David Hay (engineer). David Hay (10 April 1859 – 30 October 1938) was a British civil engineer of the late 19th and early 20th centuries, particularly associated with design of bridges and tunnels.

Biography
Hay was born in Casterton, Westmoreland in north-west England on 10 April 1859. He worked initially as a pupil of his father and was subsequently appointed as contractor's engineer on the construction of the Great Northern and London and North Western Railway joint line from Newark to Tilton and Leicester. During 1884 and 1885 he worked on a new dock at Silloth, near Carlisle, before spending three years on widening North Eastern Railway lines in and near Newcastle-upon-Tyne.

He then became a protégé of Sir Benjamin Baker, working with him on the first Blackwall Tunnel in the 1890s, about which he wrote a paper with Maurice Fitzmaurice published by the Institution of Civil Engineers in 1897. The paper resulted in awards of Watt Medals and Telford Premiums to the authors.

With his business partner Basil Mott (in 1902, they formed a consulting engineering practice, Mott and Hay - later Mott, Hay and Anderson), Hay was involved with the design and construction of London's first deep level "tube" lines - the City and South London Railway (today part of the Northern line) and the Central London Railway (today forming the Central line between Shepherd's Bush and the City of London). Mott and Hay were internationally recognised as authorities on underground railways, being invited to write a 1905 paper for the American Society of Civil Engineers.

They were also involved with modernisation work on London bridges including Southwark Bridge and Blackfriars Bridge, the Tyne Bridge in Newcastle-upon-Tyne, and the first of the Mersey Tunnels, the Queensway Tunnel. In 1912, David Hay visited Australia to advise on a possible harbour crossing in Sydney.

He died at Flimwell Grange, near Hawkhurst, Kent, on 30 October 1938.

Fairhurst (company). Fairhurst (formerly F.A. Macdonald & Partners and then W. A. Fairhurst & Partners) is a Scottish engineering consultancy business. It takes its name from William Fairhurst, a notable bridge designer who led the partnership for 30 years.

History
The business was founded by Frank A. Macdonald in Glasgow in 1902, and initially provided design and construction in ferro-concrete (reinforced concrete) using a system patented by French engineer, François Hennebique. Significant early projects included the Usher Hall in Edinburgh.

William Fairhurst joined the company in 1931, having established his reputation as a civil and structural engineer, and became a director in 1938 and managing director in 1941.

The firm, meanwhile, began to expand its network of offices, both organically and through acquisition, opening Scottish bases in Aberdeen, Edinburgh, Dundee and Elgin, and then English offices in places including Newcastle, Leeds, London (from 1982 to 1997, the company was project manager for the implementation of the engineering infrastructure for the London Docklands Development Corporation) and Bristol. Overseas project offices were also established at various times.

However, a domestic project awarded in 1959, the new Tay Road Bridge, crossing the Tay estuary and linking north-east Fife with Dundee, proved pivotal in the firm's development, and the key involvement of Fairhurst led the business to change its name to W. A. Fairhurst and Partners. Fairhurst retired in 1971, by which time the business had delivered another major Scottish bridge: the Kingston Bridge, Glasgow (1970).

Today
The engineering consultancy today works out of 15 principal offices and employs 500 staff. Today it is one of the largest private consultancy companies in the UK, trading since 1 January 2012 under the name Fairhurst.

Ultimate Jetwing. The Ultimate Jetwing is an American ultralight trike that was designed and produced by Ultimate Flight Designs of Mounds, Oklahoma. The aircraft was supplied fully assembled.

Design and development
The Jetwing was one of the first trikes to be made commercially available, being introduced in 1981. The initial versions used a single surface Rogallo wing. The type went out of production in the mid-1980s, but was reintroduced by the original manufacturer in the late 1990s, using a much newer wing design, a double-surface Demon wing.

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The aircraft has a standard empty weight of . It features a minimalist design, cable-braced hang glider-style high wing, weight-shift controls, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its wing covered in Dacron sailcloth. Its  area Demon wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The landing gear employs large-diameter plastic-rimmed wheels to save weight and has suspension on all three wheels. Mainwheel suspension is of the swing-axle and bungee type, while the nosewheel uses a steel spring. A wide variety of small engines can be used, including the Kawasaki 440 twin-cylinder, two-stroke snowmobile engine.

