Balanced Truncation for Model Order Reduction of Linear Dynamical Systems with Quadratic Outputs [PDF]

open access: yesSIAM Journal on Scientific Computing, 2017
We investigate model order reduction (MOR) for linear dynamical systems, where a quadratic output is defined as a quantity of interest. The system can be transformed into a linear dynamical system with many linear outputs.

Linear predictors for nonlinear dynamical systems: Koopman operator meets model predictive control [PDF]

open access: yesat - Automatisierungstechnik, 2016
This paper presents a class of linear predictors for nonlinear controlled dynamical systems. The basic idea is to lift (or embed) the nonlinear dynamics into a higher dimensional space where its evolution is approximately linear.

Communicating vessels: a non-linear dynamical system

open access: yesRevista Brasileira de Ensino de Física
The dynamics of an ideal fluid contained in two communicating vessels is studied. Despite the fact that the static properties of this system have been known since antiquity, the knowledge of the dynamical properties of an ideal fluid flowing in two ...

Koopman Invariant Subspaces and Finite Linear Representations of Nonlinear Dynamical Systems for Control. [PDF]

open access: yesPLoS ONE, 2016
In this wIn this work, we explore finite-dimensional linear representations of nonlinear dynamical systems by restricting the Koopman operator to an invariant subspace spanned by specially chosen observable functions.

Some conditions of regularity of linear extensions of dynamical systems with respect to selected variables

open access: yesNonlinear Analysis, 2014
In this paper, we dealt with the issue of the regularity of the linear extension of the dynamical system. Using the Lyapunov function with the changeable sign, conditions for the regularity of the entire examined dynamical system were given, assuming ...

Controllability of nonlinear fractional Langevin delay systems

open access: yesNonlinear Analysis, 2019
In this paper, we discuss the controllability of fractional Langevin delay dynamical systems represented by the fractional delay differential equations of order 0

Complexity and Dynamical Depth

open access: yesInformation, 2014
We argue that a critical difference distinguishing machines from organisms and computers from brains is not complexity in a structural sense, but a difference in dynamical organization that is not well accounted for by current complexity measures.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Antagonistic interactions can stabilise fixed points in heterogeneous linear dynamical systems

open access: yesSciPost Physics, 2023
We analyse the stability of large, linear dynamical systems of variables that interact through a fully connected random matrix and have inhomogeneous growth rates.
