Reservoir Sampling over Memory-Limited Stream Joins
In stream join processing with limited memory, uniform random sampling is useful for approximate query evaluation. In this paper, we address the problem of reservoir sampling over...

The Korteweg-de Vries-Kawahara equation in a bounded domain and some numerical results
We are concerned with the initial-boundary problem associated to the Korteweg–de Vries–Kawahara perturbed by a dispersive term which appears in several fluids dynamics proble...

Indexing high-dimensional data in dual distance spaces: a symmetrical encoding approach
Due to the well-known dimensionality curse problem, search in a high-dimensional space is considered as a "hard" problem. In this paper, a novel symmetrical encoding-bas...
