1. Design and Analysis of Diagnosis Systems Using Structural Methods
Sammanfattning : In complex and automated technological processes the effects of a fault can quickly propagate and lead to degradation of process performance or even worse to a catastrophic failure. This means that faults have to be found as quickly as possible and decisions have to be made to stop the propagation of their effects and to minimize process performance degradation. LÄS MER
2. Methods for Automated Design of Fault Detection and Isolation Systems with Automotive Applications
Sammanfattning : Fault detection and isolation (FDI) is essential for dependability of complex technical systems. One important application area is automotive systems, where precise and robust FDI is necessary in order to maintain low exhaust emissions, high vehicle up-time, high vehicle safety, and efficent repair.

3. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications
Sammanfattning : Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system. To develop a general theory for this, useful in real applications, is the topic of the first part of this thesis. LÄS MER
4. On Modeling and Diagnosis of Friction and Wear in Industrial Robots
Sammanfattning : Industrial robots are designed to endure several years of uninterrupted operation and therefore are very reliable. However, no amount of design effort can prevent deterioration over time, and equipments will eventually fail. Its impacts can, nevertheless, be considerably reduced if good maintenance/service practices are performed. LÄS MER
5. Collectivity in Neutron-Rich Erbium Isotopes
Sammanfattning : Neutron-rich rare-earth nuclei around the maximum of collectivity are predicted to exist with an extremely stable intrinsic configuration in their ground-state structure. Due to the high degree of axial symmetry and large deformation, these nuclei are also excellent candidates for having long-lived high-K isomers. LÄS MER
