Aplicación web para la ejecución de tareas de anàlisis SIG remotas (WPS)

El siguiente proyecto trata sobre el desarrollo de una aplicación web que ejecuta funciones de análisis sig remotas (WPS) a partir de una plataforma de software libre de servicio de aplicaciones geoespaciales (Open Geo Suite). Se centrará en la creación de un plugin que consiga hacer varias intersecciones entre dos capas de información geoespacial. El entorno visual de la aplicación SIG está basado en un modelo visual predefinido para un navegador web a partir del SDK para la generación propia de aplicaciones de OpenGeo Suite 3. 02 para Windows. La tecnología utilizada para la implementación de este proyecto ha sido la plataforma OpenGeo Suite que incluye la librería OpenLayers para javascript y Geoserver como servidor para la gestión de información geoespacial y Apache Ant (instalado posteriormente) para el correcto funcionamiento del SDK. Como ejemplo para mostrar el resultado de esta aplicación se han escogido dos capas de información geospacial: country.shp (países europeos) y mjurban.shp (ciudades europeas)

Avaliação da qualidade de sítios web institucionais: aplicação de métrica às faculdades de medicina do espaço ibérico

Este trabalho visou o desenvolvimento de uma métrica e a sua aplicação na avaliação da qualidade dos sítios web das Faculdades de Medicina Ibéricas, estruturada nas características de alto nível da norma ISO-9126 que interessam aos utilizadores. A aplicação da métrica mostrou-se um processo simples, e a análise comparativa entre as Faculdades Portuguesas e Espanholas, mostrou que, globalmente, não existem diferenças significativas na qualidade dos seus sítios web. This study aimed to develop a metric and its application in assessing the quality of the websites from Iberian medicine schools, structured on the characteristics of high-level ISO-9126 standard that interest to the users. The metric implementation proved to be a simple process, and comparative analysis between the Portuguese and Spanish Schools, showed that, overall, there are no significant differences in the quality of their websites

Deliverable DJRA1.2. Solutions and protocols proposal for the network control, management and monitoring in a virtualized network context

This deliverable presents several research proposals for the FEDERICA network, in different subjects, such as monitoring, routing, signalling, resource discovery, and isolation. For each topic one or more possible solutions are elaborated, explaining the background, functioning and the implications of the proposed solutions.This deliverable goes further on the research aspects within FEDERICA. First of all the architecture of the control plane for the FEDERICA infrastructure will be defined. Several possibilities could be implemented, using the basic FEDERICA infrastructure as a starting point. The focus on this document is the intra-domain aspects of the control plane and their properties. Also some inter-domain aspects are addressed. The main objective of this deliverable is to lay great stress on creating and implementing the prototype/tool for the FEDERICA slice-oriented control system using the appropriate framework. This deliverable goes deeply into the definition of the containers between entities and their syntax, preparing this tool for the future implementation of any kind of algorithm related to the control plane, for both to apply UPB policies or to configure it by hand. We opt for an open solution despite the real time limitations that we could have (for instance, opening web services connexions or applying fast recovering mechanisms). The application being developed is the central element in the control plane, and additional features must be added to this application. This control plane, from the functionality point of view, is composed by several procedures that provide a reliable application and that include some mechanisms or algorithms to be able to discover and assign resources to the user. To achieve this, several topics must be researched in order to propose new protocols for the virtual infrastructure. The topics and necessary features covered in this document include resource discovery, resource allocation, signalling, routing, isolation and monitoring. All these topics must be researched in order to find a good solution for the FEDERICA network. Some of these algorithms have started to be analyzed and will be expanded in the next deliverable. Current standardization and existing solutions have been investigated in order to find a good solution for FEDERICA. Resource discovery is an important issue within the FEDERICA network, as manual resource discovery is no option, due to scalability requirement. Furthermore, no standardization exists, so knowledge must be obtained from related work. Ideally, the proposed solutions for these topics should not only be adequate specifically for this infrastructure, but could also be applied to other virtualized networks.Postprint (published version

Ludic behavior among children of Brazil's northeast region: categorization of playful activities

Este artigo visa categorizar as brincadeiras das crianças de um povoado rural do nordeste do Brasil. Foram observadas individualmente 32 crianças entre dois e 12 anos, de ambos os sexos, brincando em ambiente livre, em sessões de cinco minutos. A categoria de 'brincadeiras simbólicas' foi a mais observada (49%). Os temas das brincadeiras simbólicas estavam predominantemente atrelados ao modo de vida local. Diferenças de gênero foram observadas e analisadas. Os dados sugerem que meninas brincam mais simbolicamente, enquanto as brincadeiras dos meninos são mais variadas. A relação entre brincadeira e contexto baseia-se no aproveitamento das potencialidades que o ambiente oferece para o desenvolvimento da criança caracterizando as relações entre aspectos particulares de cada ambiente e as atividades lúdicas desenvolvidas.This paper aims to categorize the most frequent playful activities in a sample of children from a rural community of Brazil's northeast region. Thirty two children of both sexes, aged 2-12 years, were individually observed during free play, in five minutes sessions each. The most observed category of play was 'symbolic games' (49%). The themes of the symbolic games were predominantly tied with the local way of living. Gender differences were observed and analyzed. The collected data suggest that female plays tend to be symbolic, while male plays tend to be more varied. It was observed that the relation between playful activities and local context is based upon the employment of resources that the specific environment offers to the child's development, characterizing the relations between particular contexts and the ludic activities developed in it

EVALUATION OF THE CLUSTERING PERFORMANCE OF AFFINITY PROPAGATION ALGORITHM CONSIDERING THE INFLUENCE OF PREFERENCE PARAMETER AND DAMPING FACTOR

The identification of significant underlying data patterns such as image composition and spatial arrangements is fundamental in remote sensing tasks. Therefore, the development of an effective approach for information extraction is crucial to achieve this goal. Affinity propagation (AP) algorithm is a novel powerful technique with the ability of handling with unusual data, containing both categorical and numerical attributes. However, AP has some limitations related to the choice of initial preference parameter, occurrence of oscillations and processing of large data sets. This paper evaluates the clustering performance of AP algorithm taking into account the influence of preference parameter and damping factor. The study was conducted considering the AP algorithm, the adaptive AP and partition AP. According to the experiments, the choice of preference and damping greatly influences on the quality and the final number of clusters
