    \cf1\f1 This paper analyzes how State aid affects and distorts competition and trade within and across jurisdictions. We identify the circumstances in which state aid is likely to involve the largest distortions. In the context of the paper distortion of competition" is interpreted as the effect on rivals\f2\rquote\f1 profits. We consider three types of state intervention, namely subsidies which affect marginal cost, entry and quality and analyse whether particular market characteristics are robust indicators of the magnitude of the distortions. We obtain the following results: (i) it appears that concentration is a fairly robust indicator; (ii) A high degree of substitution across differentiated products is not a robust indicator of the magnitude of the distortions. Its effect depends on the type of state intervention; (iii) The substitution among domestic products may have opposite effects respectively on domestic and foreign firms. In particular, when the market is not concentrated and state aid takes the form of a production subsidy, a stronger substitution among domestic products will reduce the distortions felt by the foreign firm (but increase that felt by domestic rivals); Finally, (iv) the paper demonstrates that the impact of selective State aid on market prices and competitors can depend on the particular characteristics of the market JEL Classification numbers: K21; L10; L40State aids; EU Antitrust; distortions of competition

    The influence of online posting dates on the bibliometric indicators of scientific articles

    This article analyses the difference in timing between the online availability of articles and their corresponding print publication and how it affects two bibliometric indicators: Journal Impact Factor (JIF) and Immediacy Index. This research examined 18,526 articles, the complete collection of articles and reviews published by a set of 61 journals on Urology and Nephrology in 2013 and 2014. The findings suggest that Advance Online Publication (AOP) accelerates the citation of articles and affects the JIF and Immediacy Index values. Regarding the JIF values, the comparison between journals with or without AOP showed statistically significant differences (P=0.001, Mann-Whitney U test). The Spearman's correlation between the JIF and the median online-to-print publication delay was not statistically significant. As to the Immediacy Index, a significant Spearman's correlation (rs=0.280, P=0.029) was found regarding the median online-to-print publication delays for journals published in 2014, although no statistically significant correlation was found for those published in 2013. Most journals examined (n=52 out of 61) published their articles in AOP. The analysis also showed different publisher practices: eight journals did not include the online posting dates in the full-text and nine journals published articles showing two different online posting dates--the date provided on the journal website and another provided by Elsevier's Science Direct. These practices suggest the need for transparency and standardization of the AOP dates of scientific articles for calculating bibliometric indicators for journals

    Analysis of a public repository for the study of automatic fall detection algorithms

    The use of publicly available repositories containing movement traces of real or experimental subjects is a key aspect to define an evaluation framework that allows a systematic assessment of wearable fall detection systems. This papers presents a detailed analysis of a public dataset of traces which employed five sensing points to characterize the user’s mobility during the execution of ADLs (Activities of Daily Living) and emulated falls. The analysis is aimed at analysing two main factors: the importance of the election of the position of the sensor and the possible impact of the user’s personal features on the statistical characterization of the movements. Results reveal the importance of the nature of the ADL for the effectiveness of the discrimination of the falls.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

    The goal of this paper is to analyze the main problems that emerge from the open innovation model. Adopting as analytical framework an organizational perspective we divide the main challenges that arise from the management of open innovation in two main categories: coordination problems as a result of open the innovation system to ideas and knowledge that may lie outside the boundaries of the firm and, incentive problems related with the creation and value capture of ideas an knowledge by the innovator. We describe and analyze several problems related with coordination and incentives.peer-reviewe

    API de Google maps para un mapa de conocimiento de los asesores especializados de un centro de desarrollo empresarial

