The Hidden Human Factors in Unmanned Aerial Vehicles [PDF]

, 2008
In April 2006, an Unmanned Aerial Vehicle crashed near Nogales, Arizona. This incident is of interest because it triggered one of the most sustained studies into the causes of failure involving such a vehicle.

Automated corrosion surface quantification in steel transmission towers using UAV photogrammetry and deep convolutional neural networks

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 14, Page 2050-2070, 3 June 2025.
Abstract Corrosion in steel transmission towers poses a challenge to structural integrity and safety, requiring efficient detection methods. Traditional visual inspections are unsustainable due to the complexity and volume of structures. Their manual, qualitative, and subjective nature often leads to inconsistencies in maintenance planning.

Unmanned Aircraft Systems (UAS) Traffic Management (UTM) National Campaign II [PDF]

2018 AIAA Information Systems-AIAA Infotech @ Aerospace, 2018
The Unmanned Aircraft System (UAS) Traffic Management (UTM) effort at NASA aims to enable access to low-altitude airspace for small UAS. This goal is being pursued partly through partnerships that NASA has developed with the UAS stakeholder community, the FAA, other government agencies, and the designated FAA UAS Test Sites.

On‐Land Pinniped Classification of Multiple Species and Demographic Classes on Multiple Substrates Using Deep Learning and Aerial Imagery

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT Pinniped abundance and demographic monitoring is the foundation of informed decisions about conservation, management and protection. However, current aerial and on the ground monitoring techniques are generally resource intensive, may suffer detection error and can present hazards to on‐site surveyors.

The silver king in the Magic City: Observation of Atlantic tarpon Megalops atlanticus aggregation off Miami, Florida

Journal of Fish Biology, Volume 106, Issue 4, Page 1202-1213, April 2025.
Abstract Due to the logistical and financial challenges in studying migratory marine species, there is relatively limited knowledge of the reproductive biology, behavior, and habitat use of many ecologically important marine megafauna species, including the Atlantic tarpon Megalops atlanticus.

Using accelerometry tags to quantify gray whale foraging behavior

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract High‐resolution tri‐axial accelerometry biologging tags have quantitatively described behaviors in baleen whale species that forage using lunges and continuous ram filtration. However, detailed quantitative descriptions of foraging behaviors do not exist for gray whales, a unique baleen whale species that primarily uses benthic suction feeding

Deep learning models for analysis of non‐destructive evaluation data to evaluate reinforced concrete bridge decks: A survey

Engineering Reports, Volume 7, Issue 1, January 2025.
Application of deep learning (DL) for automatic condition assessment of bridge infrastructure has been on the rise in the last few years. However, the task of defect detection in subsurface of bridge decks using deep learning has not received the proper attention. A brief overview of the working principle of non‐destructive evaluation techniques and DL
