Sport Medicine

The analysis of multivariate time series about limp angles and muscle activity during Inline Speed-Skating was done using the with the Time Series Knowledge Mining. The resulting temporal patterns describe typical coordination patterns of muscles during repetitive movements. The pattern descriptions can be used for rehabilitation therapy and training optimization.

DNA Microarrays

In an analysis of DNA microarray we were able to extract the most relevant attributes from a set of 4000 genes. The reduction led to 19 genes particulariy well suited for prediction of an illness. This large decrease in complexity made it possible to perform a more detailed analysis of the function for those genes. First results indicate new insights into the growth of cancer for small kids.
