Directional analysis for point patterns on linear networks
(Wiley, 2021)
info:eu-repo/semantics/article,
Statistical analysis of point processes often assumes that the underlying process is isotropic in the sense that its distribution is invariant under rotation. For point processes on R-2, some tests based on the K-function ...
Nonlinear stability of elliptic equilibria in Hamiltonian systems with exponential time estimates
(American Institute of Mathematical Sciences (AIMS), 2021)
Artículo / Artikulua,
In the framework of nonlinear stability of elliptic equilibria in Hamiltonian systems with n degrees of freedom we provide a criterion to obtain a type of formal stability, called Lie stability. Our result generalises ...
A mathematical approach to law and deal modelling: legislation and agreements
(MDPI, 2021)
info:eu-repo/semantics/article,
Social norms are a set of rules to be followed by the people of a community in order to have a better coexistence, to which the behaviors, tasks, and activities of the human being must be adjusted. The set or system of ...
Greedy approximation for biorthogonal systems in quasi-Banach spaces
(Instytut Matematyczny, 2021)
info:eu-repo/semantics/article,
The general problem addressed in this work is the development of a systematic study of the thresholding greedy algorithm for general biorthogonal systems in quasi-Banach spaces from a functional-analytic point of view. If ...
Towards interval uncertainty propagation control in bivariate aggregation processes and the introduction of width-limited interval-valued overlap functions
(Elsevier, 2021)
info:eu-repo/semantics/article,
Overlap functions are a class of aggregation functions that measure the overlapping degree between two values. They have been successfully applied as a fuzzy conjunction operation in several problems in which associativity ...
Selecting freight transportation modes in last-mile urban distribution in Pamplona (Spain): an option for drone delivery in smart cities
(MDPI, 2021)
info:eu-repo/semantics/article,
Urban distribution in medium-sized cities faces a major challenge, mainly when deliveries are difficult in the city center due to: an increase of e-commerce, weak public transportation system, and the promotion of urban ...
Phenolic composition of grape stems from different Spanish varieties and vintages
(MDPI, 2021)
info:eu-repo/semantics/article,
Grape stems are a by‐product from the wine industry that has been underused to date despite having great potential for the agro‐food and cosmetic industries. The aim of the present work was to characterize grape stem ...
What kind of school organizational decisions serve to enhance sustainable personal and social growth?
(MDPI, 2021)
info:eu-repo/semantics/article,
Sustainable decisions in education are those which pursue long-term achievements for students. In many cases, the principals of the schools are those who must make these decisions. In this paper we explore some of the ...
The sustainability dimensions in intelligent urban transportation: a paradigm for smart cities
(MDPI, 2021)
info:eu-repo/semantics/article,
The transportation sector has traditionally been considered essential for commercial activities, although nowadays, it presents clear negative impacts on the environment and can reduce social welfare. Thus, advanced ...
