  1. 1. Combining X-ray and 3D scanning of logs

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Johan Skog; Luleå tekniska universitet.; RISE.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Träteknik; Wood Technology; Manufacturing engineering and work sciences - Manufacturing engineering; Produktion och arbetsvetenskap - Produktionsteknik;

    Abstract : In Scandinavia, sawlogs are typically sorted upon arrival at the sawmill. Presorting of sawlogs according to dimension, e.g., using an optical three-dimensional (3D) scanner, is used to make the sawing process more efficient. READ MORE

  2. 2. Characterization of sawlogs using industrial X-ray and 3D scanning

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Johan Skog; SP Trä. SP - Sveriges Tekniska Forskningsinstitut; Luleå tekniska universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : I Norden sorteras sågtimmer vanligtvis vid ankomst till sågverket, baserat på träslag och dimension. Genom att i följd såga ett stort antal stockar av liknande storlek kan sågningen effektiviseras eftersom behovet att byta postning mellan varje stock minskar och färre dimensioner av sågad vara behöver hanteras samtidigt.

    Abstract : Particleboard was invented to increase the utilization of wood and it soon became an important core material for furniture production. Nowadays, other industries such as the pulp and papermaking industry and the thermal energy recovery industry claim the same type of raw material. READ MORE

  5. 5. Extraction of logging residues for bioenergy effects of operational methods on fuel quality and biomass losses in the forest

    University dissertation from Växjö : Linnaeus University Press

    Author : Bengt Nilsson; Linnéuniversitetet.; [2016]

    Abstract : Wood products play a key role in the transformation to a more sustainable society based on renewable bio-based resources, together with the positive effects on climate mitigation by replacing fossil fuels. However, to increase the use of forest fuel in practice it is important to understand the effects of handling and storage on its quality and removal of nutrients from the forest. READ MORE
