Photographs and even the museum's large-scale model fail to do his design justice.

Some critics believe that the 20-70-10 model fails to reflect actual human behavior.

The models didn't fail, not in the way that they had been failing.

But the French model, never updated, has failed, critics say.

This time the model failed to sell, making it extremely rare today.

A model which used a context pattern also failed to increase discrimination between new and old items.

However, the model fails to be effective in manufacturing industry.

We know that our current economic model fails to integrate environmental costs into market prices.

To say that the European model completely failed is totally wrong.

And the new models may fail, despite the industry's excitement.
