omniomni/omni-engineering huggingface dataset:
List of chess software. Chess software comes in different forms. A chess playing program provides a graphical chessboard on which one can play a chess game against a computer. Such programs are available for personal computers, video game consoles, smartphones/tablet computers or mainframes/supercomputers. A chess engine generates moves, but is accessed via a command-line interface with no graphics. A dedicated chess computer has been purpose built solely to play chess. A graphical user interface (GUI) allows one to import and load an engine, and play against it. A chess database allows one to import, edit, and analyze a large archive of past games.

Avery station. The Avery Depot in Avery, Idaho was built by the Chicago, Milwaukee and Puget Sound Railway (also known as The Milwaukee Road) in 1909 as part of its Pacific Extension into the Pacific Northwest from Chicago, Illinois. Avery was the west end of overhead catenary,  which allowed electric locomotives to operate instead of steam engines.

The depot is a rectangular single story wood-frame building built in the Craftsman style. At one end is the passenger waiting area with a freight room at the other end. The station agent's office and lunch room ("beanery") are located between the two.

When the railroad went bankrupt in the 1980s, the depot was sold to the town of Avery for use as a community center. Today it serves as a community center, museum, post office and library. 

The depot was added to the National Register of Historic Places due to its association with the Great Fire of 1910 as an evacuation site.

Green Bay station (Milwaukee Road). The Milwaukee Road Passenger Depot in Green Bay, Wisconsin, was built in 1898 by the Chicago, Milwaukee, St. Paul and Pacific Railroad (also known as The Milwaukee Road) to serve the businesses and residences in Green Bay on the east bank of the Fox River. Two other depots from competing railroads were built on the west bank, including the Green Bay station (Chicago and North Western Railway).

History
The depot is a waypoint on the Packers Heritage Trail. It was built primarily of brick and stone in the Flemish Renaissance Revival style by Charles Sumner Frost of Chicago, Illinois. The architecture is unusual in that most depots of that time were built in the Craftsman or Romanesque styles. The depot is a rectangular, single story building with a passenger waiting area on one end and a freight room at the other.

The depot served Green Bay until 1957, when it was donated by the railroad to the city of Green Bay. (The Milwaukee Road built another passenger depot nearer its rail yards to serve passengers.) The city then leased the old depot to the Chamber of Commerce, then sold it outright in 1986. It is listed in the National Register of Historic Places because of its association with railroad and commercial development of Green Bay and also because of its distinctive architecture.

In 2011, Green-based company Breakthrough Fuel renovated the station to serve as its corporate headquarters. The company received the Green Bay Beautification Award for the renovation later that year.

The Greater Green Bay Community Foundation acquired and improved the station following Breakthrough Fuel's move to Green Bay's Titletown District. The foundation reopened the station to the public on June 21, 2022, where it now serves as a resource for nonprofit organizations, donors and community leaders to find resources the strengthen community.

Alexandra Bridge (Trans-Canada). The Alexandra Bridge is a steel arch bridge across the Fraser River in the lower Fraser Canyon area of southwestern British Columbia, Canada. The two-lane crossing, carrying BC Highway 1, is by road about  north of Hope and  south of Lytton.

Former ferries and bridges
Several ferries and the first and second Alexandra Bridges have existed in the vicinity.

Bridge construction and opening
In 1958, General Construction Co was awarded the bridge substructure ($589,167), but unexpected ground conditions temporarily halted the work, while minor changes were made in the foundations design. The next year, A.I.M. Steel was awarded the steel superstructure ($2,262,283).

In May 1962, the steelwork was complete. At the time, the second longest bridge of this type in the world, the bridge remains the longest one in the Fraser Canyon. For the final phase, Narod Construction was awarded the deck and fence contract ($109,684).

The  length comprises a  arch span and steel girder approach spans with concrete decks. Northeast to southwest, the bridge crosses the Canadian National Railway (CN), Fraser River, and Canadian Pacific Railway (CP).

In October 1962, Highways Minister Phil Gaglardi officially opened the $4 million high level bridge. The increased gross load allowance to  and trailer lengths to  for the highway permitted heavy trucks to use this more direct route rather than the circuitous Hope–Princeton.

Bridge operation
In May 1963, Phil Gaglardi returned for the unveiling of four aluminum fish sculptures, two at each end of the bridge. Standing at the southwest end, a cairn commemorates the contribution of the Royal Engineers in building the Cariboo Road.

The completion of phase 2 of the Coquihalla Highway project (Merritt–Kamloops) in September 1987 created a faster route to the interior, greatly reducing the Fraser Canyon and Alexandra Bridge traffic.

A 2009 report determined the bridge needed major deck rehabilitation and a seismic retrofit. During 2015–2018, Surespan Construction carried out the $22.2 million project. The concrete deck was rehabilitated and extended to , providing wider shoulders with railings upgraded to current standards. Link slabs were installed. Expansion joints and bearings were replaced. Partial painting and sundry repairs were completed. The discovery of some cases of extensive corrosion prompted a second phase of the project, which was undertaken in 2019.

Waggonfabrik Rastatt. () is a German public-limited company based in Rastatt in the state of Baden-Württemberg in southwestern Germany. Its chief products are tramway vehicles and railway coaches and wagons. The firm was founded in  and built, for example, tramways for the Upper Rhine Railway Company (Oberrheinische Eisenbahn-Gesellschaft or OEG), Karlsruhe Transport Company (Verkehrsbetriebe Karlsruhe GmbH) and Stuttgart Tramways (Stuttgarter Straßenbahnen AG). In its early days it also built rolling stock for the Grand Duchy of Baden State Railways.

