Consequently they proposed a new system for Africa, the Three-stage System.

Clark regarded the Three-age System as valid for North Africa ; in sub-Saharan Africa, the Three-stage System was best.

There are in effect two Stone Ages, one part of the Three-age and the other constituting the Three-stage.

Volume 1 ( ( Af ) of the seventh edition of Dana's System Of Mineralogy was published in 1944 and Volume 2 ( ( Af ) in 1951 by John Wiley & Sons, Inc., New York, N. Y..

This fiery swath was actually only a belt of minor planets, almost like the asteroid belt in the original Solar System.

These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.

Just under five hours later, on the CSM's 65th orbit around the Moon, its Service Propulsion System main engine was reignited to propel the craft on a trajectory that would return it to Earth.

* Attached Support Processor, one of the two early IBM System / 360 programs that replaces the native SPOOL facilities of OS / 360 ; the other was Houston Automatic Spooling Priority ( HASP ).

AIX Version 1, introduced in 1986 for the IBM 6150 RT workstation, was based on UNIX System V Releases 1 and 2.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

AIX / 370 was IBM's third attempt to offer Unix-like functionality for their mainframe line, specifically the System / 370 ( the prior versions were a TSS / 370 based Unix system developed jointly with AT & T c. 1980, and VM / IX a VM / 370 based system developed jointly with Interactive Systems Corporation c. 1984 ).

AIX / 370 was released in 1990 with functional equivalence to System V Release 2 and 4. 3BSD as well as IBM enhancements.

With the introduction of the ESA / 390 architecture, AIX / 370 was replaced by AIX / ESA in 1991, which was based on OSF / 1, and also ran on the System / 390 platform.

* A very High resolution monochrome video card with blitter and hardware text line and arc drawing capability, was designed for CAD applications, based on the NEC µPD7220 chip designed for graphic terminals, but was also used by some personal computers like the DEC Rainbow, and notably also for the Tulip System I.

In its prototype stage, the Atari 5200 was originally called the " Atari Video System X-Advanced Video Computer System ", and was codenamed " Pam " after a female employee at Atari Inc.

In January 1986, the 7800 was again released and would compete that year with the Nintendo Entertainment System and the Sega Master System.

Powering the system was an Atari SALLY 6502 ( Atari's slightly custom 6502, sometimes described as a " 6502C ") processor running at 1. 79 MHz, similar to the processor found in home computers ( Atari 8-bit, Apple II, Commodore 64 ) and other consoles ( Atari 5200 and Nintendo Entertainment System ).

Despite trailing the Nintendo Entertainment System in terms of number of units sold, the 7800 was a profitable enterprise for Atari Corp., benefiting largely from Atari ’ s name and the system's 2600 compatibility.

The most notable exception was the XG-1 lightgun, which came bundled with the Atari XE Game System.

Released on the XE Game System, an Atari 7800 version was started but not completed beyond a simple demo.

Atari Corp. then showed the Lynx to the press at the Summer 1989 CES as the " Portable Color Entertainment System ", which was changed to Lynx when actual consoles were distributed to resellers.

... was also a great and profound chess thinker second only to Steinitz, and his works – Die Blockade, My System and Chess Praxis – established his reputation as one of the father figures of modern chess.

In the 10-year period, it is proposed that insect and disease control on the National Forest System be stepped up to a level of prevention, detection, and control of insect and disease infestations that will substantially reduce the occurrence of large infestations toward the end of the initial period.

It is proposed that in 10 years all commercial timberlands, all critical watersheds, and other lands in the National Forest System developed or proposed for intensive use will be given protection from fire adequate to meet the fire situation in the worst years and under serious peak loads.

* Colonization of Ceres, has been proposed as one possible target for human colonization in the inner Solar System

An earlier, slightly different sense of the term was proposed by John Stuart Mill in his 1843 < cite > System of Logic </ cite >.

Moller International continues to develop the Skycar M400, which is powered by four pairs of in-tandem Wankel rotary engines, and is approaching the problems of satellite-navigation, incorporated in the proposed Small Aircraft Transportation System.

Dyson also has proposed the use of bioengineered space colonies to colonize the Kuiper Belt on the outer edge of our Solar System.

In 1960, the Air Force proposed a radio-navigation system called MOSAIC ( MObile System for Accurate ICBM Control ) that was essentially a 3-D LORAN.

In the Report of the Committee dated 3 September 1947 to the UN General Assembly, the majority of the Committee in Chapter VI proposed a plan to replace the British Mandate with " an independent Arab State, an independent Jewish State, and the City of Jerusalem " ..., the last to be under " an International Trusteeship System ".

They also first proposed a system of standards, the Giorgi System, which ultimately became the SI, or Système International d ’ unités ( in English, the International System of Units ).

Another European project, called WIDENS ( Wireless Deployable Network System ) proposed a bandwidth reservation approach for mobile wireless multirate adhoc networks.

Mass drivers have been proposed for space disposal of nuclear waste, where a projectile launched at much above Earth's escape velocity would escape the Solar System, with atmospheric passage at such speed calculated as survivable through an elongated projectile and very substantial heatshield.

In the end, proposals for these two requirements, called respectively, the Distributed Computing Environment ( DCE ), and the Distributed File System ( DFS ) won over Sun's proposed ONC and NFS.

Examples of satellite constellations include the Global Positioning System ( GPS ), Galileo and GLONASS constellations for navigation and geodesy, the Iridium and Globalstar satellite telephony services, the Disaster Monitoring Constellation and RapidEye for remote sensing, the Orbcomm messaging service, Russian elliptic orbit Molniya and Tundra constellations, the large-scale Teledesic and Skybridge broadband constellation proposals of the 1990s, and the proposed LEO global backhaul constellation named COMMStellation ™.

The American Point System was proposed by taylor porter of Marder Luse & Company in Chicago in the 1870s, and his point system used the same method of size division as Fournier ’ s ; viz.

proposed an interpretation of the volatile enrichment, observed in the four giant planets of the Solar System, with respect to the Solar abundances.

Ten centuries after Bede, the French astronomers Philippe de la Hire ( in the year 1702 ) and Jacques Cassini ( in the year 1740 ), purely to simplify certain calculations, put the Julian Dating System ( proposed in the year 1583 by Joseph Scaliger ) and with it an astronomical era into use, which contains a leap year zero, which precedes the year 1 ( AD ) but does not exactly coincide with the year 1 BC.

The Avrocar was proposed to the U. S. Army as a type of " flying Jeep " that could also serve as a proof-of-concept test vehicle for a later supersonic flying saucer designs, PV-704 and Weapon System 606A.

Three subspecies have been proposed, but are not recognised in the Integrated Taxonomic Information System ( ITIS ).

Longer range communications have been proposed using infrastructure networks such as WiMAX ( IEEE 802. 16 ), Global System for Mobile Communications ( GSM ), or 3G.

The proposed scheme received considerable discussion and was finally incorporated by the state legislature ( 4 March 1846 ) into " An Act to establish a System of Common Schools.

In the 1955 plan for the Interstate Highway System, an Interstate Highway was planned along the Route 23 corridor between Interstate 80 in Wayne and Interstate 287 in Pompton Plains, also connecting to a proposed Interstate along the Route 3 corridor.
