11. Light propagation and photonic functionalization of semi-ordered material (transparent wood)
Sammanfattning : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. LÄS MER
12. Sensitivity Analysis and Material Parameter Estimation using Electromagnetic Modelling
Sammanfattning : Estimating parameters is the problem of finding their values from measurements and modelling. Parameters describe properties of a system; material, for instance, are defined by mechanical, electrical, and chemical parameters. Fisher information is an information measure, giving information about how changes in the parameter effect the estimation. LÄS MER
13. Studies on Industrial-Scale Thermal Modification of Wood
Sammanfattning : Wood as a raw material is useful for many purposes even though some properties are less than optimal, for example, dimensional stability and durability. These characteristics can however be improved by different treatment methods. LÄS MER
14. Wood colour related to kiln drying
Sammanfattning : Raised temperature in artificial drying has led to some changes of wood products such as colour and strength etc. For special treatment of wood-products with clearly modified properties, among them colour, is often high temperature and steam used industrially. LÄS MER
15. Wood shrinkage in CT-scanning analysis
Sammanfattning : 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. LÄS MER
