A semantic matching algorithm for discovery in UDDI
(IEEE, 2007) Aguilera, Unai; Abaitua, Joseba; Díaz Labrador, Josuka; Buján Carballal, David; López de Ipiña González de Artaza, Diego
One of the key objectives of web service technology is to construct processes that enable service providers to interconnect with their clients. The industry has developed the UDDI registry to enable the register of services and to make them available to their users. However, the keyword-based search of UDDI frequently return no results because there is no relation between the concepts used by the providers and those used by the clients. This paper presents an UDDI registry extended with semantic functionality by means of a generic semantic discovery algorithm that is not bound to any specific ontology or concepts from it. It enables to match instances and properties without specifically knowing the ontologies being matched. Furthermore, we present an ontology which represents the information associated with a business entity in UDDI, and which enables users to register and search business information semantically also using the former algorithm
A generic matching algorithm for semantic discovery
(IEEE, 2007) Aguilera, Unai; Abaitua, Joseba; Díaz Labrador, Josuka; Buján Carballal, David; López de Ipiña González de Artaza, Diego
This paper presents a generic semantic discovery algorithm, based in OWL, for UDDI registries that is not bound to any specific ontology or concepts from it. It enables to match instances and properties without specifically knowing the ontologies being matched and it enables to use all concepts contained in the request resulting in a matching closer to the user needs. Also, the generality of the proposed algorithm enables to change the ontology being used to describe an element in the registry without needing to modify the algorithm and therefore, it enables to use other OWL ontologies to describe the information stored in the registry
Interacting with the digital world through RFID-powered gadgets
(IEEE, 2009) Muguira Urtubi, Leire; Ruiz de Garibay Pascual, Jonathan; Vazquez, Juan-Ignacio
The Internet of Things is a field of the Future Internet that has a significant support from different institutions. Research has been done in this area for years and although it has progressed significantly, their goals remain the same: designing innovative Internet-connected experiences and augmenting existing objects' capabilities with Internet-related features. The scientific community has explored new ways and concepts, such as, service generation and consumption or user interaction. In this paper we present our work on creating RFID-based smart gadgets in order to take Internet experience to the next level, merging the on-line and the tangible worlds into a single continuous space.
RFIDGlove: a wearable RFID reader
(IEEE, 2009) Muguira Urtubi, Leire; Vazquez, Juan-Ignacio; Arruti, Asier; Ruiz de Garibay Pascual, Jonathan; Mendia, Izaskun; Renteria, Silvia
There are different experiences in the use of RFID technology for warehouse inventories. However, there is future work to do on the design of advanced reading devices, applying wearable computation techniques and wireless communications. The aim of this work is to allow a natural interaction for the user who performs inventory tasks. In this paper we show the RFIDGlove system, which consists of a glove with an integrated RFID reader, an organic micro display and a communication system. The RFIDGlove system increases the efficiency of the activities in these areas, improving the user's experience and comfort while he/she uses the system. © 2009 IEEE.
A model of non functional properties for grid resources
(Springer, 2009) Buján Carballal, David; Corcho García, Óscar; Díaz Labrador, Josuka
So far, Grid information providers basically give functional values about resources, although some of them also provide aggregated information. Therefore, existing Grid information models essentially represent this syntactic information and also propose different taxonomies of resources. Hence, Grid information consumers commonly use functional properties to select resources in order to send jobs to a Grid. There are some approaches that try to use isolated techniques to take into consideration some QoS properties, like performance. In this paper, we propose a unified model for representing Grid resources and their non functional properties, adding semantics to Grid information systems. On one hand, this model is an ontology-based model developed to integrate existing approaches of Grid information models and non functional properties representations in general. But on the other hand, our model also proposes a measuring system - currently in development - for some non functional properties like reliability, availability and performance. Here we only present an overview about how to represent and measure reliability information of resources in Grids. This example is used to illustrate our work in progress.
