Characterization of wireless channel impact on wireless sensor network performance in public transportation buses
(IEEE, 2015)
Artículo / Artikulua,
Wireless communications systems are growing rapidly during the last two decades and they are gaining a significant role for multiple communication tasks within public transportation buses. In this work, the impact of ...
Averaging, reduction and reconstruction in the spatial three-body problem
(2015)
Tesis doctoral / Doktoretza tesia,
El objetivo de esta tesis es el estudio de la dinámica del problema espacial de
tres cuerpos. En particular, se establece la existencia de toros KAM asociados a
diferentes tipos de movimientos. El problema espacial de ...
Analysis of wireless sensor network topology and estimation of optimal network deployment by deterministic radio channel characterization
(MDPI, 2015)
Artículo / Artikulua,
One of the main challenges in the implementation and design of context-aware
scenarios is the adequate deployment strategy for Wireless Sensor Networks (WSNs),
mainly due to the strong dependence of the radiofrequency ...
Holographic acoustic elements for manipulation of levitated objects
(Nature Publishing Group, 2015)
Artículo / Artikulua,
Sound can levitate objects of different sizes and materials through air, water and tissue. This allows us to manipulate cells, liquids, compounds or living things without touching or contaminating them. However, acoustic ...
Zernike-like systems in polygons and polygonal facets
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
Zernike polynomials are commonly used to represent the wavefront phase on circular
optical apertures, since they form a complete and orthonormal basis on the unit disk. In
[Diaz et all, 2014] we introduced a new Zernike ...
Convergent and asymptotic expansions of the Pearcey integral
(Elsevier, 2015)
info:eu-repo/semantics/article,
We consider the Pearcey integral P(x; y) for large values of |x|, x, y ∈ C. We can find
in the literature several convergent or asymptotic expansions in terms of elementary and
special functions, with different levels ...
Convergent and asymptotic expansions of solutions of differential equations with a large parameter: Olver cases II and III
(Rocky Mountain Mathematics Consortium, 2015)
Artículo / Artikulua,
This paper continues the investigation initiated in [Lopez, 2013]. We consider the asymptotic
method designed by F. Olver [Olver, 1974] for linear differential equations of the second
order containing a large (asymptotic) ...
New series expansions of the 3F2 function
(2015)
Artículo / Artikulua,
We can use the power series definition of 3F2(a1, a2, a3; b1, b2; z) to compute this function for
z in the unit disk only. In this paper we obtain new expansions of this function that are convergent
in larger domains. ...
Asymptotic behaviour of the Urbanik semigroup
(Elsevier, 2015)
Artículo / Artikulua,
We revisit the product convolution semigroup of probability densities ec(t); c >
0 on the positive half-line with moments (n!)c and determine the asymptotic
behaviour of ec for large and small t > 0. This shows that (n!)c ...
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 ...
