Poesía en internet - Blogs y redes sociales.

Todavía se habla de “nuevas tecnologías” e Internet como algo novedoso e innovador en cuanto a su uso académico y literario, y, aunque en parte por su continuo cambio y actualización no deja de ser una acepción correcta, hay que dar por hecho que ya estamos dentro de un sistema tecnológico asentado, establecido, normalizado. Tanto es así, que esas “nuevas tecnologías” ya casi puede decirse que son “viejas”. En continuo cambio y evolución, sí, pero a una velocidad tal, que pasa casi desapercibido para el público general.Departamento de Literatura Española y Teoría de la Literatura y Literatura ComparadaGrado en Español: Lengua y Literatur

A machine learning approach with verification of predictions and assisted supervision for a rule-based network intrusion detection system

Network security is a branch of network management in which network intrusion detection systems provide attack detection features by monitorization of traffic data. Rule-based misuse detection systems use a set of rules or signatures to detect attacks that exploit a particular vulnerability. These rules have to be handcoded by experts to properly identify vulnerabilities, which results in misuse detection systems having limited extensibility. This paper proposes a machine learning layer on top of a rule-based misuse detection system that provides automatic generation of detection rules, prediction verification and assisted classification of new data. Our system offers an overall good performance, while adding an heuristic and adaptive approach to existing rule-based misuse detection systems

Analysis of tourism competitiveness and the key influencers

The aim of this research is measure and analyse the tourism competitiveness, which has become one of the great challenges of tourism researchers in recent years. We analyze the relationship between tourism competitiveness and major tourist magnitudes, relations with most tourist destinations, and some pillars that measure competitiveness such as sustainability. A methodology for calculating an indicator of tourism competitiveness based on a double reference point is proposed, taking into account a level of aspiration and reserve level for each pillar of competitiveness. They are considered different degrees of offset between the pillars so that a series of synthetic indices are calculated. Later the rankings obtained for each country are analyzed and conducted a series of analyses. This tool provides managers with a useful and accurate tool, an interactive flexible and easy to use multi-criteria decision on their part. Allows simulation of situations, monitoring and control of various indicators. Later statistical tools for analyzing and comparing tourism competitiveness and other quantities are used.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

A new survey of cool supergiants in the Magellanic Clouds

In this study, we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end of the brightness distribution of these stars, building a more representative dataset with which to extrapolate their behaviour to other Galactic and extra-galactic environments. We select candidates using only near infrared photometry, and with medium resolution multi-object spectroscopy, we perform spectral classification and derive their line-of-sight velocities, confirming the nature of the candidates and their membership to the clouds. Around two hundred new RSGs have been detected, hinting at a yet to be observed large population. Using near and mid infrared photometry we study the brightness distribution of these stars, the onset of mass-loss and the effect of dust in their atmospheres. Based on this sample, new a priori classification criteria are investigated, combining mid and near infrared photometry to improve the observational efficiency of similar programs as this.Comment: 39 pages, 10 figures.

It's online, it's news: appropriation of viral narratives by the digital press

At the crossway between information and entertainment, memes and newsgames are some of the news formats which, made viral in social networks, complement the informational experience and compete with the traditional news media in constructing alternative readings of the real. If in the light of Bakhtin (2002), journalism can be understood as a secondary discursive genre that feeds on primary genres (pp. 61-62), how is one to understand the circulation of these discourses produced from journalistic events in social networks? On the other hand, how are these narratives appropriated by the media? What functions do they play in media discourse? In this article we present some examples of products created from events of political impact. Thereafter, we discuss, by the analysis of a set of news stories, how the digital press, in the Iberian context, makes use of them. The purpose of this article is to contribute to the reflection on how the news media relate to these new narratives.info:eu-repo/semantics/publishedVersio

Uniqueness of limit cycles for quadratic vector fields

Producción CientíficaThis article deals with the study of the number of limit cycles surrounding a critical point of a quadratic planar vector field, which, in normal form, can be written as x ′ = a1x − y − a3x 2 + (2a2 + a5)xy+a6y 2 , y ′ = x+a1y+a2x 2+(2a3+a4)xy−a2y 2 . In particular, we study the semi-varieties defined in terms of the parameters a1, a2, . . . , a6 where some classical criteria for the associated Abel equation apply. The proofs will combine classical ideas with tools from computational algebraic geometry.Agencia Estatal de Investigación - Fondo Europeo de Desarrollo Regional (grant MTM 2011-22751)Junta de Extremadura (grant GR15055)Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (grant MTM2015-65764-C3-1-P
