Identification of patterns for space-time event networks
Springer (2022)This paper provides new tools for analyzing spatio-temporal event networks. We build time series of directed event networks for a set of spatial distances, and based on scan-statistics, the spatial distance that generates ... -
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 ... -
Improved constructions of nested code pairs
IEEE (2017-09)Two new constructions of linear code pairs C2 ⊂ C1 are given for which the codimension and the relative minimum distances M1(C1,C2), M1(C┴2 , C┴1) are good. By this we mean that for any two out of the three parameters the ... -
Improved evaluation codes defined by plane valuations
Elsevier (2010)We study improved evaluation codes associated with finitely generated order structures given by plane valuations. We show minimal sets of generators of the semigroups of these structures and provide parameters for the ... -
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 ... -
Improving the approximation of the probability density function of random nonautonomous logistic-type differential equations
John Wiley & Sons, Ltd. (2019-08-16)In this paper, we address the problem of approximating the probability density function of the following random logistic differential equation: P ′ (t, 𝜔�) = A(t, 𝜔�)(1 − P(t, 𝜔�))P(t, 𝜔�), t ∈ [t0, T], P(t0, 𝜔�) ... -
Incorporation of Circular Aspects into Product Design and Labelling: Consumer Preferences
MDPI (2018)The transition to a circular economy requires a fundamental change in products and the way they meet consumer demands. In this context, the aim of this article is to analyse the level of importance that consumers attach ... -
Indices of Maximal Invariant Subgroups and Solvability of Finite Groups
Springer Verlag (2019)Let A and G be finite groups and suppose that A acts coprimely on G via automorphisms. We study the solvability and supersolvability of G when certain proper maximal A-invariant subgroups of G have prime index or when ... -
Influencia de la encuesta de los estudiantes sobre la calidad docente en la universidad
UNED (2023-01-18)En el ámbito universitario español existen intereses particulares contrapuestos. Por un lado, uno de los principales objetivos de los estudiantes, si no el más importante, es aprobar las asignaturas. Estos consideran en ... -
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 ... -
Inhomogeneous K-function for germ–grain models
Elsevier (2016)In this paper, we propose the definition of the inhomogeneous K-function for germ–grain models, based on the reduced second order measure for general random sets. In general, grains in a germ–grain model can overlap, ... -
Inhomogeneous log-Gaussian Cox processes with piecewise constant covariates: a case study in modeling of COVID-19 transmission risk in East Java
Springer (2024)The inhomogeneous Log-Gaussian Cox Process (LGCP) defines a flexible point process model for the analysis of spatial point patterns featuring inhomogeneity/spatial trend and aggregation patterns. To fit an LGCP model to ... -
Integration of Environmental Models in Spatial Data Infrastructures: A Use Case in Wildfire Risk Prediction
Institute of Electrical and Electronics Engineers (IEEE) (2013)Achieving sustainable growth in our society implies monitoring our environment in order to measure human impact and detect relevant changes and detrimental driving factors such as wildfires and desertification. In order ... -
Integration rules from the equivalent differential equation method applied to equations of motion
Elsevier (2008)The numerical integration of equations of motion necessarily implies the presence of errors that depend on initial conditions as well as the different physical parameters under consideration. More particularly, dumping or ... -
Interpolating sequences for H∞(BH)
Taylor & Francis (2016)We prove that under the extended Carleson’s condition, a sequence (xn) ⊂ BH is linear interpolating for H∞(BH) for an infinite dimensional Hilbert space H. In particular, we construct the interpolating functions for each ... -
Interpolating sequences for weighted spaces of analytic functions on the unit ball of a Hilbert space
Springer Verlag (2018)We show that an interpolating sequence for the weighted Banach space of analytic functions on the unit ball of a Hilbert space is hyperbolically separated. In the case of the so-called standard weights, a su cient condition ... -
Interpolation sets and the size of quotients of function spaces on a locally compact group
American Mathematical Society (2016-03)We devise a fairly general method for estimating the size of quotients between algebras of functions on a locally compact group. This method is based on the concept of interpolation sets and unifies the approaches followed ... -
Interpolation sets in spaces of continuous metric-valued functions
Elsevier (2018-10)Let X and K be a Cech-complete topological group and a compact group, ˇ respectively. We prove that if G is a non-equicontinuous subset of CHom(X; K), the set of all continuous homomorphisms of X into K, then there is a ... -
Intersectoral and spatial spill-overs of firms’ bankruptcy in Spain
Springer (2022)This paper employs provincial data to study the spatial and intersectoral spill-overs in aggregate failure rates in Spain, by using an Integrated Nested Laplace Approximation. The analysis is based on NUTS3 data over the ... -
Intervention in prediction measure: a new approach to assessing variable importance for random forests
Springer Verlag (2017-05)Background Random forests are a popular method in many fields since they can be successfully applied to complex data, with a small sample size, complex interactions and correlations, mixed type predictors, etc. Furthermore, ...
