Popular Abstract in Swedish Med snabbare och pålitligare analysresultat finns stora möjligheter till ett ökat utnyttjande av avfallsresurser för produktion av förnybar energi. Resultat från min forskning gör det möjligt att analysera råvaror för biogasproduktion med större säkerhet och med möjligheten att få upp till nio gånger snabbare resultat. Produktion av biogas har under den senaste tiden öA sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production.

The research report details the current outcomes of an investigation into ways to improve the control and use of electricity for both electric utilities and residential end-users. These improvements can be achieved through electrical control possibilities where specific electrical devices could be either removed or time-shifted to less demanding periods. Two-way communicable electricity meters had

Posture control performance was quantified in three variables (swiftness, stiffness, damping). Subjects were tested with a force platform recording body sway induced by vibrators attached to the calf muscles. Parameter estimation was made with identification of a transfer function representing the stabilized inverted pendulum. It is conjectured that the state feedback parameters identified are sui

This paper presents a toroidal inductor integrated in a standard 0.13 /spl mu/m CMOS process. A very simple /spl Pi/ model for low frequencies is derived from 1-port and 2-port measurements, and a decent matching with general theory is observed. The coil exhibits an inductance of 1.1nH up to 20GHz (physical limit for the measurement equipment) and a quality factor approaching 10 at 15GHz. No self-

Many universities are actively promoting scholarly inquiry into teaching and learning to improve education. Strategies used may involve support for development projects, teaching awards and academies. The Faculty of Medicine, Lund University, Sweden, has developed a Teaching Academy with criteria for membership founded in Scholarship of Teaching and Learning (Kreber, 2002; Trigwell & Shale, 20

In this paper 3D electromagnetic simulations of an antenna array have been performed. The array is intended for automotive radar applications at 24 GHz. It is constructed from dipole antenna element patches, which are fed in the center by a differential signal. The dipole antenna element patches are simulated assuming a standard off the shelf substrate. They have a standing wave ratio less than 3
