  2. 6. New Experimental and Modelling Tools for Multiscale Characterization of Asphalt Mastic

    Author : Hassan Fadil; Denis Jelagin; Robert Ingemar Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building Materials; Byggnadsmaterial;

    Abstract : Asphalt mastics act as a binding phase in asphalt mixtures and their rheological properties strongly affect the performance of asphalt mixtures with respect to virtually all damage modes. In order to measure mastics properties, relevant for field performance, testing should be performed at size-scales representative for the morphology and material inhomogeneity of asphalt mixtures.

  4. 7. A Tactile Resonance Sensor System for Detection of Prostate Cancer ex vivo : Design and Evaluation on Tissue Models and Human Prostate

    Author : Anders P Åstrand; Britt M Andersson; Ville Jalkanen; Olof A Lindahl; E. Göran Salerud; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; elektronik;

    Abstract : Background The most common form of cancer among males in Europe and the USA is prostate cancer, PCa. Surgical removal of the prostate is the most common form of curative treatment. READ MORE

  5. 8. A flexible resonance sensor system for detection of cancer tissue : evaluation on silicon

    Author : Anders P. Åstrand; Britt Andersson; Ville Jalkanen; Olof A. Lindahl; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The most common form of cancer among men in Europe and the US is prostate cancer. When a radical prostatectomy has been found necessary, it is of interest to examine the prostate, as tumour tissue on the capsule might indicate that the cancer has metastased. This is commonly done by a microscope-based morphometric investigation. READ MORE

  6. 9. Grinding effects on surface integrity, flexural strength and contact damage resistance of coated hardmetals

    Author : Jing Yang; Magnus Odén; Luis Llanes; Andrew Gant; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The tribological and mechanical behavior of coated tools depends not only on intrinsic properties of the deposited film but also on substrate surface and subsurface properties – such as topography and residual stress state – as well as on interface adhesion strength. It is particularly true in the case of coated tools based on WC-Co cemented carbides (backbone materials of the tool manufacturing industry, and simply referred to as hardmetals in practice) as substrates.

  7. 10. Determination of residual stresses and mechanical properties using neutron, X-ray diffraction, micro- and nanoindentation techniques

    Author : Cecilia Larsson; Richard Warren; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The existence of residual stresses in engineering materials can significantly affect subsequent lifetime by augmenting or impeding failure. Consequently, for an accurate assessment of engineering lifetimes, there is a need to quantify residual stresses. READ MORE
