1. Wood Fingerprints : Recognition of Sawn Wood Products
Abstract : This thesis deals with wood fingerprints and presents ways to track sawn wood products through an industrial process using cameras. The possibility to identify individual wood products comes from the biological variation of the trees, where the genetic code, environment and breakdown process creates a unique appearance for every board.

2. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour
Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

3. Exploring aspects of automation decisions : A study in the Swedish wood products industry
Abstract : The wood products industry is important to Sweden's prosperity, and is currently facing several challenges by increased global competition. To avoid the gradual decline of the industry’s contribution to the country’s revenues and employment opportunities, the Swedish wood products industry needs to increase the proportion of the raw material that is refined.

4. Wood Hemicelluloses - Fundamental Insights on Biological and Technical Properties
Abstract : Hemicelluloses are a group of heterogeneous polysaccharides representing around 30 % of wood where the dominating types are xylans, glucomannans and xyloglucans. Hemicelluloses complex molecular structure makes it difficult to understand the relationship between structure and properties entirely, and their biological role is not yet fully verified. READ MORE

5. Recalcitrance of wood to biochemical conversion : feedstock properties, pretreatment, saccharification, and fermentability
Abstract : Lignocellulose is an inexpensive and abundant renewable resource that can be used to produce advanced biofuels, green chemicals, and other bio-based products. Pretreatment and efficient enzymatic saccharification are essential features of bioconversion of lignocellulosic biomass. READ MORE
