Holographic acoustic elements for manipulating levitating particles. Applications in human-computer interaction
(2016)
Tesis doctoral / Doktoretza tesia,
En esta tesis doctoral demostramos simultáneamente atrapamiento 3D, traslación y rotación de las partículas utilizando dispositivos de una sola cara. Esto se logra mediante el ajuste de manera óptima los retardos de fase ...
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 ...
An easy to deploy street light control system based on wireless communication and LED technology
(MDPI, 2013)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents an intelligent streetlight management system based on LED lamps, designed to facilitate its deployment in existing facilities. The proposed approach, which is based on wireless communication technologies, ...
Ubiquitous connected train based on train-to-ground and intra-wagon communications capable of providing on trip customized digital services for passengers
(MDPI, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
During the last years, the application of different wireless technologies has been explored in order to enable Internet connectivity from vehicles. In addition, the widespread adoption of smartphones by citizens represents ...
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 ...
Singular reduction of resonant Hamiltonians
(IOP PublishingLondon Mathematical Society, 2018)
Artículo / Artikulua,
We investigate the dynamics of resonant Hamiltonians with n degrees of freedom to which we attach a small perturbation. Our study is based on the geometric interpretation of singular reduction theory. The flow of the ...
New asymptotic expansion and error bound for Stirling formula of reciprocal Gamma function
(Ele-Math, 2018)
Artículo / Artikulua,
Studying the problem about if certain probability measures are determinate by its moments
[4, 8, 10] is useful to know the asymptotic behavior of the probability densities for large
values of argument. This requires, ...
The use of two-point Taylor expansions in singular one-dimensional boundary value problems I
(Elsevier, 2018)
info:eu-repo/semantics/article,
We consider the second-order linear differential equation (x + 1)y′′ + f(x)y′ + g(x)y = h(x) in
the interval (−1, 1) with initial conditions or boundary conditions (Dirichlet, Neumann or mixed
Dirichlet-Neumann). The ...
Asymptotic and convergent expansions for solutions of third-order linear differential equations with a large parameter
(Shanghai Normal UniversityWilmington Scientific Publisher, 2018)
info:eu-repo/semantics/article,
In previous papers [6–8,10], we derived convergent and asymptotic
expansions of solutions of second order linear differential equations with a
large parameter. In those papers we generalized and developed special cases
not ...
Convergent and asymptotic methods for second-order difference equations with a large parameter
(Springer, 2018)
info:eu-repo/semantics/article,
We consider the second-order linear difference equation y(n+2)−2ay(n+1)−Λ2y(n)=g(n)y(n)+f(n)y(n+1) , where Λ is a large complex parameter, a≥0 and g and f are sequences of complex numbers. Two methods are proposed to find ...
