Controlar escoamento urbano através de Sistemas de Drenagem Urbano Sustentável (SUDS): Poços / Trincheiras de infi ltração
No full textEn el marco del manejo eficiente del recurso hídrico y el medio ambiente, el control de las escorrentías superficiales es un área de estudio de gran importancia en el desarrollo de las ciudades, pues su crecimiento exponencial y el aumento de zonas duras no permeables hace que el transporte de la escorrentía tome tiempos mayores. Consecuentemente, se generan implicaciones ambientales y económicas importantes que conllevan a la implementación de estructuras que den mayor holgura para el respectivo transporte. Cuando no es posible el control mediante estos elementos, se presentan fenómenos de inundación que afectan la calidad de vida de la población y se deben generar planes de emergencia para mitigar estos riesgos. La implementación de sistemas de drenaje sostenible alternativos como los Sistemas de Drenaje Urbano Sostenibles (SUDS), permite aminorar y retrasar los picos de tormenta que se presentan en las ciudades. A continuación, se presenta un análisis de resultados correspondiente a la respuesta analítica mediante la modelación hidráulica e hidrológica y la aplicación de EPA-SWMM, programa desarrollado por la U.S. Environmental Protection Agency (EPA) para el análisis de lluvia y comportamiento hidráulico de redes de alcantarillado.In the framework of the efficient management of water resources and the environment, the control of the surface runoff is an area of study of great importance in the development of cities, because their exponential growth and the increase of non-permeable hard zones produces greater runoff transport times. Thus, environmental and economic implications are generated that leads to the implementation of mayor structures for the respective transport. When the control by these elements is not possible, flood phenomena affect the quality of life of the population and emergency plans for these risks must be generated. The implementation of alternative sustainable drainage systems such as Sustainable Urban Drainage Systems (SUDS) allows to reduce and to delay the storm surges that occur in. Next, an analysis of results related to hydraulic and hydrological modeling and the EPA-SWMM, a program developed by the United States Environmental Protection Agency (EPA) for the analysis of rainfall and hydraulic behavior of networks of Sewerage.Recibido: julio 19 de 2017 - Aceptado: junio 28 de 2018E.

Sobre a recepción e fortuna crítica do chamado “Conto gallego” de Rosalía de Castro
No full text[Resumo]:
O denominado “Conto Gallego”, único exemplo de prosa
narrativa galega de Rosalía de Castro, foi considerado durante
anos un texto de dubidosa autoría, en parte polos problemas
ligados á súa problemática difusión, o que provocou un certo
silencio bibliográfi co e que fose un texto escasamente estudado.
No artigo ofrécese unha completa revisión das valoracións
e lecturas que sobre el se teñen feito, como exemplo da
reavaliación crítica a que foi submetida a obra rosaliana nos
últimos trinta anos.[Abstract]: For years, scholars have argued over the authorship of Rosalía de Castro’s only narrative prose text in Galician, her so-called Conto Gallego (‘A Galician Tale’). The confusion with regard to the identity of its author, due in part to problems in relation to how the text was originally transmitted, has led to its frequent omission from de Castro’s bibliography and a tendency to be overlooked by scholars of her work. This article proposes a complete reassessment and revision of the tale, as part of the critical reappraisal of de Castro’s writing over the past thirty years

Methodology for Determining the Maximum Potentially Recoverable Energy in Water Distribution Networks
No full text[EN] The excess pressure available in water distribution networks (WDNs) is a relevant aspect in the management and appropriate handling of water resources. If a WDN meets the minimum performance criteria (minimum pressure and maximum flow), excess pressure can occur throughout the day, which is usually lost. These excesses could be considered as potentially recoverable energy (PRE). One way of taking advantage of this energy is to find the nodes on the network where this excess pressure is evident and try to analyze the possible amount of PRE. This work presents a methodology to determine the maximum PRE in a WDN. This methodology includes the locations of the points where the installation of recovery devices leads to this maximum PRE. The method is based on reducing pressures but maintaining circulating points through the lines. Additionally, a new energy balance that allows visualizing and breaking down in more detail all the energy found
in a WDN is proposed. The analysis is carried out in an extended period considering different feeding points either by gravity or pumping. Finally, a network resilience index called the Potentially
Recoverable Energy Index (PREI) in WDNs is proposed, with which it is possible to diagnose and determine how much energy could be recovered from the network. Study cases presented demonstrate the effectiveness of the methodology and will allow the development of optimizations in the operation of WDNs in favor of the good management of water and energy resources.This research was funded by the Program Fondecyt Regular, grant number 1180660.Cubides-Castro, ED.; López-Aburto, CS.; Iglesias Rey, PL.; Martínez-Solano, FJ.; Mora-Meliá, D.; Iglesias-Castelló, M.

