Firstly, a three-dimensional model was developed to provide consistent predictions of 16 × 16-type spacer grids compression strength.
In this work, finite-element models were proposed to evaluate the spacer grids compression strength and structural behavior of fuel assemblies, mainly in terms of their natural frequencies.

The relatively lower MTF values corresponding to the raw image data could be attributed to the routine clinical practice conditions followed for this study, for example, grid, bucky, compression plate, and PMMA slabs in place.
In [10], the authors showed that if double compressed image is recompressed by aligning the DCT grid with the primary compression grid, histogram of the resultant DCT coefficients shows higher magnitude.
Usually, secondary compression grids do not overlap with the primary compression grids of the tampered region.
Due to the nonalignment of DCT compression grids, tampered region still follows this logarithmic distribution.
The buckling strengths and constraint factors of various grids under uniaxial compression and tension were achieved.
It is difficult to create a good tampering by aligning 8 × 8 DCT compression grids of the tampered region.
Both these approaches can cope with acceptable lossy attacks such cropping (by embedding a synchronization grid) and JPEG compression.
Thus, local compressive strain, ln(s/s o ), and tensile strain, ln (w/w o ), were determined by taking measurements of grid lines during compression.
In a typical application, the reference grid can be used to produce an exponential compression of the grid at a boundary, while the solution adaptive weights are used to make the grid spacing inversely proportional to the gradient (when the gradient is large) of some solution being computed on the grid.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
