  2. 16. Innovation Diffusion in the Construction Sector

    Author : Kristian Widén; Bengt Hansson; Marcela Miozzo; Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anläggningsteknik; Construction technology; Industriell ekonomi; Commercial and industrial economics; Construction Sector; Innovation; Diffusion; Anläggningsteknik; Construction technology; Industriell ekonomi; Commercial and industrial economics; Construction Sector; Innovation; Diffusion;

    Abstract : Innovation and development are the backbone of a thriving market economy. It is through innovations of various kinds that nations, industries and companies compete. Many actions in areas internationally and nationally will affect the construction sector. Research into construction innovation has attracted increasing interest. READ MORE

  4. 17. Small Molecule Diffusion in Spherulitic Polyethylene : Experimental Results and Simulations

    Author : Alessandro Mattozzi; Ulf W. Gedde; Alan H. Windle; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; polyethylene; poly ethylene-co-octene ; free volume; morphology; intermediate phase; spherulite; Monte Carlo simulation; Polymer chemistry; Polymerkemi;

    Abstract : The diffusion of small-molecule penetrants in polyethylene is hindered by impenetrable crystals and by the segmental constraints imposed by the crystals on the penetrable phase. Liquid and vapour n-hexane sorption/desorption measurements were performed on metallocene catalyzed homogenous poly(ethylene-co-octene)s. READ MORE

  6. 19. On the determination of diffusion coefficients in bone

    Author : Abdallah Shokry; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; Mathematical model; Spatially dependent diffusion; Diffusion in bone; Diffusion coefficient; Conductivity; Elastic modulus; Porous materials;

    Abstract : Diffusion in bone is needed for bone remodeling and bone healing. Understanding the phenomenon is often important for comprehension bone diseases. Mathematical modeling of the diffusion processes is a required prerequisite in the study of this important physical process in living bone tissue. READ MORE

  7. 20. Heterogeneous Materials - Diffusion, Laplace spectrum and NMR

    Author : Matias Nordin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; perturbation; nmr; diffusion; laplace operator; spectrum; heterogeneous materials;

    Abstract : Relations to the effective diffusion constant and the relaxation rate of the time-dependent diffusion coefficient for porous systems are derived from the Laplace operator spectrum. The Padé approximation is then explained in terms of the Laplace operator spectrum. READ MORE
