The asymmetric unit of the title compound, C(10)H(24)N(3) (+)·0.5C(4)H(2)O(4) (2-)·0.5C(4)H(4)O(4), comprises a triisopropyl-guanidinium cation, half of a fumarate dianion and half of a fumaric acid mol-ecule; both the fumarate dianion and the fumaric acid mol-ecule are located on inversion centres. In the crystal, inter-molecular O-H⋯O hydrogen bonds between the carboxyl groups of the fumaric ...

In the phospho-ric triamide mol-ecule of the title compound, C(6)H(14)N(+)·C(2)H(3)O(2) (-)·C(18)H(36)N(3)OP, the P atom displays a distorted tetra-hedral geometry and the cyclo-hexyl rings adopt chair conformations with the NH groups in equatorial positions. In the crystal, the cations, anions and phosphoric triamide mol-ecules are linked via N-H⋯O hydrogen bonds into a two-dimensional array p...

Residue Number System is a numerical system which arithmetic operations are performed parallelly. One of the main factors that affects the system’s performance is the complexity of reverse converter. It should be noted that the complexity of this part should not affect the earned speed of parallelly performed arithmetic unit. Therefore in this paper a high speed converter for moduli set {2n-1, ...
