A Differential Algebraic Method to Approximate Nonsmooth Mechanical Systems by Ordinary Differential Equations

open access: yesJournal of Applied Mathematics, 2013
Nonsmooth mechanical systems, which are mechanical systems involving dry friction and rigid unilateral contact, are usually described as differential inclusions (DIs), that is, differential equations involving discontinuities.

Coherent Amplification of Optical Pulses in Metamaterials [PDF]

open access: yes, 2009
In this paper we theoretically study propagation of steady state ultrashort pulse in dissipative medium. We considered two cases (i) medium consists of lossy metallic nanostructures embedded into a gain material and (ii) the gain material is embedded ...

Stability radius of second order linear structured differential inclusions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
For arbitrary second order square matrices $A, B, C$; $A$ Hurwitz stable, the minimum positive value $R$ for which the differential inclusion $$\dot{x}\in F_{R}(x):=\{(A+B\Delta C)x, \ \Delta \in \mathbb{R}^{2\times 2},\ \|\Delta \| \le R \}$$ fails to ...

Convergence of nonautonomous multivalued problems with large diffusion to ordinary differential inclusions

open access: yesCommunications on Pure & Applied Analysis, 2020
The authors consider families of non-autonomous partial differential inclusions (multivalued) with \(p\)-Laplacians with variable coefficients as differential operators, large diffusions and driven by nonlinearities of Heaviside type, i.e., corresponding to discontinuous nonlinear terms and with Neumann boundary conditions.

A Multi-Scale, Semi-Analytical Model for Transient Heat Transfer in a Nano-Composite Containing Spherical Inclusions

open access: yesEurasian Chemico-Technological Journal, 2019
This paper presents a semi-analytical model for transient heat conduction in a composite material reinforced with small spherical inclusions. Essential to the derivation of the model is the assumption that the size of the inclusions is much smaller than ...

Existence of weak solutions to stochastic evolution inclusions [PDF]

open access: yes, 2004
We consider the Cauchy problem for a semilinear stochastic differential inclusion in a Hilbert space. The linear operator generates a strongly continuous semigroup and the nonlinear term is multivalued and satisfies a condition which is more heneral than

Differential inclusions, non-absolutely convergent integrals and the first theorem of complex analysis [PDF]

open access: yes, 2013
In the theory of complex valued functions of a complex variable arguably the first striking theorem is that pointwise differentiability implies $C^{\infty}$ regularity.

Characterizations of safety in hybrid inclusions via barrier functions [PDF]

open access: yes, 2019
This paper investigates characterizations of safety in terms of barrier functions for hybrid systems modeled by hybrid inclusions. After introducing an adequate definition of safety for hybrid inclusions, sufficient conditions using continuously ...
