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.

The Amazon has the largest river basin in the world, with 20% of the planet's freshwater, made up of more than 20,000 km of navigable waterways and with 1/3 of the world's humid tropical forests. The Amazon represents almost 65% of the Brazilian territory. However, the Amazon suffers from serious data communication infrastructure problems, which undermines the level of socioeconomic development in the region. The geographical characteristics of the Amazon favor the means of river transport that serves the transport of cargo and passengers in the region. This work sought to present how the main IoT devices perform in a river environment, applied in the Catalão riverside community. The results showed that the devices have excellent wireless communication in this region of the Rio Negro, although the environment is not the most common application, the results serve as a basis for investment incentives.

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.

(2025-04-07) Silva, Rodrigo Pereira; Fialho, Edevaldo Albuquerque; http://lattes.cnpq.br/1681351413618686; Almeida, Fernando Rodrigues de; http://lattes.cnpq.br/5709421178806994; Santos, Renan Cavalcante; http://lattes.cnpq.br/6930748017205035; Oliveira, Ricardo Augusto Medeiros de; http://lattes.cnpq.br/3009905071972756
The advancement of Internet of Things (IoT) technologies enables new approaches to environmental monitoring, especially in remote and hard-to-reach areas such as the Amazon Rainforest. The need to track environmental changes, prevent deforestation and forest fires, and facilitate scientific research drives the development of autonomous technological solutions for data collection and transmission. In this context, this work proposes the development of an IoT-based telemetry system for remote forest monitoring, utilizing LoRa technology for communication within a mesh network. The system consists of two main devices: the Monitoring Node, responsible for measuring environmental parameters such as temperature, humidity, atmospheric pressure, and volatile organic compounds; and the Communication Bridge, which transmits the data to a monitoring center via the MQTT protocol. Laboratory and field tests demonstrated the system’s efficiency in data transmission. The results indicate that the proposed approach is viable for environmental monitoring applications and can be further improved with optimizations in energy consumption and the physical structure of the devices.

The main objective of this study was to design a Linear Quadratic Regulator (LQR) controller to stabilize an inverted pendulum in its vertical position, minimizing the position error and control energy consumption, while ensuring system stability. The specific objectives included defining the DC motor parameters, verifying the system stability, defining the optimal gain matrix K, determining the rank and controllability matrix, as well as simulations under different initial conditions. The methodology involved obtaining the parameters of a DC motor through experimental tests, such as measurements of armature resistance, current, angular velocity and moment of inertia. The system was modeled in state space based on the Euler-Lagrange equations, followed by linearization via Taylor series expansion and Jacobian matrix. The resulting linear model was implemented in the MATLAB/Simulink environment, where the LQR controller was developed and simulated. The results demonstrated that the originally unstable system presented full controllability (rank of the controllability matrix equal to 4) and was successfully stabilized. The cost function associated with the control was minimized using the Riccati equation, ensuring a balance between performance and control effort. The simulations proved the robustness of the controller against parametric variations and external disturbances, validating the effectiveness of the proposed approach.

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.
