Since creation of the European Communities the number of Member States has gradually increased from the original six to current twenty-eight. Enlargement has become an EU’s flagship external policy, demonstrating the EU’s ability to shape its neighbourhood and to serve as a catalyst of deep and multilayered reforms. The consecutive seven enlargement rounds went in parallel with widespread internal developments, culminating with the creation of the European Union and, most recently, entry into force of the Treaty of Lisbon. As this volume demonstrates, EU criminal law has evolved considerably from its early days under the legal framework laid down by the Treaty of Maastricht to its current post-Lisbon shape. On 1 December 2014, that is with expiry of a five year transitional regime for the jurisdiction of the Court of Justice, Police and Judicial Co-operation in Criminal Matters became a fully fledged EU policy, governed largely by the same modus operandi as other areas of EU competence and with compulsory jurisdiction of the Court of Justice. As EU criminal law developed internally, so did its external dimension, including the role it plays in the enlargement policy. In case of the latter the expiry of the same transitional period has brought to an end a rather anomalous situation whereby the European Union had more enforcement tools before and after accession vis-à-vis its future/new Member States than it could employ against the old ones. This bifurcation, quite rightly, triggered a lot of discussions about double standards used by the European Union in its pre-accession policy. This is exacerbated by the fact that some of those standards are neither defined in EU law, nor pursued vis-à-vis the existing EU’s Member States. The aim of this chapter is to demonstrate that evolution with particular emphasis on the role of EU Criminal Law in the policy currently employed by the European Union vis-à-vis candidate and potential candidate countries of the Western Balkans and to Turkey. Arguably, together with political conditionality, it has become one of the pillars of the enlargement process and, as the examples of accession negotiations with Montenegro and Serbia prove, its role is likely to increase as rapprochement of other candidates and potential candidates progresses to the next stages.

Designing electric installation projects, demands not only academic knowledge, but also other types of knowledge not easily acquired through traditional instructional methodologies. A lot of additional empirical knowledge is missing and so the academic instruction must be completed with different kinds of knowledge, such as real-life practical examples and simulations. On the other hand, the practical knowledge detained by the most experienced designers is not formalized in such a way that is easily transmitted. In order to overcome these difficulties present in the engineers formation, we are developing an Intelligent Tutoring System (ITS), for training and support concerning the development of electrical installation projects to be used by electrical engineers, technicians and students.

A supervisory control and data acquisition (SCADA) system is an integrated platform that incorporates several components and it has been applied in the field of power systems and several engineering applications to monitor, operate and control a lot of processes. In the future electrical networks, SCADA systems are essential for an intelligent management of resources like distributed generation and demand response, implemented in the smart grid context. This paper presents a SCADA system for a typical residential house. The application is implemented on MOVICON™11 software. The main objective is to manage the residential consumption, reducing or curtailing loads to keep the power consumption in or below a specified setpoint, imposed by the costumer and the generation availability.

Although it is always weak between RFID Tag and Terminal in focus of the security, there are no security skills in RFID Tag. Recently there are a lot of studying in order to protect it, but because it has some physical limitation of RFID, that is it should be low electric power and high speed, it is impossible to protect with the skills. At present, the methods of RFID security are using a security server, a security policy and security. One of them the most famous skill is the security module, then they has an authentication skill and an encryption skill. In this paper, we designed and implemented after modification original SEED into 8 Round and 64 bits for Tag.

