On the Singular Perturbations for Fractional Differential Equation [PDF]

open access: yesThe Scientific World Journal, 2014
The goal of this paper is to examine the possible extension of the singular perturbation differential equation to the concept of fractional order derivative. To achieve this, we presented a review of the concept of fractional calculus. We make use of the

Avionic Air Data Sensors Fault Detection and Isolation by means of Singular Perturbation and Geometric Approach [PDF]

open access: goldSensors, 2017
Singular Perturbations represent an advantageous theory to deal with systems characterized by a two-time scale separation, such as the longitudinal dynamics of aircraft which are called phugoid and short period.

Homotopic approach for turnpike and singularly perturbed optimal control problems [PDF]

open access: yesESAIM: Proceedings and Surveys, 2021
The first aim of this article is to present the link between the turnpike property and the singular perturbations theory: the first one being a particular case of the second one.

Singular Perturbations of Multibrot Set Polynomials

open access: yesUniversal Journal of Mathematics and Applications, 2022
We will give a complete description of the dynamics of the rational map $N_{F_{M_c}}(z)=\frac{3z^4-2z^3+c}{4z^3-3z^2+c}$ where c is a complex parameter. These are rational maps $N_{F_{M_c}}$ arising from Newton's method.

Symmetries and perturbations of time-scale nonshifted singular systems

open access: yesAIP Advances, 2023
In this work, the symmetries and perturbations of time-scale nonshifted singular Lagrangian and singular nonconservative Lagrangian systems are studied. The differential equations of motion are given. The definitions and criteria of the Noether, Lie, and

Inverse Eigenvalue Problems for Singular Rank One Perturbations of a Sturm-Liouville Operator

open access: yesAdvances in Mathematical Physics, 2021
This paper is concerned with the inverse eigenvalue problem for singular rank one perturbations of a Sturm-Liouville operator. We determine uniquely the potential function from the spectra of the Sturm-Liouville operator and its rank one perturbations.

Ensemble singular vectors and their use as additive inflation in EnKF [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2015
Given an ensemble of forecasts, it is possible to determine the leading ensemble singular vector (ESV), that is, the linear combination of the forecasts that, given the choice of the perturbation norm and forecast interval, will maximise the growth of ...

Singular structures in solutions to the Monge-Ampère equation with point masses

open access: yesMathematics in Engineering, 2023
We construct new examples of Monge-Ampère metrics with polyhedral singular structures, motivated by problems related to the optimal transport of point masses and to mirror symmetry.

Numerical and asymptotic flow stability analysis of vortex structures [PDF]

open access: yesE3S Web of Conferences, 2021
Stability problem of an axisymmetric swirling flow of a viscous incompressible fluid with respect to nonaxisymmetric perturbations is considered. The system of ordinary differential equations for the amplitude functions is solved numerically by the Runge-