Internet browsing through RFID-powered gadgets
(IOS Press, 2009) Muguira Urtubi, Leire; Ruiz de Garibay Pascual, Jonathan; Vazquez, Juan-Ignacio
The vision of the Internet of Things is challenging researchers from different fields with the common goal of designing innovative Internet-connected experiences or augmenting existing objects' capabilities with Internet-related features. During these first stages, researchers must explore new ways and concepts, and share the results with the scientific community. In this paper, we present our work on creating RFID-based smart gadgets in order to take Internet experience to the next level, merging the on-line and the tangible worlds into a single continuous space.
An environment adaptive ZigBee-based indoor positioning algorithm
(IEEE, 2010) Larrañaga, Janire; Muguira Urtubi, Leire; López Garde, Juan Manuel; Vazquez, Juan-Ignacio
Lately, there has been significant progress in the field of wireless communications and networking. Furthermore, the number of applications that require context information as the user's location will increase in the coming years. However, this issue still has not been solved indoors due to the RF (Radio Frequency) signals' behaviour in this kind of scenarios. In this paper, we present a robust, easy to deploy and flexible indoor localization system based on ZigBee Wireless Sensor Networks. It is important to mention that our localization system is based on RSSI (Received Signal Strength Indicator) level measurements since this information can be obtained directly from the messages exchanged between nodes, so no extra hardware is required. Our localization system consists of two phases: calibration and localization. Anytime a blind node needs to be located, our system performs calibration using a matrices system, so that the environment can be characterized, taking into account possible changes on it since the last request. Then, in the localization phase, the central server processes all the information and calculates the blind node's position with the new iterative algorithm we present. With this indoor positioning algorithm we can estimate the blind node's position with a good resolution (3 m average error), so we can say that this ZigBee localization algorithm provides very promising results.
Architecture for WSN nodes integration in context aware systems using semantic messages
(Springer, 2010) Larizgoitia, Iker; Muguira Urtubi, Leire; Vazquez, Juan-Ignacio
Wireless sensor networks (WSN) are becoming extremely popular in the development of context aware systems. TraditionallyWSN have been focused on capturing data, which was later analyzed and interpreted in a server with more computational power. In this kind of scenario the problem of representing the sensor information needs to be addressed. Every node in the network might have different sensors attached; therefore their correspondent packet structures will be different. The server has to be aware of the meaning of every single structure and data in order to be able to interpret them.Multiple sensors, multiple nodes, multiple packet structures (and not following a standard format) is neither scalable nor interoperable. Context aware systems have solved this problem with the use of semantic technologies. They provide a common framework to achieve a standard definition of any domain. Nevertheless, these representations are computationally expensive, so a WSN cannot afford them. The work presented in this paper tries to bridge the gap between the sensor information and its semantic representation, by defining a simple architecture that enables the definition of this information natively in a semantic way, achieving the integration of the semantic information in the network packets. This will have several benefits, the most important being the possibility of promoting every WSN node to a real semantic information source. © 2010 ICST Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.
New approaches in context modelling for tourism applications
(Springer Berlin, 2012) Buján Carballal, David; Martín, David; Torices, Ortzi; Uriarte, Aritz
The notion of context has been widely studied and there are several authors that have proposed different definitions of context. However, context has not been widely studied in the framework of human mobility and the notion of context has been directly imported from other computing fields without specifically addressing the tourism domain requirements. In order to store and manage context information a context data model is needed. Ontologies have been widely used in context modelling, but many of them are designed to be applied in general ubiquitous computing environments, do not contain specific concepts related to the tourism domain or some approaches do not contain enough concepts to represent context information related to the visitor or tourist on the move as we need in the TourExp project. That is why we propose a new approach to provide a better solution to model context data in tourism environments, adding more value to our solution reusing Open Data about tourist resources from Open Data Euskadi initiative and publishing it as Linked Data
WebLab-Deployer: exporting remote laboratories as SaaS through federation protocols
