El Instituto Oftálmico en la prensa madrileña desde su fundación hasta la Guerra Civil Española

La presente tesis doctoral es un análisis de la presencia en la prensa española del Instituto Oftálmico Nacional (IO) desde su fundación hasta la Guerra Civil española. Se pretende subrayar la importancia y el carácter pionero del Instituto en el campo de la Oftalmología española, además de enfatizar las vicisitudes por las que atravesó la institución médico-sanitaria y social en sus inicios, así como en la contienda. Asimismo, consideramos que con este trabajo contribuimos a exponer la historia de una institución tan importante como relativamente desconocida fuera del ámbito oftalmológico en nuestro país..

Mediante la topología de redes propuesta, se ha desarrollado un ejercicio práctico utilizando los softwares GNS3 y VirtualBox. Inicialmente se construye la red con componentes CISCO, y se hace la configuración de los dispositivos utilizados (router, switch, PC). La conexión se realiza de acuerdo a la tabla de enrutamiento, en la cual se han utilizado algunos valores que coinciden con los tres últimos dígitos de la cédula. Para dividir la accesibilidad de los usuarios, se utiliza el enrutamiento VRF asignando usuarios especiales y usuarios generales, todo implementado mediante los diferentes comandos aplicables en GNS3. De igual forma, se asignan las rutas estáticas en los router, para entablar la comunicación y permitir el flujo de datos, con la conmutación de accesibilidad planteada. La configuración realizada en la red, plantea como base, el uso de los conocimientos en electrónica y el desarrollo de los cursos en redes para CCNP, incluyendo los parámetros de seguridad para la correcta operación.Through the proposed network topology, a practical exercise has been developed using the GNS3 and VirtualBox software. Initially, the network is built with CISCO components, and the configuration of the devices used (router, switch, PC) is done. The connection is made according to the routing table, in which some values have been used that coincide with the last three digits of the ID. To divide the accessibility of users, VRF routing is used assigning special users and general users, all implemented through the different applicable commands in GNS3. In the same way, the static routes are assigned in the routers, to establish communication and allow the flow of data, with the accessibility switching proposed. The configuration carried out in the network, raises as a basis, the use of knowledge in electronics and the development of network courses for CCNP, including the security parameters for correct operation

HAKA: HierArchical Knowledge Acquisition in a sign language tutor

Communication between people from different communities can sometimes be hampered by the lack of knowledge of each other's language. A large number of people needs to learn a language in order to ensure a fluid communication or want to do it just out of intellectual curiosity. To assist language learners' needs tutor tools have been developed. In this paper we present a tutor for learning the basic 42 hand configurations of the Spanish Sign Language, as well as more than one hundred of common words. This tutor registers the user image from an off-the-shelf webcam and challenges her to perform the hand configuration she chooses to practice. The system looks for the configuration, out of the 42 in its database, closest to the configuration performed by the user, and shows it to her, to help her to improve through knowledge of her errors in real time. The similarities between configurations are computed using Procrustes analysis. A table with the most frequent mistakes is also recorded and available to the user. The user may advance to choose a word and practice the hand configurations needed for that word. Sign languages have been historically neglected and deaf people still face important challenges in their daily activities. This research is a first step in the development of a Spanish Sign Language tutor and the tool is available as open source. A multidimensional scaling analysis of the clustering of the 42 hand configurations induced by Procrustes similarity is also presented.This work has been partially funded by the Basque Government, Spain, under Grant number IT1427-22; the Spanish Ministry of Science (MCIU), the State Research Agency (AEI), the European Regional Development Fund (FEDER), under Grant number PID2021-122402OB-C21 (MCIU/AEI/FEDER, UE); and the Spanish Ministry of Science, Innovation and Universities, under Grant FPU18/04737.

