The characterization of reservoirs has evolved, during the past 15 or so years, from a simple engineering evaluation, to multidisciplinary teams of geologists, geophysicists, petrophysicists, and petroleum engineers working together.
A theoretical expression of thermal performance factor has been derived in this paper for simple engineering evaluation of different cooling channel designs with asymmetric heating, intended for regenerative engine cooling applications in the aerospace propulsion and power-generation systems.
"We don't know why the mistake was made, it's a simple engineering problem.
But his simple engineering helped expose the Volkswagen emissions cheating scandal, which has thrown the German car maker into the worst crisis in its 69-year history.
Consider, as counterpoint to Mr. Petroski, two simple engineering triumphs from widely contrasting eras, each of which has enjoyed considerable popularity.
(In fact, a few weeks after my visit to CERN, during a test of a set of magnets known as an "inner triplet," a support failed, bursting a pipe and spewing helium into the tunnel. The failure of the support, which was produced in the United States, was attributed to a simple engineering error).
Some of these are in simple engineering: Shimano earns around $1.5 billion a year by supplying 60-70% of the world's bicycle gears and brakes; YKK makes around half the world's zip fasteners by value, and used to control far more.
Simple engineering analyses that estimate bone strength may yield overly optimistic results, a new study suggests.
Simple engineering constraints have a lot to do with it: Rolling on wheels is energy efficient; flying through the air isn't.
Finally, the modified coefficient iterative algorithm is presented for the simple engineering application.
These properties yield a simple engineering product-form approximating tightly the minimum response time.
