2. 1. Wood shrinkage in CT-scanning analysis

   Author : José Couceiro; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

   Abstract : Computed tomography (CT) can be used to study wood-water interactions in differentways, such as by determining wood moisture content (MC). The determination of MCrequires two CT images: one at the unknown moisture distribution and a second one ata known reference MC level, usually oven-dry MC. The two scans are then compared. READ MORE

4. 2. X-ray computed tomography to study moisture distribution in wood

   Author : José Couceiro; Lars Hansson; Mike Milota; Luleå tekniska universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

   Abstract : X-ray computed tomography (CT) has been used as an analysing tool for different features in wood research since the beginning of the1980s, but it can also be used to study wood-water interactions in different ways, such as by determining wood moisture content (MC). The determination of wood MC with CT requires two CT images: one at the unknown moisture distribution and a second one at a known reference MC level, usually at oven-dry condition. READ MORE

5. 3. Four-dimensional computed tomography and image processing to investigate moisture in wood

   Author : Boris Poupet; Dick Sandberg; José Couceiro; Sara Florisson; Arttu Miettinen; Luleå tekniska universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

   Abstract : Kiln drying is the most energy-consuming operation in the industrial production of sawn timber and optimising the process is necessary to improve its efficiency. A key to achieving this is to speed up the drying, but this must not come at the cost of deteriorating the quality of the sawn timber. READ MORE
