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
Prioridade Dinâmica de Mensagens Aplicada a Redes de Sensores Corporais Sem-Fio
TL;DR: QoSBody-AODV is proposed, a variation of the AODV routing protocol, which performs the dynamic adjustment of the message’s priority, turning the network functioning to be sensitive to the physical activities performed by the patient, as well as pathological information.
Proceedings ArticleDOI
Liquid Monitoring System in Industrial Tanks with Ultrasonic Sensor
TL;DR: A prototype of a monitoring system for liquids in industrial tanks with an ultrasonic sensor is developed and an open–source platform called Arduino is considered for the hardware in order to manage and interpret data from the sensor.
