Cultural heritage is a complex and diverse concept, which brings together a wide domain of information. Resources linked to a cultural heritage site may consist of physical artefacts, books, works of art, pictures, historical maps, aerial photographs, archaeological surveys and 3D models. Moreover, all these resources are listed and described by a set of a variety of metadata specifications that allow their online search and consultation on the most basic characteristics of them. Some examples include Norma ISO 19115, Dublin Core, AAT, CDWA, CCO, DACS, MARC, MoReq, MODS, MuseumDat, TGN, SPECTRUM, VRA Core and Z39.50. Gateways are in place to fit in these metadata standards into those used in a SDI (ISO 19115 or INSPIRE), but substantial work still remains to be done for the complete incorporation of cultural heritage information. Therefore, the aim of this paper is to demonstrate how the complexity of cultural heritage resources can be dealt with by a visual exploration of their metadata within a 3D collaborative environment. The 3D collaborative environments are promising tools that represent the new frontier of our capacity of learning, understanding, communicating and transmitting culture.

Nowadays, many researches focus their efforts in studies and applications on the Learning area. However, there is a lack of a reference system that permits to know the positioning and the existing links between Learning and Information Technologies. This paper proposes a Cartography where explains the relationships between the elements that compose the Learning Theories and Information Technologies, considering the own features of the learner and the Information Technologies Properties. This intersection will allow us to know what Information Technologies Properties promote Learning Futures.

The problem is general: modern architects and engineers are trying to understand historic structures using the wrong theoretical frame, the classic (elastic) thery of structures developed in the 19th Century for iron and stell, and in the 20th century for reinforced concrete, disguised with "modern" computer packages, mainly FEM, but also others. Masonry is an essentially different material, and the structural equations must be adapted accordingly. It is not a matter of "taste" or "opinion", and the consequences are before us. Since, say 1920s, historic monuments have suffered the aggression of generations of archietcts and engineers, trying to transform masonry in reinfored concrete or steel. The damage to the monuments and the expense has been, and is, enormous. However, as we have an adequate theory (modern limit analysis of masonry structures, Heyman 1966) which encompasses the "old theory" used successfully by the 18th and 19th Century practical engineers (from Perronet to Sejourné), it is a matter of "Ethics" not to use the wrong approach. It is also "contra natura" to modify the material masonry with indiscriminate injections, stitchings, etc. It is insane to consider, suddenly, that buildings which are Centuries or milennia old, are suddenly in danger of collapse. Maintenance is necessary but not the actual destruction of the constructive essence of the monument. A cocktail of "ignorance, fear and greed" is acting under the best of intentions.

Presenting relevant information via web-based user friendly interfac- es makes the information more accessible to the general public. This is especial- ly useful for sensor networks that monitor natural environments. Adequately communicating this type of information helps increase awareness about the limited availability of natural resources and promotes their better use with sus- tainable practices. In this paper, I suggest an approach to communicating this information to wide audiences based on simulating data journalism using artifi- cial intelligence techniques. I analyze this approach by describing a pioneer knowledge-based system called VSAIH, which looks for news in hydrological data from a national sensor network in Spain and creates news stories that gen- eral users can understand. VSAIH integrates artificial intelligence techniques, including a model-based data analyzer and a presentation planner. In the paper, I also describe characteristics of the hydrological national sensor network and the technical solutions applied by VSAIH to simulate data journalism.

The Linked Data initiative offers a straight method to publish structured data in the World Wide Web and link it to other data, resulting in a world wide network of semantically codified data known as the Linked Open Data cloud. The size of the Linked Open Data cloud, i.e. the amount of data published using Linked Data principles, is growing exponentially, including life sciences data. However, key information for biological research is still missing in the Linked Open Data cloud. For example, the relation between orthologs genes and genetic diseases is absent, even though such information can be used for hypothesis generation regarding human diseases. The OGOLOD system, an extension of the OGO Knowledge Base, publishes orthologs/diseases information using Linked Data. This gives the scientists the ability to query the structured information in connection with other Linked Data and to discover new information related to orthologs and human diseases in the cloud.

We present two approaches to cluster dialogue-based information obtained by the speech understanding module and the dialogue manager of a spoken dialogue system. The purpose is to estimate a language model related to each cluster, and use them to dynamically modify the model of the speech recognizer at each dialogue turn. In the first approach we build the cluster tree using local decisions based on a Maximum Normalized Mutual Information criterion. In the second one we take global decisions, based on the optimization of the global perplexity of the combination of the cluster-related LMs. Our experiments show a relative reduction of the word error rate of 15.17%, which helps to improve the performance of the understanding and the dialogue manager modules.

