This research aims to advance blinking detection in the context of work activity. Rather than patients having to attend a clinic, blinking videos can be acquired in a work environment, and further automatically analyzed. Therefore, this paper presents a methodology to perform the automatic detection of eye blink using consumer videos acquired with low-cost web cameras. This methodology includes the detection of the face and eyes of the recorded person, and then it analyzes the low-level features of the eye region to create a quantitative vector. Finally, this vector is classified into one of the two categories considered —open and closed eyes— by using machine learning algorithms. The effectiveness of the proposed methodology was demonstrated since it provides unbiased results with classification errors under 5%

In more scientific terms, NET Station contributed to: - discuss in theoretical terms the role radio still play in contemporary societies; - examine how audiences are using sound resources on the Web; - draw up a new theoretical framework for the study of the reconfiguration of radio language on the Internet;acknowledge that people are not abandoning radio as a medium; the survey applied by the team demonstrated that there is a complementariness between traditional radio and radio on the Internet; - understand that people expect more interactivity, more opportunities to participate in content production and more diversity of contents. These results were shared with editors responsible for Portuguese radio and might influence the offer made available by these radio corporations from now on; - demonstrate that the Internet is underexplored in terms of sound and acoustic communication; - promote the production of new sound narratives to be available on the Internet;

Recently, there has been a growing interest in the field of metabolomics, materialized by a remarkable growth in experimental techniques, available data and related biological applications. Indeed, techniques as Nuclear Magnetic Resonance, Gas or Liquid Chromatography, Mass Spectrometry, Infrared and UV-visible spectroscopies have provided extensive datasets that can help in tasks as biological and biomedical discovery, biotechnology and drug development. However, as it happens with other omics data, the analysis of metabolomics datasets provides multiple challenges, both in terms of methodologies and in the development of appropriate computational tools. Indeed, from the available software tools, none addresses the multiplicity of existing techniques and data analysis tasks. In this work, we make available a novel R package, named specmine, which provides a set of methods for metabolomics data analysis, including data loading in different formats, pre-processing, metabolite identification, univariate and multivariate data analysis, machine learning, and feature selection. Importantly, the implemented methods provide adequate support for the analysis of data from diverse experimental techniques, integrating a large set of functions from several R packages in a powerful, yet simple to use environment. The package, already available in CRAN, is accompanied by a web site where users can deposit datasets, scripts and analysis reports to be shared with the community, promoting the efficient sharing of metabolomics data analysis pipelines.

L’objecte central del present informe és descriure l’estat de la qüestió –tant a Catalunya com a altres països– de l’accés als recursos web des de les biblioteques. De fet, l’objectiu últim és presentar i analitzar la situació a l’estranger per tal d’adaptar les estratègies i els models de tractament i organització de recursos web a la realitat i les necessitats de les biblioteques catalanes.

The Centre de Supercomputació de Catalunya (CESCA) together with the Consorci de Biblioteques Universitàries de Catalunya (CBUC) started in 1999 a cooperative repository, named TDR, to file in digital format the full-text of the read thesis at the universities of our country to spread them worldwide in open access preserving the intellectual copyright of the authors. This became operational in 2001 and today it is a service fully consolidated not only among the Catalan universities, but also used by other Spanish universities. Since then, there are four additional cooperative repositories which have been created: RECERCAT, for research papers; RACO, for scientific, cultural and erudite Catalan magazines; PADICAT, for archiving Catalan web sites; and MDC, for Catalan digital collections of pictures, maps, posters, old magazines... These five repositories have some common characteristics: they are open access, that is, they are accessible on the internet for free; they mostly comply with the Open Archive Initiative interoperability protocol for facilitating the efficient dissemination of content; and they have been built in a cooperative manner so that it is easy to adopt common procedures and to share the repository developing and managing costs, it permits more visibility of the indexed documents throughout the search engines, and a better provision for long-term preservation can be made. In this paper we present the common policy established for the Catalan cooperative repositories, we describe the five of them briefly, and we comment on the results obtained of our 6-year experience since the first one became operational.

Aquesta memòria tracta sobre el procediment de creació software que s’ha dut a terme per a implementar el portal web de l’IES Pla d’En Boet de Mataró, un institut públic subvencionat per la Generalitat de Catalunya. Aquest portal s’ha desenvolupat des de zero i s’ha hagut d’enllaçar amb altres aplicacions que han sigut requerides. El document conté l’anàlisi, disseny i l’implementació del portal web, i de tota la funcionalitat que l’envolta, que s’ha realitzat per satisfer els requeriments inicials. Conté, a més, les diferents anàlisis que s’han necessitat per tal d’integrar-lo amb una aplicació pròpia del centre i amb un sistema d’intercanvi de missatges, i com s’ha decidit fer-ho. S’intenta explicar alguna de les problemàtiques més importants que han aparegut al llarg del procés i que han afectat al seu desenvolupament. Les decisions preses per a resoldre-les també apareixen per avalar l’estudi realitzat. Finalment hi ha una valoració personal i una altra dels objectius aconseguits per veure que s’ha arribat a la solució final amb èxit.

Counting labelled planar graphs, and typical properties of random labelled planar graphs, have received much attention recently. We start the process here of extending these investigations to graphs embeddable on any fixed surface S. In particular we show that the labelled graphs embeddable on S have the same growth constant as for planar graphs, and the same holds for unlabelled graphs. Also, if we pick a graph uniformly at random from the graphs embeddable on S which have vertex set {1, . . . , n}, then with probability tending to 1 as n → ∞, this random graph either is connected or consists of one giant component together with a few nodes in small planar components.

Aquest projecte té com a objectiu el desenvolupament d'un site web amb la possibilitat que la gestió del seu contingut fos administrat per persones alienes a la implementació de la web. Aquesta fita ha estat duta a terme en una web d'una entitat esportiva, la Unió Esportiva Sant Cugat, des d'on durant 2 anys i mig s'ha gestionat la informació i comunicació a través de la xarxa amb aquest mitjà. L'estructuració del projecte ha estat totalment modular, per d'aquesta manera facilitar el dinamisme de canvis de possibles continguts que es poden incorporar a la web de manera molt ràpida i senzilla.

Aquest projecte es presenta com una solució al problema aparegut per la implantació de l'estació clínica de treball, e-CAP, en els centres d'atenció primària del servei d'atenció primària de la població de l’Hospitalet del Llobregat. La solució desenvolupada és una aplicació Web que proporciona la funcionalitat requerida per a dur a terme el control de l'equip informàtic, així com la gestió de les incidències. Aquesta aplicació Web està enfocada al personal d'atenció a l'usuari dels centres anomenats anteriorment amb la supervisió del departament de Sistemes d'Informació de cada servei d'atenció primària.
