Stability of walking frames.
Biomechanical tools were used to assess stability for 11 patients who, following the surgical amputation of one lower limb, required the assistance of a walking frame to ambulate. The Walker Tipping Index (WTI), as derived from the forces applied to the walking frame, was developed specifically for this study to examine the relationship between stability and walking frame height during ambulati...
متن کاملStability of G-frames
G-frames are natural generalizations of frames which cover many other recent generalizations of frames, e.g., bounded quasi-projectors, frames of subspaces, outer frames, oblique frames, pseudo-frames and a class of timefrequency localization operators. Moreover, it was shown that g-frames are equivalent to stable space splittings. In this paper, we study the stability of g-frames. We first pre...
متن کاملAsking Queries about Frames
Frame-based knowledge representation and reasoning systems typically provide procedural interfaces for asking about properties of individuals and concepts. We propose an alternative declarative approach that extends standard interface functionality by supporting selective viewing of components of complex objects. Instead of just returning sets of individuals, our queries match concepts and lter...
متن کاملSome Results About Frames
In this paper we discuss some topics related to the general theory of frames. In particular we focus our attention to the existence of different ’reconstruction formulas’ for a given vector of a certain Hilbert space and to some refinement of the perturbative approach for the computation of the dual frame.
متن کاملStability Analysis for Pitched Portal Frames of Fibre Reinforced Polymer
In this paper the analysis method from Majid (1963) for steel pitched portal frames is progressed so that we can study the influence of shearing action on the overall elastic critical buckling load when members are of Fibre Reinforced Polymer (FRP) material. For solid members of FRP the ratio of the longitudinal Young’s modulus to the shear modulus of elasticity can be significantly higher than...
