Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System
Advanced Engineering Materials, EarlyView.Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Dynamic Output Feedback Stabilization of Non-Uniformly Observable Dissipative Systems
IFAC-PapersOnLine, 2020 Output feedback stabilization of control systems is a crucial issue in engineering. Most of these systems are not uniformly observable, which proves to be a difficulty to move from state feedback stabilization to dynamic output feedback stabilization. In

On the Dynamic Stability of Grasping
The International Journal of Robotics Research, 1999Stability is one of the important properties that a robot hand grasp must possess to be able to perform tasks similar to those performed by human hands. This paper discusses the dynamic stability of a grasped object. To analyze the stability of grasps, we build the model of the dynamics of the grasped object in response to the small perturbances ...

A Novel Technique, Dynamic Intraligamentary Stabilization Creates Optimal Conditions for Primary ACL Healing: A Preliminary Biomechanical Study [PDF]
Knee, 2014 BACKGROUND Anterior cruciate ligament (ACL) rupture is a common lesion. Current treatment emphasizes arthroscopic ACL reconstruction via a graft, although this approach is associated with potential drawbacks.

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 ...

On Stability of a Dynamical System
SIAM Journal on Mathematical Analysis, 1995This note solves an open problem raised by Zeeman in [Nonlinearity, 1 (1988), pp. 115–155]. It extends his results about the stability of a dynamical system from $C^\infty $-vector fields to $C^m $-vector fields, where $1 \leq m \leq \infty $. For any $C^m $-vector field v, the existence, uniqueness, and global attraction of the steady state of the ...

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

History of Political Economy, 2009
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 ...

Dynamic stability of the scapula
Manual Therapy, 1997SUMMARY. The ability to position and control movements of the scapula is essential for optimal upper limb function. The inability to achieve this stable base frequently accompanies the development of shoulder and upper limb pain and pathology. Unlike other joints the bony, capsular and ligamentous constraints are minimal at the scapulothoracic 'joint ...
