Isomerization and Redox Tuning: Reorganizing the Maya Blue Puzzle from Synthetic, Spectral, and Electrochemical Issues
A new approach to describe the composition of Maya blue (MB), an ancient organic-inorganic hybrid material, is presented. It is based on the analysis of attenuated total reflection-Fourier transform infrared (ATR-FTIR), ...
Design of experiments and focused grid search for neural network parameter optimization
(2016-04-19)
The present work offers some contributions to the area of surface roughness modeling by Artificial Neural Networks (ANNs) in machining processes. It proposes a method for an optimized project of a Multi-Layer Perceptron ...
Tuning: um estudo sobre a otimização de desempenho de sistemas gerenciadores de banco de dados relacionais sob carga de trabalho de suporte a decisão
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilTecnologia em Sistemas para InternetUTFPR, 2013-12-04)
The Relational Database Management Systems are more and more required for handling complex databases and with large data volumes. Consequently present the need more accurate performance. In this context, we stands out the ...
Statistical tuning of Adaptive-Weight Depth Map Algorithm
(Springer Berlin Heidelberg, 2011)
In depth map generation, the settings of the algorithm parameters to yield an accurate disparity estimation are usually chosen empirically or based on unplanned experiments -- A systematic statistical approach including ...
Estudo e aplicação de tuning em sistema gerenciador de banco de dados orientado a documentos
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de InformáticaTecnologia em Análise e Desenvolvimento de SistemasUTFPR, 2019-11-05)
The processing of large volumes of data in a timely manner revealed process limitations and storage of relational database management system. To get around these problems, appeared new systems that do not use the relational ...
Regression analysis of mean quality-adjusted survival time based on pseudo-observations
(JOHN WILEY & SONS LTD, 2009)
Regression models for the mean quality-adjusted survival time are specified from hazard functions of transitions between two states and the mean quality-adjusted survival time may be a complex function of covariates. We ...
Tuning of Adaptive Weight Depth Map Generation Algorithms Exploratory Data Analysis and Design of Computer Experiments (DOCE)
(Springer Verlag, 2013-09)
In depth map generation algorithms, parameters settings to yield an accurate disparity map estimation are usually chosen empirically or based on un planned experiments -- Algorithms' performance is measured based on the ...
A meta-methodology for improving land cover and land use classification with SAR imagery
(2020-03-01)
Per-point classification is a traditional method for remote sensing data classification, and for radar data in particular. Compared with optical data, the discriminative power of radar data is quite limited, for most ...
