Semantic Segmentation of Weeds and Crops in Multispectral Images by Using a Convolutional Neural Networks Based on U-Net
(Springer, 2020)
Acceso restringido
A first step in the process of automating weed removal in precision agriculture is the semantic segmentation of crops, weeds and soil. Deep learning techniques based on convolutional neural networks are successfully applied ...
Factorial design for preparing chitosan nanoparticles and its use for loading and controlled release of indole-3-acetic acid with effect on hydroponic lettuce crops
(International Society of Biocatalysis and Agricultural Biotechnology, 2020)
Acceso restringido
The excessive use of agrochemicals generates damage to the environment, so their controlled release from biodegradable nanoparticles represents a good solution. In this study, chitosan nanoparticles (CNPs) were prepared ...
Software Curriculum Transformation at the University Level
(IEEE, 2020)
Acceso restringido
Many software-related degrees exist, and a diversity of programs makes it difficult for candidates to choose where they wish to study. Selecting the wrong program costs students time, money, and considerable effort. Though ...
Confined benzene within InOF-1: Contrasting CO2 and SO2 capture behaviours
(Royal Society of Chemistry, 2020)
Acceso restringido
The confinement of small amounts of benzene in InOF-1 (Bz@InOF-1) shows a contradictory behavior in the capture of CO2 and SO2. While the capture of CO2 is increased 1.6 times, compared to the pristine material, the capture ...
Treatment of irrigation water infested with nematodes using a solar photoreactor
(Desalination Publications, 2020)
Acceso restringido
The objective of this study was to assess the efficacy of the disinfection of irrigation water loaded with the plant-parasitic nematode Meloidogyne incognita using a solar photoreactor. The photoreactor was comprised of a ...
Water treatment plant prototype with ph control modeled on fuzzy logic for removing arsenic using fe(VI) and fe(III)
(Multidisciplinary Digital Publishing Institute, 2020)
Acceso abierto
This study proposes a fuzzy control strategy embedded in a Siemens IoT2040 gateway developed for removing inorganic arsenic from synthetic underground water in a treatment plant prototype. The prototype is used to dose a ...
Role of empowerment and identification with work teams in innovation climate
(Fundacao Getulio Vargas, Escola de Administracao de Empresas de Sao Paulo, 2020)
Acceso abierto
Several studies argue that an organizational climate oriented to promote innovation generates greater competitiveness in companies. However, very few researchers have explored the factors that lead to the formation of ...
Cellulose Microfibres Obtained from Agro-Industrial Tara Waste for Dye Adsorption in Water
(Springer, 2020)
Acceso restringido
Microfibres of cellulose were extracted from tara residues (TR), obtained after the production process, and used to remove dyes in aqueous solution. Caesalpinia spinosa (Molina) Kuntze or Tara spinosa, commonly known as ...
Which complexity characteristics do economical industries present?
(WIT Press, 2020)
Acceso abierto
The past decade has seen a development of complex theories in different fields, raising the question: should managers use complex principles in their strategy? The answer implies to analyze companies and economical industries ...
Indole-3-carbaldehyde Semicarbazone Derivatives: Synthesis, Characterization, and Antibacterial Activities
(Hindawi Limited, 2020)
Acceso abierto
The two-dimensional NMR (in acetone-d6) spectral data revealed that the molecules 1 and 2 in solution are in the cisE isomeric form. This evidence is supported by DFT calculations at the B3LYP/6-311++G(d,p) level of theory ...
