  3. 22. Faceted conformal antenna arrays analyzed with the uniform theory of diffraction

    Författare :Carina Marcus; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Faceted Conformal Antenna; High-frequency methods; Ray tracing;

    Sammanfattning : Faceted conformal antenna arrays are analyzed with the uniform theory of diffraction (UTD). Parameters such as mutual coupling, scattering parameters, isolated and embedded element patterns are calculated.A ray tracing algorithm for handling rays on a faceted surface, which is needed for the UTD calculations, is also described..

  4. 23. Mechanisms of Uniform Corrosion of Zirconium Alloys in Water and Steam

    Författare :Boel Wadman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Zirconium alloys are used in key components in nuclear reactors, e.g. fuel cladding tubes in pressurised water reactors. Current trends towards extended burnup of the nuclear fuel in these reactors have accentuated the demand for Zr alloys with higher uniform corrosion resistance under irradiation and lower hydrogen absorption.

  5. 24. A Uniform Query Processing Approach for Integrating Data from Heterogeneous Resources

    Författare :Merja Karjalainen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Query processing; Functional data model; Rewrite rules; Data integration;

    Sammanfattning : Scientists who need to explore several different databases in theirresearch can find it difficult and tedious to extract and combineinformation from various heterogeneous data sources manually.This is a particular problem for researchers in the life sciences,since technical advances in the last decade have resulted in a dramaticincrease in the quantity and variety of data.
