Automation of Tambaqui Fish Pond Aeration for Energy Efficiency in the Brazilian Amazon
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022) BINATTI, Fabio Cavalcante; OLIVEIRA, Edson Farias de
The increase in the demand for fish highlights the aquaculture potential of the Brazilian Amazon. The high cost of electric energy, lack of technical staff, and the absence of continuous control of water quality parameters are some of the factors that hinder the growth of this activity. This study evaluated two opportunities for automation and optimization in commercial tambaqui farms in ponds in Amazonas, Brazil. The first is the manual control and recording of physical-chemical properties of the water, and the second is the high consumption of electricity by the aerators. Thus, we developed continuous monitoring of water quality parameters through automatic gauging, using a floating platform with onboard sensors, called the Autonomous Experimental Station (AES), which controls the startup and shutdown of the aerators according to established parameters, providing the oxygen necessary for maintaining fish life, eliminating electricity waste, and recording the evaluated parameters. As a result, after integrating the AES in excavated tanks, it was possible to reduce 26% in electric energy consumption for adult fish and 52% for juvenile fish, besides registering the values of DO, pH, and temperature, generating savings for the producer and contributing to the sustainability of the activity in the Amazon.
Avaliação da Distorção Harmônica Total de Tensão no Ponto de Acoplamento Comum Industrial Usando o Processo KDD Baseado em Medição
(Universidade Federal do Pará, 2018) OLIVEIRA, Edson Farias de; TOSTES, Maria Emília de Lima
In recent decades, the transformation industry has introduced increasingly faster and more energy-efficient products for residential, commercial, and industrial use. However, these loads, due to their non-linearity, have significantly contributed to increased voltage harmonic distortion levels, according to Power Quality indicators. This thesis proposes a procedure based on the Knowledge Discovery in Databases (KDD) process to identify impactful loads on voltage harmonic distortions at the Point of Common Coupling (PCC). The methodology involves data collection and analysis with data mining techniques such as Decision Tree and Naïve Bayes applied to data collected by quality meters installed at the main loads and the PCC of an industrial consumer. The process includes data collection, cleaning, transformation, and evaluation steps. The results showed that the KDD process is applicable in analyzing Total Harmonic Distortion of Voltage, allowing the identification of the most impactful loads, with the most significant being the seventh current harmonic of the air conditioning units.
Estratégias para logística de suprimento de KITs de produtos de informática em uma empresa do Pólo Industrial de Manaus - PIM
(INSTITUTO DE TECNOLOGIA, 2010) FREITAS, Carlos Alberto Oliveira de; OLIVEIRA, Edson Farias de; OLIVEIRA, Haroldo Melo de; SOUZA, João Carlos Rodrigues de; MAGALHÃES, Edilson Marques
The article examines logistics strategies for supplying IT product kits in the Manaus Industrial Hub (PIM), focusing on transport modal choices (maritime, multimodal, and air) amid regional challenges and the 2008 financial crisis. The studied company initially adopted multimodal transport (Sea/Air) but switched to air freight due to customs delays and material shortages, ensuring speed despite higher costs. The study evaluates service dimensions (speed, consistency, capability, availability, and frequency) and underscores the role of logistics planning in maintaining PIM’s competitiveness.
Harmonic Impact analysis coming from the manufacturing processes of a Eletroeletrônica Industry Using KDD and Decision Trees
(INSTITUTO DE TECNOLOGIA, 2015) NOGUEIRA, Rildo de Mendonça; OLIVEIRA, Edson Farias de; SILVA, Waterloo Ferreira da; SANTANA, Ádamo L.; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota; Profa. Dra. Maria Adrina Paixão de Souza da Silva.
The study analyzes the impact of harmonic distortions generated by non-linear loads (computers, notebooks, and tablets) on the electrical grid of an electronics industry in Manaus. Using the KDD (Knowledge Discovery in Databases) methodology and decision trees, data were collected over a week at different points in the production process. The results identified that the 5th and 7th order harmonics, originating from the tablet production line, contributed the most to the total harmonic distortion of voltage (THDv) at the common coupling point (PCC). The decision tree technique proved effective in classifying and prioritizing distortion sources, aiding in decision-making for impact mitigation.
Naive Bayes aplicados en el análisis de impactos armónicos en los sistemas eléctricos industriales
(INSTITUTO DE TECNOLOGIA, 2015) SILVA, Waterloo Ferreira da; NOGUEIRA, Rildo de Mendonça; OLIVEIRA, Edson Farias de; SANTANA, Ádamo L.; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota; Prof Dr. Walter Barra Junior
This paper presents an analysis of harmonic current impacts in an industrial facility in the Manaus Industrial Zone using Naive Bayes classification, a data mining technique. The study measures total harmonic distortion (THDv) and identifies which production processes contribute most to power quality issues, particularly due to non-linear loads like switch-mode power supplies. The methodology includes power quality measurements and statistical analysis with dedicated software.
OTIMIZAÇÃO DO TEMPO DE TESTE FUNCIONAL DE PLACA DE CIRCUITO IMPRESSO MONTADA PARA COMPUTADOR PESSOAL
(Universidade Federal do Pará, 2012) OLIVEIRA, Edson Farias de; BLANCO, Cláudio José Cavalcante
The increasing competitiveness among companies in the same sector has made continuous process optimization essential to reduce costs. This study evaluates the time involved in the functional testing phase of motherboards produced in the Industrial Pole of Manaus and proposes improvements for optimization. A system for image capture was developed to analyze idle times, along with test devices and a proprietary Linux-based test system, replacing the previous system that depended on foreign suppliers. Percentage gains were demonstrated through four optimization proposals: unifying tests, performing simultaneous tests on two boards, replacing the test system, and automating the test device. The results obtained after implementing these improvements were positive, reinforcing the importance of applying scientific methodologies combined with innovation to optimize production processes.
Otimização do Tempo de Teste Funcional de Placa de Circuito Impresso Montada para Computador Pessoal
(Universidade Federal do Pará, 2012) OLIVEIRA, Edson Farias de; BLANCO, Claudio José Cavalcante
Increased competitiveness among the peer group has become increasingly important to the constant optimization of processes to consequently reduce manufacturing costs. The objective of this study is to assess the time involved in the functional testing phase of MBs produced in a company of the Industrial Pole of Manaus and propose improvements that lead to optimization of this phase. The actions taken with respect to optimizations led to the development system for capturing images to improve the analysis of downtimes and development of devices for testing, as well as the proprietary test system based on Linux to replace the previous system which relied of foreign partners. The percentage gains in the project was presented in four optimization proposals, the first being with the unification of the tests, the second with the test being performed on two board, the third with the replacement of the previous test by the system owner and end automation of the test device, which was demonstrated gains in each of the proposals. The results obtained after implementation of each proposal were positive and reinforce the need to apply scientific methods combined with creativity to achieve the optimization at any stage of the production process.
