    Sammanfattning : The rapid development of computing technology has made powerful tools, such as finite element codes, available for more and more companies. The use of simulation tools, predictive engineering, is a prerequisite today in product development. LÄS MER

  3. 12. Species extinctions in food webs : local and regional processes

    Författare :Anna Eklöf; Bo Ebenman; Peter Münger; Marcel Holyoak; Linköpings universitet; []
    Nyckelord :Extinction; food web; metacommunity; dispersal; species loss; migration; habitat fragmentation; connectance; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Loss of biodiversity is one of the most severe threats to the ecosystems of the world. The major causes behind the high population and species extinction rates are anthropogenic activities such as overharvesting of natural populations, pollution, climate change and destruction and fragmentation of natural habitats.

  5. 14. Dynamics of ecological communities in variable environments : local and spatial processes

    Författare :Linda Kaneryd; Bo Ebenman; Peter Münger; Michael S. Fowler; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The ecosystems of the world are currently facing a variety of anthropogenic perturbations, such as climate change, fragmentation and destruction of habitat, overexploitation of natural resources and invasions of alien species. How the ecosystems will be affected is not only dependent on the direct effects of the perturbations on individual species but also on the trophic structure and interaction patterns of the ecological community.

  7. 15. Housing demand models and housing market models for regional and local planning

    Författare :Björn Hårsman; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : I rapporten presenteras en metod som kan användas vid arbete med bostadsbyggnadsprogram på lokal och regional nivå. Ett modellpaket har utarbetats. Det består av en modell för hushållssammansättning, en modell för bostadsefterfrågan och en modell för att ge en bild av konkurrensen på bostadsmarknaden.. LÄS MER
