Internet Geography: New Spaces of Information

The objective of great investments in telecommunication networks is to approach economies and put an end to the asymmetries. The most isolated regions could be the beneficiaries of this new technological investments wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services or products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical and real space, location is defined by two or three geographical co-ordinates. In the network virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. The Internet Geography, Cybergeography or Geography of Cyberspace are only three examples. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to Internet dissemination and regional development studies. The Portuguese territory is seen in a completely new form: the IP address distribution of Country Code Top Level Domains (.pt) could show new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to reflect the info-structural dynamic and economic development of a territory, especially at regional level.

Internet Geography: Spaces of Innovation

Information Society plays an important role in all kinds of human activity, inducing new forms of economic and social organization and creating knowledge. Over the last twenty years of the 20th century, large investments in telecommunication networks were made to approach economies and put an end to the asymmetries. The most isolated regions were the beneficiaries of this new technological investment’s wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services, products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical/real space, location is defined by two or three geographical co-ordinates. In the network/virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. Internet Geography is one example. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to regional development studies, and at the same time. The IP address distribution of Country Code Top Level Domains (.pt for Portugal) could show the same economic patterns, reflecting territorial inflexibility or, by opposition, new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to analyse the info-structural dynamic and economic development of a territory, especially at regional level. At the same time it shows that information technologies are essential to innovation and competitive advantage.

Augmenting spaces and creating interactive experiences using video camera networks

This research addresses the problem of creating interactive experiences to encourage people to explore spaces. Besides the obvious spaces to visit, such as museums or art galleries, spaces that people visit can be, for example, a supermarket or a restaurant. As technology evolves, people become more demanding in the way they use it and expect better forms of interaction with the space that surrounds them. Interaction with the space allows information to be transmitted to the visitors in a friendly way, leading visitors to explore it and gain knowledge. Systems to provide better experiences while exploring spaces demand hardware and software that is not in the reach of every space owner either because of the cost or inconvenience of the installation, that can damage artefacts or the space environment. We propose a system adaptable to the spaces, that uses a video camera network and a wi-fi network present at the space (or that can be installed) to provide means to support interactive experiences using the visitor’s mobile device. The system is composed of an infrastructure (called vuSpot), a language grammar used to describe interactions at a space (called XploreDescription), a visual tool used to design interactive experiences (called XploreBuilder) and a tool used to create interactive experiences (called urSpace). By using XploreBuilder, a tool built of top of vuSpot, a user with little or no experience in programming can define a space and design interactive experiences. This tool generates a description of the space and of the interactions at that space (that complies with the XploreDescription grammar). These descriptions can be given to urSpace, another tool built of top of vuSpot, that creates the interactive experience application. With this system we explore new forms of interaction and use mobile devices and pico projectors to deliver additional information to the users leading to the creation of interactive experiences. The several components are presented as well as the results of the respective user tests, which were positive. The design and implementation becomes cheaper, faster, more flexible and, since it does not depend on the knowledge of a programming language, accessible for the general public.

