A simplified viewpoint of hyperstability
IEEE Transactions on Automatic Control, 1968The 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.

Rigidity of hyperstable complexes
Archiv der Mathematik, 2008A module J over a ring \(\bigwedge\) is said to be hyperstable when \(J \cong J \oplus {\bigwedge}^{\infty}\). Over a module M for which Ext\(^{n+1}(M, \bigwedge) = 0\) we show that the projective n-stems \({\mathcal{P}}\) for which \(\pi_n({\mathcal{P}})\) is hyperstable constitute a single homotopy type.

ASYMPTOTIC HYPERSTABILITY OF A CLASS OF NEURAL NETWORKS
International Journal of Neural Systems, 1999This paper is concerned with the asymptotic hyperstability of recurrent neural networks. We derive based on the stability results necessary and sufficient conditions for the network parameters. The results we achieve are more general than those based on Lyapunov methods, since they provide milder constraints on the connection weights than the ...

Abstract Lascar rank is localized to invariant families of types, and some of its properties are proven. Furthermore, the regular type technology is extended to certain stable theories. This is applied to prove Lachlan’s conjecture for those theories, and derive further structural properties.

Hyperstable arousal regulation in multiple sclerosis
Psychoneuroendocrinology, 2019Fatigue 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 ...

Fuzzy adaptive control: a hyperstability approach
ICECS 2000. 7th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.00EX445), 2002This paper investigates a direct fuzzy adaptive control of continuous-time nonlinear systems. The proposed adaptive scheme uses a Takagi-Seguno (TS) fuzzy controller, which allows the inclusion of a priori information in terms of qualitative knowledge about the plant operating points or analytical conventional regulators (e.g., state feedback) for ...

Hyperstability and adaptive filtering
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1981Recently, 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 ...

Hyperstable polyphase adaptive IIR filters
1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999This work considers the implementation of recursive identification algorithms based on hyperstability concepts with polyphase structures. It is shown that the strictly positive real (SPR) condition required for convergence of these schemes can always be met by using a sufficiently high polyphase expansion factor M.
