  1. 1. On perfusion estimation using ultrasound

    Författare :Tomas Jansson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; Speckle; Artifacts; Perfusion; Ultrasound; Doppler; Mät- och instrumenteringsteknik;

    Sammanfattning : This thesis has the main focus on ways to improve the blood perfusion estimate, as obtained from a continuous wave Doppler system. Earlier studies have shown large temporal variations in the detected perfusion estimate, due to speckle. LÄS MER

    Sammanfattning : Koldioxid är en central parameter för metabolismen i alla levande varelser. Hos människan regleras koldioxidhalten främst genom andningen. Därför är det viktigt att kunna mäta och övervaka koldioxidhalten i fysiologiska applikationer så väl inom sportmedicin som inom vården, till exempel på intensivvårdsavdelningar. LÄS MER

  5. 4. Shaping thought through action : A study of the use and design of technical information

    Författare :Jonatan Lundin; Yvonne Eriksson; Carina Söderlund; Inger Orre; Harald Schaub; Mälardalens högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; Innovation and Design; innovation och design;

    Sammanfattning : This dissertation deals with the design of technical information, such as a user manual for an industrial device, based on the searching and reading behaviour of process operators and maintenance technicians. Such industrial professionals, who use tools like measuring equipment, are sometimes unable to get the support they need from searching and reading in a text- and image-based tool manual in order to perform work tasks.

    Sammanfattning : Truck transport offers a versatile way to ship goods in regional, long haulage and urban applications. However, the heavy truck sector accounts for 6 % of total greenhouse gas emissions in the European Union. Therefore, there is a need for a substantial reduction of these emissions to secure the sustainability of Earth for future generations. LÄS MER
