In this article we mainly aim to know what kind of asymptotic behavior typical orbits can display. For example, show in any transitive system, the empirical measures a orbit cover all dense and intersect some physical-like measures. particular, if union set is not singleton, then will display historic simultaneously for continuous functions limit ergodic average along every function equals clos...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

Community public space is an important place for daily communication between residents. In the context of current historical change “urban double repairs”, community renewal has raised new heights, and shifted from surface physical transformation layer to protection, inheritance environmental quality community. This article summarizes concept principles micro-renewal, analyzes related influenci...

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 ...

A typical dynamometer drive shaft was damaged during its working condition. This failure was repeated in four cases. In the present article, a failure analysis of a dynamometer drive shaft has been performed. To analyze the failure, the material investigation was carried out by scanning electron microscopy (SEM) images. Additionally, the micro-structure of the failed coupling shaft was photogra...
