Printoo – from here to the Internet of Things
This thesis is a pedagogical case study on Strategy applied to Innovation, using Printoo – a product by Ynvisible – as a setting. Hence, the focus of this case is to describe and analyze the challenge of this company and its managers to define a fit strategy for its new, innovative product.
Printoo’s concept is highly innovative and it is inserted in an area of technological development with great potential – Printed Electronics. Several tools and trends influence this area, such as the Makers culture, Crowdfunding, Open-Source and the increasing use of Technology in Education. Furthermore, there is a debate on implementing the concept of the Internet of Things – in which Printed Electronics may have a role.
From the interviews and analysis performed, this paper has two key conclusions. The first one is that Ynvisible should focus on both Printoo – a series of kits of Printed Electronics technologies components – and on the company’s own proprietary Electrochromic displays – that are included in Printoo – in order to maximize the power it has over the potential profits that will derive from this innovation, because Printoo is highly imitable and the displays are not. Nevertheless, Printoo is an important marketing tool to promote Ynvisible’s displays and other components from suppliers.
The second conclusion is that Education is an important market that Printoo should address, and that the approach should combine continuous improvement – of the technologies that the kits contain and of the experiences they allow to perform – and service improvement – as courses and workshops – which actually Ynvisible is starting to do. Other markets are also important, such as the Makers, Open Source market and the Prototyping market
Capistrano de Abreu (1907): O surgimento de um povo novo: o povo brasileiro
O artigo discute inicialmente alguns dados biográficos de Capistrano de Abreu que contribuíram para a posição inovadora que conquistou na historiografia brasileira; examina as suas relações com Varnhagen e o IHGB, a sua hesitação teórico-metodológica entre o positivismo e o historicismo, o seu novo ponto de vista sobre a história brasileira, que se denominou de "redescoberta do Brasil". Resume e analisa a sua obra "Capítulos de História Colonial" procurando apreender todo o seu alcance metodológico e político e conclui com reflexões sobre a temporalidade histórica do Brasil, segundo a sua perspectiva renovadora, que enfatiza a ruptura com a tradição lusitana e a opção pelo futuro brasileiro.The article initially discusses some of Capistrano de Abreu's biographical data that have contributed to the innovative position he has achieved in the Brazilian historiography. It also examines his relationship with Varnhagen and the IHGB, his theoretical-methodological hesitation between positivism and historicism, and his new point of view on the Brazilian history wich was called "rediscovery of Brazil". It summarizes and analyses his work "Capítulos de História Colonial" (Chapters of Colonial History), trying to apprehend its methodological and political attainment and concludes with reflections on the historical temporality of Brazil, according to his innovative perspective, that enphasizes the rupture of the Lusitanian tradition and the option for a Brazilian future
História da História (1950/60). História e Estruturalismo: Braudel versus Lévi-Strauss
oai:ojs.emnuvens.com.br:article/1The aim of this article is retakes and reflects about the intense debate between Ethonology and History in the 1950/60 decades about the historical knowledge. The Levi-straussianne Ethnology has obliged the History to put some questions about the articulations between event and structure, newness and repetition, conscience and inconscient, singular and universal, sinchrony and diachrony. The answer of the Annales historians was donne by Fernand Braudel.O objetivo deste artigo é retomar e refletir sobre o intenso debate entre Antropologia e História nas décadas de 1950/60 sobre o conhecimento histórico. A Antropologia Levi-Straussiana obrigou a história a se colocar algumas questões sobre as articulações entre evento e estrutura, novidade e repetição, consciência e inconsciente, singular e universal, sincronia e diacronia. A resposta dos historiadores dos Annales foi dadapor Fernand Braudel
A ''crítica histórica da razão": Dilthey versus Kant
Discute-se o duplo objetivo da Introdução à s ciências do espírito, de Dilthey: um ”” kantiano - de realizar uma crítica da razão histórica; outro ”” anti-kantiano ”” de uma crítica histórica da razão. Dilthey entende dever superar a distinção rígida, estabelecida por Kant, entre o homem-natureza e o homem-história
Authenticated file broadcast protocol
The File Broadcast Protocol (FBP) was developed as a part of the DETIboot system. DETIboot allows a host to broadcast an operating system image through an 802.11 wireless network to an arbitrary number of receivers. Receivers can load the image and immediately boot a Linux live session. The initial version of FBP had no security mechanisms. In this paper we present an authentication protocol developed for FBP that ensures a correct file distribution from the intended source to the receivers. The performance valuations have shown that, with the best operational configuration tested, the file download time is increased by less than 5%
Sistema de fabrico rápido de implantes ortopédicos
Este estudo teve como objectivo o desenvolvimento uma metodologia
de fabrico rápido de implantes ortopédicos, em simultaneidade
com a intervenção cirúrgica, considerando duas
potenciais aplicações na área ortopédica: o fabrico de implantes
anatomicamente adaptados e o fabrico de implantes para substituição
de perdas ósseas. A inovação do trabalho desenvolvido
consiste na obtenção in situ da geometria do implante, através
da impressão directa de um material elastomérico (polivinilsiloxano)
que permite obter com grande exactidão a geometria
pretendida. Após digitalização do modelo obtido em material
elastomérico, o implante final é fabricado por maquinagem recorrendo
a um sistema de CAD/CAM dedicado. O implante
após esterilização, pode ser colocado no paciente. O conceito
foi desenvolvido com recurso a tecnologias disponíveis comercialmente
e de baixo custo. O mesmo foi testado sob a forma
de uma artroplastia da anca realizada in vivo numa ovelha. O
acréscimo de tempo de cirurgia foi de 80 minutos sendo 40
directamente resultantes do processo de fabrico do implante.
O sistema desenvolvido revelou-se eficiente no alcance dos
objectivos propostos, possibilitando o fabrico de um implante
durante um período de tempo perfeitamente compatível com o
tempo de cirurgia.This study, aimed the development of a methodology for rapid
manufacture of orthopedic implants simultaneously with the
surgical intervention, considering two potential applications
in the fields of orthopedics: the manufacture of anatomically
adapted implants and implants for bone loss replacement. This
work innovation consists on the capitation of the in situ geometry
of the implant by direct capture of the shape using an elastomeric
material (polyvinylsiloxane) which allows fine detail
and great accuracy of the geometry. After scanning the elastomeric
specimen, the implant is obtained by machining using a
CNC milling machine programmed with a dedicated CAD/CAM
system. After sterilization, the implant is able to be placed on
the patient. The concept was developed using low cost technology
and commercially available. The system has been tested in
an in vivo hip arthroplasty performed on a sheep. The time increase
of surgery was 80 minutes being 40 minutes the time of
implant manufacturing. The system developed has been tested
and the goals defined of the study achieved enabling the rapid
manufacture of an implant in a time period compatible with the
surgery time
Remote sensing technologies for the assessment of marine and coastal ecosystems
Abstract
This chapter reviews the Remote Sensing (RS) technologies that are particularly
appropriate for marine and coastal ecosystem research and management.
RS techniques are used to perform analysis of water quality in
coastal water bodies; to identify, characterize and analyze river plumes; to
extract estuarine/coastal sandy bodies; to identify beach features/patterns;
and to evaluate the changes and integrity (health) of the coastal lagoon
habitats. For effective management of these ecosystems, it is essential to
have satellite data available and complementary accurate information
about the current state of the coastal regions, in addition to well-informed
forecasts about its future state. In recent years, the use of space, air and
ground-based RS strategies has allowed for the rapid data collection,
Image processing (Pixel-Based and Object-Based Image Analysis (OBIA)
classification) and dissemination of such information to reduce
vulnerability
to natural hazards, anthropic pressures, and to monitoring
essential ecological processes, life support systems and biological

A Influência da Prática Regular de Desporto nas Habilidades Motoras e na Aptidão Física dos Alunos
Objetivo: O presente trabalho de investigação tem como principal objetivo aferir se a Prática Regular de Desporto influencia ou não as habilidades motoras, a aptidão física e a composição corporal dos alunos. Complementarmente pretendeu-se identificar a correlação existente entre o desempenho dos alunos nos testes de habilidades motoras específicas do futebol, a aptidão física e a composição corporal. Material e Métodos: para a realização do estudo, a amostra total foi constituída por 160 alunos, do género masculino, todos com 12 anos de idade, residentes na Ilha da Madeira e praticantes da modalidade de futebol. A amostra foi dividida em dois grupos com 80 alunos cada. Um grupo com os alunos que para além da AF letiva tinham também uma AF extracurricular, regular, supervisionada, periodizada (Desporto Federado). O outro grupo com os alunos em que a AF se resume à prática AF letiva (Desporto Escolar). Avaliaram-se também os valores da composição corporal (IMC e % MG) e aplicou-se a bateria de testes do Fitnessgram para avaliar a aptidão física dos alunos. Para aferir as habilidades motoras dos alunos, aplicou-se uma bateria de testes da Federação Portuguesa de Futebol (1986), adaptada pela Associação de Futebol da Madeira (2009). Para a análise e tratamento dos dados foi utilizado o programa informático Predivtive Analytics Software – PASW – versão 18.0 para Windows.
