Massive amount of time series data are generated daily, in areas as diverse as astronomy, industry, sciences, and aerospace, to name just a few. One obvious problem of handling time series databases concerns with its typically massive size—gigabytes or even terabytes are common, with more and more databases reaching the petabyte scale. Most classic data mining algorithms do not perform or scale...

A new method for temporal pattern matching of a time series is developed using pattern wavelets and genetic algorithms. The pattern wavelet is applied to the matching of an embedded time series. A problem-specific fitness factor is introduced in the new algorithm, which is useful to construct a fitness function of the feature space. A two-step process discovers the pattern wavelet that yields h...

Many crimes can happen every day in a major city, and figuring out which ones are committed by the same individual or group is an important and difficult data mining challenge. To do this, we propose a pattern detection algorithm called Series Finder, that grows a pattern of discovered crimes from within a database, starting from a “seed” of a few crimes. Series Finder incorporates both the com...

Remarkable differences in the shape of the nematic–smectic-B interface in a quasi-two-dimensional geometry have been experimentally observed in three liquid crystals of very similar molecular structure, i.e., neighboring members of a homologous series. In the thermal equilibrium of the two mesophases a faceted rectanglelike shape was observed with considerably different shape anisotropies for t...

Distributed Aircraft maintenance Environment (DAME) is a major UK eScience Grid project aiming to build a Grid test-bed for Distributed Diagnostics. The main challenge of the DAME project is the design and implementation of a fault diagnosis and prognosis system over the Grid computing infrastructure. This paper examines how the Grid may effect the implementation of search engines by focusing o...

The distribution of ordinal patterns in time series has been found to reflect important qualitative features of the underlying system dynamics. Abrupt changes in the dynamics typically result in clearly visible differences between the distributions before and after the break. Recurring dynamical regimes can be discovered by classifying the distributions in different parts of the time series. Th...

Abstract. In combinatorics on words, a word w over an alphabet Σ is said to avoid a pattern p over an alphabet ∆ if there is no factor x of w and no non-erasing morphism h from ∆∗ to Σ∗ such that h(p) = x. Bell and Goh have recently applied an algebraic technique due to Golod to show that for a certain wide class of patterns p there are exponentially many words of length n over a 4-letter alpha...
