Pouncing. Pouncing (Italian ) is an art technique used for transferring an image from one surface to another using a fine powder called pounce. It is similar to tracing, and is useful for creating copies of a sketch outline to produce finished works.

Art 
Pouncing has been a common technique for centuries, used to create copies of portraits and other works that would be finished as oil paintings, engravings, and so on. The most common method involves laying semi-transparent paper over the original image, then tracing along the lines of the image by creating pricked marks on the top sheet of paper.  This pounced drawing made of pricked holes is laid over a new working surface. A powder such as chalk, graphite or pastel is forced through the holes to leave an outline on the working surface below, thus transferring the image. The powder is applied by being placed into a small bag of thin fabric such as cheesecloth, then dabbed onto the pricked holes of the pounced drawing.

Lobet Ganagobie. The Ganagobie () is a single place, parasol wing homebuilt aircraft that was built by Willam and James Lobet, first flying in 1953.

Design and development
The first example was built in Lille, France using a 1930 Clerget engine, but was abandoned due to replacement engine availability after the first 23 hours of flight. In 1955 an enlarged version was designed by Gorges Jacquemin, increasing the wing area from . Power was from a Poinsard engine. It was marketed as a plans-built homebuilt aircraft by Falconar Avia.

The aircraft is a single place, strut-braced parasol winged design, with conventional landing gear. The all-wood fuselage with plywood covering has a diamond shaped cross-section. The dual wooden spar wings have aircraft fabric covering. A fuel tank is mounted in each wing root. The design can accommodate engines with as low an output as .

CP Class 1930. The Série 1930 are a class of diesel-electric locomotives formerly used by Portuguese Railways (CP). They are visually very similar to the Série 1900 locomotives, but have a higher top speed of 120 km/h. They were assembled in Portugal by Sorefame, under licence from the French company Alstom and entered service in 1981. The final locomotive in service was withdrawn following failure in October 2018.

They are mainly used on passenger train services. When first introduced, they displaced the Série 1800 locomotives from express passenger trains between Barreiro and the Algarve, but their duties have been reduced since the electrification of the main line between Lisbon and Faro, and now also to Évora.

Hegy Propellers. Hegy Propellers, founded by Ray Hegy, was an American manufacturer of wooden propellers for homebuilt and ultralight aircraft. The company headquarters was located in Marfa, Texas.

Hegy built fixed-pitch two and four bladed propellers with diameters from  for Continental engines, Volkswagen air-cooled engines and Chevrolet Corvair engines. Propellers were made from birch and maple.

History 
Ray Hegy worked in Milwaukee, building propellers for iceboats. This experience qualified him to respond to an ad "for cabinetmakers to build wooden craft propellers" in 1925. Ray Hegy bought his first plane, a Waco-10, in 1928. In 1957, Hegy started building the Chuparosa and was finished after nine years at a cost of $600. The success of the Chuparosa changed Hegy "from a furniture maker and refinisher to a full-time carver of wooden propellers." At that time, Hegy made his propellers in his backyard workshop.

John Carruthers (engineer). John Carruthers (21 June 1836–2 September 1914) was a British engineer and economic theorist from a Scottish literary family. He was born in Inverness, Inverness-shire, Scotland on 21 June 1836.

He worked on railway construction in Canada, America, Russia, Mauritius and Egypt before being recruited by the Premier of New Zealand Julius Vogel for his great Public Works policy of the 1870s which emphasized railway construction and immigration. He was made Engineer-in Chief of the new Public Works Department, responsible for railway construction. 

He resigned in 1878 after the new Minister of Works (James Macandrew) effectively demoted him to having charge of the North Island only. 

In the 1880s he was resident in Venezuela, where he was involved in the construction of the Puerto Cabello and Valencia Railway, which connected the country's second city to the coast. This project was financed by a British company. The line opened in 1888, and included a rack and pinion section at Trincheras. Carruthers had experience of the Fell mountain railway system in New Zealand, but chose the Abt system for this line. 

In 1889 he moved to Argentina to work on the Córdoba North Western Railway. Returning to London in the 1890s, he continued to be a consultant on New Zealand projects until his death.

TAPAAL Model Checker. TAPAAL is a tool for modelling, simulation and verification of Timed-Arc Petri nets developed at Department of Computer Science at Aalborg University in Denmark and it is available for Linux, Windows and Mac OS X platforms.

