Business model pattern. Business model patterns are reusable business model architectural components, which can be used in generating a new business model. In the process of new business model generation, the business model innovator can use one or more of these patterns to creating a new business model. Each of these patterns has similarities in characteristics, business model building blocks arrangements and behaviors. Alexander Osterwalder call these similarities the "business model pattern".

"Innovation, entrepreneurship and disruption are not about creative genius",
says A. Osterwalder explaining the need for business model patterns.

Given the goal of reducing costs of the complex software development, it is necessary to use ready-made unified solutions. The pattern facilitates communication between developers via referring to well-known constructions and reduces the number of errors.

George James Snelus. George James Snelus  (25 June 1837 - 1906) was an English metallurgist, known to be the first to remove phosphorus from pig iron, by oxidizing it in a converter lined with basic refractory materials. Facing difficulties to perform a reliable and cheap lining, he delayed further improvements and failed to find a practical solution, which was finally found by Sidney Gilchrist Thomas.

Snelus was born in Camden Town, London and educated at St John's College, Battersea. He attended lectures at Owen's College, Manchester and in 1864 was awarded a scholarship to the Royal School of Mines. He was recommended by his lecturer there to William Menelaus at the Dowlais Iron Works as a suitable candidate for the position of works chemist, a position he held for 5 years. 

In 1871 he was commissioned by the Iron and Steel Institute to visit America and investigate a new process, the Danks system of puddling. Whilst researching the process he discovered that phosphorus could be removed from molten iron by using lime as a furnace liner, a discovery he patented. The process was later developed for practical use by Sidney Gilchrist Thomas and Percy C. Gilchrist. 

Snelus was awarded the 1883 Bessemer Gold Medal of the Iron and Steel Institute jointly with Thomas for their work on dephosphorization and Snelus also shared the financial benefits of the basic process patents with both the other researchers. He was elected a Fellow of the Royal Society in 1887   and was awarded gold medals at both the Inventions Exhibition in 1885 and the Paris Exhibition of 1889 for his discoveries. 

He died in Frizington, Cumberland in 1906. He had married Lavinia Whitfield, daughter of David Woodward, silk manufacturer of Macclesfield.

Viking SF-2A Cygnet. The Viking SF-2A Cygnet, also called the Sisler SF-2A Cygnet and the HAPI SF-2A Cygnet, is an American STOL amateur-built aircraft, designed by Bert Sisler and produced by Viking Aircraft LLC. The aircraft is supplied in the form of plans for amateur construction. The Cygnet first flew in 1973.

The Cygnet plans were originally marketed by the designer through his company Sisler Aircraft of Bloomington, Minnesota and later by HAPI Engines, a supplier of Volkswagen air-cooled engines. By the 1990s Viking Aircraft of Elkhorn, Wisconsin took over supplying the aircraft plans.

Design and development
The SF-2A Cygnet is a development of the earlier Sisler SF-2 Whistler introduced in 1973. The design features a strut-braced shoulder-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration.

The aircraft is made from wood, 4130 steel tubing and covered in doped aircraft fabric. Its  span wing employs a NACA 3413 airfoil, has an area of  and is supported by a single strut with a jury strut. The cockpit is  wide and has a baggage compartment with a limit of , located behind the seats. The aircraft's recommended engine power range is  and standard engines used include the  Volkswagen four-stroke powerplant. Construction time from the supplied kit is estimated as 1700–1800 hours.

The Cygnet won a design award at the EAA Annual Convention and Fly-In in 1973.

Operational history

By January 2003, 100 examples had been reported as completed and flown.

In July 2016 a total of 19 SF-2A Cygnets were registered in the United States with the Federal Aviation Administration, four with Transport Canada and seven with the Civil Aviation Authority in the United Kingdom.

In a 2020 review, AVweb writer Paul Dye concluded, "Flying a piece of history (and with a forward swept wing, something fairly unique!) is always fun. Just like all strange meat gets described as "tasting like chicken", it is easy to describe airplanes like this as flying "like a Cub"—and it’s true, in the sense that it is well-mannered and easy to steer around the sky. Yes, that visibility at the start of a turn is going to take a little getting used to, as is the landing attitude. But if you take the time to get it figured out, the Cygnet is a nice little airplane with a Midwest tradition. Honest, straightforward, and enjoyable.".

SADI. Semantic Automated Discovery and Integration (SADI) is a lightweight set of fully standards-compliant Semantic Web service design patterns that simplify the publication of services of the type commonly found in bioinformatics and other scientific domains.   SADI services utilize Semantic Web technologies at every level of the Web services "stack".  Services are described in OWL-DL, where the property restrictions in OWL classes are used to define the properties expected of the input and output data.  Invocation of SADI Services is achieved through HTTP POST of RDF data representing OWL Individuals ('instances') of the defined input OWL Class, and the resulting output data will be OWL Individuals of the defined output OWL Class.

