On the averaging of differential inclusions with maxima [PDF]

open access: yesMathematica Bohemica, 2023
We apply the averaging method to ordinary differential inclusions with maxima perturbed by a small parameter and illustrate the method by some examples.

Averaging method for ordinary differential inclusions with maxima

open access: yesElectronic Journal of Differential Equations, 2018
We consider ordinary differential inclusions with maxima perturbed by a small parameter and give justification of the method of averaging for this type of inclusions.

Excitation of surface plasmon-polaritons in metal films with double periodic modulation: anomalous optical effects [PDF]

open access: yes, 2007
We perform a thorough theoretical analysis of resonance effects when an arbitrarily polarized plane monochromatic wave is incident onto a double periodically modulated metal film sandwiched by two different transparent media. The proposed theory offers a

A relaxation theorem for a differential inclusion with “maxima” [PDF]

open access: yesAnalele Universitatii "Ovidius" Constanta - Seria Matematica, 2017
Abstract We consider a Cauchy problem associated to a nonconvex differential inclusion with “maxima” and we prove a Filippov type existence result. This result allows to obtain a relaxation theorem for the problem considered.

" Existence of solutions for a class of functional differential inclusions with ""maxima""" [PDF]

open access: yesFixed Point Theory, 2018
This paper is mainly concerned with a boundary value problem associated to a second-order differential inclusion with ``maxima'' term. Based upon suitable fixed point theorems combined with selection theorems, some existence results are established when the multi-valued nonlinear term has convex or non convex values.

Plasmonically Enhanced Reflectance of Heat Radiation from Low-Bandgap Semiconductor Microinclusions [PDF]

open access: yes, 2017
Increased reflectance from the inclusion of highly scattering particles at low volume fractions in an insulating dielectric offers a promising way to reduce radiative thermal losses at high temperatures.

Minimal time control of fed-batch processes with growth functions having several maxima [PDF]

open access: yes, 2010
We address the issue of minimal time optimal control of fedbatch reactor in presence of complex non monotonic kinetics, that can be typically characterized by the combination of two Haldane models. The optimal synthesis may present several singular arcs.

Towards active microfluidics: Interface turbulence in thin liquid films with floating molecular machines [PDF]

open access: yes, 2008
Thin liquid films with floating active protein machines are considered. Cyclic mechanical motions within the machines, representing microscopic swimmers, lead to molecular propulsion forces applied to the air-liquid interface. We show that, when the rate

Sulfate Burial Constraints on the Phanerozoic Sulfur Cycle [PDF]

open access: yes, 2012
The sulfur cycle influences the respiration of sedimentary organic matter, the oxidation state of the atmosphere and oceans, and the composition of seawater.

Transport in polymer-gel composites: Theoretical methodology and response to an electric field

open access: yes, 2006
A theoretical model of electromigrative, diffusive and convectivetransport polymer-gel composites is presented. Bulk properties are derived from the standard electrokinetic model with an impenetrable charged sphere embedded in an electrolyte-saturated ...
