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.

A formação de professores para o ensino da Matemática no ensino básico a alunos com deficiência visual

Resumo: Este estudo surge no âmbito do Mestrado em Reabilitação na Especialidade de Deficiência Visual ministrado em conjunto pelas Faculdades de Ciências Médicas e Motricidade Humana. Na dissertação intitulada Formação de Professores para o Ensino da Matemática no Ensino Básico a Alunos com DV foi desenvolvida uma investigação, incidindo sobre a temática atrás referida. Na primeira parte apresenta-se uma revisão de literatura, onde se exploram vários conceitos relevantes como a deficiência visual, o currículo de matemática no Ensino Básico, as adaptações curriculares dos alunos com DV, as tecnologias de apoio e a Formação dos Professores, entre outros. Na segunda parte apresentam-se as fundamentações teóricas que subjazem à escolha da metodologia de investigação e instrumentação bem como a descrição dos procedimentos de investigação. Participaram neste estudo 52 professores de Matemática dos três ciclos do ensino básico, que tinham alunos cegos ou com baixa visão nas suas turmas. Os dados foram recolhidos através de um questionário aplicados aos professores. Na terceira parte apresentam-se alguns resultados desta pesquisa. Relativamente à Formação de Professores, sendo N= 52, no que diz respeito à Deficiência Visual, a maioria dos professores (58%) diz não ter conhecimento da mesma e 40% dos professores diz ter algum conhecimento sobre a deficiência visual. Destes professores, grande parte referiu não considerar suficiente a informação recebida, pelo que concluímos ser pertinente a proposta de cursos versando a formação de professores em Deficiência Visual. Conclui-se também que os professores sentem dificuldades com os materiais e equipamentos disponíveis embora refiram que tivessem tido alguma informação sobre os mesmos.----------------------------------------- ABSTRACT: This study is the subject of the Master Course on the Specialty of Visual impaired given by both the Faculties of Ciências Médicas and Motricidade Humana. In the dissertation, the title of Which is Vocational Training of Teachers for the Mathematies teaching in the Basic Compulsory education to students with Visual impaired inside of the thematic behind referred. In the first part it is presented a literature revision, where some concepts are explored like the visual impaired, the curriculum of mathematics in the Basic Compulsory Education, the curriculum adaptations to the pupils with visual impaired, the technologies of support and the vocational training of the teachers, among others. In the second part we can recognize the theoretical recitals that support the choice of the research methodology and the whole instrumens meedes as well as the description of the research procedures. 52 professors of Mathematics from the three cycles of basic compulsory education participated in this study, they had blind pupils or with low vision in their classes. The data had been collected through a questionnaire applied to the teachers. In the third part, we come to some results of this research. In what concerns the vocational training of the teachers being N= 52, the majority of them (58%) says not to have knowledge of it and 40% of them says that they have some knowledge on the visual impaired. Among, a great part mentioned not having received sufficient information, as we conclude to be pertinent the proposal of courses makina the vocational training of teachers in visual impaired a reality. One also concludes that the teachers have difficulties with the materials and available equipment even though they mention to have had some information about them.

Changing representations and practices in school mathematics: the case of Modern Math in Portugal

The curricular movement known as Modern Mathematics aimed at the transformation of representations and practices in school mathematics. Its study provides us with ways of understanding how these changes came about. The purpose of this paper is to contribute to the understanding of the ways in which representations of school mathematics gradually were influenced by ideas from the Modern Mathematics movement, how these new ideas merged into local educational traditions, and how they were transformed into meaningful practice. This work is centred on the Portuguese context from the middle 1950s to the middle 1960s, and builds on Chervel’s notion of school culture and Gruzinski’s discussion of connected histories.

Georeferencing Road Accidents with Google Earth: Transforming Information into Knowledge for Decision Support

Over the last fifty years mobility practices have changed dramatically, improving the way travel takes place, the time it takes but also on matters like road safety and prevention. High mortality caused by high accident levels has reached untenable levels. But the research into road mortality stayed limited to comparative statistical exercises which go no further than defining accident types. In terms of sharing information and mapping accidents, little progress has been mad, aside from the normal publication of figures, either through simplistic tables or web pages. With considerable technological advances on geographical information technologies, research and development stayed rather static with only a few good examples on dynamic mapping. The use of Global Positioning System (GPS) devices as normal equipments on automobile industry resulted in a more dynamic mobility patterns but also with higher degrees of uncertainty on road traffic. This paper describes a road accident georeferencing project for the Lisbon District involving fatalities and serious injuries during 2007. In the initial phase, individual information summaries were compiled giving information on accidents and its majour characteristics, collected by the security forces: the Public Safety Police Force (Polícia de Segurança Pública - PSP) and the National Guard (Guarda Nacional Republicana - GNR). The Google Earth platform was used to georeference the information in order to inform the public and the authorities of the accident locations, the nature of the location, and the causes and consequences of the accidents. This paper also gives future insights about augmented reality technologies, considered crucial to advances to road safety and prevention studies. At the end, this exercise could be considered a success because of numerous consequences, as for stakeholders who decide what to do but also for the public awareness to the problem of road mortality.
