Vertical plane — is used in radio to plot an antenna s relative field strength perpendicular to the ground (which directly affects a station s coverage area) on a polar graph. Normally the maximum of 1.000 or 0 dB is at the side (unless there is beam tilt), which … Wikipedia
Field hockey stick — In Field hockey, each player carries a stick and cannot take part in the game without it. The stick is usually between 36 and 38 long (but this is not defined or restricted)and traditionally made of wood but now almost all the more expensive… … Wikipedia
Vertical jump — A vertical jump or vertical leap is the act of raising one s center of gravity higher in the vertical plane solely with the use of one s own muscles; it is a measure of how high an individual or athlete can elevate off the ground (jump) from a… … Wikipedia
geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… … Universalium
Earth's magnetic field — Computer simulation of the Earth s field in a normal period between reversals.[1] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and… … Wikipedia
Near and far field — This article is about the electromagnetic concept. For the mathematical, see Near field (mathematics). Antenna field regions for antennas that are shorter than the wavelength of the radiation they emit, such as the whip antenna of a citizen s… … Wikipedia
Decision field theory — (DFT), is a dynamic cognitive approach to human decision making. It is a cognitive model that describes how people make decisions rather than a rational model that prescribes what people should do. It is also a dynamic model of decision making… … Wikipedia
Near Vertical Incidence Skywave — An NVIS antenna configuration is a horizontally polarized radiating element. Near Vertical Incidence Skywave, or NVIS, is a radio wave propagation method that provides usable signals in the range between groundwave and skywave distances (usually… … Wikipedia
