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

    Författare :Johan Skog; Olav Höjbö; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : In the Nordic countries, sawlogs are typically sorted upon arrival at the sawmill based on species and dimension. By processing batches of logs with similar size, the sawing process becomes more efficient; the need to change sawing pattern between individual logs is reduced, and the handling of sawn goods is simplified, since the number of different dimensions produced simultaneously decreases.

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

    Författare :Johan Skog; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : 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. LÄS MER

  4. 4. The quest for new improved adenovirus gene therapy vectors against glioma tumours

    Författare :Johan Skog; Göran Wadell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gene therapy; virology; adenovirus; glioma; glioblastoma; Genterapi; virologi; adenovirus; gliom; glioblastom; Virology; Virologi;

    Sammanfattning : Gene therapy has received much attention the last decade as a method to correct a number of disorders arising from a defective gene. Gene therapy can be defined as the introduction of a functional genetic element into a cell for a therapeutic purpose. LÄS MER

  5. 5. Towards better understanding of forestry-wood chain simulation through visualization and interactivity

    Författare :Peter Bomark; Johan Skog; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träproduktutveckling; Wood Products Engineering;

    Sammanfattning : Simulation studies performed on the forestry-wood chain trend towards either complicated calculations on large data-sets, statistical exercises on endless production data, optimisations on specific sub domains, or a combination of the above. The studies are often presented through graphs showing how scalars such as value, profit, or yield fluctuate when parameters of the simulation model are tweaked. LÄS MER
