1. 1. An Introduction to Hitchin Systems

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

   Author : Manuel Neumayer; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : This thesis aims to introduce the tools that are needed to understand — and historically led to the inception of — Hitchin systems. We lay out a basic theory of Hamiltonian systems on symplectic manifolds, and prove the Liouville-Arnold theorem, which states that integrable Hamiltonian systems admit coordinates in which their solution is basically linear.

3. 2. Deanonymizing Onion Services byIntroducing Packet Delay

   University essay from Blekinge Tekniska Högskola

   Author : Johannes Ödén; [2022]
   Keywords : ;

   Abstract : Background. Onion services facilitate two-way communication over the Tor net-work without letting either party know the other address or location. Many different techniques to break that anonymizing have come forth, but most of them have only been on paper. Some have been tested but then only on a separate network and not on the live Tor network. READ MORE

4. 3. Autonomous Landing of a UAV ona Moving UGV Platform using Cooperative MPC

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

   Author : Luca Garegnani; [2021]
   Keywords : Cooperative control; Model Predictive Control; Rendezvous problem; Autonomous landing; Unmanned Aerial Vehicle; Kooperativ reglering; Modellprediktiv reglerteknik; Rendezvous problem; Autonom landning; Obemannad luftfarkost;

   Abstract : Cooperative control of autonomous multi-agent systems is a research areawhich is getting significant attention in recent years. Multi-agent systemsallow for a broad spectrum of applications and cooperation can increasetheir flexibility, efficiency and robustness to changes in external constraintsand disturbances. READ MORE

5. 4. Methods to operate and evaluate the performance of a cold-gas CubeSat propulsion system on a magnetically stabilised satellite

   University essay from KTH/Rymdteknik

   Author : Victor Alberto Gonzalez Marin; [2020]
   Keywords : Propulsion system; CubeSat; Performance; Operating procedure; Mission experiment; Framdrivningssystem; CubeSat; Prestanda; Driftsrutin; Driftprov;

   Abstract : Propulsion systems allow satellites to perform many functionalities in space, such as orbital station keeping, reentry control, attitude control, orbital transferring, rendezvous operation, and even more thrilling, interplanetary travel. Indeed, propulsion systems in satellites have fostered a new favourable era of space exploration and application, therefore, detailed processes to operate propulsion systems need to be developed so that space missions, carrying this valuable system, are completed successfully.

6. 5. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit

   University essay from KTH/Rymdteknik

   Author : Hasan Basaran; [2020]
   Keywords : Aerospace; Chief; Control; Deputy; Feedback Linearization; Follower; Formation Flight; Fuel Consumption; Guidance; Leader; Model Predictive Control; Relative Orbit; Rendezvous; Sliding Mode.;

   Abstract : Formation flying of satellites describes a mission in which a set of satellites arrange their position with respect to one another. In this paper, satellite formation flying guidance and control algorithms are investigated in terms of required velocity increment Delta-v, and tracking error for a Chief/Deputy satellite system.