Because of its light weight and low wing loading the Jetwing is suitable for power-off soaring flight.

Knudsen equation. In fluid dynamics, the Knudsen equation is used to describe how gas flows through a tube in free molecular flow.  When the mean free path of the molecules in the gas is larger than or equal to the diameter of the tube, the molecules will interact more often with the walls of the tube than with each other. For typical tube dimensions, this occurs only in high or ultrahigh vacuum.

The equation was developed by Martin Hans Christian Knudsen (1871–1949), a Danish physicist who taught and conducted research at the Technical University of Denmark.

Cylindrical tube
For a cylindrical tube, the Knudsen equation is:

For nitrogen (or air) at room temperature, the conductivity  (in liters per second) of a tube can be calculated from this equation:

Natural predictive dialing. Natural predictive dialing is a technology, developed to eliminate problems typically associated with predictive dialing. These issues include abandoned calls, initial call delays, government regular, and consumer dissatisfaction, among others.

At its core, natural predictive dialing technologies are based on the concept that call automation should work with agents, instead of call automation working before agents are connected. 

In natural predictive dialing, the call automation [sometimes called Call Progress Analysis (CPA)] can work before, during, or after a caller has interfered with a call.  This interweaving of automation and human agents provides productivity increase and works to eliminate the unnatural effect that many call automation technologies have on the human interaction aspects of the call.

Benefits 
In natural predictive dialing, the agents hear the called party say "hello" and can respond accordingly.  The technology is deployed on small and large scales (one user up to thousands).  Contact centers aiming for a natural calling experience and increased productivity might use this technology.

Drawbacks 
The only commercially available natural predictive dialer is provided by a single vendor.  Additionally, patents protecting the technology make it more expensive than many other systems, such as those available for free based on the Asterisk platform.

Sage Type 4. The Sage Type 4 was a prototype British floatplane of the First World War. It was a designed as a two-seat reconnaissance aircraft for the Royal Naval Air Service, but was chosen for service as a floatplane trainer, although the end of the war resulted in production being cancelled.

Design and development
In early 1917, the Peterborough based woodworking company of Frederick Sage & Company designed a two-seat patrol floatplane for the Royal Naval Air Service based on Sage's Type 3 landplane trainer. Like the Type 3, the new design, the Sage Type 4, was a single-engined biplane. Pilot and observer sat in separate tandem cockpits, with the pilot occupying the front cockpit, while the wireless operator/observer sat in the rear cockpit, with both crew members having good visibility. The aircraft was powered by a single 150 hp (112 kW) Hispano-Suiza 8 water-cooled V-8 engine in the nose driving a tractor propeller. Undercarriage consisted of two main floats under the wing the a further tail float.

The prototype Sage Type 4a (serial number N.116) first flew on 3 July 1917. The type demonstrated excellent handing during testing, being capable both of flying aerobatic manoeuvres while still being stable enough to be easily flown "hands-off". Despite this, the type was rejected for service as a patrol aircraft, but it was recommended that it instead be adapted into a float-plane trainer. The aircraft was fitted with dual controls and the engine mounting was modified to allow any one of a variety of 200 hp (149 kW) engines to be fitted. N.116 was converted to the new standard, being fitted with a Sunbeam Arab and flew as the Sage Type 4b on 17 May 1918.

Sage also designed a revised version, the Sage Type 4c with folding wings of increased wingspan (39 ft  in (12.07 m) compared with 34 ft 6 in (10.52 m) for the earlier aircraft and powered by a 200 hp Hispano Suiza engine, with a prototype flying on 12 October 1918.

Both the Type 4b and 4c were adopted as standard training floatplanes for the RNAS, but the end of the First World War resulted in production plans being abandoned.

Variants
Type 4a
Two-seat patrol seaplane, powered by  Hispano-Suiza 8A engine. One prototype built. Converted to Type 4b.

Sage Bionetworks. Sage Bionetworks is a nonprofit organization in Seattle that promotes open science and patient engagement in the research process. It is led by Luca Foschini. It was co-founded by Stephen Friend and Eric Schadt.

