  1. 1. Lung and chest wall properties during mechanical ventilation

    Författare :Per Erik Persson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Respiratory mechanics; Esophageal pressure; Positive end-expiratory pressure;

    Sammanfattning : Background: Mechanical ventilation causes injury to the lungs due to high pressures and high volumes. Pressure affecting the lungs, the transpulmonary pressure, needs to be monitored to minimise harmful side effects but then lung and chest wall mechanics need to be separately considered. LÄS MER

  3. 2. Heterotopic Ossification : Clinical and Experimental Studies on Risk Factors, Etiology and Inhibition by Non-steroidal Anti-inflammatory Drugs

    Författare :Per-Erik Persson; Olle Nilsson; Per Aspenberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Heterotopic ossification; Hip prosthesis; NSAIDs; Prophylaxis; Prosthesis loosening; Reoperation; Animal model; Bone formation; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : In this thesis, occurrence of heterotopic ossification (HO) following total hip arthroplasty (THA) was studied. Preventive effects and complications with non-steroidal anti-inflammatory drugs (NSAIDs) were analyzed. Experimental investigations on bone formation were employed to gain insight to the mechanism of NSAIDs action on bone.(I). LÄS MER

  4. 3. Visual Odometryin Principle and Practice

    Författare :Mikael Persson; Michael Felsberg; Klas Nordberg; Per-Erik Forssén; Janne Heikkilä; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Visual Odometry; Continuous Pose Trajectory; P3P; PNP; VO; Tracking; Calibration;

    Sammanfattning : Vision is the primary means by which we know where we are, what is nearby, and how we are moving. The corresponding computer-vision task is the simultaneous mapping of the surroundings and the localization of the camera. This goes by many names of which this thesis uses Visual Odometry. LÄS MER
