods for inventory control of spare parts at Volvo Authors: Jakob Bengtsson & Alexander Larsson Supervisors: Johan Marklund, Lund University | Christian Beckers & Johan Lid- vall, Volvo Background: Spare parts logistics is an area particularly concerned with challenges related to inventory control. The parts are vital to secure the functionality of critical equipment and the management of its supply chain tends to be complex. READ MORE
