  1. 21. Crystal structures of 1,4-ethanonaphthalenes : studies of Diels-Alder adducts of 2,4-cyclohexadienones

    Författare :Bengt Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The present summary concerns crystal structure investigations of the 1,4-ethanonaphtha1ene class of compounds. The structures of eight such compounds have been determined by the present author and coworkers. LÄS MER

  3. 22. Characterization of Micro-Structures in Materials

    Författare :Henrike Häbel; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clustering; colloidal nanoparticle gels; image analysis; mass transport; point pattern; polymer blended films; pore shape; polymer blended films;

    Sammanfattning : On developing the next generation sustainable soft materials, it is often crucial to understand and control their properties and function. Whereas a characterization of three-dimensional data is desirable in corresponding studies, often two-dimensional data are less time consuming to obtain. LÄS MER

  4. 23. Uncertainty and Robustness in Aerospace Structures

    Författare :Anders Forslund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; geometry assurance; robust design; Geometrical variation; uncertainty quantification;

    Sammanfattning : Engineering is not an exact science. In fact, all engineering activity contain some degree of assumption, simplification, idealization, and abstraction. When engineered creations meet reality, every manufactured product behaves differently. This variation can be detrimental to product quality and functionality. LÄS MER

  5. 24. The Tjårrojåkka apatite-iron and Cu (-Au) deposits, northern Sweden : products of one ore forming event

    Författare :Åsa Edfelt; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The Tjårrojåkka area is located about 50 km WSW of Kiruna, northern Sweden, and hosts one of the best examples of spatially related apatite-iron (Kiruna type) and Cu (-Au) deposits in Sweden. The results from this project show that the two deposits are genetically related and indicate the presence of a younger, previously unknown, 1780 Ma generation of apatite- iron ores in northern Sweden.

  7. 25. The partial element equivalent circuit method : modeling and experimental verification of PCB structures

    Författare :Jonas Ekman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : To help products comply with international Electromagnetic Compatibility (EMC)regulations or as a help in a design process numerical simulation of electromagnetic (EM) characteristics are a valuable tool. With the development of high-speed computers the complexity of EM simulation programs and the systems they can simulate has increased considerable. LÄS MER
