Solving the stochastic team orienteering problem: comparing simheuristics with the sample average approximation method
The team orienteering problem (TOP) is anNP-hardoptimization problem with an increasing number of po-tential applications in smart cities, humanitarian logistics, wildfire surveillance, etc. In the TOP, a fixed fleetof ... -
Solving vehicle routing problems under uncertainty and in dynamic scenarios: from simheuristics to agile optimization
Many real-life applications of the vehicle routing problem (VRP) occur in scenarios subject to uncertainty or dynamic conditions. Thus, for instance, traveling times or customers demands mightMany real-life applications ... -
Some bipolar-preferences-involved aggregation methods for a sequence of OWA weight vectors
The ordered weighted averaging (OWA) operator and its associated weight vectors have been both theoretically and practically verified to be powerful and effective in modeling the optimism/pessimism preference of decision ... -
Some construction methods for pseudo-overlaps and pseudo-groupings and their application in group decision making
In many real-world scenarios, the importance of different factors may vary, making commutativity an unreasonable assumption for aggregation functions, such as overlaps or groupings. To address this issue, researchers have ... -
Some preference involved aggregation models for basic uncertain information using uncertainty transformation
In decision making, very often the data collected are with different extents of uncertainty. The recently introduced concept, Basic Uncertain Information (BUI), serves as one ideal information representation to well model ... -
The Southwestern Europe Meteor Network: development of new artificial intelligence tools and remarkable fireballs observed from January to February 2022
In this work we focus on the development of an artificial intelligence in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. This is named AIMIE, and is capable of writing scientific ... -
The Southwestern Europe Meteor Network: new advances and analysis of bright fireballs recorded from September to December 2021
In this work we focus on some recent improvements performed in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. Thus, by employing artificial intelligence methods, we have significantly ... -
The Southwestern Europe Meteor Network: notable meteors spotted between December 2022 and January 2023
We present in this report the analysis of some of the notable meteors registered in the framework of the Southwestern Europe Meteor Network between December 2022 and January 2023. These were recorded from Spain. Their peak ... -
The Southwestern Europe Meteor Network: recent advances and analysis of bright fireballs recorded along April 2021
We present here some recent improvements performed in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. In particular, we focus on the development of the first digital database dedicated ... -
The Southwestern Europe Meteor Network: remarkable bolides recorded from March to May 2022
Some of the remarkable bolides spotted in the framework of the Southwestern Europe Meteor Network from March to May 2022 are described here. These have been observed from the Iberian Peninsula. Their absolute magnitude ... -
Space mission risk, sustainability and supply chain: review, multi-objective optimization model and practical approach
This paper investigates the convergence of risk, sustainability, and supply chain in space missions, including a review of fundamental concepts, the introduction of a multi-objective conceptual optimization model, and ... -
Space-time analysis of ovarian cancer mortality rates by age groups in Spanish provinces (1989-2015)
Background: Ovarian cancer is a silent and largely asymptomatic cancer, leading to late diagnosis and worse prognosis. The late-stage detection and low survival rates, makes the study of the space-time evolution of ovarian ... -
Space-time interactions in bayesian disease mapping with recent tools: making things easier for practitioners
Spatio-temporal disease mapping studies the distribution of mortality or incidence risks in space and its evolution in time, and it usually relies on fitting hierarchical Poisson mixed models. These models are complex for ... -
Spanish HTT gene study reveals haplotype and allelic diversity with possible implications for germline expansion dynamics in Huntington disease
We aimed to determine the genetic diversity and molecular characteristics of the Huntington disease (HD) gene (HTT) in Spain. We performed an extended haplotype and exon one deep sequencing analysis of the HTT gene in a ... -
Sparse approximation using new greedy-like bases in superreflexive spaces
This paper is devoted to theoretical aspects of optimality of sparse approximation. We undertake a quantitative study of new types of greedy-like bases that have recently arisen in the context of non-linear m-term approximation ... -
A splitting uniformly convergent method for one-dimensional parabolic singularly perturbed convection-diffusion systems
In this paper we deal with solving robustly and efficiently one-dimensional linear parabolic singularly perturbed systems of convection-diffusion type, where the diffusion parameters can be different at each equation and ... -
Stability of phenolic compounds in grape stem extracts
Grape stem is rich in phenolic compounds, especially stilbenes. These antioxidants can be degraded during the storage of grape stem extracts for long periods of time. The aim of this work was to analyze the stability of ... -
Steering the synthesis of Fe3O4 nanoparticles under sonication by using a fractional factorial design
Superparamagnetic iron oxide nanoparticles (MNPs) have the potential to act as heat sources in magnetic hyperthermia. The key parameter for this application is the specific absorption rate (SAR), which must be as large as ... -
Strengthened ordered directionally monotone functions. Links between the different notions of monotonicity
In this work, we propose a new notion of monotonicity: strengthened ordered directional monotonicity. This generalization of monotonicity is based on directional monotonicity and ordered directional monotonicity, two recent ... -
Strong negations and restricted equivalence functions revisited: an analytical and topological approach
Throughout this paper, our main idea is to analyze the concepts of a strong negation and a restricted equivalence function, that appear in a natural way when dealing with theory and applications of fuzzy sets and fuzzy ...
