Compagnia Generale di Elettricità. The Compagnia Generale di Elettricità S.p.A. (General Electric Power Company) was an Italian joint-stock company founded in 1921 in Milan. The company was widely known in Italy simply by the acronym CGE, as it was primarily owned and managed by General Electric (widely known as GE), of the United States.

CGE manufactured electrical applications, simple high-voltage transformers, generators, powerplants and engines for trains and trolleybuses, in particular.
It manufactured a certain number of its products for the European market. In the transport sector, CGE was well known for its electrical components that equipped many types of rolling stock, trolley buses, and other railway and locomotive applications. During its active period, CGE competed against two Italian companies: Ansaldo and "Italian Tecnomasio Brown Boveri" (TIBB).

The company was later the EMC Traction Operating Unit of Ansaldo Transmissione e Distribuzione S.r.l. and was acquired by IMPulse NC, INC. in 2000.

Kamov Ka-115. The Kamov Ka-115 Moskvichka is a light multi-purpose helicopter designed for many uses, including passenger and cargo transportation, emergency service, SAR and patrol, or charter flights.

Design and development

Development is based on extensive use of advanced technologies tested to ensure high performance and reduce operating costs. 
A full-scale mockup of the helicopter was first built to optimize the layout of technological, operational, and ergonomic features. A wind tunnel model TsAGI was created to test flight characteristics and improve aerodynamic airframe layout. Laboratories tested the air intakes' dust device to improve efficiency. A model of the Ka-115 was presented at the aerospace show MAKS-95 in Zhukovsky. Prototype's first flight was 1999 and the aircraft is in production.

The basic Ka-115 is powered by a Pratt & Whitney Canada/Klimov PW206K/2 engine that drives a coaxial rotor system, equipped with rotor de-icing. The Ka-115 features a large five-door cabin with large windows and a skid undercarriage. The cabin is fitted with vibration and noise suppression, heating and ventilation systems, and comfortable shock-absorbing crew and passenger seats.

Edward C. Kilbourne. Edward Corliss Kilbourne (1856–1959) was the founder of the Seattle public electricity system.

Kilbourne was born in Vermont in 1856 and was raised in Aurora, Illinois. He lived in Colorado before moving out to Seattle where he had been preceded by his uncle Corliss P. Stone. Kilbourne was trained as a dentist but became active in numerous other fields of endeavor.

Together with his uncle Corliss P. Stone he was the developer of city of Fremont, annexed in 1891 to become a neighborhood of Seattle. He was a pioneer in urban mass transit having founded a horse trolley line.

He was the founder of the first electric railway in Seattle. He and his uncle Corliss Stone were among the founders of the Union Electric Company. After it was acquired by the city Kilbourne became superintendent of the Seattle Lighting Department, a municipal electricity system, later Seattle City Light. He also supported the YMCA after the original backer Dexter Horton had withdrawn his support and was involved with the Plymouth Congregational Church of Seattle.

BQM-145 Peregrine. The Teledyne Ryan BQM-145 Peregrine (manufacturer designation Model 350) is a reconnaissance unmanned aerial vehicle (UAV) developed in the United States in the 1990s as a joint U.S. Navy/Marine Corps and Air Force "Medium Range UAV" program, with the Navy developing the airframe and the Air Force providing the payload. The BQM-145A was designed to precede airstrike packages into a target area and relay reconnaissance information in real time.

Design and development
Production BQM-145As were to have a metal airframe, but the initial two prototypes were built with plastic composites, with initial flight in May 1992. The program then collapsed in 1993 due to technical difficulties and funding cutbacks. Six BQM-145As with plastic-composite airframes then under construction were later completed, with first flight of a composite BQM-145A in 1997.

Operational history
Apparently Northrop Grumman has continued to use the BQM-145As for other experiments. Some sources claim they have been evaluated for unmanned strike missions, and paintings have been circulated showing a BQM-145A fitted with a "high-power microwave (HPM)" generator in the nose to fry adversary electronic equipment. It has been confirmed that BQM-145As have been flown in the US on test flights carrying HPM payloads.

The BQM-145A has some broad similarities to the Scarab, with a similar configuration except that it has twin air intakes on either side of the fuselage, just forward of the wing roots. Like the Scarab, it has no landing gear. It is powered by a Teledyne CAE F408-CA-400 (Model 382-10C) turbofan engine, with  thrust. It can be air launched from a standard fighter aircraft such as the F-16 or the F/A-18.

Aurora Goldeneye. The Aurora Goldeneye is a reconnaissance UAV under development in the United States during the first decade of the 21st century. It is a ducted fan design in roughly the same class as the Sikorsky Cypher II. This UAV was built under a DARPA contract and is apparently focused on covert or special forces operations.

