An experimental investigation of quasireversible maximum (QRM) of azobenzene on mercury electrode by two methods, i.e., traditional square-wave voltammetry (SWV) and fast Fourier transformed square-wave voltammetry (FT-SWV), was presented, and the influence factors on QRM of FT-SWV were ...
We need to add an infinite number of sine waves, however, to retrieve the square wave exactly. The full sum is termed the Fourier Series of the square wave. Sign in to download full-size image FIGURE 6-15. Fourier analysis of a 1-D continuous square wave into its sine wave components...
By comparing the fractional Fourier series and the array factor, it is seen that the location of elements can be determined from the phase of eigenvalues. After specifying the location of elements, the least square method is used to determine the excitation currents. The differential spectrum ...
1). The external light is butt-coupled into and out of the chip using inverse tapers and adiabatically transitions to the highly confined quasi-TE mode of the access strip waveguide before splitting in the two arms of the interferometer and subsequently recombining into the output waveguide ...
of the inverse power series are zero and the problem becomes one of “beyond-all-orders” or “exponential” asymptotics. The method of steepest descent for integrals and other complex-path integration techniques can successfully connect the exponentially small behavior of the spectral coefficients to...
The transition regime gas flows, which are otherwise to be addressed through computationally intensive molecular simulations, become well tractable within the extended quasi-continuum framework without necessitating the use of any fitting parameters. Rigorous comparisons with direct simulation Monte Carlo (...
The standard Fourier pseudospectral (FPS) method is also implemented for a detailed comparison so that the performance of the DSC algorithm can be better evaluated. Three two-dimensional PDEs of different nature, the heat equation, the wave equation and the Navier–Stokes equation, are employed to...
Just wave excited phonons in quantum many body theory is called collective oscillation or quasi particle excitations. The chemical potential is zero phonon, bosons, obey the Bose Einstein statistics. Phonon itself does not have the momentum, but with quasi momentum, and with energy. 6 heat The ...

Fokker–Planck PDEs (including diffusions) for stable Lévy processes (including Wiener processes) on the joint space of positions and orientations play a major role in mechanics, robotics, image analysis, directional statistics and probability theory. E
