  2. 1. Peripheral Vision : Adaptive Optics and Psychophysics

    Author : Robert Rosén; Peter Unsbo; Larry Thibos; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. READ MORE

    Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. First order aspects defining the main functions of a component are well known and new challenges appear at a lower scale. READ MORE

  5. 3. Nanostructured TiN/ZrAlN and HfAlN Thin Films : Effect of Structure on Mechanical Properties

    Author : Marcus Lorentzon; Naureen Ghafoor; Jens Birch; Johanna Rosén; Peter Hedström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Transition metal nitrides are a remarkable group of ceramic materials that offer exceptional properties such as high hardness, low tribological wear, excellent thermal stability, and high oxidation resistance. Alloys such as TiN, CrN, VN, ZrN, and HfN have been identified as ideal candidates for protective coatings on cutting tool inserts in the metal processing industry. READ MORE
