In a sense, they were patenting an abstraction, a mathematical formula; but to implement the formula requires some software, and software is patentable.
In turn, the French procedure for capacity calculations at roundabouts is based on the exponential regression technique [12]; in this case, it is necessary to determine some geometric values of the roundabout and to use a pre-fixed value of the follow-up headway to implement the formula.
However, it seems to the authors that, during the last decades, the computation for a given Miller index h of and its gradient with respect to crystallographic parameters has very rarely been presented in all the minute details necessary to implement those formulae in a program, justifying this appendix in our humble opinion.
Well-defined routines help implement the formulae.
Ball implemented the formula method to simplify the calculations of process lethality by generating charts and tables that correlate the temperature profile of the food product with microbial inactivation kinetics data.
Starting and less skilled unit actors primarily find support in starting up their units or implementing the formula helpful for realizing positive results.
Confidence limits of PAFs were calculated by using the command aflogit, which implemented the formulas proposed by Greenland and Drescher (46).
In a second time we show how to implement a formula designed to compute duty cycle in pulse width modulation control (PWM), in spite of not perfect MCB model and no linear PV module behavior.
The partner schools have spent the current school year looking at how to implement the new formula, Belvin says, and it is scheduled to go into effect in 2003-2004.
The mean period of follow-up among seroconverters in our study was 1.4 years; we thus used estimates of σ (0.7680) and ε1 (0.2770) from another study in order to implement the McDougal formula [6] (compare also [10]).
