This was replaced by the "management by objectives" model, which allowed for more autonomy.
It later shifted to the membership model, which allowed customers to find unused seats on nearby jets.
Its metered model, which allowed eight free items to be read each week, was relatively easy to circumvent (by clearing cookies, lest you didn't know).
The evolution of dispersal was investigated in an adaptive individual-based metapopulation model, which allowed for demographic and environmental stochasticity.
"People were paying about $1 a month for kerosene lamps, so we had to have an economic model which allowed people to pay about the same as they did before.
The RAND poll LV model, which allowed voters to assign themselves a percentage likelihood of voting, had Obama leading by 3.3 points and was only 0.4 points off the mark.
The measured surface topography was incorporated into a finite element model, which allowed simulating the indentation of an axisymmetric sample by a rigid spherical indenter.
Gas permeabilities of multilayered films were compared to control PEBAX films using a simple model, which allowed inferences about the completeness of pore formation to be drawn.
Experimental results were used to validate a simplified mono-dimensional model which allowed simulating more severe conditions and different protection configurations.
The results from the experimental tests have been compared with predictions obtained by applying a micro-mechanical model, which allowed taking into account the fibre length distribution and the properties of the phases of the composite.
This alternative model, which allowed statistical flexibility in estimating effect direction and strength, correctly predicted ordinal degradation class at 54% of field sites, with 55% sensitivity for the severe degradation class.
