Deflecting small asteroids using laser ablation : Deep space navigation and asteroid orbit control for LightTouch2 Mission [PDF]

open access: yes, 2013
This paper presents a low-cost, low mass, mission design to successfully intercept and deflect a small and faint, 4 m in diameter asteroid. Intended to be launched after 2025, the laser-ablating mission, LightTouch2 will be used to deflect the orbit of ...

Variational approach to non-instantaneous impulsive differential equations with $ p $-Laplacian operator

open access: yesAIMS Mathematics, 2022
<abstract><p>In this paper, we consider the existence, multiplicity and nonexistence of solutions for a class of $ p $-Laplacian differential equations with non-instantaneous impulses. By using variational methods and critical point theory, we obtain that the impulsive problem has at least one nontrivial solution, at least two nontrivial ...

On Fractional Integro-differential Equations with State-Dependent Delay and Non-Instantaneous Impulses [PDF]

open access: yesCubo (Temuco), 2019
Summary: In this paper, we prove the existence of mild solution of the fractional integro-differential equations with state-dependent delay with not instantaneous impulses. The existence results are obtained under the conditions on the Kuratowski's measure of noncompactness. An example is also given to illustrate the results.

Human behaviors: a threat for mosquito control?

open access: yes, 2015
Community involvement and the preventive behavior of households are considered to be at the heart of vector-control strategies. In this work, we consider a simple theoretical model that enables us to take into account human behaviors that may interfere ...

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

open access: yesMathematics
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 ...

Tree-Grass interactions dynamics and Pulse Fires: mathematical and numerical studies

open access: yes, 2015
Savannas are dynamical systems where grasses and trees can either dominate or coexist. Fires are known to be central in the functioning of the savanna biome though their characteristics are expected to vary along the rainfall gradients as observed in Sub-

A survey about framing the bases of Impulsive Mechanics of constrained systems into a jet-bundle geometric context

open access: yes, 2018
We illustrate how the different kinds of constraints acting on an impulsive mechanical system can be clearly described in the geometric setup given by the configuration space--time bundle $\pi_t:\mathcal{M} \to \mathbb{E}$ and its first jet extension ...

The Impulsive Neutral Integro-Differential Equations with Infinite Delay and Non-Instantaneous Impulses

open access: yesInternational Journal of Engineering & Technology, 2018
In this manuscript, we work to accomplish the Krasnoselskii's fixed point theorem to analyze the existence results for an impulsive neutral integro-differential equations  with infinite delay and non-instantaneous impulses in Banach spaces. By deploying the fixed point theorem with semigroup theory, we developed the coveted outcomes.
