  1. 11. Application of monitoring to dynamic characterization and damage detection in bridges

    Författare :Ignacio Gonzalez; Raid Karoumi; Eugene O'Brien; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural health monitoring; Traffic monitoring; Bridge monitoring; Bridge Weigh-In-Motion; BWIM; Damage detection; Suspension bridge bearings; Axle loads; Dynamics; Temperature effect;

    Sammanfattning : The field of bridge monitoring is one of rapid development. Advances in sensor technologies, in data communication and processing algorithms all affect the possibilities of Structural Monitoring in Bridges. LÄS MER

  3. 12. Statistical Fault Detection with Applications to IMU Disturbances

    Författare :David Törnqvist; Fredrik Gustafsson; Alexander Medvedev; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Linear systems; State-space models; Signal processing; State estimation; Fault observability; Inertial Measurement Unit; Automatic control; Reglerteknik;

    Sammanfattning : This thesis deals with the problem of detecting faults in an environment where the measurements are affected by additive noise. To do this, a residual sensitive to faults is derived and statistical methods are used to distinguish faults from noise. LÄS MER

  4. 13. Gait Event Detection in the Real World

    Författare :Siddhartha Khandelwal; Nicholas Wickström; Thorsteinn Rögnvaldsson; Brian Caulfield; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gait analysis; gait event detection; wearable sensors; accelerometers;

    Sammanfattning : Healthy gait requires a balance between various neuro-physiological systems and is considered an important indicator of a subject's physical and cognitive health status. As such, health-related applications would immensely benefit by performing long-term or continuous monitoring of subjects' gait in their natural environment and everyday lives. LÄS MER

  5. 14. Sar Remote Sensing of Sea Ice: Towards automatic extraction of geophysical information

    Författare :Yan Sun; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification; deformation; SAR; segmentation; cross-correlation; rotation; optical flow; motion detection;

    Sammanfattning : Synthetic Aperture Radar (SAR) images from the ERS-1 satellite have great potential for sea ice remote sensing due to its independence of daylight and clouds. The very high data rate of SAR (over 100 million bits per second) results in an enormous volume of data that threatens the ability of human interpreters. LÄS MER

  7. 15. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Författare :Aravin Chakravarthi; Funktionell zoologi; []
    Nyckelord :Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Sammanfattning : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. LÄS MER