Geography of the Information Society

All every day activities take place in space. And it is upon this that all information and knowledge revolve. The latter are the key elements in the organisation of territories. Their creation, use and distribution should therefore occur in a balanced way throughout the whole territory in order to allow all individuals to participate in an egalitarian society, in which the flow of knowledge can take precedence over the flow of interests. The information society depends, to a large extent, on the technological capacity to disseminate information and, consequently, the knowledge throughout territory, thereby creating conditions which allow a more balanced development, from the both the social and economic points of view thus avoiding the existence of info-exclusion territories. Internet should therefore be considered more than a mere technology, given that its importance goes well beyond the frontiers of culture and society. It is already a part of daily life and of the new forms of thinking and transmitting information, thus making it a basic necessity essential, for a full socio-economic development. Its role as a platform of creation and distribution of content is regarded as an indispensable element for education in today’s society, since it makes information a much more easily acquired benefit.”…in the same way that the new technologies of generation and distribution of energy allowed factories and large companies to establish themselves as the organisational bases of industrial society, so the internet today constitutes the technological base of the organisational form that characterises the Information Era: the network” (CASTELLS, 2004:15). The changes taking place today in regional and urban structures are increasingly more evident due to a combination of factors such as faster means of transport, more efficient telecommunications and other cheaper and more advanced technologies of information and knowledge. Although their impact on society is obvious, society itself also has a strong influence on the evolution of these technologies. And although physical distance has lost much of the responsibility it had towards explaining particular phenomena of the economy and of society, other aspects such as telecommunications, new forms of mobility, the networks of innovation, the internet, cyberspace, etc., have become more important, and are the subject of study and profound analysis. The science of geographical information, allows, in a much more rigorous way, the analysis of problems thus integrating in a much more balanced way, the concepts of place, of space and of time. Among the traditional disciplines that have already found their place in this process of research and analysis, we can give special attention to a geography of new spaces, which, while not being a geography of ‘innovation’, nor of the ‘Internet’, nor even ‘virtual’, which can be defined as one of the ‘Information Society’, encompassing not only the technological aspects but also including a socio-economic approach. According to the last European statistical data, Portugal shows a deficit in terms of information and knowledge dissemination among its European partners. Some of the causes are very well identified - low levels of scholarship, weak investments on innovation and R&D (both private and public sector) - but others seem to be hidden behind socio-economical and technological factors. So, the justification of Portugal as the case study appeared naturally, on a difficult quest to find the major causes to territorial asymmetries. The substantial amount of data needed for this work was very difficult to obtain and for the islands of Madeira and Azores was insufficient, so only Continental Portugal was considered for this study. In an effort to understand the various aspects of the Geography of the Information Society and bearing in mind the increasing generalised use of information technologies together with the range of technologies available for the dissemination of information, it is important to: (i) Reflect on the geography of the new socio-technological spaces. (ii) Evaluate the potential for the dissemination of information and knowledge through the selection of variables that allow us to determine the dynamic of a given territory or region; (iii) Define a Geography of the Information Society in Continental Portugal.

MASS CONSERVATION ENHANCEMENT OF FREE BOUNDARY FLOWS IN COMPOSITES MANUFACTURING

Undesirable void formation during the injection phase of the liquid composite molding process can be understood as a consequence of the non-uniformity of the flow front progression, caused by the dual porosity of the fiber perform. Therefore the best examination of the void formation physics can be provided by a mesolevel analysis, where the characteristic dimension is given by the fiber tow diameter. In mesolevel analysis, liquid impregnation along two different scales; inside fiber tows and within the spaces between them; must be considered and the coupling between these flow regimes must be addressed. In such case, it is extremely important to account correctly for the surface tension effects, which can be modeled as capillary pressure applied at the flow front. When continues Galerkin method is used, exploiting elements with velocity components and pressure as nodal variables, strong numerical implementation of such boundary conditions leads to ill-posing of the problem, in terms of the weak classical as well as stabilized formulation. As a consequence, there is an error in mass conservation accumulated especially along the free flow front. This article presents a numerical procedure, which was formulated and implemented in the existing Free Boundary Program in order to significantly reduce this error.

Mass Conservation Enhancement of Free Boundary Mesolevel Flows during LCM Processes of Composites Manufacturing

Undesirable void formation during the injection phase of the liquid composite moulding process can be understood as a consequence of the non-uniformity of the flow front progression, caused by the dual porosity of the fibre perform. Therefore the best examination of the void formation physics can be provided by a mesolevel analysis, where the characteristic dimension is given by the fibre tow diameter. In mesolevel analysis, liquid impregnation along two different scales; inside fibre tows and within the open spaces between them; must be considered and the coupling between these flow regimes must be addressed. In such case, it is extremely important to account correctly for the surface tension effects, which can be modelled as capillary pressure applied at the flow front. Numerical implementation of such boundary conditions leads to ill-posing of the problem, in terms of the weak classical as well as stabilized formulation.

