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.
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.
Confidence limits of PAFs were calculated by using the command aflogit, which implemented the formulas proposed by Greenland and Drescher (46).
Starting and less skilled unit actors primarily find support in starting up their units or implementing the formula helpful for realizing positive results.
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]).
At the design level of the programme however, one of the main assumptions made, namely the commitment of the FGN to implement the agreed cost sharing formula and to elaborate rresponding administrative and disbursement procedures did not yet materialise; this has created serious delays in the programme implementation.
Furthermore, implementing the integral formula [38]: (5.3).
We have implemented the following formula for the number of citations.
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.
