Launch of Progress freighter to Mir scrubbed". Spaceflight Now. 18 January 2001. Archived from the original on 7 June 2011 . Retrieved 7 June 2009. The fourth phase of the M1 is still ongoing and involves upgrading and improving the existing motorway sections to meet the current and future traffic needs. M1 Pro and M1 Max introduce a system-on-a-chip (SoC) architecture to pro systems for the first time. The chips feature fast unified memory, industry-leading performance per watt, and incredible power efficiency, along with increased memory bandwidth and capacity. M1 Pro offers up to 200GB/s of memory bandwidth with support for up to 32GB of unified memory. M1 Max delivers up to 400GB/s of memory bandwidth — 2x that of M1 Pro and nearly 6x that of M1 — and support for up to 64GB of unified memory. And while the latest PC laptops top out at 16GB of graphics memory, having this huge amount of memory enables graphics-intensive workflows previously unimaginable on a notebook. The efficient architecture of M1 Pro and M1 Max means they deliver the same level of performance whether MacBook Pro is plugged in or using the battery. M1 Pro and M1 Max also feature enhanced media engines with dedicated ProRes accelerators specifically for pro video processing. M1 Pro and M1 Max are by far the most powerful chips Apple has ever built.

Below are some common spanner (wrench) sizes for metric screw threads. Hexagonal (generally abbreviated to "hex") head widths (width across flats, spanner size) are for DIN 934 hex nuts and hex head bolts. Other (usually smaller) sizes may occur to reduce weight or cost, including the small series flange bolts defined in ISO 4162 which typically have hexagonal head sizes corresponding to the smaller 1st choice thread size (eg. M6 small series flange bolts have 8mm hexagonal heads, as would normally be found on M5 bolts). [9] The final section of the M1 was opened to junction 1 at Staples Corner in 1977. There the motorway meets the North Circular Road (A406) at a grade separated junction and roundabout. Unrealised plans from the 1960s would have seen the motorway continue through the junction on an elevated roadway to end at West Hampstead, where it would have met the North Cross Route, the northern section of the London Motorway Box, a proposed ring of urban motorway around the central area. The layout of the Staples Corner junction was originally built in accordance with those plans, although most of the London Ringways Plan had been cancelled by 1973. Around the same time, the section between the then-M10 and junction 5 was widened from the original two lanes to three. The third phase of the M1 also faced some challenges from weather conditions and roadworks that affected the construction and operation of the motorway. Some delays and disruptions were caused by snow, ice, rain and fog. Some repairs and maintenance were also needed to fix the damage caused by wear and tear, accidents and vandalism. The Fourth Phase: 1999-present

Junction improvements are works that modify or rebuild the existing junctions to improve their capacity, safety and efficiency. They can involve adding or removing lanes, changing layouts, installing signals or roundabouts, or creating new access roads or bridges.

On 8 January 1989, a Boeing 737 crashed onto the embankment of the M1 whilst attempting an emergency landing at East Midlands Airport in Leicestershire. [ citation needed] There were no ground casualties nor vehicular damage on the motorway as a result of the crash, however 47 passengers on board the aircraft were killed and a further 74 passengers and crew members were seriously injured.

The M1 contains dedicated neural network hardware in a 16-core Neural Engine, capable of executing 11 trillion operations per second. [11] Other components include an image signal processor, a PCIe storage controller, a USB4 controller that includes Thunderbolt 3 support, and a Secure Enclave. The M1 Pro, Max and Ultra support Thunderbolt 4. Originally, the M1 was planned to end at Doncaster but it was decided to make what was going to be the " Leeds and Sheffield Spur" into the primary route, with the 11-mile (18km) section to the A1(M) south of Doncaster given the separate motorway number M18. The table below shows the various SoCs based on the "Firestorm" and "Icestorm" microarchitectures. [46] [47] Variant

The M1 Ultra doubles the specs of the M1 Max for a 1024-bit or 1-kilobit memory bus with 800GB/s bandwidth in a 64GB or 128GB configuration. These major UK towns and cities can easily be reached from the motorway; London, Brent Cross, Watford, St Albans, Hemel Hempstead, Luton, Milton Keynes, Northampton, Rugby, Leicester, Loughborough, Nottingham, Derby, Mansfield, Chesterfield, Sheffield, Rotherham, Barnsley, Wakefield and Leeds.

Retrieved 2020-11-14.The M1 motorway connects London to Leeds, where it joins the A1(M) near Aberford, to connect to Newcastle. It was the first inter-urban motorway to be completed in the UK; [2] the first motorway in the country was the Preston Bypass, which later became part of the M6. [3] The M1 motorway connects London to Leeds, and stretches 193.6 miles in length. It opened in 1959 as the UK’s first motorway - it actually featured the very first motorway services, Watford Gap - and was built in four phases. When the M1 first opened, it was a very different motorway to today; in its early days there were no speed limits in place for vehicles and no crash barriers or central reservation. Resurfacing is work that replaces or repairs the existing surface of the motorway to improve its quality and durability. It can involve removing or laying new asphalt, concrete or gravel or applying new markings or coatings.
