We study the classical and quantal ionization dynamics of a one-dimensional system by strong, low-frequency electric fields with slowly varying envelopes. We show that classical ionization can be described using the principle of adiabatic invariance, if the driving frequency is sufficiently small, and that after ionization the atomic potential does not significantly alter the motion. This dynam...

In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, current harmonics compensation scenario is selected in order to avoid excessive injection of...

This paper proposes and compares two sound synthesis techniques to render a moving source for fixed receiver position based on indoor pass-by noise measurements. The approaches are the time-varying infinite impulse response (IIR) filtering spherical harmonics (SH) representation. central contribution of work is framework realistic transfer functions measured using static far-field microphone ar...

Accurate modelling of the Electric arc furnace (EAF) is necessary to study its impact on power systems. Here, a new model for EAF presented in which both non-linearity and time-varying characteristics are taken into account. The consists seven parallel current sources represent fundamental harmonic currents. Magnitude phase magnitude second seventh harmonics considered as updated every 0.01 s. ...

The Gaussian arbitrarily varying channel with input constraint r and state constraint 2 admits input sequences x = ( x l , , x , ~ ) of real numbers with Cxf 5 nT and state sequences s = ( 5 ,. , T , ~ ) of real numbers with L Y ~ 5 H A ; the output sequence x + s + V , where V = ( VI, , y , ) is a sequence of independent and identically distributed Gaussian random variables with mean 0 and var...

Aeronautical structures are commonly assembled with bolted joints in which friction phenomena, in combination with slapping in the joint, provide damping on the dynamic behaviour. Some models, mostly non linear, have consequently been developed and the harmonic balance method (HBM) is adapted to compute non linear response functions in the frequency domain. The basic idea is to develop the resp...

It is shown that a complex tone can be •nalyzed into its harmonics by adding to it a series of N -1 similar complex tones with uniformly spaced fundamental frequencies. The harmonics appear in a time-ordered sequence, and this is the basis of a computer music effect employed by composer Jean-Claude Risset. The mathematical derivation involves the summing of a geometric progression to form a slo...

This paper investigates the role of Static Var Compensator (SVC) on stability of voltage in grid system due to the presence of harmonics.. Here the design of SVC is based on the combination of Thyristor switched capacitors (TSC’s) and Thyristor controlled reactor (TCR) . TSC’s are used for switching the capacitor banks on and off while the TCR continuously controls the reactive power by varying...
