Collaborative filtering recommender systems contribute to alleviating the problem of information overload that exists on the Internet as a result of the mass use of Web 2.0 applications. The use of an adequate similarity measure becomes a determining factor in the quality of the prediction and recommendation results of the recommender system, as well as in its performance. In this paper, we present a memory-based collaborative filtering similarity measure that provides extremely high-quality and balanced results; these results are complemented with a low processing time (high performance), similar to the one required to execute traditional similarity metrics. The experiments have been carried out on the MovieLens and Netflix databases, using a representative set of information retrieval quality measures.

This paper presents a CMOS temperature sensor based on the thermal dependencies of the leakage currents targeting the 65 nm node. To compensate for the effect of process fluctuations, the proposed sensor realizes the ratio of two measures of the time it takes a capacitor to discharge through a transistor in the subthreshold regime. Furthermore, a novel charging mechanism for the capacitor is proposed to further increase the robustness against fabrication variability. The sensor, including digitization and interfacing, occupies 0.0016 mm2 and has an energy consumption of 47.7–633 pJ per sample. The resolution of the sensor is 0.28 °C, and the 3σ inaccuracy over the range 40–110 °C is 1.17 °C.

La evolución de Internet al modelo Web 2.0, ha creado el nuevo sistema denominado Social Media, donde han proliferado un número ingente de redes sociales, que han cambiado las formas de relación y colaboración entre los usuarios, así como la relaciones de éstos y las empresas. En respuesta a estos dramáticos cambios sociales y tecnológicos, que actualmente están dando forma a las relaciones negocio-empresa, las empresas están descubriendo que es necesario modificar la estrategia de utilización del CRM (Customer Relationship Management) con sus clientes y desarrollar nuevas capacidades que permitan la creación de valor con los clientes. Y es aquí donde aparece el concepto de Social CRM, entendido como una estrategia centrada en entender, anticiparse y responder mejor a las necesidades de los clientes existentes o potenciales, aprovechando los datos sociales, para crear unas fuertes relaciones beneficiosas para ambas partes. En este trabajo se describe un modelo de adopción de Social CRM, aplicando un método de análisis “Top-Down”, y basado en el modelo de Gartner denominado “The Eight Building Blocks of CRM” [1]. El presente trabajo descompone el modelo de adopción descrito por Gartner, en los siguientes puntos. - Una decisión estratégica de la compañía - Asomarse a la realidad social - Analizar las redes sociales. - Metodología de adopción. - Despliegue y extensión en todos los departamentos de la compañía y la adaptación de los recursos humanos. - Selección e integración con las plataformas tradicionales de CRM - Análisis de herramientas de monitorización de Social CRM El modelo propuesto tiene dos objetivos, por un lado pretende proporcionar la visión de cómo CRM puede influir en los resultados empresariales en la era del cliente social, y por otro, proporcionar a los administradores cómo las inversiones y los recursos existentes de CRM puede ser integrados con las nuevas tecnologías y procesos para formar capacidades que pueden mejorar el rendimiento del negocio. ABSTRACT. “The Internet evolution to Web 2.0 model has created a new system called Social Media, where have proliferated a huge number of social networks which have changed the relationship and collaboration forms user-to-user and user-to-company. In response to these dramatic social and technological changes that are currently shaping the business-business relationships, companies are finding it necessary to modify the strategy for use of CRM (Customer Relationship Management) with customers and develop new capabilities to creating value with customers. And here is where the concept of Social CRM appears, understood as a focus on understanding, anticipating and responding to the needs of existing and potential customers strategy, leveraging social data to create a strong mutually beneficial relationships. In this paper describes an adoption model of Social CRM, using a "Top-Down" analysis method and based on the model of Gartner called "The Eight Building Blocks of CRM" [1]. This paper decomposes the adoption model described by Gartner in the following points. - A company strategic decision. - Look at social reality. - Analyze social networks. - Methodology adoption. - Deployment and extension in all departments of the company and the adaptation of human resources. - Selection and integration with traditional CRM platforms. - Analysis of monitoring tools for Social CRM. The proposed model has two objectives, firstly aims to provide insight into how CRM can influence business outcomes in the era of the social customer, and secondly, to provide administrators how investments and existing resources can be integrated CRM with new technologies and processes for developing capabilities that can increase business performance”.

ML 1.4 is widely accepted as the standard for representing the various software artifacts generated by a development process. For this reason, there have been attempts to use this language to represent the software architec- ture of systems as well. Unfortunately, these attempts have ended in representa- tions (boxes and lines) already criticized by the software architecture commu- nity. Recently, OMG has published a draft that will constitute the future UML 2.0 specification. In this paper we compare the capacities of UML 1.4 and UML 2.0 to describe software architectures. In particular, we study extensions of both UML versions to describe the static view of the C3 architectural style (a simplification of the C2 style). One of the results of this study is the difficulties found when using the UML 2.0 metamodel to describe the concept of connector in a software architecture.

