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

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

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

    Sammanfattning : 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. LÄS MER

  3. 22. Effektiv kontroll : En jämförande policyanalys av Sölvesborgs kommuns och Regeringensbrottsförebyggande styrdokument

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kriminologi och polisiärt arbete

    Författare :Viktor Klar; Samuel Falk; [2024]
    Nyckelord :Prevention; brottsförebyggande arbete; problemformulering; kontroll; effektivisering; Sahlins preventionsmodeller; autopoiesis;

    Sammanfattning : The subject of this bachelor thesis in criminology has been local crimeprevention. More specifically the matter of comparing Sölvesborgsmunicipality and the national governments policy regarding local crimeprevention. In 2023 a law regarding municipalities responsibility to institute alocal crime prevention strategy was implemented. LÄS MER

  4. 23. Early-Stage Validation of Autonomous Vehicles in Ambiguous Environments : A Systems-Theoretic Process Analysis (STPA) of an Autonomous Military Defense Industry Vehicle

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Maria Axelsson; [2024]
    Nyckelord :STPA; System Safety; AFRY; Milrem Robotics; Safety Analysis; Autonomous Vehicles; Control Structure; Control Model; NGV; THeMIS; themis; THEMIS;

    Sammanfattning : This report delves into the early developmental phase of an autonomous vehicle designed for defense applications. Navigating diverse terrains, this unmanned ground vehicle (UGV) poses unique challenges, particularly in the absence of clearly defined directives found in typical traffic scenarios. LÄS MER

  5. 24. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Antoni Eritja Olivella; [2024]
    Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER

  7. 25. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Gabriella Zimmerman; [2023-11-07]
    Nyckelord :plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Sammanfattning : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. LÄS MER
