Dynamical Sampling: A Survey
Akram Aldroubi, Carlos Cabrelli, Ilya Krishtal +1
Dynamical sampling refers to a class of problems in which space-time samples are taken from a signal evolving under an underlying dynamical system. The goal is to use these samples…
Reconstructing Graph Signals from Noisy Dynamical Samples
Akram Aldroubi, Victor Bailey, Ilya Krishtal +2
We investigate the dynamical sampling space-time trade-off problem within a graph setting. Specifically, we derive necessary and sufficient conditions for space-time sampling that…
Periodic Source Detection in Discrete Dynamical Systems via space-time sampling
Akram Aldroubi, Carlos Cabrelli, Ursula Molter
In this paper, we examine a discrete dynamical system defined by x(n+1) = Ax(n)+ w(n), where x takes values in a Hilbert space H and w is a periodic source with values in a fixed c…
Reconstruction algorithms for source term recovery from dynamical samples in catalyst models
Akram Aldroubi, Le Gong, Ilya Krishtal +2
This paper investigates the problem of recovering source terms in abstract initial value problems (IVP) commonly used to model various scientific phenomena in physics, chemistry, e…
Characterization of frames for source recovery from dynamical samples
Akram Aldroubi, Rocio Diaz Martin, Le Gong +2
In this paper, we address the problem of recovering constant source terms in a discrete dynamical system represented by , where is the -th state in a H…
Dynamical Sampling for the Recovery of Spatially Constant Source Terms in Dynamical Systems
Akram Aldroubi, Rocio Diaz Martin, Ivan Medri
In this paper, we investigate the problem of source recovery in a dynamical system utilizing space-time samples. This is a specific issue within the broader field of dynamical samp…
