Item Loss of product (cryogenic liquid) for filling of cars - tanks: production of liquid(INSTITUTO DE TECNOLOGIA, 2015) TORRINHA, Andrea da Silva; OLIVEIRA, Maria Socorro Frutuoso de; GUEDES, Megue Pinheiro; LEITE, Jandecy Cabral; José Antônio da Silva SouzaThe paper analyzes the loss of cryogenic liquids (oxygen and nitrogen) during the filling of tank cars, a critical stage in the transportation of these gases. Losses occur due to heat exchanges causing vaporization, internal pressure increase in tanks, and inadequate pump handling. Using field questionnaires, operational data, and literature review, the study suggests improvements such as better thermal insulation and operator training, emphasizing the economic and environmental impacts of such waste.Item Motion for a product to collect a sample of human stool and/or urine – KITLAB(INSTITUTO DE TECNOLOGIA, 2015) MELO, Cláudio Márcio Bizantino de; LEITE, Jandecy Cabral; Prof. Dr. Carlos Tavares da Costa JúniorThis paper presents an innovative product proposal for collecting stool and/or urine samples using the KITLAB device. It is a detachable container that can be installed directly on toilet bowls, enabling hygienic, practical, and hands-free collection. The design addresses contamination and discomfort issues associated with traditional sample collection methods, improving health service practices. Market research results showed broad public acceptance and commercial viability of the product.Item Multicriteria design of passive harmonic filters for industrial installations using evolutionary computation techniques(INSTITUTO DE TECNOLOGIA, 2015) LEITE, Jandecy Cabral; ABRIL, Ignácio Perez; AZEVEDO, Manoel Socorro Santos; NASCIMENTO, Manoel Henrique Reis do; MORAES, Nadime Mustafa; REIS, Ana Maria; Profa. Dra. Maria Adrina Paixão de Souza da Silva.This article presents a mathematical method and a computational tool based on Evolutionary Computation (NSGA II) for the multicriteria design of passive harmonic filters in industrial electrical systems. Focused on the Industrial Pole of Manaus (PIM), the study frames the harmonic compensation design as a multi-objective optimization problem, balancing harmonic distortion reduction with economic viability under Brazilian energy tariff structures. The developed tool automatically selects filter configurations and parameters, incorporating standards such as PRODIST-Module 8 and IEEE 519-92. Results demonstrate the effectiveness of the approach.Item Photovoltaic Generation System Applied in Isolated Communities in the Amazon(INSTITUTO DE TECNOLOGIA, 2015) CABRAL, Rômulo Pereira; PINHEIRO, Marcos Cesar Alves; LEITE, Jandecy Cabral; Bruno Marques ViegasThe study examines the application of photovoltaic systems in isolated communities in the Amazon, emphasizing technical feasibility and socioeconomic and environmental benefits. Drawing on data from the "Light for All" project, it demonstrates that solar energy is a sustainable alternative for remote regions, lowering fossil fuel costs and fostering local development.Item Procedures for risk assessment of critical slant prevention ergonomic work stations: a case study(INSTITUTO DE TECNOLOGIA, 2015) LEITE, Jandecy Cabral; QUEIROZ, Getúlio Lima de; BRITO JUNIOR, Jorge de Almeida; NASCIMENTO, Enily Vieira do; PIRES, Marcello Fonseca; Eduardo de Magalhães BragaThe study identifies risk factors affecting the performance of employees at Annapoly Indústria e Comércio LTDA, analyzing the impact of predisposing aspects of work-related occupational diseases. Using a qualitative-quantitative approach, the research emphasizes the importance of ergonomics in preventing musculoskeletal disorders (MSDs), proposing measures to improve working conditions and reduce health risks.Item Study of Quality and Reliability of Welding Process Reflow Component Technology BGA(INSTITUTO DE TECNOLOGIA, 2015) COSTA, Robson Marques; LEITE, Jandecy Cabral; VIEIRA, Antonio da Silva; LOPES, Raimundo Valdan Pereira; FUJIYAMA, Roberto Tetsuo; Prof. Dr. Carlos Tavares da Costa JúniorThis study analyzed the quality and reliability of the BGA component Reflow soldering process in notebook motherboard manufacturing. Using a qualitative-quantitative approach via case study methodology, cross-section and X-ray analyses were conducted to evaluate alignment, cracks, and voids. The findings confirmed compliance with international standards IPC-A-610E and IPC-7095B, indicating the process is reliable and cost-effective for industrial application.Item Uso do Controle Estatístico de Processo (CEP) na Gestão de Operações Produtivas em uma Indústria no Polo Industrial de Manaus(INSTITUTO DE TECNOLOGIA, 2015) OLIVEIRA, Sidney dos Santos; LEITE, Jandecy Cabral; SOUZA, José Antonio da Silva; OLIVEIRA, Rosimeire Freires Pereira; MAGALHÃES, Edilson MarquesMonitoring, fault detection, and defect visualization are strategic issues for product quality. The article demonstrates the use of Statistical Process Control (SPC) in managing productive operations, employing a methodology based on control chart analysis for production monitoring. The approach combines defect location graphs and visualizations, applied in a case study at a company in the Manaus Industrial Hub (PIM). Results show variability through statistical graphs, enabling corrections and improvements in production processes, enhancing company quality.Item Comparação do Impacto Ambiental duma Usina Elétrica quando Utiliza Motores de Óleo Combustível Pesado e quando Utiliza Motores a Gás(INSTITUTO DE TECNOLOGIA, 2013) SILVA, Wagner Ferreira; CAMPOS, Lucila Maria de Souza; MIGUEL, Paulo Augusto Cauchick; RODRIGUEZ, Jorge Laureano Moya; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesThe study compares the environmental impact of a power plant in the Brazilian Amazon when using heavy fuel oil (HFO) engines and natural gas engines. It analyzes emissions of pollutants such as CO, CO₂, NOx, SOx, and particulate matter, noting that gas engines emit less NOx and SOx but more CO and CO₂ per unit of power supplied.Item Logística Reversa de Pós-Consumo de Bateria de Celular(INSTITUTO DE TECNOLOGIA, 2012) SILVA, Carlos Américo de Souza; LEITE, Jandecy Cabral; VIEIRA, Kellen Bicho; MAGALHÃES, Edilson MarquesThis study examines reverse logistics as a tool for sustainable development, focusing on the proper disposal of mobile phone batteries, which contain heavy metals harmful to the environment. The research analyzed manufacturers, mobile operators, and consumers in the Manaus Industrial Pole (PIM), identifying challenges such as low consumer participation in the return process, despite the availability of return channels. The results emphasize the need for awareness campaigns and better-structured reverse channels to reduce improper disposal and promote recycling.Item Materiais compósitos de matriz poliéster reforçados com resíduos de madeira de diferentes morfologias(INSTITUTO DE TECNOLOGIA, 2013) LOPES, Carlos Eduardo Pinto; PEREIRA, Léo César de Oliveira; COSTA, Deibson Silva da; LOPES, Raimundo Valdan Pereira; PINTO, Vagner Barroso; LEITE, Jandecy Cabral; FUJIYAMA, Roberto Tetsuo; MAGALHÃES, Edilson MarquesThis study presents the production and characterization of polyester matrix composites reinforced with residues from the Amazon timber industry. Using Angelim Pedra wood powder in different particle sizes and weight fractions (6.86% and 10.86%), the composites were evaluated for their mechanical properties through tensile tests. The results showed that smaller particles increase tensile strength, indicating that the reuse of these residues is viable and contributes to industrial sustainability.
