Amber (processor core)

The Amber processor core is an open-source ARM-compatible 32-bit RISC processor. It is hosted on the OpenCores website and is part of a movement to develop a library of open source hardware intellectual property. The Amber core is fully compatible with the ARMv2 instruction set and is therefore supported by the GNU toolchain. This older version of the ARM instruction set is supported because it is not covered by patents so can be implemented without a license from ARM Holdings, unlike some previous open source projects. The Amber project provides a complete embedded FPGA system incorporating the Amber core and a number of peripherals, including UARTs, timers and an Ethernet MAC.

There are two versions of the core provided in the Amber project. The Amber 23 has a 3-stage pipeline, a unified instruction and data cache, a Wishbone interface, and is capable of 0.75 DMIPS per MHz. The Amber 25 has a 5-stage pipeline, separate data and instruction caches, a Wishbone interface, and is capable of 1.0 DMIPS per MHz. Both cores implement exactly the same ISA and are 100% software compatible.

Amber Josephine Liu (born September 18, 1992), also known as Amber, is a Chinese American rapper and singer currently active in South Korea. She is a member of the South Korean girl group f(x). She debuted as a solo artist in February 2015 with the release of her EP, Beautiful.

Early life

Amber was born on September 18, 1992 in Los Angeles, California. Her parents are from Taiwan and her father has Teochew ancestry. She has one older sister named Jackie. She attended El Camino Real High School in Los Angeles prior to moving to South Korea to be a trainee under S.M. Entertainment.

Career

F(x)

Amber was cast from S.M. Entertainment's Los Angeles global audition in 2008, where she and one male were selected to be trainees for SM Entertainment. After a year and a half of training, she debuted under the new South Korean girl group f(x) in September 2009. During an episode of the group's reality show, Go f(x), Amber revealed that her parents initially had mixed feelings regarding her music career. She stated: "My dad was very cautious, at first ...but then my mom was always supportive from the beginning. I really thank her and she also convinced my dad".

Settle-Carlisle Line

The Settle–Carlisle Line (S&C) is a 73-mile (117 km) long main railway line in northern England. It is also known as the Settle and Carlisle. It is a part of the National Rail network and was constructed in the 1870s. Apart from temporary diversions (such as the closure of the West Coast Main Line) all passenger trains are operated by Northern Rail.

The line runs through remote, scenic regions of the Yorkshire Dales and the North Pennines, from near the town of Settle, beginning at a junction with the line from Leeds to Morecambe, extending to the city of Carlisle close to the England/Scotland border. On the way the line passes through the town of Appleby-in-Westmorland and a number of small communities.

History

The S&C had its origins in railway politics; the expansion-minded Midland Railway company was locked in dispute with the rival London and North Western Railway over access rights to the latter’s tracks to Scotland.

The Midland's access to Scotland was via the "Little North Western" route to Ingleton. The Ingleton Branch Line from Ingleton to Low Gill, where it joined the Lancaster and Carlisle Railway, was under the control of the rival LNWR. Initially the routes, although physically connected at Ingleton, were not logically connected, as the LNWR and Midland could not agree on sharing the use of Ingleton station. Instead the LNWR terminated its trains at a station at the end of Ingleton viaduct, and Midland Railway passengers had to change into LNWR trains by means of a walk of about a mile over steep gradients between the two stations.

Global Combat Ship

The Type 26 Global Combat Ship, or simply Type 26, is a ship design and construction programme of the Ministry of Defence of the United Kingdom, to replace the thirteen Type 23 frigates of the Royal Navy and for export.

The programme started in 1998, named "Future Surface Combatant" (FSC). In March 2010 BAE Systems Maritime – Naval Ships was awarded a four-year contract to develop the Type 26 Global Combat Ship. The design passed Main Gate 1, with Demonstration Phase starting 1 April 2015, manufacturing planned to begin in 2016 and the first Type 26 to be delivered in 2022.

Development

Future Surface Combatant

The Global Combat Ship started development under the original Future Surface Combatant (FSC) programme intended to replace the Royal Navy's Type 22 and Type 23 frigates. Planning for a replacement escort vessel started in 1998 with the ordering of a research vessel, the RV Triton, to study whether a trimaran design was practical for such a large and complex vessel. However, by the early 2000s it was apparently obvious the Royal Navy favoured more conventional designs. In March 2005, plans were released for a two-class solution, a cheaper "Medium Sized Vessel Derivative" entering service in 2016-19 and a more capable "Versatile Surface Combatant" entering service around 2023.

USS SC-21

USS SC-21, until July 1920 known as USS Submarine Chaser No. 21 or USS S.C. 21, was an SC-1-class submarine chaser built for the United States Navy during World War I.

SC-21 was a wooden-hulled 110-foot (34 m) submarine chaser built at the New York Navy Yard at Brooklyn, New York. She was commissioned on either 20 September or 19 October 1917 as USS Submarine Chaser No. 21, abbreviated at the time as USS S.C. 21, under the command of Lieutenant Alfred Y. Lanphier, who later would become the commander of the USS Patterson Group of submarine chasers.

Assigned to the Second Naval District, S.C. 21 operated with the Experimental Unit at New London, Connecticut. On 6 May 1918, Lieutenant, junior grade, Henry Hartley was relieved of command of Submarine Chaser No. 253 and took command of S.C. 21.

When the U.S. Navy adopted its modern hull number system on 17 July 1920, Submarine Chaser No. 21 was classified as SC-21 and her name was shortened to USS SC-21.

On 24 June 1921, the Navy sold SC-21 to Joseph G. Hitner of Philadelphia, Pennsylvania.

Charles Messier

Charles Messier (French: [me.sje]; 26 June 1730 – 12 April 1817) was a French astronomer most notable for publishing an astronomical catalogue consisting of nebulae and star clusters that came to be known as the 110 "Messier objects". The purpose of the catalogue was to help astronomical observers, in particular comet hunters such as himself, distinguish between permanent and transient visually diffuse objects in the sky.

Biography

Messier was born in Badonviller in the Lorraine region of France, being the tenth of twelve children of Françoise B. Grandblaise and Nicolas Messier, a Court usher. Six of his brothers and sisters died while young and in 1741, his father died. Charles' interest in astronomy was stimulated by the appearance of the spectacular, great six-tailed comet in 1744 and by an annular solar eclipse visible from his hometown on 25 July 1748.

In 1751 he entered the employ of Joseph Nicolas Delisle, the astronomer of the French Navy, who instructed him to keep careful records of his observations. Messier's first documented observation was that of the Mercury transit of 6 May 1753.
