While it is tempting in experimental practice to seek as high a data rate possible, oversampling can become an issue if one takes measurements too densely. These effects take many forms, some of which are easy detect: e.g., when the sequence contains multiple copies same measured value. In other situations, there mixing$-$in measurement apparatus and/or system itself$-$oversampling be harder de...

This paper deals with the development of two symmetric encryption algorithms on basis cellular automata: a block cipher, that is based AES and uses three-dimensional automata; stream exploits hardware-software entropy generation (tracking keystrokes mouse pointer movement), as well developed hash function, “cryptographic sponge” architecture SHA-3, modified by automata transformations. The ciph...

Permutation distribution clustering is a complexity-based approach to clustering time series. The dissimilarity of time series is formalized as the squared Hellinger distance between the permutation distribution of embedded time series. The resulting distance measure has linear time complexity, is invariant to phase and monotonic transformations, and robust to outliers. A probabilistic interpre...
