Bristol Tourer. The Bristol Tourer was a British civil utility biplane produced in the years following the First World War, using as much as possible from the design of the Bristol Fighter aircraft. Bristol Tourers were delivered with a variety of engines, subject to availability and customer desires; these included the Rolls-Royce Falcon, Siddeley Puma, Hispano-Suiza 8, and Wolseley Viper. Many Tourers were fitted with a canopy to cover the one or two passenger seats in the rear cockpit, giving the type its original name of Coupé. The pilot's cockpit, however, remained open.

Bristol Tourers operated by Western Australian Airways made the first scheduled airline services in Australia, commencing on 4 December 1921 between Perth and Geraldton.

Stella (emulator). Stella is an emulator of the Atari 2600 game console, and takes its name from the console's codename. It is open-source, and runs on most major modern platforms including Windows, Mac OS X, and Linux. Stella was originally written in 1996 (and known as Stella 96) by Bradford W. Mott, and is now maintained by Stephen Anthony.

Stella is written in the C++ programming language and thus is highly portable. The emulator supports all Atari 2600 cartridge bank switching schemes and has support for nearly all Atari 2600 titles.  Support is included for NTSC, PAL and SECAM in 60 Hz/50 Hz varieties, including autodetection of those formats (based on the number of scanlines generated in each frame).  It has cycle-exact emulation for the TIA chip (graphics and sound); the Stella Team estimates that current TIA emulation is nearing 100% completion.

Stella emulates most Atari 2600 peripheral devices, including standard joysticks, paddle controllers, the Atari Video Touch Pad, the Atari Keyboard Controller, Atari Indy 500 Driving Controllers, the CBS Booster-Grip controller, the Atari TrakBall/AtariMouse/AmigaMouse trackball controllers, the Sega Genesis controller, and the AtariVox and SaveKey controllers. Stelladaptor and 2600-daptor support allows real joysticks, paddles, and driving controllers to be used, and support is also included to access a real AtariVox device plugged into a serial port (and actually generate sound from the AtariVox device). Stella does not yet support the cassette-based titles designed to work with the Coleco KidVid cassette player but does have support for titles designed to work with the Starpath Supercharger and Spectravideo Compumate.

Stella includes many facilities for homebrew developers, including an extensive built-in interactive debugger and disassembler supporting breakpoints, read/write traps, etc. Other major features include Blargg TV effects, a cheatcode system, support for user-defined palette files, state loading/saving (including a TimeMachine-like unwind/rewind capability), hardware-accelerated rendering and effects, event remapping, and an extensive built-in, cross-platform user interface (including a ROM launcher frontend).

Stella uses the TIA emulation core from 6502.ts, a collection of emulators for MOS 6502 based systems written in TypeScript and runnable from a web page.

KAOS (software development). KAOS, is a goal-oriented software requirements capturing approach in requirements engineering. It is a specific Goal modeling method; another is i*. It allows for requirements to be calculated from goal diagrams. KAOS stands for Knowledge Acquisition in automated specification or Keep All Objectives Satisfied. 

The University of Oregon and the University of Louvain (Belgium) designed the KAOS methodology in 1990 by Axel van Lamsweerde and others. It is taught worldwide at the university level  for capturing software requirements.

There is lack of evidence that KAOS is used in the industry and as of February 2023, the only tool supporting it is Objectiver, written by the same group behind the KAOS methodology, with the latest release 3.0c47 dated at March 9th, 2012.

Quantum dimer models. Quantum dimer models were introduced to model the physics of resonating valence bond (RVB) states in lattice spin systems.  The only degrees of freedom retained from the motivating spin systems are  the valence bonds, represented as dimers which live on the lattice bonds.  In typical dimer models, the dimers do not overlap ("hardcore constraint").

Typical phases of quantum dimer models tend to be valence bond crystals.  However, on non-bipartite lattices,  RVB liquid phases possessing topological order and fractionalized spinons also appear.  The discovery of topological order in quantum dimer models (more than a decade after the models were introduced) has led to new interest in these models.

Classical dimer models have been studied previously in statistical physics, in particular by P. W. Kasteleyn (1961) and
M. E. Fisher (1961).

Alfred Burges. Alfred Burges (1796–1886) was a British civil engineer.  He was apprenticed to the civil engineer James Walker, and in turn trained several other engineers including Sir Joseph Bazalgette.

Walker and Burges were responsible for railways, bridges and many marine works, including 21 lighthouses, Surrey Commercial Docks, the Junction Dock at Hull, and the Bedford Levels. Their firm is noted in many documents as Messrs. Walker & Burgess, engineers of Limehouse, with his last name being almost always spelt in this way.

He died at Worthing on 12 March 1886, and is buried at West Norwood Cemetery. He left a fortune of £113,000.(£ in  adjusted for inflation)

His son William (1827–1881) was an influential architect.

JBoss Seam. Seam was a web application framework developed by JBoss, a division of Red Hat.

Seam 3 
Seam 3 provides a modular set of extensions to the CDI programming model. Seam's mission is to provide a fully integrated development platform for building rich, standards-based Internet applications tailored for traditional and cloud deployments. Seam 3 is intended to be a more scalable, feature rich set of extensions than Seam 2, which is under maintenance development only.

Seam sources on GitHub have not been updated since September 2012. Active development of Seam 3 has been halted by Red Hat.

