ECG study in practical labs for biomedical engineering training

Non-invasive biomedical measurements are one of the most important technological contributions whitin the biomedical engineering field. On this paper, a dual laboratory session student oriented is designed to simulate and implement a cardial signal monitor. During the first session, ORCAD PSpice software is used to simulate the whole process. The students can acquire knowledge on the process by configuring and running both the instrumentation amplifier and a passive filter to improve the signal quality. The second session requires from the student basic laboratory skills to use a specific printed circuit board (PCB) to measure its very own cardiac potential. As a result, from this session, the student can visualize the ECG signal acquired directly on the laboratory oscilloscope

New trends in ICT regarding education

In the 21st century and because of the exponential growth of the Internet and Information Communication Technologies (ICT), people lived in a technological age, in all areas and in all contexts, we have daily contact with technology, with access to information, linked to it, we have a constant update of technological services and tools that change the method we study, work, communicate and socialize on an unprecedented scale. These constant changes oblige everyone regardless the age, gender or profession to possess a range of functional and critical thinking skills, such as Information Literacy, Media Literacy and Technology Literacy. This evolution, forces, the promoters of education, to be always aware of changes that society is introducing outside of the classroom. Today students don’t have the same role that used to, independently of age, they are very active and no longer the same introverted child that studied a few years ago in the classrooms. Also the educational environments can be created anywhere and used everywhere. According to this, students are used to seeking different forms and ways of motivation in and out of the classroom, they need that the learning and teaching process move along with the society and ICT changes. In order to ensure the success of today’s students, it’s important to give them the technological skills to make the correct use of ICT, to perform essential tasks for their training such as research and information selection, problems solvers and decision makers, creative and effective users of productivity tools and communicators, collaborators, publishers and producers of contents. The main purpose of this communication is, to show a part of ICT tools that can be used in educational settings to support learners, helping them to develop key skills in their training process, it’s also relevant to show how these tools can help teachers to achieve these objectives on the daily activities.No século XXI e por causa do crescimento exponencial da Internet e das Tecnologias de Comunicação da Informação (TIC), as pessoas vivem numa era tecnológica, em todas as áreas e em todos os contextos. Temos contacto diário com tecnologia, com acesso à informação e associado a este fenómeno existe uma constante atualização de serviços tecnológicos e ferramentas que mudam os métodos de estudo, trabalho, comunicação e socialização numa escala sem precedentes. Essas mudanças constantes obrigam a todos, independentemente da idade, sexo ou profissão, a possuir uma gama de habilidades de pensamento funcional e crítico, como literacia para a informação, literacia para os media e literacia tecnológica. Essa evolução, força os responsáveis da educação, a estarem sempre conscientes das mudanças que a sociedade está introduzindo fora da sala de aula. Hoje, os alunos não têm o mesmo papel que há uns anos atrás. As crianças são muito ativas, não revelando os comportamentos introvertidos que anteriormente evidenciavam. Além disso, os ambientes educacionais podem ser criados em qualquer lugar e usados em todo o lado. Os alunos estão habituados a procurar diferentes formas de motivação dentro e fora da sala de aula, eles precisam que o processo de ensino-aprendizagem acompanhe as mudanças da sociedade e das TIC. A fim de garantir o sucesso dos estudantes de hoje, é importante dar-lhes as habilidades tecnológicas para fazer o uso correto das TIC, para executar tarefas essenciais para sua formação, como a pesquisa e seleção de informações, aprender a solucionar problemas e a tomar decisões a ser utilizadores efetivos das ferramentas de produtividade, comunicação e colaboração, bem como serem editores e produtores de conteúdos. O principal objetivo desta comunicação é mostrar uma parte das ferramentas de TIC que podem ser usadas em ambientes educacionais para apoiar os alunos, ajudando-os a desenvolver habilidades-chave no seu processo formativo. Pretendemos também mostrar como é que essas ferramentas podem ajudar os professores a alcançar os objetivos pedagógicos nas atividades diárias

Design Within Complex Environments: Collaborative Engineering in the Aerospace Industry

The design and the industrialization of an aircraft, a major component, or an aerostructure is a complex process. An aircraft like the Airbus A400M is composed of about 700,000 parts (excluding standard parts). The parts are assembled into aerostructures and major components, which are designed and manufactured in several countries all over the world. The introduction of new Product Lifecycle Management (PLM) methodologies, procedures and tools, and the need to reduce time-to-market, led Airbus Military to pursue new working methods to deal with complexity. Collaborative Engineering promotes teamwork to develop product, processes and resources from the conceptual phase to the start of the serial production. This paper introduces the main concepts of Collaborative Engineering as a new methodology, procedures and tools to design and develop an aircraft, as Airbus Military is implementing. To make a Proof of Concept (PoC), a pilot project, CALIPSOneo, was launched to support the functional and industrial design process of a medium size aerostructure. The aim is to implement the industrial Digital Mock-Up (iDMU) concept and its exploitation to create shop fl oor documentation

The Caterpillar Gallery: Quadric Surface Theorems, Parametric Design and Digital Fabrication

The use of certain quadratic surface theorems has mainly been associated in architecture with the design of classical vaults, domes and piping. The work presented by the authors is intended to explore the potential of these theorems to be used in the generation law for more complex shapes in contemporary architecture. The paper shows the case study of a built full-scale prototype, The Caterpillar gallery, a project stemming from the combination of geometric research and teaching innovation. Formal and structural experimentation take place in this project where, by starting from geometrical considerations, an efficient way of generating longitudinal spaces is proposed. One of the mentioned theorems applied to rotational cones provides the starting point for the generation of a set of concatenated surfaces that, once assembled, constitute a very stable self-supporting structure with a variety of possible applications

The effectiveness of the international strategy in the analysis of the political language: Berlusconi´s speech at the chamber of deputies on the 13TH May 2008

In this context we will oversee to understand if and in which measure, the intentional attitude delineated today by the school of Anglo-Saxon thought and, in particular, by Dennett’s philosophy, can constitute an opportune and effective instrument for the analysis of the public language. With the expression “intentional system” we refer to the addressee of the communicative enterprise: a collectivity of people joined by the sharing a physical space and a temporal time; such a system can be explained, rationalized and, possibly, anticipated (as for its actions and to its behaviors) through the attribution to it of shared convictions and desires, which constitute the common sense of that organism. The so delineated philosophy of intentionality becomes, in this within, hermeneutics of the speech held by the then Prime Minister Silvio Berlusconi to the Chamber of Deputies on May, 13 2008, that is in occasion of the beginning of its IV legislature. The exposure of the former prime Minister insisted, in order to guarantee to his own government the necessary consent, on the baggage of convictions and desires shared by the Italians, in an historical moment of confusion and political-institutional instability. That speech evidenced proper values of the cultural and ideological matrix of Italy: the house, the family, the entrepreneurial increase of North, the elimination of the organized crime in the South, the tax reduction on the job of the entrepreneurs, individual safety, the removal of the material causes of the abortion. Such concepts were introduced in order to attract the interest of a conservative public opinion and to diverge the attention from the substance of that government’s action, that realized itself in a plan of drastic reduction of the job in Public Administration and of increase of the tax charge, in the picture of a progressive and general economic recess
