Kombinerade X-bandsanläggningar som väderradar : Jämförelse med etablerade metoder för regnmätning

Studien är en första utvärdering i Sverige av X-bandsteknik som väderradar. Den visar hur flera X-bandsradaranläggningar kan samarbeta och hur regninformationen kan användas för avrinningssimulering. Tekniken öppnar nya utvecklingsmöjligheter för VA-branschen. Det gäller inte minst driften av ledningsnätet, väderstyrning av ledningsnät och reningsverk, samt utvecklingen av publika varningssystem.In this research report, a new methodology has been developed in order to integrate several X-band radar data sets in to one complete set. Furthermore, a direct and an indirect evaluation have been conducted compared to stationary rain gauges and C-band radar. In the indirect analysis, the input data sets were integrated into runoff models for Ellinge and Lundåkra WWTP where the results were compa

Lichenicolous fungi associated with southern Scandinavian Xanthoria calcicola s.lat.

Eleven species of lichenicolous fungi associated with Xanthoria calcicola s.lat. are found in southernmost Scandinavia, i.e., Skåne, the southernmost province in Sweden and southern Denmark. Two species, Didymocyrtis slaptoensis and Pyrenochaeta xanthoriae, are reported as new for the Nordic countries, whereas three species, Didymocyrtis cf. consimilis, Erythricium aurantiacum, and Illosporiopsis

Skräckens eller hoppets bilder? Om synerna i Apokalypsen

Uppenbarelseboken avtäcker med sina fasansfulla syner – sin Apokalyps – vad som ska ske på den yttersta dagen, då allt ont ska förgås och ett nytt rike ska upprättas. Men numera menas ofta med apokalyps enbart den skräckfyllda, mytologiska spådomen om en framtida katastrof. Kan man istället förstå Uppenbarelsebokens syner som en varning, för den katastrof vi själva är med om att skapa här och nu,

Improving EEG-based decoding of the locus of auditory attention through domain adaptation

This paper presents a novel domain adaptation framework to enhance the accuracy of EEG-based auditory attention classification, specifically for classifying the direction (left or right) of attended speech. The framework aims to improve the performances for subjects with initially low classification accuracy, overcoming challenges posed by instrumental and human factors. Limited dataset size, vari

Social media in the context of development : A case study of Dutch NGOs

This paper presents views of six Dutch development NGOs on possibilities and threats of social media for their work. A systematic analysis of the literature and the systematic analysis of the interviews yield an interesting theoretical framework in which social media characteristics are cross-referenced with NGO organisational characteristics. The resulting preliminary framework of emerging themes

On H2 and H-infinity Optimal Control of Mass-Spring Networks with Power System Applications

Electric power systems are undergoing huge changes due to the shift from conventional power production to more renewable-based generation like solar and wind. This is primarily driven by the need to mitigate climate change by reducing CO2 emissions. The shift to more generation from solar and wind will affect the dynamical behaviour of power systems, and consequently how they should be controlled.
