  2. 1. Microclimate at range margins : Consequences for boreal forest understory species

    Author : Caroline Greiser; Kristoffer Hylander; Johan Ehrlén; Eric Meineri; Miska Luoto; Alistair Jump; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microclimate; species distribution; range dynamics; boreal forest; canopy cover; topography; soil moisture; air humidity; bryophytes; lichens; vascular plants; biotic interactions; forest management; biodiversity conservation; ekologi och evolution; Ecology and Evolution;

    Abstract : A warmer climate will shift species distributional range margins poleward, but near-ground microclimates may modify these shifts. Cold-adapted northern species at their rear edge may survive locally in microrefugia with a colder microclimate, and warm-adapted southern species at their leading edge may colonize stepping stone habitats with a warmer microclimate.

  4. 2. Proactive Range Management : A Timber Supplier’s Efforts to Influence the Product Assortment of Builders’ Merchants

    Author : Daniel Ellström; Jakob Rehme; Tomas Nord; Daniel Nordigården; Daniel Chicksand; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Different builders’ merchants demand a variety of products, and no effort has yet been made to coordinate these demands. Therefore, suppliers of timber to builders’ merchants are facing a problem in terms of requirements for a product range that is too extensive. READ MORE

  5. 3. Mapping Individual Voice Quality over the Voice Range : The Measurement Paradigm of the Voice Range Profile

    Author : Peter Pabon; Sten Ternström; Maria Södersten; Ingo Titze; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Voice Range Profile VRP ; Phonetogram; Voice Field; Voice quality; Singing voice; Voice synthesis; Clinical voice assessment; Sound level measurement; Maximum Entropy; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : The acoustic signal of voiced sounds has two primary attributes: fundamental frequency and sound level. It has also very many secondary attributes, or ‘voice qualities’, that can be derived from the acoustic signal, in particular from its periodicity and its spectrum. READ MORE

  6. 4. Wide Range Isolated Power Converters

    Author : Muhammad Abu Bakar; Kent Bertilsson; Johan Sidén; Jorge Garcia; Mittuniversitetet; []
    Keywords : Power converters; Resonant converters; wide range converter; stable performance;

    Abstract : Power electronics technology is rapidly growing in most industrialapplications. There is an increasing demand for efficient and low profilepower converters in the industry like automotive, power grids, renewableenergy systems, electric rail systems, home appliances, and informationtechnology.

  7. 5. Extending dynamic vegetation models to simulate range shifts

    Author : Deborah Zani; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamic vegetation model; range shift; migration; paleovegetation;

    Abstract : In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). READ MORE
