Ultrafast optical generation of coherent phonons in CdTe1-xSex quantum dots

open access: yes, 2003
We report on the impulsive generation of coherent optical phonons in CdTe0.68Se0.32 nanocrystallites embedded in a glass matrix. Pump probe experiments using femtosecond laser pulses were performed by tuning the laser central energy to resonate with the ...

Impulsive evolution inclusions with state-dependent delay and multivalued jumps

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper we prove the existence of a mild solution for a class of impulsive semilinear evolution differential inclusions with state-dependent delay and multivalued jumps in a Banach space.

Non-smooth modelling of electrical systems using the flux approach [PDF]

open access: yes, 2018
The non-smooth modelling of electrical systems, which allows for idealised switching components, is described using the flux approach. The formulations and assumptions used for non-smooth mechanical systems are adopted for electrical systems using the ...

On reduction of differential inclusions and Lyapunov stability

open access: yes, 2019
In this paper, locally Lipschitz, regular functions are utilized to identify and remove infeasible directions from set-valued maps that define differential inclusions.

Filippov's theorem for impulsive differential inclusions with fractional order

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
In this paper, we present an impulsive version of Filippov's Theorem for fractional differential inclusions of the form: $$ \begin{array}{rlll} D^{\alpha}_*y(t) &\in& F(t,y(t)), &\hbox{ a.e. } \, t\in J\backslash \{t_{1},\ldots,t_{m}\},\ \alpha\in(1,2]

Consistent Approximations to Impulsive Optimal Control Problems

open access: yes, 2016
We analyse the theory of consistent approximations given by Polak and we use it in an impulsive optimal control problem. We reparametrize the original system and build consistent approximations for this new reparametrized problem.

Impulsive fractional differential inclusions with flux boundary conditions

open access: yesFilomat, 2017
In this work we investigate some existence results for solutions of a boundary value problem for impulsive fractional differential inclusions supplemented with fractional flux boundary conditions by applying Bohnenblust-Karlin?s fixed point theorem for multivalued maps.
