  1. 26. Gåvan i Gnosjö – Företagares relationer i ett industriellt distrikt

    Författare :Glenn Sjöstrand; Sven-Åke Lindgren; Göran Brulin; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industrial district; economic sociology; new sociological institutionalism; gift-economy; flexibility; coordination; social capital; social control; norms of exchange.; Sociology; Sociology;

    Sammanfattning : In the growing body of research on industrial districts, focus is usually on trying to explain the economic outcomes of the configuration of formal and informal economic and social organisations specific to these districts. A general way to explain the outcomes is by referring to the “culture” in which economic and social exchanges take place without specifying what culture means and what it is in culture that affects the economic outcomes.

    Författare :Jonas Sjöstrand; Anders Björner; Christian Krattenthaler; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; partition shape; sign-imbalance; Robinson-Schensted correspondence; chess tableau; restricted word; cylindrical lattice walk; Poincaré polynomial; Bruhat interval; rook polynomial; pattern avoidance; partitionsform; teckenobalans; Robinson-Schensted-korrespondens; schacktablå; begränsade ord; cylindriska latticestigar; poincarépolynom; bruhatintervall; tornpolynom; mönsterundvikande permutation; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis deals with enumerative combinatorics applied to three different objects related to partition shapes, namely tableaux, restricted words, and Bruhat intervals. The main scientific contributions are the following. LÄS MER

  4. 28. Reconciling gene family evolution and species evolution

    Författare :Joel Sjöstrand; Jens Lagergren; Nicolas Lartillot; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Bioinformatics; Phylogenetics; Phylogenomics; Comparative genomics; Evolutionary biology; datalogi; Computer Science;

    Sammanfattning : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

  5. 29. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation

    Författare :Jakob Sjöstrand; Leif Kari; Ines Lopez Arteaga; Per Erik Austrell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dry clutch system; Engagement; Disengagement; Dry-friction; LuGre friction model; Heavy-truck powertrain; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. LÄS MER

  7. 30. Decision Support Model for a Sustainable Regional Water Supply

    Författare :Karin Sjöstrand; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-criteria decision analysis; inter-municipal cooperation; drinking water supply; cost-benefit analysis; decision support; regionalization; sustainability; economic valuation;

    Sammanfattning : Water supply provision has traditionally been a municipal responsibility. However, environmental, social and economic drivers are now making it more attractive to manage the water services in a more aggregated way. LÄS MER
