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.

3. On the small strain stiffness of some Scandinavian clays and impact on deep excavation
Abstract : This thesis presents the results of a comprehensive study on the small strain stiffness of several Swedish clays and its tentative effect on the design of retaining structures. A combination of field measurement techniques, seismic dilatometer and surface seismics, are complemented with bender element testing of the retrieved samples. READ MORE

4. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production
Abstract : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). READ MORE
