This paper presents the first results of our most recent research on the Bilbao Stock Exchange (BSE) from its foundation in 1890 up to the Spanish CivilWar.We examine the origin of the Exchange and follow its evolution over the first half-century of existence. To this end we introduce some of the stock exchange indexes we have calculated for Bilbao and put them into comparative perspective with the existing series on general economic and industrial activity and the indexes for other Spanish exchanges for the period considered. These comparisons show Bilbao's evolution from a public debt-dominated market to an industrial exchange very much tied to regional development. Finally, we contrast the degree of financial market integration associated with the existing Spanish exchange indexes. Our analysis finds strong support for considering the BSE index as an industrial index and little evidence of capital market integration between the principal Spanish exchanges before the 1920s.

Direct numerical simulations of heat transfer in a fully-developed turbulent pipe flow with circumferentially-varying thermal boundary conditions are reported. Three cases have been considered for friction Reynolds number in the range 180–360 and Prandtl number in the range 0.7–4. The temperature statistics under these heating conditions are characterized. Eddy diffusivities and turbulent Prandtl numbers for radial and circumferential directions are evaluated and compared to the values predicted by simple models. It is found that the usual assumptions made in these models provide reasonable predictions far from the wall and that corrections to the models are needed near the wall.; O.F. and M.G.-V. were partially supported by Grant TRA2013-41103-P of the Spanish Ministry of Economy and Competitiveness.

The Data Mining Cloud Framework (DMCF) is an environment for designing and executing data analysis workflows in cloud platforms. Currently, DMCF relies on the default storage of the public cloud provider for any I/O related operation. This implies that the I/O performance of DMCF is limited by the performance of the default storage. In this work we propose the usage of the Hercules system within DMCF as an ad-hoc storage system for temporary data produced inside workflow-based applications. Hercules is a distributed in-memory storage system highly scalable and easy to deploy. The proposed solution takes advantage of the scalability capabilities of Hercules to avoid the bandwidth limits of the default storage. Early experimental results are presented in this paper, they show promising performance, particularly for write operations, compared to the performance obtained using the default storage services.; This work is partially supported by EU under the COST Program Action IC1305: Network for Sustainable Ultrascale Computing (NESUS). This work is partially supported by the grant TIN2013-41350-P, Scalable Data Management Techniques for High-End Computing Systems from the Spanish Ministry of Economy and Competitiveness.

Exploiting the use-dependent plasticity of our neuromuscular system, neuro-rehabilitation therapies are devised to help patients that suffer from injuries or diseases in this system, such as those caused by brain damage before or during birth or in the first years of life (e.g. due to cerebral palsy or obstetric brachial plexus palsy). These therapies take advantage of the fact that the motor activity alters the properties of our neurons and muscles, including the pattern of their connectivity, and thus their functionality. Hence, a sensor-motor treatment where the patient makes certain movements, will help her to (re)learn how to move the affected body parts. But this traditional rehabilitation processes come at a cost: therapies are usually repetitive and lengthy, reducing motivation and adherence to the treatment and thus limiting the benefits for the patients. This paper describes the motivation, experiences and current efforts towards the final development of THERAPIST, a socially interactive robot for neuro-rehabilitation assistance. Our starting hypothesis was that patients could get consistently engaged in a therapeutic non-physical interaction with a robot, facilitating the design of new therapies that should improve the patient recovery time and reduce the overall socio-economic costs. This hypothesis was validated by our initial experimental studies...

Data movement is becoming a key issue in terms of performance and energy consumption in high performance computing (HPC) systems, in general, and Exascale systems, in particular. A preliminary step to perform I/O optimization and face the Exascale challenges is to deepen our understanding of energy consumption across the I/O stacks. In this paper, we analyze the power draw of different I/O operations using a new fine-grained internal wattmeter while simultaneously collecting system metrics. Based on correlations between the recorded metrics and the instantaneous internal power consumption, our methodology identifies the significant metrics with respect to power consumption and decides which ones should contribute directly or in a derivative manner. This approach has the advantage of building I/O power models based on a previous set of identified utilization metrics. This technique will be validated using write operations on an Intel Xeon Nehalem server system, as writes exhibit interesting patterns and distinct power regimes.; The work presented in this paper has been partially supported by the EU Project FP7 318793 “EXA2GREEN” and partially supported by the EU under the COST Programme Action IC1305, “Network for Sustainable Ultrascale Computing (NESUS)” and by the grant TIN2013-41350-P...