SADI design patterns place a single unique constraint on the behaviour of the Service, in that the URI of the input individual, and the URI of the output individual must be identical.  The consequence of this constraint is that the Service provider must connect the output to the input through a defined predicate; effectively, the output is "about" the input, and the relationship between input and output is explicit.  As such, SADI services become the source of new Linked Data, relating the input and output of a service, and chains of SADI services produce uninterrupted Linked Data graphs.

SADI has been used in a number of Bioinformatics data integration case studies
and for semantic querying of relational data in Clinical Informatics settings.

Automatic Transmitter Identification System (marine). The Automatic Transmitter Identification System (ATIS) is a marine VHF radio system used and mandated on navigable inland waterways in Europe for identifying the ship or vessel that made a radio transmission.  The identity of the vessel is sent digitally immediately after the ship's radio operator has finished talking and releases their transceiver's push-to-talk button. This contrasts to the Automatic identification system (AIS) used globally on ships that transmit continuously.  A short post-transmission message is sent by the radio with the vessel identity and is in the form of an encoded call sign or Maritime Mobile Service Identity, starting with number "9" and the three country-specific maritime identification digits.

ATIS use on the Trans-European Inland Waterway network and connecting waterways is mandated by the Regional Arrangement Concerning the Radiotelephone Service on Inland Waterways (RAINWAT) agreements, which also prohibit the use of Digital Selective Calling (DSC) where ATIS is required, except in some near-coastal areas, or in sea-like areas of The Netherlands.

The database of ATIS vessel identities is maintained by the Belgian Institute for Postal Services and Telecommunications (fr) (nl).

The ATIS signalling protocol is based on that used for Digital Selective Calling (DSC); with the ATIS transmissions having the format specifier field set to a value of 121.  While DSC transmissions take place exclusively on Channel 70, the ATIS digital signal is transmitted on the same VHF channel as the voice transmission: it lasts for 285 milliseconds after the PTT button has been released, using frequency modulation frequency-shift keying (FSK) between the frequencies of 1,300 Hz and 2,100 Hz at 1,200 baud.  The core part of the message is transmitted using 10-bit codes; each code being formed of a 7-bit symbol followed by a 3-bit count of the number of zeros in that symbol.

Ablation casting. 

Ablation casting is a variation of a sand casting involving a soluble binder. The mold is dissolved and washed away, allowing rapid cooling of the casting.

Overview 
Ablation casting is a sand casting process that uses water to wash away the mold while the metal solidifies. This process produces castings with high mechanical properties, reduced defects, and a fine microstructure. 

Here are some steps in the ablation casting process:

 Mold preparation: A mold is made from sand particles bonded with a water-soluble binder. 
 Filling: The mold is filled with molten metal. 
 Ablation: While the metal is still molten, a spray of water erodes away the mold. The water allows direct contact with the metal, which eliminates the air gap that usually forms in other casting processes. 

Ablation casting has several advantages, including:

 No fumes or dust  The mold is washed away without producing fumes or dust. 
 High cooling rates  The water spray produces high cooling rates, which results in a fine eutectic microstructure. 
 Directional solidification  The water spray allows for directional solidification, which can help reduce problems with casting alloys. 
 Low porosity  The high temperature gradient and solidification speeds can help eliminate shrinkage porosity. 

Honda used ablation casting to produce the Acura NSX hybrid supercar. Honda chose ablation casting because conventional castings would have been too brittle for the car's crush zones.

The Canadian Forces School of Military Engineering (CFSME), at CFB Gagetown in Oromocto, New Brunswick, is responsible for the conduct of 85 different courses that span all ranks and occupations within the Combat Engineering and Construction Engineering organizations. CFSME is the Canadian Forces centre of excellence in military engineer training.

Originally A6 Canadian Engineering Training Centre, the school was established in Camp Dundurn in Saskatchewan and then moved to Chilliwack, British Columbia, to train military engineers for the Canadian Army during the Second World War.  The A6 Canadian Engineering Training Centre was renamed the Royal Canadian School of Military Engineering. 

In 1968 Canada unified its military forces when it merged the Canadian Army, Royal Canadian Air Force and Royal Canadian Navy to create the Canadian Forces. The Royal Canadian School of Military Engineering was renamed the Canadian Forces School of Military Engineering following unification.  It also found itself responsible for the military engineering training for all services and components of the Canadian Forces.   On the closing of CFB Chilliwack in the late 1990s the school moved to its current location in CFB Gagetown.

The school exists as a unit of the Combat Training Centre and it consists of the following sub-units:
