  1. 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 : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 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; Ecology and Evolution; ekologi och 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.

  2. 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; []

    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

  3. 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 : NATURAL SCIENCES; NATURVETENSKAP; Voice Range Profile VRP ; Phonetogram; Voice Field; Voice quality; Singing voice; Voice synthesis; Clinical voice assessment; Sound level measurement; Maximum Entropy; Speech and Music Communication; Tal- och musikkommunikation;

    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

  4. 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.

  5. 5. The high dynamic range imaging pipeline : Tone-mapping, distribution, and single-exposure reconstruction

    Author : Gabriel Eilertsen; Jonas Unger; Rafał Mantiuk.; Anders Ynnerman; Erik Reinhard; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; high dynamic range imaging; tone-mapping; video tone-mapping; HDR video encoding; HDR image reconstruction; inverse tone-mapping; machine learning; deep learning;

    Abstract : Techniques for high dynamic range (HDR) imaging make it possible to capture and store an increased range of luminances and colors as compared to what can be achieved with a conventional camera. This high amount of image information can be used in a wide range of applications, such as HDR displays, image-based lighting, tone-mapping, computer vision, and post-processing operations. READ MORE
