Can Recurrence Quantification Analysis Be Useful in the Interpretation of Airborne Turbulence Measurements?

Geophysical Research Letters
In airborne data or model outputs, clouds are often defined using information about Liquid Water Content (LWC). Unfortunately LWC is not enough to retrieve information about the dynamical boundary of the cloud, that is, volume of turbulent air around the

Analyzing the hydrological dynamics of a pristine and a regulated river in northern Europe’s sub-Arctic using recurrence theory

Hydrology Research
Examining hydrological variability is essential for understanding system dynamics and supporting effective water resource management. Recurrence analysis, a nonlinear time series technique, can uncover hidden patterns in hydrometeorological data through ...

Sliding Recurrence Analysis and its Application of Gear Vibration Signal

Jixie chuandong, 2015
According to the recurrence plot analysis to the gear vibration signal,it is found that there are obvious difference between the gear condition and the driver system characteristics represented by recurrence plots.If the recurrence plots are regarded as ...

A Comparative Study of RQA-Guided Attention Mechanisms with LSTM Autoencoder for Bearing Anomaly Detection

Sensors
Accurate anomaly detection in rotating machinery under noisy conditions remains challenging in Prognostics and Health Management (PHM). Existing deep learning autoencoders and attention mechanisms rely primarily on data-driven similarity measures and ...

Characterizing pelagic pair trawl partnerships using coordination metrics and behavior classification in the Black Sea

Ecological Informatics
Pelagic pair trawling involves two vessels towing a single midwater net in coordinated motion to target schooling pelagic species. Monitoring and distinguishing pair-trawl operations remain challenging for fisheries management, particularly when analyses

Laminar fMRI

Neuroimage, 2019
The cortex is a massively recurrent network, characterized by feedforward and feedback connections between brain areas as well as lateral connections within an area. Feedforward, horizontal and feedback responses largely activate separate layers of a cortical unit, meaning they can be dissociated by lamina-resolved neurophysiological techniques.
