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 ...
A Comprehensive and Reproducible Comparison of Clustering and Optimization Rules in Wi-Fi Fingerprinting2020
(IEEE, 2020-08-17)
Wi-Fi fingerprinting is a well-known technique used for indoor positioning. It relies on a pattern recognition method that compares the captured operational fingerprint with a set of previously collected reference samples ...
Beyond Euclidean Distance for Error Measurement in Pedestrian Indoor Location
(Institute of Electrical and Electronics Engineers, 2020-09-04)
Indoor positioning systems (IPSs) suffer from a
lack of standard evaluation procedures enabling credible comparisons: this is one of the main challenges hindering their
widespread market adoption. Traditionally, accuracy ...
Functional marked point processes: a natural structure to unify spatio-temporal frameworks and to analyse dependent functional data
(Springer, 2020)
This paper treats functional marked point processes (FMPPs), which are defined asmarked point processes where the marks are random elements in some (Polish) func-tion space. Such marks may represent, for example, spatial ...
Training Engineers in the Use of Constraints to Create Quality 2D Pro les for 3D Models
(CAD Solutions, 2021)
Historically, different strategies utilized in engineering and technical graphics reflect growing concern about improvement in CAD instruction and the introduction of product quality data in curricular activities. Our ...
A New Geometric Metric in the Shape and Size Space of Curves in R n
(MDPI, 2020-10-01)
Shape analysis of curves in Rn is an active research topic in computer vision. While shape itself is important in many applications, there is also a need to study shape in conjunction with other features, such as scale and ...
Femtosecond filamentation in sapphire with diffractive lenses
(Optical Society of America, 2013)
In this paper, we demonstrate novel properties in the phenomenology of supercontinuum generation in sapphire with diffractive lenses and provide a complete spatial, spectral, and temporal characterization of the so-generated ...
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 ...
Generalized elastodynamic model for nanophotonics
(American Physical Society, 2020)
A self-consistent theory for the classical description of the interaction of light and matter at the nanoscale is
presented, which takes into account spatial dispersion. Up to now, the Maxwell equations in nanostructure ...
Procedural modelling of terrains with constraints
(Springer, 2020-08-18)
Terrain is an essential part of any outdoor environment and, consequently, many techniques
have appeared that deal with the problem of its automatic generation, such as procedural
modeling. One form to create terrains ...
