En este artículo, se dan a conocer los hallazgos de este tipo, procedentes del museo provincial de Ciudad Real. La importancia de este lote de piezas, radica en el desconocimiento actual sobre estas producciones en el área castellano-manchega

Design and validation of novel methods for long-term road traffic forecasting

132 p.Road traffic management is a critical aspect for the design and planning of complex urban transport networks for which vehicle flow forecasting is an essential component. As a testimony of its paramount relevance in transport planning and logistics, thousands of scientific research works have covered the traffic forecasting topic during the last 50 years. In the beginning most approaches relied on autoregressive models and other analysis methods suited for time series data. During the last two decades, the development of new technology, platforms and techniques for massive data processing under the Big Data umbrella, the availability of data from multiple sources fostered by the Open Data philosophy and an ever-growing need of decision makers for accurate traffic predictions have shifted the spotlight to data-driven procedures. Even in this convenient context, with abundance of open data to experiment and advanced techniques to exploit them, most predictive models reported in literature aim for shortterm forecasts, and their performance degrades when the prediction horizon is increased. Long-termforecasting strategies are more scarce, and commonly based on the detection and assignment to patterns. These approaches can perform reasonably well unless an unexpected event provokes non predictable changes, or if the allocation to a pattern is inaccurate.The main core of the work in this Thesis has revolved around datadriven traffic forecasting, ultimately pursuing long-term forecasts. This has broadly entailed a deep analysis and understanding of the state of the art, and dealing with incompleteness of data, among other lesser issues. Besides, the second part of this dissertation presents an application outlook of the developed techniques, providing methods and unexpected insights of the local impact of traffic in pollution. The obtained results reveal that the impact of vehicular emissions on the pollution levels is overshadowe

The behaviour and use of space of the domestic fowl in alternative meat and egg production systems

164 p.Alternative poultry production is characterized by a large space availability provided to the birds as compared to intensive systems. A better space availability increased the behavioural and movement opportunities and, therefore, alternative poultry production is commonly associated with high animal welfare. However, in practice, it is commonly found that birds do not use the available space in a homogeneous way, and that the use of the outdoor area is lower than expected. In addition, increased freedom of movements and behavioural opportunities may raise the incidence of problematic behaviours such as aggressive interactions. Increasing the complexity of the environment (environmental enrichment) has been proposed to manage uneven spatial distribution and social interactions, but only in few instances implementation has been conducted under commercial conditions. The focus of this work was to investigate the way that egg and meat producing domestic fowl use the available space in alternative commercial production systems and their relation to behaviour and welfare indicators. The first study aimed at determining the use of space patterns in free-range laying hens, analysing their association with welfare outcomes at an individual level. To this aim three flocks located at three free-range farms were studied from 20-69 weeks of age. Behavioural and spatial data were collected over 150 individually tagged hens/farm. In a second study, using video recordings, the behaviour and the inter-individual distances of laying hens prior to an agonistic interaction were analysed to determine the causal factors triggering the encounter. The third and fourth studies investigated the impact of increasing environmental complexity by providing panels and perches in four commercial free-range slow-growing meat chicken farms. In each of the three houses (with panels, perches or controls), within each farm 50 birds were tagged for individual identification and their location and behaviour registered during a production cycle (82 days). The main findings of these studies indicate that on average 32.58% of the free-range laying hens used the outdoor area regularly, while 49.45% were never observed using it. The hens¿ previous experience was identified as a primary factor affecting to the frequency of use of the outdoor area in successive age periods. The frequency of use of the outdoor area and total walked distance inside correlated with welfare indicators such as plumage condition and pododermatitis, respectively. On the other hand, the study on the inter-individual distances and behaviour prior to an aggressive encounter suggest that aggression in laying hens does not depend on the invasion of the critical distance per se, but would greatly depend on the activity level and directionality of the individuals which would be perceived as a threat by the aggressor. In free-range slow-growing meat chickens, a higher frequency of locomotive behaviours in the central area within the panel treatment was observed in comparison to controls. The size of the 50 and 100% core areas increased with age but no effect of increasing environmental complexity was detected. The effect of panels and perches in this study had a more noticeable effect on the use of the space patterns inside the house and very limited impact on their behaviour, probably because the number of devices used was limited. In this study, the environmental complexity interventions did not appeared to have a direct impact on welfare indicators assessed

Vajilla metálica de época romana en los museos de Ciudad Real, Jaén y Linares

La catalogación, el estudio y la publicación de los fondos museísticos que contengan materiales adscritos a la familia de los objetos metálicos, es una tarea necesaria que se está llevando a cabo desde tiempos relativamente recientes. Uniéndonos a esta dinámica, queremos dar a conocer una serie de piezas, depositadas en los museos de Jaén, Linares y Ciudad Real. Los rasgos comunes que las definen están orientados en torno a dos puntos básicos. El primero, sería su pertenencia a un área geográfica homogénea, la antigua Oretania, región de límites algo imprecisos, pero que en líneas generales se enmarca en las actuales provincias de Ciudad Real y Jaén. Y, por último, todos los ejemplares que presentamos pertenecen a la categoría de la vajilla metálica

From the Queue to the Quality of Service Policy: A Middleware Implementation

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-02481-8_61Quality of service policies in communications is one of the current trends in distributed systems based on middleware technology. To implement the QoS policies it is necessary to define some common parameters. The aim of the QoS policies is to optimize the user defined QoS parameters. This article describes how to obtain the common QoS parameters using message queues for the communications and control components of communication. The paper introduces the Queue-based Quality of Service Cycle concept for each middleware component. The QoS parameters are obtained directly from the queue parameters, and Quality of Service Policies controls directly the message queues to obtain the user-defined parameters values.The middleware architecture described in this article is a part of the coordinated project SIDIRELI: Distributed Systems with Limited Resources.

Las armaduras segmentadas (loricae segmentatae) en los yacimientos romanos de la provincia de León: un estudio de conjunto

We analyze the unpublished discoveries of loricae segmentatae from León province. In that territory, all the recognizable categories are attested. Sites from León offer the most advanced late chronology in the whole Empire, regarding armours to “Corbridge” and “Newstead” types, fact corroborated in diverse excavations. It will be necessary to consider when we date these loricae segmentatae in the future.Se estudian los abundantes restos inéditos de loricae segmentatae procedentes de la provincia de León, donde se documentan todas las variantes de estas piezas conocidas hasta el momento. Los yacimientos leoneses han proporcionado la cronología final más avanzada de todo el Imperio respecto a las armaduras “Corbridge” y a las corazas “Newstead”, dato corroborado en diversas excavaciones y que deberá ser tenido en cuenta a la hora de fechar estas categorías en el futuro
