GPS-Aided Gyroscope-Free Inertial Navigation Systems [PDF]

, 2002
A gyroscope-free inertial navigation system uses only accelerometers to compute navigation trajectories. It is a low-cost navigation system, but its output error diverges at a rate that is an order faster than that of a conventional gyroscope-based ...

Optimal deep learning activity recognition pipeline using animal bio‐logging data

Methods in Ecology and Evolution, EarlyView.
Abstract Animal activity recognition using supervised machine learning on bio‐logging data has revolutionized behavioural studies on wildlife and livestock over the past decade. These studies' analytic pipelines differ substantially though, being based on various sensors, features, algorithms and hyperparameter values, which has caused suboptimal or ...

Junctional sensitivity and atrophy progression rate of geographic atrophy secondary to age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the relationship between the baseline junctional retinal sensitivity measured with microperimetry and the atrophy progression rate in eyes with geographic atrophy (GA) secondary to age‐related macular degeneration. Methods In this prospective cohort study, patients with GA were examined with fundus autofluorescence (FAF ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Machine learning approaches in automated infant General Movements Assessment: A scoping review

Developmental Medicine &Child Neurology, EarlyView.
Automated infant General Movements Assessment increasingly uses machine‐ and deep‐learning approaches to classify movement patterns and estimate cerebral palsy risk from video or sensor data. This scoping review highlights how dataset characteristics, recording environment, pose‐estimation accuracy, feature extraction, and model design influence system
