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

    University dissertation from Stockholm : KTH

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

    Abstract : 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. READ MORE

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

    University dissertation from Umeå : Fysik

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

    Abstract : 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. READ MORE

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

    University dissertation from Umeå : Tillämpad fysik och elektronik

    Author : Ville Jalkanen; Umeå universitet.; [2007]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    University dissertation from Stockholm : Farkost och flyg

    Author : Hans Kolsters; KTH.; [2004]
    Keywords : Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Abstract : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.
