  1. 6. Beyond IT and Productivity : Effects of Digitized Information Flows in Health Care

    Författare :Pontus Fryk; Thomas Falk; Nils-Göran Olve; Mats Edenius; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Health Care; Productivity Paradox; Information Technology; Productivity; Process; Information; Communication; Economy; Business and economics; Ekonomi; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : Denna avhandling undersöker hur investeringar i IT, och digitaliseringen av informationsflöden, har påverkat produktiviteten inom sjukvården. Genom empiriska undersökningar av avgränsade sjukvårdsprocesser – samt diskussioner baserade på idéer och teorier relaterade till ekonomi, ”produktivitetsparadoxen”, så kallade General Purpose Technologies (GPTs), och medicinsk informatik – detekteras och analyseras effekter av digitaliseringen.

  3. 7. Travelling through time : Students’ interpretation of evolutionary time in dynamic visualizations

    Författare :Jörgen Stenlund; Lena Tibell; Konrad Schönborn; Niklas Gericke; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolution; visualization; time; learning; threshold; zooming;

    Sammanfattning : Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. LÄS MER

  4. 8. Perceptually motivated speech recognition and mispronunciation detection

    Författare :Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

    Sammanfattning : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. LÄS MER

  5. 9. Informationsdesign i tillståndsövervakning : En studie av ett bildskärmsbaserat användargränssnitt för tillståndsövervakning och tillståndsbaserat underhåll

    Författare :Carina Andersson; Yvonne Eriksson; Björn Fagerström; Karin Wagner; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; information design; user interface design; visual communication; människa-datorinteraktion; informationsdesign; gränssnittsdesign; visuell kommunikation; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Image analysis; Bildanalys; Innovation and Design; innovation och design;

    Sammanfattning : This research concerns the information design and visual design of graphical user interfaces (GUI) in the condition monitoring and condition-based maintenance (CBM) of production equipment. It also concerns various communicative aspects of a GUI, which is used to monitor the condition of assets. LÄS MER
