La Compañía Iberoamericana de Publicaciones, primera gran corporación editorial en castellano

La Compañía Iberoamericana de Publicaciones (CIAP) fue una empresa editorial española de insólita modernidad y proporciones en su tiempo. Hace su aparición en un momento, primer tercio del siglo xx, en que la industria del libro conoce aires modernizadores y adquiere características que permite que por vez primera se pueda hablar de «capitalismo de la edición». La CIAP revolucionó el mercado editorial hispano con una serie de iniciativas adelantadas a su tiempo, tales como los contratos con los autores en exclusiva, que dignificaron la profesión de escritor en España, el uso intensivo de la publicidad, la instauración de premios literarios, etc. El experimento empresarial terminó, sin embargo, en una quiebra estrepitosa, que se llevó por delante a la casa Bauer y puso en evidencia las posibilidades reales del sector

Segment-based interactive-predictive machine translation

[EN] Machine translation systems require human revision to obtain high-quality translations. Interactive methods provide an efficient human¿computer collaboration, notably increasing productivity. Recently, new interactive protocols have been proposed, seeking for a more effective user interaction with the system. In this work, we present one of these new protocols, which allows the user to validate all correct word sequences in a translation hypothesis. Thus, the left-to-right barrier from most of the existing protocols is broken. We compare this protocol against the classical prefix-based approach, obtaining a significant reduction of the user effort in a simulated environment. Additionally, we experiment with the use of confidence measures to select the word the user should correct at each iteration, reaching the conclusion that the order in which words are corrected does not affect the overall effort.The research leading to these results has received funding from the Ministerio de Economia y Competitividad (MINECO) under Project CoMUN-HaT (Grant Agreement TIN2015-70924-C2-1-R), and Generalitat Valenciana under Project ALMAMATER (Ggrant Agreement PROMETEOII/2014/030).Domingo-Ballester, M.; Peris-Abril, Á.; Casacuberta Nolla, F.

Interactive neural machine translation

This is the author’s version of a work that was accepted for publication in Computer Speech & Language. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Computer Speech & Language 00 (2016) 1 20. DOI 10.1016/j.csl.2016.12.003.Despite the promising results achieved in last years by statistical machine translation, and more precisely, by the neural machine translation systems, this technology is still not error-free. The outputs of a machine translation system must be corrected by a human agent in a post-editing phase. Interactive protocols foster a human computer collaboration, in order to increase productivity. In this work, we integrate the neural machine translation into the interactive machine translation framework. Moreover, we propose new interactivity protocols, in order to provide the user an enhanced experience and a higher productivity. Results obtained over a simulated benchmark show that interactive neural systems can significantly improve the classical phrase-based approach in an interactive-predictive machine translation scenario. c 2016 Elsevier Ltd.

Diseño y control de una Rotomoldeadora

El uso de materiales livianos dentro de la industria está vinculado a una fuerte estrategia de negocio esto ya que a la hora de diligenciar una nueva negociación en cualquier industria a cualquier cliente, el acabado a los productos terminados tienen una relación directamente proporcional a la oportunidad de concretarlo, entre más calidad tenga el producto en su presentación final mayor será la ventaja competitiva de la industria manufacturera. En el mercado convencional las piezas plásticas están de manera restringida a un estándar, normalmente para una nueva configuración dependiendo la necesidad se debe iniciar un desarrollo para lograrla. En el mundo de la industria, la necesidad de usar piezas plásticas es cada vez mayor, esto es por las diferentes formas que este material permite y que en el producto final significa un peso y precio menor, en las pequeñas industrias la adquisición de este tipo de materia prima es a través de un proveedor externo ya que no se cuenta con la maquinaria adecuada para realizarlo de manera interna

Defining Adaptive Learning Paths For Competence-Oriented Learning

This paper presents a way to describe educational itineraries in a competence-oriented learning system in order to solve the problem of sequencing several independent courses. The main objective is to extract adaptive learning paths composed by the subset of needed courses passed in the right order. This approach improves the courses’ re-usability allowing courses to be included in different itineraries, improving the re-usability of the courses, and making possible the definition of mechanisms to adapt the learning path to the learner’s needs in execution tim

