The language supports the specification of hard real-time systems with reusable components from domain specific component libraries.
Based on these data provided on standard hard gelatin capsules, product-specific or customized specifications and variability of hard gelatin capsules can be defined.
This approach, when further elaborated for discrete-event systems represented by formal languages, turns out to impose a hard lower-bound inclusion specification on the closed-loop behaviour.
It is evidently hard to think of chemical specifications of the property of being a predator, or neurological specifications of the generic state of desiring to eat ice cream, but the problem arises even in more tractable cases, such as that of providing chemical conditions for being a gene.
But if the mixture sits in the drum of a truck longer than 90 minutes, it becomes too soft or too hard and fails to meet specifications.
Until someone invents a "universal replicator" capable of synthesising any object from software specifications, it is hard to see how the open-source model can be applied to manufactured goods.The model has other limitations as well.
The hard constraints include the hardware specifications and advertised/observed reliability, as well as the software configuration, such as the operating system type associated with it.
However, the lack of standardized techniques and specifications makes it hard to integrate complex systems, especially when developed by different subjects.
We had a hard time in following the specifications: two beam lines with a resolving power larger than 250 requiring only a 15 mass difference between both simultaneous beams.
However, in practice, it can be challenging to run these algorithms in a researcher's own laboratory, owing to the requirements of third-party software and databases, and large hard disk space and RAM specifications.
