  1. 1. Studies on future Mine Countermeasure Vessels (MCMV)

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Författare :Philip Somehagen; [2023]
    Nyckelord :Concept development; Mine countermeasure vessels; ROV; Sonar; Konceptutveckling; Minjaktsfartyg; ROV; Sonar;

    Sammanfattning : Background Maritime transportation is vital for international trade, and any disruption to this flow can have severe financial and environmental consequences. Ship mines, both old and new, present significant risks as man-made obstacles. LÄS MER

  3. 2. Comparing radar satellites. Use of Sentinel-1 leads to an increase in oil spill alerts in Norwegian waters

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ove Njøten; [2021]
    Nyckelord :Geography; GIS; Satellite; Radar; Oil spill; Earth and Environmental Sciences;

    Sammanfattning : Radar’s ability to detect oil spills through clouds, fog, and darkness is a significant advantage. Oil spill alert services using radar satellites have been in use in Norway for more than 25 years. After introducing two radar satellites Sentinel-1A and 1B in 2015-2016, the number of oil spill alerts has increased by 250% in Norwegian waters. LÄS MER

  4. 3. Skeppssättning och Långröse : En komparativ studie längsmed Norrlands kustområde

    Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Adrian Lindberg; [2020]
    Nyckelord :Stone ship setting; long cairn; Norrland; Nordic Bronze Age; Scandinavia; maritory; the Baltic Sea; Bothnian Sea; Skeppssättning; Långröse; Norrland; Nordisk bronsålder; Skandinavien; maritorium; Östersjön; Bottenhavet;

    Sammanfattning : Through social landscape theory the aim of this thesis is to broaden the understanding of the bronze age monumental graves on the coast of Norrland. Questions about similarities between the stone ship settings and long cairns are analysed by looking at size and placement in the landscape. LÄS MER

  5. 4. Gravskick i Gotländska Skeppssättningar : En osteologisk analys av kremerade ben

    Kandidat-uppsats, Uppsala universitet/Arkeologi

    Författare :Sofya Blinova Högberg; [2019]
    Nyckelord :Stone ships; Ship Setting; Bronze Age; Cremated bones; Gotland; Skeppssättningar; skeppssättning; bronsålder; kremerade ben; Gotland; stora bjers; annelund; lilla hoburga;

    Sammanfattning : This thesis will focus on stone ship settings and the burial practice surrounding them. Over 400 stone ships have been found in Gotland but only 70 of them have been studied and even less osteological analyses have been made. LÄS MER

  7. 5. Efficient seakeeping performance predictions with CFD

    Master-uppsats, KTH/Marina system

    Författare :Benjamin Lagemann; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