Numerical Method to Predict Void Formation during The Liquid Composite Molding Process

Void formation during the injection phase of the liquid composite molding process can be explained as a consequence of the non-uniformity of the flow front progression. This is due to the dual porosity within the fiber perform (spacing between the fiber tows is much larger than between the fibers within in a tow) and therefore the best explanation can be provided by a mesolevel analysis, where the characteristic dimension is given by the fiber tow diameter of the order of millimeters. In mesolevel analysis, liquid impregnation along two different scales; inside fiber tows and within the open spaces between the fiber tows must be considered and the coupling between the flow regimes must be addressed. In such cases, it is extremely important to account correctly for the surface tension effects, which can be modeled as capillary pressure applied at the flow front. Numerical implementation of such boundary conditions leads to illposing of the problem, in terms of the weak classical as well as stabilized formulation. As a consequence, there is an error in mass conservation accumulated especially along the free flow front.

Os reais hospitais militares em Portugal administrados e fundados pelos Irmãos Hospitaleiros de S. João de Deus 1640-1834

RESUMO: Desde 1640 até data extrema de 1834, os Irmãos Hospitaleiros de S. João de Deus foram os responsáveis, directa e indirectamente, pela administração e corpo de enfermagem dos Reais Hospitais Militares em Portugal, actividades que analisamos ao longo dos séculos, desenvolvendo pressupostos temáticos relativamente a sua actuação no tempo e no espaço. É durante o séc. XVII até ao séc. XIX, que vemos os cuidados da corte para com a assistência aos soldados enfermos e doentes, ao publicar inúmera legislação relativamente à complexidade assistencial na área militar, a qual foi por nós compilada para melhor contextualização da importância dos Hospitais Militares em Portugal. Os Regimentos, os Alvarás, os Regulamentos e as Ordens do Dia, constituem um objecto fundamental de pesquisa e análise para caracterizar o quotidiano nesses mesmos locais. Os Hospitais Militares desde a sua fundação, dos primórdios das Guerras da Aclamação em 1640, até ao advento do liberalismo em 1834, eram centros de conhecimento técnico e científico com um corpo assistencial especializado, onde um conjunto pluridisciplinar de profissionais zelava qualitativamente pelos assistidos, e onde os Irmãos Hospitaleiros de S. João de Deus desempenhavam funções de administradores, enfermeiros e capelães. Nesse sentido elaboramos uma listagem cronológica para inter relacionar os Irmãos Hospitaleiros e os Hospitais Militares, pois é impossível separar a Ordem de S. João de Deus da componente assistencial aos enfermos e doentes militares em Portugal. A importância urbana e arquitectónica, que os Reais Hospitais Militares tiveram no contexto orgânico e defensivo nas Praças de Guerra, é realçado pela forma como estes se encontravam implantados e construídos, demarcando-se esteticamente da globalidade edificada, pois constituíam parte integrante dos equipamentos militares, como era teorizado pelos técnicos militares. Assim analisamos a localização dos imóveis, para além do próprio edifício hospitalar, com o meio, ou seja com a urbanidade das Praças de guerra. A sobriedade arquitectónica dos Hospitais Militares, integrada nos grandes ciclos das correntes culturais europeia e nacional, associada à riqueza decorativa e iconoclasta desenvolvida nesses locais, dá-nos uma dimensão da importância científica que esses núcleos assistenciais tiveram, contribuindo para a difusão do culto e circulação da imaginária de S. João de Deus em Portugal e dos Santos venerados nos Hospitais Militares. Desta forma compreendemos o alicerçar devocional que o reino tinha por este Santo, como o fundador do conceito assistencial do hospital moderno. Estando intrinsecamente ligado a este facto vemos o proliferar do culto e da imaginária de S. João de Deus em Portugal, centrando-se a iconografia artística do Santo em torno das localidades onde se enraizaram os Hospitais Militares. Hoje, nos imóveis hospitalares, não é difícil analisar uma lenta evolução da funcionalidade dos seus espaços, gravitando o desenvolvimento estrutural assistencial em torno das enfermarias e salas de cirurgia, mantendo-se perene este arquétipo arquitectónico desde o séc. XVII até meados do séc. XIX, as quais foram levantadas, comparadas e analisadas. Foi com a exclaustração das Ordens Religiosas, pelo Decreto de 29 de Maio de 1834, que acabou a extraordinária e valorosa acção administrativa, tutelar e corpo de enfermagem dos Irmãos Hospitaleiros de S. João de Deus, na área específica da assistência militar em Portugal, extinguindo-se, nalguns casos, os Hospitais Militares, pois o reino não estava preparado para substituir esses profissionais de saúde. O nosso estudo desenvolve-se por cerca de 295 anos, espaço temporal em que os Hospitais Militares foram administrados e fundados pelos Irmãos de S. João de Deus em Portugal.