Feedback for neuronal system identification
… that the data be generated by a process with a fading memory. Non-equilibrium systems such as neuronal and chaotic models lack a fading memory. Their identification is challenging, in particular in the presence of input noise. In this thesis, we propose a methodology based on the …

On the Theory of Diffusion in Linear Viscoelastic Media
… considered. The concepts of chemical potential, fading memory, and a correspondence principle are discussed. The general development is concluded with an illustrative example.

Limite de Stokes: uma aproximação estável para escoamentos lentos de fluidos não Newtonianos
… procedure for slow flows of simple fluids with fading memory is studied. Grounded on Coleman & Noll's aproximation theorem, the procedure aims to avoid the cases of instability that may occur when the fluids of Rivlin-Ericksen are applied. We investigate the conjecture that the instability is …

Disordered Optics for Multidimensional Information Processing
… We identify the trade-off between the fading memory and non-normality of scattering RC, which determines their memory capacity and resistance to noise. Further, we proposed a transient amplification method to fully harness the high noise resistance and high dimensionality of non-normal …

Adaptive finite elements for viscoelastic deformation problems
… solutions to problems involving materials with fading memory, known as viscoelastic materials. Viscoelastic materials can be loosely described as those whose current stress configuration depends on their recent past. Viscoelastic constitutive laws for stress typically take the form of a sum of …

The investigation and design of a machine vision system for the detection and control of the separation in a spinal ore concentrator
… incorporates a median filter, followed by a fading-memory polynomial filter. These filters gave sufficient smoothing with little lag to step changes in ore concentration. The efficiency of the ore separation was monitored by the determination of losses. These losses consist of, the percentage …

Universal approximation of input-output maps and dynamical systems by neural network architectures
… input-output maps having limited long-term memory, we prove universal approximation guarantees for temporal convolutional nets constructed using only a finite number of computation units which hold on an infinite-time horizon. We also provide quantitative estimates for the width and depth of …

ΑΣΥΠΤΩΤΙΚΗ ΣΥΜΠΕΡΙΦΟΡΑ ΤΗΣ ΕΝΕΡΓΕΙΑΣ ΒΙΣΚΟΕΛΑΣΤΙΚΩΝ ΚΥΜΑΤΩΝ
THIS THESIS REFERS TO THE ENERGY BEHAVIOUR OF A LINEARIZED VISCOELASTIC MODEL, IN AN ISOTROPIC AND HOMOGENEOUS MEDIUM WITH QUIET PAST, WHOSE VISCOELASTIC BEHAVIOUR IS EXPRESSED BY MEANS OF RELAXATION FUNCTION WHICH DECAY EXPONENTIALLY INTIME. A REGULAR DISTURBANCE WITH COMPACT SUPPORT IS …
