Controllability of networks: influence of structure and memory [PDF]

open access: yes, 2023
openIn this work we borrow some ideas from the the theory of lifted Markov chains, which can accelerate convergence of random walks algorithms thanks to the introduced memory effects, and apply them to the control of networks of dynamical systems ...

Linked patterns of symptoms and cognition with brain controllability in major depressive disorder

open access: yesEuropean Psychiatry, 2023
Introduction Major depressive disorder (MDD) is characterized by both clinical symptoms and cognitive deficits. Prior studies have typically examined either symptoms or cognition correlated with brain measures, thus causing a notable paucity of stable ...

Lack of controllability of the heat equation with memory [PDF]

open access: yes, 2012
We consider a model for the heat equation with memory, which has infinite propagation speed, like the standard heat equation. We prove that, in spite of this, for every T > 0 there exist square integrable initial data which cannot be steered to hit zero ...

Controllability of linear impulsive systems – an eigenvalue approach [PDF]

open access: yes, 2020
summary:This article considers a class of finite-dimensional linear impulsive time-varying systems for which various sufficient and necessary algebraic criteria for complete controllability, including matrix rank conditions are established.

Controllability of semilinear stochastic integrodifferential systems [PDF]

open access: yes, 2007
summary:In this paper we study the approximate and complete controllability of stochastic integrodifferential system in finite dimensional spaces. Sufficient conditions are established for each of these types of controllability.

Nonequivalence of Controllability Properties for Piecewise Linear Markov Switch Processes *

open access: yesESAIM: Proceedings and Surveys, 2017
In this paper we study the exact null-controllability property for a class of controlled PDMP of switch type with switch-dependent, piecewise linear dynamics and multiplicative jumps.

Analysis of the Effect of Degree Correlation on the Size of Minimum Dominating Sets in Complex Networks. [PDF]

open access: yesPLoS ONE, 2016
Network controllability is an important topic in wide-ranging research fields. However, the relationship between controllability and network structure is poorly understood, although degree heterogeneity is known to determine the controllability. We focus

Linear Operator Inequality and Null Controllability with Vanishing Energy for Unbounded Control Systems [PDF]

open access: yes, 2013
We consider a linear boundary or point control system on a Hilbert space $H$ which is null controllable at some time $T_0 >0$. To every initial state $ y_0 \in H$ we associate the minimal ``energy'' needed to transfer $ y_0 $ to $ 0 $ in a time $ T \ge ...

Linear conformable differential system and its controllability

open access: yesAdvances in Difference Equations, 2020
This article deals with the sequential conformable linear equations. We have focused on the solution techniques of these equations and particularly on the controllability conditions of the time-invariant system.

Boundary controllability and source reconstruction in a viscoelastic string under external traction [PDF]

open access: yes, 2013
Treatises on vibrations devote large space to study the dynamical behavior of an elastic system subject to known external tractions since usually a ``system'' is part of a chain of mechanisms which disturb the ``system'' for example due to the periodic ...
