Journal ArticleDOI
Efficient Volterra systems identification using hierarchical genetic algorithms
TL;DR: This work presents a robust hierarchical evolutionary technique which employs a heuristic initialization and provides robustness against noise in the Volterra series and improves on the computational complexity of existing methods without harming the identification accuracy.
Proceedings ArticleDOI
Análise Comparativa de Métodos para Esteganografia Digital em Imagens
TL;DR: A frequency-domain heuristic for reducing the visual impact of digital steganography in grayscale images is presented, and a Python language library was made available in the PyPI repository, allowing for both concealment and revelation of messages using the presented digital Steganography methods.
Proceedings ArticleDOI
Topology control optimization of wireless sensor networks for IoT applications
Jorge Augusto G. de Brito,Jurair R. de P. Junior,Felipe da Rocha Henriques,Laura Silva de Assis +3 more
TL;DR: An optimization methodology based on a Genetic Algorithm is proposed, in order to solve the Sensor Allocation Problem for a WSN, which defines the position of sensor nodes according to their different operation modes while pursuing the optimization of network efficiency with respect to performance parameters.
Proceedings ArticleDOI
Brazilian Soil Bulk Density Prediction Based on a Committee of Neural Regressors
Diego B. Haddad,Laura Silva de Assis,Luís Tarrataca,Andréa da Silva Gomes,Marcos Bacis Ceddia,Rosane Ferreira de Oliveira,Jurair R. de P. Junior,Diego N. Brandão +7 more
TL;DR: The proposed non-linear regressor presents higher precision when compared to the linear model, and requires less information to do so, and the developed solution brings to light the assumed relationship between soil bulk density and some soil chemical properties.
Proceedings ArticleDOI
Collaborative information system to find efficient routes using public transport
Diego H. B. Zanchett,Jurair R. de P. Junior,André Monteiro,Diego B. Haddad,Laura Silva de Assis +4 more
TL;DR: This paper addresses this lack of information on public bus services and presents ShareBus, an information system to improve urban mobility and uses the idea of collaboration to obtain and maintain data, either from users or companies, keeping it as much as possible updated.
