  1. 11. Modelling the aerodynamics of iron ore pelletizing kilns

    Författare :Reine Granström; Christian Fredriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : In an iron ore pelletizing plant, crude ore is upgraded to pellets to be used as feedstock in steel-making plants. As part of a grate-kiln pelletizing plant, the rotary kiln is an indurating furnace in which the pellets are sintered. LÄS MER

  3. 12. Critical design activities in house-building projects : an industrial process perspective

    Författare :Martin Haller; Marcus Sandberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Dealing with planning accuracy respectively design errors is a big issue within construction. It has been argued that design errors are a major cause for waste in housing projects, despite all technical development. Reasons for design errors are well investigated and often relate to human acting. LÄS MER

  4. 13. Transparency for future semi-automated systems : effects of transparency on operator performance, workload and trust

    Författare :Tove Helldin; Göran Falkman; Maria Riveiro; Amy Loutfi; Lars Niklasson; Peter Svenmarck; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; semi-automation; trust; system transparency; meta-information; information fusion; semiautomation; tillit; systemtransparens; meta-information; informationsfusion; Datavetenskap; Computer Science; Technology; Skövde Artificial Intelligence Lab SAIL ;

    Sammanfattning : More and more complex semi-automated systems are being developed, aiding human operators to collect and analyze data and information and even to recommend decisions and act upon these. The goal of such development is often to support the operators make better decisions faster, while at the same time decrease their workload. LÄS MER

  5. 14. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis

    Författare :Madelene Holmgren; Anders Eklund; Jan Malm; Anders Wåhlin; Sara Qvarlander; Ronnie Wirestam; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 4D flow MRI; carotid stenosis; cerebral blood flow; cerebral arterial compliance; cerebrovascular resistance; circleof Willis; computational fluid dynamics; magnetic resonance imaging; stroke; vascular disease; Neurology; neurologi;

    Sammanfattning : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. LÄS MER

  7. 15. Configuration of modularised building systems

    Författare :Patrik Jensen; Miklos Molnar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Swedish building industry is mainly project-oriented where the design process is sequential involving various disciplines separated both in time and space. During the last decades the industry has been criticised and accused of having problems with quality and low productivity. LÄS MER
