These were excavated by G.Bonsor in the Alcores's area in 1909 and they form part of a necropolis unknown up to now "Raso del Chirolí

Computation of moments for probabilistic finite-state automata

[EN] The computation of moments of probabilistic finite-state automata (PFA) is researched in this article. First, the computation of moments of the length of the paths is introduced for general PFA, and then, the computation of moments of the number of times that a symbol appears in the strings generated by the PFA is described. These computations require a matrix inversion. Acyclic PFA, such as word graphs, are quite common in many practical applications. Algorithms for the efficient computation of the moments for acyclic PFA are also presented in this paper.This work has been partially supported by the Ministerio de Ciencia y Tecnologia under the grant TIN2017-91452-EXP (IBEM), by the Generalitat Valenciana under the grant PROMETE0/2019/121 (DeepPattern), and by the grant "Ayudas Fundacion BBVA a equipos de investigacion cientifica 2018" (PR[8]_HUM_C2_0087).Sánchez Peiró, JA.; Romero, V.

Most of the research published so far on Bengali handwriting recognition deals with either isolated character recognition or isolated word recognition, and just a few papers have researched on recognition of continuous handwritten Bengali. In this paper we present a research on continuous handwritten Bengali. We follow a classical line-based recognition approach with a system based on hidden Markov models and n-gram language models. These models are trained with automatic methods from annotated data. We research both on the maximum likelihood approach and the minimum error phone approach for training the optical models. We also research on the use of word-based language models and characterbased language models. This last approach allow us to deal with the out-of-vocabulary word problem in the test when the training set is of limited size. From the experiments we obtained encouraging results.This work has been partially supported through the European Union’s H2020 grant READ (Recognition and Enrichment of Archival Documents) (Ref: 674943) and partially supported by MINECO/FEDER, UE under project TIN2015-70924-C2-1-R.Sánchez Peiró, JA.; Pal, U.

La educación audiovisual y la creación de prosumidores mediáticos. Estudio de caso

La Web 2.0 ofrece tecnologías que permiten a sus consumidores convertirse en prosumidores, consumidores de los productos generados por ellos mismos. En el marco de esta cultura participativa, muchos creadores profesionales de contenidos audiovisuales no están teniendo en cuenta la posibilidad de que sus consumidores se conviertan efectivamente en prosumidores, formando parte del propio proceso de producción audiovisual. Se presenta un estudio de caso basado en el trabajo de los alumnos de la asignatura «Tendencias del audiovisual contemporáneo» de 2º Grado de Publicidad y Relaciones Públicas de la Universitat de Girona. Los alumnos tuvieron que crear proyectos audiovisuales transmedia dirigidos a una audiencia de prosumidores que modificaron el contenido de los proyectos interactivamente. Con el objetivo de realizar un aprendizaje profundo de las tendencias audiovisuales actuales, se utilizó una metodología innovadora: hacer que el estudiante se dirija a un prosumidor mediático. Su alfabetización digital progresó con el uso de las herramientas en un entorno real. Los alumnos crearon proyectos audiovisuales con emisión transmedia y ampliaron su conocimiento de las tendencias audiovisuales de los prosumidores de los medios. El rol de los alumnos como creadores de contenidos dirigidos a prosumidores mediáticos provocó un alto grado de implicación en la creación audiovisual, en su aprendizaje y en el enriquecimiento de las experiencias de los usuarios. Los alumnos mostraron su interés con el contenido y el planteamiento docente de la asignatura.Web 2.0 offers technologies that allow consumers become prosumers, consumers of the products generated by them. As part of this participatory culture, many professional audiovisual content creators are not taking into account the possibility that consumers will actually become prosumers, as part of the process of audiovisual production. A case study based on the work of students in the course «Trends in contemporary audiovisual» 2nd Degree in Advertising and Public Relations at the University of Girona is presented. Students had to create transmedia audiovisual projects to an audience of prosumers that modified interactively the content of the projects. In order to conduct thorough visual learning current trends, an innovative methodology was used: make the student to address a media prosumer. Their digital literacy progressed using the tools in a real environment. Students created audiovisual broadcast and transmedia projects and expanded their knowledge of audiovisual trends of media prosumers. The role of students as creators of media content aimed at prosumers caused a high degree of involvement in the audiovisual creation, in their learning and in the enrichment experiences for users. Students showed interest in the content and teaching approach to the subject

El Transmedia Audiovisual en el aula universitaria

Asistimos a una nueva manera de distribuir los contenidos a través de múltiples plataformas. En el contexto actual, la narración ha dejado de producirse en exclusiva para un medio audiovisual concreto, para empezar a hacerlo a través de varios y complementarios medios o plataformas. Por ello, el diseño de este tipo de narrativas debe ser incluido en los proyectos docentes universitarios que trabajen con estudiantes del área de la Comunicación Audiovisual, la Publicidad y el Periodismo. Presentamos un caso de estudio real en el que los alumnos de una asignatura de cuarto curso del grado de Comunicación Audiovisual en la Universitat Autònoma de Barcelona, diseñan y producen una narrativa transmedia de ficción con distribución de contenidos a través de web, red social, televisión y aplicación móvil propia. El resultado de este proyecto es la distribución profesional de diez narrativas audiovisuales transmedia, realizadas por estudiantes universitarios y dirigidas a prosumidores reales actuale

Practical application of mesh opportunistic networks

This research was funded by Department of Technological Innovation of Institute RTVE (Spanish Public Television, RTVE), the Almagro Classical Theater Festival and Observatory for News Innovation in the Digital Society (OI2).Opportunistic networks allow for communication between nearby mobile devices through a radio connection, avoiding the need for cellular data coverage or a Wi-Fi connection. The limited spatial range of this type of communication can be overcome by using nodes in a mesh network. The purpose of this research was to examine a commercial application of electronic mesh communication without a mobile data plan, Wi-Fi, or satellite. A mixed study, with qualitative and quantitative strategies, was designed. An experimental session, in which participants tested opportunistic networks developing different tasks for performance, was carried out to examine the system. Different complementary approaches were adopted: a survey, a focus group, and an analysis of participants' performance. We found that the main advantage of this type of communication is the lack of a need to use data networks for one-to-one and group communications. Opportunistic networks can be integrated into professional communication workflows. They can be used in situations where traditional telephones and the Internet are compromised, such as at mass events, emergency situations, or in the presence of frequency inhibitors

La intervención sobre la brecha salarial entre hombres y mujeres. Análisis de barreras institucionales, organizacionales y culturales

La comunicación trata de poner de relieve y analizar algunos de los principales elementos que dificultan la implementación y eficacia de políticas públicas orientadas a la reducción de la Brecha Salarial entre hombres y mujeres. Se presentan resultados preliminares del proyecto I+D BridgeS,que pone el foco en el modo en que distintos contextos y culturas organizativas pueden favorecer o constituir barreras para dichas políticas. Se analizan datos de la Encuesta de Estructura Salarial,para evidenciar la heterogeneidad de patrones que dibuja la Brecha para distintos colectivos dentro del mercado de trabajo. Argumentando la pertinencia de tomar el sector de actividad como espacio privilegiado de análisis y de implementación de políticas, se construye una tipología de sectores representativa de la diversidad de contextos de empleo de las mujeres. Con base en dicha tipología, se presenta la selección de sectores clave para su análisis en profundidad, junto con un primer análisis exploratorio. Se finaliza con algunas reflexiones acerca de las barreras y dificultades para la intervención pública en este ámbito
