Carlos García Prada: Poetas modernistas hispanoamericanos

En un discurso pronunciado hace algún tiempo en la Academia Colombiana de la Lengua, el doctor Eduardo Santos, después de glosar la "Historia y Antología de la Poesía Castellana, del siglo XII al XX" publicada por la Casa Aguilar en 1946, consigna esta afirmación optimista

Tracking-Based Non-Parametric Background-Foreground Classification in a Chromaticity-Gradient Space

This work presents a novel background-foreground classification technique based on adaptive non-parametric kernel estimation in a color-gradient space of components. By combining normalized color components with their gradients, shadows are efficiently suppressed from the results, while the luminance information in the moving objects is preserved. Moreover, a fast multi-region iterative tracking strategy applied over previously detected foreground regions allows to construct a robust foreground modeling, which combined with the background model increases noticeably the quality in the detections. The proposed strategy has been applied to different kind of sequences, obtaining satisfactory results in complex situations such as those given by dynamic backgrounds, illumination changes, shadows and multiple moving objects

Carlos Lozano y Lozano: obra escogida

La presente obra se divide en dos secciones. La primera presenta una visión de la vida y la obra de Carlos Lozano y Lozano y en la segunda aparecen algunos de sus escritos más notables, especialmente los que muestran su visión de los terrenos del derecho y de la historia. En la primera parte se mencionan algunos datos sobre la familia de Lozano, tras lo cual se recorre sus estudios en el Colegio del Rosario; donde fue alumno, colegial y secretario. En 1925 se retira del Rosario para viajar al Perú, donde su padre Fabio Lozano Torrijos se desempeñaba como Embajador. Lozano continúa sus estudios en Italia y en Francia y vuelve a Colombia, en postrimerías de la llamada República Conservadora, para ocupar un puesto de vanguardia en las posiciones del Estado colombiano, principalmente del Parlamento, durante el primer gobierno de López Pumarejo, para desempeñar la Legalización de Colombia entre el gobierno de Francia. En el siguiente gobierno, de Eduardo Santos, ocupó el Ministerio de Justicia y la embajada de Colombia ante el gobierno del Brasil, donde alcanzó altísimos reconocimientos tanto en el terreno diplomático como en el cultural

Gaining further insight into photo-Fenton treatment of phenolic compounds commonly found in food processing industry

A mixture of eight phenolic compounds, namely 2,4-dinitrophenol, tannic, ellagic, gallic, protocatechuic, vanillic, syringic and sinapic acids, have been treated by means of a photo-Fenton process under simulated and real sunlight. An experimental design methodology, based in Doehlert matrixes, was employed to check the effect of the concentration of Fe(II) and H2O2, as well as pH. Response surfaces show that photo-Fenton can be extended to pH values clearly above 2.8, probably due to complexation of iron with the phenolic substances. Experiments performed under solar irradiation at pH = 3.9 showed that complete removal of the monitored pollutants was achieved in less than 3 min; mineralisation was also efficient, although some organics remained in the solution. Toxicity was monitored according to Pseudokirchneriella subcapitata and Daphnia magna bioassays; Recombinant Yeast Assay (RYA) was employed to assess estrogenic and dioxin-like activities. 2,4-Dinitrophenol was demonstrated to be the major concern and, in general, photo-Fenton resulted in a detoxification of the solution. Finally, excitation emission matrix (EEM) fluorimetry was employed to obtain complementary information on the behaviour of organic matter. Most peaks associated with the parent pollutants disappeared after short irradiation periods and, at 12 min of irradiation chromophores were destroyed, what can be associated with the removal of complex molecules.

Domingo García, ensemble rupestre

Le siteL’ensemble gravé de plein air de Domingo García se trouve sur la commune de Santa María la Real de Nieva (Ségovie, Castille-et-León, Espagne) au sud-est de la dépression du Duero dans la vallée de l’Eresma, un affluent de la rive gauche du Duero, à un peu plus de 40 km au nord-est de la ville de Ségovie. Cet ensemble s’étend sur plus de 110 km2 (Santos 2013 : 264) et compte au moins cinq sites contenant des gravures paléolithiques (Ripoll & Municio 1999 : 59-196, 2001 : 183, Pecci 201..

Real-time shot detection based on motion analysis and multiple low-level techniques

To index, search, browse and retrieve relevant material, indexes describing the video content are required. Here, a new and fast strategy which allows detecting abrupt and gradual transitions is proposed. A pixel-based analysis is applied to detect abrupt transitions and, in parallel, an edge-based analysis is used to detect gradual transitions. Both analysis are reinforced with a motion analysis in a second step, which significantly simplifies the threshold selection problem while preserving the computational requirements. The main advantage of the proposed system is its ability to work in real time and the experimental results show high recall and precision values
