Unveiling the environment and faint features of the isolated galaxy CIG 96 with deep optical and HI observations
2018
Context. Asymmetries in atomic hydrogen (HI) in galaxies are often caused by the interaction with close companions, making isolated galaxies an ideal framework to study secular evolution. The AMIGA project has demonstrated that isolated galaxies show the lowest level of asymmetry in their HI integrated profiles compared to even field galaxies, yet some present significant asymmetries. CIG 96 (NGC 864) is a representative case reaching a 16% level. Aims. Our aim is to investigate the HI asymmetries of the spiral galaxy CIG 96 and what processes have triggered the star-forming regions observed in the XUV pseudo-ring. Methods. We performed deep optical observations at CAHA1.23m, CAHA2.2m and V…
Mainstream educational enrollment for students with SEN in the EU
2018
La educación inclusiva es un objetivo importante en la agenda de la UE. La reforma educativa iniciada en los años 70 ha impactado en la actual matriculación educativa en Europa. Al margen de la convergencia de la Unión, no todos los países tienen tasas de inclusión similares y eso implica una Europa a diferentes velocidades, no como un proyecto político sino como un hecho. Después de que la integración fuera reformulada como inclusión y a la vez que se continúan redactando declaraciones inter y supranacionales, nos hemos preguntado acerca de las tasas de matriculación educativa para una mejor comprensión de la educación inclusiva europea. Han sido analizadas las tasas de 28 países. 25 de el…
Competitive Discourses among the Valencian Right Wing: Communication and strategy in the 2019 regional elections
2020
The 2019 regional government election in The Valencian Country led to a new panorama on the Right. For the first time, there were three political parties competing for votes. In addition, the notoriety gained by the Far Right created a new political scene, posing a challenge to other parties. This paper analyses how the Partido Popular, Ciudadanos and Vox managed a campaign in which they were both electoral opponents but also potentially future parliamentary allies. The research examines the performance and campaign discourse of these three parties based on content analysis of the coverage of two newspapers’ (Levante-EMV and Las Provincias). The study examines the preferred frames of refere…

A Methodology to Derive Global Maps of Leaf Traits Using Remote Sensing and Climate Data
2018
This paper introduces a modular processing chain to derive global high-resolution maps of leaf traits. In particular, we present global maps at 500 m resolution of specific leaf area, leaf dry matter content, leaf nitrogen and phosphorus content per dry mass, and leaf nitrogen/phosphorus ratio. The processing chain exploits machine learning techniques along with optical remote sensing data (MODIS/Landsat) and climate data for gap filling and up-scaling of in-situ measured leaf traits. The chain first uses random forests regression with surrogates to fill gaps in the database (> 45% of missing entries) and maximizes the global representativeness of the trait dataset. Plant species are then a…
Slope units-based flow susceptibility model: using validation tests to select controlling factors
2011
A susceptibility map for an area, which is representative in terms of both geologic setting and slope instability phenomena of large sectors of the Sicilian Apennines, was produced using slope units and a multiparametric univariate model. The study area, extending for approximately 90 km2, was partitioned into 774 slope units, whose expected landslide occurrence was estimated by averaging seven susceptibility values, determined for the selected controlling factors: lithology, mean slope gradient, stream power index at the foot, mean topographic wetness index and profile curvature, slope unit length, and altitude range. Each of the recognized 490 landslides was represented by its centroid po…
Fish introductions and light modulate food web fluxes in tropical streams : a whole-ecosystem experimental approach
2016
Decades of ecological study have demonstrated the importance of top-down and bottom-up controls on food webs, yet few studies within this context have quantified the magnitude of energy and material fluxes at the whole-ecosystem scale. We examined top-down and bottom-up effects on food web fluxes using a field experiment that manipulated the presence of a consumer, the Trinidadian guppy Poecilia reticulata, and the production of basal resources by thinning the riparian forest canopy to increase incident light. To gauge the effects of these reach-scale manipulations on food web fluxes, we used a nitrogen (15N) stable isotope tracer to compare basal resource treatments (thinned canopy vs. con…
Sociālā tīmekļa datu apkopošana un analīze
2020
Twitter sociālā tīmekļa lietotāju daudzums visā pasaulē arvien palielinās, tāpēc pieaug arī lietotāju izveidoto datu daudzums un lietotāji nenojauš kādi dati īsti tiek dalīti ar citiem. Darba mērķis ir izpētīt sociālā tīmekļa Twitter tvītu metadatu sastāvu, tvītu ievākšanas metodes, publiski pieejamas sistēmas lietotāja profila analīzei un iegūt ieskatu kādu informāciju varētu uzskatīt par lietotājam nedrošu. Darba praktiskajā daļā izveidota tīmekļa vietne, kurā lietotājs var pieteikties sistēmā un pārbaudīt savus pieejamos datus par atrašanos vietu tvītu metadatos, ja atrašanās vietas opcija ir iespējota. Papildus darba praktiskajā daļā izveidota lietotne Twitter Baltijas valstu lietotāju …

CUDA-Accelerated Alignment of Subsequences in Streamed Time Series Data
2014
Euclidean Distance (ED) and Dynamic Time Warping (DTW) are cornerstones in the field of time series data mining. Many high-level algorithms like kNN-classification, clustering or anomaly detection make excessive use of these distance measures as subroutines. Furthermore, the vast growth of recorded data produced by automated monitoring systems or integrated sensors establishes the need for efficient implementations. In this paper, we introduce linear memory parallelization schemes for the alignment of a given query Q in a stream of time series data S for both ED and DTW using CUDA-enabled accelerators. The ED parallelization features a log-linear calculation scheme in contrast to the naive …
