Utilização de NBR modificada com grupos 2-oxazolina em misturas de NBR/EVA

Disseminacao de mensagens DTN com base em grupos de interesses

Recent works explore social characteristics of nodes to improve message delivery rate in Delay Tolerant Networks (DTN). This work uses machine learning techniques to create node groups organized by common interests. Messages are sent to target groups, and from there to the final destination. Simulation results using The ONE simulator show that the larger the group size the higher the message de...

ALS-INHIBITING HERBICIDES Controle de Gramíneas Anuais com Topramezone em Misturas com Herbicidas Inibidores da ALS

Panicoid grasses are major weeds of maize and sugarcane as well as of several other important grains, including sorghum, pearl millet, and foxtail millet. Pot trials were conducted to study the activity and potential interactions of topramezone in mixture with recommended rates of rimsulfuron or nicosulfuron on three annual panicoid grasses (i.e. Echinochloa oryzoides, E. phyllopogon, and Panic...

Projeto otimizado de redes neurais artificiais para predição da rugosidade em processos de usinagem com a utilização da metodologia de projeto de experimentos

The present work offers some contributions to the area of surface roughness modeling by Artificial Neural Networks in machining processes. It proposes a method for the project of networks of MLP (Multi-Layer Perceptron) and RBF (Radial Basis Function) architectures optimized for prediction of Average Surface Roughness (Ra). The method is expressed in the format of an algorithm employing two tec...

Detecção e classificação de distúrbios de tensão usando redes neurais ARTMAP Euclidiana modificada com treinamento continuado

This research presents a methodology to detect and classify voltage disturbances in electrical distribution systems using as tool, statistical and multilevel direct analysis of voltage signals in wavelet domain for the detection process and modified Euclidean ARTMAP neural network with continuous training for the classification (ARTMAPMECT). These two tools provide velocity, security and reliab...
