The contribution of pomeron fusion to the cross section of η and η productions in double-diffractive scattering has been calculated within the Donnachie-Landshoff model of pomeron. It is shown that the double pomeron exchange mechanism does not explain the full set of the recent data of WA102 Collaboration, though it might not be inconsistent with η productions. On leave of absence from Institu...

In the framework of the double-pushout approach to graph grammars, we propose a new notion of parallel composition, called synchronized composition, of production applications. Our aim is to allow (pairs of) productions which are possibly not parallel independent, to be applied in parallel, provided that they are not mutually exclusive.The notion of synchronized composition we propose is not co...

The purpose of this paper is the bibliometric analysis journals indexed in SciELO area teaching and learning English as a second language. searched were: How, Profile, Colombian Applied Linguistics Journal. search for information made it possible to compare different indicators. Although true that results research show scientific production field abundant, varied terms thematic lines, collabora...

In a context of increase in content and actors on the Internet, museum’s websites are publishing resources for diffusion of arts and sciences, but also for their promotion and for communication. The option to limit interactivity is taken to provide verified data, included in a slow temporality compared to the temporality of the Internet and more recently of the web 2.0, but this is made without...

OBJECTIVE To analyze scientific productions about the relationship between HIV and Systemic Arterial Hypertension (SAH) in people living with HIV/AIDS (PLWHA). METHOD Integrative literature review in six databases, held in March 2016. "AIDS" and "hypertension" were the keywords used in Portuguese, English and Spanish languages. We found 248 articles and selected 17. The categories formulated ...

Rich and fine-grained semantic information describing varied aspects of scientific productions is essential to support their diffusion as well as to properly assess the quality of their output. To foster this trend, in the context of the ESWC2014 Semantic Publishing Challenge, we present a system that automatically generates rich RDF datasets from CEUR-WS workshop proceedings. Proceedings are a...

The electroweak production processes of vector bosons, e+e− → Zγ, γe → Ze, and γe → Wν are considered simultaneousely and in the Standard model the covariant polarization density matrices of vector bosons for these processes are obtained explicitly from one of the processes, γe → Ze. The effect of the photon polarization as well as the vector meson polarization is considered and some special ca...

Instead of the expansion of the information retrieval systems, the music information retrieval domain is still an open one. In this context, the singing voice classification is a promised trend. In this paper, we shall present our experiments concerning the classification of singers according to their voice type, and their voice quality. Some experiments were carried in which two sets of parame...

We define ShapeShifting programmes as interactive and reconfigurable moving image productions that adapt their content, on the fly, to suit the preferences of the viewers or engagers. They are automatically edited at the time of delivery. We have developed a paradigm, a computational model and an accompanying software system for the creation and delivery of ShapeShifting Screen Media programmes...
