Towards social paradigms for mobile context-aware computing in smart cities
(AISTI (Associaçao Ibérica de Sistemas e Tecnologias de Informaçao), 2016)
Mobile context-aware computing is an essential component of the smart cities infrastructure. Attempts were made to develop a model that can effectively represent a system in device to support context-aware behavior. ...
Desarrollo de productos avanzados para la misión SEOSAT/Ingenio
(Asociación Española de Teledetección, 2016)
SEOSAT/Ingenio es la futura misión española de observación de la Tierra en el óptico en alta resolución espacial. Mientras que los productos de imagen a Nivel 1, radiancias geo-referenciadas a nivel de sensor, se encuentran ...
Fabrication of gold nanoparticles in Therminol VP-1 by laser ablation and fragmentation with fs pulses
(IOP Science, 2014-10-22)
This letter reports on a physical method to produce highly pure, size-controlled and well-dispersed spherical gold nanoparticles (NPs) in Therminol VP-1 by pulsed laser ablation in liquids (PLAL) using a 30 fs Ti:Sapphire ...
Downstream Services for Rice Crop Monitoring in Europe: From Regional to Local Scale
(Institute of Electrical and Electronics Engineers (IEEE), 2017-04)
The ERMES agromonitoring system for rice cultivations integrates EO data at different resolutions, crop models, and user-provided in situ data in a unified system, which drives two operational downstream services for rice ...
Speeding up the cyclic edit distance using LAESA with early abandon
The cyclic edit distance between two strings is the minimum edit distance between one of this strings and every possible cyclic shift of the other. This can be useful, for example, in image analysis where strings describe ...
Roadmap on optical security: Optical encryption by computational ghost imaging
(IOP Publishing, 2016)
Information security and authentication are important challenges facing society. Recent attacks by hackers on the databases of large commercial and financial companies have demonstrated that more research and development ...
On the Dynamic Time Warping of Cyclic Sequences for Shape Retrieval
In the last years, in shape retrieval, methods based on Dynamic Time Warping and sequences where each point of the contour is represented by elements of several dimensions have had a significant presence. In this approach ...
The Euler Number from the Distance Function
(International Society for Stereology, 2013)
We present a new method to obtain the Euler number of a domain based on the tangent counts of concentric spheres in R3 (or circles in R2), with respect to the center O, that sweeps the domain. This method is derived from ...
The Chern–Osserman inequality for minimal surfaces in a Cartan–Hadamard manifold with strictly negative sectional curvatures
(Springer Netherlands, 2014)
We state and prove a Chern–Osserman-type inequality in terms of the volume growth for minimal surfaces S which have finite total extrinsic curvature and are properly immersed in a Cartan–Hadamard manifold N with sectional ...
Geospatial information infrastructures to address spatial needs in health: Collaboration, challenges and opportunities
Most health-related issues such as public health outbreaks and epidemiological threats are better understood from a spatial–temporal perspective and, clearly demand related geospatial datasets and services so that decision ...