Seam 2

Seam 2 combines the two frameworks Enterprise JavaBeans (EJB3) and JavaServer Faces (JSF). However, simple POJOs can be used at the back end. One can turn any EJB3 object or any simple POJO object into a seam component by just using annotations. Once a component becomes a seam component, it can be accessed through JSF or through other business-logic components in a unified manner. Thus, one can access any back-end EJB component from the front-end by addressing it by its Seam component name. This Java web framework incorporates identity management features.

Seam 2 introduces the concept of bijection, taken from Spring's dependency injection feature, where objects can be in-jected or out-jected to/from assigned variables using the @In and @Out annotations.

The framework also expands the concept of contexts. Each seam component exists within a context. The default Seam context, a conversation, can span multiple pages and usually spans the whole business flow, from start to finish. The session context captures all actions of a user until he/she logs out or closes the browser - even across multiple uses of the browser back-button.

One can automatically generate a CRUD (create-read-update-delete) web-application from an existing database using the command-line tool seam-gen supplied with the framework.

Seam facilitates WYSIWYG development through the use of JBoss Tools, a set of plug-ins targeted at the open-source Eclipse integrated development environment.

Seam integrates out of the box with the RichFaces and ICEfaces Ajax libraries, as well as with many other Ajax libraries - without the need to write JavaScript code.

Seam also includes creator modules for PDF documents, e-mail, graphs, and Microsoft Excel worksheets.

Allen Coombs. Allen William Mark (Doc) Coombs (23 October 1911 – 30 January 1995) was a British electronics engineer at the Post Office Research Station, Dollis Hill. 
 
Coombs was one of the principal designers of the Mark II or production version of the Colossus computer used at Bletchley Park for codebreaking in World War II, and took over leadership of the project when Tommy Flowers moved on to other projects. Professor Brian Randell was researching the history of computer science in Britain for a conference on the history of computing held at the Los Alamos National Laboratory, New Mexico on 10-15 June 1976, and got permission to present a paper on wartime development of the COLOSSI  at the Post Office Research Station,  Dollis Hill (in October 1975 the British Government released a series of captioned photographs from the Public Record Office).  The interest in the “revelations” in his paper resulted in a special evening meeting when Randell and Cooombs answered further questions. Coombs later wrote that no member of our team could ever forget the fellowship, the sense of purpose and, above all, the breathless excitement of those days. In 1977 Randell published an article The First Electronic Computer in several journals.  

Later at Dollis Hill Coombs worked on the MOSAIC machine. Coombs headed the scientific side of R14, the division working on optical character recognition for postal mechanisation, which moved to the new BT Research Centre at Martlesham in Suffolk. His work on pattern recognition led to the development of an early postcode-reading machine.

He frequently lectured on pattern recognition using the concept of multi-dimensional space, and the 'caltrop', and would demonstrate the presence of feature-detection in the human visual system by means of a flash gun, the persistence of vision in the audience leading them to observe disintegration of a character fragment by fragment. 'Doc' Coombs was notable for a facial 'tic', which gave him something of the appearance of the 'mad professor', and these days would probably be classed under Tourette's syndrome.

Pressure angle. Pressure angle in relation to gear teeth, also known as the angle of obliquity, is the angle between the tooth face and the gear wheel tangent. It is more precisely the angle at a pitch point between the line of pressure (which is normal to the tooth surface) and the plane tangent to the pitch surface. The pressure angle gives the direction normal to the tooth profile.  The pressure angle is equal to the profile angle at the standard pitch circle and can be termed the "standard" pressure angle at that point.  Standard values are 14.5 and 20 degrees. Earlier gears with pressure angle 14.5 were commonly used because the cosine is larger for a smaller angle, providing more power transmission and less pressure on the bearing; however, teeth with smaller pressure angles are weaker. To run gears together properly their pressure angles must be matched.

The pressure angle is also the angle of the sides of the trapezoidal teeth on the corresponding rack.
The force transmitted during the mating of gear teeth acts along the normal. This force has components along the pitch line and the other along the line perpendicular to the pitch line. The force along the pitch line which is responsible for power transmission is proportional to the cosine of pressure angle. The one which exerts thrust (perpendicular to the pitch line) is proportional to the sine of pressure angle. So it is advised to keep the pressure angle low.

Just as there are three types of profile angle, there are three types of corresponding pressure angle: the transverse pressure angle, the normal pressure angle, and the axial pressure angle.

Philip Dalton. Lt. Philip Dalton (April 1, 1903 – July 25, 1941) was a United States military scientist, pilot and engineer.  Dalton is best known for his invention of several slide-rule analog flight computers, the most famous being the E6B.

Dalton was born in Scotia, New York, to William and Ida Dalton.

He studied engineering at Cornell University's College of Engineering, where he joined the ROTC.  Upon graduation, he received a commission as a lieutenant of field artillery in the United States Army Reserve. He continued his studies at Princeton University, where he received a master's degree in physics, and Harvard, after which he resigned his Army commission and joined the United States Naval Reserve. He received his wings at NAS Pensacola, and flew scout planes on the cruiser Northampton.

While serving as US Naval Reserve Pilot, Dalton took an interest in slide-rule flight computers.  His first models were designed in the early 1930s, but in 1932 his first version of the E-6B, originally known as the "Dalton Dead Reckoning Computer", came into existence.

On October 30, 1940, Dalton was recalled to active duty and assigned to Naval Air Station Anacostia, across the river from Washington, DC, to help train naval aviators. On July 24, 1941, Dalton and Harry Lee Rogers, Jr., a student pilot, were killed when their aircraft crashed near Hybla Valley, Virginia. By this time, Dalton's devices were in widespread use by all aviation branches of the US and British military services.