O texto expressa uma reflexão sobre a obra Triste Fim de Policarmo Quaresma, escrita em 1915, por Lima Barreto, escritor realista, brasileiro. Busca identificar nas narrativas e ações do seu narrador, um homem comum, as revoltas, mas também as esperanças dos homens comuns no recém criado regime republicano. Enfoca ainda que, apesar dos episódios narrados, dos personagens serem construções ficcionais do autor, nos remetem a personagens, diálogos e espaços do Rio de Janeiro que evocam a historia de um regime ditatorial de Floriano Peixoto, no alvorecer da Republica. Nesse regime, mostra o autor, que a insegurança, a insatisfação e o medo tomaram conta da população do Rio de Janeiro no começo do século XX. E Policarpo Quaresma, o personagem narrador da obra, sofrera as injustiças e arbitrariedades da ditadura do Marechal Floriano Peixoto. Diante disso, revela sua dor e plena desolação com a Republica, forma de governo pelo qual lutara e que ajudara a criar. Por fim, o texto procura mostrar que embora a literatura seja tecida com adornos da ficção, ela traduz a sociedade e o tempo no qual ela foi produzida, além de mostrar que o positivismo sustentava a pratica política da Republica brasileira.

This paper aims at analysing the writing of the Portuguese author António Lobo Antunes, considered one of the major writers in European Literature with 26 books published, by focusing on the strategies deployed in his texts of creating micro-narratives within the main frame, and conveying the elements of individual and collective memory, past and present, the self and the others, using various voices and silences. Lobo Antunes incorporates in his writing his background as a psychiatrist at a Mental Hospital in Lisbon, until 1985 (when he decided to commit exclusively to writing), his experience as a doctor in the Portuguese Colonial War battlefield, but also the daily routines of the pre and post 25th of April 1974 (Portuguese Revolution) with subtle and ironic details of the life of the middle and upper class of Lisbon‘s society: from the traumas of the war to the simple story of the janitor, or the couple who struggles to keep their marriage functional, everything serves as material to develop and interweave a complex plot, that a lot of readers find too enwrapped and difficult to follow through. Some excerpts taken from his first three novels and books of Chronicles and his later novel – Ontem não te Vi em Babilónia (2006) – will be put forward to exemplify the complexity of the writing and the main difficulties of the reader, lost in a multitude of narrators‘ voices. Recently, Lobo Antunes has commented on his work stating: What I write can be read in the darkness. This paper aims at throwing some light by unfolding some of the strategies employed to defy new borders in the process of reading.

Um túnel é uma obra subterrânea dimensionada com o objetivo de satisfazer diversas necessidades num mundo onde o planeamento urbano e a gestão de espaços ganha cada vez mais importância. A execução de este género de obras de engenharia pode ter várias finalidades, que podem ir desde a construção/reabilitação de redes de saneamento, abastecimento de água ou gás (túneis de pequeno diâmetro) até à construção/modernização de redes pedonais, rodoviárias ou ferroviárias, galerias mineiras, tuneis para barragens, etc. (túneis de grande diâmetro). As tuneladoras são uma das ferramentas de desmonte mais utilizadas na execução de obras subterrâneas. Existem no mercado vários tipos de máquinas tuneladoras, a sua escolha e dimensionamento depende de diversos fatores que devem ser cuidadosamente analisados, nomeadamente tipo de terreno a escavar, presença ou não de água na zona de escavação, dureza e/ou abrasividade das formações a atravessar, etc. Será feita uma abordagem aos princípios de funcionamento de este tipo de equipamentos, indicando o seu campo de aplicação dentro da respetiva tecnologia de escavação onde se inserem. Finalmente será desenvolvido o caso da empreitada: “Execução da Travessia do Rio Ave, da Estação Elevatória de Vila do Conde e dos Sistemas Elevatória da Aguçadoura e da Apúlia 4 - AR 44.0.08”, onde em alternativa ao desvio provisório do Rio Ave em Vila do Conde foi projetada a execução de duas travessias no diâmetro 1200 mm, uma delas escavadas maioritariamente em terreno aluvionar brando e a outra em terreno rochoso duro e abrasivo com recurso, em ambos casos, à utilização de máquina tuneladora. Através da avaliação do desempenho do equipamento escolhido para execução de este trabalho será estudada a eficiência da utilização deste tipo de equipamento. Com o objetivo de mostrar os custos associados à execução de obras de escavação subterrânea com recurso a utilização de máquinas tuneladoras, será feita uma análise económica e comparativa relativa aos dois casos de obra apresentados.
