Observations of Shock Waves in Cloud Cavitation [PDF]

, 1998
This paper describes an investigation of the dynamics and acoustics of cloud cavitation, the structures which are often formed by the periodic breakup and collapse of a sheet or vortex cavity.

ExistenceofMildSolutionsforaClassofSecond-order StochasticEvolutionEquationswithImpulses

Journal of Harbin University of Science and Technology, 2023
The existence of mild solutions for a class of second-order non-autonomous stochastic evolution equations with instantaneous impulses is studied in Hilbert space. By using Sadovskii ′ s fixed point theorem and the theory

Momentum Transfer by Laser Ablation of Irregularly Shaped Space Debris [PDF]

, 2010
Proposals for ground-based laser remediation of space debris rely on the creation of appropriately directed ablation-driven impulses to either divert the fragment or drive it into an orbit with a perigee allowing atmospheric capture.

On a delayed epidemic model with non-instantaneous impulses

Communications on Pure & Applied Analysis, 2020
In the traditional SIR model a new group into the population is added. It is the group of individuals that carries the disease but does not show symptoms. It is studied the case that the infectious diseases are controlled by a pulse vaccination strategy but in a non-instantaneous way.

Variational approach to non-instantaneous impulsive nonlinear differential equations

The Journal of Nonlinear Sciences and Applications, 2017
Summary: In this paper, a class of nonlinear differential equations with non-instantaneous impulses are considered. By using variational methods and critical point theory, a criterion is obtained to guarantee that the non-instantaneous impulsive problem has at least two distinct nonzero bounded weak solutions.

Qualitative Analysis and Applications of Fractional Stochastic Systems with Non-Instantaneous Impulses

Mathematics
Fractional stochastic differential Equations (FSDEs) with time delays and non-instantaneous impulses describe dynamical systems whose evolution relies not only on their current state but also on their historical context, random fluctuations, and ...

Design of maneuvers based on new normal form approximations: The case study of the CPRTBP

, 2014
In this work, we study the motions in the region around the equilateral Lagrangian equilibrium points L4 and L5, in the framework of the Circular Planar Restricted Three-Body Problem (hereafter, CPRTBP).
