  2. 16. Implementation of digital-serial LDI/LDD allpass filters

    Author : Krister Landernäs; Johnny Öberg; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Elektronik;

    Abstract : In this thesis, digit-serial implementation of recursive digital filters is considered. The theories presented can be applied to any recursive digital filter, and in this thesis we study the lossless discrete integrator (LDI) allpass filter. READ MORE

  4. 17. 177Lu-DOTA-octreotate Radionuclide Therapy of Neuroendocrine Tumours : Dosimetry-Based Therapy Planning and Outcome

    Author : Ulrike Garske-Román; Barbro Eriksson; Anders Sundin; Jens Sörensen; Dik Kwekkeboom; Uppsala universitet; []
    Keywords : ;

    Abstract : Peptide receptor radionuclide therapy for the internal radiation of neuroendocrine tumours expressing somatostatin receptors has made great advances and offers promising results. 177Lu-DOTA-octreotate is one of the most widely used radiopeptides, but kidneys and bone marrow are organs at risk.

  5. 18. Very high cycle fatigue of automotive steels : Testing and computation at 20 kHz

    Author : Mohamed Sadek; Jens Bergström; Nils Hallbäck; Ulrich Krupp; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very high cycle fatigue; ultrasonic fatigue testing; automotive steels; fatigue strength; stress intensity computation; crack growth; Materialteknik; Materials Engineering;

    Abstract : Mechanical fatigue failure occurs in components subjected to cyclic loading. A crack initiates at critical regions in the component and propagates during repeated loading. The expected fatigue life depends on the level, type and frequency of the loading. READ MORE

  6. 19. Estimating inclusion content in high performance steels

    Author : Jens Ekengren; Jens Bergström; Christer Burman; Hans Nordberg; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Engineering; Materialteknik;

    Abstract : Non-metallic inclusions in steel pose a major problem for the fatigue resistance, especially regarding fatigue at very long lives corresponding to low cyclic stress levels, as well as being detrimental to material toughness and polishability.The largest inclusions are quite rare, which makes conventional detection methods timeconsuming if reliable results are to be obtained.

  7. 20. Probabilistic modeling of fatigue failures

    Author : Kristoffer Karlén; Mårten Olsson; Gary Marquis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Fatigue is a well known failure mode in engineering that can have catastrophic consequences, such as loss of human life. Thus design against fatigue failure is very important. There are many sources of scatter present in fatigue, for instance; the difference in load in-between users of a product, material scatter and scatter in the production. READ MORE
