In a sense, they were patenting an abstraction, a mathematical formula; but to implement the formula requires some software, and software is patentable.
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.
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.
Well-defined routines help implement the formulae.
Confidence limits of PAFs were calculated by using the command aflogit, which implemented the formulas proposed by Greenland and Drescher (46).
Furthermore, implementing the integral formula [38]: (5.3).
At the Institute of Public Health and Nutrition in Dhaka - the government body charged with implementing the curbs on formula manufacturers - director Professor Dr Fatima Parveen Chowdhury is looking askance at several tins of formula milk piled up on her desk.
"The most similar change we did to this was back in 1999, when we first capitalised [included in GDP] computer software," says Brent Moulton, head of national accounts at the BEA and the man tasked with creating and implementing the GDP revision formula.
We have implemented the following formula for the number of citations.
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]).
