Information Dynamic Correlation of Vibration in Nonlinear Systems

open access: yesEntropy, 2019
In previous studies, information dynamics methods such as Von Neumann entropy and Rényi entropy played an important role in many fields, covering both macroscopic and microscopic studies.

Effect of Various Excitation Conditions on Vibrational Energy in a Multi-Degree-of-Freedom Torsional System with Piecewise-Type Nonlinearities

open access: yesEnergies, 2015
Dynamic behaviors in practical driveline systems for wind turbines or vehicles are inherently affected by multiple nonlinearities such as piecewise-type torsional springs.

The Organization that we make. The Universidad Centroccidental Lisandro Alvarado, sixty years of continuous action

open access: yesÁgora de Heterodoxias, 2022
We are building our reality with our actions. At the Universidad Centroccidental Lisandro Alvarado, have we understood that adverse contexts constitute not only threats, but also opportunities to deploy our creative capacities as a learning organization?

Singular nonlinear H∞ optimal control problem [PDF]

open access: yes, 1996
The theory of nonlinear H∞ of optimal control for affine nonlinear systems is extended to the more general context of singular H∞ optimal control of nonlinear systems using ideas from the linear H∞ theory.

Synergetic synthesis of optimal control laws for nonlinear dynamic objects

open access: yesAdaptivni Sistemi Avtomatičnogo Upravlinnâ, 2023
The nonlinearity of a fairly large class of real technical objects is a significant obstacle in the development of control systems for them. In particular, the synthesis of optimal control laws for nonlinear dynamic objects is a very complex task, which

Estimation of Power System Inertia Using Nonlinear Koopman Modes

open access: yes, 2018
We report a new approach to estimating power system inertia directly from time-series data on power system dynamics. The approach is based on the so-called Koopman Mode Decomposition (KMD) of such dynamic data, which is a nonlinear generalization of ...

Classical solutions to quasilinear parabolic problems with dynamic boundary conditions

open access: yes, 2015
We study linear nonautonomous parabolic systems with dynamic boundary conditions. Next, we apply these results to show a theorem of local existence and uniqueness of a classical solution to a second order quasilinear system with nonlinear dynamic ...

Nonlinear Vibration Control of a High-Dimensional Nonlinear Dynamic System of an Axially-Deploying Elevator Cable

open access: yesMathematics
For the first time, a numerical study is presented to demonstrate the importance of high-dimensional nonlinear dynamic systems of axially-deploying elevator cables in the nonlinear vibration and control of such time-varying-length structures, especially ...

Global Stabilization of Triangular Systems with Time-Delayed Dynamic Input Perturbations

open access: yes, 2018
A control design approach is developed for a general class of uncertain strict-feedback-like nonlinear systems with dynamic uncertain input nonlinearities with time delays. The system structure considered in this paper includes a nominal uncertain strict-

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
