  2. 11. Essays on financial time series models : Stochastic volatility and long memory

    Author : Jonas Andersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; statistik; Statistics;

    Abstract : This work consists of five articles about the statistical aspects of financial time series models. The first three papers investigate and develop the inverse normal Gaussian stochastic volatility (NIGSV) model, initially suggested by Barndorff- Nielsen (1997). READ MORE

  5. 13. Formation, ageing and thermal properties of secondary organic aerosol

    Author : Eva U. Emanuelsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volatile organic compounds; biogenic; anthropogenic; secondary organic aerosol; troposphere; volatility; ozone;

    Abstract : In order to properly represent and predict the effects of aerosol in climate systems, an accurate description of their formation and properties is needed. This thesis describes work done to increase the knowledge of processes and properties of atmospherically relevant secondary organic aerosol (SOA) from both biogenic and anthropogenic origin.

  6. 14. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols

    Author : Åsa M. Jonsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tropospheric chemistry; monoterpenes; ozonolysis; secondary organic aerosol SOA ; G-FROST; AIDA; humidity; temperature; hydroxyl radicals; volatility; pinonaldehyde; climate and health;

    Abstract : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. READ MORE

  7. 15. Physical properties and processes of secondary organic aerosol and its constituents

    Author : Kent Salo; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing;

    Abstract : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. READ MORE
