(2020-10-15) Silveira, Leone Raulino; Nascimento, José Fábio de Lima; Nascimento, José Fábio de Lima; Abreu, Luiz Henrique Portela de; Sampaio, Ricardo Brandão
This article presents the development of a low-cost 3D printer through fusion and deposition modeling, using the rapid prototyping method useful for making parts in a simple, inexpensive and personalized way. The vast majority of the project's components were printed on the 3D Creality printer, others purchased at the lowest price available on the market and the rest through the used retailer. The technologies used to build the machine were due to the interdisciplinary nature of the electrical, electronic, mechanical and programming areas so that they work in a systemic way. In order to avoid overheating due to the high current demand of the system, a thermal relay was used to protect the developed project. After assembling and calibrating the 3L Printer, quality and precision comparable to commercial printers was achieved. In addition, the overall cost of the project is below the average price of printers in the current market.

This undergraduate thesis details the development of a prototype for temperature control in a closed environment using PID control techniques. The prototype, housed in an MDF box, regulates a 100-watt lamp via a dimmer to maintain the voltage at 33 Vac. DHT11 and DS18B20 sensors are employed to monitor internal and external temperatures. Real-time sensor data is collected and analyzed through MATLAB-generated graphs. Cooling is facilitated by a 12Vdc fan controlled through PWM signals from the ESP8266 and a BC458 transistor. The PID control implementation, using the Arduino's PID_v1 library, is fine-tuned based on open loop responses and COHEN & COON relationships. Results highlight the energy consumption for cooling concerning the external temperature, establishing an effective temperature control solution for controlled environments.

Artificial Intelligence (AI) is not a contemporary concept, and its presence is not alien to society; currently, numerous applications employ this knowledge. However, despite the growing incorporation of technology in various contexts and increasingly in everyday life, a significant portion of the population still views technological intervention with reservations. In the medical field, it is no different; there is concern about the replacement of healthcare professionals by intelligent machines. Those who think so are mistaken; currently, AI is already involved in various aspects, such as disease prognosis, image understanding, interconnection of prescription databases, among others, and yet there is still a need for human presence. However, such advances do not spread uniformly; there will still be many gaps in the democratization of the application of this resource, whether due to a lack of technology, training, or even distances. In the latter case, it is more common in Brazil, which has continental extensions. According to the World Health Organization (WHO), in the last decade, two of the four leading causes of death in the world are related to respiratory diseases. In Brazil, according to the Ministry of Health, in the first nine months of 2022, there were more than 40,000 deaths from pneumonia alone. This work aims to compare machine learning algorithm models to present the pros and cons of each. Neural networks were used to check a dataset of images for training, validation, and testing of models with the purpose of recognizing and diagnosing cases of pneumonia through only X-ray examinations.

Estação meteorológica portátil com cultura maker interdisciplinar para ensino de física e programação de computadores
(2021-03-02) Melo, Larissa Alencar de; Frota, Vitor Bremgartner da; Frota, Vitor Bremgartner da; Souza, Daniel F. de; Fernandes, Priscila Silva
It is known that teaching physics can be considered difficult due to so many calculations, graphs and numbers. Often, the ability to associate formulas and theoretical content with everyday life does not happen clearly for students. In addition, teaching Computer Programming is also difficult for students, as they often lack the skills to understand the logical steps for solving problems using a computer. Therefore, the objective of the project presented in this article is to facilitate the teaching of Physics through the maker culture, in the do-it-yourself (DIY) process. As a case study to apply the maker culture to the teaching of Physics and Computer Programming, we created a portable meteorological station with Arduino, a low cost free hardware, so that students could relate Thermodynamics to Computer Programming, in this way seeking to improve the way of reasoning and visibility with the help of theoretical Physics, maker culture and everyday life. In the construction of this meteorological station, it was possible to study and visualize the state variables of Thermodynamics using Arduino as a monitoring platform. In our work, we were initially going to perform experiments in person, but we had to apply remote experiments due to the covid-19 pandemic. In this experiment, 20 second-year High School students of a technical course in Electronics participated from a science and technology institution in Brazil. All students were subjected to an initial test regarding concepts of Thermodynamics and Computer Programming, in order to obtain the initial diagnosis of these students. Then, all the students attended an online lesson from the Physics teacher and finally, the students were divided, through a draw, into 2 groups: the group that participated in the remote maker experiments (10 students) and the group that did not participate (10 students). We applied a final test to the whole class, in order to obtain the levels of expertise of the class regarding the concepts of Thermodynamics and Computer Programming. The results obtained, the comparison between the groups that participated and did not participate in the remote maker activities, the report of these remote experiences and the adjustments made to reach the largest possible number of students show the feasibility of the proposal, in addition to reported challenges and future directions.
