All electrical systems are susceptible to short circuits and the abnormal current levels they create. These currents can produce considerable thermal and mechanical stresses in electrical distribution ...

Future events such as the weather or satellite trajectories are computed in tiny time steps, so the computation must be both efficient and as accurate as possible at each step lest errors pile up. A ...

The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...

In a direct comparison study, researchers have added to evidence that a newer method of calculating so-called 'bad cholesterol' levels in the blood is more accurate than the older method in people who ...

Settle-out calculations in natural gas systems need to be sufficiently rigorous accurately to predict settle-out under various operating conditions without being so conservative as to increase costs.

Currently, there is no precise computation method to describe superconducting materials. Scientists have now made a major advance towards achieving this goal and, at the same time, has furthered an ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Eric's career includes extensive work in ...
