3D Speckle-Tracking: Sub-voxel Techniques and Tracking Accuracy
(Master thesis, 2006)Speckle tracking is a method that is useful for examining myocardial function. The method allows the cardiologist examine the left ventricular wall function when there are indications of a myocardial infarction. The method ... -
A One-Sensor System for Home Diagnosis and Therapy of Snoring and Sleep Apnea
(Master thesis, 2007)The average sleeping time suffers from a more and more stressful life, and is now close to the limit of what the human being can bear. Therefore, a good quality sleep is more important than ever. At the same time, the ... -
Adaptive Frequency Hopping with Channel Prediction
(Master thesis, 2006)The number of radio systems operating in the 2.4 GHz band is rising as a result of increased usage of wireless technologies. Since such devices interfere with one another, satisfactory co-existence becomes important. Several ... -
An Optimized Cross-Layer Protocol For Patient Confined Wireless Network
(Master thesis, 2007)Mobility and freedom are two driving forces for research in wireless sensor networks. Recent advances in hardware development, offering low-cost, low-power sensor devices open up for an exciting research field where only ... -
