  1. 36. Modelling and Trajectory Planning for a Small-Scale Surface Ship

    University essay from Linköpings universitet/Reglerteknik

    Author : Gustav Zetterqvist; Fabian Steen; [2021]
    Keywords : Marine vessel; Ship; Modelling; Model estimation; Trajectory planning; Optimal control;

    Abstract : Autonomous ships are one way to increase safety at sea and to decrease environmental impact of marine traveling and shipping. For this application, a good representation of the environment and a physical model of the ship are vital components. READ MORE

  3. 37. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    University essay from KTH/Betongbyggnad

    Author : Mohammad Mustafa Angar; [2020]
    Keywords : Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Abstract : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. READ MORE

  4. 38. Aeroelastic flutter analysis with varying level of accuracy

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Nils Voigt Dahl; [2020]
    Keywords : flutter; aeroelasticity; aeroelastic; aerodynamics; Technology and Engineering;

    Abstract : Flutter prediction is a vital part of aircraft development which requires efficient and accurate analysis methods. Saab AB Aeronautics is currently using linear analysis based on the panel method and nonlinear analysis using their in-house CFD software program. These methods are in contrast to one another in terms of computing time and accuracy. READ MORE

  5. 39. Carbon capture from reheating furnaces in the Swedish steel industry : evaluation of techno-economic feasibility

    University essay from Luleå tekniska universitet/Energivetenskap

    Author : Anna Haglund; [2020]
    Keywords : Carbon capture; CCS; Swedish steel indusrty; post-combustion;

    Abstract : The reduction of greenhouse gas emissions is important to keep climate change under control. One of the largest CO2 emitters of the Swedish industries is the steel industry. This is, among others, due to the need of heat treatments and reheating processes depending on high temperatures and fossil fuels. READ MORE

  6. 40. Conceptual and Control System Design of a Lagrangian Float

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

    Author : Anna Madlener; [2020]
    Keywords : ;

    Abstract : Lagrangian floats are autonomous drifting buoys that ideally behave identicalto the surrounding water particles in the water column. Existing examples ofLagrangian floats are often costly and heavy, carrying expensive sensor anddata collection equipment, which prevents their scalability to larger fleets orbroader usage. READ MORE