In multi-attribute utility theory, it is often not easy to elicit precise values for the scaling weights representing the relative importance of criteria. A very widespread approach is to gather incomplete information. A recent approach for dealing with such situations is to use information about each alternative?s intensity of dominance, known as dominance measuring methods. Different dominancemeasuring methods have been proposed, and simulation studies have been carried out to compare these methods with each other and with other approaches but only when ordinal information about weights is available. In this paper, we useMonte Carlo simulation techniques to analyse the performance of and adapt such methods to deal with weight intervals, weights fitting independent normal probability distributions orweights represented by fuzzy numbers.Moreover, dominance measuringmethod performance is also compared with a widely used methodology dealing with incomplete information on weights, the stochastic multicriteria acceptability analysis (SMAA). SMAA is based on exploring the weight space to describe the evaluations that would make each alternative the preferred one.

Millennium Development Goals point out the necessity of actively promoting maternal-child health care status, especially in underserved areas. This article details the development actions carried out between 2008 and 2011 in some rural communities of Nicaragua with the aim to provide a low-cost tele-health communication service. The service is managed by the health care center of Cusmapa, which leads the program and maintains a communication link between its health staff and the health brigades of 26 distant communities. Local agents can use the system to report urgent maternal-child health care episodes to be assessed through WiMAX-WiFi voice and data communications attended by two physicians and six nurses located at the health care center. The health and nutritional status of the maternal-child population can be monitored to prevent diseases, subnutrition, and deaths. The action approach assumes the fundamentals of appropriate technology and looks for community- based, sustainable, replicable, and scalable solutions to ensure future deployments according to the strategies of the United Nations.

This paper describes an automatic-dependent surveillance-broadcast (ADS-B) implementation for air-to-air and ground-based experimental surveillance within a prototype of a fully automated air traffic management (ATM) system, under a trajectory-based-operations paradigm. The system is built using an air-inclusive implementation of system wide information management (SWIM). This work describes the relations between airborne and ground surveillance (SURGND), the prototype surveillance systems, and their algorithms. System's performance is analyzed with simulated and real data. Results show that the proposed ADS-B implementation can fulfill the most demanding surveillance accuracy requirements.

The lack of useful information has become a major obstacle that hinders the participation of the members of the community in the development process because they can not accurately perceive how their individual and/or collective action can influence their environment, and because of the lack of elements that support the decision-making processes. This article addresses these issues from the work carried out by the Association Instituto de Desarrollo Comunitario de Cuenca (IDC Cuenca) in the rural areas of this province of Spain for 25 years. The results show how the application of methodologies for the transmission of information tailored to each group of recipients in some aspects, enhances the participation of individuals.

Software Configuration Management (SCM) techniques have been considered the entry point to rigorous software engineering, where multiple organizations cooperate in a decentralized mode to save resources, ensure the quality of the diversity of software products, and manage corporate information to get a better return of investment. The incessant trend of Global Software Development (GSD) and the complexity of implementing a correct SCM solution grow not only because of the changing circumstances, but also because of the interactions and the forces related to GSD activities. This paper addresses the role SCM plays in the development of commercial products and systems, and introduces a SCM reference model to describe the relationships between the different technical, organizational, and product concerns any software development company should support in the global market.

Aiming to address requirements concerning integration of services in the context of ?big data?, this paper presents an innovative approach that (i) ensures a flexible, adaptable and scalable information and computation infrastructure, and (ii) exploits the competences of stakeholders and information workers to meaningfully confront information management issues such as information characterization, classification and interpretation, thus incorporating the underlying collective intelligence. Our approach pays much attention to the issues of usability and ease-of-use, not requiring any particular programming expertise from the end users. We report on a series of technical issues concerning the desired flexibility of the proposed integration framework and we provide related recommendations to developers of such solutions. Evaluation results are also discussed.

One of the main problems in urban areas is the steady growth in car ownership and traffic levels. Therefore, the challenge of sustainability is focused on a shift of the demand for mobility from cars to collective means of transport. For this end, buses are a key element of the public transport systems. In this respect Real Time Passenger Information (RTPI) systems help citizens change their travel behaviour towards more sustainable transport modes. This paper provides an assessment methodology which evaluates how RTPI systems improve the quality of bus services in two European cities, Madrid and Bremerhaven. In the case of Madrid, bus punctuality has increased by 3%. Regarding the travellers perception, Madrid raised its quality of service by 6% while Bremerhaven increased by 13%. On the other hand, the users ́ perception of Public Transport (PT) image increased by 14%.

