Population growth at a global level implies an increase in energy consumption by the population. This increase is expected in urban agglomerations composed of residences. The production of energy in the residential area has been discussed when talking about selfsufficiency and clean and sustainable energy. An aggravating factor in the context of forms of energy generation is the great impact of burning fossil fuels that release polluting gases when producing electricity. The present study sought to discuss, based on the literature, the use of photovoltaic panels in the generation of clean energy in homes as an alternative to conventional means. Therefore, the methodology used was based on the search for scientific studies in databases about the proposed theme. A bibliographic survey was carried out in order to obtain studies that would support the research. Studies in the databases Periódicos CAPES, Scholar Google and Scopus were found and selected based on certain criteria. Therefore, it was found that the use of photovoltaic panels in the generation of energy for homes is promising in reducing other energy sources. Several studies show the viability of this type of energy in homes in Brazil, which has a large availability of daily sunlight for its operation. However, the technology in question still has a high implementation cost, which may decrease with government incentives and a decrease in the values of its components. In addition, the use of solar energy compared to conventional means of energy generation has a compensatory value with its long-term use.
Industrial automation brings a new generation to industry development 4.0. A fourth generation of industrial boosters, machines, processes, and people connect as a collaborative community. In Brazilian industries, there is a technology deployment process 4.0, but at what level of development? The purpose of this article is to promote a discussion among authors of various papers on the magnification of industry 4.0 nationally. How is the work methodology, adopting the development of a bibliographical revision, with the use of published, printed and printed books, in order to explore the context and work areas of the industry 4.0. As a result, one analyzes several concepts, exposes the challenges and discusses two industrial forms.
In view of the current scenario found in the factory as to the effective removal of the printed circuit board from the production conveyor and realizes the connection of the HDMI, RCA, power and USB connector cables manually to perform the receiver test, taking into account View the time required to make the cable connections considered high within the current context. Considering the time wasted on the connection of the cables to test the receiver, this case study seeks to implement a solution to make the connections more efficiently optimizing the test process. This research has as its aim to seek an improvement for the digital receiver manufacturing industry in the industrial center of Manaus due to the need to maximize productivity and especially the increase of cost benefit for the company in which the case study was carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
