An Approximate Auction

This paper presents an auction procedure which is of particular interest when short execution times are of importance. It is based on a method for approximating the bidders' preferences over two types of items when complementarity between the two may exist. In particular, linear approximations of the bidders' indifference curves are made. The resulting approximated preference relation is shown to

Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging

Popular Abstract in English Plants, algae and some bacteria are able to harvest solar energy to run chemical reactions by a complex process known as photosynthesis. Crucial molecules in this process are the so-called light-harvesting antennas. These antennas contain large amounts of pigments, such as chlorophyll, that are used for solar light absorption. Moreover, these pigments are also involved Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored. Over the last 10 years polarization sensitive single molecule methods

The emergence and spread of tick-borne encephalitis virus in scandinavia

Tick-borne encephalitis virus (TBEV) is a high-impact pathogen with approximately 12,000 diagnoses annually in Eurasia. The virus causes a variety of clinical manifestations, with neurological symptoms in up to 30% of the patients. Lethality in Europe is <2% but post-encephalitis syndrome is seen in over 40% of the infected patients and results in substantial impairment in quality of life. Over th

Energy Efficient Processes for the Production of Gaseous Biofuels - Reforming and Gas Upgrading

Popular Abstract in Swedish Arbetet som presenteras i denna avhandling handlar om att utveckla nya processer för att producera gasformiga biobränslen som är mer energieffektiva än de som används idag. Genom att göra processerna mer energieffektiva kan kostnaden för att producera biobränslen minskas. En lägre produktionskostnad för biobränslet gör det lättare att ersätta fossila bränslen med förnyeReplacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. One way of making biofuels more competitive with fossil fuels is by reducing the production cost. As most of the p
