Localization of a delamination and estimation of its length in a composite laminate beam by the VSHM and pattern recognition methods [PDF]
, 2010 The focus of this work is to investigate the delamination damage in laminate composite beams, to fix a Vibration-based Structural Health Monitoring (VSHM) method for the laminate structures.

Investigation of Resonance Avoidance Method for Vacuum Cleaner
IEEE Open Journal of Industry Applications, 2023 Electromagnetic resonance in electric motors arises when the electromagnetic force frequency coincides with any of the motor's natural frequencies, causing excessive vibration and noise.

Natural frequencies and the representation of risk [PDF]
International Journal for Quality in Health Care, 2002 To the Editor: The findings reported by Olsen and Gotzschel in a recent paper in The Lancet have re-sparked a heated controversy concerning the merits (or lack thereof) of mammography screening [1]. The dispute is not confined to the medical realm, but has political, economical, and ethical ramifications as well.

On a Fast Analytical Approximation of Natural Frequencies for Photovoltaic Modules
, 2020 In this paper, an eigenvalue problem is considered, i.e., the free vibration of photovoltaic (PV) modules. This structure was selected for its peculiar layer contrast, which forms an anti-sandwich.

Preferred Spatial Frequencies for Human Face Processing Are Associated with Optimal Class Discrimination in the Machine [PDF]
, 2008 Psychophysical studies suggest that humans preferentially use a narrow band of low spatial frequencies for face recognition. Here we asked whether artificial face recognition systems have an improved recognition performance at the same spatial ...

Natural vibration frequencies of delaminated composite beams
Computer Assisted Methods in Engineering and Science, 2023 In the presented work a model of a layered, delaminated composite beam based on the finite elements method was introduced. In this model the beam was divided into finite elements, while the delamination was modelled using additional boundary conditions.

International Journal of Naval Architecture and Ocean Engineering, 2014 : The main objective of this paper is to propose a new Finite Element (FE) model updating technique for damped beam structures. The present method consists of a FE model updating, a Degree of Freedom (DOF) reduction method and a damping matrix ...
