(Centro Universitário do Estado do Pará, 2021) Brito, Matheus Moraes de; Costa, Stefany Cristina Pinheiro; Santos, Michelle Bitar Lelis dos; http://lattes.cnpq.br/1208797288539861; Ribeiro, Moshe Dayan Sousa; http://lattes.cnpq.br/5200296393526606; Dias, Suzane Alfaia; http://lattes.cnpq.br/9675395702501834
The urbanization growth and world capitals industrialization were expressive in the last decades, although pollution problems, fuel and constant congestions threaten the efficiency of urban development. Electric vehicles are a promising option to contribute in the energy diversification and an alternative to polluting forms commonly used in urban and rural road infrastructure, despite the differences between the duration recharging and refueling times between the types of vehicles. The inteligente transportation systems represent the implementation of transport advanced technologies to sense and process road conditions to improve traffic fluidity and avoid accidents. In order to improve the efficiency of electric vehicle charging, the research proposes the integration of recharge infrastructure with intelligenttransportation systems as a way of assisting drivers and companies seeking to join the new ecological trend.

Genetic algorithms are used in a wide range of optimization problems, especially in combinatorial problems, where the search space is, in many occasions, too large for exact methods to achieve optimal solutions. This class of problems bear great importance for mathematical models that reflect real world situations, such as vehicle routing. The goal of this work is to utilize a genetic algorithm to optimize networked linked capacitated vehicles, in this configuration, all passengers and drivers positions are known in every moment. To make this optimization possible, the problem was mathematically modeled using the Capacitated Vehicle Routing Problem (CVRP) as inspiration with alterations reflecting the nature of the network linked capacitated vehicles. After that, this work also compares the obtained performance to a non-optimized route, so that the gain from using this method can be observed.
Cidades inteligentes com infraestrutura de comunicação 5G
(Centro Universitário do Estado do Pará, 2018-05-07) Teixeira, Cindy Emanueli da Silva; Silva, Luã Barros da; Cypriano, Tiago Morales; Santos, Michelle Bitar Lelis dos; http://lattes.cnpq.br/1208797288539861; Brito, Itamar Jorge Vilhena de; http://lattes.cnpq.br/5143837732124006; Sousa, Marcos Paulo Alves de; http://lattes.cnpq.br/6713232502495902
In a smart city, intelligent cars could communicate to smartphones, as well as traffic lights and other cars to anticipate traffic conditions and even to avoid collisions, it means that a large proportion of communication will take place between machines, not humans. In addition, with global mobile data traffic expected to grow eight times until the end of 2023, there is a need for more efficient technology, higher data rates and better spectrum utilization. New applications such as 4K / 8K video streaming, virtual reality and emerging industrial use cases will require greater bandwidth, increased capacity, security and lower latency, and this will only be possible with the use of 5G networks. There are already several initiatives of isolated intelligent cities in operation that offer a clue about what is to come with 5G technology and this work aims to demonstrate the operation of these intelligent cities using 5G resources and the requirements for its operation, as well as a theoretical proposal for the implementation of intelligent traffic lights in the city of Belém, which will bring a better operation of the city traffic and a new design in the city performance, bringing new opportunities for people, businesses, health and transportation.
Hórus: aplicação web para a localização de vagas em estacionamentos particulares em tempo real
(Centro Universitário do Estado do Pará, 2022-06-07) Santos, Franco de Assis Pinto dos; Silva, José Antônio de Carvalho; Carmo, Ricardo Melo Casseb do; http://lattes.cnpq.br/4933624262290855; Girotto, Pedro Henrique Sales; http://lattes.cnpq.br/0421749067951878; Cereja, Fabiola Alves; http://lattes.cnpq.br/4434149523451690
Increasingly, efforts are being made to optimize the time that each person spends during their day to day in order to focus on essential activities and this applies to the time spent commuting to activities that need to be carried out. The city of Belém notoriously has several problems in terms of urban mobility, which generates waste of this precious time and among these problems is the loss of time by drivers in finding parking spaces in the vicinity of their destination. This work seeks to solve this problem through an intelligent solution that allows, in real time, city drivers to locate parking spaces in the city close to their destination, through a web/mobile application built from the React and Expo libraries of Javascript, with integration with a Realtime Firebase database powered in real time by ultrasonic sensors connected to an ESP32. Surveys were carried out through Google Forms both on the interest with the application and for feedback on its final form, validating the product as viable.
Otimização dos tempos de um semáforo por processamento de imagem e controladores
(Centro Universitário do Estado do Pará, 2019) Silva, Raul Vitor Mesquita da; Corrêa Filho, Sérgio Teixeira; Brasil, Vitor Henrique Morais; Nascimento, Polyana Santos Fonseca; http://lattes.cnpq.br/6889523334917369; Brito, Itamar Jorge Vilhena de; http://lattes.cnpq.br/5143837732124006; Mendes, Marcelo Pinto da Costa; http://lattes.cnpq.br/3099832904134964
This course completion work has as main objective to provide an improvement to the flow of traffic with the optimization of traffic light times, through a digital image processing application and controllers. So that it is possible to create intelligent traffic lights that can contribute to a better traffic in big cities. The whole system has a set of scripts that use the Python language and its specific modules to perform different functions, such as digitally processing an urban traffic video, analyzing the state of the road and determining its state as light, moderate, intense flow and finally, to perform the optimization of the green signal time of a certain semaphore.