Complex robotic tasks require the coordination of a considerable amount of skills. This is generally achieved generating and executing action plans that fulfill the preconditions of the given objective. These tasks can be highly dynamic, since the appearance of new objects or unexpected situations is a constant during the plan execution. In this context, robot control systems require the capability of managing a suitable world model (creating, removing or retyping dynamically objects as a result of the plan execution), and the capability of monitoring and replanning when unexpected situations are detected. In this paper we introduce a general-purpose architecture for autonomous mobile robots providing these features. The architecture allows to generate planning applications since it integrates planning, re-planning, monitoring and learning capabilities, and, at the same time, manages a consistent graph-like world model. Finally, we present some preliminary results of the deployment of such architecture in an advertisement promoting robot domain.; This paper has been partially supported by the Spanish Ministerio de Economía y Competitividad TIN2012-TIN2012-38079 and FEDER funds, and by the Innterconecta Programme 2011 project ITC-20111030 ADAPTA.; This paper at: 15th Workshop of Physical Agent. at took place...

This paper examines the effect of violent crime on the prevalence of early motherhood in Colombia. To instrument for the predominance of violent crime I use geographical and temporal variation in drug trafficking networks. My results suggest that one standard deviation increase in the homicide rate induces a 2.55 percentage points increase in the probability of early motherhood

Artificial vision systems can not process all the information that they receive from the world in real time because it is highly expensive and inefficient in terms of computational cost. However, inspired by biological perception systems, it is possible to develop an artificial attention model able to select only the relevant part of the scene, as human vision does. From the Automated Planning point of view, a relevant area can be seen as an area where the objects involved in the execution of a plan are located. Thus, the planning system should guide the attention model to track relevant objects. But, at the same time, the perceived objects may constrain or provide new information that could suggest the modification of a current plan. Therefore, a plan that is being executed should be adapted or recomputed taking into account actual information perceived from the world. In this work, we introduce an architecture that creates a symbiosis between the planning and the attention modules of a robotic system, linking visual features with high level behaviours. The architecture is based on the interaction of an oversubscription planner, that produces plans constrained by the information perceived from the vision system, and an object-based attention system...

Bootstrap procedures are useful in GARCH models to obtain forecast densities for returns and volatilities.In this paper, we analyze the effect of outliers on the finite sample properties of these densities when they are based on standard maximum likelihood and robust procedures. We show that when the former procedure is implemented, the bootstrap densities are badly affected by the presence of outliers. However,the robust estimator based on variance targeting with an adequate modification of the volatility filter has the best performance when compared with alternative robust procedures. The results are illustrated withboth simulated and real data; The second author also acknowledges financial support from CAPES while the third author is grateful for financial support from the Spanish Ministry of Education and Science, research project ECO2012-32401

A rehabilitation therapy usually derives from general goals set by the medical expert, who requests the patient to attend sessions during a certain time period in order to help him regaining mobility, strength and/or flexibility. The therapist must transform these general goals manually into a set of exercises distributed over different rehabilitation sessions that compose the complete therapy plan, taking into account the patient clinical conditions and a predetermined session and therapytime. This becomes a hard task and might lead to rigid schedules which not always accomplish the desired achievement level of therapeutic objectives established by the physician and could have a negative impact on the patients' engagement in the therapy. Classical and Hierarchical Task Network planning approaches have been used in this paper to compare the modellingand results of both domain formulations for the automatic generation of therapy plans for patients suffering obstetric rachial plexus palsy, in response to a given set of therapeutic objectives.; This work has been partially granted by the Spanish Ministerio de Economía y Competitividad (MINECO) funds under coordinated project no.

