Self-similarity in a system with short-time delayed feedback [PDF]

, 1999
Using the Poincar\'{e} section technique, we study in detail the dynamical behaviors of delay differential system and find a new type of solutions $S_i$ in short-time delay feedback.

Weighted Time-Delay Estimation-Based Proportional-Integral-Derivative Control for High-Order Time-Delay Nonlinear Systems

IEEE Access
In real-world applications, time delays and uncertain nonlinearities are inevitable and impose significant challenges in modern control systems. The uncertainties commonly include nonlinear backlash-like hysteresis, external disturbances, parameter ...

Delay Estimation from noisy time series

, 1997
We propose here a method to estimate a delay from a time series taking advantage of analysis of random walks with delay. This method is applicable to a time series coming out of a system which is or can be approximated as a linear feedback system with ...

A Lyapunov functional for a system with both lumped and distributed delay

Archives of Control Sciences, 2017
In the paper construction of a Lyapunov functional for time delay system with both lumped and distributed delay is presented. The Lyapunov functional is determined by means of the Lyapunov matrix.

Performance boost of time-delay reservoir computing by non-resonant clock cycle

, 2020
The time-delay-based reservoir computing setup has seen tremendous success in both experiment and simulation. It allows for the construction of large neuromorphic computing systems with only few components.

Output tracking via sliding modes in causal systems with time delay modeled by higher order pade approximations [PDF]

, 2006
Output tracking in a SISO causal uncertain nonlinear system with an output subject to a time delay is considered using sliding mode control. A higher order Pade approximation to a delay function with a known time delay is used to construct a model of a ...

On scattering cross sections and durations near an isolated compound-resonance, distorted by the non-resonant background, in the center-of-mass and laboratory systems

, 2011
During last 20 years there was revealed and published the phenomenon of the appearing of the time advance instead of the time delay at the region of a compound-nucleus resonance, distorted by the non-resonant background (in the center-of-mass (C-) system)

Geometric Scattering in Robotic Telemanipulation [PDF]

, 2002
In this paper, we study the interconnection of two robots, which are modeled as port-controlled Hamiltonian systems through a transmission line with time delay. There will be no analysis of the time delay, but its presence justifies the use of scattering

Time-Delay Observables for Koopman: Theory and Applications [PDF]

SIAM Journal on Applied Dynamical Systems, 2018
Nonlinear dynamical systems are ubiquitous in science and engineering, yet analysis and prediction of these systems remains a challenge. Koopman operator theory circumvents some of these issues by considering the dynamics in the space of observable ...

Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.
