Subband hyperstable adaptive iir filters

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2003
Two subband implementations of hyperstability based adaptive infinite-impulse response (IIR) filtering algorithms are presented. These schemes are based on the polyphase decomposition of the adaptive filter and do not require cross filters to avoid aliasing.

In Vitro Evolution of a Hyperstable Gβ1 Variant

Journal of Molecular Biology, 2006
An in-vitro selection strategy was used to obtain strongly stabilized variants of the beta1 domain of protein G (Gbeta1). In a two-step approach, first candidate positions with a high potential for stabilization were identified in Gbeta1 libraries that were created by error-prone PCR, and then, after randomization of these positions by saturation ...

Hyperstability of the Jensen functional equation

Acta Mathematica Hungarica, 2013
\textit{S.-M. Jung}, \textit{M. S. Moslehian} and \textit{P. K. Sahoo} [J. Math. Inequal. 4, No. 2, 191--206 (2010; Zbl 1219.39016)] investigated the conditional stability of the generalized Jensen functional equation \(f(ax+by)=af(x)+bf(y)\). Based on a fixed point method, the authors of the present paper consider the hyperstability problem of the ...

A simplified viewpoint of hyperstability

IEEE Transactions on Automatic Control, 1968
The definition of a hyperstable system according to Popov is given a network theoretic interpretation, and proofs are presented outlining the connection between passive and hyperstable systems.

10 MHz hyperstable quartz oscillators performances

Proceedings of the 1999 Joint Meeting of the European Frequency and Time Forum and the IEEE International Frequency Control Symposium (Cat. No.99CH36313), 2003
New hyperstable quartz oscillators are presented. Methods to overcome limitations due to various noise sources are discussed. Stabilities down to 5.10/sup -14/ are obtained together with drift down to 5.10/sup -12//day and excellent resistance to bad environmental conditions.

Hyperstability in variable structure systems

1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1980
Reaching and existence conditions for variable structure systems are considered using hyperstability theory. A new sufficient condition for linear, time invariant systems is derived, and an example is given to illustrate how the condition is more relaxed than the sufficient condition presently used for such systems.

Image filtering using hyperstable adaptive algorithms

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 1997
In view of recent interest in applications of adaptive filtering of multidimensional (m-D) signals in practical problems such as video compression and image enhancement, implementation of a class of m-D infinite impulse response, adaptive, hyperstable filters is undertaken.

A HYPERSTABILITY RESULT FOR THE CAUCHY EQUATION

Bulletin of the Australian Mathematical Society, 2013
AbstractWe prove a hyperstability result for the Cauchy functional equation$f(x+ y)= f(x)+ f(y)$, which complements some earlier stability outcomes of J. M. Rassias. As a consequence, we obtain the slightly surprising corollary that for every function$f$, mapping a normed space${E}_{1} $into a normed space${E}_{2} $, and for all real numbers$r, s$with ...

The hyperstability approach to VSCS design

1990
A systematic approach to the design of VSC systems has been given. Using the hyperstability theory, the stability of the global system has been established and the existence of the sliding modes. Simple control laws can be used and high speed of response is obtainable by forcing the system with maximum allowable signals, e.g.
