To meet the demands of high electrical efficiencies in combination with low emissions for gas turbine-based power plants, wet cycles have gained new interest. The combustion chamber is a key component in such a power plant. Detailed investigations are necessary to gain insight into the formation of hazardous emissions such as CO and NOx. In this paper, computational fluid dynamics (CFD) has been e

There are many fashion words in AI, such as introspection, reflection, metalanguage, belief and intention. The usual way of looking at such concepts is proof theoretical even if it is not at all clear that these concepts can be described in a formal language. I shed light on some of these concepts from a semantical point of view, and show that it is impossible to describe them to a computer. This

Widespread availability of location aware devices (such as GPS receivers) promotes capture of detailed movement trajectories of people, animals, vehicles and other moving objects, opening new options for a better understanding of the processes involved. In this paper we investigate spatio-temporal movement patterns in large tracking data sets. We present a natural definition of the pattern 'one ob

Much research on SMEs is aimed at researching SMEs after the fact that they have become SMEs. However all SMEs as well as larger companies start as an idea in the head or heads of one or many persons - the prospective entrepreneurs. The purpose of this paper is to investigate how SMEs can be created by transforming ideas into real companies. More specifically we will investigate if and how Univers

Popular Abstract in Swedish Kunskapsarbete framställs ofta som något som präglas av dolskhet eller oklarhet: produkten som säljs är oklar, resultatet är oklart och även själva arbetsprocesserna framställs ofta som oklara. Detta påverkar i sin tur den styrning som man kan förvänta sig i kunskapsintensiv verksamhet: en styrning som ofta handlar om personalen mer än om arbetet. I denna studie problemKnowledge work is often portrayed as hidden or ambiguous: an ambiguous product is sold, ambiguous results are delivered, and work processes are ambiguous. This in turn affects the type of management expected in knowledge-intensive organisations, where emphasis is on managing people rather than work. In this study, the organisation of knowledge work is discussed and problematized through analysis o

This paper focuses on characteristics of out-of-school activities in Sweden and how they have been institutionally changed. In Sweden, childcare is now regarded as a part of life-long education and understood in a context of children’s rights, rather than parents’ rights. Sweden has experienced massive reforms of childcare. One of the major reforms is the integration of childcare and education.Amo

Analytical Multiple-Input Multiple-Output (MIMO) models are often attractive due to their low complexity when analyzing possibilities and limitations in the system. In this paper we outline a a possible dual link extension of an analytical MIMO channel model and investigate its suitability based on measurements of a dual link MIMO scenario. The extension is based on the correlation matrix distance
