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. Appearance grading of sawn timber
Abstract : Grading of sawn timber has by tradition been performed by manual ocular inspection of the wood surfaces. Even today, most wood produced is graded by manual inspection. READ MORE

4. Microwave sensors for scanning of sawn timber
Abstract : A microwave imaging sensor that measures the signal transmitted through a board was investigated with respect to the ability to predict the distribution of moisture and density in sawn lumber. Furthermore, the response from the sensor was related to strength properties of the boards. READ MORE

5. Numerical Analysis of Moisture-Related Distortion in Sawn Timber
Abstract : A 3D theory for the numerical simulation of deformations and stresses in wood during moisture variation is described. The constitutive model employed assumes the total strain rate to be the sum of the elastic strain rate, the moisture-induced strain rate, the mechano-sorption strain rate and the creep strain rate.
