Evolução de um sistema laguna-barreira da formação Rio Bonito, no sul da Bacia do Paraná
(Universidade do Vale do Rio dos Sinos, 2016-07-29)
This study aimed to construct and interpret a computational model for a particular lagoon-barrier system of the Rio Bonito Formation in Paraná Basin, located in the coalfield Iruí Central. This paper also presents a ...
Desenvolvimento de um sistema para dimensionamento, análise e otimização de circuitos de preparação de minérios
(Universidade Federal de Minas GeraisUFMG, 2013-02-28)
Before an execution of a mineral plant design, several simulations are realized to predict and minimize some errors. There are computational resources that help with these predictions, however these software are complex, ...
Operating room scheduling under waiting time constraints: the Chilean GES plan.
In 2000, Chile introduced profound health reforms to achieve a more equitable and fairer system (GES plan). The reforms established a maximum waiting time between diagnosis and treatment for a set of diseases, described ...
Case study: Discrete element modeling of wear in mining hoppers
(Elsevier Ltd, 2019)
A discrete element method is designed to evaluate the relative wear on hoppers caused by friction during operation in an open-pit mine. The results of the model show good agreement with measurements on real industrial ...
Critical adsorption of polyelectrolytes onto planar and convex highly charged surfaces: the nonlinear Poisson-Boltzmann approach
(Iop Publishing Ltd, 2016-08-18)
We study the adsorption-desorption transition of polyelectrolyte chains onto planar, cylindrical and spherical surfaces with arbitrarily high surface charge densities by massive Monte Carlo computer simulations. We examine ...
Optimal selection and location of fixed-step capacitor banks in distribution networks using a discrete version of the vortex search algorithm
(Cartagena de Indias, 2020-09-19)
This paper deals with the problem of the optimal selection of capacitor banks in electrical AC distribution systems for minimizing the costs of energy losses during a year of operation through a discrete version of the ...
Mapas cognitivos fuzzy dinâmicos aplicados na exploração de ambientes desconhecidos inspirados em robótica de enxame
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia de Controle e AutomaçãoUTFPR, 2019-04-22)
This work proposes the study of the use of Dynamic Fuzzy Cognitive Maps (DFCM) for the coordination of robots in a multi-agent system (SMA), inspired by swarm robotics and agent architecture, especially the subsumption ...
El aprendizaje del Puente de Wheatstone como medidor de resistencia en corriente continua.
(Escuela Superior Politécnica de Chimborazo, 2017-06-09)
The article describes the process of learning from the theoretical foundation and its
relation to practical application Wheatstone bridge as a resistance meter supplied
with direct current circuit during the semester ...
Sobretensões em redes de distribuição decorrentes da incidência de descargas atmosféricas em torres de telecomunicações
(Universidade Federal de Minas GeraisUFMG, 2007-12-14)
The number of radio-base telecommunication stations has been increasing significantly in urban areas. These stations are installed next to electric supplying distribution systems and always include elevated structures such ...
Photonics of fungal cell wall
(Cornell University, 2021-04-22)
The cell wall serves as a mechanical protection for the fungi and controls the traffic of molecules entering the cell. However, the optical role of the cell wall has not been fully investigated. In this work, we use a ...
