A class of Steffensen type methods with optimal order of convergente

Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón (Elsevier, 2011-06-01)

In this paper, a family of Steffensen type methods of fourth-order convergence for solving nonlinear smooth equations is suggested. In the proposed methods, a linear combination of divided differences is used to get a ...
Analysis of equivalent anisotropy arising from dual isotropic layers of acoustic media

Cai, Liang-Wu; Sánchez-Dehesa Moreno-Cid, José (Acoustical Society of America, 2012-10)

The equivalence between a single mass-anisotropic layer and two isotropic layers is analyzed by studying two systems: one consists of an anisotropic layer sandwiched between two arbitrarily chosen isotropic media; and the ...
Asymptotic statistical analysis for model-based control design strategies

Esparza Peidro, Alicia; Agüero, Juan C.; Rojas, Cristian R.; Godoy, Boris I. (International Federation of Automatic Control, 2011)

In this paper, we generalize existing fundamental limitations on the accuracy of the estimation of dynamic models. In addition, we study the large sample statistical behavior of different estimation-based controller design ...
Exact and approximated calculation of the cycle service level in a continuous review policy

Cardós, Manuel; Babiloni, Eugenia (ELSEVIER SCIENCE BV, 2011)

[EN] The paper proposes a method to compute the exact cycle service level for (s, Q) continuous review policy in the presence of undershoots and discrete demand in the discrete time domain. Prior to this, it is necessary ...
Improvement on the bound of Hermite matrix polynomials

Defez Candel, Emilio; Tung, Michael Ming-Sha; Sastre, Jorge (Elsevier, 2011-04-15)

In this paper, we introduce an improved bound on the 2-norm of Hermite matrix polynomials. As a consequence, this estimate enables us to present and prove a matrix version of the Riemann-Lebesgue lemma for Fourier transforms. ...
Multiple scattering formulation of two-dimensional acoustic and electromagnetic metamaterials

Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (IOP Publishing: Open Access Journals, 2011-09-09)

A multiple scattering formulation of two-dimensional (2D) acoustic metamaterials is presented. This approach is comprehensive and can lead to frequency-dependent effective parameters (scalar bulk modulus and tensorial mass ...
New efficient numerical methods to describe the heat transfer in a solid medium

Ponsoda Miralles, Enrique; Blanes Zamora, Sergio; Bader, Philipp (Elsevier, 2011-10)

The analysis of heat conduction through a solid with heat generation leads to a linear matrix differential equation with separated boundary conditions. We present a symmetric second order exponential integrator for the ...
Robustness to Algorithmic Singularities and Sensitivity in Computational Kinematics

Gracia Calandin, Luis Ignacio; Angeles, J. (SAGE Publications, 2011)

A robust approach to computational kinematics intended to cope with algorithmic singularities is introduced in this article. The approach is based on the reduction of the original system of equations to a subsystem of ...
Time-averaging and exponential integrators for non-homogeneous linear IVPs and BVPs

Blanes Zamora, Sergio; Ponsoda Miralles, Enrique (Elsevier, 2012-08)

We consider time-averaging methods based on the Magnus series expansion jointly with exponential integrators for the numerical integration of general linear non-homogeneous differential equations. The schemes can be ...
Using the GSVD and the lifting technique to find {P; k+ 1} reflexive and anti-reflexive solutions of AXB = C

Herrero Debón, Alicia; Thome, Néstor (Elsevier, 2011-07)

The generalized singular value decomposition (GSVD) and the lifting technique combined with the Kronecker product are exploited to find reflexive and anti-reflexive (with respect to a generalized k+1-reflection matrix P) ...
