Neural networks for feature-extraction in multi-target classification
(Universidade Federal de São Carlos, 2020-08-21)
Multi-target learning is a prediction task where each data example is associated with multiple target-variables (outputs) simultaneously. One of the challenges in this research field is related to the high dimensionality ...
Modelos dinâmicos aplicados a sistemas de manufatura utilizando grafos de ligação: proposta de modificações
(Universidade Federal de São Carlos, 2020-08-24)
Companies compete in a fierce market, where the main focus is consumer satisfaction, forcing
them to respond dynamically to market changes and instabilities. Due to these factors, more
accurate, adaptable, robust and ...
Weldability of AA5083-O/H111 and naval GL D36 steel lap joints by friction stir welding
(Universidade Federal de São Carlos, 2021-01-25)
Steel structures welded with aluminum alloys, which combine the low cost and high mechanical strength of steel with the weight reduction and the excellent specific properties of the aluminum alloys, are in great demand. ...
Metabolic discrimination of citrus species resistant and susceptible to black spot disease using multi-platform-based metabolomic approach
(Universidade Federal de São Carlos, 2020-08-31)
Citrus black spot (CBS) caused by the fungus Phyllosticta citricarpa. CBS causes several economic damages to commercial citrus orchards, such as fruit blemishes and premature fruit drop, leading to yield loss. There are ...
Identidades e polinômios centrais com involução para a álgebra de Grassmann e álgebra das matrizes triangulares de ordem 3
(Universidade Federal de São Carlos, 2020-11-30)
Let F be an infinite field of characteristic different from 2. In this thesis we will study the polynomial identities and central polynomials with involution for two important classes of algebras. More precisely, we describe ...
Evaluation of the composition of electronic waste hard disk using spectroanalytical techniques: proposition of fast and simple methods
(Universidade Federal de São Carlos, 2020-12-17)
The electronic waste is a worldwide problem of great magnitude with 53.6 Mt of waste generated in 2019. Unfortunately, the recycling rate is still very low. It is estimated that only 2% of the electronic waste is recycled ...
Práticas sustentáveis e o impacto no desempenho de pequenas propriedades cafeeiras
