    Efficient high-order methods based on golden ratio for nonlinear system 
    Cordero Barbero, Alicia; Hueso Pagoaga, José Luís; Martínez Molada, Eulalia; Torregrosa Sánchez, Juan Ramón (Elsevier, 2011-01-01)
    We derive new iterative methods with order of convergence four or higher, for solving nonlinear systems, by composing iteratively golden ratio methods with a modified Newton's method. We use different efficiency indices ...

    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. ...

    Increasing the convergence order of an iterative method for nonlinear systems 
    Cordero Barbero, Alicia; Hueso Pagoaga, José Luís; Martínez Molada, Eulalia; Torregrosa Sánchez, Juan Ramón (Elsevier, 2012-12)
    In this work we introduce a technique for solving nonlinear systems that improves the order of convergence of any given iterative method which uses the Newton iteration as a predictor. The main idea is to compose a given ...

    Raman scattering study of bulk and nanocrystalline PbMoO4 at high pressures 
    Vilaplana Cerda, Rosario Isabel; Gomis Hilario, Oscar; Manjón Herrera, Francisco Javier; Rodríguez-Hernández, P.; Muñoz, Alfonso; Errandonea, Daniel; Achary, S.N.; Tyagi, A.K. (American Institute of Physics (AIP), 2012-11-21)
    High-pressure Raman scattering measurements have been performed in wulfenite (PbMoO4) for both bulk and nanocrystalline powders up to 22 GPa. Our Raman scattering measurements evidence the phase transition from the tetragonal ...

    Sound transmission through plates perforated with two periodic subwavelength hole arrays 
    Estrada, Héctor; Gómez Lozano, Vicente; Uris Martínez, Antonio; Candelas Valiente, Pilar; Belmar Ibáñez, Francisco; Meseguer Rico, Francisco Javier (IOP Publishing: Hybrid Open Access, 2011-03)
    Theoretical results on sound transmission through plates perforated with compound periodic hole arrays are presented. Calculations are obtained by means of a model under the rigid-solid assumption, which is thoroughly ...
