Optimization and design of wireless systems for the implementation of context aware scenarios in railway passenger vehicles
(IEEE, 2017)
Artículo / Artikulua,
In this paper, intra-wagon wireless communication
performance is analyzed, in order to account for inherent
scenario complexity in the deployment phase of wireless systems
toward the implementation of a context-aware ...
Spatial characterization of radio propagation channel in urban vehicle-to-infrastructure environments to support WSNs deployment
(MDPI, 2017)
Artículo / Artikulua,
Vehicular ad hoc Networks (VANETs) enable vehicles to communicate with each other as well as with roadside units (RSUs). Although there is a significant research effort in radio channel modeling focused on vehicle-to-vehicle ...
Challenges in wireless system integration as enablers for indoor context aware environments
(MDPI, 2017)
Artículo / Artikulua,
The advent of fully interactive environments within Smart Cities and Smart Regions requires the use of multiple wireless systems. In the case of user-device interaction, which finds multiple applications such as Ambient ...
A simplification of the stationary phase method: application to the Anger and Weber functions
(Kent State UniversityJohann Radon Institute (RICAM), 2017)
info:eu-repo/semantics/article,
The main difficulty in the practical use of the stationary phase method in asymptotic expansions of
integrals is originated by a change of variables. The coefficients of the asymptotic expansion are the coefficients of
the ...
Convergent expansions of the incomplete gamma functions in terms of elementary functions
(World Scientific Publishing, 2017)
info:eu-repo/semantics/article,
We consider the incomplete gamma function γ(a,z) for Ra>0 and z∈C. We derive several convergent expansions of z−aγ(a,z) in terms of exponentials and rational functions of z that hold uniformly in z with Rz bounded from ...
Analytic formulas for the evaluation of the Pearcey integral
(American Mathematical Society, 2017)
info:eu-repo/semantics/article,
We can find in the literature several convergent and/or asymptotic
expansions of the Pearcey integral P(x, y) in different regions of the complex
variables x and y, but they do not cover the whole complex x and y ...
From start to finish: teenagers on the autism spectrum developing their own collaborative game
(Emerald, 2017)
info:eu-repo/semantics/article,
Purpose: The purpose of this paper is to investigate how teenagers on the autism spectrum respond to their involvement in the creation of a collaborative game, meeting the curriculum requirements in programming at secondary ...
Representations of hypergeometric functions for arbitrary parameter values and their use
(2017)
Artículo / Artikulua,
Integral representations of hypergeometric functions proved to be
a very useful tool for studying their properties. The purpose of this paper is
twofold. First, we extend the known representations to arbitrary values of ...
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, ...
