  1. 1. Ocular counter-rolling during head tilt

    Författare :Tony Pansell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Eye movements; Ocular torsion; VOR; head tilt; Vision.;

    Sammanfattning : When tilting the head towards the shoulder there are numerous mechanisms influencing on the generation and maintenance of ocular counter-roll. Each of these mechanisms has its own temporal and spatial characteristics which influences on the counter-rolled eye position. LÄS MER

  4. 3. The subjective visual horizontal in the diagnosis of vestibular disorders : physiological and clinical considerations

    Författare :Arne Tribukait; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vestibular system; vestibular tests; vestibular neuritis; Meniere sdisease; gentamicin treatment; vestibular compensation; stapedotomy; spatial orientation; gravity otoliths; utricle; saccule; semicircular canals; subjective visual horizontal; roll;

    Sammanfattning : In the examination of patients with vestibular disturbances the diagnostic techniques are almost entirely focused on the semicircular canals. However, a considerable number of the patients have symptoms which are suggestive of an affection of the otolith organs, e.g. false sensations of tilt or linear motion and even sudden falls. LÄS MER

  5. 4. Haemodynamic management in liver surgery

    Författare :Lena Sand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; liver resection; nitroglycerine; central venous pressure; vasopressin; patient position; PEEP;

    Sammanfattning : Background: Liver resection surgery is a potentially curative treatment for liver tumours. The liver is a highly vascular organ, and substantial intra-operative blood loss is common. Increased blood loss negatively impacts both postoperative outcome and long-term survival. LÄS MER

  7. 5. Efficient Spatiotemporal Filtering and Modelling

    Författare :Jörgen Karlholm; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The thesis describes novel methods for efficient spatiotemporal filtering and modeling. A multiresolution algorithm for energy-based estimation and representation of local spatiotemporal structure by second order symmetric tensors is presented. The problem of how to properly process estimates with varying degree of reliability is addressed. LÄS MER
