First order differential systems with a nonlinear boundary condition via the method of solution-regions
(Springer Nature, 2021)In this article we extend the known theory of solution regions to encompass nonlinear boundary conditions. We both provide results for new boundary conditions and recover some known results for the linear case -
First-Order Singular and Discontinuous Differential Equations
(SpringerOpen, 2009)We use subfunctions and superfunctions to derive sufficient conditions for the existence of extremal solutions to initial value problems for ordinary differential equations with discontinuous and singular nonlinearities. -
FORTLS: An R Package for Processing TLS Data and Estimating Stand Variables in Forest Inventories
(MDPI, 2021)Terrestrial Laser Scanning (TLS) enables rapid, automatic, and detailed 3D representation of surfaces with an easily handled scanner device. TLS, therefore, shows great potential for use in Forest Inventories (FIs). However, ... -
Fractional Langevin Equation Involving Two Fractional Orders: Existence and Uniqueness Revisited
(MDPI, 2020)We consider the nonlinear fractional Langevin equation involving two fractional orders with initial conditions. Using some basic properties of Prabhakar integral operator, we find an equivalent Volterra integral equation ... -
Functional covariate-adjusted partial area under the specificity-ROC curve with an application to metabolic syndrome diagnosis
(The Institute of Mathematical Statistics, 2016)Due to recent advances in technology, medical diagnosis data are becoming increasingly complex and, nowadays, applications where measurements are curves or images are ubiquitous. Motivated by the need of modeling a functional ... -
Functional Location-Scale Model to Forecast Bivariate Pollution Episodes
(MDPI, 2020)Predicting anomalous emission of pollutants into the atmosphere well in advance is crucial for industries emitting such elements, since it allows them to take corrective measures aimed to avoid such emissions and their ... -
A Fuzzy Method for Solving Fuzzy Fractional Differential Equations Based on the Generalized Fuzzy Taylor Expansion
(MDPI, 2020)In this field of research, in order to solve fuzzy fractional differential equations, they are normally transformed to their corresponding crisp problems. This transformation is called the embedding method. The aim of this ... -
Gamestorming for the Conceptual Design of Products and Processes in the context of engineering education
(Elsevier, 2018)Creating an ideal environment to develop creativity and innovation in engineering education is a real challenge. One alternative approach can be based in the application of Gamestorming methodology that considers the use ... -
Generalized Hermite Distribution Modelling with the R Package hermite
(R Foundation for Statistical Computing, 2015)The Generalized Hermite distribution (and the Hermite distribution as a particular case) is often used for fitting count data in the presence of overdispersion or multimodality. Despite this, to our knowledge, no standard ... -
A Generalized Model to Estimate the Statistical Power in Mitochondrial Disease Studies Involving 2×k Tables
(Public Library of Science, 2013)Mitochondrial DNA (mtDNA) variation (i.e. haplogroups) has been analyzed in regards to a number of multifactorial diseases. The statistical power of a case-control study determines the a priori probability to reject the ... -
Generalizing the Convex Hull of a Sample: The R Package alphahull
(Foundation for Open Access Statistics, 2010-04-16)This paper presents the R package alphahull which implements the α-convex hull and the α-shape of a finite set of points in the plane. These geometric structures provide an informative overview of the shape and properties ... -
A Generative Angular Model of Protein Structure Evolution
(Oxford University Press, 2017-04-27)Recently described stochastic models of protein evolution have demonstrated that the inclusion of structural information in addition to amino acid sequences leads to a more reliable estimation of evolutionary parameters. ... -
Global attraction in a system of delay differential equations via compact and convex sets
(American Institute of Mathematical Sciences, 2020)We provide sufficient conditions for a concrete type of systems of delay differential equations (DDEs) to have a global attractor. The principal idea is based on a particular type of global attraction in difference equations ... -
Global attractivity of solutions for nonlinear fractional order Riemann-Liouville Volterra-Stieltjes partial integral equations
(University of Szeged , 2012)This paper deals with the existence and the attractivity of solutions of a class of fractional order functional Riemann-Liouville Volterra-Stieltjes partial integral equations. Our results are obtained by using the ... -
Glycemic Variability and Its Association With Demographics and Lifestyles in a General Adult Population
(SAGE Publications, 2017)Objective: The objective was to investigate glycemic variability indices in relation to demographic factors and common environmental lifestyles in a general adult population. Methods: The A Estrada Glycation and Inflammation ... -
Goodness-of-fit tests for the functional linear model based on randomly projected empirical processes
(Institute of Mathematical Statistics, 2019)We consider marked empirical processes indexed by a randomly projected functional covariate to construct goodness-of-fit tests for the functional linear model with scalar response. The test statistics are built from ... -
Gronwall–Bellman estimates for linear Volterra-type inequalities with delay
(University of Szeged, 2018-10-01)We obtain some estimates of Gronwall–Bellman-type for Volterra’s inequalities, which have applications to the study of the stability properties of the solutions to some linear functional differential equations. -
GsymPoint: An R Package to Estimate the Generalized Symmetry Point, an Optimal Cut-off Point for Binary Classification in Continuous Diagnostic Tests
