The aim is to reduce the workload of air traffic controllers, minimizing the possibility of human errors during critical moments of landing and takeoff. The proposed system uses runway visibility and cloud ceiling data, collected by equipment such as the Visibilometer and the Tetometer, to adjust the light intensity of the runway edge lighting. Simulations performed in MATLAB with real data demonstrated the feasibility of the proposal, with results comparable to decisions made by human operators.Item Otimização do Processo de Vendas com a Aplicação de uma RNA para Detecção de Oportunidades Abertas de Vendas para Empresa Soprojetos®(Instituto de Tecnologia, 2019) RABELO, Ary Ribeiro; BATISTA, Clauderino da SilvaWith the advent of Artificial Intelligence, computers can make appropriate decisions reliably using Machine Learning techniques, such as an Artificial Neural Network. This ability has a wide range of applications, including in the sales process, it is possible to optimize sales performance and make it easier for managers to decide the future directions of the organization. The present work aimed to apply an Artificial Neural Network (ANN) to detect open sales opportunities for Soprojetos® company, which, despite having a large amount of data recorded in the RDStation Marketing platform, still does not perform predictive analysis. With the support of Python Keras tools and the RDStation Marketing platform, it was possible to elaborate an algorithm to create an Artificial Neural Network capable of detecting sales opportunities for Soprojetos® company, using the data obtained on the RDStation platform, with the accuracy of 97.9% for the Validation Basis.Item Estudo para Reutilização de Resíduos Sólidos Secos Gerados em Escolas Públicas no Município de Santarém(Instituto de Tecnologia, 2019) NEVES, Daniela Cristina Pantoja; SOUZA, José Antônio da SilvaThe consumerist profile of the world population through industrialized products results in the growth of waste from its packaging. Therefore, environmental degradation becomes a fact that already suffers significant consequences in the global sphere, thus enhancing discussions with the aforementioned issue so that solutions to minimize the problem are idealized and effective. Thus, this study proposes the reuse of Dry Solid Residues (RSS) generated in state public schools of the municipality of Santarém (PA). The research was developed at the two largest public schools in the state of Pará, Brazil. The RSS was collected, related, quantified and weighed for one week, so that the annual estimate of unit, type, mass, gravimetric composition was to be used as a parameter for its reuse. As a result, it was verified the generation of 47 different items of RSS, with 79% packaging related to foodstuffs. The total mass was approximately half a ton with 498.167 kg / year. Regarding the type of RSS, aluminum is shown with 21.159 kg / year, plastic with 468.146 kg / year and glass with 8.862 kg / year. The gravimetric composition was around 4.25% aluminum, 93.97% plastic and 1.78% glass. The generated RSSs have potential for reuse in both teaching materials and utensils for use in school.Item Análise da Eficiência dos Protetores Auditivos Utilizados na Indústria da Construção Civil na Cidade de Manaus(Instituto de Tecnologia, 2019) AMORIM, Francisco Carlos Tavares; CUNHA, Edinaldo José de SousaThe construction industry provides occupational hazards to workers at construction sites. Despite the mandatory use of personal protective equipment (PPE), noise is one of the occupational hazards that persist as one of the most damaging to workers. This work aims to analyze the efficiency of hearing protectors, taking into account the octave band spectrum at the sound pressure levels of the main equipment used in the civil construction sector in the city of Manaus.Item Aplicação das Metodologias Lean no Processo da Gestão de Combustível na Estrada de Ferro Carajás(Instituto de Tecnologia, 2019) SILVA, Thiago Ferreira; MAGALHÃES, Edilson Marques; VIEGAS, Bruno MarquesThis dissertation takes place in the fuel management of Vale S/A railroad. As the work is developed, the project phases are guided according to diagnostics, applying a cyclical and continuous improvement along with the methodologies of study for the problems encountered. In view of this, we sought to implement a continuous process improvement project for critical fuel management activities through lean tools, in order to respect the principle of employing routines, easily communicable and understood by everyone in the organization. The main results are: team engagement from 32% to 64% (staff participation in the development of improvements), reflecting the increased problem resolution of the area (794 improvements) and reduction of supply time by 16%, increase productivity by 30% of the supply flow, and practice innovation in the method of training procedures, reducing operating costs and providing quality processes.Item Análise de Existência de Percolação em Barragem através da Integração de Métodos de Auscultação e Métodos Geofísicos(Instituto de Tecnologia, 2019) LOPES, Tiago Pantoja; SOUZA, José Antônio da SilvaClassical methods of dam auscultation, such as water level meters and piezometers, are widely used and provide satisfactory point responses for monitoring. However, these techniques need to be integrated with new methods for evaluating the stability and safety of earth dams. Geophysical methods, such as spontaneous potential and electrical resistivity, emerge as complementary tools to examine the internal and external structure of dams. This work demonstrates the application of these methods at the B6 dam, located in the Paragominas Mining, to identify signs of percolation and internal erosion, which are the main causes of dam failure. The results indicate the need for greater integration between auscultation and geophysical techniques for a more accurate and preventive assessment.Item Análise de Maturidade da Governança de TI e Capacidade de Implantação do Framework COBIT 5 em Operadoras de Saúde(Instituto de Tecnologia, 2019) SILVA, William Soares da; QUARESMA, João Nazareno NonatoThe corporate world daily seeks strategic and sustainable results, with Information Technology (IT) playing an increasingly crucial role. In the health operator sector, IT governance emerges as an ally to achieve a more controlled and sustainable environment. This study analyzes the maturity of IT governance and the capacity to implement the COBIT 5 framework in health operators of the Unimed system in the northern region of Brazil. Using a measurement framework based on the ISO/IEC 15504 standard, the capacity levels of COBIT 5 processes were evaluated. The results indicate that companies that adopt good process practices can improve their internal organization, facilitate administrative controls, and increase productivity and results.
