- Non-invasive multi-frequency measurements of transcephalic impedance, both reactance and resistance, can efficiently detect cell swelling of brain tissue and can be used for early detection of threatening brain damage. We have performed experiments on piglets to monitor transcephalic impedance during hypoxia. The obtained results have confirmed the hypothesis that changes in the size of cells modify the tissue impedance. During tissue inflammation after induced hypoxia, cerebral tissue exhibits changes in both reactance and resistance. Those changes are remarkably high, up to 71% over the baseline, and easy to measure especially at certain frequencies. A better understanding of the electrical behaviour of cerebral tissue during cell swelling would lead us to develop effective non-invasive clinical tools and methods for early diagnosis of cerebral edema and brain damage prevention.

Konferensbidrag (refereegranskat)abstract
- In this vision paper I will discuss a few questions concerning the use of generative processes in composition and automatic music creation. Why do I do it, and does it really work? I discuss the problems involved, focusing on the use of interactivity, and describe the use of interactive evolution as a way of introducing interactivity in composition. The installation MutaSynth is presented as an implementation of this idea.

FSED - feature selective edge detection

Konferensbidrag (refereegranskat)abstract
- We present a method that finds edges between certain image features, e.g. gray-levels, and disregards edges between other features. The method uses a channel representation of the features and performs normalized convolution using the channel values as certainties. This means that areas with certain features can be disregarded by the edge filter. The method provides an important tool for finding tissue specific edges in medical images, as demonstrated by an MR-image example.
