Popular Abstract in Swedish Kravhantering är en process för att identifiera, specificera, och underhålla krav för en produkt. Om du inte har rätt krav, spelar det ingen roll hur bra allt annat görs. Detta kan sluta med en perfekt utveckling av fel produkt som kunderna inte vill ha. I marknadsdriven kravhantering, där det inte finns en specifik kund, är strategisk releaseplanering en viktig processIn a competitive environment, as experienced by market-driven organizations, it is important to plan software product releases with time-to-market in mind. To increase the chances of market success, software products need to be released to the market, not only at the right time, but also with higher level of quality than the competitors' products. Thus quality requirements can be seen as a key com

Vapor pressures of five methyl-substituted dicarboxylic acids are inferred from measurements of evaporation rates of sub-micron particles using the TDMA technique at ambient temperatures. Vapor pressures values are given. These vapor pressures are compared witha vailable literature data and withv apor pressures of the un-substituted acids. Our results demonstrate that molecular structure is import

Popular Abstract in English In biotechnological industries, downstream processing is a bottleneck in the complete production process. There is a wish to reduce the costs and therefore one tries to operate separation technology in continuous mode. Conventional SMB is a continuous countercurrent separation process, which is based on mathematical modeling and simulation studies for separation of binIn biotechnological industries, downstream processing is a bottleneck in the complete production process. There is a wish to reduce the costs and therefore one tries to operate separation technology in continuous mode. Conventional SMB is a continuous countercurrent separation process, which is based on mathematical modeling and simulation studies for separation of binary mixtures of components.

This technical note investigates the model reduction problem for mean square stable discrete time Markov jump linear systems. For this class of systems a balanced truncation algorithm is developed. The reduced order model is suboptimal, however the approximation error, which is captured by means of the stochastic L2 gain, is bounded from above by twice the sum of singular numbers associated to the

This research is triggered by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. Under the emerging ‘power by the hour’ paradigm, aero engines are effectively leased to the airlines, with the manufacturing company remaining responsible for their maintenance and r
