Desenvolvimento de dashboard em power BI para gestão de indicadores de manutenção industrial This study presents the development of a dashboard for monitoring industrial maintenance indicators using the Power BI tool integrated with data from the SAP PM ERP system. The proposed model was developed to centralize previously decentralized information, standardize indicators, and improve the traceability of operational maintenance data. Data processing included standardization, data typing, inconsistency removal, and table merging using common keys to ensure consistency and reliability of the analyses. Indicators related to reliability, maintainability, and maintenance performance were structured to enable integrated monitoring of operational information. The results demonstrated greater agility in the development and monitoring of indicators, reduced dependence on manual controls, improved information organization, and enhanced support for analysis and decision-making. In addition, the model showed potential for replication in different industrial operations with standardized maintenance management structures.

Otimização de um simulador didático de sistema supervisório (SCADA) para disjuntores de alta tensão This work addresses the optimization of an educational Supervisory Control and Data Acquisition (SCADA) system simulator aimed at the control and monitoring of bistable circuit breakers in electrical power systems. The research is based on the Chronos prototype, previously developed to perform supervision, control, and data acquisition, as well as the analysis of overcurrent relay operating curves. The proposed optimization covered three main aspects: the development of a printed circuit board (PCB), replacing the breadboard assembly; the redesign of the Human-Machine Interface (HMI), prioritizing usability and clarity of information; and the implementation of an operational logic based on automatic circuit breaker state detection and continuous data transmission through bluetooth communication. The obtained results demonstrated significant improvements in operational stability, measurement reliability, and user experience. The implementation of the PCB contributed to noise reduction and increased system robustness, while the redesigned interface provided more intuitive interaction. Continuous communication enabled more efficient real-time supervision, eliminating the need for manual requests. Thus, the optimized system preserves the low-cost and flexible characteristics of the original prototype, consolidating itself as an effective educational tool for teaching automation, control, and protection of electrical power systems.

Metodologia para construção de uma bancada de ensaios para coletores solares Solar collectors are devices designed to capture solar radiation and convert it into thermal energy. To ensure the efficiency and reliability of these systems, it is essential to perform experimental tests during the development and validation stages. Thus, the objective is to develop the design and construction of a thermal solar collector test bench to evaluate the efficiency of solar collectors. The methodology adopted was experimental research, applied to the design, construction, and performance evaluation of the thermal solar collector test bench. During the development of the test bench, the initial system configuration made it possible to identify technical aspects that could be improved to better meet the requirements of the experimental tests. Based on this stage, adjustments were made to the hydraulic configuration and to the direction of the thermal fluid circulation, taking into account the principles of natural convection and the operating conditions required to obtain reliable measurements. These improvements contributed to the optimization of the experimental test bench, providing greater operational stability and more representative experimental results. At the end of the development process, the test bench demonstrated satisfactory performance in monitoring the main variables involved in the evaluation of thermal solar collectors, such as temperature, solar irradiance, and fluid flow rate. Therefore, the developed system proved to be a suitable tool for conducting experimental tests, enabling the analysis of the thermal behavior of solar collectors under different operating conditions and serving as a basis for future research and technological improvements.

Aplicação de redes neurais convolucionais na identificação de pontos quentes em redes de distribuição This work proposes the application of Convolutional Neural Networks for the automated detection of hotspots in electrical power distribution networks using thermographic images. The methodology adopts a two-stage processing architecture (Two-Stage Framework): in the first stage, the YOLOv8 algorithm performs the detection and spatial location of electrical assets—poles, switches, and cable terminations—; in the second stage, the U-Net network performs pixel-by-pixel semantic segmentation of the thermal anomalies identified in the segmented components. The dataset consisted of 500 thermographic images, obtained by a FLIR camera in a distribution network in the municipality of Belo Jardim (PE), with the application of data augmentation techniques to increase the sample variability.