The Goldeneye is a "tail-sitter" or "pogo" machine that takes off and lands straight up. It is a stumpy-looking machine with four tailfins, each with landing gear on the fintip, and a wing that pivots, allowing it to be aligned with the aircraft centerline in cruise flight and at a right angle to the centerline in hover flight.

The Goldeneye is built of graphite and fiberglass composites, and has a low radar, infrared, and acoustic signature. It is powered by a 28 kW (38 hp) Wankel-rotary engine from AV Engines Ltd in the UK. It has an autonomous flight control system with GPS-INS navigation.

The Goldeneye can carry a small electo-optic sensor turret or other payload and features a radio datalink. Apparently the DARPA specification mysteriously required that it be able to carry "two coke-can size payloads" that were not described further. Aurora is working on a half-scale version of the Goldeneye for commercial sales.

Freewing Scorpion. 

The Freewing Scorpion is a reconnaissance UAV of the United States, developed in the early 21st century by Freewing Aerial Robotics Corpation, associated with the University of Maryland, College Park. Working with well-known small-aircraft designer Burt Rutan, Freewing designed a series of piston-powered short-takeoff-and-landing UAVs, based on a design where the fuselage pivots relative to the wing surfaces. The "freewing" design also allows the UAV to operate as a stable observation platform during turbulent conditions.

The Scorpion will be offered for a US Army short-range UAV requirement, and is being proposed by Matra of France for use on French navy frigates and patrol boats. The Matra version is named "Marvel" and will carry a Matra-designed electro-optical day-night camera system initially, but the French navy has expressed interest in extending the payload to include communications relay, electronic warfare, and antisubmarine warfare equipment. Freewing is also offering the similar but smaller "Scorpiette", with a payload of up to 6.8 kilograms (15 pounds) for commercial, third-world militarizes, and law enforcement organizations.

AN/UYK-7. The AN/UYK-7 was the standard 32-bit computer of the United States Navy for surface ship and submarine platforms, starting in 1970. It was used in the Navy's NTDS & Aegis combat systems and U.S. Coast Guard, and the navies of U.S. allies.  It was also used by the U.S. Army.

Technical 
Built by UNIVAC, it used integrated circuits, had 18-bit addressing and could support multiple CPUs and I/O controllers. Three CPUs and two I/O controllers were a common configuration. Its multiprocessor architecture was based upon the UNIVAC 1108.  An airborne version, the UNIVAC 1832, was also produced.

Replacement 
In the mid-1980s, the UYK-7 was replaced by the AN/UYK-43 which shared the same instruction set. Retired systems are being cannibalized for repair parts to support systems still in use by U.S. and non-U.S. forces.

Allen Scythe. The Allen Scythe, sometimes called the Allen Power Scythe, is a petrol-powered finger-bar mower. It was made from 1933 until 1973 by John Allen and Sons in Cowley, Oxfordshire. The company, formerly the Eddison and Nodding Company, was bought in 1897 by John Allen, who renamed it the Oxford Steam Plough Company, and then renamed it to John Allen and Sons.

Description
The Allen Scythe does not resemble a hand scythe but serves the same purpose. The engine drives a  or  or 4ft wide toothed blade sliding back and forth horizontally across stationary teeth to produce a scissor action, and also drives two large wheels for forward travel. There are handles to allow the machine to be controlled by an operator walking behind it, controls comprise throttle and clutch. The wheels are driven through ratchets which allow either wheel to free-wheel when steering the machine (the wheel on the outside of the turn will be able to rotate faster than the inside wheel). This system is simpler than a differential axle and, unlike a differential, means that when one wheel slips the other keeps turning and driving the machine forwards. It has the disadvantage that the machine can run away from the operator downhill and for this reason the ratchet mechanisms can be locked. The machines are extremely robust and many from the 1950s are still in regular use.  They can be dangerous, as the clutch system only disengages the wheel drive from the engine: the blades cut all the time the engine runs.

Later models were available with different attachments, including rotating brushes that replaced the cutting head, air or water pumps and saws or hedge trimmers that drove from the starting pulley side of the engine.

Engine
John Allen and Sons used a number of engine types, the most common being a Villiers two-stroke with magneto ignition and rope start. The engines may fail to start because of ignition problems. The spark should occur when the piston is 3/16 of an inch before top dead centre (TDC) on all Villiers engines except for the Villiers Mk. 11C & 25C which should spark 5/32 of an inch before TDC.

Popular culture
Episode 6 of the BBC Two reality television series Wartime Farm featured an Allen Scythe. Cast members Alex Langlands and Peter Ginn used it to harvest hay in a churchyard.

