Old Indian Defence
The Old Indian Defense is a chess opening defined by the moves: :1. d4 Nf6 :2. c4 d6 This opening is distinguished from the King's Indian Defense in that Black develops their on e7 rather than by fianchetto on g7. Mikhail Chigorin pioneered this defense late in his career. The Old Indian is considered sound, though developing the bishop at e7 is less than the fianchetto, and it has never attained the popularity of the King's Indian. Some King's Indian players will use the Old Indian to avoid certain anti-King's Indian systems, such as the Sämisch and Averbakh Variations. The opening is classified in the ''Encyclopaedia of Chess Openings'' with the codes A53–A55. Main line: 3.Nc3 e5 The Main line is 3. Nc3 e5 4. Nf3 Nbd7 5. e4; White can also play 4.dxe5 dxe5 5.Qxd8+, but despite the displacement of Black's king, this has long been known to offer no advantage, e.g. 5...Kxd8 6.Nf3 Nfd7, with Black often following up with some combination of ...c6, ...Kd8–c7, .. ...

It crosses the border into the county of Staffordshire, and after leaving the Peak District travels through the town of Leek, Staffordshire, Leek. It meets the A523 road (to Macclesfield) and the A520 road (to Stone, Staffordshire, Stone). It crosses the Caldon Canal and travels through the Stoke-on-Trent conurbation, including Hanley, Staffordshire, Hanley and Newcastle-under-Lyme, where it meets a number of major routes such as the A50 road (to Derby), the A500 road, A500 "D-Road," the Winchester-Salford A34 road, A34 and the A525 road (to Whitchurch, Shropshire, Whitchurch).

A53 Steel
ASTM A53 is a carbon steel alloy, used as structural steel or for low-pressure plumbing. The alloy specifications are set by ASTM International, in specification ASTM A53/A53M. A53 pipe comes in three types and two grades, A53 Type F, which is longitudinally furnace butt welded or continuous welded (Grade A only), A53 Type E, which is longitudinally electric resistance welded (Grades A and B), and A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel (Grades A and B). ASTM A53 pipe is sized according to the nominal pipe size (NPS) system. It is commonly available with national pipe thread ends or with plain cut ends. It can be used for steam, water, and air conveyance. It is also weldable and can be used in structural applications, although ASTM A500 tube, which is available in the same NPS sizes, is sometime preferred. This is a standard set by the standards organization ASTM International ASTM International, form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARM Cortex-A53
The ARM Cortex-A53 is one of the first two central processing units implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Cambridge design centre. The Cortex-A53 is a 2-wide decode superscalar processor, capable of dual-issuing some instructions. It was announced October 30, 2012 and is marketed by ARM as either a stand-alone, more energy-efficient alternative to the more powerful Cortex-A57 microarchitecture, or to be used alongside a more powerful microarchitecture in a big.LITTLE configuration. It is available as an IP core to licensees, like other ARM intellectual property and processor designs. Overview * 8-stage pipelined processor with 2-way superscalar, in-order execution pipeline * DSP and NEON SIMD extensions are mandatory per core * VFPv4 Floating Point Unit onboard (per core) * Hardware virtualization support * TrustZone security extensions * 64-byte cache lines * 10-entry L1 TLB, and 512-entry L2 TLB * 4KiB conditional branch predictor, 25 ...
