Abstract The identification of the modal parameters from frequency response functions is a subject that is not new. However, the starting point often comes from the equations that govern the dynamic motion. In this paper, a novel approach is shown, resulting from an analysis that starts on the dissipated energy per cycle of vibration. Numerical and experimental examples were used in order to as...
How extremely low frequency (ELF) electromagnetic fields (such as power line exposure) impacts brain activity is today an intense area of research. One challenge is to unveil transduction mechanisms allowing ELF to interact with brain tissue. Thus, we present a cortical network model receiving internal and external stimuli. Using frequency analysis, we study how these stimuli durably modulate n...
This paper deals with the evaluations of lower and upper bounds dynamic responses natural frequencies for structures uncertain interval parameters. The structural physical parameters, geometric dimensions initial conditions can be considered as modified Chebyshev method (MCIM) is presented to handle uncertainties. In comparison (CIM), MICM provides tighter time without a significant increase in...
Condition monitoring of large power transformers is paramount importance in systems. One the most common indicators transformer aging moisture content oil. In this article, a capacitive sensor able to online measuring presented. The output recorded using Frequency Response Analysis (FRA) device. Comparing FRA results degraded oil with reference test, can be determined. A prototype has been desi...
