  1. 11. Local variation in bending stiffness in structural timber of Norway spruce : for the purpose of strength grading

    Författare :Min Hu; Marie Johansson; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital image correlation; fibre angle; high resolution; laser scanning; local stiffness; MOE profile; mode shape curvature; strain field; strength grading; structural timber; tracheid effect; Digital image correlation; fibervinkel; laserskanning; lokal styvhet; MOE-profil; töjningsfält; hållfasthetssortering; konstruktionsvirke; trakeideffekt; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Most strength grading machines on the European market use an averagemodulus of elasticity (MOE), estimated on a relatively large distance along awood member, as the indicating property (IP) to bending strength. Theaccuracy of such grading machines in terms of coefficient of determination israther low at R2 ≈ 0.5. LÄS MER

  3. 12. Distance Functions and Their Use in Adaptive Mathematical Morphology

    Författare :Vladimir Ćurić; Gunilla Borgefors; Cris L. Luengo Hendriks; Hugues Talbot; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Distance functions; Mathematical morphology; Adaptive mathematical morphology; Image regularization; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : One of the main problems in image analysis is a comparison of different shapes in images. It is often desirable to determine the extent to which one shape differs from another. This is usually a difficult task because shapes vary in size, length, contrast, texture, orientation, etc. Shapes can be described using sets of points, crisp of fuzzy. LÄS MER

  4. 13. Logistics Organization Design for Building Contractors

    Författare :Petter Haglund; Martin Rudberg; Ahmet Anil Sezer; Jenny Bäckstrand; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Construction logistics management is crucial for timely and cost-effective project delivery. While studies highlight improved project performance with a strategic and long-term approach to construction logistics management, there is a tendency to pursue project-centric logistics planning, hindering long-term, strategic approaches.

  5. 14. Byggbranschens innovationsbenägenhet : En studie om den svenska byggbranschens inställning till innovationer och branschens beredskapatt hantera innovationsfrågor

    Författare :Sune Björklöf; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Building sector; Dissemination of innovation; Innovation; Qualitative method; Socio Cultural tradition; Technical innovation;

    Sammanfattning : The attitude of the building sector towards innovation and its intellectual and organizational preparedness for dealing with the issues of innovation is the aim of this study. The core question can be formulated as follows: Why does a building company accept certain innovations but not others? The fundamental ideas of the study are rooted in the central European tradition of the historico-qualitiative school of thought. LÄS MER

  7. 15. Multiphase continuum modeling of wood : A hybrid mixture theory approach

    Författare :Winston Mmari; Björn Johannesson; Lynn Schreyer; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Coupled heat and moisture; Over-hygroscopic; Hybrid mixture theory; Mixture theory; Swelling; Hygro-mechanical; Non-linear elasticity; Large deformation; Phase field crack model; Anisotropic cracking; FEM; Numerical model; Norway spruce; Wood; Porous media; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. LÄS MER
