The Markov Expert for Finding Episodes in Time Series
We describe a domain-independent, unsupervised algorithm for refined segmentation of time series data into meaningful episodes, focusing on the problem of text segmentation. The V...

Efficient String Matching Algorithms for Combinatorial Universal Denoising
Inspired by the combinatorial denoising method DUDE [13], we present efficient algorithms for implementing this idea for arbitrary contexts or for using it within subsequences. We...

Error Concealment for Dual Frame Video Coding with Uneven Quality
When losses occur in a transmission of compressed video, the decoder can attempt to conceal the loss by using spatial or temporal methods to estimate the missing macroblocks. We c...

TetStreamer: Compressed Back-to-Front Transmission of Delaunay Tetrahedra Meshes
We use the abbreviations tet and tri for tetrahedron and triangle. TetStreamer encodes a Delaunay tet mesh in a back-to-front visibility order and streams it from a server to a cl...

On the Existence of Large Sets of t-designs of Prime Sizes
In this paper, we employ the known recursive construction methods to obtain some new existence results for large sets of t-designs of prime sizes. We also present a new recursive ...