Open science
Sage Bionetworks is notable for being an early advocate of open science. The company operates a software platform for collaborative data analysis called Synapse that allows researchers to work together on data curation and computational modeling asynchronously in a manner inspired by GitHub. Synapse also serves as the software infrastructure for running computational challenges. Sage is also developing a citizen-science platform called Bridge.

Research
The bulk of Sage's scientific results emerge from cancer and neurosciences, with notable contributions to the Cancer Genome Atlas Pan-Cancer project. Another Sage initiative, The Resilience Project describes itself as a search for individuals who have genetic changes expected to cause severe illness but who remain perfectly healthy. The hope is to yield insight into factors that protect these individuals from disease. In 2019 Sage Bionetworks has joined Open-AD Drug Discovery Center, which aims to find new Alzheimer's drugs. “This project stitches together open science approaches in computational and experimental research,” Sage president Dr. Lara Mangravite said in a statement.

History
Sage Bionetworks was founded in 2009 as a spinout of Merck & Co., who released software, hardware, intellectual property, and staff connected to its Rosetta Inpharmatics unit. A donation from Quintiles provided early funding.

In March 2011 Sage partnered with CHDI Foundation to develop computer simulations for studying Huntington's disease.  At the same time Sage also announced a partnership with Takeda Pharmaceutical Company wherein Sage would do research to identify biological targets for central nervous system diseases.

In February 2013, Sage Bionetworks partnered with the Dialogue on Reverse Engineering Assessment and Methods (DREAM) project to provide expertise and infrastructure for DREAM Challenges on the Synapse.org platform.

In September 2019, Sage announced a partnership with Cornell Tech, the University of California, San Francisco, Open mHealth and The Commons Project to develop an electronic health data management program called CommonHealth. The program would use Health Level Seven International standards for compatibility with both Apple Health and a similar app on Android devices.

Triple Alpha Luftfahrtgesellschaft. Triple Alpha Luftfahrtgesellschaft GmbH was a German charter airline and aircraft management company headquartered in Düsseldorf and based at Düsseldorf Airport. Since 2009, it had been a subsidiary of Ocean Sky.

History

Hans Pfeiffer and Erik Scheidt, who both worked in overhaul and maintenance of Cessna T303 aircraft in Aachen, founded Avanti Aviation Aachen Luftfahrtgesellschaft in 1995. The newly established airline obtained its AOC in 1996 and started operations with two Cessna 421 aircraft, followed by its first jet aircraft, a Cessna Citation II a year later and the first turboprop aircraft, a Piper Cheyenne, in 1998.

Also in 1998, the airline was relocated to Düsseldorf and renamed Triple Alpha Luftfahrtgesellschaft, sometimes shortended to 3A.

In 2001, the first Cessna Citation CJ2 approved in Europe was delivered to Triple Alpha. In the same year, due to economic downturn following the September 11 attacks, the airline reduced its frequencies and was forced to store some of their aircraft and slow down expansion in the upcoming years.

In 2005, a Cessna Citation V was registered in France and based in Paris. A year later, Triple Alpha which then operated a fleet of nine Cessna Citation aircraft, ordered a larger Airbus A319CJ. Additionally, the fleet was expanded in the following years with Challenger 300, Bombardier Global 7000 and Cessna Citation Mustang mid- and long-range aircraft.

In September 2009, business jet operator Ocean Sky acquired a 60 percent stake in Triple Alpha, this was increased to 80 percent a year later. Also during 2010 and 2011, the airline received their first two IAI Astra aircraft.

However, in July 2011, Triple Alpha filed for insolvency and was put under control of an administrator appointed by a German court.

Destinations
Triple Alpha did not offer scheduled services but operated charter, general aviation, business, cargo, flight school, air ambulance, aerial evacuation and organ transport services.

Fleet

The Triple Alpha fleet consisted of the following aircraft:

 1 Airbus A319CJ
 1 Bombardier Challenger 300
 1 Bombardier Global 7000
 2 Cessna Citation II
 2 Cessna Citation V
 8 Cessna Citation CJ2
 1 Cessna Citation Mustang
