The question of human survival did not often arise in direct form in the strife of the nineteen-sixties, but it was in the air.
Similarly, DSVerifier also implements the filter functions in Direct Form II and Transposed Direct Form II, using the C language and a fixed-point library3.
While the global adjustments in direct form were found significantly effective in improving the prediction of U, they failed to predict the U+ accurately.
When a bounded verification of this system is performed, with implementations in Direct Form I and Transposed Direct Form II structures, the proposed tool issues a counterexample that causes an overflow on an intermediate operation.
On this particular case, the designer intending to implement this filter, in Direct Form I or II, would need to use an accumulator with a higher number of bits for the integer part, two's complement arithmetic, or other technique, when saturation arithmetic is employed, for preventing overflow.
A similar result to the one presented above can be found in [[58], Theorem 2.1] in a direct form of difference inclusions.

The filters were designed using DE for various word lengths, and the same were implemented in transposed direct form (TDF) structure.
This information can be obtained either in a direct form, by arterial sampling and the construction of a plasma input function, or in an indirect manner making use of a reference tissue devoid of receptors of interest [10].
Using experimental data, it is shown how the use of models in their direct form allows one to improve process understanding and to predict the product quality from the process settings and grain properties.
A Gesualdo madrigal is heard in a skewed harmonization near the end of the first movement, and again in a more direct form in the finale.
