One of the most commented subjects currently in companies that are looking for excellence is certainly the Industry 4.0. A technological advance that if not implemented in a successful way can cause the loss of competitiveness and non-survival of the company, on the contrary can make it a reference in the current market. It is natural that with the advancement of any segment we have doubts regarding its approach. The purpose of this article is to describe the concepts, applications and maturity levels of Industry 4.0, as well as to clarify its degree of maturity in relation to industrial automation that is also part of this concept, but that did not emerge from it. It also presents the main enabling technologies that drive it, its relevance and interaction in the industry and examples of companies that in Brazil are already applying the concepts of the current revolution and the technologies that characterize it.

No curso desta trajetória investigativa, muitas foram as alianças estabelecidas que ofereceram suporte, amparo e sustentação a este corpo-pesquisadora, corpoprofessora. Aliadas/os na minha experiência de existência, esses corpos-sujeitos produziram memórias e presenciaram algumas das inúmeras cicatrizes que carrego marcadas, ou não, no corpo. Vão para além de meus pensamentos e, talvez, seja impossível materializar certa gratidão pelos atos, abraços, laços, traços, afeto, cheiros, lágrimas, desejos, anseios, dores, medos. Enfim… se minha memória não conseguir capturar todos os corpos-sujeitos para torná-los públicos nas linhas a seguir, é porque, certamente, as lembranças volta e meia se embaralham, como devem ser.Família. Registrar qualquer tipo de agradecimento para vocês embarga minha voz, estimula o deslizar das lágrimas em meu rosto, produz palpitações e a sensação incrível de desejar continuar brigando, sorrindo e lutando juntas/os. Tata, Dadinho,

With the advancement of technology and the growth of large companies, small and medium-sized companies are facing great competition in the business market. In order to survive in the competitive marketplace, there was a need for these companies to use their resources in the best way, investing their money in ways that could keep their products or services to the highest quality possible, and cloud computing came to assist in this. With the proposal to provide the same services of a physical computational infrastructure in your company, but without the expenses of energy, maintenance, update, and security, besides the mobility to use the service anywhere, simply having communication with the internet, and paying only for what you use. This article aims to show the characteristics of cloud computing, implementation models, their qualities and risks, and, through a case study, demonstrate the reduction of expenses when using cloud computing, proving that the characteristic pay reduces the without reducing the quality of the product or service.

Decision-making for operational optimization Economic Load Dispatch (ELD) is one of the most important tasks in thermal power plants, which provides an economic condition for power generation systems. The aim of this paper is to analyze the application of evolutionary computational methods to determine the best situation of generation of the different units in a plant so that the total cost of fuel to be minimal and at the same time, ensuring that demand and total losses any time be equal to the total power generated. Various traditional methods have been developed for solving the Economic Load Dispatch, among them: lambda iteration, the gradient method, the Newton's method, and so others. They allow determining the ideal combination of output power of all generating units in order to meet the required demand without violation of the generators restrictions. This article presents an analysis of different mathematical methods to solve the problem of optimization in ELD. The results show a case study applied in a thermal power plant with 10 generating units considering the loss of power and its restrictions, using MATLAB tools by developed techniques with particle swarm algorithm.

This article intends to treat the ComplianceProgram as a way to combat environmental problems. Thus, the central issue is the following question: is it possible to address environmental problems through the implementation of the Compliance program? To solve this issue, the main objective of the article is to analyze the role of Compliance in addressing environmental problems. And specific objectives are to study environmental law in globalization and the concept of compliance. Therefore, the article was divided into three topics, the first dealing with Environmental Law in the Globalization era, the second on Compliance and the third on Compliance as an instrument to prevent environmental problems, where Environmental Compliance was analyzed in more detail. which are used by companies and public bodies to comply with environmental standards. As for the Methodology, the report of the results will be composed on the Inductive Logical basis. In the various phases of the Research, the Referent Techniques, Category, Operational Concept and Bibliographic Research will be used.
