  2. 21. Impact of Rossby waves on ozone distribution and dynamics of the stratosphere and troposphere

    Author : Grigory Nikulin; Sheila Kirkwood; Ulrike Langematz; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorology; ozone; wave activity; trends; Brewer-Dobson circulation; Rossby waves; Arctic Oscillation; low ozone events; Meteorologi; Meteorology; Meteorologi; Meteorology; meteorologi;

    Abstract : Several physical mechanisms concerning the impact of Rossby waves on ozone distribution and circulation in the stratosphere and troposphere are studied in the thesis.Summertime total ozone variability over Middle Asia and Northern Scandinavia shows similar wave-like behaviour with typical periods of 10-20 days and amplitudes of 20-50 Dobson units.

    Abstract : In recent years, application of confluent jets for design of ventilation supply devices has been studied. Similarly, numerus studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. READ MORE

  6. 24. Modelling Bidding Behaviour in Electricity Auctions : Supply Function Equilibria with Uncertain Demand and Capacity Constraints

    Author : Pär Holmberg; Nils Gottfries; Chuan-Zhong Li; Mats Bergman; David Newbery; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business and economics; supply function equilibrium; asymmetry; uniqueness; oligopoly; capacity constraint; uniform-price auction; pay-as-bid auction; discriminatory auction; wholesale electricity market; Ekonomi; Business and economics; Ekonomi;

    Abstract : In most electricity markets, producers submit supply functions to a procurement uniform-price auction under uncertainty before demand has been realized. In the Supply Function Equilibrium (SFE), every producer commits to the supply function that maximises his expected profit given the bids of competitors. READ MORE

  7. 25. Statistical Mechanical Studies of Aqueous solutions and Biomolecular Systems

    Author : Fernando Luis Barroso Da Silva; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; highly charged macromolecules; dielectric discontinuity; dissociation constant; Tanford-Kirkwood model; protein mutation; electrostatic interactions; chemical potential; titration; biomolecules; computer simulations; radial distribution function; electrolyte solutions; continuum model.; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : This thesis is concerned with theoretical studies of aqueous solutions and biomolecular systems. Part of the present work is to understand equilibrium solvent and solute properties, while the other part is to study processes that occur in these solutions. READ MORE
