Kort sammanfattning: Energimyndigheten, Vetenskapsrådet och Vinnova har stött ESS Skandinavien Sekretariatet med 3 Mkr för att undersöka hållbara energi¬lösningar. Resultatet har blivit att ännu större resurser har bidragits från samarbetande industri. Arbetet är fortfarande i ett tidigt skede av utvecklingen, men preliminära beräkningar visar att besparingarna för ESS kan uppgå till fyra gånger dAbstract: Energimyndigheten, Vetenskapsrådet and Vinnova have supported the ESS Scandinavia Secretariat with 3 MSEK to explore sustainable energy solutions. The result has been that even greater resources have been contributed by cooperating industry. The work is still in early stages of progress, but preliminary calculations indicate that the savings for ESS might amount to four times the initial

The extinction paradox states that a perfectly electric conducting target which is large compared to the wavelength removes from the incident radiation exactly twice the amount of power it can intercept by its geometrical cross section area. In this paper, the extinction paradox is generalized to include temporally dispersive material parameters with finite values of the permittivity and the perme

Forty years ago, Viterbi published upper bounds on both the first error event (burst error) and bit error probabilities for Viterbi decoding of convolutional codes. These bounds were derived using a signal flow chart technique for convolutional encoders. In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 convolutional enc

In the present work, surface thermometry using a method based on the spectroscopy of inorganic luminescent material was applied in the afterburner of a full-size aircraft jet engine. The technique uses laser-induced emission from thermographic phosphors for nonintrusive remote temperature diagnostics in combustion applications with high sensitivity and accuracy. A phosphor material having suitable

Various forms of supply chain management (SCM) research have been carried out in many different manufacturing or industrial settings over the last decades. However, less research exist concerning supply chain management in the service industry. Yet, definitions of supply chain management as they pertain to the service industry are only slightly different than those definitions of SCM in manufactur

Popular Abstract in Swedish Dagens samhälle är väldigt beroende av fordon av olika slag. Aldrig förr har människor rest till olika delar av världen, så mycket som idag. Den enorma mängden resors och transporter som sker varje dag är en tung belastning för vår natur. Bilar och lastbilar, som ökar i antal varje dag, släpper ut giftiga avgaser på vägarna och flygplan förbrukar enorma mängder fossilt Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. Today there are several solutions to meet the demand for better fuel economy
