Autor(es): Araujo, Kleibe Jacinto de Primeiro Orientador: Oliveira, Kelias de Abstract: The work presented here proposes to analyze the feasibility of implementing a low cost receiver based on Radio Defined by Software using a dongle RTL-SDR in the L1 band (1,57542 GHz) which is used by the GPS constellation. Using the Octave, it will be discussed how the GPS signal is captured, the output format of the sampled data and the presentation of the signal of interest. The work will analyze the feasibility of a receiver using the dongle RTL-SDR for real-time measurement of ionospheric scintillation.

It is common to find, in the most varied industrial segments, machines that perform tasks that were previously performed by a considerable group of people. This work will present the implementation of an automated picker using the Ethernet protocol inside a cold camera, whose objective will be to accelerate the activity of picking boxes and reduce the application of manual labor. Supported by several industrial automation studies, a prototype will be developed and implemented, consisting of a PLC (Programmable Logic Controller), inductive and capacitive sensors, actuators, pneumatic pistons, motors, etc. The separation of the boxes will be done according to the cycle time of each manufacturing equipment, and can be adjusted according to the needs of the production line. The detection and separation of the boxes will be developed so that there is a synchronism in the model recognition process, using the PLC's internal timed system together with the average speed of the conveyor and the Talkback of each sensor. In this way, it is expected that there will be no unnecessary stops in the industries. The automated separator will improve productivity and make it possible to reallocate 26 employees to other sectors of the company, thus saving on personnel.

Autor(es): Lopes, Sarah Heloísa de Souza Primeiro Orientador: Marques, Fábio da Silva Abstract: Building Information Modeling (BIM) is a transformative methodology that leverages intelligent 3D models enriched with multidisciplinary data (electrical, civil, and mechanical systems) to optimize decision-making across the lifecycle of infrastructure projects. This study investigates the implementation of BIM in electrical substations emphasizing its role in enhancing maintenance efficiency, operational safety, and sustainability within core power networks. Through a systematic literature review and analysis of case studies, this paper demonstrates how BIM-driven integration reduces design conflicts, streamlines asset management, and minimizes resource waste during substation construction and operation. Key findings reveal that BIM supports predictive maintenance strategies, enables real-time data sharing among stakeholders, and reduces lifecycle costs by up to 20% in analyzed scenarios. Furthermore, the adoption of BIM aligns with global sustainability goals by improving energy efficiency and reducing carbon footprints through optimized substation layouts and material usage. This research underscores BIM’s potential as a catalyst for modernizing power infrastructure, offering actionable insights for utilities and engineers seeking to balance technical precision with environmental responsibility.

In the state of Goiás, the high incidence of lightning directly impacts operational costs and maintenance planning of the utility. This study aimed to analyze the performance of transmission lines in Goiás under atmospheric surges, seeking to correlate outages with climatic variables and structural characteristics. The methodology involved the processing of data from the Environmental Climatic Monitoring System (SMAC), combined with outage records and structural data provided by Equatorial Energia Goiás. Python algorithms were applied to generate lightning density maps and to perform statistical analyses using Pearson correlation coefficients and the K-means clustering algorithm. The results indicated that the southern region of Goiás concentrates approximately 80% of the analyzed lightning events, with emphasis on the UTE Quirinópolis – Quirinópolis transmission line, which presented the highest susceptibility to lightning discharges, reaching 59 discharges per kilometer. Contrary to initial expectations, minimum humidity was identified as the climatic variable with the highest correlation to lightning occurrence. Regarding structural characteristics, the cluster-based analysis did not allow the establishment of a significant direct relationship between structural components and the number of outages. Thus, the use of lightning density maps is concluded to be an economically viable strategy for preventive maintenance of transmission lines, enabling optimized allocation of resources to critical sections and reinforcing the importance of integrating minimum humidity as a variable in maintenance alert systems.
