Ordinal mind change complexity of language identification
1997
The approach of ordinal mind change complexity, introduced by Freivalds and Smith, uses constructive ordinals to bound the number of mind changes made by a learning machine. This approach provides a measure of the extent to which a learning machine has to keep revising its estimate of the number of mind changes it will make before converging to a correct hypothesis for languages in the class being learned. Recently, this measure, which also suggests the difficulty of learning a class of languages, has been used to analyze the learnability of rich classes of languages. Jain and Sharma have shown that the ordinal mind change complexity for identification from positive data of languages formed…
A GPU-Based DVC to H.264/AVC Transcoder
2010
Mobile to mobile video conferencing is one of the services that the newest mobile network operators can offer to users With the apparition of the distributed video coding paradigm which moves the majority of complexity from the encoder to the decoder, this offering can be achieved by introducing a transcoder This device has to convert from the distributed video coding paradigm to traditional video coding such as H.264/AVC which is formed by simpler decoders and more complex encoders, and allows to the users to execute only the low complex algorithms In order to deal with this high complex video transcoder, this paper introduces a graphics processing unit based transcoder as base station The…
High-resolution far-field integral-imaging camera by double snapshot
2012
In multi-view three-dimensional imaging, to capture the elemental images of distant objects, the use of a field-like lens that projects the reference plane onto the microlens array is necessary. In this case, the spatial resolution of reconstructed images is equal to the spatial density of microlenses in the array. In this paper we report a simple method, based on the realization of double snapshots, to double the 2D pixel density of reconstructed scenes. Experiments are reported to support the proposed approach.
Adapting hierarchical bidirectional inter prediction on a GPU-based platform for 2D and 3D H.264 video coding
2013
The H.264/AVC video coding standard introduces some improved tools in order to increase compression efficiency. Moreover, the multi-view extension of H.264/AVC, called H.264/MVC, adopts many of them. Among the new features, variable block-size motion estimation is one which contributes to high coding efficiency. Furthermore, it defines a different prediction structure that includes hierarchical bidirectional pictures, outperforming traditional Group of Pictures patterns in both scenarios: single-view and multi-view. However, these video coding techniques have high computational complexity. Several techniques have been proposed in the literature over the last few years which are aimed at acc…
La procesión del Corpus en Sevilla: influencias sociales y políticas en la evolución del cortejo
2007
This paper deals about the changes happened in the procession of the Corpus Christi in Seville. We have news of that from 1363, and along the following centuries, but the most interesting is the way the procession is represented by two series of drawings one from 1747, and the other from 1866. This two series allow us to see the differences between them, that were due mainly to the politic, social, and religious changes. Se trata en este artículo sobre los cambios ocurridos en la procesión del Corpus Christi en Sevilla. La primera noticia es de 1363, y a partir de esta fecha se conocen bastantes acontecimientos en los siglos siguientes, pero lo más interesante es la manera en que se represe…
El árbol. Protagonista del paisaje de fin de siglo
2007
A finales del siglo XIX, la necesidad de reflejar en las obras contenidos más sencillos y cercanos al espectador, ocasionó en todos los géneros, en general, y en el paisaje, en particular, una nueva forma de ver y entender la obra de arte. Las salidas frente al natural enfrentaron a los artistas cara a cara con la Naturaleza, aprendiendo a observarla con todo detalle y trasladarla con la mayor fidelidad posible al lienzo. Y dentro de las especies vegetales, fue sin duda, el árbol el que concentró todas las miradas, siendo él el verdadero protagonista del paisaje de fin de siglo. Y así como en el resto de las especies no resulta posible realizar un análisis concreto, en el estrato arbóreo se…
Icarus and Daedalus in Toni Morrison's "Song of Solomon"
2012
In Song of Solomon Toni Morrison rewrites the legend of the Flying Africans and the Myth of Icarus to create her own Myth. Her depiction of the black hero’s search for identity has strong mythical overtones. Morrison rescues those elements of mythology black culture which are still relevant to blacks and fuses them with evident allusions to Greek mythology. She reinterprets old images and myths of flight, the main mythical motif in the story. Her Icarus engages on an archetypical journey to the South, to his family past, led by his Daedalic guide, on which he finally recovers his ancestral ability to fly. His flight signals a spiritual epiphany in the hero’s quest for self-definition in the…
Multimodal approach to foster the Multiliteracies pedagogy in the teaching of EFL through picturebooks: The Snow Lion
2020
espanolEnsenar lenguas en el siglo veintiuno implica prestar atencion a las demandas pedagogicas multimodales de un mundo digital global. Para alcanzar este objetivo, la ensenanza efectiva del ingles requiere una preparacion de los instructores para guiar de manera consciente el desarrollo de la literacidad de los alumnos e integrar las distintas maneras de construir significado que van mucho mas alla del mero uso de la lengua. Este articulo suscribe la nocion de literacidad como un concepto multidimensional y propone un conjunto de herramientas multimodales como medio para que los maestros de ingles como lengua extranjera (ILE) trabajen con elementos literarios y visuales clave. Centrandon…

Based on recent studies on materiality, picturebook research, and cognitive studies, this paper investigates how children may perceive picturebooks as objects and their material properties. In this regard, we emphasise three dimensions of picturebooks as objects and relate them to developmental stages. The first dimension concerns the materials the picturebooks are composed of, such as paper, cardboard, wood, plastics, and cloth. The second dimension refers to the type of book, e.g. hardbacks, sets of cardboard sheets, fanfold books, pop-up books, and even hybrid objects such as books which are toys at the same time. Finally, this study focuses on the types of actions that are associated wi…
PDB: A pictorial database oriented to data analysis
1993
The paper describes a new pictorial database oriented to image analysis, implemented inside the MIDAS data analysis system. Pictorial databases need expressive data structures in order to represent a wide class of information from the numerical to the visual. The model of the database is relational; however, a full normalization is not achievable, owing to the complexity of the visual information. The paper reports the general design and notes on the software implementation. Preliminary experiments show the performance of the pictorial database. Copyright © 1993 John Wiley & Sons, Ltd
