  2. 1. Computational methods for on-line shape inspection

    Author : Per Bergström; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Abstract : This licentiate thesis describes computational methods that solve problems occurring in industrial on-line shape quality inspection of produced items. These items are measured and compared with their corresponding CAD object. The meaning of on-line is that the inspection is done on-line in the production line, i.e. READ MORE

  4. 2. On-line Mobile in situ Gamma Spectrometry

    Author : Thomas Hjerpe; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Kärnfysik; Nuclear physics; radiation protection.; 137Cs; peak-to-valley method; depth distribution; orphan source search; orphan sources; emergency preparedness; mobile gamma spectrometry; nuclear accidents; Nuclear medicine; radiobiology; Nukleärmedicin;

    Abstract : Mobile in situ gamma spectrometry is an important instrument in the emergency preparedness for nuclear accidents. This work contributes through the development of strategies and analysis methods for two applications: an on-line search for gamma-emitting orphan sources and on-line estimation of the depth distribution of 137Cs.

  5. 3. On-line vectorcardiography in ischemic heart disease

    Author : Peter Lundin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Vectorcardiography; ischemia monitoring; coronary artery disease; exercise test; echocardiography; dobutamine; unstable angina pectoris; myocardial infarction; prognosis.;

    Abstract : The clinical usefulness of continuous on-line vector cardiography (VCG) was assessed in 435 patients, admitted to the coronary care unit. The ability of 24-hour VCG monitoring to differentiate patients with or without ischemic heart disease (IHD), to provide long-term prognostic information and to predict results from a predischarge exercise test in patients with unstable angina pectoris or acute myocardial infarction (MI) was evaluated.

  6. 4. Partial Discharges in Large Rotating Machines - Continuous On-line Monitoring and Localisation, Based on a New Developed Technique (InTech)

    Author : Abkar Kheirmand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; InTech; detection; on-line monitoring; insulation; stator; condition control; PD measurement; Powerformer; winding; rotating machine; partial discharge;

    Abstract : Partial discharges (PD) that originate from dielectrically defective parts of the insulation system result in its degradation, which may ultimately lead to a failure of high voltage apparatus. This has resulted in development of numerous PD measuring techniques. One of the most widespread applications of PD measurement is in rotating machines. READ MORE
