Monitoring of Power Over Fiber Signals Using Intercore Crosstalk in ARoF 5G NR Transmission
No full textPower over Fiber (PoF) needs safe and resilient operation of the infrastructure. In this article, we propose a new crosstalk-based remote monitoring technique of PoF signals in Spatial Division Multiplexing optical networks with no additional consumption at the remote radio head (RRH). We demonstrate this technique in a 250 m 7-core Multicore Fiber (MCF) transmitting three multiplexed 256 QAM 5G NR optical signals with a total throughput of 1.8 Gbps, a low-speed communications channel between a Central Office and a RRH, and a PoF signal delivering to feed the RRH's control board. The 5G NR optical signals are received at the RRH with EVM values within the limits stablished in the 3GPP 5G standard. The low-speed communications channel remotely manages the power supplied to a Radio Frequency Power Amplifier located at the RRH. The PoF signal is used to supply up to 131 mW to the control board of the RRH. The monitoring channel can accurately follow the optical power injected into the MCF or the optical power received at the RRH thanks to a real-time algorithm and an ad-hoc Matlab application, which also allows to control the PoF source and the low-speed communications channel
PYPSHORT: Minimum short-circuit current optimization model
No full textOptimization model to guarantee minimum levels of short-circuit current at specified nodes of a transmission system. The model includes the short-circuit current injected under fault conditions by inverter-based resources. To reach the specified short-circuit current, synchronous condensers are allocated across the network at a minimum cost. The model is written on Pyomo and can be solved using off-the-shelf MILP solvers such as CPLEX or Gurobi

A thermodynamic comparison between conventional, autothermal, and sorption-enhanced bio-oil steam reforming
No full textThis study presents a comprehensive thermodynamic analysis comparing three bio-oil steam reforming processes: traditional steam reforming, autothermal reforming, and sorption-enhanced steam reforming. Using Aspen Plus V12.1 software, simulations were performed to evaluate the hydrogen production, energy requirements, and the influence of key process variables such as temperature, pressure, or steam-to-carbon ratio. While traditional steam reforming is capable of achieving high hydrogen production, it requires substantial external energy input to drive forward the reaction given the endothermic nature of the reactions. In comparison, autothermal reforming allows thermal neutral conditions by integrating endothermic steam reforming with exothermic partial oxidation reactions. Although the energy requirements significantly decrease, it also leads to lower hydrogen yields due to its consumption in the oxidation processes. In contrast, sorption-enhanced steam reforming improves hydrogen production compared to the other configurations ascribed to the in-situ CO2 capture by using sorbents that shift the equilibrium towards hydrogen with purities over 98%, thus minimizing the need for additional gas separation processes apart from reducing the CO and CH4 formation. Additionally, the exothermic nature of CO2 capture reactions contributes to reducing the energy requirements or even generates excess energy at certain conditions that can be used as a heat source. The bio-oil composition, showed minor variations in hydrogen yields, making these findings applicable to different bio-oil compositions
Bestiario sacrificial de la inscripción de Marmarini
No full textExamen del vocabulario relacionado con el bestiario sacrificial de la inscripción griega de Marmarini. Esta inscripción de Marmarini fue escrita en una gran estela de piedra que data de mediados del siglo II a. C. Se desconoce su ubicación original (un santuario), ya que la estela fue saqueada y abandonada al borde de una carretera en la zona de Marmarini, al noreste de Larisa, en Tesalia, Grecia. La inscripción detalla los ritos y las normas de comportamiento en el santuario en el que se erigió la estela. La estela de piedra fue encontrada en 2002.La base de datos tiene como objetivo examinar todas las características del vocabulario sacrificial de esta inscripción, tanto en lo que respecta a los sacrificios animales como a los ritos asociados a ellos.Examen del texto griego de la inscripción y análisis comparativ
Entre lenguas: voces que leen a Gloria Anzaldúa 2025
No full textLectura de textos de Gloria Evangelina Anzaldúa (GEA) por parte de hablantes con acentos distintos del castellano, también en euskera, catalán, gallego, spanglish, rumano y armenio. Los audios establecieron un diálogo con imágenes producidas por la autora que fueron expuesto
as en el claustro del Colegio de Málaga del 30 de abril al 10 de junio de 2025. Por razones de derechos, las imágenes no pueden ser reproducidas pero los audios, en conjunto, son un homenaje a Gloria Anzaldúa en el vigésimo aniversario de su fallecimiento.

Guía de anotación de terminología financiera (FINTERM)
No full textThe creation of this document of annotation guidelines is framed in the Spanish national project CLARA-FINT. It consists of annotation guidelines that establish some indications and rules to create a dataset. The dataset is made up of financial texts from the annual reports of the main Spanish listed companies. Usually, said reports are publicly available under their respective shareholders website sections. The creation of a manually annotated gold standard by linguists using these guidelines is explored.
Annotation guidelines. It is a PDF file containing a description of the task with some theory, along with a number of rules, cases, exceptions, etc. This was made for serving as a reference while annotating financial terms. The criteria were established based on the task.</p
Perceived anxiety in family caregivers of individuals with Autism Spectrum Disorder, Down Syndrome and Williams Syndrome during the lockdown of the first COVID-19 wave in Spain. Data set.
No full textThis is a subsection of the Spanish data collected for an international Project (https://doi.org/10.17605/OSF.IO/5NKQ9) focused on studying the impact and response to the COVID-19 lockdown across the world for families of individuals with special needs.
In this particular Spanish subproject we studied the emotional impact of the strict lockdown during COVID-19 on Spanish caregivers of individuals with Autism Spectrum Disorder, Williams Syndrome and Down syndrome. Data were collected through an online survey. All caregivers reported concerns directly related to the pandemic and lockdown situation. Anxiety was predicted by previous anxiety disorder and the child’s diagnosis. The confinement in Spain was especially demanding for families of individuals with ASD
