1. 1. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

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

   Author : Federico Gatti; [2024]
   Keywords : Robotics; Space Engineering; Docking Maneuvers; Floating Platforms; Nonlinear MPC; MPC; Barrier function; PWM;

   Abstract : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. READ MORE

3. 2. Quantum Optical Description of High-order Harmonic Generation

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isabel Moreno; [2024]
   Keywords : Physics and Astronomy;

   Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

4. 3. Mellanrum: Towards an Entangled Audiovisual Practice

   University essay from Göteborgs universitet/Högskolan för scen och musik

   Author : Julius Norrbom; [2023-01-23]
   Keywords : audiovisual; generative art; generative music; modular synthesizer; electronic music; systems; networks;

   Abstract : This artistic research project is a document of an entangled audiovisual practice in progress. With a generative approach and thinking in systems applied to modular synthesizers and procedural computer graphics the aim is to blur the line between the process of generating sounding material and the process of generating visual material.

5. 4. Wavelength-dependent limb darkeningin the analysis oftransit spectroscopy of exoplanets

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Alberto García Ribas; [2023]
   Keywords : ;

   Abstract : Limb darkening, an optical effect characteristic of stars, where the limb (edge) seemsto be darker than the centre of the stellar body; plays an important role in our under-standing of exoplanetary transits, as it is fundamental for developing light curve modelsthat can help to undercover extrasolar companions. To recover atmospheric featuresfrom exoplanets, a principal component analysis method is typically used. READ MORE

6. 5. Predictive Controllers for Load Transportation in Microgravity Environments

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

   Author : Sujet Phodapol; [2023]
   Keywords : Model Predictive Control; Decentralized control; Multi-robot systems; Space technology; Modell-prediktiv reglering; Decentraliserad reglering; Multirobotsystem; Rymdteknologi;

   Abstract : Space activities have been increasing dramatically in the past decades. As a result, the number of space debris has also increased significantly. Therefore, it is necessary to clean up and remove them to prevent a collision between space debris and spacecraft. READ MORE
