William Hurst (civil engineer). William Hurst (1810-1890) was a Scottish civil engineer noted for his involvement in early railway construction in Britain.

Life

He was born in Markinch in Fife on 5 January 1810. He served an apprenticeship as an engineer in Liverpool Docks from 1824.
In 1845 he became the Railway Superintendent of the Manchester and Bolton Railway based at Salford. In 1846 the company was absorbed into the Manchester and Leeds Railway and then in 1847 became part of the Lancashire and Yorkshire Railway. In 1849 he moved from Salford to Miles Platting. Together with Richard Hodgson and Thomas Rowbotham they brought the new railway company to a high level of success.

In 1867 he became Locomotive Superintendent of the North British Railway. In this role he constructed 22 locomotives in Leith and a further two in Burntisland. Hurst at this time was earning £1200 per annum, more than twice the norm for engineers in the same role. In a scandal of 1867 Hurst and his two partners were forced to resign following the discovery that the company from whom the North British Railway hired their rolling stock (the Scottish Wagon Company) which was owned by the same three men. He returned to work in much lesser roles.

In retirement he lived at 17 Melville Terrace in Marchmont, Edinburgh.

He died in Edinburgh on 22 December 1890 and is buried in Warriston Cemetery in northern Edinburgh. The grave lies against the southern wall of the main cemetery, backing onto the Water of Leith Walkway.

Family
He was married to Ann Calder (1815-1896) in June 1838 in Liverpool. They had one son, William P. Hurst (1846-1866) and two daughters, Annie and Isabella.

South African type ET tender. The South African type ET tender was a steam locomotive tender.

Type ET tenders entered service in 1947 and 1948, as tenders to the last batch of 100 Class 15F  Mountain type steam locomotives which entered service on the South African Railways in those years.

Manufacturer
Type ET tenders were built in 1947 and 1948 by North British Locomotive Company (NBL).

The South African Railways (SAR) placed its last batch of 100 Class 15F locomotives in service in 1947 and 1948. The original Class 15F locomotive and tender had been designed in 1938 by W.A.J. Day, Chief Mechanical Engineer (CME) of the South African Railways (SAR) from 1936 to 1939, while this last version was built to modified designs by Doctor M.M. Loubser, who succeeded Day as CME in 1939. These 100 engines and their tenders were equipped with mechanical stokers.

Characteristics
The tender rode on four-wheeled bogies and was virtually identical to the earlier Type JT tender, but equipped with a mechanical stoker. Like the Type JT, it also had a  coal capacity and a maximum axle load of , but a  smaller water capacity of  to accommodate the mechanical stoker mechanism, while its empty weight was  more due to the additional stoking equipment. These appear to have been the only differences between the Types JT and ET tenders.

Locomotives
Only the last batch of 100 Class 15F locomotives, built by NBL, were delivered new with Type ET tenders, which were numbered in the range from 3057 to 3156 for their engines. An oval number plate, bearing the engine number and often also the locomotive class and tender type, was attached to the rear end of the tenders.

Classification letters
Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR. The first letter of the tender type indicates the classes of engines to which it can be coupled. The "E_" tenders were arranged with mechanical stokers and could be used with the locomotive classes as shown.
 Class 15F, if equipped with a mechanical stoker.
 Class 23.
 Class 25NC.
 Class 26.

The second letter indicates the tender's water capacity. The "_T" tenders had a capacity of between .

A number, when added after the letter code, indicates differences between similar tender types, such as function, wheelbase or coal bunker capacity.

Modifications
A subdivision of the Type ET tender was created when the coal bunkers of some of the tenders were enlarged to a  capacity. Such tenders were reclassified to Type ET1.

Sunway SW26010. The SW26010 is a 260-core manycore processor designed by the Shanghai Integrated Circuit Technology and Industry Promotion Center (ICC for short)(Chinese: 上海集成电路技术与产业促进中心 (简称ICC)). It implements the Sunway architecture, a 64-bit reduced instruction set computing (RISC) architecture designed in China. The SW26010 has four clusters of 64 Compute-Processing Elements (CPEs) which are arranged in an eight-by-eight array. The CPEs support SIMD instructions and are capable of performing eight double-precision floating-point operations per cycle. Each cluster is accompanied by a more conventional general-purpose core called the Management Processing Element (MPE) that provides supervisory functions. Each cluster has its own dedicated DDR3 SDRAM controller and a memory bank with its own address space.
The processor runs at a clock speed of 1.45 GHz. 

The CPE cores feature 64 KB of scratchpad memory for data and 16 KB for instructions, and communicate via a network on a chip, instead of having a traditional cache hierarchy. The MPEs have a more traditional setup, with 32 KB L1 instruction and data caches and a 256 KB L2 cache. Finally, the on-chip network connects to a single system interconnection interface that connects the chip to the outside world.

The SW26010 is used in the Sunway TaihuLight supercomputer, which between March and June 2018, was the world's fastest supercomputer as ranked by the TOP500 project. The system uses 40,960 SW26010s to obtain 93.01 PFLOPS on the LINPACK benchmark.

Successor: SW26010P 
SW26010P includes 6 core groups (CGs), each of which includes one management processing element (MPE), and one 8×8 computing processing element (CPE) cluster. Each CG has its memory controller (MC), connecting to 16 GB of DDR4 memory with a bandwidth of 51.2 GB/s. The data exchange between every two CPEs in the same CPE cluster is achieved through the Remote Memory Access (RMA) interface (a replacement of the register communication feature in the previous generation). Each CPE has a fast local data memory (LDM) of 256 KB. Each SW26010P processor consists of 390 processing elements.

Holographic Lexan Bubble Chamber. The Holographic Lexan Bubble Chamber, HOLEBC, was a hydrogen bubble chamber.

Bubble chambers are similar to cloud chambers, both in application and in basic principle. A chamber is normally made by filling a large cylinder with a liquid heated to just below its boiling point.  As particles enter the chamber, a piston suddenly decreases its pressure, and the liquid enters into a superheated, metastable phase.  Charged particles create an ionization track, around which the liquid vaporizes, forming microscopic bubbles. Bubble density around a track is proportional to a particle's energy loss. Bubbles grow in size as the chamber expands, until they are large enough to be seen or photographed. Several cameras are mounted around it, allowing a three-dimensional image of an event to be captured.

The HOLEBC chamber was built to be used with the huge European Hybrid Spectrometer at CERN to measure the momentum of particles as they emerged from the chamber.
