1. 11. On-line vectorcardiography in ischemic heart disease

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

   Sammanfattning : 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.

4. 13. A Study of Different Methods for Inclusion Characterization towards On-line use during Steelmaking

   Författare :Diana Janis; Pär Jönsson; Lauri Holappa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; on-line method; PDA OES; electrolytic extraction; inclusions; clusters; nozzle clogging; secondary steelmaking;

   Sammanfattning : The interest of gaining on-line information related to non-metallic inclusions during the steelmaking process has recently increased due to the development as well as the promising results of the Pulse Distribution Analysis with Optical Emission Spectroscopy method (PDA/OES). Even though, the time from sampling to presented results on inclusions is only about 5-10 minutes, the method has also shown limitations with respect to the determination of some inclusion characteristics.

5. 14. Modeling and on-line optimization of cone crushers

   Författare :Khalid Atta; Matti Vilkko; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This licentiate thesis deals with the Modeling, Control, and On-line optimization of Cone Crushers. Cone crushers are used for size reduction of minerals and are considered as a central element in many mineral processing plants. LÄS MER

7. 15. On-Line Monitoring Applications in Nuclear Power Plants

   Författare :Hashem Mehrdad Hashemian; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calibration monitoring; noise analysis; instrumentation and control; sensing line blockages; Nuclear power plants; sensor response time testing; reactor diagnostics; next generation reactors; applied research;

   Sammanfattning : As the current generation of nuclear power plants have passed their mid-life, increased monitoring of their health is critical to their safe operation. This is especially true now that license renewal of nuclear power plants has accelerated, allowing some plants to operate up to 60 years or more. LÄS MER
