The effect of velocity on time dilation is orientation-independent but the Doppler effect depends on orientation, so when the vectors are not parallel, can the two inertial observers perceive a different Doppler effect? If we imagine that object B has coordinates (t,x0+vxt,y0+vyt...
r=a(9-sin \theta) and \frac{\mathrm{d} \theta}{\mathrm{d} t}=6, where a is a constant. Find the velocity and acceleration vectors in terms of u_r and u_{\theta} r = a \cos 2\theta and \frac{d \theta}{...

For this technical note, the influence of the main pipe flow velocity on the outflow and inflow through a crack on the pipe wall was studied in the laboratory. The experimental results show that the impact of the main pipe flow velocity can be significant. When the pressure difference across...
Accordingly, nonlinear effects on the time series as well as the maximum values of horizontal velocity, particle acceleration, and pressure gradient in the FSZs of solitary waves are presented. Before, at, and after the wave crest's intersection with a given measurement location, favorable, zero...

Meanwhile, the eigenvalues of type III PLL are placed to be the same position as those of a Chebyshev low-pass filter. In this way, demodulation parameters with stronger filter properties can be obtained to effectively suppress the high-frequency measurement noise in resolver signals. Thus, the ...
They conducted a finite element simulation to verify that during the impact process, the surface tensile force of the steel plate consumes part of the impact energy. The performance of the residual structure of CBSP panels mainly depends on the damage to the core concrete and the plastic ...
Sci. 2020, 10, 9095 2 of 22 small inertia, particles behave almost as tracers so that their relative velocity is given by the fluid velocity shear; therefore, the deviation of a uniform concentration distribution is responsible for an enhancement of collisions. In the other limit, of very ...
