Armstrong Hydroelectric Machine. The Armstrong effect is the physical process by which static electricity is produced by the friction of a fluid. It was first discovered in 1840 when an electrical spark resulted from water droplets being swept out by escaping steam from a boiler.
Franklin's electrostatic machine on display at the Franklin Institute. Franklin's electrostatic machine is a high-voltage static electricity-generating device used by Benjamin Franklin in the mid-18th century for research into electrical phenomena.
Static application security testing (Static Code Analysis) tool Online Semgrep: 2025-02-27 (1.110.0) Yes; LGPL v2.1 — — Java JavaScript, TypeScript — Python Go, JSON, PHP, Ruby, language-agnostic mode A static analysis tool that helps expressing code standards and surfacing bugs early. It also has experimental support for eleven other ...
A growing commercial use of static analysis is in the verification of properties of software used in safety-critical computer systems and locating potentially vulnerable code. [5] For example, the following industries have identified the use of static code analysis as a means of improving the quality of increasingly sophisticated and complex ...
Ann Arbor is a city in and the county seat of Washtenaw County in the U.S. state of Michigan.Founded in 1824 by John Allen and Elisha Rumsey, it was named after the wives of the village's founders, both named Ann, and the stands of bur oak trees they found there.
Due to Earnshaw's theorem, no static arrangement of classical electrostatic fields can be used to stably levitate a point charge. There is an equilibrium point where the two fields cancel, but it is an unstable equilibrium. By using feedback techniques it is possible to adjust the charges to achieve a quasi static levitation.
Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
