21. Signal Processing for Spectroscopic Applications
Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.

22. Non-invasive techniques for assessment of peripheral blood flow at different vascular depths
Abstract : Missing or reduced blood flow can lead to pressure ulcers. Monitoring blood flow in areas prone to pressure ulcer development would be a valuable tool for prevention of pressure ulcers. PPG and LDF are both established non invasive optical techniques that can be used to estimate the changes in blood flow in different tissue volumes. READ MORE

23. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function
Abstract : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. READ MORE

24. Microvascular effects of insulin in the skin
Abstract : The microcirculation in the skin is essential for skin homeostasis. In instances of altered microvascular function, that may be the result of insulin resistance, tissue morbidity may ensue. The underlying mechanisms are however complex and not fully understood. READ MORE

25. The Hand in Manual Work - Physiological and Psychophysical studies
Abstract : This thesis focuses on the hand in manual work. In particular, we have studied what happens to skin and muscles when gripping a hand tool. Different aspects of gripping that will be discussed are: pressure on the hand, effects on the skin blood flow, muscle activity and the use of wrist orthoses. READ MORE
