  2. 1. Perceptual Surface Reconstruction

    Author : Jens Månsson; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; system; kontroll; Psychology; Psykologi; numerisk analys; Datalogi; systems; control; numerical analysis; Surface; Contour; Depth; Vision; Binocular; Computer science;

    Abstract : How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theoretical and computational perspective, as well as through empirical investigations. In paper one, the fundamentals of stereopsis are briefly reviewed, and the difficulties related with resolving the (stereo) correspondence problem are particularly discussed. READ MORE

  4. 2. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants

    Author : Carin Hallgren Höstner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surface modification; surface texture; roughness; surface evaluation; in vivo studies.;

    Abstract : PurposeThe purpose of the present thesis was to investigate the bone response to different isotropic, anisotropic and organised surface patterns.Material and methodsImplant surfaces have been modified with different techniques (abrasive blasting, turning, milling, photolithography or laser ablation).

  5. 3. Fiber-Supported Hydrogels with Controlled surface Properties

    Author : Jan Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellulose; fiber; ozone; polypropylene; graft polymerization; hydrogel; surface;

    Abstract : Hydrogels are emerging materials that have the ability to hold a substantial amount of water. However, the low mechanical performance of hydrogels is often a limitation for extending the field of applications. READ MORE

  6. 4. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

    Author : Edwin Obando; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

    Abstract : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. READ MORE

  7. 5. Surface Plasmon Resonance : Sensitivity and Resolution

    Author : Knut Johansen; Günter Gauglitz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. READ MORE
