In phase, waveforms are those where the phase difference between the two sinusoidal waves is zero. This happens only when the two waves have similar frequency and phase levels. For these in-phase waves, the retardation appears as an entire number of wavelengths such as 3, 4, 5…. The belo...
According to the wave optical description of holographic interferometry, the visibility and the phase of interference fringes are strongly influenced by the aperture of the observing optical instrument. An extra term appears in the phase difference formula compared to the usual one calculated by the ...
Phase difference formula resolver A phase difference type resolver is adapted such that a calculator calculates an angle from a phase difference at a detection-signal zero cross point, determines a velocity at the angle based on an angle calculated from a phase differenc... 神谷 巧,中村 健英,...
Among them are finite difference methods, finite element methods, spectral methods, discontinuous Galerkin methods and isogeometric methods. Section 5 focuses on two convergence theories of fully discrete numerical methods for phase field models. The first theory analyzes rates of convergence (or a ...
The accuracy of the simulation is 97.1% since there is a 2.9% difference between the diameter of the core/shell microdroplet derived from the simulation and the experimental results. Although axisymmetric models are uncommon, they can be a useful alternative to 3D modeling, which is a time-...
Harmonic signals are weighteed by the Black-man-Harris window, and analyzed by combining the principles of phase difference correction. Then the calculation formulae of fundamental and harmonics of the signal frequency, amplitude and initial phase are deduced. Moreover, the spectrum of the ...
is lower,the water cut is higher with the same s_w,especially, and the pressure gradient is bigger,which means the higher injection/production pressure difference.So, smaller well distance and higher injection/production pressure difference are needed for effectively developing low permeability ...
The colour of each separated region represents the difference in the nonlinear Chern number. c, Numerical demonstration of the absence of edge modes in the topologically trivial parameter region. We simulate the dynamics of the prototypical model of a nonlinear Chern insulator starting from an ...
This scheme evaluates the critical path for every ready task and computes the slack time, which is the time difference between the deadline and the critical path time. When the slack time reduces because of the failures or performance variations in the system, this algorithm switches to the on...
As the fluid solution in the PTFE U-tube is driven by the pressure difference in a tube, the triboelectric effect will cause the liquid solution to have a net positive charge, while the surface of the PTFE U-tube has an equal density of net negative charge. As the flow rate changes ...
