  2. 1. Design and Analysis of Diagnosis Systems Using Structural Methods

    Author : Mattias Krysander; Mattias Nyberg; Jan Lunze; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diagnosis; graph theory; structual methods; algorithms; fault isolation; complete; sound; Systems engineering; Systemteknik;

    Abstract : 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. READ MORE

  4. 2. Methods for Automated Design of Fault Detection and Isolation Systems with Automotive Applications

    Author : Carl Svärd; Mattias Nyberg; Erik Frisk; Mattias Krysander; Vincent Cocquempot; Linköpings universitet; []
    Keywords : ;

    Abstract : 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.

  5. 3. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications

    Author : Mattias Nyberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  6. 4. On Modeling and Diagnosis of Friction and Wear in Industrial Robots

    Author : André Carvalho Bittencourt; Svante Gunnarsson; Mattias Nyberg; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

  7. 5. Collectivity in Neutron-Rich Erbium Isotopes

    Author : Aila Gengelbach; Johan Nyberg; Lantz Mattias; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear structure; collective excitations; rare-earth nuclei; gamma-ray spectroscopy; AGATA; PRISMA; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : 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. READ MORE
