  1. 21. Non-dimensional gradient functions for water vapor and carbon dioxide in the marine boundary layer

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Caroline Vahlberg; [2015]
    Keywords : Monin-Obukhov similarity theory; non-dimensional gradient functions; water vapor; carbon dioxide; marine boundary layer; turbulent fluxes; Monin-Obukhov similaritetsteori; dimensionslösa gradientfunktioner; vattenånga; koldioxid; marina gränsskiktet; turbulenta flöden;

    Abstract : A better understanding of the exchange processes taking place over the oceans is of great importance since the oceans cover about 70 % of the Earth’s surface. With better knowledge the turbulent fluxes can be more accurate parameterized, which is essential in order to improve the weather- and climate models. READ MORE

  3. 22. Soot particles from shipping: Analysing emission factors

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Nicklas Mauritzson; [2015]
    Keywords : Ship emission; emission factor; soot; black carbon; measurement; SECA; Gothenburg; Sweden; Earth and Environmental Sciences;

    Abstract : Emissions of air pollutants from shipping in Europe result in about 50 000 premature deaths every year. Soot particles, also called black carbon, are particularly hazardous to human health when inhaled. The adverse health effects are especially a danger in coastal areas, but the particles can travel further away with the wind. READ MORE

  4. 23. The formation of the ion seed population at quasi-parallel shocks in space plasma

    University essay from Uppsala universitet/Rymd- och plasmafysik; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Andreas Johlander; [2014]
    Keywords : ;

    Abstract : Collisionless shocks in space plasmas are known to be capable of accelerating particles to very high energies. Particles are accelerated through a process called Fermi acceleration. However, this process can only act on particles with higher than thermal (suprathermal) energies. READ MORE

  5. 24. Control and operation of a Vertical Axis Wind Turbine

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Tiago Marques; [2014]
    Keywords : Wind turbine control; Supervisory Control and Data Acquisition; PLC programming; LabVIEW; Maximum Power Point Tracking; Hill-Climb search; Technology and Engineering;

    Abstract : Research in wind power generation technology is a topic of high relevance in the context of renewable energy systems. This project aims to develop and implement an automatic operation and control system for an experimental vertical axis wind turbine (VAWT) located at Lunds Tekniska Högskola, in Sweden. READ MORE

  6. 25. Willingness to wind - A panel data study of public policies and municipal factors determining the deployment of wind power in Swedish municipalities

    University essay from Göteborgs universitet/Graduate School

    Author : Emilia Hygstedt; Ulrika Kjellström; [2013-07-01]
    Keywords : ;

    Abstract : In 2009 the Swedish government adopted a national planning goal of 30 TWh wind power by 2020, implying a large expansion is needed from the current level of 7 TWh. The municipal territorial planning monopoly implies that the municipalities have a high degree of independence in the decision of installing wind power. READ MORE
