Elliptical ultrasonic vibration-assisted milling (EUVAM) adds high-frequency vibration to conventional (CM) realize intermittent milling. It has broad application prospects in the processing of difficult-to-cut materials such as titanium alloys, superalloys, and hard brittle materials. To reveal mechanism highly cutting nature EUVAM, according motion relationship between edge workpiece Z-map re...

because of the complex and variable environment of media organization, its need a road map to help them to manage this environment and respond effectively to sudden changes in front of that. policy making in media organization can play an important role in this regard. in this study has been studied the policy-making process in the islamic republic of iran broadcasting (irib) and damages of thi...

Introduction: The central mechanism related to the cardiovascular response to lipopolysaccharide (LPS)-induced hypotension is not entirely known, but it is suggested that numerous brain areas such as dorsal periaqueductal gray (dPAG) are involved in this process. In the current work, the cardiovascular effect of the dPAG during LPS-induced hypotension is investigated. Methods: The study animal...

The standard combinatorial approximation C(R n, X) to Qn~nx is a filtered space with easily understood filtration quotients Di Rn, X). Stably, C( Rn, X) splits as the wedge of the Di Rn, X). We here analyze the multiplicative properties of the James maps which give rise to the splitting and of various related combinatorially derived maps between iterated loop spaces. The target of the total Jam...

This note is devoted to the differentiability properties of H-Lipschitz maps defined on abstract Wiener spaces and with values in metric spaces, so we start by recalling some basic definitions related to the Wiener space structure. Let (E, ‖ · ‖) be a separable Banach space endowed with a Gaussian measure γ. Recall that a Gaussian measure γ on E equipped with its Borel σ−algebra B is a probabil...

Let Ω ⊂ R be a bounded Lipschitz domain, F : Rn×n → R a suitably quasiconvex integrand and consider the energy functional

We provide a mild mixing condition that carries the C.L.T. for normalized empirical means of centered stationary sequence of bounded random variables to the whole range of moderate deviations. It is also key for the exponential convergence of the laws of empirical means. The motivating example for this work are iterates of expanding maps, equipped with their unique invariant measure.
