1. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance
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. Modelling Stiffness and Damping by Use of Fractional Calculus with Application to Railpads
Abstract : When studying the dynamic behaviour of a structure, e g a railway track, it is important for the analyst to model both stiffness and damping accurately. Mathematical models including fractional derivatives have been found to work well for many materials. Such models are linear and causal. READ MORE

4. Resonance sensor technology for detection of prostate cancer
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

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