A semiparametric spatiotemporal Hawkes-type point process model with periodic background for crime data
(WileyRoyal Statistical Society, 2018-12)
Past studies have shown that crime events are often clustered. This study proposes
a spatiotemporal Hawkes-type point process model, which includes a background component
with daily and weekly periodization, and a ...
Spatio‐temporal classification in point patterns under the presence of clutter.
(Wiley, 2019-08-23)
We consider the problem of detection of features in the presence of clutter forspatio-temporal point patterns. In previous studies, related to the spatial context,Kth nearest-neighbor distances to classify points between ...
Inhomogeneous higher-order summary statistics for point processes on linear networks
(Springer, 2020)
As a workaround for the lack of transitive transformations on linear network structures, which are required to consider different notions of distributional invariance, including stationarity, we introduce the notions of ...
Joint second-order parameter estimation for spatio-temporal log-Gaussian Cox processes
(Springer, 2018)
We propose a new fitting method to estimate the set of second-order parameters for the class of homogeneous spatio-temporal log-Gaussian Cox point processes. With simulations, we show that the proposed minimum contrast ...
Trivariate non‐Gaussian copulas to analyze the spatial behavior of rat sightings
(Wiley, 2018)
The brown rat lives with man in a wide variety of environmental contexts and adversely affects public health by transmission of diseases, bites, and allergies. Understanding behavioral and spatial correlation aspects of ...
A Distance-based Method for Spatial Prediction in the Presence of Trend
(SpringerInternational Biometric Society, 2020-06-01)
A new method based on distances for modeling continuous random data in Gaussian random fields is presented. In non-stationary cases in which a trend or drift is present, dealing with information in regionalized mixed ...
Ranking-based MCDM models in financial management applications: analysis and emerging challenges
(Springer, 2020)
Over the last decades, the academic and professional communities have paid much attention toward the use of multi-criteria
decision-making methods in a range of business and financial problems due to the variety and ...
Tailoring the Bactericidal Activity of Ag Nanoparticles/α-Ag2WO4 Composite Induced by Electron Beam and Femtosecond Laser Irradiation: Integration of Experiment and Computational Modeling
(American Chemical Society, 2019)
In nanotechnology research, significant effort is devoted to fabricating patterns of metallic nanoparticles on the surfaces of different semiconductors to find innovative materials with favorable characteristics, such as ...
Efficient Management of Multicast Traffic in Directional mmWave Networks
(Institute of Electrical and Electronics EngineersIEEE, 2021-03-11)
Multicasting is becoming more and more important in the Internet of Things (IoT) and wearable applications (e.g., high definition video streaming, virtual reality gaming, public safety, among others) that require high ...
Improving the Approximation of the First- and Second-Order Statistics of the Response Stochastic Process to the Random Legendre Differential Equation
(Springer Nature Switzerland AG, 2019-04-16)
In this paper, we deal with uncertainty quantification for the
random Legendre differential equation, with input coefficient A and initial conditions X0 and X1. In a previous study (Calbo et al. in Comput
Math Appl ...
