  1. 11. 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. 12. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dana Lüdemann; [2020]
    Keywords : aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

    Abstract : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

  4. 13. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Sohail Anwar; [2020]
    Keywords : Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Abstract : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). READ MORE

  5. 14. Invasive species in Weddell Sea : Effects on food web structure

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Inger-Marie Wohlfarth; [2020]
    Keywords : Centrality; Climate change; Food webs; Google PageRank; Invasive species; Structure; Weddell Sea;

    Abstract : The cold water of Antarctica has a unique endemic fauna, where durophagous predators are rare or absent. Due to climate change the water is heating up and the predators have begun to return to the Southern Ocean, which could bring a lot of changes to the food web. There is a high risk it will lead to losses in the unique marine fauna of Antarctica. READ MORE

  6. 15. Plastic ingestion and diet composition in two common fish species from the Swedish Skagerrak

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Danja Fritscher; [2019]
    Keywords : microplastic; plastic ingestion; whiting; dab; diet composition; enzymatic tissue digestion;

    Abstract : Plastic ingestion is supposed to be linked to the feeding behaviour of the fish. Anthropogenic particles were expected to be accidentally ingested by the common dab due to its feeding strategy, which is focused on ground-living organisms. READ MORE
