Digital preservation of scientific information in Brazil: an initial approach of existing models [poster]
(Universidade de Brasília, 2012)
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. ...
Generating VHDL-AMS models of digital-to-analogue converters from MATLAB®/SIMULINK®
(2007-11-27)
Today, the trend within the electronics industry is for the use of rapid and advanced simulation methodologies in association with synthesis toolsets. This paper presents an approach developed to support mixed-signal circuit ...
Precision of yule-walker methods for the arma spectral model
(2004-12-01)
In this work a new method is proposed of separated estimation for the ARMA spectral model based on the modified Yule-Walker equations and on the least squares method. The proposal of the new method consists of performing ...
STREET REGION DETECTION FROM NORMALIZED DIGITAL SURFACE MODEL AND LASER DATA INTENSITY IMAGE
(Copernicus Gesellschaft Mbh, 2011-01-01)
The urban road network extraction process can be simplified by firstly detecting regions corresponding to streets, allowing a substantial reduction of the search area. As a result, the extraction process is benefited in ...

Automatic code generation for microcontrollers from place-transition Petri net models
(2011-12-01)
This paper describes a program for the automatic generation of code for Intel's 8051 microcontroller. The code is generated from a place-transition Petri net specification. Our goal is to minimize programming time. The ...
The use of tuned filters as an attenuator device of harmonics generated by multipulse converters
(2011-05-31)
The purpose of this paper is to present a computer model that enables the operation analysis of a tuned filter as an attenuator device of harmonic generated 12 and 18-pulses converters with Y-generalized differential ...
