    [ES] La violencia ha sido considerada uno de los grandes ejes que explican el devenir de la humanidad desde los comienzos de la ciencia historiogrĂĄfica. Nos repele y nos atrae, deseamos olvidarla pero no debemos dejar que caiga en el olvido, aparenta estar ligada a momentos histĂłricos concretos pero atraviesa nuestro dĂ­a a dĂ­a
 QuizĂĄs por estas razones la violencia, en todas sus posibles manifestaciones, lejos de ser un tema obsoleto, continĂșa teniendo un gran potencial como cuestiĂłn historiogrĂĄfica, tal y como muestran las investigaciones que conforman este libro. De la mano de diferentes especialistas, y en un recorrido que va desde la Prehistoria hasta la Edad ContemporĂĄnea, este volumen colectivo analiza las violencias histĂłricas desde la antropologĂ­a fĂ­sica, la historia militar, la iconografĂ­a, o la historia de la infancia entre otros puntos de vista. Guerras, conflictos polĂ­ticos y religiosos y sus significados simbĂłlicos, o la violencia como espectĂĄculo son algunas de las cuestiones que abordan sus pĂĄginas. Si bien existen pocos temas que hayan sido mĂĄs estudiados por la historiografĂ­a que la violencia, este libro, fruto del Congreso Internacional La Violencia en la Historia, celebrado en la Universidad de Salamanca en octubre de 2019, es una muestra de que las preguntas histĂłricas nunca se agotan y de que las violencias pasadas deben seguir siendo revisitadas desde nuevos enfoques

    Classification of noise sources in LIGO gravitational wave observations using deep neural networks and model explainability analysis

    This document uses state of the art image classification techniques to automate the detection of noise sources in gravitational wave observations from the Laser Interferometer Gravitational-Wave Observatory (LIGO). Additionally, it analyzes the resulting model using post-hoc local interpretation methodologies with the intent of defining possible paths of improvement.Doble Doble Grado en IngenierĂ­a InformĂĄtica y AdministraciĂłn de Empresa

    This study seeks to instruct a group of learners on reading and vocabulary skills through different tasks. The purpose was to implement a course in order to explicitly instruct the students in the application of specific reading and vocabulary strategies to facilitate their reading practice in English. The research was carried out with a group of 26 eleventh grade students from Camilo Torres School in Santa Marta (Magdalena). Based on the context analysis and the problem definition, it was made the decision to carry out a qualitative action research based upon a Strategy Based Instruction (SBI) intervention to see its influence on the learnersĂŻ reading skills, to foster their motivation to read in English and to help them become more autonomous and efficient readers. The data collection was applied in different stages along the process, and according to the instruments which were applied during the inquiry. Preliminary instruments such as an interview, a questionnaire, and a class observation were applied and analyzed at the beginning of the research with the purpose of identifying the problem related to low performance in reading comprehension skills

    Horizontal Visibility graphs generated by type-I intermittency

    The type-I intermittency route to (or out of) chaos is investigated within the Horizontal Visibility graph theory. For that purpose, we address the trajectories generated by unimodal maps close to an inverse tangent bifurcation and construct, according to the Horizontal Visibility algorithm, their associated graphs. We show how the alternation of laminar episodes and chaotic bursts has a fingerprint in the resulting graph structure. Accordingly, we derive a phenomenological theory that predicts quantitative values of several network parameters. In particular, we predict that the characteristic power law scaling of the mean length of laminar trend sizes is fully inherited in the variance of the graph degree distribution, in good agreement with the numerics. We also report numerical evidence on how the characteristic power-law scaling of the Lyapunov exponent as a function of the distance to the tangent bifurcation is inherited in the graph by an analogous scaling of the block entropy over the degree distribution. Furthermore, we are able to recast the full set of HV graphs generated by intermittent dynamics into a renormalization group framework, where the fixed points of its graph-theoretical RG flow account for the different types of dynamics. We also establish that the nontrivial fixed point of this flow coincides with the tangency condition and that the corresponding invariant graph exhibit extremal entropic properties.Comment: 8 figure