PCASTL. The PCASTL (an acronym for by Parent and Childset Accessible Syntax Tree Language) is an interpreted high-level programming language.  It was created in 2008 by Philippe Choquette.  The PCASTL is designed to ease the writing of self-modifying code.  The language has reserved words parent and childset to access the nodes of the syntax tree of the currently written code.

Hello world
The "Hello world program" is quite simple:
<nowiki>
"Hello, world!"
</nowiki>
or
<nowiki>
print("Hello, world!")
</nowiki>
will do the same.

Syntax
The syntax of PCASTL is derived from programming languages C and R.  The source of R version 2.5.1 has been studied to write the grammar and the lexer used in the PCASTL interpreter.

Influences
Like in R, statements can, but do not have to, be separated by semicolons.  Like in R, a variable can change type in a session.  Like in C and R, PCASTL uses balanced brackets ({ and }) to make blocks.

Operators found in PCASTL have the same precedence and associativity as their counterparts in C.  for loops are defined like in C. ++ and -- operators are used like in C to increment or decrement a variable before or after it is used in its expression.

An example of PCASTL using the for reserved word and the ++ operator:
for (i = 1; i < 4; i++) print(i)

Functions and comments in PCASTL are defined like in R:
# function definition (comment)
a = function()
{
   print("Hello, world!")
}

# function call
a()

parent and childset reserved words

Those reserved words can only be written lowercase and will not be recognized otherwise.  The parent reserved word gives a reference to the parent node in the syntax tree of the code where the word is placed.  In the following code, the parent node is the operator =.

<nowiki>
a = parent
</nowiki>

The variable "a" will hold a reference to the = node.  The following code shows how to get references to the two child nodes of the operator = with the childset reserved word.
<nowiki>
a.childset[0]
a.childset[1]
</nowiki>

To display the value of "a", some ways are given in this example:
<nowiki>
a
a.childset[0].parent
a.childset[1].parent
a.childset[0].parent.childset[0].parent # and so on...
</nowiki>

In the following code: we assign a code segment to the right child of the = node, we execute the = node a second time and we call the newly defined function.
<nowiki>
a.childset[1] = `function() print("hello")'
execute(a)
a()
</nowiki>

Kristian Hindhede. Kristian Hindhede (surname pronounced as hin-d-her)(19 August 1891 – 8 January 1969) was a Danish civil engineer and industrialist. He was a son of the physician and nutritionist Mikkel Hindhede.

In the 1920s, Kristian Hindhede pioneered the use of ready-mix concrete trucks with a horizontal rotating drum mixer. He is described as the inventor of this vehicle in the Danish Who's Who Kraks Blå Bog. As early as 1916, Stephen Stepanian of Columbus, Ohio, developed a self-discharging motorized transit mixer that was the predecessor of the modern ready-mix concrete truck, but the patent that Stepanian filed in 1916 was rejected in 1919. The poor quality of motor trucks at the time was a problem for inventors.

Hindhede's company A/S De danske Betonfabrikker (later renamed KH Beton) evolved into Unicon A/S, Scandinavia's largest supplier of ready-mix concrete. It was acquired by Aalborg Portland in 1927.

Mirach 26. The Mirach 26 is a reconnaissance UAV developed in Italy during the 1990s, based on the Mirach 20 target drone. The initial work on the design was carried out by Meteor CAE before this company was absorbed by Galileo Avionica, then Selex ES (merged into Leonardo-Finmeccanica since 2016).

The Mirach 26 is of typical twin-boom pusher-prop battlefield surveillance UAV configuration. It is very similar to the older Mirach 20 in appearance but slightly bigger, the most visible difference being that the Mirach 26 has antenna disks on the top of the tailfins. It is powered by a 20 kW (26 hp) Sachs piston engine.

FOSD metamodels. Feature-oriented software development (FOSD) is a general paradigm for software generation, where a model of a product line is a tuple of 0-ary and 1-ary functions (program transformations). This page discusses a more abstract concept of models of product lines of product lines (PL**2) called metamodels, and product lines of product lines of product lines called meta-metamodels (PL**3), and further abstract concepts.

Metamodels 
A metamodel is a model whose instances are models. A GenVoca model of a product line is a tuple whose components are features (0-ary or 1-ary functions).  An extension (a.k.a. delta or refinement) of a model is a "meta-feature", which is a tuple of deltas that can modify an existing product line by modifying existing features and adding new features. As a simple example, consider GenVoca model M that contains three features a-c: 

 

Suppose meta-model MM contains three meta-features AAA-CCC, each of which
is a tuple with a single non-identity feature:

 

where 0 is the null feature. Model M is constructed by adding the meta-features of MM, where + is the composition operation (see FOSD).

MM models a product line of product lines (PL**2). That is, different MM expressions correspond to GenVoca models of different product lines..
