Effect of dipole-quadrupole Robinson mode coupling upon the beam response to radio-frequency phase noise

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2006
In an electron storage ring, coupling between dipole and quadrupole Robinson oscillations modifies the spectrum of longitudinal beam oscillations driven by radio-frequency (rf) generator phase noise. In addition to the main peak at the resonant frequency

Levels and sublevels of composition algebras over p-adic function fields [PDF]

open access: yes, 2008
In [O'S], the level and sublevel of composition algebras are studied, wherein these quantities are determined for those algebras defined over local fields.

Robust MFC anti-windup scheme for LTI systems with norm-bounded uncertainty

open access: yesScientific Reports, 2021
On the basic of the fact that all signals in the practical system are always bounded, this paper proposes a 4-degree-of-freedom (DoF) anti-windup scheme for saturated systems with parametric uncertainty. A fairly straightforward tuning rule is introduced

Packed bed absorption column: Hydrodynamics and mass transfer [PDF]

open access: yesActa Periodica Technologica, 2019
This paper presents the results of the determination of the hydrodynamic characteristics and mass transfer in the pilot plate absorption column. The experimental values of the pressure drop in the countercurrent flow of air and water through the

UPAFuzzySystems: A Python Library for Control and Simulation with Fuzzy Inference Systems

open access: yesMachines, 2023
The main goal of control theory is input tracking or system stabilization. Different feedback-computed controlled systems exist in this area, from deterministic to soft methods.

A transfer function approach to transient propagation in media with a quadratic frequency dependence of attenuation coefficient [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1986
The propagation of short acoustical pulses in lossy media is presented as a time-varying transfer function (or spatial filter) that acts on the spatial spectrum of the source excitation. The source is a planar source of arbitrary (but separable) spatial and temporal dependence mounted in a rigid baffle.

A NOTE ON COMONOTONICITY AND POSITIVITY OF THE CONTROL COMPONENTS OF DECOUPLED QUADRATIC FBSDE [PDF]

open access: yes, 2013
In this note we are concerned with the solution of Forward-Backward Stochastic Differential Equations (FBSDE) with drivers that grow quadratically in the control component (quadratic growth FBSDE or qgFBSDE).

Influence of quadratic thermal radiation and activation energy impacts over oblique stagnation point hybrid nanofluid flow across a cylinder

open access: yesCase Studies in Thermal Engineering
Quadratic thermal radiation is a fundamental term within the field of radiative heat transfer, which pertains to the interaction of thermal radiation. It encompasses a quadratic correlation between temperature and radiative qualities.

On the second order effect of the springing response of large blunt ship

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2015
The springing response of a large blunt ship was considered to be influenced by a second order interaction between the incoming irregular wave and the blunt geometry of the forebody of the ship.

Structured interpolation for multivariate transfer functions of quadratic-bilinear systems

open access: yesAdvances in Computational Mathematics
AbstractHigh-dimensional/high-fidelity nonlinear dynamical systems appear naturally when the goal is to accurately model real-world phenomena. Many physical properties are thereby encoded in the internal differential structure of these resulting large-scale nonlinear systems.