A validation of the burn-up simulation system EVOLCODE 2.0 is presented here, involving the experimental measurement of U and Pu isotopes and some fission fragments production ratios after a burn-up of around 30 GWd/tU in a Pressurized Light Water Reactor (PWR). This work provides an in-depth analysis of the validation results, including the possible sources of the uncertainties. An uncertainty analysis based on the sensitivity methodology has been also performed, providing the uncertainties in the isotopic content propagated from the cross sections uncertainties. An improvement of the classical Sensitivity/ Uncertainty (S/U) model has been developed to take into account the implicit dependence of the neutron flux normalization, that is, the effect of the constant power of the reactor. The improved S/U methodology, neglected in this kind of studies, has proven to be an important contribution to the explanation of some simulation-experiment discrepancies for which, in general, the cross section uncertainties are, for the most relevant actinides, an important contributor to the simulation uncertainties, of the same order of magnitude and sometimes even larger than the experimental uncertainties and the experiment- simulation differences. Additionally, some hints for the improvement of the JEFF3.1.1 fission yield library and for the correction of some errata in the experimental data are presented.

La web vive un proceso de cambio constante, basado en una interacción mayor del usuario. A partir de la actual corriente de paradigmas y tecnologías asociadas a la web 2.0, han surgido una serie de estándares de gran utilidad, que cubre la necesidad de los desarrollos actuales de la red. Entre estos se incluyen los componentes web, etiquetas HTML definidas por el usuario que cubren una función concreta dentro de una página. Existe una necesidad de medir la calidad de dichos desarrollos, para discernir si el concepto de componente web supone un cambio revolucionario en el desarrollo de la web 2.0. Para ello, es necesario realizar una explotación de componentes web, considerada como la medición de calidad basada en métricas y definición de un modelo de interconexión de componentes. La plataforma PicBit surge como respuesta a estas cuestiones. Consiste en una plataforma social de construcción de perfiles basada en estos elementos. Desde la perspectiva del usuario final se trata de una herramienta para crear perfiles y comunidades sociales, mientras que desde una perspectiva académica, la plataforma consiste en un entorno de pruebas o sandbox de componentes web. Para ello, será necesario implementar el extremo servidor de dicha plataforma, enfocado a la labor de explotación, por medio de la definición de una interfaz REST de operaciones y un sistema para la recolección de eventos de usuario en la plataforma. Gracias a esta plataforma se podrán discernir qué parámetros influyen positivamente en la experiencia de uso de un componente, así como descubrir el futuro potencial de este tipo de desarrollos.---ABSTRACT---The web evolves into a more interactive platform. From the actual version of the web, named as web 2.0, many paradigms and standards have arisen. One of those standards is web components, a set of concepts to define new HTML tags that covers a specific function inside a web page. It is necessary to measure the quality of this kind of software development, and the aim behind this approach is to determine if this new set of concepts would survive in the actual web paradigm. To achieve this, it is described a model to analyse components, in the terms of quality measure and interconnection model description. PicBit consists of a social platform to use web components. From the point of view of the final user, this platform is a tool to create social profiles using components, whereas from the point of view of technicians, it consists of a sandbox of web components. Thanks to this platform, we will be able to discover those parameters that have a positive effect in the user experience and to discover the potential of this new set of standards into the web 2.0.