(IEEE, 2013) Orduña Fernández, Pablo; Larrakoetxea, Xabier; Buján Carballal, David; Angulo Martínez, Ignacio; Dziabenko, Olga; Rodríguez Gil, Luis; López de Ipiña González de Artaza, Diego; García-Zubía, Javier
During the last decade, remote laboratories have been extensively used as a primary learning tool in many universities around the world. However, today most of the remote laboratories are still only used by the same institution that provides or even develops them, or by direct partners in federated environments. There are two ways to support this type of federation: a) using a federated authentication system such as Shibboleth or b) installing a remote laboratory management system that supports federation natively. In both cases, the consumer institution must go through a process of deployment or complex configuration. This contribution explores providing access to laboratories using a Cloud Computing approach, considering the federated environments that do not have laboratories attached as a SaaS (Software as a Service) system. This approach not only makes adoption by other institutions easier, but also benefits from the existing features provided by Cloud Computing, such as elasticity to reuse the same resources for different institutions to balance the load

¿Qué nuevas demandas educativas, investigadoras y de servicio a la sociedad de los alumnos mayores no están todavía incorporadas de manera generalizada en nuestra oferta formativa?: propuesta de la Universidad de Deusto: DeustoBide-Escuela de Ciudadanía
(Editorial Universidad de Granada, 2015) Lázaro Fernández, Yolanda
Es una realidad que cada vez son más las personas que llegan a edades más avanzadas en nuestro entorno y que lo hacen en condiciones notablemente mejores que en épocas anteriores. Actualmente la nueva generación de personas mayores que nos encontramos tiene una experiencia significativa y presentan posibilidades de mantenerse socialmente activas y participativas. Y uno de esos planos sociales de participación es el ámbito educativo. En todas las edades, la educación cumple una importante función socializadora y ayuda a establecer relaciones de pertenencia y de intercambio y esto no es distinto en las personas adultas mayores. Esta presentación trata de mostrar qué tipo de demandas presentan el millar de personas que acuden a las propuestas formativas que desde la Universidad de Deusto venimos desarrollando para un público adulto. Un recorrido de seis programas con duración y dedicación diferentes desarrollados a lo largo de veinte años y una marcada identidad jesuita son algunos de los rasgos que nos acompañan y que nos animan a seguir trabajando en el empoderamiento de la ciudadanía, para que sepamos hacer uso de las capacidades que en cada momento de la vida tenemos para vivir más plenamente tanto individual como colectivamente.
Algorithm development for night charging electric vehicles optimization in big data applications
(Elsevier B.V., 2017) Álvaro Hermana, Roberto ; Fraile Ardanuy, Jesús ; Merino, Julia
In this paper a night charging method that optimizes the recharging process of electric vehicles (EVs) depending on hourly energy price in a peer to peer (P2P) energy trading system is presented. This algorithm determines how much energy should be recharged in the battery of each EV and the corresponding time slot to do it, avoiding the discontinuities in the charging process and considering the users' personal mobility constraints.
The granular and fundamental components of export specialization
(Universidad Pablo de Olavide, 2017) Lucio Fernández, Juan José de ; Minondo, Asier ; Requena Silvente, Francisco ; Mínguez, Raúl
We propose an easy-to-implement methodology to determine the contribution of fundamental comparative advantage (a country-specific component) and granular comparative advantage (a firm-specific component) to export specialization. We apply this methodology to analyze export specialization across countries and across regions within a country. In the country-level analysis, we find that, on average, granular comparative advantage leads to export specialization in 29% of industries, which account for 47% of total exports. We also show that 60% of the variation in export specialization across countries is explained by granular comparative advantage. The contribution of granularity to export specialization is more important across regions within a country than across countries.
Collaborative Robots in e-waste management
(Elsevier B.V., 2017) Álvarez de los Mozos, Esther; Rentería Bilbao, Arantxa
Nowadays manufacturing companies are going through an increasing public and government pressure to reduce the environmental impact of their operations. But when dealing with e-waste, some difficulties arise in classifying and dismantling electronic devices. Manual operations are financially prohibitive and full automation is also discarded due to the lack of uniformity of the disposed devices. A halfway solution is to let a human operator and a robot share the process. The goal of this research is the optimization of the recycling process of electronic equipments, applying both technical and economic criteria, and taking into account the latest developments in collaborative robots.