Rosalía de Castro e as escritoras angloamericanas do seu tempo en La hija del mar
No full text[Resumo] O presente traballo analiza a recepción por parte de Rosalía de Castro
de escritoras europeas e americanas dos séculos XVIII e XIX coas que
compartiu preocupacións de autoría, de xénero, temáticas e literarias.
Prestarase especial atención ás referencias intertextuais de escritoras mencionadas pola propia Rosalía nos seus escritos, en particular
á inglesa Charlotte Turner Smith e á norteamericana Maria Susanna
Cummins e á identificación de Rosalía con elas e coas súas carreiras
literarias. A análise permite afirmar que nas súas obras propuxeron
cuestións relativas ás mulleres, á súa orfandade e ás súas capacidades,
ben como ao feito de que as habelencias femininas son truncadas pola
sociedade circundante, en particular, se teñen vocación de as desenvolveren en igualdade cos varóns.[Abstract] This article deals with the reception by Rosalía de Castro of eighteenth- and nineteenth-century European and American female
writers with whom she shared preocupations about authorship and
gender, as well as thematic and literary concerns. Special attention
will be paid to the intertextual references of the writers mentioned
by the Galician author, particularly Charlotte Turner Smith and
Maria Susanna Cummins, and to de Castro’s identification with
these writers and their literary careers. This analysis will show that
they presented issues pertaining to female foundlings, their capacities and how their abilities were not accepted in their respected
societies, particularly if they wanted to behave as males would do.Ministerio de Comercio, Economía y Empresa; FEM2015-66937-PXunta de Galicia; ED431D 2017/1

Inferencia de deterioro cognitivo en pacientes con enfermedad de Parkinson a partir de evaluaciones espaciotemporales de la marcha mediante aprendizaje automático
No full textilustraciones, diagramasCognitive decline is a significant complication in Parkinson’s disease (PD), severely
impacting patients’ quality of life. Early identification of these deficits is crucial
to improving clinical intervention and disease prognosis. This study investigates
the relationship between spatiotemporal gait characteristics and cognitive decline
in early-stage PD patients. Data from 48 patients were obtained from the Parkinson’s Progression Markers Initiative (PPMI) database, categorised into two groups:
patients without cognitive impairment (PD) and those exhibiting some degree of
cognitive decline (PD-CD). Seven machine learning algorithms were implemented,
optimising hyperparameters and addressing class imbalance. Model performance
was evaluated using Recall, Precision, F1-score, and Accuracy, prioritising sensitivity to assess the classifiers’ ability to detect the minority class.
The results indicate that spatiotemporal gait characteristics significantly differentiate PD and PD-CD groups. Among the evaluated models, the Multilayer Perceptron
(MLP) and the Cognitive Assessment through Gait in Parkinson’s Disease (CoGait-PD) demonstrated the highest performance, achieving accuracy scores of 0.78 ± 0.08
and 0.77 ± 0.05, respectively. Both models balanced sensitivity and precision, excelling in identifying positive cases and reducing false negatives.
These findings suggest that gait characteristics may serve as non-invasive biomarkers for early detection of cognitive decline in PD patients. Additionally, machine
learning models, particularly CoGait-PD and MLP, show strong potential for clinical assessment. Further studies are recommended to validate these findings and
explore their applicability in clinical settings.El deterioro cognitivo es una de las complicaciones más relevantes en la enfermedad de Parkinson (PD), afectando significativamente la calidad de vida de los pacientes. La identificación temprana de estos déficits es crucial para mejorar la intervención clínica y el pronóstico de la enfermedad. Este estudio analiza la relación entre las características espaciotemporales de la marcha y el deterioro cognitivo en pacientes con PD en etapa temprana. Se utilizaron datos de 48 pacientes de la base de datos de la Parkinson’s Progression Markers Initiative (PPMI), dividiendo la muestra en dos grupos: pacientes sin deterioro cognitivo (PD) y aquellos con algún grado de deterioro cognitivo (PD-DC). Para el análisis, se implementaron siete algoritmos de aprendizaje automático, optimizando sus hiperparámetros y abordando el desequilibrio de clases. El desempeño de los modelos se evaluó mediante métricas como Recall, Precisión, F1-score y Exactitud (Accuracy), priorizando la sensibilidad para evaluar la capacidad de detección de la clase minoritaria. Los resultados indicaron que las características espaciotemporales de la marcha permiten diferenciar significativamente entre los grupos PD y PD-DC. Entre los modelos evaluados, el Perceptrón Multicapa (MLP) y el Cognitive Assessment through Gait in Parkinson’s Disease (CoGait-PD) presentaron el mejor desempeño, alcanzando valores de exactitud de 0.78 ± 0.08 y 0.77 ± 0.05, respectivamente. Estos modelos lograron un equilibrio entre sensibilidad y precisión, destacándose en la identificación de casos positivos y reduciendo falsos negativos. Los hallazgos sugieren que las características de la marcha pueden servir como biomarcadores no invasivos para la detección temprana del deterioro cognitivo en pacientes con PD. Además, los modelos de aprendizaje automático, particularmente CoGait-PD y MLP, muestran un alto potencial en la evaluación clínica. Se recomienda realizar estudios adicionales para validar estos hallazgos y explorar su aplicabilidad en entornos clínicos (Texto tomado de la fuente)MaestríaMagíster en Ingeniería BiomédicaMotion and Biosignal Analysi
