Leer juntos.

Presenta la experiencia de animación a la lectura titulada 'Leer juntos' llevada a cabo en el pueblo aragonés Ballolar, en la que participan el CEIP Francisco Gaia y Sarañana, la bibliotecaria, los padres, los alumnos y los habitantes del pueblo. La bibliotecaria selecciona libros, que los habitantes intercambian en la panadería del pueblo, y mensualmente se comentaran las lecturas en una tertulia, o se realizan actividades como la visita de escritores. En las clases los alumnos también comentan los libros y realizan actividades sobre ellos. Finaliza con la expansión de esta iniciativa a otros pueblos de la comarca.

La enseñanza de las lenguas clásicas en Europa.

Exposición de los motivos por los que se suprime la enseñanza de las lenguas clásicas en los planes de estudio europeos. La crisis comienza a finales del siglo XVIII con la extensión de las lenguas vulgares, el aprendizaje del latín ya no es necesario para el estudio de las demás disciplinas. Ante esta situación surgen voces que defienden el estudio de estas lenguas no como idiomas, sino como disciplinas educativas, ya que al mismo tiempo se aprende la cultura, la civilización de un pueblo. El problema viene por el exceso de carga lectiva de los alumnos, que obliga a elegir entre la necesidad de información moderna o la cultura clásica. Ante esta disyuntiva se opta por elegir una de las dos lenguas clásicas para los planes de estudio: la latina o la griega. Unos abogan por la originalidad del griego, otros por la mayor cercanía del latín a nuestra cultural. Se opta finalmente por incluir el latín en los planes de estudios por su ventaja de parentesco con la lengua materna, y dejar el griego sólo para los alumnos mejor dispuestos para su estudio, de forma opcional. Sin embargo, los resultados obtenidos en el estudio del latín no son los esperados y de ello se desprende la irremediable conclusión de que debe desterrarse del planes de estudio también el latín para determinado tipo de alumnos. Así pues, surgen los diferentes bachilleratos: uno formado por ciencias e idiomas modernos, otro basado en letras y lenguas clásicas, y uno intermedio, según las aptitudes de los estudiantes.

Evaluar para compartir metas.

Se presenta el proyecto 'Evaluar para Compartir Metas' desarrollado entre 2003-2006 en el colegio Padre Collado de la localidad de Telde (Las Palmas). Mediante este proyecto se pretenden detectar los factores relacionados con la comunicación y la convivencia que es necesario potenciar, y aquellos otros que entorpecen el logro de los objetivos educativos. Finalmente se valora dicha experiencia y se definen las fases en las que se ha desarrollado este proceso: en la primera de ellas se ha realizado la evaluación y en la siguiente se ha elaborado el plan de mejora.

A meta-analysis of 16 randomized trials of sirolimus-eluting stents versus paclitaxel-eluting stents in patients with coronary artery disease

OBJECTIVES: Our purpose was to make a synthesis of the available evidence on the relative efficacy and safety of 2 drug-eluting stents (DES)--sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES)--in patients with coronary artery disease. BACKGROUND: It is not known whether there are differences in late outcomes between the 2 most commonly used DES: SES and PES. METHODS: Sixteen randomized trials of SES versus PES with a total number of 8,695 patients were included in this meta-analysis. A full set of individual outcome data from 5,562 patients was also available. Mean follow-up period ranged from 9 to 37 months. The primary efficacy end point was the need for reintervention (target lesion revascularization). The primary safety end point was stent thrombosis. Secondary end points were death and recurrent myocardial infarction (MI). RESULTS: No significant heterogeneity was found across trials. Compared with PES, SES significantly reduced the risk of reintervention (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.63 to 0.87, p < 0.001) and stent thrombosis (HR 0.66; 95% CI 0.46 to 0.94, p = 0.02) without significantly impacting on the risk of death (HR 0.92; 95% CI 0.74 to 1.13, p = 0.43) or MI (HR 0.84; 95% CI 0.69 to 1.03, p = 0.10). CONCLUSIONS: Sirolimus-eluting stents are superior to PES in terms of a significant reduction of the risk of reintervention and stent thrombosis. The risk of death was not significantly different between the 2 DES, but there was a trend toward a higher risk of MI with PES, especially after the first year from the procedure.

