These failures are described by a model that considers possible outages or partial failures in every single actuator of each decentralised controller. The control design is performed through two steps. First, a decentralised reliable guaranteed cost control set is derived and, second, a feasible linear matrix inequalities procedure is presented for the effective construction of the control set. A numerical example illustrates the efficiency of the proposed control schemePeer ReviewedPostprint (published version

    In the last years, chiral smectic liquid crystals with V-shaped electro-optic response have been reported as one of the most promising technologies for display applications. In this work,some experiments have been made in order to check electrooptical performance of this kind of materials. Particularly, frequency dependence of optical response and memory effect in transmission have been analyzed. Microscopic observations of intermediate transmission levels and measurements of apparent tilt angle and response time have been also carried out

    Programa Oficial de Doutoramento en Estudos Literarios. 5020V01[Resumo] Estudo dos contactos interculturais entre Irlanda e Galicia a partir da análise do Leabhar Gabhála Éireann, libro redactado en gaélico a principios do s. XII en Leinster, que narra sagas de herois relacionadas coas seis conquistas da illa en tempos prehistóricos. Tras informar sobre os achádegos arqueolóxicos que permiten constatar que existiu unha cultura atlántica común á que estes pobos pertencían, faise un percorrido a través da historia e a literatura de Irlanda e Galicia para atopar as pegadas duns relatos que se converteron, durante as idades Moderna e Contemporánea, en mensaxe de resistencia identitaria céltica. Segue un estudo comparado entre estas culturas a través da toponimia e outros tipos de onomástica supervivente, así como cultos e ritos relixiosos, folclore e mitoloxía. O traballo remata cun estudo de caso de literatura comparada galego-irlandesa que, logo de presentar os nomes e a obra de Seamus Heaney e Luz Pozo Garza, comenta algúns textos de seu.[Resumen] Estudio de los contactos interculturales entre Irlanda y Galicia a partir del análisis del Leabhar Gabhála Éireann, libro redactado en gaélico a principios del s.

After a thorough research of archaeological findings which allows us to prove there was a common Atlantic culture that these peoples belonged to, a tour is made through the history and literature of Ireland and Galicia with the aim of finding traces of the narratives that later became a message of Celtic identity resistance during the Modern and Contemporary ages. A comparative study between these cultures is carried out through the use of toponymy and other types of surviving onomastics, including religious cults and rites, folklore, and mythology. The study concludes with a case study of Galician-Irish comparative literature by introducing the authors and works of Seamus Heaney and Luz Pozo Garza, as well as exploring some of their texts

    Clinical variant interpretation and biologically relevant reference transcripts.

    Get PDF
    Clinical variant interpretation is highly dependent on the choice of reference transcript. Although the longest transcript has traditionally been chosen as the reference, APPRIS principal and MANE Select transcripts, biologically supported reference sequences, are now available. In this study, we show that MANE Select and APPRIS principal transcripts are the best reference transcripts for clinical variation. APPRIS principal and MANE Select transcripts capture almost all ClinVar pathogenic variants, and they are particularly powerful over the 94% of coding genes in which they agree. We find that a vanishingly small number of ClinVar pathogenic variants affect alternative protein products. Alternative isoforms that are likely to be clinically relevant can be predicted using TRIFID scores, the highest scoring alternative transcripts are almost 700 times more likely to house pathogenic variants. We believe that APPRIS, MANE and TRIFID are essential tools for clinical variant interpretation.Research reported in this publication was supported by the National Human Genome Research Institute of the National Institutes of Health under Award Number U24HG007234.

    A combination of supervised dimensionality reduction and learning methods to forecast solar radiation

    Get PDF
    Machine learning is routinely used to forecast solar radiation from inputs, which are forecasts of meteorological variables provided by numerical weather prediction (NWP) models, on a spatially distributed grid. However, the number of features resulting from these grids is usually large, especially if several vertical levels are included. Principal Components Analysis (PCA) is one of the simplest and most widely-used methods to extract features and reduce dimensionality in renewable energy forecasting, although this method has some limitations. First, it performs a global linear analysis, and second it is an unsupervised method. Locality Preserving Projection (LPP) overcomes the locality problem, and recently the Linear Optimal Low-Rank (LOL) method has extended Linear Discriminant Analysis (LDA) to be applicable when the number of features is larger than the number of samples. Supervised Nonnegative Matrix Factorization (SNMF) also achieves this goal extending the Nonnegative Matrix Factorization (NMF) framework to integrate the logistic regression loss function. In this article we try to overcome all these issues together by proposing a Supervised Local Maximum Variance Preserving (SLMVP) method, a supervised non-linear method for feature extraction and dimensionality reduction. PCA, LPP, LOL, SNMF and SLMVP have been compared on Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) radiation data at two different Iberian locations: Seville and Lisbon. Results show that for both kinds of radiation (GHI and DNI) and the two locations, SLMVP produces smaller MAE errors than PCA, LPP, LOL, and SNMF, around 4.92% better for Seville and 3.12% for Lisbon. It has also been shown that, although SLMVP, PCA, and LPP benefit from using a non-linear regression method (Gradient Boosting in this work), this benefit is larger for PCA and LPP because SMLVP is able to perform non-linear transformations of inputs.This work has been made possible by projects funded by Agencia Estatal de Investigación (PID2019-107455RB-C22 / AEI / 10.13039/501100011033).

    SOWISP—A retrospective high spatial and temporal resolution database of the installed wind and solar PV power in Spain

    Get PDF
    The proposal of new energy systems based on renewable energies requires thorough research in order to derive technically reliable and economically sustainable systems. One of the key inputs of such research is constituted by reliable databases of renewable resources. Despite the great effort of the scientific community in recent years, most current databases are far from optimal. Although some databases are based on real data, they lack adequate spatial resolution and/or temporal coverage. Other databases are obtained by estimating renewable energy potential from meteorological reanalysis; however, these estimates are subject to high uncertainty. One of the main problems when building these renewable resource databases is the lack of actual values of installed capacity. In this study we present the SOlar and Wind Installed Spanish Power (SOWISP) database. SOWISP provides the actual installed capacity of wind and photovoltaic solar energy in each Spanish town, with a monthly resolution, and covering the period of 2015–2020. SOWISP has been developed and validated based on a careful and thorough compilation of different public databases. It covers the need for a publicly available database with sufficient spatial and temporal resolution suitable for the analysis of energy systems. Moreover, SOWISP, along with other freely available datasets, supports many modern applications. In addition, a Python package (available on GitHub) was developed for managing this databaseSpanish GovernmentJunta de Andalucia PID2019-107455RB-C21/AEI/92 10.13039/501100011033European CommissionUE-Junta de Andalucia PID2019-107455RB-C22/AEI/10.13039/501100011033 TEP-220 PAIDI2020-DOC_0111
