Robust variable selection for nonlinear models with diverging number of parameters [PDF]

, 2014
We focus on the problem of simultaneous variable selection and estimation for nonlinear models based on modal regression (MR), when the number of coefficients diverges with sample size.

Dynamic Strain Measurements on Automotive and Aeronautic Composite Components by Means of Embedded Fiber Bragg Grating Sensors

Sensors, 2015
The measurement of the internal deformations occurring in real-life composite components is a very challenging task, especially for those components that are rather difficult to access. Optical fiber sensors can overcome such a problem, since they can be

Bridge damage detection based on vibration data: past and new developments [PDF]

, 2017
Overtime, bridge condition declines due to a number of degradation processes such as creep, corrosion, and cyclic loading, among others. Traditionally, vibration-based damage detection techniques in bridges have focused on monitoring changes to modal ...

Parameter Study of Statistics of Modal Parameter Estimates Using Automated Operational Modal Analysis [PDF]

For any modal parameter estimation (MPE) method, there are a few control inputs that can have an impact on the modal parameter estimates. These control inputs are typically involving parameters like the maximum model order and how many time values or frequency lines that should be included in the MPE.

RESEARCH REGARDING THE MODAL PARAMETERS IDENTIFICATION FOR METALLIC STRUCTURES (I) [PDF]

Fiabilitate şi Durabilitate, 2012
In this paper, starting from previous methods written by other authors, we present the theoretical background of the modal identification for hyperstatic metallic structures (in an own way).

Operational modal analysis using symbolic regression for a nonlinear vibration system

Journal of Low Frequency Noise, Vibration and Active Control, 2021
The existence of nonlinearity is an inevitable frequent occurrence that should be considered to accurately identify the modal parameters of a vibration system using operational modal analysis.

Research on improved modal parameter identification method using Hilbert-Huang transform

Measurement + Control, 2023
In the wind tunnel test, the full-bridge aeroelastic model needs to simulate both the shape and dynamic characteristics of the real bridge, and modal parameters are key dynamic parameters.

Does Treewidth Help in Modal Satisfiability?

, 2010
Many tractable algorithms for solving the Constraint Satisfaction Problem (CSP) have been developed using the notion of the treewidth of some graph derived from the input CSP instance.
