Abstract We consider a class of functional differential equations with variable impulses and we establish new stability results. We discuss the variational stability and variational asymptotic stability of the zero solution of a class of generalized ordinary differential equations where our impulsive functional differential equations can be embedded ...

A Novel Family of Adaptive Filtering Algorithms Based on The Logarithmic Cost [PDF]
We introduce a novel family of adaptive filtering algorithms based on a relative logarithmic cost. The new family intrinsically combines the higher and lower order measures of the error into a single continuous update based on the error amount.

Impulsive perturbations to differential equations: stable/unstable pseudo-manifolds, heteroclinic connections, and flux [PDF]
State-dependent time-impulsive perturbations to a two-dimensional autonomous flow with stable and unstable manifolds are analysed by posing in terms of an integral equation which is valid in both forwards- and backwards-time.

In the present work, we study discontinuous impulsive systems of the type of Cohen-Grossberg Neural Networks (CGNNs) with time-varying delays. The impulsive perturbations are realized not at fixed moments of time, and can be considered as control inputs. The hybrid concept of practical exponential stability with respect to specific manifolds defined by

Experiments on the Richtmyer–Meshkov instability: single-scale perturbations on a continuous interface [PDF]
We report on experiments to measure the shock-induced growth of sinusoidal perturbations on thick interfaces separating two gases of different densities. The results show that the growth rates are reduced as the interface thickness is increased.

A Unified Theory for the Effects of Stellar Perturbations and Galactic Tides on Oort Cloud Comets [PDF]
We examine the effects of passing field stars on the angular momentum of a nearly radial orbit of an Oort cloud comet bound to the Sun. We derive the probability density function (PDF) of the change in angular momentum from one stellar encounter ...

Impulsive Delayed Lasota–Wazewska Fractional Models: Global Stability of Integral Manifolds
In this paper we deal with the problems of existence, boundedness and global stability of integral manifolds for impulsive Lasota−Wazewska equations of fractional order with time-varying delays and variable impulsive perturbations. The main results
