Cable Modal Parameter Identification. II: Modal Tests
Journal of Engineering Mechanics, 2009The cable dynamic stiffness describes the load – deformation behavior that reflects the cable intrinsic dynamic characteristics. It is defined as a ratio of response to excitation and represents a very similar frequency response property to the frequency response function (FRF). Therefore, by fitting both analytical cable dynamic stiffness and measured

Comparison of two dissimilar modal identification techniques
Journal of Guidance, Control, and Dynamics, 1992Recent laboratory results using a refined phase resonance method and the eigensystem realization algorithm on the same test structure are reported. These methods are dissimilar modal identification techniques suitable for future large spacecraft. The theory, application approach, and results obtained for each technique are summarized and compared ...

Multi-Modal Human Identification System
2005 Seventh IEEE Workshops on Applications of Computer Vision (WACV/MOTION'05) - Volume 1, 2005In this paper we describe our system for multi-source human identification. The system includes a collection of classifiers that classify feature streams derived from audio and video sources. We combine outputs of individual classifiers within our Approximate Bayesian combination framework.

Identification of Modal Parameters with Unknown Input
2003The techniques developed for structural identification are typically devoted to obtain a structural model on the base of information on the response and on the forcing action. In many situations, however, it can be necessary to refer only to the measured responses.

Identification of Modal Properties of Bridges
Journal of Structural Engineering, 1990Modal stiffness and damping are determined from experimental test data for a single‐span laboratory bridge model and a full‐scale three‐span highway bridge. Steady‐state vibration tests are conducted on both structures using an electro‐hydraulic actuator. Accelerations are recorded at selected locations on the structures.

Multi-Modal Aesthetic System for Person Identification
2021 International Conference on Cyberworlds (CW), 2021Aesthetic preference can be described as one's taste or fondness for a particular subject. This information has become ubiquitous as online communities and social media have grown increasingly integrated with daily life. The domain of social-behavioral biometrics analyzes the interactions, relations, and communications of individuals rather than ...

Modal Identification Using SMIT
2012The objective of this paper is to introduce a Structural Modal Identification Toolsuite (SMIT) for MATLAB that has been recently developed to facilitate system identification of structural systems. SMIT is an integrated toolbox, supporting a user-friendly Graphical User Interface (GUI) for modal identification.

Sensor placement for modal identification
Mechanical Systems and Signal Processing, 2012Abstract Planning of sensor placement can be done by using a finite element model before a modal test. In this paper, a method is proposed in order to select the most relevant degrees of freedom which should be monitored by sensors. It uses two criteria based on observability of mode shapes and on information shared by sensors.

Modal Identification of a Mechanical Structure
1999In this chapter a Scilab application concerning the identification of the modal characteristics of a mechanical structure under operating conditions is presented. The material covered in this chapter presupposes a knowledge of signal processing and the theory of vibration.

Identification of Blockage in a Pipe Using Modal Analysis
Volume 1: 23rd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2011The use of acoustic finite element modal analysis for simulating and identifying blockage in a pipe network is presented in this paper. The analysis commences with a straight fluid-filled pipe without any flaw. The natural frequencies of the acoustic modes of the fluid in the pipe are computed.
