Visual Localisation of Mobile Devices in an Indoor Environment under Network Delay Conditions

Current progresses in home automation and service robotic environment have highlighted the need to develop interoperability mechanisms that allow a standard communication between the two systems. During the development of the DHCompliant protocol, the problem of locating mobile devices in an indoor environment has been investigated. The communication of the device with the location service has been carried out to study the time delay that web services offer in front of the sockets. The importance of obtaining data from real-time location systems portends that a basic tool for interoperability, such as web services, can be ineffective in this scenario because of the delays added in the invocation of services. This paper is focused on introducing a web service to resolve a coordinates request without any significant delay in comparison with the sockets

Misalignment & Co.: (Pseudo-)scalar and vector dark matter with curvature couplings

Motivated by their potential role as dark matter, we study the cosmological evolution of light scalar and vector fields non-minimally coupled to gravity. Our focus is on a situation where the dominant contribution to the energy density arises from the misalignment mechanism. In addition, we also discuss the possibility that dark matter is generated in a stochastic scenario or from inflationary fluctuations. Even small deviations in the non-minimal couplings from the standard scenarios lead to significant qualitative and quantitative changes. This is due to the curvature-coupling driven superhorizon evolution of the homogeneous field and the non-zero momentum modes during inflation. Both the relic density yield and the large-scale density fluctuations are affected. For the misalignment mechanism, this results in a weakening of the isocurvature constraints and opens up new viable regions of parameter space.Comment: 25 pages, 8 figures.

Integrated practices: an example of educational innovation and cooperation in the current European Higher Education Area

Tras la última Reforma Universitaria –en la cual se estableció la creación del Espacio Europeo de Educación Superior y el llamado Plan Bolonia–, se ha hecho obligatorio e imprescindible el uso de prácticas en la totalidad de los nuevos títulos de grado. Si bien es cierto que se trata de actividades tradicionales y de gran importancia en las titulaciones del ámbito científico, tanto para adquirir conocimientos como actitudes, su uso resulta más complejo que en otro tipo de titulaciones. Tal es el caso del Grado de Maestro en Educación Primaria, donde el perfil del alumno, su formación inicial y su futuro profesional hacen difícil el uso de las prácticas con resultados óptimos. Añadido a lo anterior, la falta de tiempo y las numerosas materias a impartir en ese reducido número de clases, hace que su uso quede muchas veces reducido a experiencias tradicionales y de baja significación para el tipo de alumnado al que van dirigidas. Por ello en el presente estudio se tratará de abordar en primer lugar la importancia de las que pueden denominarse como prácticas integradas y cómo gracias a ellas se podría atender a las diferentes materias científicas de manera interconectada y eficaz en el marco de una única actividad práctica global. Con el fin de analizar su efectividad en el citado grado de Educación Primaria pueden tomarse como referencia varias asignaturas, entre las cuales una de las más atractivas es la de Desarrollo Curricular de las Ciencias Experimentales. Esto supondrá una innovación dentro de los planes de estudio cada vez más saturados y permitirá una docencia más acorde al paradigma de aprendizaje significativo dentro de la formación de futuros docentes de educación primaria. Como segundo objetivo del trabajo se ejemplificará una práctica integral y su análisis y adecuación a los objetivos académicos, junto con su posible desarrollo en el aula..After the last university reform which established the creation of the European Higher Education Area and the called Bologna Process, it has become imperative and essential the use of practices in all the new degrees. While the practices are a traditional and important activities in the scientific qualifications, both to acquire knowledge and attitudes, their use is more complex in other types of degrees. Such is the case of Degree in Elementary Education Teacher, where the student's profile, their initial training and professional future make it difficult to use the practices with optimums results. Added to this, insufficient time and the many subjects to be taught at the reduced number of classes, makes their use be reduced in many times to a traditional experiences with poorly significance for the type of students to whom they are addressed. Thus in the present study will seek to address firstly the importance of which can be termed as integrated practices and how they could be due to respond to the various scientific subjects, both effective and interconnected, under a single global practice activity. In order to analyze its effectiveness in that degree of Primary Education Teacher can be referenced several subjects, including one of the most attractive is the Curricular Development of Experimental Science. This will be an innovation in the curriculum increasingly saturated and allow teaching according to the paradigm of significant learning in the training of future Primary School teachers. The second objective of the work will be exemplified an integral practice and analysis and adjustment to academic objectives, along with their possible development in the classroom

Hypogravity research and educational parabolic flight activities conducted in Barcelona: a new Hub of innovation in Europe

We report on different research and educational activities related to parabolic flights conducted in Barcelona since 2008. We use a CAP10B single-engine aerobatic aircraft flying out of Sabadell Airport and operating in visual flight conditions providing up to 8 seconds of hypogravity for each parabola. Aside from biomedical experiments being conducted, different student teams have flown in parabolic flights in the framework of the international contest ‘Barcelona Zero-G Challenge’, and have published their results in relevant symposiums and scientific journals. The platform can certainly be a good testbed for a proof-of-concept before accessing other microgravity platforms, and has proved to be excellent for motivational student campaigns.Peer ReviewedPostprint (author's final draft

Una lectura filológico-lingüística de la encíclica "Laudato si". Reflexiones en torno a los conceptos de uso, dominio y propiedad

El objetivo de la presente publicación es el de contribuir a los estudios en torno a los conceptos de uso, dominio y propiedad en el ámbito de la reflexión sobre la antropología de la economía en la Escuela de Salamanca. En la medida en que hablamos de signos lingüísticos dinámicos tanto en su significante como en su significado, proponemos la necesidad de elaborar un estudio diacrónico de tales términos desde su significado etimológico hasta su uso en la actualidad. Este eje de evolución cronológica debería servir de referente para que otras disciplinas como la filosofía, la historia del derecho, etc. valoren la desviación semántica que supone la utilización de uso, dominio y propiedad como terminología en un contexto concreto y en una época determinada.The main target of the current paper is contributing to the study about the concepts of usage, domain and property on the field of reflexion about Economy's Anthropology in the School of Salamanca. As far as we refer to dynamic linguistic signs, considering both signifier and significance, we recommend the production of a diachronic study of such terms from their ethimological meaning to its present usage. This central concept of chronological evolution should be an example of assessment of semantic digression (in other disciplines such as Phylosophy, History of Law, etc) when using the previously mentioned terms of usage, domain and property as terminology in a specific context and a certain time.peerReviewe

La cronología del tránsito Magdaleniense / Aziliense en la región cantábrica

El final del Paleolítico coincide con un cambio climático importante, el final del Pleistoceno y de la era cuaternaria y el comienzo del Holoceno. En la región cantábrica ese momento está marcado por el tránsito entre dos culturas que presentan al mismo tiempo continuidad y gran diferencia. El proceso de microlitización que comienza en el Magdaleniense tiene su punto álgido durante los primeros momentos del Epipaleolítico, en concreto durante el Aziliense. Resumiendo la información disponible, en este artículo se trata de asignar una cronología al momento del cambio entre ambos mundos, el Magdaleniense y el Aziliense, en el norte de la Península Ibérica Ibérica.The end of the Palaeolithic coincides with an important climatic change: the end of the Pleistocene and the Quaternary, which give way to the Holocene. This moment is marked in the Cantabrian region of Spain by the transition between two cultures. This transition is not abrupt, but the cultures are very different. The process of increasing abundance of microliths, which starts in the Magdalenian, has its best expression during the first phases of the Epipaleolithic, more specifically during the Azilian. In this paper, we present a chronology for the moment of change from one world to the other, from the Magdalenian to the Azilian, in the northern Iberian Peninsula
