Design and implementation of a programmable, wideband sonar for sediment mapping

To be able to explore different signal types and processing techniques, apt for sediment mapping, programmable, fully digital profiling systems has been built and tested. The systema are designed to be deployed also at small water depths from small boats, without special handling equipment. The usable frequency band is 100-25000 Hz, limited to approximately 2-10 kHz depending on the projector used

Some strategic national initiatives for the Swedish education in the geodata field

This paper describes national cooperation in Sweden launched by its universities and authorities, aimed at improving geodata education. These initiatives have been focused upon providing common access to geodata, the production of teaching materials in Swedish and organizing annual meetings for teachers. We argue that this type of cooperation is vital to providing high quality education for a poor

Utbildningssegregation och självsortering : Om gymnasieval, genus och lokala praktiker

Popular Abstract in Swedish Denna avhandling utforskar och analyserar segregation och självsortering i utbildning. Den syftar till att diskutera hur detta relateras till genus, individualisering och unga mäns och kvinnors positioneringar i lokala praktiker, genom val av gymnasieutbildning. Den fokuserar hur unga män och kvinnor hanterar och anpssar sig till det förändrade senmoderna samhället. AvThis thesis explores and analyzes segregation and self-sorting in education. It aims at discussing how this relates to gender, individualization and young men and women's positionings in local practices, through choices of upper secondary school education. It focuses on how young men and women cope with and adapt to the changing society in late modernity. The thesis is based on three empirical st

Linkage maps in studies of genetic variation - examples from Beta vulgaris

Today, most studies of genetic variation utilise molecular markers, making it possible to detect variation at the DNA level. This has greatly facilitated studies of genetic variation in population and evolutionary genetics, systematics and transmission genetics. By studying the inheritance of molecular markers in crosses, it is possible to map the markers, i.e. to determine their genomic positions
