Dynamics analysis of a nonlinear controlled predator–prey model with complex Poincaré map [PDF]

open access: yesNonlinear Analysis
In this paper, we propose a class of predator–prey models with nonlinear state-dependent feedback control in the saturated state. The nonlinear state impulse control leads to a diversity of pulse and phase sets such that the Poincaré map built on the ...

Poincaré Plots in Analysis of Selected Biomedical Signals [PDF]

open access: yesStudies in Logic, Grammar and Rhetoric, 2013
Poincaré plot is a return map which can help perform graphical analysis of data. We can also fit an ellipse to the plot shape by determining descriptors SD1, SD2 and SD1/SD2 ratio to study the data quantitatively.

Constructing the Second Order Poincaré Map Based on the Hopf-Zero Unfolding Method [PDF]

open access: yesAbstract and Applied Analysis, 2013
We investigate the Shilnikov sense homoclinicity in a 3D system and consider the dynamical behaviors in vicinity of the principal homoclinic orbit emerging from a third order simplified system.

Poincaré Filter for Trajectory Design in Multi-body Regime [PDF]

open access: yes, 2022
The Poincaré map and filter with an optimization algorithm for trajectory design in a multi-body regime is presented. The algorithm is capable of designing groups of trajectories that abide by the predetermined mission and spacecraft parameters.

Variations of the Poincaré Map [PDF]

open access: yes, 2012
.Nogueira, in 1995, presented a study of the Poincaré map and the related Parry–Daniels map. In this note some variants of this algorithm are presented which seem to have quite different ergodic behavior.

Juggling a Devil-Stick: Hybrid Orbit Stabilization using the Impulse Controlled Poincaré Map [PDF]

open access: yes, 2022
The control design for juggling a devil-stick between two symmetric configurations is proposed. Impulsive forces are applied to the devil-stick at the two configurations; and impulse of the force and its point of application are modeled as the control ...

Multichannel quantum defect theory: a quantum Poincaré map [PDF]

open access: yes, 2000
International audienceThe multichannel quantum defect theory (MQDT) can be reinterpreted as a quantum Poincaré map in representation of angular momentum.

Heart Rate Variability Features as Predictors of Intermittent Theta‐Burst Stimulation Response in Posttraumatic Stress Disorder

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Background Posttraumatic stress disorder (PTSD) is associated with autonomic dysfunction as indicated by deficits in the sympathetic and parasympathetic nervous systems. These abnormalities are expressed as elevated heart rate and reduced heart rate variability (HRV), respectively.

Extended Poincaré model and non‐linear analysis of permanent‐magnet synchronous motor scalar drive system

open access: yesIET Power Electronics, 2022
In this paper, bifurcation diagrams, modified Poincaré map and Lyapunov exponents characteristic are developed for studying non‐linear phenomenon in dynamics of permanent‐magnet synchronous machine scalar drive systems (PMSMSDS).

The Poincaré Map in Mixed Exterior Algebra [PDF]

open access: yes, 1983
The Poincaré map of mixed exterior algebra generalizes the Hodge star operator and it plays a central rôle in the proofs of many classical identities of linear algebra. The principal purpose of this paper is to derive a new formula for it.
