Optimal fusion‐based localization method for tracking of smartphone user in tall complex buildings
CAAI Transactions on Intelligence Technology, Volume 8, Issue 4, Page 1104-1123, December 2023., 2023 Abstract In the event of a fire breaking out or in other complicated situations, a mobile computing solution combining the Internet of Things and wearable devices can actually assist tracking solutions for rescuing and evacuating people in multistory structures. Thus, it is crucial to increase the positioning technology's accuracy. The sequential Monte

IET Communications, Volume 17, Issue 17, Page 1962-1973, October 2023., 2023 This paper proposes the adaptive weighted federated Kalman filtering based on Mahalanobis distance (MD‐AWFKF). Firstly, by calculating the Mahalanobis distance between the predicted value and the measured value of the system state, the random fluctuation of the measured value is detected.

Antarctic Sedimentary Basins and Their Influence on Ice‐Sheet Dynamics
Reviews of Geophysics, Volume 61, Issue 3, September 2023., 2023 Abstract Knowledge of Antarctica's sedimentary basins builds our understanding of the coupled evolution of tectonics, ice, ocean, and climate. Sedimentary basins have properties distinct from basement‐dominated regions that impact ice‐sheet dynamics, potentially influencing future ice‐sheet change.

Geophysical Research Letters, Volume 50, Issue 11, 16 June 2023., 2023 Abstract The seafloor depths under the Cook Ice Shelf and Ninnis Glacier Tongue have not been directly measured, despite their importance for understanding ocean circulation and ice shelf change. We model the bathymetry underneath the floating ice and surrounding ocean using airborne gravity data.
