Advanced Engineering Materials, EarlyView.In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

The condition for dynamic stability
Journal of Biomechanics, 2005The well-known condition for standing stability in static situations is that the vertical projection of the centre of mass (CoM) should be within the base of support (BoS). On the basis of a simple inverted pendulum model, an extension of this rule is proposed for dynamical situations: the position of (the vertical projection of) the CoM plus its ...

Stability of dynamical systems [PDF]
Nonlinearity, 1988 The author gives the following new definitions of the stability of ordinary differential equations. Given a vector field v on an oriented manifold X and given \(\epsilon >0\), let u be the steady state of the Fokker-Planck equation for v with \(\epsilon\)-diffusion. Existence, uniqueness and global attraction of u is proved when X is compact.

This article aims to show the mathematical contexts out of which emerged Solow's 1957 article “Technical Change and the Aggregate Production Function.” In particular, it seeks to provide some understanding of its most striking feature, namely, the highly aggregate level on which technical change is discussed and the simple way in which it is ...

Abstract We accord with Mike Long’s rejection of fossilization as a concept able to describe or explain second language acquisition. And we share his bewilderment (Long, 2003, p. 512f.) that since most studies of fossilization make reference to explanatory factors external to language and cognition, “[s]urprisingly, no one seems to have considered the ...

On Stability of a Dynamical System
SIAM Journal on Mathematical Analysis, 1995This paper solves an open problem raised by \textit{E. C. Zeeman} [Nonlinearity 1, 115-155 (1988; Zbl 0643.58005)]. It extends his results about the stability of a dynamical system from \(C^ \infty\)-vector fields to \(C^ m\)-vector fields \((1 \leq m \leq \infty)\).
