A criterion for the equivalence of formal singularities

American Journal of Mathematics, 2002
We prove a generalization of the finite determinacy theorem for isolated singularities. The maximal ideal occuring in the finite determinacy theorem is replaced by any ideal annihilating the first cotangent cohomology of a formal singularity over a Noetherian ring. An analogous result holds for finitely generated modules.

On the establishment of equivalence acceptance criterion in analytical similarity assessment

Journal of Biopharmaceutical Statistics, 2017
For the assessment of biosimilarity of biosimilar products, the United States (US) Food and Drug Administration (FDA) proposed a stepwise approach for providing the totality-of-the-evidence of similarity between a proposed biosimilar product and a US-licensed (reference) product.

Effects of mastery criterion on the emergence of derived equivalence relations

Journal of Applied Behavior Analysis, 2017
In this study, we manipulated mastery criterion form (rolling or block) and stringency (across 6 or 12 trials) and measured the emergence of derived relations. College students learned neuroanatomy equivalence classes and experienced one of two rolling mastery criteria (6 or 12 consecutive correct responses) or a block mastery criterion (12 trials in a

Establishment of an Equivalence Acceptance Criterion for Accelerated Stability Studies

Journal of Biopharmaceutical Statistics, 2013
In this article, the use of statistical equivalence testing for providing evidence of process comparability in an accelerated stability study is advocated over the use of a test of differences. The objective of such a study is to demonstrate comparability by showing that the stability profiles under nonrecommended storage conditions of two processes ...

A Criterion for the Equivalence of Exponent Matrices

Mathematical and computer modelling. Series: Physical and mathematical sciences
The paper establishes a criterion for the equivalence of reduced exponent matrices in terms of weighted admissible quivers. Exponent matrices arise naturally in the theory of tiled orders over discrete valuation rings and determine a number of structural properties of such orders, including their quivers.

Integrability Criterion of Geodesical Equivalence. Hierarchies

Acta Applicandae Mathematica, 1999
The subject of geodesically equivalent Riemannian metrics, i.e., metrics with the same geodesic lines, has a long history, beginning with \textit{U. Dini} [Brioschi Ann. (2) III, 269-294 (1870; JFM 02.0622.02)]. Because Riemannian metrics are produced by Hamiltonians in a straightforward manner, it results that the implications of geometry of such ...

On equivalence between stress criterion and stiffness criterion in evolutionary structural optimization

Structural Optimization, 1999
In a finite element analysis (FEA), the contours of element von Mises stress and stiffness sensitivity number are found to be very similar. This paper shows there to be an equivalence between the von Mises stress criterion and the stiffness criterion for element elimination or addition in evolutionary structural optimization.

Criterion based equivalence for equation error models

IEEE Transactions on Automatic Control, 1989
An equivalence relation is investigated that is used when parametrizing a set of linear time-invariant models for applying equation error system identification methods. In order to obtain identified models that are not dependent on the specific parametrization of the model set, a notion of model equivalence is introduced that is related to the ...

A Weighted Dual Criterion for the Problem of Equivalent Replacement

Vulnerability, Uncertainty, and Risk, 2014
The problem of equivalent replacement plays a basic role in many fields of science and technology. In the classical approach the original object A is to be replaced by an equivalent object kB by using the mean square minimum criterion. When the difference between A and B is significant the replacement leads to unaccepted errors.

Criterion for propagation of magnetohydrodynamic waves: An equivalence

Astrophysics and Space Science, 1975
It is shown that the requirement that a magnetohydrodynamic wave propagate over a distance equal to a large number of wavelengths without substantial attenuation is equivalent to the requirement that the lateral velocity of displacement of the field lines far exceed a characteristic velocity.
