A Convolutional Neural Network for Atmospheric thermal detection in Unmanned Aerial Vehicles
No full textBirds utilize atmospheric thermals, which are vertical columns of warm air generated by the uneven heating of the Earth\u27s surface, to conserve significant energy during flight, particularly over long migratory routes. This natural energy-saving strategy presents a compelling model for enhancing the endurance of Unmanned Aerial Vehicles (UAVs). This study aims to apply this biomimetic concept to UAVs to conserve onboard energy and thereby extend the drone\u27s operational flight time. The primary objective of this research is to develop and validate a method for a UAV to autonomously detect and utilize atmospheric thermals using a machine learning model to predict the presence of these updrafts in real-time. A Convolutional Neural Network (CNN) model was developed to predict whether the UAV is in an atmospheric thermal based on vertical error derived from its XYZ coordinates. Furthermore, the model incorporates gyroscope data (roll, pitch, and yaw) to determine the UAV\u27s position and orientation within the thermal. The quantitative analysis revealed that the CNN model accurately predicted the presence of atmospheric thermals by correlating vertical error with the UAV\u27s spatial coordinates and gyroscope data. The successful implementation of the CNN demonstrates that it is feasible for a UAV to autonomously identify and orient itself within atmospheric thermals using standard onboard sensors. This step advances energy-efficient UAVs mimicking bird soaring, using natural updrafts to extend flight time, reducing battery dependence, and enabling long missions like monitoring, surveillance, and sensing.https://commons.stmarytx.edu/msrjs/1048/thumbnail.jp

Importance of intervention
Get PDFDomestic violence is a global issue, and research extensively highlights its impact on individuals, especially children. This poster examines the detrimental effects of exposure to intimate partner violence (IPV) on children, such as attachment problems, intellectual and developmental disabilities (IDD), resilience, cognitive abilities, and trust. Despite growing awareness, there is still a lack of information on effective community and school interventions to aid affected children. The intent of this poster is to promote discussion on strategies for communities and schools to better assist children impacted by IPV.https://commons.stmarytx.edu/rscpos25/1013/thumbnail.jp
