In this paper, a generic electromagnetic model is utilized for arbitrary multiport antennas e.g., vector sensors applied in DOA estimation, which was exploited for the statistical analysis of DOA and polarization estimation. By utilizing the spherical vector wave expansion of the electromagnetic field to completely characterize the multiport antennas a general framework for modelling an antenna co

Popular Abstract in Swedish Det norra barrskogsbältet, även kallat de boreala skogarna, sträcker sig runt hela norra halvklotet. Det utgör en tredjedel av den globala skogsytan, och innehåller hälften av den totala mängden kol finns lagrat i samtliga skogsekosystem. Trots de låga temperaturerna, den korta vegetationssäsongen och en liten mängd inkommande solenergi under året, är dessa ekosystem viIn boreal forests, the main factors limiting biomass production are the harsh climate, which combines a short growing season and low annual levels of incoming solar energy, and the limited availability of nitrogen. These limitations will be directly affected by climate change, and may in turn substantially affect the carbon budget of the boreal forests, the production of wood and biofuel, biodiver

The state of the farming industry in Europe has been put under the spotlight in recent years due to a number of different food scares and disease outbreaks. Many new quality assurance schemes have been formed to accompany the existing environmental monitoring schemes, to give concerned consumers some guarantee when buying food that it is of a good quality and the environmental load of production h

Popular Abstract in Swedish Ett viktigt steg i strävan att ersätta fossila bränslen med biobränslen är ett effektivt utnyttjande av förnyelsebar lignocellulosa. Råmaterialet är restprodukter från skogs- och jordbruksindustrin och består bl. a. av komplexa kolhydrater som cellulosa. Efter nedbrytning till enkla sockermolekyler kan dessa omvandlas till bioetanol genom jäsning. Sockret som extraherasIn 2009 the EU approved two directives as a first initiative towards reducing greenhouse gas emissions and becoming independent of fossil fuels: the Renewable Energy Directive and the Fuel Quality Directive. As a result, the demand for biofuels will increase enormously over the next decade, both nationally and in the entire EU. This huge demand will require a more advanced type of biofuels, produc

Following the theme of this monograph, this paper discusses a dialectic we perceive to subsist between meaningful use and reflection upon use. This dialectic between experiencing use and reflecting upon experiencing use (or thinking, and thinking about thinking) may be considered in the following way. Each of these elements is subject to change. As reflection triggers change in use, and such chang

Popular Abstract in Swedish Avhandlingen är en studie av hur stöd och service organiseras kring fyra barn med funktionshinder och deras familjer. I denna service är normalt flera olika formella organisationer involverade, som barnhabilitering, förskola/skola/särskola, hjälpmedelscentral, assistentorganisationer, sjukvård m fl. Dessutom kan barnets och familjens situation vara komplicerad på många This study explores the organising of services for disabled children and their families in Sweden. It is based on 83 interviews with parents and involved staff surrounding four disabled children, with both physical and intellectual disabilities, and between two and nine years old. Further, 15 meetings between parents and staff were observed, primarily serving as background material. The service pr
