Algoritmes de Beamforming computacionalment eficients per a aplicacions d'audio

Lorente Giner, Jorge (Universitat Politècnica de València, 2013-07-08)

[ES] Un array de micófonos es un conjunto de micrófonos distribuidos en el espacio formando un determinado patrón. Desde hace unas décadas se han estudiado y desarrollado algorítmos de beamforming para arrays de micrófonos ...
An efficient Steffensen-like iterative method with memory

Cordero Barbero, Alicia; Lotfi, T.; Khoshandi, A.; Torregrosa Sánchez, Juan Ramón (Société des Sciences Mathématiques de Roumanie, 2015)

[EN] Some methods with memory for solving nonlinear equations are designed from known methods without memory. We increase the convergence order from 4 to 6 by using a free parameter accelerator by Newton's interpolatory ...
Avoiding strange attractors in efficient parametric families of iterative methods for solving nonlinear problems

Cordero Barbero, Alicia; Giménez-Palacios, Ivan; Torregrosa Sánchez, Juan Ramón (Elsevier, 2019-03)

[EN] Searching zeros of nonlinear functions often employs iterative procedures. In this paper, we construct several families of iterative methods with memory from one without memory, that is, we have increased the order ...
Domain of existence for the solution of some IVP's and BVP's by using an efficient ninth-order iterative method

Cevallos, Fabricio; Hueso, José L.; Martínez Molada, Eulalia; Howk, Cory L. (John Wiley & Sons, 2020-09-30)

[EN] In this paper, we consider the problem of solving initial value problems and boundary value problems through the point of view of its continuous form. It is well known that in most cases these types of problems are ...
Fast exact variable order affine projection algorithm

Ferrer Contreras, Miguel; Gonzalez, Alberto; Diego Antón, María de; Piñero Sipán, María Gemma (Elsevier, 2012-09)

Variable order affine projection algorithms have been recently presented to be used when not only the convergence speed of the algorithm has to be adjusted but also its computational cost and its final residual error. These ...
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 ...
Modified Potra-Pták multi-step schemes with accelerated order of convergence for solving sistems of nonlinear equations

Arora, Himani; Torregrosa Sánchez, Juan Ramón; Cordero Barbero, Alicia (MDPI AG, 2019-03)

[EN] In this study, an iterative scheme of sixth order of convergence for solving systems of nonlinear equations is presented. The scheme is composed of three steps, of which the first two steps are that of third order ...
New efficient methods for solving nonlinear systems of equations with arbitrary even order

Abbasbandy, Saeid; Bakhtiari, Parisa; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Lotfi, Taher (Elsevier, 2016-09-05)

In 2011, Khattri and Abbasbandy developed an optimal two-step Jarratt-like method for approximating simple roots of a nonlinear equation. We develop their method for solving nonlinear systems of equations. The main feature ...
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 ...
Real-time energy optimization of irrigation scheduling by parallel multi-objective genetic algorithms

Alonso-Campos, Joan-Carles; Jiménez Bello, Miguel Angel; Martínez Alzamora, Fernando (Elsevier, 2020-01-20)

[EN] The present work is motivated by the need to reduce the energy costs arising from the pressure demands of drip and sprinkling irrigation, compounded by the increase in the energy price in recent years. Researchers ...
