This manuscript continues the study of separability in the context of regular unit sphere packings, i.e., infinite sets of unit spheres P= ∞ [ xi + Sd−1 i=1 ∗ University of Calgary, Centre for Computational and Discrete Geometry (Department of Mathematics &
The phantom study was performed on a PET/CT system using the IEC Phantom with spheres filled with different sphere/background activity ratios (RS/B).
Solve real-world and mathematical problems involving volume of cylinders, cones and spheres Standard:
For tiny spherical bubbles, the drag coefficients coincide with those of corresponding rigid spheres.
