  2. 1. Applanation Resonance Tonometry for Intraocular Pressure Measurement

    Author : Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
    Keywords : Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

    Abstract : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. READ MORE

  4. 2. Multifunctional nanostructured Ti-Si-C thin films

    Author : Per Eklund; Lars Hultman; Hans Högberg; G. Ramanath; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : In this Thesis, I have investigated multifunctional nanostructured Ti-Si-C thin films synthesized by magnetron sputtering in the substrate-temperature range from room temperature to 900 °C. The studies cover high-temperature growth of Ti3SiC2 and Ti4SiC3, low-temperature growth of Ti-Si-C nanocomposites, and Ti-Si-C-based multi¬layers, as well as their electrical, mechanical, and thermal-stability properties.

  5. 3. Thin film growth and characterization of Ti-(Si,Ge)-C compounds

    Author : Per Eklund; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis describes growth by de magnetron sputtering of thin film Ti-Si-C and Ti-Ge-C materials, with an emphasis on the deposition conditions for nanocomposite and epitaxial growth at low and high temperature processing, respectively. In the Ti-Si-C materials system, I have synthesized nanocomposite thin films from a Ti3SiC2 compound target in an Ar discharge on Si(100), Al2O3(0001), and Al substrates at low substrate temperature (300 oC and below).

  6. 4. Corporate Governance, Private Property and Investment

    Author : Johan Eklund; Per-Olof Bjuggren; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : Corporations have become the dominant organizational form in modern market economies, managing vast resources. Corporations are however associated with a number of governance problems. This dissertation deals with these corporate governance issues from an investment perspective. READ MORE

  7. 5. Scalable Bayesian spatial analysis with Gaussian Markov random fields

    Author : Per Sidén; Mattias Villani; Anders Eklund; Håvard Rue; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial statistics; Bayesian statistics; Gaussian Markov random fields; fMRI; Machine learning; Spatial statistik; Bayesiansk statistik; Gaussiska Markov-fält; fMRI; Maskininlärning;

    Abstract : Accurate statistical analysis of spatial data is important in many applications. Failing to properly account for spatial autocorrelation may often lead to false conclusions. READ MORE