After the acquisition of the majority of shares by Bauknecht the coach factory in 1971 was converted into a limited liability company (GmbH) and its production was refocussed on the repair and conversion of wagons. After several name changes and takeovers, especially due to the bankruptcy of Bauknecht, it finally became the 'BWR Wagon Repair Company' ().

Different research groups have employed MRPT to implement projects reported in some of the major robotics journals and conferences.

MRPT is free and open-source software released under the BSD 3-clause license; pre-1.0.0 versions were released under the GNU General Public License (GPL).

Some features included in the project as user-applications:
 Visualization and manipulation of large datasets.
 SLAM algorithms: incremental mapping with ICP, Extended Kalman filtering, Rao-Blackwellized particle filters and GraphSLAM.
 Grabbing datasets from robotic sensors.

Upon a selection of the individual libraries provided by MRPT, users can develop new applications.

MRPT participated in Google Summer of Code in 2016–2018.

Representation of metric maps 
Through polymorphism in the design of metric-map classes, observations (such as a laser scans) can be inserted into a grid-map or a map of points, or both simultaneously, transparently to the user.

The following representations of metric maps are implemented:
 Occupancy grid maps
 Point maps
 Landmark maps: discrete elements are 3D points sensed through range and bearing; for example, visual landmarks
 Beacon maps: elements are also 3D points, but sensed by means of range-only devices
 Coloured point maps
 Gas concentration maps
 A multi map, collections of any of the other maps, behaving as one map

Sun position (air combat). The Sun position in aerial combat is the pilot's ability to position the aircraft relative to the Sun in relationship to the position of the enemy aircraft.

The sun position has had different application to different generations of aircraft. During the period when the dogfight dominated air combat, it was used to make visibility and acquisition of own aircraft difficult for the enemy if the Sun was behind own aircraft. With the introduction of infrared homing air-to-air missiles, the use of the Sun by the pilot was used to confuse the missile guidance system.

The advantages of the Sun position were realised early in the history of aerial warfare and is included in the first rule of the Dicta Boelcke.

Rapid transit in Greece. Rapid transit in Greece refers to the systems of rapid transit at present active in Greece.

A "rapid transit", "underground", "subway", "elevated railway", "metro" or "metropolitan railway" system is an electric passenger railway in an urban area with a high capacity and frequency, and grade separation from other traffic. Rapid transit systems are typically located either in tunnels or on elevated rails above street level. Outside urban centers, rapid transit lines may run on grade separated ground level tracks.

In Greece there are several systems that are called "Rapid Transit":
 Athens Metro, an underground and overground railway network serving the city of Athens since 1904;
 Athens Tram, a tram network serving the city of Athens, began electrified service in 1908 and revived in 2001;
 Thessaloniki Metro, an under-underground railway network for Greece's second-largest city;

1971 Harco work-in. The 1971 Harco work-in was an action undertaken by workers at a steel plant in Campbelltown, New South Wales, Australia. The work-in was the culmination of a protracted industrial dispute between the owners of Harco Steel and the workers at the Campbelltown site. The dispute arose as a result of worker objections to the owners' practice of sacking and then rehiring workers to reduce costs during periods of low production.

After a round of sackings in November 1971, the workers decided that strike action, which was common at the site, was no longer an effective tactic for confronting management. Drawing inspiration from the factory occupations in France in 1968 as well as actions taken by the Upper Clyde Shipbuilders in Scotland earlier in 1971, the Harco workers adopted the tactic of the work-in.

The work-in lasted for a period of four weeks. Workers' self-management was practiced, leading to the introduction of the thirty-five hour working week, and an increase in productivity of around 26%.

The owners of Harco responded in a number of ways, including sabotage and legal action. Workers received community support in the form of donations of food and money.

The work-in ended when Harco obtained an order from the Supreme Court of New South Wales, which compelled the workers to leave the site.

Shipboard helicopter operations. Shipboard helicopter operations is the use of techniques which allows operation of rotary wing aircraft from naval vessels. In the case of military vessels the operations also include tactics and associated weapons and troops.

Landing a helicopter on the flight deck of what is sometimes a small ship in heavy seas presents the pilot with a challenges that include: deck movement, turbulent airflows, and using control systems that were not necessarily designed for the marine environment.

Flight operations of shipboard helicopter operations include preparing the aircraft and crew for the mission, cargo and ordnance handling (for armed helicopters), passenger supervision, aircraft departure, communications with the ship during the mission and recovery.

Apart from the more routine passenger and cargo transportation missions, shipboard helicopter operations are used by civilian and military operators to conduct search and rescue missions, while what for the civilian operators is often electronic news gathering, for the military becomes intelligence gathering missions or battlefield surveillance and reconnaissance. Some helicopters, such as the Kamov Ka-31 airborne early warning helicopter, fulfil specialised roles. The SH-60 Seahawk's roles can include antisubmarine warfare, anti-surface warfare, special forces insertion, combat search and rescue, vertical replenishment and medical evacuation.

The first shipboard helicopter operations were attempted by the Wehrmacht during the Second World War in the Baltic Sea. The British had trialled autogyros with aircraft carriers before the war but joined with the USN in testing the Sikorsky helicopters at sea providing the Empire Mersey and its replacement the SS Daghestan in 1942/43. The first purpose-built helicopter operation vessels were Liberty ships converted by the US Army in June 1945 into floating repair depots. They included special landing platforms to accommodate Sikorsky R-4 helicopters.