---------ABSTRACT: Since 1640 until 1834 the Hospitaller Brothers of S. John of God were the responsibles, direct and indirectly, for the administration and nursing body of the Royal Military Hospitals in Portugal, activities that we analyse throughout the centuries, developing thematic presuppositions regarding its performance in time and in space. It is during the 17th century until the 19th century, that we see the court’s care with the assistance of the wounded and sick by the publishing of much legislation regarding the assistance complexity in the military area, which was compiled by us in order to achieve a better comprehension of the importance of the Military Hospitals in Portugal. The Regiments, Charters, Regulations and Orders of Day constitute a fundamental object of research and analysis to characterise the quotidian of these locations. The Military Hospitals, since its foundation, in the beginning of the Wars of Acclamation in 1640, until the advent of liberalism in 1834, were centres of technical and scientific knowledge with a specialized assistance body, were a multidisciplinary set of professionals took qualitatively care of the attended, and where the Hospitaller Brothers of S. John of God performed the tasks of administrators, nurses and chaplains. In this perspective, we created a chronological listing in order to relate the Hospitaller Brothers with the Military Hospitals, since it is impossible to separate the Hospitaller Order of S. John of God from the component of assistance to the military sick and wounded in Portugal. The urban and architectural importance that the Royal Military Hospitals had in the organic and defensive context of the War Fortifications is emphasized by the way these were implanted and built and by its architectural demarcation of the edified whole, since they constituted an integrant part of the military equipments, as it was theorized for the military architecture. Therefore we analyse the location of the real estate, analysing not only the hospital building itself, but also its relation with the environment, i. e. with the urbanism of the war fortifications. The architectural sobriety of Military Hospitals, integrated in the big cycles of cultural streams in Europe and Portugal, associated to the decorative and iconoclastic wealth developed in these locations, give us a dimension of the scientific importance that these hospitals had, contributing to the diffusion of the cult and circulation of sculptures and paintings of S. John of God in Portugal and of the Saints revered in the Hospitals. In this way, we understand the consolidation of the devotion that the kingdom had for this Saint, the founder of the assistance concept of the modern hospital. The proliferation of the cult and iconography of S. John of God is intrinsically connected to this fact, the artistic iconography concentrating itself around the localities were the Military Hospitals were built. Today, in the assistance buildings, it is not difficult to analyse a slow evolution of the functionality of its spaces, gravitating the structural assistance development around the infirmaries and surgery rooms, this architectural archetype being perennial from the 17th century until the middle of the 19th century. These infirmaries were pointed out, compared and analysed. It was the expulsion of the Religious Orders, by the Decree of May 29th 1834, that ended with the extraordinary and valorous administrative and tutelary action and nursing body of the Hospitaller Brothers of S. John of God, in the specific area of military assistance in Portugal, extinguishing, in some cases, the Military Hospitals, since the kingdom wasn’t prepared to substitute these health professionals. Our study is developed in a timeframe of 295 years, period in which the Military Hospitals were administrated and founded by the Brothers of S. John of God in Portugal.