UAS See-and-Avoid Strategy using a Fuzzy Logic Controller Optimized by Cross-Entropy in Scaling Factors and Membership Functions

This work aims to develop a novel Cross-Entropy (CE) optimization-based fuzzy controller for Unmanned Aerial Monocular Vision-IMU System (UAMVIS) to solve the seeand- avoid problem using its accurate autonomous localization information. The function of this fuzzy controller is regulating the heading of this system to avoid the obstacle, e.g. wall. In the Matlab Simulink-based training stages, the Scaling Factor (SF) is adjusted according to the specified task firstly, and then the Membership Function (MF) is tuned based on the optimized Scaling Factor to further improve the collison avoidance performance. After obtained the optimal SF and MF, 64% of rules has been reduced (from 125 rules to 45 rules), and a large number of real flight tests with a quadcopter have been done. The experimental results show that this approach precisely navigates the system to avoid the obstacle. To our best knowledge, this is the first work to present the optimized fuzzy controller for UAMVIS using Cross-Entropy method in Scaling Factors and Membership Functions optimization.

OMNIWORKS: Omnidirectional vision for human-UAV co-working

The OMNIWORKS project objective is to develop an autonomous and modular aerial inspection system for an off-shore meteorological mast up to 90m in length. The UAV was equipped with an omni-directional camera and vertical take-off/landing capabilities that should be simple enough to operate as to not need the interventions of a professional pilot under challenging situations. Therefore the tests included different aspects used to evaluate both the technical performance of the UAV behavior as well as the operators? point of view.

Robust Real-time Vision-based Aircraft Tracking From Unmanned Aerial Vehicles.

Aircraft tracking plays a key and important role in the Sense-and-Avoid system of Unmanned Aerial Vehicles (UAVs). This paper presents a novel robust visual tracking algorithm for UAVs in the midair to track an arbitrary aircraft at real-time frame rates, together with a unique evaluation system. This visual algorithm mainly consists of adaptive discriminative visual tracking method, Multiple-Instance (MI) learning approach, Multiple-Classifier (MC) voting mechanism and Multiple-Resolution (MR) representation strategy, that is called Adaptive M3 tracker, i.e. AM3. In this tracker, the importance of test sample has been integrated to improve the tracking stability, accuracy and real-time performances. The experimental results show that this algorithm is more robust, efficient and accurate against the existing state-of-art trackers, overcoming the problems generated by the challenging situations such as obvious appearance change, variant surrounding illumination, partial aircraft occlusion, blur motion, rapid pose variation and onboard mechanical vibration, low computation capacity and delayed information communication between UAVs and Ground Station (GS). To our best knowledge, this is the first work to present this tracker for solving online learning and tracking freewill aircraft/intruder in the UAVs.

Real-Time Adaptive Multi-Classifier Multi-Resolution Visual Tracking Framework for Unmanned Aerial Vehicles

This paper presents a novel robust visual tracking framework, based on discriminative method, for Unmanned Aerial Vehicles (UAVs) to track an arbitrary 2D/3D target at real-time frame rates, that is called the Adaptive Multi-Classifier Multi-Resolution (AMCMR) framework. In this framework, adaptive Multiple Classifiers (MC) are updated in the (k-1)th frame-based Multiple Resolutions (MR) structure with compressed positive and negative samples, and then applied them in the kth frame-based Multiple Resolutions (MR) structure to detect the current target. The sample importance has been integrated into this framework to improve the tracking stability and accuracy. The performance of this framework was evaluated with the Ground Truth (GT) in different types of public image databases and real flight-based aerial image datasets firstly, then the framework has been applied in the UAV to inspect the Offshore Floating Platform (OFP). The evaluation and application results show that this framework is more robust, efficient and accurate against the existing state-of-art trackers, overcoming the problems generated by the challenging situations such as obvious appearance change, variant illumination, partial/full target occlusion, blur motion, rapid pose variation and onboard mechanical vibration, among others. To our best knowledge, this is the first work to present this framework for solving the online learning and tracking freewill 2D/3D target problems, and applied it in the UAVs.
