Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge [ 1 ] or partial discharge , [ 2 ] it was first reported by Ernst Werner von Siemens in 1857.
The stacking factor (also lamination factor or space factor [1]) is a measure used in electrical transformer design and some other electrical machines. It is the ratio of the effective cross-sectional area of the transformer core to the physical cross-sectional area of the transformer core. The two are different because of the way cores are ...
From the gain factor G, one finds the gain in decibels as: G dBi = 10 log 10 ( G ) . {\displaystyle G_{\text{dBi}}=10\log _{10}\left(G\right).} Therefore, an antenna with a peak power gain of 5 would be said to have a gain of 7 dBi. dBi is used rather than just dB to emphasize that this is the gain according to the basic definition, in ...
X-ray atomic form factors of oxygen (blue), chlorine (green), Cl − (magenta), and K + (red); smaller charge distributions have a wider form factor. In physics, the atomic form factor, or atomic scattering factor, is a measure of the scattering amplitude of a wave by an isolated atom. The atomic form factor depends on the type of scattering ...

Novak Djokovic declined to do a customary post-match TV interview at the Australian Open after his win Sunday night to protest comments made on air by someone who works for the official ...
Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...