Fundamento de la tesis: Al comienzo del siglo XX, el interés por el turismo unido a la necesidad de restaurar un abundante patrimonio histórico, posibilitó en España que los poderes públicos se embarcaran en una singular experiencia: la creación de una infraestructura hotelera a partir de la rehabilitación de edificios históricos. La preservación, mantenimiento e incluso rentabilidad de una gran parte del patrimonio español se haría efectiva a través de la innovadora fórmula patrimonio‐turismo, cuya máxima expresión se materializó en la Red de Paradores desde su fundación en la segunda década del siglo pasado hasta nuestros días. Sorprendentemente, este tema no ha sido todavía investigado en su vertiente arquitectónica pese a que España ha sido pionera y modelo en la cuestión de la hotelería pública. Este trabajo aborda el estudio del caso más significativo de todos los edificios de la red, en tanto que el patrimonio que ha servido de base a los fines hoteleros del Estado ha contado con un total de seis tipos arquitectónicos a lo largo de su historia, dentro de los cuales la arquitectura militar despunta con su mayoritaria presencia dentro del contexto de los edificios históricos de la red. El carácter arquetípico de los castillos y fortalezas, arraigado en el inconsciente colectivo, les hizo especialmente atractivos como alojamiento turístico al permitir evocar la remota época medieval, pese a ser el tipo arquitectónico más comprometido para la rehabilitación hotelera. El estudio de las intervenciones operadas en estos inmuebles se revela de forma clara como escaparate de los distintos criterios de intervención patrimonial que se han sucedido en el siglo XX, hasta enlazar con la perspectiva interdisciplinar actual. La tesis abarca en, primer lugar, diferentes aspectos generales relativos al promotor hotelero, la hotelería pública de ámbito nacional e internacional, y la caracterización de los inmuebles de la red estatal española, desde el punto de vista hotelero y arquitectónico, entendida esta última en sus tres escalas de influencia: la arquitectónica, la urbana o paisajística, y la del interiorismo. Se analiza en segundo término la arquitectura militar dentro del contexto de la Red de Paradores, desde la consideración de su transformación hotelera, para lo cual ha sido necesario realizar una clasificación propia, que abarca tanto edificios que respondieron a una estructura de cuartel, como castillos‐palacio, o fortalezas que habían servido a los fines de una orden religiosa militar, además de considerarse las intervenciones en recintos históricos de carácter militar, donde se hacía obligatorio construir de nueva planta. En tercer y último lugar, se analiza a lo largo de las distintas etapas del organismo turístico las rehabilitaciones realizadas en estas construcciones militares, a la vez que se tienen en cuenta las intervenciones en los restantes edificios históricos, para evitar la descontextualización. Este recorrido comienza con la promoción de los dos primeros paradores a cargo del Comisario Regio, el marqués de la Vega‐Inclán, que sirvieron para sentar las bases de los conceptos e ideas que habrían de desarrollarse en las siguientes décadas. Posteriormente, se desarrolló y tomó forma la red con el Patronato Nacional del Turismo, en la que las primeras intervenciones en tipos militares se tradujeron en reformas interiores de locales. La etapa clave de la red, y en particular de la arquitectura militar, tuvo lugar con el Ministerio de Información y Turismo, marcada por la “repristinación” de monumentos, tras un período preparatorio con la Dirección General del Turismo en el que lo militar había quedado de telón de fondo de otros tipos arquitectónicos. Tras el auge del Ministerio llegó el período de decadencia en el que los castillos y fortalezas desaparecieron de los intereses de las Secretarias de Turismo, hasta llegar a las inauguraciones de los novedosos establecimientos del siglo XXI y el resurgimiento del tipo militar con el parador de Lorca. Metodología empleada: Este trabajo de investigación se ha servido fundamentalmente de documentación inédita, procedente de diversos archivos, además de una muy extensa toma de datos in situ. Dentro del patrimonio analizado, los inmuebles que responden al tipo arquitectónico militar se han dividido en tres grandes grupos: inmuebles rehabilitados que entraron en funcionamiento en la red, inmuebles en proceso de transformación hotelera, e inmuebles que fueron adquiridos con fines hoteleros pero que no llegaron a rehabilitarse. Para cada uno de ellos ha sido necesario determinar en qué estado llegaron a manos de la Administración Turística, cuál fue el mecanismo a través del cual se adquirieron, en qué consistió su primera rehabilitación hotelera, y cuáles fueron las ampliaciones o reformas más significativas que se realizaron posteriormente. Estos datos se han sintetizado en fichas y se han extraído conclusiones al comparar cada unidad con el conjunto. Simultáneamente se introdujeron dos factores externos: la historia del turismo que permitió hacer una ordenación cronológica de los inmuebles según etapas, y la historia de la teoría y práctica de la intervención patrimonial en España que permitió comparar los criterios patrimoniales de la Administración competente respecto de las intervenciones de la Administración Turística, cuyo