Laser-induced formation of bismuth nanoparticles
(Royal Society of Chemistry, 2018)
In the current communication, the synthesis of metallic Bi nanoparticles
with coexisting crystallographic structures (rhombohedral,
monoclinic, and cubic) obtained via direct femtosecond laser irradiation
of NaBiO3 is ...
On wavelet-based energy densities for spatial point processes
(Springer, 2013-08)
A spatial point process can be considered a random measure and therefore represented as a countable sum of Delta Dirac measures concentrated at some points of the process. Applying a two-dimensional continuous wavelet ...
Identifying crime generators and spatially overlapping high-risk areas through a nonlinear model: A comparison between three cities of the Valencian region (Spain)
(Wiley, 2021-06-29)
The behavior and spatial distribution of crime events can be explained through the characterization of an area in terms of its demography, socioeconomy, and built environment. In particular, recent studies on the incidence ...
Bag-of-words with aggregated temporal pair-wise word co-occurrence for human action recognition
(Elsevier, 2014)
The bag-of-words (BoW) representation has successfully been used for human action recognition from
videos. However, one limitation of the standard BoW is that it ignores spatial and temporal relationships
between the ...
Exploring some practical issues of SVM+: Is really privileged information that helps?
(Elsevier, 2014)
Learning using privileged information (LUPI) is a machine learning paradigm which aims at improving classification by taking advantage of information that is only available at training time —not at test time. SVM+ is an ...
Risk factors and spatial distribution of urban rat infestations
(Springer Verlag, 2014-03)
Urban rat infestations have multifactorial causes and may result in severe public health and environmental problems, as well as heavy economic losses. The identification of putative environmental determinants of urban rat ...
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 ...
Human gesture recognition using three-dimensional integral imaging
(Optical Society of America, 2014)
Three-dimensional (3D) integral imaging allows one to reconstruct a 3D scene, including range information, and provides sectional refocused imaging of 3D objects at different ranges. This paper explores the potential use ...
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 new extrinsic sample mean in the shape space with applications to the boundaries of anatomical structures
(Wiley, 2016-02-16)
Shape analysis is of great importance in many fields of medical imaging and computational biology. In this paper, we consider the shape space as the set of smooth planar immersed curves in inline image (parameterized curves) ...
