  2. 1. Wood fingerprint recognition and detection of thin cracks

    Author : Tobias Pahlberg; Olle Hagman; Matthew Thurley; Michael Felsberg; Luleå tekniska universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

    Abstract : The first part of this thesis deals with recognition of wood fingerprints extracted from timber surfaces. It presents different methods to track sawn wood products through an industrial process using cameras. READ MORE

  4. 2. Studies on the competitiveness of wood : - market segmentation and customer need assessments

    Author : Ragnar Jonsson; Roger Cooper; Växjö universitet; []
    Keywords : wood; building material; material substitution; end-consumer; floorcovering; customer needs; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : Over the last decades, wood has encountered increasing competition from other building materials. Hence, it is relevant to study the underlying factors of material substitution. The market for repair and remodelling (R&R) is growing in importance. READ MORE

  5. 3. Compression mechanisms and strength properties of semi- isostatically densified wood

    Author : Jonas Blomberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology; Densified wood;

    Abstract : Since most strength properties increase with increased wood density, densifying wood through compression will increase strength and wear resistance. After densification, wood with originally low density can substitute denser wood and originally dense wood can be used for purposes where wood is considered too soft, e.g. READ MORE

  6. 4. Modelling and simulation in the early stages of the development process of a manufacturing system : a case study of the development process of a wood flooring industry

    Author : Jon Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Manufacturing Simulation, or more accurately, Discrete Event Simulation (DES), is an important problem-solving methodology for the solution of many real-world problems in the manufacturing industry. Implementation of DES has become successful in a number of industrial sectors. READ MORE

  7. 5. Quality Aspects of Sliced Oak Lamellae in Development of Engineered Wood Flooring

    Author : Victor Grubîi; Jimmy Johansson; Alexander Pfriem; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood slicing multi-layered flooring surface-checking climate test. hardwoods processing slicing lathe checks digital image correlation DIC image processing veneers; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Valuable hardwoods, such as oak, although renewable, present limitations in product realisation in terms of their cost and availability, often attributed to production waste and sub-optimal product design factors. The slicing technique facilitates the production of thin wood lamellae, minimising waste and ensuring optimal material conversion. READ MORE
