While traditionally treated separately, the research disciplines dealing with electromagnetic fields respectively continuum mechanics are naturally connected. Not only are the basic equations formulated in a similar way, but the presence of electromagnetic fields affect the balance equations of continuum mechanics and likewise, the presence of material continua affect the electromagnetic fields

In a previous paper, we showed how classical ideas for dynamicprogramming in discrete networks can be adapted to hybrid systems. The approach is based on discretization of the continuous Bellman inequality which gives a lower bound on the optimal cost. The lower bound is maximized by linear programming to get an approximation of the optimal solution.In this paper, we apply ideas from infinite-dime

I en tid där det allmänna politiska intresset tycks vara vikande, har många förhoppningar knutits till de nya kommunikationskanalernas demokratiska potential. Dessa förhoppningars eventuella realiserande är ena utgångspunkten för detta arbete. Den andra stödjepunkten är den pågående regionaliseringsprocessen i Sverige, med särskilt fokus på Skåne- och Kalmarregionerna. Bland andra drivkrafter bako

Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in

The substitution in varying amounts of strontium (Sr) for calcium in the alpha tricalcium phosphate (α TCP) structure was investigated. The effects on the reactivity towards the formation of hydroxypalatite on hydration were also studied. The prepared α-TCP and the fully hydrated α-TCP powders were characterized by means of X-ray diffraction and the CuKα1 radiation. It was found that the alpha for

In this paper we evaluate the use of parallel interleavers for user separation in coded IDMA systems. The parallel interleavers have previously been evaluated for uncoded systems, and we here present extended results for the coded case. The new results are important for real systems, as they will most likely use performance enhancing channel coding. The parallel interleavers are designed to remove

Politics are not only about interests and institutions but discourses as well. Discourses are (dominant) ideas, concepts and categorisations in a society that give meaning to reality and that shape the identities, interests and preferences of individuals and groups. The assumption of this chapter is that forest discourses are constitutive to global forest politics. Three forest-related types of di

The xylose-fermenting capacity of recombinant Saccharomyces cerevisiae carrying XYL1 and XYL2 from Pichia stipitis, which encode xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, is poor due to high xylitol formation. Whereas, P. stipitis exhibits high ethanol yield on xylose, the tolerance towards inhibitors in the lignocellulosic hydrolysate is low. A recombinant strain posses
