* AX series – Extreme version of the artist model, aimed towards metal players – currently only exist as GAX model and Guitar Center exclusive model.

AX Microscopii, better known as Lacaille 8760, is a red dwarf which lies only 12. 9 light years from our solar system.

Packets radio use the AX. 25 ( Amateur X. 25 ) data link layer protocol, derived from the X. 25 protocol suite and adapted for amateur radio use.

AX. 25 includes a digipeater field to allow other stations to automatically repeat packets to extend the range of transmitters.

A variant called AX. 25 is also used widely by amateur packet radio.

However, since 7s shell completely does not participate, the VSEPR-predicted structure would be trigonal pyramidal ( AX < sub > 3 </ sub > E < sub > 1 </ sub >); UusF < sub > 3 </ sub > has, however, this structure not energetically favored, picking instead the trigonal planar structure ( corresponding to a formula of AX < sub > 3 </ sub >) up.

Freiling's axiom of symmetry ( AX ) is a set-theoretic axiom proposed by Chris Freiling.

The axiom AX is now justified based on the principle that what will predictably happen every time this experiment is performed, should at the very least be possible.

In fact, a given n-by-n matrix A is similar to a diagonal matrix ( meaning that there is a matrix X such that X < sup >- 1 </ sup > AX is diagonal ) if and only if it has n linearly independent eigenvectors.

Two variable stars are Theta Circini, an irregular variable ranging from apparent magnitude 5. 0 to 5. 4, and AX Circini, a Cepheid Variable which ranges from 5. 6 to 6. 19 over 5. 3 days.

It was repeated by Michele Marelli on 25 January 2002 in Alessandria ( Italy ) for the Jazz Association " L ' AX ".

AX. 25 is a data link layer protocol derived from the X. 25 protocol suite and designed for use by amateur radio operators.

AX. 25 occupies the first, second, and often the third layers of the OSI networking model, and is responsible for transferring data ( encapsulated in packets ) between nodes and detecting errors introduced by the communications channel.

AX. 25 is thus comparable to the combination of Ethernet and TCP in the services it provides.

However, as AX. 25 is a pre-OSI-model protocol, the specification was not written to cleanly separate into OSI layers.

In practice, it is not uncommon to find an AX. 25 data link layer as the transport for some other network layer, such as IPv4, with TCP used on top of that.

Note that, like Ethernet, AX. 25 frames are not engineered to support switching.

For this reason, AX. 25 supports a somewhat limited form of source routing.

Although possible to build AX. 25 switches in a manner not unlike how Ethernet switches work, this has not yet been accomplished.

AX. 25 supports both virtual-circuit connected and datagram-style connectionless modes of operation.

Traditionally, amateur radio operators have connected to AX. 25 networks through the use of a terminal node controller, which contains a microprocessor and an implementation of the protocol in firmware.

More recently, AX. 25 implementations have appeared for personal computers.

For example, the Linux kernel includes native support for AX. 25 networking.

the use of additional network layers with AX. 25 is impractical due to the data overhead involved.

This is not a limitation of AX. 25 per se, but places constraints on the sophistication of applications designed to use it.

The AX. 25 protocol identifies each message by sender and destination station call-sign plus SSID value

However AX. 25 has a built in hard limit

It was a substantial development of the Citroën AX platform, intended to make it both heavier and safer.

It shares many engine and body parts with the Peugeot 106 ( which itself was a development of the Citroën AX ), the major difference being interiors and body panels.

The equipment list was generally sparse, with budget models having drivers air bag, seat belt pre-tensioners, cassette player, heated rear screen and tinted windows, and early mk1's with keypad immobilisers and a clock in place of a tachometer and 3 stud wheels, much like the AX.

When Nissan ended Nissan Pintara manufacturing in Australia during 1992, Ford's Corsair was dropped and the Telstar ( AX ), fully imported from Japan, once again became Ford's offering in the mid-size segment of the market.

The AX was launched at the 1986 Paris Motor Show to replace the Citroën Visa and Citroën LNA.

Development of this model started in 1983, and was initially also going to form the basis of a sister model from Talbot to replace the Samba ; however, the falling popularity of the Talbot brand had led to Peugeot deciding to axe it by the time the Citroën AX was launched, and so the Talbot version never made it into production.

The first performance version was the limited-run AX Sport from 1987, with a 1. 3 engine and twin carburettors producing, wearing iconic white steel wheels ( 5, 5 " x 14 ") which resembled those on its brother, the Peugeot 205 Rallye.

The AX Sport used Solex ADDHE 40 carburettors until 1990 and was then replaced with Weber DCOM 40s, just like the 205 Rallye 1, 3.

Later, the AX 14GT, with a single-carburettor 1. 4 engine also found in the Peugeot 205 XS, was introduced.

In January 1995 the Citroën AX Echo was launched, with a top speed of.

It's closest competitor, the Peugeot 106 Ski, ( that shared components with the AX ), was outsold by the Echo.

The range was slimmed-down in 1996, following the introduction of the Saxo, with production of the AX ending in 1998 after a 12 year production run.

The AX was designed for lightness, with a ' less is more ' philosophy, but with more conventional styling than previous Citroëns.

In 1996 the EV3 engine ( air engine ) was mounted into a regular Citroën AX car by MDI.

The Citroën AX BB Cabrio was a small roadster derived from the AX ( 1988 ).

At one stage, parent firm PSA Peugeot Citroën had planned to launch a Talbot Samba replacement as a version of the AX with a different grille and a Talbot badge, but this plan was cancelled, as the entire Talbot marque was axed in the same year the AX was launched.
