  1. 21. The Integration of 3D Geodata and BIM Data in 3D City Models and 3D Cadastre

    Författare :Jing Sun; Kent Eriksson; Anders Östman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D geodata; BIM; city models; 3D cadastre; geometric quality; CityGML; LADM; laser scanning; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

    Sammanfattning : The initial geographic information system (GIS) and building information modelling (BIM) are designed and developed independently in order to serve different purposes and use. Within the prolific increase and growing maturity of three-dimensional (3D) technology, both 3D geodata and BIM data can specify semantic data and model 3D buildings that are prominent for the 3D city models and 3D cadastre.

  3. 22. Improving trace metal characterisation of ore deposits through multi-modal, multi-scale, and multi-dimensional micro-analysis

    Författare :Mathis Warlo; Christina Wanhainen; Glenn Bark; Alan R Butcher; Nigel Cook; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ore Geology; Malmgeologi;

    Sammanfattning : The variety and amount of metals consumed by human society is ever increasing. Meeting the demand requires exploration for new ore deposits, efficient production of active mines, and improved efficiency in metal recycling. A key element in mining-related enterprises is the improvement of ore characterisation. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SiGe; Esaki Diodes; classical mechanics; quantum mechanics; relativity; termodynamik; relativitet; kvantmekanik; statistisk fysik; Matematisk och allmän teoretisk fysik; thermodynamics; gravitation; statistical physics; GaAs; Mathematical and general theoretical physics; Resonant Tunneling Permeable Base Transistors; Resonant Tunneling Diodes; klassisk mekanik; Fysicumarkivet A:2004:Lind;

    Sammanfattning : This thesis concerns different kinds of tunneling based devices all showing negative differential resistance. The thesis is divided in three parts, resonant tunneling transistors, Esaki diodes and coupled zero dimensional systems. LÄS MER

  5. 24. Norm inequalities of Hardy and Pólya-Knopp types

    Författare :Elena Ushakova; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : This PhD thesis consists of an introduction and six papers. All these papers are devoted to Lebesgue norm inequalities with Hardy type integral operators. Three of these papers also deal with so-called Pólya-Knopp type inequalities with geometric mean operators instead of Hardy operators. LÄS MER

  7. 25. Efficient Methods for Volumetric Illumination

    Författare :Frida Gyllensvärd; Anders Ynnerman; Anders Persson; Markus Hadwiger; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Modern imaging modalities can generate three-dimensional datasets with a very high detail level. To transfer all the information to the user in an efficient way there is a need for three-dimensional visualization. LÄS MER
