   Sammanfattning : This thesis treats static and dynamic surface characterization using radiometric and Fourier optical methods. A Fourier optical method has been developed for real time image processing in paper production and printing applications. LÄS MER

3. 12. Virtual reality based kinematics for assessment of post-stroke upper limb function

   Författare :Netha Hussain; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; motion analysis; upper extremity; arm function; kinematics; virtual reality; outcome assessment; rehabilitation; recovery of function; task performance and analysis;

   Sammanfattning : The main scope of this thesis was to develop a method for assessing the upper limb sensorimotor function following stroke using virtual reality-based technique. The studies reported in this thesis included 67 individuals extracted from the SALGOT (Stroke Arm Longitudinal Study at the University of Gothenburg) cohort and 43 healthy controls. LÄS MER

4. 13. Oxide Formation and Degradation during Erosion-Corrosion of Iron and Nickel Based Alloys

   Författare :Rikard Norling; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AES; fluidised bed; FBC; XPS; erosion-corrosion; SO2; crack formation; surface analysis; HCl; enhanced oxidation;

   Sammanfattning : Erosion-corrosion is, in many technical applications, a serious material degradation process caused by dynamic particle/fluid mixtures. Pipes transporting particle containing liquids, jet engines, gas turbines, and fluidised bed combustion (FBC) power plants are examples of systems which are considered to be especially susceptible.

5. 14. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication

   Författare :Sarunas Petronis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofabrication; surface characterization; surface topography; surface chemical composition; marine biofouling; force-sensing substrates; microfabrication; surface-enhanced Raman spectroscopy; cell-surface interaction; biointerfaces; biomaterials;

   Sammanfattning : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. LÄS MER

7. 15. Novel boron compounds in lubrication

   Författare :Mamoun Taher; Mark Rutland; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : Lubricants are used to control friction and reduce wear by preventing direct contact between surfaces in a relative motion. Most of the modern lubricants and lubricant additives have been designed and optimized for ferrous materials. LÄS MER
