	Diameter - Wikipedia, the free encyclopedia
		In geometry, a diameter (Greek words diairo = divide and metro = measure) of a circle is any straight line segment that passes through the center and whose endpoints are on the circular boundary, or, in more modern usage, the length of such a line segment.
		The diameter of a subset of a metric space is the least upper bound of the distances between pairs of points in the subset.
		Diameter is also sometimes called phi (pronounced the same as "fie"), although this seems to come from the fact that Ø and ø look like Φ and φ, the letter phi in the Greek alphabet.

	Conversion of Absolute Magnitude to Diameter (Site not responding. Last check: )
		The following table lists the diameters of minor planets corresponding to the given values of the absolute magnitude, H. The diameter is to be read as kilometers when H is in the left-hand column or as meters when in the right-hand column.
		E.g., for a rocky body, H = 8.0 corresponds to a probable diameter range of 65 to 150 km, whereas H = 23.0 corresponds to a probable diameter range of 65 to 150 m.
		This quantity is not known for most objects, so the diameters listed here are given as ranges: the smallest value corresponding to an albedo of 0.5 (intended for icy object), the middle value corresponding to an albedo of 0.25 and the larger to an albedo of 0.05.

	Diameter \| World of Mathematics
		A diameter is a straight-line segment that passes through the center of a circle or sphere and whose two end points lie on the circumference of the surface.
		Diameter is an appropriate name for the measure across a circle or sphere, as the word is the union of the Greek roots "dia" (across) and "metros" (to measure).
		The history of diameter is rooted in the attempts by the ancient Greeks to find an exact ratio for a value of pi, that of circumference over diameter (C / d).

	Introduction to Diameter
		The Diameter protocol was derived from the RADIUS protocol with a lot of improvements in different aspects, and is generally believed to be the next generation Authentication, Authorization, and Accounting (AAA) protocol.
		Diameter is designed as a Peer-To-Peer architecture, and every host who implements the Diameter protocol can act as either a client or a server depending on network deployment.
		Diameter protocol explicitly defines that a Diameter node must establish a connection with two peers per realm at a minimum, which act as primary and secondary contacts.

	DIAMETER (Site not responding. Last check: )
		The Diameter base protocol is intended to provide an Authentication, Authorization and Accounting (AAA) framework for applications such as network access or IP mobility.
		Diameter agents only need to be concerned about the number of requests they send based on a single received request; retransmissions by other entities need not be tracked.
		Diameter makes use of the realm, also loosely referred to as domain, to determine whether messages can be satisfied locally, or whether they must be routed or redirected.

	Outside diameter finishing tool and method of making the same - Patent 6080053
		The grindstones each have identical centers of curvature of a desired diameter and are placed adjacent one another to form a circular grinding surface with a diameter substantially equal to that of the piston rings.
		The diameter of the circular grinding surface is adjustable by either pinion/scroll means or a wedgeshaped adjuster, both of which adjust the radial position of the grindstone elements.
		It is an object of the present invention to provide an outside diameter finishing tool using superabrasives to cut simultaneously around the full periphery of a generally cylindrical workpiece while the workpiece or tool freely passes through or over the other.

	Device for controlling at least one throttle diameter in a control line - Patent 4428356
		A device for the control of at least one throttle diameter in a control line, especially in a line carrying fuel for an internal combustion engine, is proposed.
		In contrast to the foregoing, the device in accordance with the present invention has the advantage that a flow of the fuel during the closed state of the device is rendered completely impossible, while at the same time the device is kept dirt-free by virtue of its unique construction.
		During a turn of the control section 37 counterclockwise in order to open the throttle diameter to a larger or lesser degree, the radial distances between the circumference 42 of the control section 37 and the sealing surface 40 constantly increases.

	Terrestrial Impact Craters
		The diameter at which craters become complex depends on the surface gravity of the planet: The greater the gravity, the smaller the diameter that will produce a complex structure.
		On Earth, this transition diameter is 2 to 4 kilometers (1.2 to 2.5 miles) depending on target rock properties; on the Moon, at one-sixth Earth's gravity, the transition diameter is 15 to 20 kilometers (9 to 12 miles).
		The circular shoreline, at a diameter of 11 kilometers (6.8 miles), is partially surrounded by a ridge with heights to 100 meters (328 feet) above the lake surface.

	5. Large diameter wells
		As the diameter is increased, certain practical limits are reached, however, since the volume of excavated material is proportional to the square of the diameter and the volume of material necessary to line the excavation is roughly proportional to the diameter.
		The line may be attached to a special gauge stick with a hole near each end which lies along a diameter of the well at the ground surface and indexes over two steel rods securely driven into the ground on either side of the well (Figure 44a).
		When the water in large diameter wells is drawn down considerably below its static level the pressure exerted on the material at the bottom of the well by the water in the well may be appreciably less than the pressure exerted on it by the water surrounding the well.

	Large 17' diameter wind turbine
		The steel rotors for the alternator are 16" in diameter, cut from 1/2" thick steel.
		The diameter of the stator will be 20", so the diameter of the stator brackets is also 20".
		I made a simple 'jig' 20" in diameter, and drilled the 6 holes in it - and a center hole that fits over the wheel spindle, (basically a blank stator) and then we bolt the stator brackets to the jig.

	Charon's Diameter, Redux - The Planetary Society Blog \| The Planetary Society
		When I went to DPS last year I reported on a new diameter for Charon that had been calculated based upon careful measurements performed during a stellar occultation by Charon on July 10-11, 2005.
		That new diameter came from a talk given by Bruno Sicardy and was 1,205 +/- 2 kilometers.
		That is to say, Sicardy's measurements pinpoint the actual diameter to be somewhere between 1,204.4 and 1,210.0 kilometers.

	SEINIT Portal - DIAMETER
		DIAMETER is recognised as a peer to peer protocol since any node is free to initiate a request at any time.
		DIAMETER is also meant to operate both with local and with roaming situations.
		Since DIAMETER is not a complete protocol by itself, but it needs application-specific extensions from the technology, or architecture, used to access the network, it is not possible to describe or compare the protocol’s details regarding security and other aspects.

	Internet accounting - Diameter
		A DIAMETER extension is an extension on the described protocol for a specific service or task using DIAMETER as a transport mechanism.
		This protocol introduces a ZLB message (Zero Length Body, a diameter message without a diameter command), which is used to send an acknowledge of a received message, when there is no other message to piggy-back the the acknowledgement.
		Diameter supports Keep-allive messages and messages that indicate that a server is going down for a time period.

	Effects of wire diameter and spacing
		In practice, however, one of the most common types of variation from cable to cable is in the choice of the diameters of the wires, and the spacing between them.
		Since the wire diameter is the same for all the lines shown in figure 11 they all have the same value of wire internal impedance.
		If so, the general advice would seem to be to choose reasonable large diameter wires with a close spacing in order to minimise the effects of resistance and inductance.

	SEINIT Portal - DIAMETER
		A DIAMETER Client is a device at the edge of the network that performs access control, usually referred to as Network Access Server (NAS) or Foreign Agent (FA).
		It is important to highlight that a DIAMETER node could be acting as a Server for certain requests while acting as an Agent for others.
		DIAMETER requires that Agents maintain transaction state, meaning that upon forwarding a request, the original hop-by-hop identifier of the message is saved for failover purposes.
