11. Techniques for Localization of Insulation Degradation along Medium-Voltage Power Cables
Sammanfattning : Time Domain Reflectometry (TDR) has been used for localization of transmission line discontinuities in diverse applications. Various challenges have to be addressed when applying TDR for localization of insulation degradation in power cables. LÄS MER
12. Fatigue Assessment of Container Ships – a Contribution to Direct Calculation Procedures
Sammanfattning : Within the field of marine structural engineering, the introduction of new materials and material classes, the development of production techniques and new design, and new requirements imposed by authorities are examples which justify a need for continuous revisit and update of fatigue assessment methodologies of marine structures. This thesis contributes to the development and improvement of fatigue assessment methodology for ship structures. LÄS MER
13. Fibre-Optic Displacement and Temperature Sensing Using Coupling Based Intensity Modulation and Polarisation Modulation Techniques
Sammanfattning : Optical fibre sensors are employed in the measurements of a number of different physical properties or for event detection in safety and security systems. In those environments which suffer from electromagnetic disturbance, in harsh environments where electronics cannot survive and in applications in favour of distributed detection, fibre-optic sensors have found natural areas of use.

14. Slab track optimisation considering dynamic train–track interaction
Sammanfattning : Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. LÄS MER
15. Time Domain Systems for Microwave Imaging: Accuracy Evaluations and Prototype Design
Sammanfattning : This thesis focuses on microwave hardware development for medical applications. In this thesis, we have evaluated the accuracy of time domain systems for medical imaging, and a time domain system dedicated to medical imaging has been designed, developed and tested. LÄS MER