Evolución paleoambiental de la formación Río Mayer, Cretácico inferior, Cuenca Austral, provincia de Santa Cruz, Argentina

La Formación Río Mayer es parte del relleno inicial de la Cuenca Austral, la cual se ubica en el sector más austral de la Patagonia. El área de estudio se encuentra entre los lagos San Martín y Argentino (Provincia de Santa Cruz), donde se relevaron diez perfiles sedimentológicos de detalle en los que se describieron 18 facies sedimentarias. Estas facies responden a diferentes procesos sedimentarios, principalmente autigénicos, hemipelágicos y episódicos. A partir de la distribución de las facies y del origen del material fósil se reconocieron tres paleoambientes sedimentarios: marino de plataforma externa, marino de plataforma externa con influencia deltaica y prodelta. El análisis de la distribución espacial y temporal de las facies condujo a la elaboración de un esquema de evolución paleoambiental para el Cretácico Inferior de la Cuenca Austral en la zona estudiada. La depositación de la Formación Río Mayer, por encima de la Formación Springhill, en el área de la Seccional Río Guanaco, comenzó durante el Berriasiano. En el Valanginiano la transgresión generó los depósitos incluidos en la Formación Springhill en la región de Lago San Martín, mientras que en el intervalo Hauteriviano-Barremiano toda el área de estudio presentaba características de plataforma externa distal. Durante el lapso temporal Aptiano-Albiano, se produjo la instalación de un sistema deltaico (Formación Piedra Clavada / Kachaike) en el norte del área de estudio entre los lagos San Martín y Viedma. Para este intervalo temporal la Formación Río Mayer en las regiones de Lago San Martín y Estancia La Vega, representa un ambiente de prodelta. Paralelamente, en la región sur del área de estudio se produjo la sedimentación de los niveles incluidos en un ambiente de plataforma externa influenciada por flujos turbidíticos distales de frente deltaico. Finalmente durante el Albiano superior-Cenomaniano inferior se desarrolló una transgresión marina, que marca el comienzo de la etapa de antepaís de la Cuenca Austral. En la región de los lagos San Martín y Viedma, la transgresión está evidenciada por los depósitos litorales de la Formación Mata Amarilla, mientras que en la región de Río Guanaco es representada por los depósitos de la Formación Cerro Toro.The marine deposits of the Río Mayer Formation are part of the initial filling of the Austral Basin, which is developed in the southernmost part of South America, including the south of Chile and Argentina (southwestern Patagonia, Santa Cruz and Tierra del Fuego Provinces, Figs. 1, 2). The study area is located between the San Martín and Argentino lakes in the Santa Cruz Province (Fig. 3). The Río Mayer Formation (Fig. 2) was studied in three main localities, where detailed sedimentary logging was undertaken (Figs. 4, 5), taking into account the lithology, the primary sedimentary structures, the palaeontological content, rock bodies geometry, their orientation and the hierarchy as well as the contacts with underlying and overlying units. Eighteen sedimentary facies were defined (Figs. 6, 7; Table 1), which were grouped into three facies association representing different sedimentary palaeoenvironments, like marine outer platform (AF 1), marine outer platform influenced by a deltaic system (AF 2) and prodelta (AF 3) (Fig. 8, Tables 1, 2). The facies of the outer platform palaeoenvironment corresponds to the rocks traditionally assigned to the Río Mayer Formation, according to the available bibliography, and deposited by hemipelagic and authigenic processes interrupted by episodic sedimentation. The deposits of the outer platform influenced by a deltaic system palaeoenvironment are similar to the above mentioned but presents continental fossils that indicate a deltaic source. Finally, AF 3 of a prodelta palaeoenvironment is dominated by sandy/heterolithics levels associated with turbidity currents and hyperpycnal flows originated in a delta front. The best and most complete exposures of the unit were observed in the Río Guanaco locality, where palaeoenvironmental interpretations were performed, allowing the division of the 350 m-thick unit in three sections (Fig. 9). The lower section is composed mainly by black shales with both tabular and concretional marls levels (AF 1). Trace fossils are not recorded in this section, but ammonites, belemnites and bivalves are frequent. It has been interpreted as accumulated in a distal platform, under anoxic conditions. The middle section is characterized by bioturbated black marls and shales, with wellpreserved Zoophycos ichnofacies (Richiano et al., in press), occurring in a distal platform depositional environment. Body fossils are frequent, especially belemnites. The upper section is composed of massive black mudstones with intercalations of very fine- to fine-grained sandstones and less frequent conglomerates. In this section both debris flows and distal low-density turbidity current deposits were identified. Zoophycos ichnofacies and Ophiomorpha rudis ichnosubfacies were recognized in association with molds of petrified wood containing Teredolites isp. (Richiano et al., in press). The presence of turbulent currents and large trace fossils suggest a more oxygenated conditions. At Lago San Martín and Estancia La Vega localities the most significant characteristic is the presence of prodeltaic deposits in the transition between Río Mayer Formation and Piedra Clavada formations (Fig. 9). To sum up, after the Upper Jurassic rifting stage of the Austral Basin, the Springhill Formation represents the initial infill of the extensional structures. After that, during the Berriasian (Fig. 10a), the levels of the lower section of the Río Mayer Formation started to accumulate in the Río Guanaco area. During the Valanginian (Fig. 10b), an acceleration in the transgression generated the accumulation of the Springhill Formation in the Lago San Martín area while in the Río Guanaco region the middle section of the Río Mayer Formation developed. Between the Hauterivian and the Barremian all the study area was under distal platform conditions (Fig. 10c). A major change in the sedimentary systems of the Austral Basin during the Lower Cretaceous is the development of the deltaic Piedra Clavada Formation (Fig. 10d). This event generated two different palaeoenvironments in the Río Mayer Formation. Prodeltaic deposits are present to the north, while sediments of distal platform conditions with highly frequent sandy levels prevail southwards. Finally a new transgression indicates the beginning of the Cerro Toro and Mata Amarilla formations in the middle Albian- lower Cenomanian (Fig. 10e).Fil: Richiano, Sebastián Miguel.

