  1. 16. Automatic Tuning of Motion Control System for an Autonomous Underwater Vehicle

    University essay from Linköpings universitet/Reglerteknik

    Author : Markus Andersson; [2019]
    Keywords : Automatic Control; Automatic Tuning; Control; Motion Control; Modelling; System Identification; Online Identification; Underwater Vehicle; Autonomous Underwater Vehicle; AUV; SMaRC; Maribot LoLo; Differential drive;

    Abstract : The interest for marine research and exploration has increased rapidly during the past decades and autonomous underwater vehicles (AUV) have been found useful in an increased amount of applications. The demand for versatile platform AUVs, able to perform a wide range of tasks, has become apparent. READ MORE

  3. 17. Optimal configuration of the mechanical structure and flap actuator for hydrofoils

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Stanislav Minko; [2019]
    Keywords : ;

    Abstract : Hydrofoil vessels are becoming more popular and driving marine development forward. Since the water friction is greatly reduced, they allow achieving higher speeds and electrification of the boats. FoilCart is a full electric active controlled hydrofoil boat designed as a research project at KTH. READ MORE

  4. 18. Analysis of the intake grill for marine jet propulsion

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marcus Söderberg Jansson; [2019]
    Keywords : Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

    Abstract : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. READ MORE

  5. 19. The Importance of Trait Mediated Indirect Interactions in Marine Ecosystems

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Carlos Valbuena-Gonzalo; [2019]
    Keywords : TMII; BMII; behaviour; predation; non-comsuptive effect;

    Abstract : The importance of Trait Mediated Indirect Interactions (TMII) is increasingly being recognized. TMII are interactions between two species via a change in trait (behavioural, morphological, but not numerical) over a third one, which together cause ecological dynamics. READ MORE

  6. 20. Efficient seakeeping performance predictions with CFD

    University essay from KTH/Marina system

    Author : Benjamin Lagemann; [2019]
    Keywords : added wave resistance; CFD; Courant-adapted time step; Euler ˛flow; FINE Marine; inviscid flow; k-ω SST-Menter; KVLCC2; RANS; regular waves; seakeeping; sub-cycling acceleration; time discretization; viscous flow;

    Abstract : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. READ MORE
