  1. 1. Medium Voltage Generation System with Five-level NPC Converters for Kite Tidal Power

    Author : Georgios Mademlis; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maximum Power Point Tracking MPPT ; Neutral point clamped converter NPC ; Medium Voltage Converters; Subsea kite; Voltage balancing; Multilevel Space-Vector-Modulation; Tidal power;

    Abstract : Offshore power generation has emerged as a prominent source of energy and the installed capacity of new plants has been steadily increasing in recent years. Tidal power specifically is a promising renewable energy source which has not been highly exploited yet, despite its distinctive advantages of being predictable and independent of weather conditions.

  2. 2. Local Sea Level Observations Using Reflected GNSS Signals

    Author : Johan Löfgren; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS-R; signal-to-noise ratio; sea level; GNSS; reflected signals; multipath; GPS; GLONASS; tide gauge; phase-delay;

    Abstract : Sea level rise due to global warming is predicted to have a large impact on human society, especially for populations living in coastal regions and on islands. It is therefore of great importance to monitor the sea level and to increase the understanding of the local hydrodynamic and meteorological responses to a global sea level rise. READ MORE

  3. 3. Tidal Inlets Hydraulics and Morphological Modeling: An application to Mundaú Lagoon, Brazi

    University dissertation from Water Resources Engineering, Lund University

    Author : Almir Nunes De Brito Junior; [2020-04-28]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tidal inlets; Numerical modeling; Coastal lagoons; Mundaú Lagoon; Sururu; Sediment transport;

    Abstract : Tidal inlets are narrow channels connecting coastal lagoons to the sea and in this way controlling the exchange of water while serving as navigational pathways. These important components of the coast are also very dynamic environments, having their morphology determined by multiple sediment transport processes, making tidal inlets difficult to model.

  4. 4. Observing Sea Level Using Reflected Global Navigation Satellite System Signals

    University dissertation from Water Resources Engineering, Lund University

    Author : Johan Löfgren; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tide gauge; Global Navigation Satellite Systems; ocean tides; reflected signals; sea-level monitoring;

    Abstract : Sea-level rise due to global warming is predicted to have a large impact on human society, especially for populations living in coastal regions and on islands. It is therefore of great importance to monitor the sea level and to increase the understanding of the local hydrodynamic and meteorological responses to a global sea-level rise. READ MORE

  5. 5. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    University dissertation from Deaprtment of Geology

    Author : Shiyong Yu; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Abstract : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. READ MORE
