4Salisbury screen — The Salisbury screen is maybe the first ever anti radar or, to be more precise, anti reflective concept; the so called RAM (radar absorbent material). It was first described in 1952 and was applied in ship radar cross section reduction (RCS).… …
5Transformer — This article is about the electrical device. For the toy line franchise, see Transformers. For other uses, see Transformer (disambiguation). Pole mounted distribution transformer with center tapped secondary winding. This type of transformer is… …
6Remote sensing — There are two kinds of remote sensing. Passive sensors detect natural energy (radiation) that is emitted or reflected by the object or surrounding area being observed. Reflected sunlight is the most common source of radiation measured by passive… …
7Z-buffering — Z buffer data In computer graphics, z buffering is the management of image depth coordinates in three dimensional (3 D) graphics, usually done in hardware, sometimes in software. It is one solution to the visibility problem, which is the problem… …
8Surround sound — Surround sound, using multichannel audio, encompasses a range of techniques for enriching (expanding and deepening) the sound reproduction quality, of an audio source, with additional audio channels reproduced via additional, discrete speakers.… …
