In page layout, illustration and sculpture, white space is often referred to as negative space.It is the portion of a page left unmarked: margins, gutters, and space between columns, lines of type, graphics, figures, or objects drawn or depicted, and is not necessarily actually white if the background is of a different colour.
The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).
Because it is so quiet, this innermost, or "fiducial" volume is very sensitive to observing WIMP scatters above other backgrounds, and is the space in which LZ's WIMP searches are conducted. Next, the TPC is located inside several layers of active and passive shielding to reduce rates of external gamma rays and neutrons.
1990 – FIRAS on the Cosmic Background Explorer (COBE) satellite measures the black body form of the CMB spectrum with exquisite precision, and shows that the microwave background has a nearly perfect black-body spectrum with T = 2.73 K and thereby strongly constrains the density of the intergalactic medium.
[2] [3] [4] In a composition, the positive space has the more visual weight while the surrounding space - that is less visually important is seen as the negative space. [5] In a two-tone, black-and-white image, a subject is normally depicted in black and the space around it is left blank (white), thereby forming a silhouette of the subject ...
A comparison between a blank passive-matrix display (top) and a blank active-matrix display (bottom). A passive-matrix display can be identified when the blank background is more grey in appearance than the crisper active-matrix display, fog appears on all edges of the screen, and while pictures appear to be fading on the screen.
Another passive collector-distributor Trombe Wall system was built in 1970, in Montmedy, France. The house with 280 cubic metres (9,900 cu ft) living space required 7000 kWh for space heating annually. At Montmedy-between 49° and 50° North latitude-5400 kWh were supplied by solar heating and the remainder from an auxiliary electrical system.
Both active and passive strategies are involved. The use of flexible thin-film photovoltaic modules provides fluid integration with steel roofing profiles, enhancing the building's design. Orienting a building to the sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally ...
