  1. 16. To analyse measurements is to know!

    Författare :Henrik Gadd; Institutionen för energivetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Hourly meter readings; fault detection; Low return temperature; temperature difference.;

    Sammanfattning : Renewable energy sources dominated the world energy supply until the beginning of the 20th century, when fossil energy became the dominant energy source worldwide. Today, fossil fuels contribute to over 80% of world energy supply. But there are two major reasons why fossil energy use has to stop. LÄS MER

  3. 17. Experimental design and vortex analyses in turbulent wake flows

    Författare :Bengt E. G. Fallenius; Jens H. M. Fransson; Henrik Alfredsson; Marianna Braza; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bluff bodies; wake flow; experimental design; vortex detection; flow control; asymptotic suction boundary layer;

    Sammanfattning : A new experimental setup for studies on wake flow instability and its control that successfully has been designed and manufactured, is introduced and de- scribed. The main body is a dual-sided flat plate with an elliptic leading edge and a blunt trailing edge. LÄS MER

  4. 18. Development and use of an optical pCO2 sensor in marine studies

    Författare :Dariia Atamanchuk; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pCO2; O2; sensor; optode; cross-sensitivity; carbonate system of seawater; biogeochemistry; Redfield ratio; the Koljo Fjord; cabled observatory; CCS; QICS; environmental engineering; leakage detection; MVDA; DoE;

    Sammanfattning : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. LÄS MER

  5. 19. A flexible resonance sensor system for detection of cancer tissue : evaluation on silicon

    Författare :Anders P. Åstrand; Britt Andersson; Ville Jalkanen; Olof A. Lindahl; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The most common form of cancer among men in Europe and the US is prostate cancer. When a radical prostatectomy has been found necessary, it is of interest to examine the prostate, as tumour tissue on the capsule might indicate that the cancer has metastased. This is commonly done by a microscope-based morphometric investigation. LÄS MER

  7. 20. Fault detection and model quality estimation using mixed integer linear programming

    Författare :Soheil Salehpour; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Robustness is a necessary property of a control system in an industrial environment, due to changes of the process such as changes of material quality, aging of equipment, replacing of instrument, manual operation (e.g. a valve that is opened or closed) etc. LÄS MER
