Bayesian spatio-temporal prediction of cancer dynamics
(Elsevier, 2015-09)
In this paper we analyze the spatio-temporal dynamics of brain tumors. These objects are originally processed from computer tomography images, and can be depicted as a collection of image pixels with varying degrees of ...
Security authentication using phase-encoded nanoparticle structures and polarized light
(Optical Society of America, 2015)
Phase-encoded nanostructures such as quick response (QR) codes made of metallic nanoparticles are suggested to be used in security and authentication applications. We present a polarimetric optical method able to authenticate ...
Controlled multi-beam supercontinuum generation in fused silica by means of spatial light modulators
(IEEE, 2015-06)
We report on deterministic femtosecond multi-filamentation in fused silica by encoding a diffractive microlens array into a spatial light modulator. The efficiency and focal length of each microlens are electronically ...
Optimal Multicasting in Millimeter Wave 5G NR with Multi-beam Directional Antennas
(Institute of Electrical and Electronics Engineers, 2021-12)
The support of multicast communications in the fifth-generation (5G) New Radio (NR) system poses unique
challenges to system designers. Particularly, the highly directional antennas do not allow to serve all the user ...
Assessing similarities between spatial point patterns with a Siamese neural network discriminant model
(Springer, 2023)
Identifying structural differences among observed point patterns from several populations is of interest in several applications. We use deep convolutional neural networks and employ a Siamese framework to build a discriminant ...
Environmental service discovery based on semantically annotated OGC service descriptions
(ACM, 2013-03)
Environmental information is a valuable resource for a wide range
of applications and decision support systems in different domains.
This is reflected in different initiatives around the world, such as
the Open Geospatial ...
ATM-based analysis and recognition of handball team activities
(Elsevier, 2015)
In this paper, a new methodology based on the Author Topic Model (ATM) method is presented to perform team activity recognition and analysis in handball videos. Instead of using players׳ trajectories we just rely on low ...
Mobile Access to Sensor Network: A Use Case on Wildfire Monitoring
(Springer International Publishing, 2014)
These networks provide large volumes of data in many different formats, resolution and scales. The data are of different types and character: from meteorological conditions to air quality and the concentrations of pollutants ...
Kriging with external drift for functional data for air quality monitoring
(Springer Verlag, 2014-07)
Functional data featured by a spatial dependence structure occur in many environmental sciences when curves are observed, for example, along time or along depth. Recently, some methods allowing for the prediction of a curve ...
A note on smoothness measures for space-time surfaces
(Springer Verlag, 2013-09)
The differentiability of a random field has a direct relationship with the differentiability of its covariance function. We review the concept of differentiability of space–time covariance models and random fields, and its ...