Timed-Arc Petri Net (TAPN) is a time extension of the classical Petri net model (a commonly used graphical model of distributed computations introduced by Carl Adam Petri in his dissertation in 1962). The time extension considered in TAPN allows for explicit treatment of real-time, which is associated with the tokens in the net (each tokens has its own age) and arcs from places to transitions are labelled by time intervals that restrict the age of tokens that can be used in order to fire the respective transition. In TAPAAL tool a further extension of this model with age invariants with transport arcs (which are more expressive than for example previously considered read-arcs) and with inhibitor arcs is implemented.

The TAPAAL tool offers a graphical editor for drawing TAPN models, simulator for experimenting with the designed nets and a verification environment that automatically answers logical queries formulated in a subset of CTL logic (essentially EF, EG, AF, AG formulae without nesting). It also allows the user to check whether a given net is k-bounded for a given number k. TAPAAL is equipped with its own verification engines distributed together with TAPAAL (one for continuous time  and one for discrete time ). Optionally, the user can automatically translate TAPAAL models 
into UPPAAL and rely on the UPPAAL verification engine.

Graphsim Entertainment. Graphsim Entertainment was founded in 1991 as Graphic Simulations Corp. to develop and publish simulation games. Graphsim's first product was Hellcats Over the Pacific for the Macintosh. It was released in 1991 and developed by Parsoft Interactive.

Description
The game's graphics engine was novel in that it rendered flat-shaded polygons over the entire screen area of a color Mac at native resolution. In 1993 Graphsim released the internally developed F/A-18 Hornet for Macintosh. Based on the eponymous McDonnell-Douglas fighter / attack aircraft it was set in a fictitious Persian Gulf theater of war and featured a detailed cockpit display. F/A-18 Hornet was one of the first simulation games to allow multiple players (four players) to fly together and compete over a local-area network (AppleTalk). It would become the first of a series of F/A-18 games. In 1995 F/A-18 Hornet 2.0 was released for Macintosh, which elevated the level of graphics complexity and simulation detail over its predecessor. In early 1997 Graphsim released F/A-18 Hornet 3.0 for both Macintosh and Windows PC, followed by F/A-18 Korea in late 1997. F/A-18 Korea was set in a fictitious future Korea war theater and featured support for 3DFx graphics cards. It garnered a score of 8.7 as reviewed by editors at GameSpot.com.

In addition to internal development of the F/A-18 Hornet series, Graphsim published for Macintosh a few notable game titles including BioWare's Baldur's Gate and Tales of the Sword Coast, Volition's Red Faction and Summoner, as well as Interplay's Descent 3. Graphsim also published Atari's Falcon 4.0: Allied Force for both Windows and Macintosh, as well as Laminar Research's X-Plane 8, X-Plane 9, and X-Plane 10 Regional.

In 2015 Graphsim Entertainment released FA-18 Hornet for iOS, which remains its only title currently in development.

Games developed

Reception
Computer Gaming World in 1994 stated that "Hornet feels great", praising the game's authenticity but wondering if some inauthenticity with the autopilot and instruments would have made it easier to fly for beginners. The magazine concluded that "F/A-18 Hornet provides an eye-opening and eminently flyable simulation".

Mini Rover ROV. The Mini Rover ROV was the world's first small, low cost remotely operated underwater vehicle (ROV) when it was introduced in early 1983. After a demonstration to industry professionals, in the Spring of 1984, it made a significant entry to the remotely operated vehicle market. It is a self-propelled, tethered, free swimming vehicle that was designed and built by Chris Nicholson of Deep Sea Systems International, Inc. (DSSI). The Mini Rover ROV entered the ROV market at a price of $26,850 when the next lowest cost ROV was $100,000. Nicholson built the first Mini Rover ROV in his garage in Falmouth, MA. It was 26 inches long and weighed 55 pounds. It could be carried on airplanes as luggage.

The Mini Rover ROV has been involved in many undersea expeditions including the 1989 3D filming of the SS Edmund Fitzgerald and the 1989 and 1990 Pearl Harbor Project with the National Park Service and National Geographic to survey the USS Arizona Memorial.

In the 1989 James Cameron film, The Abyss, the Mini Rover MKII ROV is credited as "Little Geek".

The size and portability of the Mini Rover ROV made it easily deployable for emergency situations anywhere in the world. On November 2, 1999, a Mini Rover ROV was on board the USNS Mohawk (T-ATF-170) at the scene of the October 31, 1999, EgyptAir Flight 990 crash site to be used to identify target locations.

Benthos, Inc. (Teledyne Benthos) acquired exclusive designs, trademarks, marketing and manufacturing rights for the Mini Rover ROV from DSSI in 1987. Benthos had been manufacturing and servicing the Mini Rover ROV for DSSI since 1984.
