The abnormal eye movements are distinctive, being multidirectional and of high amplitude. Its recognition helps in the diagnosis of this clinical syndrome, the correct identification of which leads to the ...

We introduce revlex-initial 0/1-polytopes as the convex hulls of reverse-lexicographically initial subsets of 0/1-vectors. These polytopes are special knapsack-polytopes. It turns out that they have remarkable extremal properties. In particular, we use these polytopes in order to prove that the minimum numbers gnfac(d, n) of facets and the minimum average degree gavdeg(d, n) of the graph of a d...

Erratic Dancing

The problem of classifying dance songs according to rhythms has recently been introduced in [4] and [3]; in this paper, we present new efficient algorithms that take into account temporal errors, which could not be handled by the algorithms presented in [4] and [3]. We analyze and compare the running times of two algorithmic variants and furthermore show examples of their implementation.
