Geomagnetic Field Based Indoor Landmark Classification Using Deep Learning
Published 2019-01-01“…In this paper, we introduce deep recurrent neural networks (DRNNs) to build a model that is capable of capturing long-range dependencies in variable-length input sequences. The use of DRNNs is brought from the idea that the spatial/temporal sequence of magnetic field values around a given area will create a unique pattern over time, despite multiple locations having the same magnetic field value. …”

Simulation study on the response characteristics of rock joints to cyclic shear load under constant normal stiffness boundary
Published 2025-04-01“…Loading frequency exhibited a linear proportionality to the number of cycles needed to reach the target shear displacement The fatigue damage degree of joints during cyclic shear could be represented by two indices: the Felicity ratio (FR) and the damage variable (D). Under different conditions, the critical D value ranged from 0.037 to 0.097, while the corresponding critical FR value varied between 0.700 and 0.822, reflecting the impact of normal stiffness, amplitude, and frequency on joint fatigue failure.…”