Ostensive gestures come first: Their role in the beginning of shared reference

In developmental psychology pointing gestures are widely accepted as the gesture that par excellence allows shared reference (Cyrulnik, 2002; Liszkowski, Carpenter, Striano, & Tomasello, 2006), and as the basic form of gestural reference (Leavens, Hopkins & Bard, 2008; Pika, 2008). However, in semiotics, it is ostensive gestures that are considered to be the first instance of active signification, that is, gestures where an object occupies a prominent place as an instrument of communication (Eco, 1976). In this paper, coming from the pragmatics of the object perspective (Rodríguez & Moro, 1998), we argue that it is not pointing but ostensive gestures that come first. Specifically, we argue that: (1) osten- sive gestures are gestures; (2) a developmental understanding of gestures suggests that children understand and produce ostensive gestures before pointing gestures, and adults produce ostensive gestures with objects in a shared space with the child at a very early age long before pointing gestures; (3) a theoretical and pragmatic conceptualization of objects beyond their “physical” level is required. Objects are cultural products with public func- tions; as a consequence, objects are also powerful instruments of communication between people, especially during the first years of life, and not simply the setting that surrounds the communicative event. Finally, we discuss the implications of these notions for devel- opmental psychology, going beyond the declarative and imperative functions. We discuss three new functions of ostensive gestures: (1) for oneself with an exploratory and/or con- templative function, (2) private with a self-regulatory function in order to solve a problem, and (3) to another with an interrogative functio

RANSAC for Robotic Applications: A Survey

Random Sample Consensus, most commonly abbreviated as RANSAC, is a robust estimation method for the parameters of a model contaminated by a sizable percentage of outliers. In its simplest form, the process starts with a sampling of the minimum data needed to perform an estimation, followed by an evaluation of its adequacy, and further repetitions of this process until some stopping criterion is met. Multiple variants have been proposed in which this workflow is modified, typically tweaking one or several of these steps for improvements in computing time or the quality of the estimation of the parameters. RANSAC is widely applied in the field of robotics, for example, for finding geometric shapes (planes, cylinders, spheres, etc.) in cloud points or for estimating the best transformation between different camera views. In this paper, we present a review of the current state of the art of RANSAC family methods with a special interest in applications in robotics.This work has been partially funded by the Basque Government, Spain, under Research Teams Grant number IT1427-22 and under ELKARTEK LANVERSO Grant number KK-2022/00065; the Spanish Ministry of Science (MCIU), the State Research Agency (AEI), the European Regional Development Fund (FEDER), under Grant number PID2021-122402OB-C21 (MCIU/AEI/FEDER, UE); and the Spanish Ministry of Science, Innovation and Universities, under Grant FPU18/04737

Video camera surveillance could benefit greatly from advances in this field. In the area of robotics, the tasks of autonomous navigation or social interaction could also take advantage of the knowledge extracted from live video recording. In this paper, a new approach for video action recognition is presented. The new technique consists of introducing a method, which is usually used in Brain Computer Interface (BCI) for electroencephalography (EEG) systems, and adapting it to this problem. After describing the technique, achieved results are shown and a comparison with another method is carried out to analyze the performance of our new approach.This work has been partially funded by the Basque Government, Research Teams grant number IT900-16, ELKARTEK 3KIA project KK-2020/00049, and the Spanish Ministry of Science (MCIU), the State Research Agency (AEI), and the European Regional Development Fund (FEDER), grant number RTI2018-093337-B-I100 (MCIU/AEI/FEDER, UE).

Aprendizaje basado en proyectos (PBL) aplicado a la docencia de sistemas tecnológicos de última generación

El planteamiento general de la docencia de asignaturas cuyo contenido es eminentemente tecnológico, presenta el reto del constante y rápido cambio asociado a los avances en desarrollo tecnológico. Dentro de este contexto, se plantea emplear un método basado en la generación de herramientas que permitan un seguimiento autónomo de los cambios frente a opciones más descriptivas del estado actual de los sistemas estudiados. Sobre esta base, se estudia la idoneidad de un contexto basado en el desarrollo de proyectos que, si bien tienen necesariamente que abordar una temática particular, supone una forma a priori interesante de generar las habilidades necesarias para el aprendizaje autónomo y continuado
