The fractal dimension of pullback attractors for the 2D Navier–Stokes equations with delay

Mathematical methods in the applied sciences, 2020
This paper is concerned with the bounded fractal and Hausdorff dimension of the pullback attractors for 2D nonautonomous incompressible Navier‐Stokes equations with constant delay terms.

PULLBACK ATTRACTORS AND INVARIANT MEASURES FOR THE DISCRETE ZAKHAROV EQUATIONS

The Journal of Applied Analysis and Computation, 2019
This article studies the probability distributions of solutions in the phase space for the discrete Zakharov equations. The authors first prove that the generated process of the solutions operators possesses a pullback-D attractor, and then they ...

Learning Pullback HMM Distances

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014
Recent work in action recognition has exposed the limitations of methods which directly classify local features extracted from spatio-temporal video volumes. In opposition, encoding the actions' dynamics via generative dynamical models has a number of attractive features: however, using all-purpose distances for their classification does not ...

Near Real-Time HDD Pullback Force Prediction Model Based on Improved Radial Basis Function Neural Networks

, 2020
Pipeline pullback is a crucial part of horizontal directional drilling (HDD) construction. Accurate pullback force prediction is the prerequisite for ensuring construction safety.

Tail convergences of pullback attractors for asymptotically converging multi-valued dynamical systems

Asymptotic Analysis, 2019
In this paper we study pullback attractors of multi-valued dynamical systems that are asymptotically convergent. It is shown that, under certain conditions, the components of the pullback attractor of a dynamical system can converge in time to those of ...

The pullback attractor

2012
The global attractor, whose well established definition we recall below, is an object that captures the asymptotic behaviour of autonomous systems. The aim of this chapter is to introduce the ‘pullback attractor’, which seems to be the correct generalisation of this concept for use with non-autonomous processes.
