The construction of central map transformation depends on a map with the following representation.
After that, the result of central map transformation F, i.e., ( xleft({overline{x}}_0,{overline{x}}_1,dots, {overline{x}}_{27}right) ) is computed.
During central map transformation in signature generations, it is required to solve LSEs in a finite field twice with the same matrix size 9 × 9.
We suppose that ( xleft({overline{x}}_0,{overline{x}}_1,dots, {overline{x}}_{27}right) ) denote the result of central map transformation F, where ( {overline{x}}_0,{overline{x}}_1,dots, {overline{x}}_{27} ) are elements in GF((24 2).
His central interest was transformation, the alchemy of one thing turning into another.
An open, resilient global financial system will be central to the transformation of the global economy.
"Pygmalion" is not strictly a fashion play, though a mastery of fashion is central to the transformation of Eliza Doolittle from a Cockney flower girl to an Edwardian lady.
The Army's most senior general has complained that "misinformation" is damaging prospects for the Stryker, a light armored vehicle that the service argues is central to its transformation into a more mobile fighting force.
