Experimental studies on multi‐scale data‐driven methods within the framework of structural health monitoring

Civil Engineering Design, Volume 7, Issue 4, Page 147-168, December 2025.
Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Automatic Analysis of Hydroacoustic Signals Related to the Activity of the Fani Maoré Submarine Volcano

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Due to the properties of sound propagation underwater, including the existence of the SOFAR channel, sounds in the ocean can propagate over large distances with little attenuation. This makes passive acoustics a relevant method for monitoring natural events such as ice calving, earthquakes, and underwater volcanic eruptions.

A Closed-Form Localization Algorithm and GDOP Analysis for Multiple TDOAs and Single TOA Based Hybrid Positioning

Applied Sciences, 2019
Cellular communication systems support mobile phones positioning function for Enhanced-911 (E-911) location requirements, but the positioning accuracy is poor. The fifth-generation (5G) cellular communication system can use indoor distribution systems to

Emitter Location Using Frequency Difference of Arrival Measurements Only

, 2022
It is desirable to enable emitter location using frequency difference of arrival (FDoA) measurements only, since many signals are characterized by coarse range resolution and fine Doppler resolution. For instance, while using the cross-ambiguity function

Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization

IEEE Open Journal of Signal Processing
Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.

PARTICLE SWARM OPTIMIZATION FOR TIME-DIFFERENCE-OF-ARRIVAL BASED LOCALIZATION

, 2008
Time-difference-of-arrival (TDOA) based source localization has been intensively studied and broadly applied in many fields. In this paper, particle swarm optimization (PSO) is employed for positioning with TDOA measurements in the circumstances of known

High-Precision Time Difference of Arrival Estimation Method Based on Phase Measurement

Remote Sensing
In unmanned aerial vehicle (UAV)-based time difference of arrival (TDOA) positioning technique, baselines are limited due to communication constraints. In this case, the accuracy is highly sensitive to the TDOA measurements’ error. This article primarily
