Autonomous UAV Exploration and Mapping in Uncharted Terrain Through Boundary-Driven Strategy
Coelho, Fabricio O.; Pinto, Milena Faria; Biundini, Iago Z.; Castro, Gabriel G. R.; Andrade, Fabio Augusto de Alcantara; Marcato, Andre L. M. (Journal article; Peer reviewed, 2024)Unmanned Aerial Vehicles (UAVs) play a crucial role in exploring unpredictable terrains, such as accident sites and search zones. These robots require autonomous navigation and precise path planning to operate safely and ... -
Comprehensive Direct Georeferencing of Aerial Images for Unmanned Aerial Systems Applications
Correia, Carlos A. M.; Andrade, Fabio Augusto de Alcantara; Sivertsen, Agnar Holten; Guedes, Ihannah Pinto; Pinto, Milena Faria; Manhães, Aline Gesualdi; Haddad, Diego Barreto (Peer reviewed; Journal article, 2022)Optical image sensors are the most common remote sensing data acquisition devices present in Unmanned Aerial Systems (UAS). In this context, assigning a location in a geographic frame of reference to the acquired image is ... -
Computer Vision Based Path Following for Autonomous Unammed Aerial Systems in Unburied Pipeline Onshore Inspection
da Silva, Yago M. R.; Andrade, Fabio Augusto de Alcantara; Sousa, Lucas; de Castro, Gabriel G. R.; Dias, João T.; Berger, Guido; Lima, José; Pinto, Milena F. (Peer reviewed; Journal article, 2022)Unmanned Aerial Systems (UAS) are becoming more attractive in diverse applications due to their efficiency in performing tasks with a reduced time execution, covering a larger area, and lowering human risks at harmful ... -
Fuzzy Gain-Scheduling PID for UAV Position and Altitude Controllers
Melo, Aurelio G.; Andrade, Fabio Augusto de Alcantara; Guedes, Ihannah P.; Carvalho, Guilherme F.; Zachi, Alessandro R. L.; Pinto, Milena F. (Peer reviewed; Journal article, 2022)Unmanned aerial vehicle (UAV) applications have evolved to a wide range of fields in the last decade. One of the main challenges in autonomous tasks is the UAV stability during maneuvers. Thus, attitude and position control ... -

(Peer reviewed; Journal article, 2024)This research presents a cooperation strategy for a heterogeneous group of robots that comprises two Unmanned Aerial Vehicles (UAVs) and one Unmanned Ground Vehicles (UGVs) to perform tasks in dynamic scenarios. This paper ... -
Post-Processing Air Temperature Weather Forecast Using Artificial Neural Networks with Measurements from Meteorological Stations
Araujo, Gustavo; Andrade, Fabio Augusto de Alcantara (Peer reviewed; Journal article, 2022)Human beings attempt to accurately predict the weather based on their knowledge of climate. The Norwegian Meteorological Institute is responsible for climate-related matters in Norway, and among its contributions is the ... -
Transient Analysis of a Selective Partial-Update LMS Algorithm
Siqueira, Newton N.; Resende, Leonardo C.; Andrade, Fabio Augusto de Alcantara; Pimenta, Rodrigo M. S.; Haddad, Diego B.; Petraglia, Mariane R. (Journal article; Peer reviewed, 2024)In applications where large-order filters are needed, the computational load of adaptive filtering algorithms can become prohibitively expensive. In this paper, a comprehensive analysis of a selective partial-update least ...