    Existen sitios dedicados a asesorar a emprendedores y micro empresarios en temas de compras, producción, innovación, ventas, finanzas, etc. Tanto en México, como en otros países, existen los CDE (Centros de Desarrollo Empresarial) otros denominados Incubadoras de Empresas, donde se brinda apoyo a los emprendedores que inician una nueva empresa. En la Universidad Autónoma del Estado de México, se creó una red de Incubadoras de Empresas en los Centros Universitarios, Una de estas unidades se encuentra en el Centro Universitario UAEM Texcoco, donde se enfocó este proyecto. Una de las misiones de los CDE es ofrecer y llevar a cabo asesorías ante los problemas y retos de las empresas nacientes. Para lo anterior se creó una aplicación Web para administrar el conocimiento a través de un Mapa de Conocimiento. Los usuarios pueden consultar la existencia de conocimiento requerido; si existe, lo podrán visualizar en un mapa con ayuda de la API (Interfaz de Programación de Aplicaciones) de Google Maps. Para su uso, basta un dispositivo con conexión a internet. Esta aplicación busca apoyar a emprendedores y empresarios que tiene las preguntas: ¿El CDE Tiene el conocimiento qué requiero? ¿Quién tiene el conocimiento? ¿Dónde están los portadores del conocimiento? ¿Cómo y dónde los contacto? De existir el conocimiento en el mapa bastará contactar a algún portador y establecer una modalidad para la asesoría requerida. Se parte, de la búsqueda de conocimiento, su existencia, ubicación y forma de contactar al portador del conocimiento. Para lo anterior se logró una aplicación capaz de filtrar un tipo de conocimiento y el mapeo sobre la plataforma de la API de Google Maps

    Methodology for the metric restoration of the historical cartography applied to Francisco Coello's cartografic series of the Royal Site of Aranjuez

    Hojas Kilométricas (Kilometric Sheets). Specifically, the study focuses on those sheets referring to the city centre and surrounding area of the Royal Site of Aranjuez, a town in the south of the Province of Madrid. The aim of this study is to restore the actual size and measurements of scanned images of the Hojas Kilométricas. This would allow us, among other things, to reestablish both the format and scale of the original plans. To achieve this goal it is necessary to rectify and then georeference these images, i.e. assign them a geographic reference system. This procedure is essential in the overlaying and comparison of the Hojas Kilométricas of the Royal Site with other historical cartography as well as other sources related to the same area from different time periods. Subsequent research would allow us, for example, to reconstruct the time-evolution of the urban area, to spot new construction and to pinpoint the locations of any altered or missing buildings or architectural features. In addition, this would allow us to develop and integrate databases for GIS models applicable to the management of our cultural heritage

    Optimizing Scan Homogeneity for Building Full-3D Lidars based on Rotating a Multi-Beam Velodyne Rangefinder

    Get PDF
    Multi-beam lidar (MBL) scanners are compact, light, and accessible 3D sensors with high data rates, but they offer limited vertical resolution and field of view (FOV). Some recent robotics research has profited from the addition of a degree-of-freedom (DOF) to an MBL to build rotating multi-beam lidars (RMBL) that can achieve high-resolution scans with full spherical FOV. In a previous work, we offered a methodology to analyze the complex 3D scan measurement distributions produced by RMBLs with a rolling DOF and no pitching. In this paper, we investigate the effect of introducing constant pitch angles in the construction of the RMBLs with the purpose of finding a kinematic configuration that optimizes scan homogeneity with a spherical FOV. To this end, we propose a scalar index of 3D sensor homogeneity that is based on the spherical formulation of Ripley's K function. The optimization is performed for the widely used Puck (VLP-16) and HDL-32 sensors by Velodyne.This work was partially funded by the Spanish project {DPI2015-65186-R}.

    Synchronizing a modular robot colony for cooperative tasks based on intrainter robot communications

    Get PDF
    The implementation of robotic cooperative tasks such as pushing an object toward a desired destination or manipulating an object using mobile robots or robotic arms requires motion coordination between the robot colony. When a robot is built by the union of several robots, such as modular robot systems, it is critical to have the complete coordination of each robot configuration within the colony and also overall robot coordination of the colony. The paper presents a demonstration of parallel motion for modular robot configurations through the combination of two types of communications, i.e., Inter-robot and Intra-robot communications. The two types of communications are described and implemented in a real modular robot system. Experiments are executed to show the performance of the robot colony synchronizatio
