Arc flash - Wikipedia

★ ★ ★ ☆ ☆

An arc flash (also called a flashover) is the light and heat produced as part of an arc fault, a type of electrical explosion or discharge that results from a low-impedance connection through air to ground or another voltage phase in an electrical system.. Arc flash is distinctly different from the arc blast, which is the supersonic shockwave produced when the uncontrolled arc vaporizes the ...

The flash grab effect - ScienceDirect

★ ★ ★ ☆ ☆

10/18/2013 · We now add a new effect to this family of motion-induced position shifts that we call the flash grab effect. It has two components. The first generates the position shift and is specific to the end points of a motion trajectory when a texture or an object undergoes repeated back-and-forth motions.

Welding - Wikipedia

★ ★ ★ ★ ★

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.. In addition to melting the base metal, a filler material is typically ...

The contrast invariance of the effect beyond 5% is similar in producing the position shift, but the contrast step localized at or near the flash. The low frequency sine wave presents only a grad- ual contrast gradient at its midpoint whereas the square wave pre- sents the same contrast step at the flash location at all frequencies.
