WebJun 22, 2024 · The “optimally oriented flux” filter, first published in [ 10 ], evaluates a scalar measure of the flux flowing through a spherical surface. Before computing this value, directional information is extracted by projecting the gradient along “optimal” axes, and the flux measure then evaluated. WebSmart, Data oriented, computable and self-driving contracts. An overview. In this essay, we try to map the international debate about the evolution of concept of contract and his link with the new technologies.