BLUE care: a cooperative location network for handicapped persons
(Elsevier Ltd, 2017) Bahillo, Alfonso ; Díez Blanco, Luis Enrique ; Arambarri Soto, Ander
Many dependents such as children, elderly or disabled people get lost or missing, but as handicapped people, they often lack the skills to protect themselves, and tutors cannot keep their dependents in sight all of the time. Therefore, the challenge to be tackled in this paper is to develop a dependents' cooperative location network over which tutors could monitor the dependents' positions in real time, giving them more freedom to safely roam within public spaces. Not only in open spaces such as crowded parks or streets, but also inside buildings such as city malls, museums or nursing homes. The aim of this paper is twofold, to create a cooperative and dynamic network of tutors over which monitor the position of their dependents by means of standardized technologies, and to understand how the physical environment could influence handicapped people's activities by means of behavioral analysis in public spaces.
La promoción del pensamiento para la construcción de los aprendizajes en la formación inicial de los maestros de educación infantil y primaria
(Asociacion Interuniversitaria de Investigacion Pedagógica (AIDIPE), 2017-07) Gómez Barreto, Isabel María; Sánchez Santamaría, José ; Bilbao Quintana, Naiara
Aprender a pensar es el principal reto de la docencia. La evidencia empírica disponible indica la importancia de una Cultura del Pensamiento para favorecer procesos de aprendizaje exitosos, de modo que los estudiantes universitarios aprendan a ser conscientes de sobre qué aprenden y cómo aprenden. En este sentido, este trabajo muestra los resultados de un estudio de encuesta en estudiantes universitarios (n=218) de Educación Infantil y Primaria. El objetivo de este trabajo es identificar las percepciones que poseen los estudiantes acerca de la promoción del pensamiento para la construcción de los aprendizajes en su formación inicial como maestros. Los estudiantes informan de que no perciben una intención pedagógica en su formación que se oriente a la promoción de la cultura del pensamiento.

La performance del selfie del arte de la exhibición y sus públicos en tiempos de la mirada-flujo
(Universidade de Vigo, Servizo de Publicacións, 2019) Cuenca Amigo, Jaime
Las técnicas de producción de la auto-imagen han facilitado en la modernidad cauces privilegiados para la construcción de la propia identidad. Su actual proliferación a través de la fotografía de no ha hecho sino enfatizar esta función, transformando radicalmente sus condiciones. Frente al autorretrato tradicional, que ponía en escena a un sujeto sólido, autónomo e identificado por sus atributos específicos, en el el individuo tardomoderno ha pasado a ser poco más que una “marca de agua”, un signo de autenticidad que estampar sobre contenidos atractivos susceptibles de ser compartidos en redes sociales. A la luz de un análisis teórico de este ecosistema de la auto-imagen se analizarán aquí las propuestas de tres , que ponen el , precisamente, en el centro de su trabajo artístico y al hacerlo se ven sumidas en una dialéctica inevitable entre la figura del artista y del , la praxis crítica y el , el empoderamiento y la objetivación.
Proyecto de dirección y liderazgo.
(Universitat de Lleida, Ediciones de la Universidad de Lérida = Edicions de la Universitat de Lleida, 2019) Aguirregabiria Barturen, F. Javier; Ariceta Iraola, Maria Isabel
La legislación educativa española establece como requisito para el acceso a la dirección que todos los candidatos deben presentar un proyecto de Dirección que, en caso de ser elegidos, llevarán a la práctica en el centro. El contexto de cambio constante en que vive la sociedad hace que, también el centro educativo, se vaya convirtiendo en una organización flexible, adaptable y con capacidad de respuestas a los retos actuales. El liderazgo de la Dirección entendida como Equipo Directivo ejercerá como motor de cambio y transformación en los centros educativos (Pietsch y Tulowitzki, 2017; Sun y Leithwood, 2015). En esta investigación se observa el cambio que ha experimentado el estilo de liderazgo de los equipos directivos como consecuencia de la elaboración y posterior puesta en marcha y evaluación del Proyecto de Dirección.
