  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

  5. 3. Theoretical modelling of LA-MRSA in Swedish pig production

    Author : Krista Tuominen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Antimicrobial resistance is a threat to global health. Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) is a category of multiresistant bacteria that primarily colonises livestock animals. While pigs are considered its main reservoir, LA-MRSA is zoonotic and causes an occupational risk to those working with livestock. READ MORE

    Abstract : The organisation of fluids in small compartments is ubiquitous in nature, such as in the cellular composition of all life. This work explores several engineering avenues where microscale fluid compartmentalization can bring novel material properties or novel functionality in life sciences or medicine. READ MORE

  7. 5. Graphene: Applications in Surface Science Studies

    Author : Virginia Boix; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Surface Science; EBID; Catalysis; undercover catalysis; XPS; APXPS; STM;

    Abstract : This thesis addresses how graphene can be a valuable asset for surface science studies. Using a combination of X- ray photoelectron spectroscopy, scanning tunneling microscopy, and low-energy electron diffraction, we take advantage of graphene’s sensitivity to changes in its chemical environment to obtain an atomic scale understanding of different reactions occurring above and below the film.
