An efficient codification to solve distribution network reconfiguration for loss reduction problem
(2009-12-17)
Evolutionary algorithms have been used to try to solve distribution network reconfiguration for loss reduction problem with a certain degree of success. But some problems, specially related to a codification that is able ...
Static converter: didactic support software
(1994-01-01)
Teaching a course of special electric loads in a continuing education program to power engineers is a difficult task because they are not familiarized with switching topology circuits. Normally, in a typical program, many ...
A petri net based timing model for hardware/software co-design of digital systems
(2004-12-01)
We have recently proposed an extension to Petri nets in order to be able to directly deal with all aspects of embedded digital systems. This extension is meant to be used as an internal model of our co-design environment. ...
Dynamics of a continuous flash fermentation for butanol production
(2010-12-27)
The ABE (acetone, butanol, ethanol) fermentation is characterized by its low productivity. In this paper, this issue is overcome with an innovative industrial process that employs the flash fermentation technology. The ...
A genetic algorithm for crop rotation
(2012-06-13)
In the last few years, crop rotation has gained attention due to its economic, environmental and social importance which explains why it can be highly beneficial for farmers. This paper presents a mathematical model for ...
Motivating Engineering Students to Math Classes: practical experience teaching Ordinary Differential Equations

Modelling of the influence of the layer pollution thickness in high voltage polluted insulators
(1995-12-01)
An experimental model and a mathematical model with the introduction of a ramp in the channel of Obenaus model are presented. The aim is to present a better reproduction of the real layer pollution deposited on the HV ...
Recognizing Possibilities of Computational Tinking When Teaching First-degree Equations
(Assoc Computing Machinery, 2019-01-01)
This work aims to present a hands-on activity for the first degree equations. The activity was applied to a reinforcement class of the K-8, in a public school in Birigui, Sao Paulo, Brazil. The activity used the Balance ...
A study on automatic methods based on mathematical morphology for Martian dust devil tracks detection
(2011-11-28)
This paper presents three methods for automatic detection of dust devils tracks in images of Mars. The methods are mainly based on Mathematical Morphology and results of their performance are analyzed and compared. A dataset ...
