Modal identification of concrete arch dam by fully automated operational modal identification

Structures, 2021
Abstract Modal identification is a type of system identification, which studies on the modal parameters of systems by using modal test. In the case of using operational or ambient modal analysis, there is no need to measure excitation, and the system output data are adequate for identification purposes.

Modal analysis identification techniques

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2001
Summary: The objective is to give a general panorama of modal analysis identification techniques, as a detailed explanation is not possible due to the vast amount of available information concerning the many existing methods. Beginning with an introduction, followed by the various types of classification and a short historical note, the reader is led ...

Modality identification for heterogeneous face recognition

Multimedia Tools and Applications, 2016
Identifying the type of modalities of the query image which can be of types visual, NIR, digital camera, web camera etc. have been assumed to be available before face matching. This leads to a major drawback in achieving fully automated heterogeneous face recognition as real world scenarios cannot be reflected.

The Effects of Modality and Elaboration on Perceptual Identification

The Quarterly Journal of Experimental Psychology Section A, 1994
This paper describes two experiments on the effects of spoken and written priming on perceptual identification (visual word identification in Experiment 1 and auditory word identification in Experiment 2). Much previous work that has based the priming phase on the processing of word lists suggests that cross-modal priming (auditory-visual and visual ...

Modal Parameter Identification of Controlled Structures

Journal of Guidance, Control, and Dynamics, 1997
A simple procedure to extract the modal parameters of the closed-loop structural system is proposed. It is formulated by using the extended Kalman filter (EKF) technique. The unknown parameters are eigenfrequencies, damping ratios, mode shapes, and modal masses.

Simulation of on-orbit modal identification

Acta Astronautica, 1991
Abstract Modularly designed large orbital systems cannot be tested as a total structure on earth. Size, zero-g design and the existing atmosphere conflict with traditional structural dynamic qualification. In order to avoid the associated problems with terrestrial testing some form of on-orbit testing is likely to be used.