Using Sewage-Sludge Ash as Filler in Bituminous Mixes

In this study, the behavior of bituminous mixes made with sewage sludge ash (SSA) as mineral filler was investigated. The behavior of these mixes was evaluated with the Cantabro, indirect tensile strength, water sensitivity, permanent deformation, and resilient modulus tests. The results show that SSA waste may be used in bituminous mixes at approximately 2–3% weight percent, maintaining adequate levels of cohesion and adhesion in the mixtures, which is comparable to mixtures made with active fillers such as hydrated lime and cement. Moreover, its use does not increase permanent deformations. However, the resilient modulus test gave slightly lower results for mixes made with SSA than for mixtures made with other fillers. It may be concluded that SSA waste may be used as a filler for bituminous mixes with better results than for mixes made with limestone fillers and with similar results for mixes made with other fillers such as hydrated lime and cement.This work has been financed by the University of Alicante through projects VIGROB-256 and GRE10-28 and by the Valencian Provincial government through Project GV/2012/113

Performance of Algorithms for Interval Discretization of Biomedical Signals

A methodology to quantify the dependence be tween features using the Ameva discretization algorithm and the advantages of qualitative models is presented in this paper. This approach will be applied over medical data sets. A com parison among Ameva and other related works has been done. The results, as will be depth explained in this paper, show that Ameva-based methodology can be used to determine the depen dence between features in a fast and understandable way from data sets with a high number of attributes and low number of instances. This is a quite important feature in genomic en vironments among others. This methodology has been applied to some well-known medical data sets and the results obtained shown that is a good alternative to other established algorithms in terms of clarity and computational cost.Ministerio de Economía y Competitividad TIN2013-46801-C4-1-RJunta de Andalucía TIC-8052 (Simon
