Finite element modelling and experimental study of oblique soccer ball bounce [PDF]

open access: yes, 2011
In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us

The effects of lapping load in finishing advanced ceramic balls on a novel eccentric lapping machine [PDF]

open access: yes, 2005
HIPed (Hot Isostatically Pressed) silicon nitride ball blanks were lapped from diameter 13.255 mm to diameter 12.7 mm by a novel eccentric lapping machine. A maximum material removal rate of 68 μm/hour has been achieved under a nominal lapping load of 43

Noncommutative Q-balls [PDF]

open access: yes, 2001
We obtain Q-ball solutions in noncommutative scalar field theory with a global U(1) invariance. The Q-ball solutions are shown to be classically and quantum mechanically stable.