contacto se haría obligatorio a partir del Decreto, de 22 de abril de 1949, que dejaba bajo la tutela del Estado a todos los castillos y fortalezas. Aportación de la tesis: Con carácter general, la tesis centra una ordenación y sistematización completa del patrimonio inmobiliario de la red, desde el punto de vista de los tipos hoteleros y arquitectónicos, además de poner por primera vez en conexión distintos modelos de hotelería pública, para constituirse en el sustrato de futuras investigaciones. El estudio realizado se ha hecho extensivo a las distintas escalas que inciden de forma interconectada en la implantación de un parador: la arquitectónica, la urbana y la del interiorismo, hasta ahora referenciado desde la exclusiva visión arquitectónica. Se han definido las etapas de la historia de la red, no ya sólo a partir del hilo conductor de la cadena sucesiva de organismos turísticos, sino que por primera vez se hace en razón de la evolución que sufren las intervenciones patrimoniales a lo largo del tiempo, a la vez que se entra en conexión con la teoría y praxis de la restauración monumental. Con carácter particular, la arquitectura militar dentro del contexto de los paradores se destaca en el período del Ministerio, en el que se experimentaron todas las posibilidades que presentaba su rehabilitación. En este sentido se ha puesto de manifiesto en este trabajo un tipo híbrido de parador, a caballo entre la rehabilitación y la edificación de nueva planta, las dos formas básicas de establecimiento creadas en la Comisaría Regia, al que se ha denominado edificación de nueva planta en recinto histórico militar. Esta nueva caracterización se ha valorado como la forma más eficiente de implantar paradores, cuyas pautas arquitectónicas abarcaron un abanico de posibilidades: imitación de modelos arquitectónicos históricos con utilización de elementos patrimoniales prestados que dieran el valor de la historia, utilización de un lenguaje moderno, o la inspiración en la arquitectura vernácula. La amalgama de elementos, estilos e intervenciones sucesivas de ampliación fue la característica común tanto para la implantación de un parador en un edificio como en un recinto amurallado. La arquitectura militar transformada en establecimiento hotelero evidencia la vocación escenográfica de las intervenciones patrimoniales, secundada por el interiorismo, además de su aportación a la arquitectura hotelera en lo referente al confort, organización y funcionamiento de sus instalaciones. La tesis ahonda en los diversos aspectos de la rehabilitación hotelera apuntados de forma parcial por algunos autores, y pone de manifiesto la “ambientación medieval” operada en la arquitectura militar, que llegó a tener su máxima expresión con el criterio de la “unidad de estilo” del Ministerio de Información y Turismo. La rehabilitación hotelera dentro del contexto de la Red de Paradores, queda caracterizada en la tesis en relación a intervenciones en construcciones militares, cuya sistematización puede ser extrapolable a otros tipos arquitectónicos o cadenas hoteleras de titularidad pública, a partir del estudio que se ha avanzado en este trabajo. Thesis basis: At the beginning of the 20th century the interest in tourism added to the plentiful heritage in Spain enabled the authorities to embark on a singular experience: the creation of a hotel infrastructure from the restoration of historic buildings. Preservation, maintenance, and even profitability of a large part of the Spanish heritage would be effective through the innovative formula heritage-tourism. Its greatest expression materialized in the Paradores Network since its foundation in last century’s second decade to the present day. Surprisingly, this subject has not yet been investigated in its architectural aspect, even though Spain has been a pioneer and a model in the matter of public hotel business. This project tackles the study of the most significative case of all the network’s buildings, since the heritage which has served throughout history as a base for the State hotel purposes has altogether six architectural types, among which military architecture stands out with its majority presence in the context of the historical buildings of the network. The archetypal character of castles and fortresses, ingrained in the collective subconscious, made them specially attractive for tourist accommodation, as it allowed the evocation of far medieval times, despite being the most awkward architectural type for hotel restoration. The study of the interventions in these buildings clearly reveals itself as a showcase of the different criteria of heritage intervention along the 20th century, connecting to the present interdisciplinary perspective. Firstly, the thesis covers different general aspects regarding the hotel developer, the domestic and international public hotel business, and the description of the Spanish state network buildings from a hotel business and an architectural point of view, the latter from its three influence scales: architectural, urban or landscape, and interior design. Secondly, the transformation of the military architecture in the Paradores Network into hotels is analyzed. For that purpose it was necessary to create a specific classification, which included barrack-structured buildings, castle-palaces, or fortresses which served