online donde el contenido es creado por los propios usuarios mediante el uso de las tecnologías de la web 2.0, que facilitan la edición, la publicación y el intercambio de información, de tal manera que los social media están democratizando las comunicaciones. Según datos publicados por eMarketer, casi el 25% del total de la inversión publicitaria mundial para el 2014 estará dirigida a medios digitales. Los medios de comunicación tradicionales están sumidos desde algún tiempo en una profunda crisis. En los comienzos de Internet, los protagonistas de este sector han creído en la red como un medio de publicación de contenidos en una única dirección, esto es la web 1.0, personas conectándose a páginas web. El típico lector de revista y seminario se ha convertido en un nuevo consumidor con necesidades muy distintas. El lector de un medio tradicional se encuentra con contenido cerrado, sin posibilidad de ser filtrado, que busca dirigir su opinión. Con el método tradicional no es posible ni personalizar el contenido ni la experiencia de uso. De ahí el nacimiento de la web 2.0, personas conectándose a personas (redes sociales). En un futuro cercano, van a triunfar las empresas, sectores y marcas que sepan adaptarse a la llegada de los social media, y que además de desarrollar su línea de negocio habitual, se conviertan en plataformas para la conversación y la construcción de contenidos en colaboración. En este proyecto voy a desarrollar el caso particular de una empresa de telecomunicaciones con una estrategia que use los social media como plataforma de atención al cliente, y para interaccionar también con su almacén en DHL. Los servicios añadidos que dicha empresa de telecomunicaciones ofrece a sus seguidores, clientes externos e internos se pueden agrupar en las siguientes funcionalidades:  Hacer un volcado del sistema de gestión de incidencias de una empresa de telecomunicaciones en las redes sociales, a través de mensajes privados. Dichos mensajes privados se enviarán a las páginas de Facebook y Twitter de los clientes.  Seguimiento por parte del cliente de puestas en marcha de los nuevos servicios a través de mensajes privados en Facebook y Twitter. Mediante este servicio el cliente podrá comprobar a través de las redes sociales el estado de su pedido e intercambiar información de utilidad con la empresa.  Desarrollar a través de las redes sociales una herramienta de marketing para interaccionar con los clientes y posibles seguidores. A través de los canales de los social media se proporciona a los seguidores información de valor sobre novedades del mercado de las telecomunicaciones, soporte técnico, dudas, consejos sobre implementaciones técnicas, equipos de telecomunicaciones,.etc.Es decir, crear una plataforma de conversación entre usuarios, que aporte a los seguidores conocimientos y soluciones útiles para la problemática de sus negocios.  Usar Facebook como base de datos y medio de comunicación entre nuestra empresa de telecomunicaciones y el almacén externalizado en DHL. Supongo que la primera pregunta que debo responder sería, ¿por qué un cliente de una empresa de telecomunicaciones estaría interesado en seguir a su proveedor a través de redes sociales? Facebook tiene en 2014 1,28 billones de usuarios activos. Twitter, la cuarta plataforma social por número de usuarios tras Facebook, alcanzó los 255 millones de usuarios en los primeros meses de 2014. La segunda red social en número de seguidores es Youtube, con un billón de usuarios. El 61,5% de los usuarios de Facebook visita la red todos los días. Los twitteros envían 110 millones tweets por día, tienen fama de muy activos, especialmente por la mañana. En 60 días, se sube más contenido de vídeo a YouTube que el producido por las tres principales cadenas de televisión estadounidense durante 60 años. Como conclusión, las redes sociales están ganando cada día más terreno, es un entorno de comunicación bidireccional en auge cada vez más extendido, por lo cual los usuarios no tienen que dedicar tiempo extra a conocer la herramienta de atención al cliente de su empresa, al usar ésta un canal fácil, conocido, rápido, versátil y gratuito como son las redes sociales. ABSTRACT. Social media are platforms of online communication where content is created by users themselves using technologies of web 2.0, which facilitate the editing, publication and the exchange of information, so that the social media are democratizing communications. According to data published by eMarketer, nearly 25% of the total global ad spend for 2014 will target digital media. The traditional media are trapped for some time in deep crisis. In the early days of the internet, the players of the sector have believed in the network as a means of publishing content in a single direction, this is the web 1.0, connecting people to websites. The typical magazine reader has become a new consumer with very different needs. Traditional medium readers encounter a closed content, unable to be filtered, which seeks handle their opinion. The traditional method doesn’t allow to customize the content and user experience. Hence the birth of Web 2.0, connecting people to people. In the near future, will succeed companies, sectors and brands who can adapt to the advent of social media, and further to develop their line of business as usual, become platforms for conversation and building collaborative content. In this project I will develop the particular case of a telecommunications company with a strategy to use social media as a platform for Customer Service, and also to interact with DHL warehouse. The additional services that the company offers telecommunications followers, external and internal customers can be grouped into the following functionality:  Make a dump of the incident management system of a telecommunications company in social networks through private messages. These private messages are sent Facebook and Twitter clients.  Monitoring by the client launched new services through private messages on Facebook and Twitter. Through this service, customers can check through the social networks of your order status and share useful information with the company.  Develop through social media as a marketing tool to interact with customers and potential followers.Our telco will provide to followers through social media channels valuable information on market developments in telecommunications, technical support, questions, advice on technical implementations, telecommunications equipment,etc. Then we create a platform for discussion between users, to provide followers useful knowledge and solutions to their business problems.  Use Facebook as a database and means of communication between our telco and outsourced telecommunications in DHL warehouse. I guess the first question that must be answered is why a customer of a telecommunications company would be interested in following your provider via social networks. Facebook has 1.28 billion active users in 2014. Twitter, the fourth social platform for many users after Facebook reached 255 million users in the first months of 2014. The second social network on number of followers is YouTube, with a billion users. 61.5% of Facebook users visit the network every day. The twitter users send 110 million tweets per day, have a reputation for very active, especially in the morning. In 60 days, it is produced more video content to YouTube by the three major US television for 60 years. In conclusion, social networks are gaining more ground every day. It is an environment of two-way communication on the rise, so users do not have to spend extra time to learn the tool of Customer Care telco, by using this easy, known, fast, versatile and free channels as are social networks.
