1. 1. An X-ray LogScanner : a tool for control of the sawmill process

   Författare :Stig Grundberg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : Wood is a biological material with great variability. Every piece of wood is a unique individual. The great challenge in the wood products manufacturing process has always been to select pieces of wood with properties that fulfil the product requirements. LÄS MER

3. 2. X-ray computer tomography based numerical modelling of fibre reinforced composites

   Författare :Robert Auenhammer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray computer tomography; Finite element modelling; Segmentation; Composites;

   Sammanfattning : Non-crimp fabric reinforced polymers are commonly used to manufacture the load carrying parts in wind turbine blades. Since wind turbine blades have a large material usage, the favourable stiffness to price ratio of non-crimp fabric reinforced polymers is highly attractive for manufactures. LÄS MER

4. 3. Segmentation of knots : a problem in 3D X-ray scanning of logs

   Författare :Katarina Flood; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis investigates the possibilities of using 3D X-ray tomography to detect and segment knots in logs. In the sawmill process this should be done previously to the sawing the log into boards. LÄS MER

5. 4. Degenerative changes of the human temporomandibular joint : A radiological, microscopical, histomorphometrical and biochemical study

   Sammanfattning : In five autopsy specimen studies human temporomandibular joints were investigated by conventional tomography, macroscopy, and microscopy for degenerative changes, in particular erosive hard-tissue changes.In the microscopical evaluation special attention was paid to the calcified cartilage.

7. 5. Multimodal Imaging of Anisotropic Hierarchical Materials

   Författare :Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomaterials; Hierarchical Materials; Multimodal Imaging; Birefringence; X-Ray Scattering;

   Sammanfattning : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. LÄS MER
