Speech field is affected by accidental structures such as spurious events and artifacts (breath mouth, lip clicks etc). Because the whole utterance is used during training and the identification process, these factors may represent confusable acoustic classes which do not contribute to the performance of the speaker recognition system. In this paper we propose a new approach for extracting as m...

We prove a pointwise version of the multi-dimensional central limit theorem for convex bodies. Namely, let μ be an isotropic, log-concave probability measure on Rn. For a typical subspace E ⊂ Rn of dimension nc, consider the probability density of the projection of μ onto E. We show that the ratio between this probability density and the standard gaussian density in E is very close to 1 in larg...

I discuss heavy quarkonium radiative transitions and the related issue of the quarkonium magnetic moment inside effective field theories. Differences in set up and conclusions with respect to typical phenomenological approaches are outlined. Heavy quarkonium radiative transitions have been studied for long time in the framework of phenomenological models 1–14 (for a recent review see 15). In a ...

Hugh Everett III presented pure wave mechanics, sometimes referred to as the many-worlds interpretation, as a solution to the quantum measurement problem. While pure wave mechanics is a deterministic physical theory with no probabilities, Everett sought to show how the theory might be understood as making the standard quantum statistical predictions as appearances to observers who were themselv...

This expository paper advocates an approach to physics in which “typicality” is identified with a suitable form of algorithmic randomness. To this end various theorems from mathematics and are reviewed. Their original versions state that some property Φ(x) holds for P-almost all x∈X, where P probability measure on space X. more refined (and typically recent) formulations show P-random x∈X. The ...

Dynamic characteristics of a typical multistory building in Iran have been studied in two different stages of building construction, using ambient vibration tests. Finite element models have also been used to determine these characteristics and to verify test results. The results indicated the agreements and also differences between conventional theoretical models and the behaviour of real stru...
