Implementation issues of the nearfield equivalent source imaging microphone array

TL;DR: The NESI technique proved effective in identifying broadband and non-stationary sources produced by the sources and to enhance the processing efficiency of the time-domain NESI, an eigensystem realization algorithm (ERA) is developed.

A condition assessment method for time-variant structures with incomplete measurements

TL;DR: In this paper, a two-stage structural system identification method was proposed based on a two stage strategy and incomplete structural acceleration responses, where the unknown structural response could be re-constructed with the average acceleration discrete algorithm in this stage.

Reduced order models for boundary feedback flow control

TL;DR: The proposed empirical balanced truncation method uses the Galerkin model with a chirp signal as input to produce the output in the eigensystem realization algorithm (ERA) to show that model reduction is still effective on ERA produced approximated systems.

Wavelets as a tool for systems analysis and control

TL;DR: Though wavelets have been used with all types of systems, the major focus of this survey is mechanical and electromechanical systems in addition to their controls, but the techniques presented can be applied to any category of dynamic systems such as economic, biological, and social systems.

Improvement of evaluation method for existing highway bridges

T-L Wang, +1 more
TL;DR: In this article, the authors conducted the damage detection and diagnosis of highway bridges by using modal parameters, such as frequencies, damping ratios, and Energy Transfer Ratio (ETR) index, as well as static data such as deflections and strains.
