Industrie 4.0 Framework, Challenges and Perspectives

The world is increasingly in a global community. The rapid technological development of communication and information technologies allows the transmission of knowledge in real-time. In this context, it is imperative that the most developed countries are able to develop their own strategies to stimulate the industrial sector to keep up-to-date and being competitive in a dynamic and volatile global market so as to maintain its competitive capacities and by consequence, permits the maintenance of a pacific social state to meet the human and social needs of the nation. The path traced of competitiveness through technological differentiation in industrialization allows a wider and innovative field of research. Already we are facing a new phase of organization and industrial technology that begins to change the way we relate with the industry, society and the human interaction in the world of work in current standards. This Thesis, develop an analysis of Industrie 4.0 Framework, Challenges and Perspectives. Also, an analysis of German reality in facing to approach the future challenge in this theme, the competition expected to win in future global markets, points of domestic concerns felt in its industrial fabric household face this challenge and proposes recommendations for a more effective implementation of its own strategy. The methods of research consisted of a comprehensive review and strategically analysis of existing global literature on the topic, either directly or indirectly, in parallel with the analysis of questionnaires and data analysis performed by entities representing the industry at national and world global placement. The results found by this multilevel analysis, allowed concluding that this is a theme that is only in the beginning for construction the platform to engage the future Internet of Things in the industrial environment Industrie 4.0. This dissertation allows stimulate the need of achievements of more strategically and operational approach within the society itself as a whole to clarify the existing weaknesses in this area, so that the National Strategy can be implemented with effective approaches and planned actions for a direct training plan in a more efficiently path in education for the theme.

Estado atual da determinação do carbono no solo I: em solos contendo de 0,2 a 4,0% de carbono

O presente trabalho relata os dados obtidos na determinação do carbono por dois métodos diferentes em dez amostras de solo, cujo teor em C variava de 0,2-0,3% a 3,4-4,2%. Um dos métodos foi o baseado na combustão por via seca, a 550-600°C, associado à volumetria de gases. O outro método fundamentou-se na oxidação do carbono, com solução de dicromato a quente (banho-maria), titulando-se o excesso de oxidante por iodometria. Foram executadas cinco determinações em cada amostra de terra, pelos dois métodos estudados. Os dados obtidos evidenciaram que a precisão dos dois métodos foi similar. Entretanto, o método por via úmida forneceu sempre uma porcentagem de carbono inferior à obtida pelo método baseado na combustão por via seca. Assim, nas dez amostras estudadas, o método por via úmida forneceu de 68,8 a 93,4% do carbono determinado por combustão, por via seca. Finalmente, deve ser salientado que o método de combustão por via seca, associado com volumetria de gases, é muito mais rápido do que o por via úmida e determina todas as formas de carbono orgânico do solo.
