    The urban heritage characterization using 3D geographic information systems. The system of medium-sized cities in Andalusia

    Get PDF
    The primary objective of this paper is to approach the use of the 3D Geographic Information Systems (3D GIS), as an instrumental tool that allows us to deal efficiently with the extensive amount of information that characterises a large part of the research carried out in the field of Urbanism and Regional Planning. Specifically, the study focuses on medium-sized cities in Andalusia, the most populous and the second largest region in Spain. The Andalusian urban system is substantially characterised by the historical importance of this type of cities within its territorial organisation, which dates back to more than two thousand years, and whose potential as sustainable and balanced stands out. In particular, it is intended to address features related to urban characterisation as medium-sized cities that have been declared as heritage sites, as well as, the integration of the cultural heritage into urban development planning as an active strategy by the cultural administration of the regional and local governments. In detail, this paper will analyse data relating to the development experienced, their characterisation through urban indicators or the evolution and traceability of their protection. In this sense, the use of 3D GIS will not only allow the efficient recording and the graphical representation of a significant amount of data resulting from the quantitative and qualitative analysis carried out but also model them using the third dimension to facilitate a cross analysis among the cities under study. Definitely, the aim is to demonstrate the suitability use of this technology in this type of scientific research.Ministry of Economy and Competitiveness of the Government of Spain HAR2016-79788-

    Comportamiento dieléctrico de mezclas líquidas de carvacrol + alcohol de cadena corta

    Get PDF
    El Carvacrol C10H14O es un monoterpenoide fenólico que se encuentra en los aceites esenciales de diversas plantas, entre las que destaca el orégano y el tomillo. Desde el punto de vista de su posible extracción con CO2 supercrítico y de la miscibilidad de dichos extractos, es fundamental conocer el comportamiento dieléctrico de mezclas líquidas de Carvacrol con un segundo componente que, en el presente Trabajo de Fin de Grado, serán dos alcoholes de cadena corta: Etanol y 1-Propanol.Desde un punto de vista teórico, en este tipo de mezclas se van a producir roturas y formaciones de uniones por puentes de hidrógeno de manera que se intentarán relacionar los resultados del comportamiento dieléctrico con el orden local a nivel microscópico. Todo ello se llevará a cabo con la determinación de la permitividad dieléctrica, el índice de refracción y la densidad de las mezclas binarias Carvacrol + Etanol y Carvacrol + 1-Propanol a cuatro temperaturas, cubriendo todo el intervalo de composición para posteriormente calcular el factor de correlación de Kirkwood-Frölich e interpretar los resultados obtenidos.<br /

    Dose-dependent differential effect of neurotrophic factors on in vitro and in iivo regeneration of motor and sensory neurons

    Although peripheral axons can regenerate after nerve transection and repair, functional recovery is usually poor due to inaccurate reinnervation. Neurotrophic factors promote directional guidance to regenerating axons and their selective application may help to improve functional recovery. Hence, we have characterized in organotypic cultures of spinal cord and dorsal root ganglia the effect of GDNF, FGF-2, NGF, NT-3, and BDNF at different concentrations on motor and sensory neurite outgrowth. In vitro results show that GDNF and FGF-2 enhanced both motor and sensory neurite outgrowth, NGF and NT-3 were the most selective to enhance sensory neurite outgrowth, and high doses of BDNF selectively enhanced motor neurite outgrowth. Then, NGF, NT-3, and BDNF (as the most selective factors) were delivered in a collagen matrix within a silicone tube to repair the severed sciatic nerve of rats. Quantification of Fluorogold retrolabeled neurons showed that NGF and NT-3 did not show preferential effect on sensory regeneration whereas BDNF preferentially promoted motor axons regeneration. Therefore, the selective effects of NGF and NT-3 shown in vitro are lost when they are applied in vivo, but a high dose of BDNF is able to selectively enhance motor neuron regeneration both in vitro and in vivo

    SensorCloud: Towards the Interdisciplinary Development of a Trustworthy Platform for Globally Interconnected Sensors and Actuators

    Get PDF
    Although Cloud Computing promises to lower IT costs and increase users' productivity in everyday life, the unattractive aspect of this new technology is that the user no longer owns all the devices which process personal data. To lower scepticism, the project SensorCloud investigates techniques to understand and compensate these adoption barriers in a scenario consisting of cloud applications that utilize sensors and actuators placed in private places. This work provides an interdisciplinary overview of the social and technical core research challenges for the trustworthy integration of sensor and actuator devices with the Cloud Computing paradigm. Most importantly, these challenges include i) ease of development, ii) security and privacy, and iii) social dimensions of a cloud-based system which integrates into private life. When these challenges are tackled in the development of future cloud systems, the attractiveness of new use cases in a sensor-enabled world will considerably be increased for users who currently do not trust the Cloud.Comment: 14 pages, 3 figures, published as technical report of the Department of Computer Science of RWTH Aachen Universit

