  1. 1. Att mista sitt roder. Hur avslag på och indrag av sjukpenning kan påverka människor med utmattningssyndrom.

    Magister-uppsats, Göteborgs universitet/Institutionen för socialt arbete

    Författare :Rebecka Håkman; [2022-06-30]
    Nyckelord :utmattningssyndrom; sjukpenning; avslag; indrag; Försäkringskassan;

    Sammanfattning : Syftet med denna studie var att undersöka hur personer med utmattningssyndrom kan påverkas av avslag på och indrag av sjukpenning. Forskningsfrågan var: Hur kan personer med utmattningssyndrom påverkas psykiskt, socialt, fysiskt och ekonomiskt av avslag på och indrag av sjukpenning? Kvalitativ metod användes och datainsamlingen gjordes med semistrukturerade intervjuer. LÄS MER

  3. 2. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Sigurlaug Rún Jónsdóttir; [2022]
    Nyckelord :Nonlinear optimization; nonlinear optimal control; numerical optimal control; real-time solution; optimal braking; receding horizon; modeling; ship model; propeller forces; rudder forces; direct multiple shooting method; discretization;

    Sammanfattning : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. LÄS MER

  4. 3. Risk Contours for RemoteOperations Centres forMaritime AutonomousSurface Ships

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

    Författare :Andreas Baldhagen; Jonas Lindström; [2022]
    Nyckelord :Monitoring of autonomous vehicles; Autonomous vessels; Remote operations centers; Maritime autonomous surface ships; Land­based monitoring; Risk contours.; Risk­konturer; Fjärroperationscentraler; Marina autonoma ytfartyg; Övervakning av autonoma fordon; Autonoma fartyg; Landbaserad övervakning.;

    Sammanfattning : To monitor and control maritime autonomous surface ships in a land­based remote operations centre leads to several advantages compared to today when a whole crew is needed on board. For example, less humans would be required to control the same amount of ships, less personnel would be required to live or stay on the ship for a longtime and risk being injured or die in accidents or storms.

  5. 4. Primary flight control design for a 4-seat electric aircraft

    Master-uppsats, KTH/Flygdynamik

    Författare :Cyril Lachaume; [2021]
    Nyckelord :Flight control; Kinematics; Aircraft; Mechanics; Hybrid electric; Flygkontroll; kinematik; flygplan; mekanik; hybridelektrisk;

    Sammanfattning : This thesis work is part of a design process which aims to develop a four-seathybrid-electric aircraft at Smartflyer (Grenchen, Switzerland). In that scope,various mechanisms of the plane had to be developed, including the systemactuating the control surfaces. LÄS MER

  7. 5. Parametric Adjoint Optimization of a Twisted Rudder

    Master-uppsats, KTH/Marina system

    Författare :Andreas Hörberg; [2020]
    Nyckelord :Maritime; CFD; Optimization; Adjoint method; Twisted rudder; Sjofart; CFD; Optimering; Adjointmetoden; Tvistat roder;

    Sammanfattning : Optimization methods are commonly used to develop new products and are also an importantstep in more incremental design improvements. In the maritime industry, these methodsare often used to create more ecient vessels and to ful ll the environmental requirementsimposed by the IMO. In recent years, the adjoint method have been used more frequently. LÄS MER
