On the contact stiffness and nonlinear vibration of an elastic body with a rough surface in contact with a rigid flat surface
(Elsevier B.V., 2015-01-01)
The surface topography of engineering rough surfaces has an enormous influence on contact mechanics of the interface and further the dynamics of the contact system. In this paper, the force-deflection characteristic and ...
Analysis of the Frequency Dependent Lumped Parameter Transmission Line Model
(2020-11-12)
An accurate transmission line model must consider the frequency-dependence of the longitudinal parameters. In this context, the lumped parameter model (LPM), despite its well-known limitations, had been largely used to ...
Bayesian model identification of higher-order frequency response functions for structures assembled by bolted joints
(2021-04-01)
This paper proposes a procedure to identify a stochastic Bouc-Wen model for describing the dynamics of a structure assembled by bolted joints considering vibration data. The proposed identification approach is expressed ...
Technical condition assessment of masonry structural components using Frequency Response Function (FRF)
(International Masonry Society, 2016-01-01)
International standards indicate the need for adequate quality control in the production of masonry in the form of light bricks, double bricks, insulating bricks, breeze blocks, concrete blocks, etc. Quality control focuses ...
Analysis of control strategies based on virtual inertia for the improvement of frequency stability in an islanded grid with wind generators and battery energy storage systems
(2021)
Rising levels of non-synchronous generation in power systems are leading to increasing difficulties in primary frequency control. In response, there has been much research effort aimed at providing individual electronic ...
Analytical approach to understanding the effects of implementing fast-frequency response by wind turbines on the short-term operation of power systems
(2021)
The significant presence of variable-speed wind turbines in worldwide power systems has led to planners and grid operators requiring them to participate in frequency control tasks. To ad-dress this demand, a large number ...
Damage Detection Based on Electromechanical Impedance Principle and Principal Components
(2014-01-01)
This paper presents a novel time domain approach for Structural Health Monitoring (SHM) systems based on Electromechanical Impedance (EMI) principle and Principal Component Coefficients (PCC), also known as loadings. ...

Determining hydraulic connectivity of the coastal aquifer system of La Plata river estuary (Argentina) to the ocean by analysis of aquifer response to low-frequency tidal components
(Springer, 2021-04)
Seawater intrusion occurs in almost all coastal aquifers that are subject to human pressure. Its effects could be reduced by avoiding pumping in those wells better hydraulically connected to the sea. This paper presents a ...
