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

    University dissertation from Chalmers University of Technology

    Author : Johan Löfgren; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geovetenskap; Earth sciences; Övrig geovetenskap; Other earth sciences; Teknisk fysik; Engineering physics; Övrig teknisk fysik; Other engineering physics; Global Navigation Satellite Systems; reflected signals; sea-level monitoring; tide gauge; ocean tides;

    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

  2. 2. Validation and time series analysis of global stratospheric data sets

    University dissertation from Chalmers University of Technology

    Author : Ashley Jones; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geovetenskap; Earth sciences; Meteorologi; Meteorology; Övrig geovetenskap; Other earth sciences; Odin; MIPAS; OSIRIS; ozone; validation; stratosphere; remote sensing; data assimilation; Trend; linear regression;

    Abstract : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. READ MORE

  3. 3. Coal and Oil: The Dark Monarchs of Global Energy Understanding Supply and Extraction Patterns and their Importance for Future Production

    University dissertation from Uppsala : Acta Acta Universitatis Upsaliensis

    Author : Mikael Höök; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oil production; coal production; depletion rate; forecasting; energy supply; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap; TECHNOLOGY Industrial engineering and economy Physical planning; TEKNIKVETENSKAP Industriell teknik och ekonomi Fysisk planläggning; TECHNOLOGY Engineering physics Other engineering physics; TEKNIKVETENSKAP Teknisk fysik Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Abstract : The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind.  This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil.

  4. 4. Depletion and decline curve analysis in crude oil production

    University dissertation from Uppsala : Global Energy Systems, Department for Physics and Astronomy, Uppsala University

    Author : Mikael Höök; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; depletion rate; decline curve analysis; crude oil production; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap; NATURAL SCIENCES Physics Other physics Mathematical physics; NATURVETENSKAP Fysik Övrig fysik Matematisk fysik; TECHNOLOGY Engineering physics Other engineering physics; TEKNIKVETENSKAP Teknisk fysik Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Abstract : Oil is the black blood that runs through the veins of the modern global energy system. While being the dominant source of energy, oil has also brought wealth and power to the western world. Future supply for oil is unsure or even expected to decrease due to limitations imposed by peak oil. Energy is fundamental to all parts of society. READ MORE

  5. 5. Particle Emissions from Ships

    University dissertation from Chalmers University of Technology

    Author : Maria Zetterdahl; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle emission; ship emission; marine fuel; liquefied natural gas; LNG; heavy fuel oil; marine diesel oil; SECA; sulphur emission control area; fuel sulphur content; aromatics;

    Abstract : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. READ MORE
