  1. 6. Scenario-based multi-zone approach of wind power for steady-state network studies

    University essay from KTH/Elektriska energisystem

    Author : ARNAUD SCHÜLKE; [2015]
    Keywords : ;

    Abstract : The installed wind power capacity has increased rapidly over the last decades and wind power now has a strong impact on the European electric system. The development of wind power is expected to continue in the coming decades and it is therefore crucial to correctly take it into account in network simulations of the future system. READ MORE

  3. 7. Using digital repeat photography for monitoring the regrowth of a clear-cut area

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Keywords : Physical Geography and Ecosystem Science; scene illumination; PhenoCam; Norunda; near-surface remote sensing; NDVI; digital images; Chromatic coordinates; clear-cut; Earth and Environmental Sciences;

    Abstract : Sammanfattning Digitala övervakningskameror har tidigare använts inom fenologisk forskning för att kunna mäta grönskan i trädkronor. Man har under en längre tid kunnat koppla lövträdets årscykel till klimatförändringar och på så sätt haft ett starkt incitament att studera sambandet. READ MORE

  4. 8. Polygon ponds and their ostracode assemblages as bioindicators in the Indigirka Lowland (north-east Siberia)

    University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Andrea Schneider; [2013]
    Keywords : arctic limnology; polygon ponds; biological indicators; freshwater ostracods; stable water isotopes;

    Abstract : Freshwater ostracods (crustacea, ostracoda) are sensitive to environmental conditions, and are widely used as biological indicators for past and present environmental changes. The abundance and diversity of ostracods from permafrost areas is currently documented in scattered records with incomplete ecological characterizations. READ MORE

  5. 9. Aerosol Measurements and Analysis

    University essay from Lunds universitet/Fysiska institutionen

    Author : Maj Blomdell; Ida Lundin; [2012]
    Keywords : Aerosol particles; particle size distributions; diurnal variations.; Physics and Astronomy;

    Abstract : Abstract The greatest source of hazardous airborne particles in an urban environment comes from traffic exhaust. Air pollution has a great impact on human health; estimated to cause 1.3 million deaths worldwide per year. About half of all mortality caused by air pollution can be linked to motorized traffic.

  6. 10. Diurnal variation in methane flux in a low-arctic fen in Southwest Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Bjarne Munk Lyshede; [2012]
    Keywords : geography; physical geography and ecosystem analysis; diurnal; methane; wetland; Arctic; Greenland; Earth and Environmental Sciences;

    Abstract : Popular science: A Day in the Life of a Methane Bog Methane gas is continuously released from wetlands around the world. In Kobbefjord, Greenland the release of methane is low during the cold of winter and higher in warm summer months. But the amount released also varies from day to night; a pattern that has to do with both temperature and light. READ MORE
