(Frontiers Media, 2020)Existing mathematical models for the glucose-insulin (G-I) dynamics often involve variables that are not susceptible to direct measurement. Standard clinical tests for measuring G-I levels for diagnosing potential diseases ...
-
(2003)The L2- and H1-approximate controllability and homogenization of a semilinear elliptic boundary-value problem is studied in this paper. The principal term of the state equation has rapidly oscillating coefficients and ...
-
(Texas State University, 2017)In this article, we study the approximate controllability and home-genization results of a semi-linear elliptic problem with Robin boundary condition in a periodically perforated domain. We prove the existence of minimal ...
-
(ELSEVIER, 2010)In this paper we shall study a fractional integral equation in an arbitrary Banach space X. We used the analytic semigroups theory of linear operators and the fixed point method to establish the existence and uniqueness ...
-
(1994)Given a parametrised measure and a family of continuous functions (<pn), we construct a sequence of functions (uk) such that, as fc-> co, the functions fn(uk) converge to the corresponding moments of the measure, in the ...
-
(1998-06)An asymptotic study of two spectral models which appear in uid{solid vibrations is presented in this paper. These two models are derived under the assumption that the uid is slightly compressible or viscous, respectively. ...
-
(2002)The classical problem of homogenization of elliptic operators with periodically oscillating coefficients is revisited in this paper. As is well known, the homogenization process in a classical framework is concerned with ...
-
(IOS PRESS, 2005-01)The classical problem of homogenization deals with elliptic operators in periodically oscillating media of small period epsilon>0 and the asymptotic behavior of solution u(epsilon) of boundary value problems associated ...
-
(2005)We consider a periodically heterogeneous and perforated medium filling an open domain of RN . Assuming that the size of the periodicity of the structure and of the holes is O(ε), we study the asymptotic behavior, as ε ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 1998-02)We consider a second-order elliptic equation in a bounded periodic heterogeneous medium and study the asymptotic behavior of its spectrum, as the structure period goes to zero. We use a new method of Bloch wave homogenization ...
-
(SIAM PUBLICATIONS, 1998-03)This paper is devoted to the asymptotic analysis of the spectrum of a mathematical model that describes the vibrations of a coupled fluid-solid periodic structure. In a previous work [Arch. Rational Mech. Anal., 135 (1996), ...

(Universidad de Chile, 2015)Se realiza un análisis teórico de estabilidad, acotamiento, convergencia y propiedades de sistemas de orden no entero con la elección de derivada no entera según Caputo. En las deducciones se emplea fundamentalmente el ...
-
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2008-08)In this Note we investigate the problem of the detection of a moving obstacle in a perfect fluid occupying a bounded domain in R-2 from the measurement of the velocity of the fluid on one part of the boundary. We show that ...
-
(2010)In this paper, we consider a moving rigid solid immersed in a potential fluid. The fluid–solid system fills the whole two-dimensional space and the fluid is assumed to be at rest at infinity. Our aim is to study the ...
-
(2003)In the book by Hornung, Chap. 6, the author proposes a homogenization strategy for the e ective behavior of some chemical processes involving adsorption and reactions arising in porous media. Rigorous proofs of the ...
-
(2002)We study the existence and uniqueness of strong solutions for the equations of non-homogeneous asymmetric uids. We use an iterative approach and we prove that the approximate solutions constructed by this method converge ...

(Universidad de Chile, 2007)El presente trabajo de título presenta el estudio en conjunto del Centro de Modelamiento Matemático (CMM) y el Instituto en Minería y Metalurgia (IM2) para estimar el comportamiento del material particulado acoplado con ...
-
(Universidad de Chile, 2016)El presente trabajo muestra un estudio desde los fundamentos de resonancia magnética, hasta el desarrollo de un problema que puede presentar aplicaciones en estudios en medicina. Se expone el proceso físico de resonancia ...
-
(Universidad de Chile, 2015)Los ensayos realizados en un reómetro rotacional tienen como límite superior de medición la velocidad angular crítica para asegurar un flujo axisimétrico. Para velocidades mayores a ésta, el flujo deja de ser concéntrico ...