the purposes of military-religious orders. The interventions in those military historical places where new building became compulsory were also taken into consideration. Thirdly and lastly, the thesis analyses the restorations in these military constructions through the different stages of the tourist organization. In order to avoid decontextualization, interventions in other historical buildings were also considered. This route begins with the promotion of the two first Paradores by the Royal Commissioner, the marquis of Vega-Inclán, which paved the way for the concepts and ideas that were developed in the following decades. Subsequently, the network was developed and took shape with the National Tourism Board. The first interventions on military types were inside refurbishments. The Network’s key period, and in particular of its military architecture, took place with the Ministry of Information and Tourism, a time marked by the “restoration to its original state” of monuments. This stage arrived after a preparatory period with the State Tourist Office, when the military type was left as a backdrop for other architectural types. After the Ministry’s boom arrived a decline, in which castles and fortresses disappeared from the Tourist Department’s interests up to the opening of the 21st century new establishments and the resurgence of the military type with Lorca’s Parador. Methodology: The present research project has mainly used unpublished documentation from several archives and has done an extensive in situ data-gathering. Within the heritage analyzed, military buildings have been divided into three main groups: restored buildings that began to operate in the network, those in process of hotel transformation, and those acquired for hotel purposes, but which did not become restored. In each case, it has been necessary to determine the condition in which they arrived to the Tourist Administration, the procedure by which they were acquired, what their first hotel restoration consisted of, and which their subsequent most significative enlargements and alterations were. These facts have been synthesized in cards, and conclusions were drawn by comparing each unit with the whole. Simultaneously, two external factors were introduced: the history of tourism, that allowed establishing a chronological order according to different periods, and the history of Spanish heritage intervention’s theory and practice, that permitted to compare the heritage criteria from the competent Administration with those of the Tourist Administration’s interventions. Both Administrations came compulsorily into contact after the Decree of 22nd April 1949, by which all castles and fortresses became under the protection of the State. Thesis contribution: In general, the thesis focuses on a complete order and systematization of the network’s heritage buildings from the hotel and architectural types points of view, besides connecting for the first time different public hotel business models, becoming the substratum for future investigations. The study has included the different scales that impact interconnected on the establishment of a Parador: architectural, urban and interior design, only referenced to date from an architectural point of view. The Network’s history stages have been defined according to not only a consecutive series of tourist organizations, but also, and for the first time, to the evolution of heritage interventions over time, thus connecting with the theory and praxis of monumental restoration. In particular, within the Paradores, military architecture stands out in the Ministry’s period, in which all kind of restoration possibilities were explored. In this sense, the present project puts forth a hybrid type of Parador between restoration and new building, the two basic ways of establishment created in the Royal Commission, termed new building in military historic enclosure. This new characterization has been evaluated as the most efficient for establishing Paradores, whose architectonic guidelines include a wide range of possibilities: the imitation of historical architectonic models with use of borrowed heritage components that provide historical value, the use of modern language, or the inspiration in vernacular architecture. The amalgam of elements, styles and consecutive enlargement interventions was the common feature of the establishment of a Parador, both in a building or in a walled enclosure. The military architecture transformed into a hotel establishment gives proof of the scenographic vocation of heritage interventions, supported by interior design, as well as of its contribution to hotel architecture, related to its comfort, organization and the functioning of its facilities. The thesis delves into the diverse aspects of hotel restoration, partially pointed out by several authors, and puts forth the creation of a “medieval atmosphere” in military architecture, which came to its highest expression with the “unitary style” criteria of the Ministry of Information and Tourism. Hotel restoration within the context of the Paradores’ Network is defined in this thesis in relation to interventions in military constructions, whose systemization can be extrapolative to other architectural types or public hotel chains, based on the study which has been put forward in this project.
