Zuckerberg's business model requires the trust and loyalty of his users so that he can make money from their participation, yet he must simultaneously stretch that trust by driving the site to maximize profits, including by selling users' personal information.
The model requires the parallel evaluation of solution elements.
The experimental verification of this model requires the availability of stable, non-aggregated, colloidal nanoparticle suspensions.
It is necessary to indicate that the model requires the big M.
In a dry powder, this model requires the making and breaking of interparticle contacts.
This type of model requires the assumption of a certain error distribution, which can be challenging.
The model requires the experimental determination of a geometric parameter and of the heat transfer coefficients.
The model requires the knowledge of the static modulus of elasticity, the compressive strength and the peak strain εc1.
A best practice model requires the combination of elaborate pre-processing, 2D as well as 3D active contours.
This, much like the 2-tier model, requires the recomputation of the schedule when sub-tree membership changes.
The non-uniform flow model requires the velocity of the current at any point and any time in the domain.
