1. The short, excited life of tellurium : Lifetime analysis of excited states in the Te midshell region
Sammanfattning : In this licentiate thesis, lifetimes of low lying excited states in the midshell region of tellurium isotopes are discussed. The nuclear lifetimes are interesting properties to study, since they are inversely proportional to the transition probabilities, which contain information on the underlying structure of the nucleus.

2. Lifetime modeling and management of transformers
Sammanfattning : This work have studied and developed lifetime estimation methods for the power transformer and how these could be used for asset management purposes. It is researchperformed in the intersection of the fields of reliability theory, statistical analysis, and stochastic process theory applied to lifetime estimations and management of transformers.

3. An eyesafe, long lifetime, stimulated Raman scattering laser
Sammanfattning : .... LÄS MER
4. Condition measuring and lifetime modelling of electrical power transmission equipment
Sammanfattning : The electric grid is important in modern society, so the outages should be few. The transmission grid should have a real high availability, since it transports electrical energy across the country. Then, it is difficult to plan outages for maintenance and installation. LÄS MER
5. Lifetime Surface Phosphor Thermometry - Technique Developments, Sources of Error, and Applications
Sammanfattning : Temperature is not only a fundamental aspect of everyday life, but it is also an essential metric for thermal conversion systems concerning efficiency, emissions, and component lifetime estimation. Therefore, a vast range of different methods to measure temperature has been developed. LÄS MER
