NEAT has a cooperative agreement with the U. S. Air Force to use a GEODSS telescope located on Haleakala, Maui, Hawaii.

A mobile telescope that contributes to the GEODSS system is located at Morón Air Base, Spain

Originally, the fifth GEODSS was planned to be operated from a site in Portugal, but this was never built.

GEODSS tracks objects in deep space, or from about 3, 000 mi ( 4, 800 km ) out to beyond geosynchronous altitudes.

GEODSS requires nighttime and clear weather tracking because of the inherent limitations of an optical system.

GEODSS system can track objects as small as a basketball more than 20, 000 miles ( 30, 000 km ) in space or a chair at, and is a vital part of USSTRATCOM ’ s Space Surveillance Network.

Each GEODSS site tracks approximately 3, 000 objects per night out of 9, 900 object that are regularly tracked and accounted for.

Presently it is called A-135 and it uses two missile types, Gorgon and Gazelle.

There are only two specific exercises practiced separately ; the first is lying semi-supine ; resting in this way uses " mechanical advantage " as a means of releasing cumulative muscular tension.

The general Amiga architecture uses two distinct bus subsystems, namely, the chipset bus and the CPU bus.

Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.

As the world quickly moved to IP for both LAN and WAN uses, Apple was faced with maintaining two increasingly outdated code bases on an ever-wider group of machines as well as the introduction of the PowerPC based machines.

Religious use in Brazil was legalized after two official inquiries into the tea in the mid-1980s, which concluded that ayahuasca is not a recreational drug and has valid spiritual uses.

ATM uses a connection-oriented model in which a virtual circuit must be established between two endpoints before the actual data exchange begins.

The modern form of this instrument was developed by Edward Weston, and uses two spiral springs to provide the restoring force.

Tradition ( e. g. Donald Knuth's ( 1973 ) hypothetical MIX computer ), for example, uses two instructions called load accumulator from register / memory ( e. g. " LDA r ") and store accumulator to register / memory ( e. g. " STA r ").

Natural boron is composed of two stable isotopes, one of which ( boron-10 ) has a number of uses as a neutron-capturing agent.

The computer industry uses terms such as kilobyte, megabyte, and gigabyte, and corresponding symbols KB, MB, and GB, in two different ways.

The brainfuck language uses a simple machine model consisting of the program and instruction pointer, as well as an array of at least 30, 000 byte cells initialized to zero ; a movable data pointer ( initialized to point to the leftmost byte of the array ); and two streams of bytes for input and output ( most often connected to a keyboard and a monitor respectively, and using the ASCII character encoding ).

Due to the costs involved in owning, operating and driving buses and coaches, many bus and coach uses a private hire of vehicles from charter bus companies, either for a day or two, or a longer contract basis, where the charter company provides the vehicles and qualified drivers.

The area of research within computer science that uses genetic algorithms is sometimes confused with computational evolutionary biology, but the two areas are not necessarily related.

The Norwegian all-girl pop band Katzenjammer uses two contrabass balalaikas, both of which have cat faces painted on the front.

* In the 2011 version of " Hunter x hunter ", Kurapika Kuruta uses a two bokken swords.

To execute an instruction in a computer program, the CPU uses the opcode for that instruction as well as its arguments ( for instance the two numbers to be added, in the case of an addition operation ).

Musician Alan Stivell uses a similar dichotomy, between the Gaelic ( Irish / Scottish / Manx ) and the Brythonic ( Breton / Welsh / Cornish ) branches, which differentiate " mostly by the extended range ( sometimes more than two octaves ) of Irish and Scottish melodies and the closed range of Breton and Welsh melodies ( often reduced to a half-octave ), and by the frequent use of the pure pentatonic scale in Gaelic music.

In general, the three-letter code uses the ISO 3166-1 country code for the first two letters and the first letter of the name of the currency ( D for dollar, for instance ) as the third letter.

* In Iliad 9. 165-93 three characters, Phoinix, Odysseus, and Aias set out on an embassy to Achilleus ; however, at line 182 the poet uses a verb in the dual form to indicate that there are only two people going ; at lines 185ff.

Another simulation uses illumination plotted from a radiosity algorithm, or a combination of these two.

To draw this image the computer uses math to calculate how to project this image, defined by three dimensional data, onto a two dimensional computer screen.

For example, PAL-M ( Brazil ) uses a 3. 58 MHz subcarrier, and SECAM uses two different frequencies, 4. 250 MHz and 4. 40625 MHz above the video carrier.

Other uses are in imaging systems such as monoculars, binoculars, telescopes, microscopes, cameras and projectors.

LINEAR uses two one-meter telescopes and one half-meter telescope based in New Mexico.

The Very Long Baseline Array ( VLBA ) uses ten dedicated, 25-meter telescopes spanning 5351 miles across the United States, and is the largest VLBI array that operates all year round as both an astronomical and geodesy instrument.

A mid-20th century innovation was catadioptric telescopes such as the Schmidt camera, which uses both a lens ( corrector plate ) and mirror as primary optical elements, mainly used for wide field imaging without spherical aberration.

He nevertheless uses his remaining hand to work wonders when polishing high quality lenses and mirrors for astronomical telescopes.

The DEEP2 Redshift Survey uses the Keck telescopes with the new " DEIMOS " spectrograph ; a follow-up to the pilot program DEEP1, DEEP2 is designed to measure faint galaxies with redshifts 0. 7 and above, and it is therefore planned to provide a complement to SDSS and 2dF.

COAST, the Cambridge Optical Aperture Synthesis Telescope, is a multi-element optical astronomical interferometer with baselines of up to 100 metres, which uses aperture synthesis to observe stars with angular resolution as high as one thousandth of one arcsecond ( producing images with much higher resolution than can be obtained using individual telescopes such as the Hubble Space Telescope ).
