  1. 21. Continuous monitoring of mineral processes with special focus on tumbling mills : a multivariate approach

    Författare :Kent Tano; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Increasing emphasis on productivity and quality control has provided an impetus to research on better methodologies for diagnosis, modelling, monitoring, control and optimisation of mineral process systems. One of the biggest challenges facing the research community is the processing of raw sensor data into meaningful information. LÄS MER

  3. 22. The role of leptin in endothelial dysfunction and cardiovascular disease

    Författare :Manuel Cruz Gonzalez Garcia; Stefan Söderberg; Jan Engvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; leptin; obesity; endothelial dysfunction; cardiovascular disease; kardiologi; Cardiology;

    Sammanfattning : Objective:  Obesity has become the leading cause of mortality worldwide; however, the fundamental pathophysiology underlying this association remains unclear. The discovery of adipokines, i.e., cytokines produced by adipose cells (adipocytes), revealed that adipose tissue is a highly endocrine organ, thus opening new lines of investigation. LÄS MER

  4. 23. Utmattningsanalys av järnvägsbroar : En fallstudie av stålbroarna mellan Stockholm Central och Söder Mälarstrand, baserat på teoretiska analyser och töjningsmätningar

    Författare :Andreas Andersson; Håkan Sundquist; Kjell Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Palmgren-Miners cumulative damage theory; Rainflow-analysis; railway bridges; finite element methods; Utmattning; Palmgren-Miners delskadehypotes; Rainflow-analys; järnvägsbroar; finita element metoder; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Föreliggande avhandling omfattar en fallstudie av utmattningsrisken för järnvägsbroarna mellan Stockholm Central och Söder Mälarstrand. Ett stort antal utmattningssprickor i broarna över Söderström och Söder Mälarstrand har sedan länge varit kända. LÄS MER

  5. 24. Controlling Forced Response of a High Pressure Turbine Blade

    Författare :Jeff Green; Torsten Fransson; Robert Kielb; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Vibration induced High Cycle Fatigue (HCF) is a major consideration in designing gas turbines. Indeed, the Gas Turbine manufacturer must demonstrate that the vibration level of the turbomachinery blading is acceptably low, usually by using an engine strain gauge test. LÄS MER

  7. 25. Coining Residual Stresses in Aluminium Ship Structures: Experiments and FE- simulations

    Författare :Rutger Ogeman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The build-up and redistribution of residual stresses obtained by stress coining of aluminium plates containing a hole have been studied experimentally and numerically. The foil strain gauge technique has been employed to measure strains at the bore of a hole during and after the coining process. LÄS MER