    Normative Emotional Agents: a viewpoint paper

    Get PDF
    [EN] Human social relationships imply conforming to the norms, behaviors and cultural values of the society, but also socialization of emotions, to learn how to interpret and show them. In multiagent systems, much progress has been made in the analysis and interpretation of both emotions and norms. Nonetheless, the relationship between emotions and norms has hardly been considered and most normative agents do not consider emotions, or vice-versa. In this article, we provide an overview of relevant aspects within the area of normative agents and emotional agents. First we focus on the concept of norm, the different types of norms, its life cycle and a review of multiagent normative systems. Secondly, we present the most relevant theories of emotions, the life cycle of an agent¿s emotions, and how emotions have been included through computational models in multiagent systems. Next, we present an analysis of proposals that integrate emotions and norms in multiagent systems. From this analysis, four relationships are detected between norms and emotions, which we analyze in detail and discuss how these relationships have been tackled in the reviewed proposals. Finally, we present a proposal for an abstract architecture of a Normative Emotional Agent that covers these four norm-emotion relationships.This work was supported by the Spanish Government project TIN2017-89156- R, the Generalitat Valenciana project PROMETEO/2018/002 and the Spanish Goverment PhD Grant PRE2018-084940.Argente, E.; Del Val, E.; Pérez-García, D.; Botti Navarro, VJ.

    Teaching innovation through the occupation of public space: urban heritage and planning at the University of Seville

    Get PDF
    Public space is one of the ventricles of the city - the engine that drives the social relations among the citizens who inhabit it - being able to contract or expand the spatial sequence within the contemporary city. As an inherent part of society, it evolves at the rate that collective behaviour dictates, forming a relationship of vital dependency [1]. In this society-space symbiosis, the architect's task from a polyhedral point of view is to provide the city with a spatial network that not only fills the relationship between individuals, but also emphasizes the sense of belonging to the place and the collective. In many cases throughout history and from an international point of view, public space, specifically the square as the social agora, has been an escape route for social, political and cultural demands and manifestations. Despite its crucial importance in historiography and social evolution, the share of this concept in the current teaching plans of the Department of Urban Planning and Territorial Planning of the University of Seville is nil, barely treated from the formal point of view in the subject "Public Space in Planning Urbanization". Objectives of the research: It is intended to put into practice the occupation of public space from the subject of "Urban Heritage and Planning" during the next academic year 2018-2019, with the primary objective of highlighting how the different ways of occupying, positioning oneself, moving about and conquering public space are directly related to the intentions of the claims, the character of the group that calls for them and the socio-political governing system [2]. For this reason, ephemeral occupations of public space in the city of Seville will be proposed as practices associated with the core argument of the subject, based on experiences developed by the School of Architecture of the University of Valparaiso (Chile). Around these occupations, the gender conflict applied to the historic city will be discussed, explaining how the starting urban elements constitute favourable or unfavourable parameters in terms of security, belonging, identity and habitability

    Exploring Partners for the Domino α‐Arylation/Michael Addition Reaction Leading to Tetrahydroisoquinolines

    Get PDF
    Sulfonates, sulfonamides, and phosphonates have proven useful nucleophiles for palladium‐catalyzed intramolecular α‐arylation reactions leading to tetrahydroisoquinolines. Although the sulfonate α‐arylation reaction can be successfully combined in a domino process with a broad range of Michael acceptors, only vinyl sulfones can be used in Michael additions when starting from sulfonamides. No domino process was developed with the phosphonate derivative. DFT calculations were carried out to gain more insights into the experimental differences observed in the reactions involving these substrates

    Tercer Sector : De invitado a imprescindible en la gestión de bienestar

    Get PDF
    Las entidades prestadoras de Servicios Sociales se han hecho imprescindible en las últimas décadas, como consecuencia de la expansión de modelo de política social mediterráneo caracterizado por la reducción del gasto social, la implicación de la familia como sustento de las políticas de bienestar y el incremento en la presencia cotidiana de distintas organizaciones del Tercer Sector con objeto de mantener los niveles de calidad de vida en la población. Esto no ha sido fácil, porque España ha pasado por un periodo de recesión cuyas principales víctimas han sido las personas. El Estado ha implementado políticas de recorte de gasto y ello ha afectado a los prestadores de servicios y en definitiva a la calidad de los Servicios Sociales
