State of the art in electric batteries’ State-of-Health (SoH) estimation with m...
Sylvestrin, Giovane Ronei; Maciel, Joylan Nunes; Amorim, Marcio Luís Munhoz; Carmo, João Paulo; Afonso, José A.; Lopes, Sérgio F.The sustainable reuse of batteries after their first life in electric vehicles requires accurate state-of-health (SoH) estimation to ensure safe and efficient repurposing. This study applies the systematic ProKnow-C methodology to analyze the state of the art in SoH estimation using machine learning (ML). A bibliographic portfolio of 534 papers (from 2018 onward) was constructed, revealing key research trends. ...
Secret cryptographic key sharing through the integer partition function
Nobrega, Daniel Fernandes da; Amorim, Marcio Luís Munhoz; Lopes, Sérgio F.; Carmo, João Paulo Pereira; Afonso, José A.; Gazziro, MarioSecret key exchange is a necessary function for modern cryptography. The integer partition function is a mathematical function that arises from number theory. New methods for computing the integer partition function were developed and evaluated in the context of this paper, as well as new methods for using the integer partition function in a secret key exchange. The methods were categorized into single-variable...
Open-Source Data Logger System for Real-Time Monitoring and Fault Detection in ...
Amorim, Marcio Luís Munhoz; Lima, Jorge Gomes; Torres, Norah Nadia Sánchez; Afonso, José A.; Lopes, Sérgio F.; Carmo, João P. P. doThis paper presents the design and development of a proof-of-concept (PoC) open-source data logger system, designed for wireless data acquisition via Wi-Fi, aimed at bench testing and fault detection in combustion and electric engines. The system integrates several sensors, including accelerometers, microphones, thermocouples, and gas sensors, to monitor critical parameters such as vibration, sound, temperature...
