The aft part of the hull, while a compromise between good reversing qualities in the ice and low level of propeller-induced vibrations in the stern, is also designed to prevent pieces of ice from coming in contact with the propeller.

Examination of telemetry from the booster indicated that some sort of electrical failure occurred, but subsequent investigation took three months and finally concluded that a switch designed to cut power to the strap-ons at staging had malfunctioned, possibly due to liftoff-induced vibration.

:Rather than an instinct, consciousness appears to be a harmonic relationship that exists due to the complex rhythmic firing of neurons, a sort of music of the brain induced in it by the environment similar to the way one vibrating tuning fork will induce vibration in another.

The validity of certain products are often questioned by those outside the industry include accessories such as speaker wires utilizing exotic materials ( such as Oxygen-Free Copper ( OFC ) ) and construction geometries, cable stands for lifting them off the floor ( as a way to control mechanically induced vibrations ), connectors, sprays and other tweaks.

During her career in NASA, Reaves has been involved in the research on modeling and validation of smart structures, the implementation of probabilistic analysis tools for dynamic model updates, simulation of ground-induced vibration of the HSCT ( High Speed Civil Transport ) as it traversed a typical runway and experiments to determine static and dynamic properties of advanced aircraft tires

She has estimated wind load on many structures including tall buildings, suspension bridges, topsides on offshore platforms, solar plants, etc . Subsequently she has set-up physical models and field experiments, analysed and assessed the structural dynamics and provided solutions to Vortex-induced vibration ( e . g ., Great Belt East Bridge ) and earthquakes.

The losses initially result from impaired heat transfer, corrosion damage ( in particular under-deposit and crevice corrosion ), increased pressure drop, flow blockages, flow redistribution inside components, flow instabilities, induced vibrations ( possibly leading to other problems, e . g ., fatigue ), fretting, premature failure of electrical heating elements, and a large number of other often unanticipated problems.
