1. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance
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
2. Dynamic track stiffness measurement : a new tool for condition monitoring of track substructure
Sammanfattning : .... LÄS MER
3. Strukturmekanik & arkitektur Om strukturmekanisk förståelse i gestaltningsprocessen
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. Modelling Stiffness and Damping by Use of Fractional Calculus with Application to Railpads
Sammanfattning : 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. LÄS MER
5. Resonance sensor technology for detection of prostate cancer
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
