Mercedes-Benz

Mercedes-Benz (German pronunciation: [mɛɐ̯ˈtseːdəs ˈbɛnts]) is a German automobile manufacturer, a multinational division of the German manufacturer Daimler AG. The brand is known for luxury automobiles, buses, coaches, and trucks. The headquarters of Mercedes-Benz is in Stuttgart, Baden-Württemberg, Germany.

The name first appeared in 1926 under Daimler-Benz, but traces its origins to Daimler-Motoren-Gesellschaft's 1901 Mercedes and to Karl Benz's 1886 Benz Patent-Motorwagen, which is widely regarded as the first gasoline powered automobile. Mercedes-Benz's slogan is "The Best or Nothing". Mercedes-Benz is one of the most recognized automotive brands worldwide.

History

Type 77 pistol

The Type 77 (Chinese: 77式手枪; pinyin: 77 shì shǒu qiāng; literally: "Type 77 handgun") is a 7.62×17 mm Type 64 caliber semi-automatic pistol in service with all branches of the People's Liberation Army (PLA) of the People's Republic of China, People's Armed Police and various Chinese police forces. The Type 77 has been the main sidearm of the PLA for over two decades and is slowly being phased out by the QSZ-92 pistol in both military and police service but is still in widespread use across the country amongst second line military units and provincial police forces. Beginning in 1990, several variants of the Type 77 were developed for the international market.

History

Following the successful development of the Type 64 pistol and the silenced Type 64 and Type 67 pistols, the Jinan Military Region Ordnance Factory began development of a self-defense weapon for officers, armed police and public security police in 1976 and by 1978 a design for the new side arm had been selected. In 1981 the design had been finalized for production and was designated as the Type 77.

Day and Night (cellular automaton)

Day and Night is a cellular automaton rule in the same family as Game of Life. It is defined by rule notation B3678/S34678, meaning that a dead cell becomes live (is born) if it has 3, 6, 7, or 8 live neighbors, and a live cell remains alive (survives) if it has 3, 4, 6, 7, or 8 live neighbors, out of the eight neighbors in the Moore neighborhood. It was invented and named by Nathan Thompson in 1997, and investigated extensively by David I. Bell. The rule is given the name "Day & Night" because its on and off states are symmetric: if all the cells in the Universe are inverted, the future states are the inversions of the future states of the original pattern. A pattern in which the entire universe consists of off cells except for finitely many on cells can equivalently be represented by a pattern in which the whole universe is covered in on cells except for finitely many off cells in congruent locations.

Although the detailed evolution of this cellular automaton is very different from Conway's Game of Life, it exhibits complex behavior similar to that rule: there are many known small oscillators and spaceships, and guns formed by combining oscillators in such a way that they periodically emit spaceships of various types.

Highlife (cellular automaton)

Highlife is a cellular automaton similar to Conway's Game of Life. It was devised in 1994 by Nathan Thompson. It is a two-dimensional, two-state cellular automaton in the "Life family" and is described by the rule B36/S23; that is, a cell is born if it has 3 or 6 neighbors and survives if it has 2 or 3 neighbors. Because the rules of HighLife and Conway's Life (rule B3/S23) are similar, many simple patterns in Conway's Life function identically in HighLife. More complicated engineered patterns for one rule, though, typically do not work in the other rule.

Replicator

The main reason for interest in HighLife comes from the existence of a pattern called the replicator. After running the replicator for twelve generations, the result is two replicators. The replicators will repeatedly reproduce themselves, all on a diagonal line. Whenever two replicators try to expand into each other, the pattern in the middle simply vanishes. The behavior of a row of Replicators interacting with each other in this way simulates the one-dimensional Rule 90 cellular automaton, where a single replicator simulates a nonzero cell of the Rule 90 automaton and a blank space where a replicator could be simulates a zero cell of Rule 90. Replicators can be used to engineer other more complex patterns, such as glider guns and high period oscillators.
