1. Voltage Sags: Single event characterisation, system performance and source location
Sammanfattning : This thesis deals with one of the most important disturbances that affect the quality of the electrical supply. Voltage sags cause industrial processes malfunction, producing an enormous economical impact. A voltage sag is defined as a short duration reduction of the rms voltage. LÄS MER
2. Location and Relocation of Seismic Sources
Sammanfattning : This dissertation is a comprehensive summary of four papers on the development and application of new strategies for locating tremor and relocating events in earthquake catalogs.In the first paper, two new strategies for relocating events in a catalog are introduced. LÄS MER
3. Exploiting Sparse Structures in Source Localization and Tracking
Sammanfattning : This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. LÄS MER
4. Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods
Sammanfattning : Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. LÄS MER
5. Source localisation of epileptiform activity in epilepsy of temporal lobe origin
Sammanfattning : In patients with drug resistant partial epilepsy, who are under consideration for epilepsy surgery, interictal and ictal EEG recorded with extracranial electrodes plays an important role in the localisation of the seizure onset area. During the past years, methods have been developed, which can be used to estimate the location of the source of epileptiform activity in the brain from extracranial EEG data. LÄS MER
