Calculating the correct IOL power for a patient who has undergone previous corneal refractive surgery is a challenge. Miscalculations in these patients have led in some cases to large “refractive ...

All electrical systems are susceptible to short circuits and the abnormal current levels they create. These currents can produce considerable thermal and mechanical stresses in electrical distribution ...

Settle-out calculations in natural gas systems need to be sufficiently rigorous accurately to predict settle-out under various operating conditions without being so conservative as to increase costs.