Resultados: Após a análise dos resultados verificou-se que os alunos com AF Extracurricular, obtêm em média melhores resultados nas habilidades motoras do que os alunos com AF letiva. Este resultado é talvez o menos surpreendente no conjunto de todas as avaliações devido ao maior tempo de empenhamento motor destes com a modalidade do que os alunos da AF letiva. Relativamente à aptidão física, os alunos com AF Extracurricular conseguem colocar mais alunos em ZSAF ou acima desta do que os alunos da AF letiva. Há também a registar no capítulo das aptidões que, no que se refere à extensão e flexão de braços, 26% dos alunos da AF letiva estão acima da ZSAF, conseguindo uma melhor performance do que os alunos da AF Extracurricular. No conjunto das aptidões aferidas os alunos da AF Extracurricular conseguem uma média superior relativamente aos alunos da AF letiva. No que se refere à composição corporal e depois de determinar o IMC e a %MG de cada grupo, verifica-se que os alunos da AF Extracurricular conseguem melhores resultados dos que os alcançados pelos alunos da AF letiva.
Conclusão: A prática regular de desporto com uma AF regular e extracurricular, parece contribuir para uma melhoria da aptidão física, das habilidades motoras e da composição corporal dos alunos, mantendo-os numa zona saudável de aptidão física, evitando desta forma, o aparecimento prematuro de doenças cardiovasculares, entre outras.Aim: This research work aims to assess if the regular practice of sports influences or not motor skills, physical fitness and body composition of students. Additionally it is sought to identify the correlation between the performance of students in specific motor skills tests of football, physical fitness and body composition.
Material and Methods: For the study, the total sample consisted of 160 12-year-old male students, living in Madeira and that practice football regularly. The sample was divided into two groups of 80 students each. One group of students had a regular, supervised, periodized (Federated Sports) extracurricular physical activity beyond curricular physical activity. The other group entails students who only practice physical activities as a curricular activity (School Sport). The values of body composition (BMI and% BF) were also evaluated and the Fitnessgram test battery was applied to assess the physical fitness of students. To check motor abilities of students, a battery of tests of the Portuguese Football Federation (1986), adapted by the Football Association of Madeira (2009) was applied. The software Predivtive Analytics Software – PASW - version 18.0 for Windows was used for analysing and processing data.
Results: After analysing the results we became aware that students with extracurricular physical activities get better results on average in motor skills than students with curricular physical activities. This result is perhaps the less surprising in the set of all assessments due to the longer physical commitment of these students in relation to the students that only exercise in the context of curricular activities. Regarding physical fitness, students with extracurricular physical activity can put more students at or above ZSAF than students with curricular physical activity. It is also mentioned in the chapter skills that, with regard to the extension and flexion of arms, 26% of the students with curricular physical activity are above ZSAF, achieving better performance than the students that have extracurricular physical activity. Within the set of the skills measured, the students with extracurricular physical activities achieve a relatively higher average than students with curricular physical activities. With regard to body composition and after determining the BMI and% the BF of each group, it appears that students with extracurricular physical activities achieve better results than those achieved by the students of curricular physical activities.
Conclusion: The regular practice of sports with curricular and extracurricular physical activities, seems to contribute to an improvement of physical fitness, motor skills and body composition of students, keeping them in a healthy fitness zone, thus preventing the premature onset of cardiovascular diseases, among others
