An extremal problem with applications to renewable energy production
(EDP Sciences, 2021)
Dynamic optimisation provides complex challenges for optimal solution, but greatly increases applicability when considering time dependent situations. In this work, a constrained dynamic optimisation problem is analysed ...

Estimation of Particulate Matter Contributions from Desert Outbreaks in Mediterranean Countries (2015–2018) Using the Time Series Clustering Method
(MDPI, 2020-12-23)
North African dust intrusions can contribute to exceedances of the European PM10 and PM2.5 limit values and World Health Organisation standards, diminishing air quality, and increased mortality and morbidity at higher ...

Impact of soft-hydrothermal pre-treatments on the olive mill solid waste characteristics and its subsequent amaerobic digestion
(Springer, 2020-06-04)
The aim of this study was to investigate the effect of a soft-hydrothermal pre-treatment (SHP) on olive mill solid waste (OMSW) and its subsequent anaerobic digestion (AD). OMSW was pre-treated in an autoclave at temperatures ...

Analysis of an aggregate loss model in a Markov renewal regime
(ELSEVIER SCIENCE INC, 2020-12-22)
In this article we consider an aggregate loss model with dependent losses. The loss oc- currence process is governed by a two-state Markovian arrival process ( MAP 2 ), a Markov renewal process that allows for (1) correlated ...

Solutions of Optimization Problems on Hadamard Manifolds with Lipschitz Functions
(MDPI, 2020-05)
The aims of this paper are twofold. First, it is shown, for the first time, which types of nonsmooth functions are characterized by all vector critical points as being efficient or weakly efficient solutions of vector ...

On sparse optimal regression trees
(Elsevier, 2021-12-18)
In this paper, we model an optimal regression tree through a continuous optimization problem, where a compromise between prediction accuracy and both types of sparsity, namely local and global, is sought. Our approach can ...

Multiple Ordinal Correlation Based on Kendall’s Tau Measure : a Proposal
(MDPI, 2021)
The joint analysis of various ordinal variables is necessary in many experimental studies within research fields such as sociology and psychology. Therefore, the necessary measures of multiple ordinal dependence must be ...

On hub location problems in geographically flexible networks
(Wiley, 2021-04-30)
In this paper, we propose an extension of the uncapacitated hub location problem where the potential posi-tions of the hubs are not fixed in advance. Instead, they are allowed to belong to a region around an initialdiscrete ...

Estimation of supply and demand of tertiary education places in advanced digital profiles in the EU
(Publications Office, 2020)
In order to investigate the extent to which the education offer of advanced digital skills in Europe matches labour market needs, this study estimates the supply and demand of university places for studies covering the ...

New models and methods for classification and feature selection. a mathematical optimization perspective
(2021-07-27)
The objective of this PhD dissertation is the development of new models for Supervised Classification and Benchmarking, making use of Mathematical Optimization and Statistical tools. Particularly, we address the fusion ...