Mobile broadband services are growing rapidly in the last few years due to the deployment of Long Term Evolution (LTE) cellular networks. Among them, multicast services can be provided using Evolved Multimedia Broadcast and Multicast Service (eMBMS), available with 3rd Generation Partnership Project (3GPP) release 9, which can deliver broadcast/multicast content using a single-frequency network mode. This means sending the same multimedia content to a mass audience within a specific area. The utilization of the Conventional Multicast Scheme (CMS) approach for multicast resource allocation presents intrinsic inefficiencies, because of the different channel conditions of the users which demand the service. This paper proposes a Joint Multicast Subgrouping and Unicast Transmissions (JMSUT) strategy for resource allocation, which consists of the use of the multicast and the unicast transmissions, by means of the subframes reserved by the LTE standard for each purpose, to deliver a multicast service. The goal of the JMSUT algorithm is to maximize the service throughput whereas it guarantees the fulfillment of the Quality of Service (QoS) requirements of every user. This paper solves the former maximization problem of the joint resource allocation; on the one hand...

El presente artículo estudia la confluencia del valor de culto y del valor cultural en inmuebles catalogados como bienes de interés cultural en propiedad y posesión de la Iglesia Católica. Tras un análisis de la evolución hasta el significado presente del valor cultural y de sus componentes históricas y artísticas así como del valor de culto, desde la formación de un patrimonio asignado al mismo a las consideraciones actuales, se reflexiona sobre la convivencia entre ambos concepto de valor cuando coinciden en la misma realidad construida. El examen del marco jurídico de la regulación en el derecho canónico, en el derecho comparado y en el derecho español y la investigación en torno a las cualidades intrínsecas de la arquitectura sirven de base para aportar soluciones a los posibles conflictos.; This article examines the convergence of a worship value and a cultural value in buildings listed as heritage which are in ownership and possession of the Catholic Church. After an analysis of the evolution towards the current meaning of cultural value and its historical and artistic components as well as the value of worship, from the formation of heritage specifically for cultural means to modern-day considerations, there follows a reflection about the coexistence of both when they appear in the same constructed reality.

This article investigates the rise of the middle class in Brazil between the mid-nineteenth and mid-twentieth centuries and its connection with inequality. To this purpose Brazil's income distribution is explored from two dimensions: inequality and polarisation. A new middle class index (MCI), based on polarisation methods, is used to assess the evolution of the middle class in terms of both income and status. Results suggest that during the nineteenth century low income levels prevented the achievement of high inequality values and the emergence of a middle class. Then in the early twentieth century Brazil experienced a process of economic growth accompanied by increasing inequality in a Kuznetsian sense in which the middle class arose. Yet, despite rapid economic growth during the following decades, the continued increase of inequality, especially between 1930 and 1950, impeded the consolidation of the middle class and the reduction of poverty.; This study has been developed with the financial support of Universidad Carlos III de Madrid through the PIF fellowship.

The cutting tool geometry is known to be an influential factor on damage induced during drilling of composite materials. Conversely, the geometry of the tool is affected under multiple drilling cycles due to highly abrasive nature of fibers. Building on earlier reports, the aim of this work is to create a better understanding of cutting parameters on the quality of drilled woven carbon fiber reinforced polymer (CFRP) laminates, given different tool wear conditions. Namely, a full factorial design of experiments has been conducted to quantify the significance of each process parameter (cutting velocity, feed rate and tool point angle), as well as their interactions, on the generation of entry- and exist- delaminations as well as the thrust force for different tool types. Finally, using a response surface methodology, a multi-objective optimization strategy has been presented to select optimum ranges of design parameters that can minimize the aforementioned output variables collectively. Such knowledge may be useful to explore further improvements toward defect-free drilling of woven CFRP composites.; The authors acknowledge the financial support for this work from the Ministry of Economy and Competitiveness of Spain under the project DPI2011-25999 and FPI subprogram with the reference BES-2012-055162...
