    Sammanfattning : En utgångspunkt för den föreliggande avhandlingen och doktorsstudien är den spridning och ökning av projektarbetsformens tillämpning, som skett sedan mitten av 1900-talet. Det har blivit allt vanligare med så kallade multiprojektmiljöer, dvs. LÄS MER

  3. 17. Three-dimensional structured carbon foam : synthesis and applications

    Författare :Ngoc Tung Pham; Jyri-Pekka Mikkola; Krisztian Kordas; William Siljebo; Dmitry Yu. Murzin; Umeå universitet; []

    Sammanfattning : Recently, due to the unique properties and structures such as large geometric surface area, electrical conductivity and light weight, 3D structured carbon materials have been attracting extensive attention from scientists. Moreover, the materials, which can provide well-defined pathways for reactants to easily access active sites, are extremely useful for energy conversion as well as environmental and catalysis applications.

  4. 18. Tools for Structured Matrix Computations : Stratifications and Coupled Sylvester Equations

    Författare :Andrii Dmytryshyn; Bo Kågström; Volker Mehrmann; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Developing theory, algorithms, and software tools for analyzing matrix pencils whose matrices have various structures are contemporary research problems. Such matrices are often coming from discretizations of systems of differential-algebraic equations. LÄS MER

  5. 19. Genetic variation in structured populations

    Författare :Marina Rafajlovic; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genetic variation; varying population size; effective population size; mutation; recombination; migration; multiple paternity; geographic structure; tests of neutrality; gene tree; species tree;

    Sammanfattning : It is widely acknowledged that the process of speciation in the presence of gene flow between different ecotypes is common in nature. However, the mechanisms underlying speciation are not understood. LÄS MER

  7. 20. Intelligent semi-structured information extraction : a user-driven approach to information extraction

    Författare :Anders Arpteg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificiell intelligens; Informaitonsåtervinning; Artificial intelligence; Computer science; Datavetenskap;

    Sammanfattning : The number of domains and tasks where information extraction tools can be used needs to be increased. One way to reach this goal is to design user-driven information extraction systems where non-expert users are able to adapt them to new domains and tasks. LÄS MER
