Critical comments on EEG sensor space dynamical connectivity analysis

open access: yes, 2016
Many different analysis techniques have been developed and applied to EEG recordings that allow one to investigate how different brain areas interact. One particular class of methods, based on the linear parametric representation of multiple interacting ...

Time domain analysis of switching transient fields in high voltage substations [PDF]

open access: yes, 2009
Switching operations of circuit breakers and disconnect switches generate transient currents propagating along the substation busbars. At the moment of switching, the busbars temporarily acts as antennae radiating transient electromagnetic fields within ...

Time domain synchronisation estimation algorithm for FBMC vector signal analysis in 5G system

open access: yesThe Journal of Engineering, 2019
For the challenges of filter bank multi-carrier (FBMC) test applications in the fifth-generation mobile communication network (5G) system, presented is a time domain synchronisation estimation algorithm based on power synchronisation in frequency domain.

Acoustic Cavitation using Resonating MicroBubbles: Analysis in the Time-Domain

open access: yesSIAM Journal on Mathematical Analysis, 2023
We study the time-domain acoustic wave propagation in the presence of a micro-bubble. This micro-bubble is characterized by a mass density and bulk modulus which are both very small as compared to the ones of the background vacuum. The goal is to estimate the amount of pressure that is created very near (at a distance proportional to the radius of the ...

Analysis of blast load on a reinforced concrete column in the time domain

open access: yesMATEC Web of Conferences, 2017
This paper is concerned with simulation of the blast load on a reinforced concrete column for different design options with the use of the finite element technique in LS-DYNA. Calculations were made with regard to the gravity load.

Analysis of Transients in a Three-Level DC–DC Flying Capacitor Converter. Time Domain Approach

open access: yesPower Electronics and Drives, 2019
The paper considers a discrete state-space model for transients in a three-level flying capacitor DC–DC converter. A transition matrix is obtained for a pulse width modulation (PWM) period.

Reduced-order model for non-linear dynamic analysis of viscoelastic sandwich structures in time domain

open access: yesMATEC Web of Conferences, 2014
The present paper deals with the analysis of the dynamic behavior of viscoelastic sandwich structures with localized nonlinearities. The Golla-Hughes Mac Tavish (GHM) viscoelastic model is used and the finite elements procedure is established to derive ...

Gravitational Waveforms for Precessing, Quasi-circular Binaries via Multiple Scale Analysis and Uniform Asymptotics: The Near Spin Alignment Case

open access: yes, 2013
We calculate analytical gravitational waveforms in the time- and frequency-domain for precessing quasi-circular binaries with spins of arbitrary magnitude, but nearly aligned with the orbital angular momentum.
