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 ...

A cantilever loaded at its free end is used to introduce the subject of dynamic stability, including non-conservative axial external force such as the case presented at the end of Chap. 8. The essential difference between divergence instability with zero eigenfrequency and flutter instability, i.e., vibration with increasing amplitude is discussed. The

Dynamic glenohumeral joint stability
Journal of Shoulder and Elbow Surgery, 1998Stability of the glenohumeral joint with an anterior, posterior, and inferior displacement force of 50 N was measured in a dynamic shoulder model. Controlled hydrodynamic actuator forces were applied to the deltoid muscle and to the rotator cuff in seven anatomic specimens. During elevation of the arm the position of the humerus was measured with a six-

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 ...

It is shown how stability theory of dynamic systems, emerging from various beginnings strewn over the realm of mechanics, developed into a unified, comprehensive theory for dynamic systems with a finite number of degrees of freedom. It is then demonstrated, how such theory could be adapted over the last five decades to the specific nature of stability ...

States are considered as dynamically stable if they are invariant under a time automorphism and depend smoothly on a perturbation of the dynamics. We study the consequences for finite systems and compare it with the consequences in infinite systems. With an appropriate definition of smoothness it is shown that states that are dynamically stable are ...

This work is a study of the stability of a straight dynamically propagating crack to small perturbation of its path. Obrezanova et al. in [1] investigated stability of a crack propagating through an infinite elastic medium loaded by remote body forces following the crack as it advances.
