  1. 1. Adaptation of wave power plants to regions with high tides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mohd Nasir Ayob; Uppsala universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy; Tides; Wave Hub; Lysekil research site; Control system; Tidal compensator; Wave energy converter.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The wave energy converter (WEC) developed at Uppsala University is based on the concept of a heaving point absorber with a linear generator placed on the seafloor. The translator inside the generator oscillates in a linear fashion and is connected via a steel wire to a point absorbing buoy. READ MORE

  2. 2. Sea Level Compensation System for Wave Energy Converters

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Valeria Castellucci; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

    Abstract : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. READ MORE

  3. 3. Modelling the middle atmosphere and its sensitivity to climate change

    University dissertation from Stockholm : Meteorologiska institutionen (MISU)

    Author : Andreas Jonsson; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; middle atmosphere; ozone; carbon dioxide; stratosphere; mesosphere; chemical kinetics; atmospheric tides; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi;

    Abstract : The Earth's middle atmosphere at about 10-100 km has shown a substantial sensitivity to human activities. First, the ozone layer has been reduced since the the early 1980s due to man-made emissions of halogenated hydrocarbons. READ MORE

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

    University dissertation from Stockholm : Meteorologiska institutionen (MISU)

    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. Matrixing Aid The Rise and Fall of 'Results Initiatives' in Swedish Development Aid

    University dissertation from Stockholm : Stockholm Business School, Stockholm University

    Author : Janet Vähämäki; Stockholms universitet.; [2017]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accounting; Management Reforms; Results; Development Aid; Donor Practice; Sida; Reform Cycles; Tides of Reforms; Performance Measurement; Performance Management; Business Administration; företagsekonomi;

    Abstract : Reform ideas, such as results measurement and management, tend to come and go in different ‘tides of reforms’. The purpose of this thesis is to increase our understanding of tides of reforms by identifying and discussing mechanisms that drive the rise, as well as the fall, of management reforms. READ MORE
