Title: Ferramenta mmbarcada para diagnóstico e simulação de comunicação Modbus Abstract: This work presents the development of a portable and multifunctional embedded tool for Modbus RTU communication analysis, logging, and simulation, aimed at the maintenance and diagnostics of industrial networks in the field. Based on an STM32F407 microcontroller with a touchscreen graphical interface, the device operates in three modes selectable at runtime: master, slave, and sniffer/datalogger, with support for RS-232 and RS-485 interfaces. The firmware was structured around a custom Hardware Abstraction Layer (HAL) based on opaque pointers and dependency injection, easing maintenance and code portability. The results confirmed correct operation in all three modes, with reliable traffic capture and continuous frame logging to an SD card with timestamps. As a contribution, this work delivers a compact tool to support maintenance, diagnostics, testing, and educational activities related to Modbus RTU networks.

Title: Análise da eficiência logística no transporte de madeira com pentatrens em uma fábrica de celulose com Simulação de Eventos Discretos Abstract: This course conclusion work aims to study, analyze, and implement improvements in the logistics process of a dry wood pulp factory, using the concepts of Discrete Event Simulation. The purpose of this study is to understand each stage of the process and analyze it both individually and as a whole, in order to identify possible bottlenecks and optimization points that may be preventing the process from reaching its full performance capacity. To ensure better understanding, some logistics concepts, Discrete Event Modeling, and the tools that can be used to simulate systems will be explained. In order to measure essential parameters for the analysis, factors such as travel time, cargo capacity, average distance traveled, number of daily trips, and others will be monitored and measured. In this context, the study aims to demonstrate the applicability of Discrete Event Simulation in everyday scenarios, through the resolution of a real case from the job market, highlighting the importance of this field of study and its correlation with Engineering.

Title: Análise de desempenho de controladores em uma unidade experimental de tanques em série Abstract: The appropriate selection of control strategies is essential to ensure the stability, performance, and efficiency of industrial processes. Tank systems configured in series are widely used in sectors such as chemical, petrochemical, and water treatment, and require precise control techniques due to their dynamic characteristics and inter-stage coupling. In this context, this project proposes a performance analysis of conventional Proportional-Integral-Derivative Control and Model Predictive Control applied to the level control of the second tank in an experimental two-tank-in-series setup. The entire system was developed from scratch, including the physical structure, electronic design with printed circuit board, and a graphical interface for real-time monitoring. Additionally, the embedded implementations and all analyses were conducted on open-source platforms, with a particular focus on the programming languages Python and C++. The study aims to understand the advantages, limitations, and practical applications of each control method, exploring open-source tools to support decision-making in real-world industrial automation projects.

Title: Kit didático para a disciplina de Eletrônica Industrial e Acionamentos Abstract: This project aims to address the lack of control devices for switching power transistors, such as MOSFETs and IGBTs, in the Industrial Electronics and Drives laboratories, used in DC-DC and DC-AC converters. Many configurations of these converters require isolated control circuits. The development of the educational kit will focus on meeting the specific applications of these converters, providing students with a comprehensive practical experience and improving the quality of practical learning in the discipline. This ensures that students gain a deep and applied understanding of switching and control techniques in electronic converters.
