This paper discusses an effective processing of similarity search that supports time warping in large sequence databases. Time warping enables finding sequences with similar patterns even when they are of different lengths. Previous methods for processing similarity search that supports time warping fail to employ multi-dimensional indexes without false dismissal since the time warping distance...

a unified approach to zero crossings and nonuniform sampling of single and multidimensional signals and systems. Book lovers, when you need a new book to read, find the book here. Never worry not to find what you need. Is the a unified approach to zero crossings and nonuniform sampling of single and multidimensional signals and systems your needed book now? That's true; you are really a good re...

SUMMARY Time-warping is a signal processing technique that, when applied to an isolated measurement of transient that propagates in waveguide, allows contributions from individual mode numbers be and extracted. Dispersion curves for can, turn, recovered. Isolation associated with possible because after time-warping—a special environmentally dependent non-uniform sampling—is applied, the energy ...

We analyze the electronic structure of topological surface states in family magnetic insulators MnBi$_{2n}$Te$_{3n+1}$. show that, at natural-cleavage surfaces, Dirac cone warping changes its symmetry from hexagonal to trigonal ordering temperature. In particular, an energy splitting develops between same band index but opposite momenta upon formation long-range order. As a consequence, measure...

In this paper, a novel pitch mean based frequency warping (PMFW) method is proposed to reduce the pitch variability in speech signals at the frontend of speech recognition. The warp factors used in this process are calculated based on the average pitch of a speech segment. Two functions to describe the relations between the frequency warping factor and the pitch mean are defined and compared. W...

This paper examines techniques for normalization of unseen speakers in recognition. Two implementations of linear spectrum warping were examined: time domain resampling and filter bank scaling. It is shown that for seen speakers, the models trained by unwarped utterances are less sensitive to spectrum warping by filter bank scaling than by resampling. A pitch-based scheme for warping factor est...

Atherosclerotic plaque rupture is responsible for the majority of myocardial infarctions and acute coronary syndromes. Rupture is initiated by mechanical failure of the plaque cap, and thus study of the deformation of the plaque in the artery can elucidate the events that lead to myocardial infarction. Intravascular ultrasound (IVUS) provides high resolution in vitro and in vivo cross-sectional...
