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

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

3. Machine Learning for Appearance Grading of Sawn Timber using Cameras and X-ray Computed Tomography
Abstract : This doctoral thesis deals with a new approach for the appearance grading of sawn timber adapted to the requirements of modern sawmilling industries and timber market situations. Appearance grading of sawn timber allows wood products to be made with a specific visual style due to wood features such as knots. READ MORE

4. Agro-industry feedstock and side stream materials for wood panel manufacturing
Abstract : Wood-based panels are indispensable in many areas, such as the construction industry and furniture production. The intensified demand for renewable materials, rising wood prices and increasing protection zones of forest areas make the wood panel industry consider alternative raw materials. READ MORE

5. Towards better understanding of forestry-wood chain simulation through visualization and interactivity
Abstract : 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. READ MORE
