  1. 1. Praktisk modellering av vitvatten i den turbulenta vaken för jämförelse av marina propulsorer

    Master-uppsats, KTH/Marina system

    Författare :Felix Brodin; [2020]
    Nyckelord :;

    Sammanfattning : En semi-empirisk modell som beskriver vitvattets sönderfall i den turbulenta vaken har härletts utifrån optiska studier av Stridsbåt 90H och Buster Magnum. Bakgrunden är ett ökat hot från rymdburna system mot den svenska Marinen. Fokus har varit Amfibiekårens båtpark. LÄS MER

  3. 2. A Gimbal Stabilizer : Self-stabilizing platform for holding objects horizontally stable

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maksims Svjatoha; Behnam Yosef Nezhad Arya; [2019]
    Nyckelord :mechatronics; stabilizer; self-stabilizing; feedback control; PID; Arduino; inertial stabilization.; mekatronik; stabilisering; plattform; självstabiliserande; återkoppling; reglerteknik; PID; Arduino.;

    Sammanfattning : This bachelor thesis is about the design and construction of a self-stabilizing platform. The purpose of this system is to balance objects placed upon the platform by keeping the platform level regardless of how the mechanism itself is rotated. Its uses include stabilization of sensors, cameras and vehicle cockpits. LÄS MER

  4. 3. Reviewing environmental rebound effects from peer-to-peer boat sharing in Finland

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jon Warmington-Lundström; [2019]
    Nyckelord :Sustainable Development; Circular Economy; Sharing Economy; Peer-to-Peer Shared Access; Environmental Rebound Effect.;

    Sammanfattning : The world crucially needs to reduce the level of emissions being released in the environment in order to combat climate change. With the global population increasing and economies continuing to grow, the circular economy has been heralded by many as the potential solution to economic prosperity whilst also reducing primary resource use and emissions.

  5. 4. Gimbal stabilizer for cockpit bases of terrain vehicle or combat boat : A proof of concept

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Joel Larsson; [2018]
    Nyckelord :gimbal; inertially stabilized platform;

    Sammanfattning : The purpose of this project was to construct a 2-axis stabilized model platform, as a proof of concept, intended to use for a cockpit base of a terrain vehicle or a combat boat. The stabilization of the platform in the roll and pitch axes is realized using a feedback control system that contains a proportional-integral-derivative (PID) controller, two DC motors driving the roll and pitch movements, and a 6-axis inertial measurement unit (IMU) measuring the roll and pitch angles.

  7. 5. Militär nytta i Adenviken : En undersökning av de system som används för piratbekämpning

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Johan Törnblom; [2018]
    Nyckelord :Military utility; Light utility helicopter; Medium utility helicopter; Combat boat; Reconnaissance aircraft; Drone; Gulf of Aden; Counterpiracy; Militär nytta; Lätt helikopter; Medeltung helikopter; Stridsbåt; Spaningsflygplan; Drönare; Adenviken; Piratbekämpning;

    Sammanfattning : This thesis studies the counterpiracy in the Gulf of Aden. Pirates has made the international community deploy military forces to police the Gulf of Aden. However most of the systems usedare not designed for counterpiracy. Many are remnants from the cold war. LÄS MER
