  1. 11. Game-calibrated and user-tailored remote detection of emotions : A non-intrusive, multifactorial camera-based approach for detecting stress and boredom of players in games

    Författare :Fernando Bevilacqua; Henrik Engström; Per Backlund; Vittorio Scarano; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; computer vision; non-obtrusive; remote sensing; affective computing; games; rPPG; Interaction Lab ILAB ; Interaction Lab ILAB ;

    Sammanfattning : Questionnaires and physiological measurements are the most common approach used to obtain data for emotion estimation in the field of human-computer interaction (HCI) and games research. Both approaches interfere with the natural behavior of users. LÄS MER

  3. 12. Driving in Virtual Reality : Investigations in Effects of Latency and Level of Virtuality

    Författare :Björn Blissing; Johan Ölvander; Fredrik Bruzelius; Henrik Engström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Virtual Reality; Augmented Reality; Mixed Reality; Latency; Driver Behavior; Active Safety Testing;

    Sammanfattning : When developing new active safety systems or improving existing systems, conducting performance evaluations is necessary. By performing these evaluations during early development stages, potential problems can be identified and mitigated before the system moves into the production phase. LÄS MER

  4. 13. Cerebrovascular accidents associated with aortic manipulation during cardiac surgery

    Författare :Patrik Boivie; Gunnar Engström; Magnus Hansson; Henrik Ahn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic atherosclerosis; aortic cannulation; aortic cross-clamp; cardiac surgery; cerebral protection; cerebrovascular accidents; epiaortic ultrasound; intra-aortic filter; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Sammanfattning : Background: Despite the successful development in cardiac surgery, cerebrovascular accidents (CVA) remain a devastating complication. Aortic atherosclerosis has been identified as a major risk factor for CVA. LÄS MER

  5. 14. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

    Författare :Carolina Samuelsson; Elisabeth Ronne-Engström; Lars Hillered; Eva Kumlien; Carl-Henrik Nordström; Uppsala universitet; []
    Nyckelord :Neurosciences; glutamate; glutamine; lactate; pyruvate; microdialysis; GLT-1; energy metabolism; intracranial pressure; cerebral perfusion pressure; subarachnoid hemorrhage; ischemia; epilepsy; Neurovetenskap;

    Sammanfattning : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. LÄS MER

  7. 15. Delirium after cardiac surgery : risk factors, assessment methods and costs

    Författare :Nina Smulter; Karl Gunnar Engström; Birgitta Olofsson; Micael Appelblad; Staffan Svenmarker; Henrik Bjursten; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac surgery; Cardiopulmonary bypass; Consequences; Delirium; Detection; Documentation; Economical aspect; Hospitalisation; Risk factors; Screening scales; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : Background: Cardiac surgery is considered safe, but postoperative delirium (POD) remains frequently reported. Delirium is characterised by fluctuations in consciousness and cognition, and can be subdivided into disturbed psychomotoric activity (hyperactive and hypoactive) and psychiatric symptom profiles (psychotic and emotional).
