In science:

Processing delay: this includes pulse shaping, filtering, buffering delays 2.
On Superluminal Propagation and Information Velocity
The total processing delay Tp is the sum of pulse-shaping delay(Tps), receive filter delay(Tf) and miscellaneous delays such as buffering and other filters(Tmisc).
On Superluminal Propagation and Information Velocity
The correct density values from the top grid are placed in this buffer.
Multiscale Gaussian Random Fields for Cosmological Simulations
Because our subvolume is not centered but rather is placed in the corner of the cube of size 2rMs , we wrap half of the buffer to the other side of this cube.
Multiscale Gaussian Random Fields for Cosmological Simulations
Fig. 10.— Slices through the density (left) and velocity (x-component, right) fields on the coarse grid after a buffer region of width 16 Mpc has been placed around the 32 Mpc subvolume in the upper left.
Multiscale Gaussian Random Fields for Cosmological Simulations
The buffer regions and periodic boundary conditions are needed because of the FFT-based method for convolution with anti-aliasing filters.
Multiscale Gaussian Random Fields for Cosmological Simulations
Convolution across the discontinuity at the boundary of the buffer region causes some errors but these are small within the desired refinement region (the upper left quadrant in these images).
Multiscale Gaussian Random Fields for Cosmological Simulations
It is also much more localized than the exact filter, so that spurious effects from the buffer truncation in the left panel of Figure 15 are not convolved into the subvolume.
Multiscale Gaussian Random Fields for Cosmological Simulations
However, these errors are smaller than the error made with the exact filter due to the buffer truncation (top left panel).
Multiscale Gaussian Random Fields for Cosmological Simulations
They could be further reduced, at the expense of an increase in computer time and memory, by increasing the size of the buffer region for the top grid.
Multiscale Gaussian Random Fields for Cosmological Simulations
The top row is the same as Figure 15 except that the buffer has been unwrapped to surround the volume.
Multiscale Gaussian Random Fields for Cosmological Simulations
In other words, it is the discontinuities at the edge of the buffer region (shown in Figure 15) that cause problems.
Multiscale Gaussian Random Fields for Cosmological Simulations
However, when the top grid is refined by r = 2 in a subvolume of half its size, the doubling used for the convolution has a fortunate side effect: the buffer region fills out the volume so that the entire top grid is included.
