  1. 1. Railway Track Stiffness Dynamic Measurements and Evaluation for Efficient Maintenance

    Detta är en avhandling från Stockholm : KTH

    Författare :Eric Berggren; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway track stiffness; maintenance; soil dynamics; measurement; simulation; vibration; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. LÄS MER

  3. 3. Strukturmekanik & arkitektur Om strukturmekanisk förståelse i gestaltningsprocessen

    Detta är en avhandling från Stockholm : KTH

    Författare :Karl-Gunnar Olsson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CALFEM; stiffness; structural mechanics; design; architecture; Architectural design process; pointSketch; ForcePAD; canonical stiffness; static eigenvalues;

    Sammanfattning : Organizing material to produce space and a load-carrying structure are central tasks in the architectural design process. In trying out and examining design ideas, use of language and tools appropriate to the purpose is fundamental. LÄS MER

  4. 4. Resonance sensor technology for detection of prostate cancer

    Detta är en avhandling från Umeå : Fysik

    Författare :Ville Jalkanen; Umeå universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resonance sensor; prostate tissue; stiffness; detecting prostate cancer; TECHNOLOGY Other technology Medical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Medicinsk teknik;

    Sammanfattning : Prostate cancer is the most common type of cancer in men in Europe and the USA. Some prostate tumours are regarded as stiffer than the surrounding normal tissue, and therefore it is of interest to be able to reliably measure prostate tissue stiffness. The methods presently used to detect prostate cancer are inexact, and new techniques are needed. LÄS MER

  5. 5. Tactile sensing of prostate cancer a resonance sensor method evaluated using human prostate tissue in vitro

    Detta är en avhandling från Umeå : Tillämpad fysik och elektronik

    Författare :Ville Jalkanen; Umeå universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tactile resonance sensor; prostate tissue; prostate cancer; stiffness; density; elastic; variations; tissue histology; TECHNOLOGY Other technology Medical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Medicinsk teknik;

    Sammanfattning : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. LÄS MER
