Unifying Chance-Constrained and Robust Optimal Power Flow for Resilient Network Operations.
Uncertainty in renewable energy generation has the potential to adversely impact the operation of electric networks. Numerous approaches to manage this impact have been proposed, ranging from stochastic and chance-constrained ... -
Upper endpoint estimates and extrapolation for commutators.
(Instituto de Matemática de Bahía Blanca (CONICET - UNS), 2023)In this note we revisit the upper endpoint estimates for commutators following the line by Harboure, Segovia, and Torrea [Illinois J. Math. 41 no. 4 (1997), 676–700]. Relying upon the suitable BMO subspace suited for the ... -
Use of Neural Networks for Tsunami Maximum Height and Arrival Time Predictions
Rodríguez Gálvez, Juan Francisco; Macías-Sánchez, Jorge
; Castro-Díaz, Manuel Jesús; De-la-Asunción-Hernández, Marc (IOAP-MPDI, 2022-06-13)
Operational TEWS play a key role in reducing tsunami impact on populated coastal areas around the world in the event of an earthquake-generated tsunami. Traditionally, these systems in the NEAM region have relied on the ... -
Using Peer Review for Student Performance Enhancement: Experiences in a Multidisciplinary Higher Education Setting.
Serrano-Aguilera, Juan José; Tocino-Sánchez, Alicia; Fortes-Rodríguez, Sergio; Martín-Fernández, Cristian; Mercade-Mele, Pere; Moreno-Sáez, Rafael Jesús; Muñoz-Gallego, Antonio Jesús; Palomo-Hierro, Sara; Torres-Signes, Antoni[et al.] (MDPI, 2021-02)
Nowadays one of the main focuses of the Spanish University system is achieving the active learning paradigm in the context of its integration into the European Higher Education Area. This goal is being addressed by means ... -
Warm-starting constraint generation for mixed-integer optimization: A Machine Learning approach
Jiménez-Cordero, María Asunción; Morales-González, Juan Miguel; Pineda-Morente, Salvador (Elsevier, 2022-10-11)
Mixed Integer Linear Programs (MILP) are well known to be NP-hard (Non-deterministic Polynomial-time hard) problems in general. Even though pure optimization-based methods, such as constraint generation, are guaranteed to ... -
