  1. 1. Relationships between nomenclature, phylogenetics and systematics

    Författare :Yann Bertrand; Mikael Härlin; Mieczyslaw Wolsan; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PhyloCode; philosophy; systematics; individuality; natural kind; possible worlds; causal theory of reference; PhyloCode; philosophy; systematics; individuality; natural kind; possible worlds; causal theory of reference;

    Sammanfattning : Systematists have become increasingly aware of the limits imposed by the current system of nomenclature for accurately representing evolutionary relationships and managing efficiently names associated with clades. In reaction, a new system of nomenclature, the PhyloCode is being developed that fully recognizes the historical nature of taxonomy and the importance of the cladistics revolution. LÄS MER

  5. 4. Particle interactions at the nanoscale : From colloidal processing to self-assembled arrays

    Författare :Bertrand Faure; Lennart Bergström; Albert Philipse; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; Materials Chemistry; materialkemi;

    Sammanfattning : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. LÄS MER

  7. 5. On Stability and Surge in Turbocharger Compressors

    Författare :Bertrand Kerres; Andreas Cronhjort; Mihai Mihaescu; Jörg Seume; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Radial Compressor; Stability; Surge; Hurst exponent; Fractals; Machine Design; Maskinkonstruktion;

    Sammanfattning : Turbochargers are used on many automotive internal combustion engines to increase power density. The broad operating range of the engine also requires a wide range of the turbocharger compressor. At low mass flows, however, turbo compressor operation becomes unstable and eventually enters surge.
