  4. 17. Condition Monitoring of Water Contamination in Lubricating Grease for Tribological Contacts

    Author : Nicholas J. Dittes; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : The purpose of this thesis is to summarize the research carried out that led to the development of measurement techniques which measure the water content of lubricating grease. A simple and effective grease mixing method for preparing grease samples was developed and tested for repeatability. READ MORE

  5. 18. Statistical tools for ultrasonic analysis of dispersive fluids

    Author : Jesper Martinsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis focuses on the possibility of using ultrasonic measurement techniques for energy gas characterization. The idea is to combine both on-line flow measurements with non-invasive fluid characterization in the same measurement setup using the same sensor(s). READ MORE

  6. 19. Sensors for Water Contamination in Lubricating Grease

    Author : Nicholas Dittes; Mikael Sjödahl; Robert Dwyer-Joyce; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Abstract : The purpose of this dissertation is to summarize the research carried out that led to the development of measurement techniques which measure the water content of lubricating grease. Calcium sulphonate complex (CaS-X) grease was used in all experiments for Papers A through E, with some additional greases used in Paper D. READ MORE

  7. 20. Measuring and modelling light scattering in paper

    Author : Niklas Johansson; Per Edström; Mattias Andersson; Magnus Neuman; Jon Yngve Hardeberg; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; goniophotometry; anisotropy; angle resolved light scattering; reflectance measurements; turbid media;

    Abstract : Avhandlingen behandlar de teoretiska och praktiska aspekterna av att använda spektrala vinkelupplösta reflektansmätningar för optisk karakterisering av fiberbaserade material såsom papper och kartong. En spektral goniofotometer används för att mäta det reflekterade ljusets vinkelfördelning. READ MORE
