Linear Elamite, a writing system used in what is now Iran, may reveal the secrets of a little-known kingdom bordering Sumer ...

The linear electric machine-based gravity energy storage system (LEM-GESS) uses linear machines to vertically move multiple solid masses, or pistons, to store and discharge electrical energy.

In a thermally linear system, superposition may be applied to predict the transient response of the system to step changes in input power. This article is the second in a two-part series.
