2. Time and Frequency Domain Measurement Methods for High Frequency Characterisation of Power Cables
Abstract : Time Domain Reflectometry (TDR) has been used forlocalisation of transmission line discontinuities in variousapplications. One of the challenges when applying TDR on powercables is to obtain knowledge of the high frequencycharacteristics of both the degraded and the undegradedsections of the cable. READ MORE

4. An FRA Transformer Model with Application on Time Domain Reflectometry
Abstract : Frequency response analysis (FRA) is a frequency-domain method which is used to detect mechanical faults in transformers. The frequency response of a transformer is determined by its geometry and material properties, and it can be considered as the transformer’s fingerprint. READ MORE

5. Brownian Relaxation Measurements of Magnetic Nanoparticles: Towards the Development of a Novel Biosensor System
Abstract : Magnetic measurements of the Brownian relaxation time of thermally blocked magnetic nanoparticles dispersed in a solution have been performed in order to determine the hydrodynamic size distribution of the particles. By measuring changes in the hydrodynamic size of the particles, the ammount of analytes attached to the surface of particles can be determined. READ MORE
