VLF tests at IEEE 400.2 test levels do not damage cable systems' 'good' insulation but are used to degrade existing insulation defects to failure during the test rather than in-service. The reasoning is that the low-energy failure of the cable under test results in less collateral damage and a reduced likelihood of unplanned outages due to in ...
The Dunst Opening is a chess opening in which White opens with the move: . 1. Nc3. This fairly uncommon opening may have more names than any other: it is also called the Heinrichsen Opening, Baltic Opening, Van Geet Opening, Sleipnir Opening, Kotrč's Opening, Meštrović Opening, Romanian Opening, Queen's Knight Attack, Queen's Knight Opening, Millard's Opening, Knight on the Left, and (in ...
Much of the site is devoted to the enormous overhead wire antenna array that is necessary to efficiently radiate the VLF waves. The antenna, shown above, consists of ten catenary cables, 5,640–8,700 ft (1,719–2,652 m, 1.1–1.6 miles) long, suspended in a zigzag pattern over the valley between Wheeler mountain and Blue mountain on twelve 200 ft. towers on the mountains' crests.
For example, after 1.c4 Nf6 2.Nc3 g6 3.d4 d5 the game has transposed into the Grünfeld Defence, usually reached by the move order 1.d4 Nf6 2.c4 g6 3.Nc3 d5. White can, however, also play 1.c4 Nf6 2.Nc3 g6 3.e4, making it impossible for Black to reach a Grünfeld, instead more or less forcing them into lines of the King's Indian Defence with 3 ...
The Vienna Game is an opening in chess that begins with the moves: . 1. e4 e5 2. Nc3. White's second move is less common than 2.Nf3, and is also more recent. The original idea behind the Vienna Game was to play a delayed King's Gambit with f4 (the Vienna Gambit), but in modern play White often plays more quietly (for example, by fianchettoing their king's bishop with g3 and Bg2).
VLF transmitter DHO38. The VLF transmitter DHO38 is a VLF transmitter used by the German Navy near Rhauderfehn, Saterland, Germany. It is used to transmit coded orders to submarines of the German Navy and navies of other NATO countries. DHO38 has transmitted since 1982 on 23.4 kHz with a power of up to 800 kilowatts.
White has several different attacking schemes available, but the one considered most dangerous is the Keres Attack, [2] named after GM Paul Keres, which continues 6.g4.This move takes advantage of the fact that 5...e6 cuts off the black’s light squared bishop's control of g4, and plans to force the knight on f6, Black's only developed piece, to retreat.
After 4.Bc4 e6 5.Nc3 a6 6.Ngxe4 Nxe4 7.Nxe4 b5 8.Be2 Bb7 9.Bf3 White had the advantage in Ermenkov–Bonchev, Bulgaria 1970. 3...e5! 4.Nxe4 f5! favors Black. [11] 3...Bf5 and Black has the better position. A continuation might be 4.Nc3 Nf6 and Black keeps the advantage in a solid position.
