This paper develops an energy management system with integration of smart meters for electricity consumers in a smart grid context. The integration of two types of smart meters (SM) are developed: (i) consumer owned SM and (ii) distributor owned SM. The consumer owned SM runs over a wireless platform - ZigBee protocol and the distributor owned SM uses the wired environment - ModBus protocol. The SM are connected to a SCADA system (Supervisory Control And Data Acquisition) that supervises a network of Programmable Logic Controllers (PLC). The SCADA system/PLC network integrates different types of information coming from several technologies present in modern buildings. The developed control strategy implements a hierarchical cascade controller where inner loops are performed by local PLCs, and the outer loop is managed by a centralized SCADA system, which interacts with the entire local PLC network. In order to implement advanced controllers, a communication channel was developed to allow the communication between the SCADA system and the MATLAB software. (C) 2014 The Authors.

Num contexto de mudana a nvel de hbitos sociais em que impera a necessidade de comunicar de uma forma mais natural e instantnea quanto possvel, o cada vez mais informado e exigente consumidor tem vindo a adquirir um papel mais participativo na comunicao e construo das marcas. Se outrora assistamos passivamente a uma comunicao unidirecional e desprovida de interactividade, hoje impera a possibilidade de podermos manipular ou construir contedos de acordo com as nossas necessidades e preferncias individuais. Neste contexto, a comunicao nos novos meios tecnolgicos tem procurado responder disperso de ateno por parte do consumidor, que se socorre simultaneamente de diversos ecrs. Porm, no ecr em que o novo consumidor mais despende o seu tempo, e com o qual ainda se sente mais vontade, a televiso, a comunicao interactiva ainda se encontra pouca explorada. Para os profissionais de publicidade, e sobretudo para os anunciantes, o conceito de publicidade interactiva, quando inserida no meio televisivo, deveras recente, carecendo de um maior aprofundamento terico e emprico. Tendo em vista este aprofundamento, o objectivo geral deste trabalho consiste na caracterizao do panorama da publicidade interactiva na televiso em Portugal tendo como termo de comparao o estrangeiro. A dissertao assumiu a forma de um estudo exploratrio e misto sequencial, desenvolvido com base na anlise de contedo de um conjunto de casos nacionais de Publicidade Interactiva na Televiso fornecidos pelo MEO e de casos estrangeiros publicados na Internet. Assentando a anlise numa grelha prpria, procurou caracterizar-se o panorama actual da Publicidade Interactiva na Televiso nacional tendo como termo de comparao o que se passa l fora, do ponto de vista dos contedos, da partilha destes, da dependncia de um second screen e dos objectivos subjacentes aos anncios. Foi possvel concluir com este estudo que, apesar de a Publicidade Interactiva na Televiso se encontrar mais desenvolvida no estrangeiro, em Portugal observaram-se caractersticas singulares e positivas, o que aponta que nos encontramos a evoluir a passos largos para alcanar melhores experincias interactivas.

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to save events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations memory.

Outlining the best strategies for seismic risk mitigation requires that both benefits and costs of retrofitting are known in advance. The assessment of the vulnerability of building typologies is a first step of a more extensive effort, concerning the analysis of the viability of seismic risk mitigation and taking into account retrofitting costs. The methodology adopted to obtain the seismic vulnerability of some classes of residential buildings existing in mainland Portugal is presented. This methodology is based on a structural analysis of individual buildings belonging to the same typology. An application example is presented to illustrate the methodology. Fragility curves of boxed building typology are also presented and broken down into three height classes: low rise, medium-rise and high-rise. These curves are based on average capacity spectra derived from several individual buildings belonging to the same typology.
