16. New innovative methods for non-intrusive optical diagnostics of high-voltage insulator materials
Sammanfattning : The purpose of this PhD thesis work has been to develop optical techniques that can help utility engineers for assessing the state of insulators in service and in a laboratory. The possibilities to use remote laser induced fluorescence for detection and imaging of biological growth such as algae and fungi have been investigated. LÄS MER
17. The drumlin problem : streamlined subglacial bedforms in southern Sweden
Sammanfattning : This thesis investigates stream-lined subglacial bedforms (often referred to as drumlins) in southern Sweden. The broad aim of this is to contribute to the solution of the ‘drumlin problem’. The term drumlin has come to be applied to a wide range of features whose internal architecture (core) and overall morphology are seen to vary greatly. LÄS MER
18. Enablement of digital twins for railway overhead catenary system
Sammanfattning : Railway has the potential to become one of the most sustainable mediums for passenger and freight transport. This is possible by continuous updates to the asset management regime supporting Prognostics and Health Management (PHM). Railway tracks and catenaries are linear assets, and their length plays a vital role in maintenance. LÄS MER
19. Aeolian dunes of central Sweden
Sammanfattning : In the Swedish inland there are aeolian deposits present, ranging from scattered single dunes to dune fields of more than 10 km2. These dune fields often pass unnoticed since they presently are covered by vegetation. However, they contain a rich palaeoenvironmental archive. LÄS MER
20. Aspects of Optical Broad Band Spectroscopy and Information Extraction - Applications in Medicine and Ecology
Sammanfattning : The present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. LÄS MER
