Consensus-Based Sequential Estimation of Process Parameters via Industrial Wireless Sensor Networks [PDF]

open access: yesSensors, 2018
Process parameter estimation, to a large extent, determines the industrial production quality. However, limited sensors can be deployed in a traditional wired manner, which results in poor process parameter estimation in hostile environments.

Design of a Sequential Filtering Method Fully Equivalent to the Centralized Filter with Cross-Correlated Noise [PDF]

open access: yesSensors
This paper investigates the optimal fusion estimation problem for a class of multi-sensor systems, in which the measurement noises of distinct sensors are mutually cross-correlated and each measurement noise is correlated with the system process noise at

Land Subsidence Monitoring and Dynamic Prediction of Reclaimed Islands with Multi-Temporal InSAR Techniques in Xiamen and Zhangzhou Cities, China

open access: yesRemote Sensing, 2022
Artificial islands and land reclamation are one of the most important ways to expand urban space in coastal cities. Long-term consolidation of reclaimed material and compaction of marine sediments can cause ground subsidence, which may threaten the ...

A Method for Improved Flight Testing of Remotely Piloted Aircraft Using Multisine Inputs

open access: yesAerospace, 2020
Unless a segregated airspace and the corresponding clearances can be afforded, flight testing of remotely piloted aircraft is often done near the ground and within visual line-of-sight. In addition to the increased exposure to turbulence, this setup also
