Hyperstability and average hyperstability conditions for a broad class of gaussian stochastic systems

Information Sciences, 1979
Abstract The author investigates the hyperstability problem for a broad class of single-control stochastic systems which may be considered as disturbed models of given deterministic systems. The stochasticity comes from the control, which is disturbed by an additive Gaussian noise with its own gain.

Hyperstability and identification

1970 IEEE Symposium on Adaptive Processes (9th) Decision and Control, 1970
This paper considers the process identification by means an adjustable model. An approach to the synthesis of this type of on-line identification system via the hyperstability theory is proposed. Two typical situations for identification are considered (the "ideal case" and the "real case").

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 GENERALISED LINEAR FUNCTIONAL EQUATIONS IN SEVERAL VARIABLES

Bulletin of the Australian Mathematical Society, 2020
Zhang [‘On hyperstability of generalised linear functional equations in several variables’, Bull. Aust. Math. Soc.92 (2015), 259–267] proved a hyperstability result for generalised linear functional equations in several variables by using Brzdęk’s fixed ...

Parameter optimized hyperstable controllers

[1991] Proceedings of the 30th IEEE Conference on Decision and Control, 2002
A parameterization of hyperstable linear time-invariant controllers is proposed, where the free parameters are to be determined by parameter optimization in order to meet various design requirements of the closed-loop system. The class of hyperstable controllers is of special importance since a control loop with hyperstable controller is guaranteed to ...

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 ...

Aza-Glycine Induces Collagen Hyperstability

Journal of the American Chemical Society, 2015
Hydrogen bonding is fundamental to life on our planet, and nature utilizes H-bonding in nearly all biomolecular interactions. Often, H-bonding is already maximized in natural biopolymer systems such as nucleic acids, where Watson-Crick H-bonds are fully paired in double-helical structures.

Hyperstable arousal regulation in multiple sclerosis

Psychoneuroendocrinology, 2019
Fatigue is common in multiple sclerosis (MS) patients. Exhaustion of physiological reserves and mental stress are postulated causes, the latter supported by more pronounced hypothalamic-pituitary-adrenal (HPA) axis activation in fatigued patients. Divergent dysregulation of arousal appears to play important roles in depression- (hyperstable arousal ...

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.

Hyperstability and adaptive filtering

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1981
Recently, results from the area of system identification concerning the concept of system hyperstability have been applied to the analysis of adaptive filtering configurations. In particular, this analysis tool has allowed the development of a family of convergent adaptive recursive digital filtering algorithms, where the use of conventional gradient ...
