Difference equations with impulses [PDF]

open access: yesOpuscula Mathematica, 2019
Difference equations with impulses are studied focussing on the existence of periodic or bounded orbits, asymptotic behavior and chaos. So impulses are used to control the dynamics of the autonomous difference equations.

A Devil under the Guise of a Good Conscience

open access: yesLabyrinth: An International Journal for Philosophy, Value Theory and Sociocultural Hermeneutics, 2021
Buried within Fyodor Dostoevsky's works are glimpses of corrupt individuals who rise to the fore every now and then. Without these occasional revelations, not many would notice how diabolical an ordinary person really is.

Impulse Oscillometry

open access: yesAdvances in Respiratory Medicine, 2019
Pulmonary function testing involves a battery of tests from the simple pulse oximetry to the cardiopulmonary exercise testing. Impulse oscillometry (IOS) is one of the newly described pulmonary function tests. It is based on the old principle of forced oscillatory technique modified and refined as per research and advances. It involves the use of sound

Scalar linear impulsive Riemann-Liouville fractional differential equations with constant delay-explicit solutions and finite time stability

open access: yesDemonstratio Mathematica, 2020
Riemann-Liouville fractional differential equations with a constant delay and impulses are studied in this article. The following two cases are considered: the case when the lower limit of the fractional derivative is fixed on the whole interval of ...

Impulsive Controllers Design for the Practical Stability Analysis of Gene Regulatory Networks with Distributed Delays

open access: yesFractal and Fractional, 2023
This paper studies gene regulatory networks (GRNs) with distributed delays. The essential concept of practical stability of the genes is introduced. We investigate the problems of practical stability and global practical exponential stability of the GRN ...

Controlabilidad de ecuaciones diferenciales retardadas semilineales impulsivas con retardo infinito y condiciones no locales

open access: yesNOVASINERGIA, 2022
In this paper, we prove the exact controllability of semilinear retarded equations with infinity delay, impulses and nonlocal conditions; proving the conjecture that the controllability is preserve under the influence of

Stability of Stochastic Delay Differential Systems With Variable Impulses Due to Logic Choice

open access: yesIEEE Access, 2021
This paper is concerned with stability problems of stochastic delay differential systems with variable impulses due to logic choice. Firstly, a class of variable impulses due to logic choice is introduced in this paper which is more general than the ...

On the fractional differential equations with not instantaneous impulses

open access: yesOpen Physics, 2016
Based on some previous works, an equivalent equations is obtained for the differential equations of fractional-orderq ∈(1, 2) with non-instantaneous impulses, which shows that there exists the general solution for this impulsive fractional-order systems.

Contact forces between roller and cage pocket in cylindrical roller bearings (Consideration based on dynamic behavior between roller and cage)

open access: yesNihon Kikai Gakkai ronbunshu, 2022
When rolling bearings are used under light loads and high rotational speeds, their life may be determined by cage wear rather than raceway flaking. Under these operating conditions, the life and reliability of the bearings can be improved by reducing ...
