  1. Tolerance Erik Frey

  2. Principle Ideas • The Universe isn’t static. • The strongest materials have the ability to give. • Tolerance wins over strict rigidity.

  3. Solid foundation structures aren’t always best. Pre-cast Concrete Panels work fine in low earthquake areas.

  4. Ground Movement Tolerance A technique for compensation of movement in high earthquake areas.

  5. What have we learned from the past? Heart Pillar: Ancient Japanese design using free floating floors surrounding a center post that will sway and give way during an earthquake.

  6. Tolerance of .005in. Bearing Crankshaft In engines the tolerances are incredibly precise. During normal operation, the crankshaft doesn’t touch the bearing. Housing

  7. Hardware RAIDFault Tolerance In this instance we see the compensation for the loss of a hard drive in a computer.

  8. Software RAID A simple software mirror can save your data in the event of failure.

  9. Summary • Designing a system the can remain reliable with error is most desirable. • Simple redundancy can mean the difference between annoyance and • disaster. • Proper tolerance in machines can lead to long life and reliability. • Entropy occurs at the sub-atomic level, nothing in the universe • stays static, and the ability to adapt or absorb remains advantageous.

  10. End
