A fully discrete Calderón calculus for the two-dimensional elastic wave equation
(Elsevier, 2015)
info:eu-repo/semantics/article,
In this paper we present a full discretization of the layer potentials and boundary integral operators for the elastic wave equation on a parametrizable smooth closed curve in the plane. The method can be understood as a ...
Improved accuracy for time-splitting methods for the numerical solution of parabolic equations
(Elsevier, 2015)
info:eu-repo/semantics/article,
In this work, we study time-splitting strategies for the numerical approximation of evolutionary reaction–diffusion problems. In particular, we formulate a family of domain decomposition splitting methods that overcomes ...
Optimized strong stability preserving IMEX Runge-Kutta methods
(2014)
Artículo / Artikulua,
We construct and analyze robust strong stability preserving IMplicit-EXplicit Runge-Kutta (IMEX RK) methods for models of flow with diffusion as they appear in astrophysics and in many other fields where equations with ...
Construction of additive semi-implicit Runge-Kutta methods with low-storage requirements
(Springer US, 2016)
Artículo / Artikulua,
Space discretization of some time-dependent partial differential equations gives rise to systems of
ordinary differential equations in additive form whose terms have different stiffness properties. In these
cases, implicit ...
Implementation of wireless sensor network architecture for interactive shopping carts to enable context-aware commercial areas
(IEEE, 2016)
Artículo / Artikulua,
An interactive shopping cart to enable context
aware environments within large commercial areas is presented.
A wireless sensor network was designed, with specific nodes
embedded within the shopping carts and infrastructure ...
Modified Douglas splitting methods for reaction–diffusion equations
(Springer, 2017)
info:eu-repo/semantics/article,
We present modifications of the second-order Douglas stabilizing corrections method, which is a splitting method based on the implicit trapezoidal rule. Inclusion of an explicit term in a forward Euler way is straightforward, ...
Orthogonal basis for the optical transfer function
(Optical Society of America, 2016)
info:eu-repo/semantics/article,
We propose systems of orthogonal functions qn to represent optical transfer functions (OTF) characterized by including the diffraction-limited OTF as the first basis function q0 OTF perfect. To this end, we apply a powerful ...
Orthogonal basis with a conicoid first mode for shape specification of optical surfaces: reply
(Optical Society of America, 2016)
info:eu-repo/semantics/article,
We present some comments to the paper 'Orthogonal basis with a conicoid first mode for shape specification of optical surfaces: comment'.
IVAN: Intelligent van for the distribution of pharmaceutical drugs
(MDPI, 2012)
Artículo / Artikulua,
This paper describes a telematic system based on an intelligent van which is capable of tracing pharmaceutical drugs over delivery routes from a warehouse to pharmacies, without altering carriers' daily conventional tasks. ...
Order barrier for low-storage DIRK methods with positive weights
(Springer, 2018)
Artículo / Artikulua,
In this paper we study an order barrier for low-storage diagonally implicit Runge-Kutta (DIRK) methods with positive weights. The Butcher matrix for these schemes, that can be implemented with only two memory registers in ...
