Balance perturbations

2018
Impairments of balance and gait leading to loss of mobility, falls, and disability are common occurrences in many neurologic conditions and with older age. Much of our current understanding about posture and balance control and its impairments has come from investigations of how healthy individuals and those with neurologic disorders respond to ...

Fuzzy perturbation analysis, part I: Directional perturbation

Fuzzy Sets and Systems, 1985
A new idea, fuzzy perturbation, is advanced. The stability of the solutions of a fuzzy relation equation and the generalized solution of the unsolvable equation are defined by means of this idea. Thereupon, a part of the theory of fuzzy perturbation analysis, fuzzy directional perturbation, is formed.

Perturbation Theory: Relatively Bounded Perturbations

1996
We have so far discussed two aspects of perturbation theory: perturbations of self-adjoint operators which preserve self-adjointness, and perturbations of self-adjoint operators which preserve the essential spectrum. This latter subject is part of what we call spectral stability.

Perturbation theory for odd perturbations

Journal of Physics A: General Physics, 1972
The eigenvalues of perturbed Schrodinger equation with an odd perturbation are even functions of the perturbation parameter lambda . It is shown how to transform the perturbed equation so that the new perturbation is also explicitly an even function of lambda .

Geometric space-time perturbation. I. Multiparameter perturbations

Journal of Mathematical Physics, 1987
The standard definition of space-time perturbation is reexamined. It is seen that the noninvariance of the metric under identification gauge transformations is a consequence of the adopted zero signature in the fifth dimension of the space of space-times.

Quasilinear singularly perturbed problem with boundary perturbation

Journal of Zhejiang University-SCIENCE A, 2004
A class of quasilinear singularly perturbed problems with boundary perturbation is considered. Under suitable conditions, using theory of differential inequalities we studied the asymptotic behavior of the solution for the boundary value problem.

"Perturbations"

2023
Ce texte est structuré en trois parties dans lesquelles nous faisons des allers-retours permanents entre notre expérience de création, notre réflexion sur la statut critique et récalcitrant de l'artiste dans la société, sur le besoin vital de donner un sens à chacune de nos performances artistiques, politiques, éthiques, pédagogiques.En cette période ...
