Two-level factorial and fractional factorial designs have played a prominent role in the theory and practice of experimental design. Though commonly used in industrial experiments to identify the significant effects, it is often undesirable to perform the trials of a factorial design (or, fractional factorial design) in a completely random order. Instead, restrictions are imposed on the randomi...

The deposition of diamond films by low pressure CVD methods has been demonstrated using a number of thermal and plasma assisted CVD techniques. Addition of oxygen to the methane-hydrogen feedstock has been reported to improve the quality of diamond deposited and decrease the temperature at which diamond deposition is feasible. Oxygen also effects the growth rate and possibly the uniformity of t...
