This paper deals with some reflections on the use of educational games in the teaching and learning process, as well as describes the design of a contemporary game called Fractio, which aims to help students in the process of learning the theme 1374 Giancarlo de França Aguiar et al. Fractions, heavily worked content in Initial series of basic education. The use of games for learning is a fruitful space of meaning, and that enhances knowledge through virtual space. Such a space can enable children to reinvent and construct new knowledge, as well as giving new meanings to many concepts, which in general have an abstract character for children in the initial grades.
In this paper it is illustrated a scenario of power generation systems and their main concerns. It presents the regulation IEC 61850 and talks about the importance of management in managing assets by providing dealerships energy services. Introduces comments on power transformers and investigates the major dimensions that impact on the life of these power devices.
In this paper we propose a new algorithm for finding a feasible initial solution to transportation problems. The MOMC Method (Maximum Supply with Minimum Cost) as it was called, was compared with three classical methods: Corner Northwest, Minimum Cost and Vogel, obtaining significant results (better than the methods shown). A numerical example was presented to a rigorous understanding of the algorithm, and the results in a case study with a transportation problem with fuzzy parameters after the application of a classification technique showed great computational advantage (higher processing speed and less use of memory).
This paper explores a study of coalitions for decision making in division of joint costs. For this, it uses a methodology called Shapley Value (found in the literature as an application of game theory) to find a decision of cost sharing (either apportionment of profits). In this paper a numerical example is illustrated and its solution obtained from the modeling using the Microsoft Excel and solver optimization tool.
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.
