Portveb.com : um site para programadores e webdesigners

As exigências da sociedade atual obrigam a mudanças tecnológicas cada vez mais rápidas e constantes para satisfazer as necessidades empresariais, especialmente no que concerne à transmissão de informações de forma cada vez mais rápidas, mas sempre mantendo um elevado padrão de qualidade de conteúdos, bem como níveis de segurança elevados para impedir que os mesmos sejam corrompidos. Desde o aparecimento da Internet que a informação circula de forma cada vez mais veloz, em maiores quantidades e alcança cada vez mais pessoas. No entanto, nem todas as pessoas têm acesso a conteúdos de qualidade, sendo nesse ponto que o desenvolvimento do presente trabalho terá importância na respectiva área. O portveb.com é um website que pretende colmatar uma carência de conteúdos de qualidade para especialistas web designers, programadores e optimizadores de motores de busca. A importância do trabalho desenvolvido deve-se à escassez de websites da referida temática, sendo uma oportunidade para explorar a utilização de soluções técnicas como o Bootstrap, HTML, CSS, Javacript, PHP, MYSQL e desenvolver um website cuja funcionalidade não esteja só restrita a computadores pessoais, mas também a plataformas móveis. O desenvolvimento do website portveb.com demonstrou que a utilização das soluções técnicas já referidas foram a melhor opção do que concerne à obtenção de resultados, por assentar em plataformas onde não foi necessário elaborar um design de raíz, sendo que a interacção com bases de dados como PHP e MySQL tornaram o website mais dinâmico. A realização deste trabalho possibilitou ainda a descoberta de potencialidades do website para soluções técnicas futuras que se destinam a aumentar a partilha de conhecimento entre os utilizadores de forma mais prática e eficiente.

Soils of the Jurassic formations in the central Algarve; their occurrence, distribution, genesis and site qualities

In the central Algarve different soils have developed dependent on petrography of the parent material, slope position and recent erosion. The general patterns of occurence and distribution of different soils are described. The age of an eutric Nitosol is estimated and the relation between the soil and the parent material is investigated. Some different soils are described as examples with their chemical and physical properties. The water budget of soils is described in general with considerations concerning ground water recharge and run-off as well as in dependence of climate and of different site conditions.

A high level e-maintenance architecture to support on-site teams

Emergent architectures and paradigms targeting reconfigurable manufacturing systems increasingly rely on intelligent modules to maximize the robustness and responsiveness of modern installations. Although intelligent behaviour significantly minimizes the occurrence of faults and breakdowns it does not exclude them nor can prevent equipment’s normal wear. Adequate maintenance is fundamental to extend equipments’ life cycle. It is of major importance the ability of each intelligent device to take an active role in maintenance support. Further this paradigm shift towards “embedded intelligence”, supported by cross platform technologies, induces relevant organizational and functional changes on local maintenance teams. On the one hand, the possibility of outsourcing maintenance activities, with the warranty of a timely response, through the use of pervasive networking technologies and, on the other hand, the optimization of local maintenance staff are some examples of how IT is changing the scenario in maintenance. The concept of e-maintenance is, in this context, emerging as a new discipline with defined socio-economic challenges. This paper proposes a high level maintenance architecture supporting maintenance teams’ management and offering contextualized operational support. All the functionalities hosted by the architecture are offered to the remaining system as network services. Any intelligent module, implementing the services’ interface, can report diagnostic, prognostic and maintenance recommendations that enable the core of the platform to decide on the best course of action.

Maritime Security in the Gulf of Guinea: Issues and Solutions for the 21st Century

A producer of 5.4 M bbl/d, totalling almost half of the consumption of the entire European Union, the Gulf of Guinea is a fundamental lifeline and maritime link between Europe, the Americas and Africa. Geographically positioned as a staging post for transit originating in Latin America and coupled with its relatively porous borders, the region is also the perfect stepping stone for contraband heading to European shores. While blessed with an enviable wealth of marine and mineral resources, the region is also plagued by an ever-increasing spectre of maritime piracy; accounting for around 30% of incidents in African waters from 2003 to 2011. It is for these reasons that this research centres around the issues of maritime security in the Gulf of Guinea, with a particular focus on the first two decades of the 21st century. This research looks to examine the overall picture of the present state of play in the area, before going on to provide an analysis of potential regional developments in maritime security. This research begins with the analysis of concepts/phenomena that have played a notable role in the shaping of the field of maritime security, namely Globalisation and security issues in the post-Cold War era. The ensuing chapter then focuses in on the Gulf of Guinea and the issues dominating the field of maritime security in the region. The penultimate chapter presents a SWOT analysis, undertaken as part of this research with the aim of correlating opinions from a variety of sectors/professions regarding maritime security in the Gulf of Guinea. The final chapter builds upon the results obtained from the abovementioned SWOT analysis, presenting a series of potential proposals/strategies that can contribute to the field of maritime security in the region over the coming years. This research draws to a close with the presentation of conclusions taken from this particular investigation, as well as a final overview of the earlier presented proposals applicable to the field of maritime security during the second decade of the 21st century.
