Testbed
A testbed (also spelled test bed) is a platform for conducting rigorous, transparent, and replicable testing of scientific theories, computational tools, and new technologies. The term is used across many disciplines to describe experimental research and new product development platforms and environments. They may vary from hands-on prototype development in manufacturing industries such as automobiles (known as " mules"), aircraft engines or systems and to intellectual property refinement in such fields as computer software development shielded from the hazards of testing live. Software development In software development, testbedding is a method of testing a particular module (function, class, or library) in an isolated fashion. It may be used as a proof of concept or when a new module is tested apart from the program/system it will later be added to. A skeleton framework is implemented around the module so that the module behaves as if already part of the larger program. ...

Testbed Aircraft
A testbed aircraft is an aeroplane, helicopter or other kind of aircraft intended for flight research or testing the aircraft concepts or on-board equipment. These could be specially designed or modified from serial production aircraft. Use of testbed aircraft For example, in development of new aircraft engines, these are fitted to a testbed aircraft for flight testing, before certification. For this adaptation it is required, among other changes, that new instrumentation wiring and equipment, fuel system and piping, as well as structural modifications of wing. The Folland Fo.108 (nicknamed the "Folland Frightful") was a dedicated engine testbed aircraft of the 1940s. The aircraft had a mid fuselage cabin for test instrumentation and observers. Twelve were built and provided to British aero-engine companies. A large number of aircraft-testbeds have been produced and tested since 1941 in the USSR and Russia by the Gromov Flight Research Institute. AlliedSignal, Honeywell Aeros ...

Arena (web Browser)
The Arena browser (also known as the Arena WWW Browser) was one of the first web browsers for Unix. Originally begun by Dave Raggett in 1993, development continued at CERN and the World Wide Web Consortium (W3C) and subsequently by Yggdrasil Computing. Arena was used in testing the implementations for HTML version 3.0, Cascading Style Sheets (CSS), Portable Network Graphics (PNG), and libwww. Arena was widely used and popular at the beginning of the World Wide Web. Arena, which predated Netscape Navigator and Microsoft's Internet Explorer, featured a number of innovations used later in commercial products. It was the first browser to support background images, tables, text flow around images, and inline mathematical expressions. The Arena browser served as the W3C's testbed browser from 1994 to 1996 when it was succeeded by the Amaya project. History In 1993, Dave Raggett, then at Hewlett-Packard (HP) in Bristol, England devoted his spare time to developing Arena on which ...

Libwww
Libwww was an early World Wide Web software library providing core functions for browsers, implementing HTML, HTTP, and other technologies. Tim Berners-Lee, at CERN, released libwww (then also called the "Common Library") in late 1992, comprising reusable code from the first browsers (WorldWideWeb and Line Mode Browser). Libwww was relied upon by the popular browser Mosaic. By 1997, however, interest in libwww declined, and the W3C (which took over from CERN) reduced its commitment to the project. Later, the purpose of libwww was redefined to be "a testbed for protocol experiments", and in that vein it was maintained for the benefit of the W3C's standards-promoting browser Amaya. Active development of libwww stopped in 2000. libcurl is considered to be a modern replacement for libwww. History In 1991 and 1992, Tim Berners-Lee and a student at CERN named Jean-François Groff rewrote various components of the original WorldWideWeb browser for the NeXTstep operating system in p ...

Development Mule
A development mule (test mule, or simply mule) in the automotive industry is a testbed vehicle equipped with prototype components requiring evaluation. They are often camouflaged to cover their designs. Application Mules are necessary because automakers must assess new aspects of vehicles for both strengths and weaknesses before production. Mules are drivable, often pre-production, vehicles, sometimes years away from realization and coming after a concept car that preceded the design of critical mechanical components. Some are built to function as test beds for entry into new market segments such as the mid-engined test mules developed in Italy and Germany for American Motors (AMC). Surviving examples are unique. Mules may also have advanced chassis and powertrain designs from a prospective vehicle that need testing, which can be effectively concealed in the body and interior of a similarly sized production model. In some cases, a completely unrelated vehicle is adapted to hide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Bird (aviation)
An iron bird is a ground-based test device used for prototyping and integrating aircraft systems during the development of new aircraft designs. Aircraft systems are installed into the iron bird so their functions can be tested both individually and in correlation with other systems. Overview Iron birds are used for system integration, reliability testing, and shakedown testing of aircraft systems such as landing gear, avionics, hydraulics, and flight controls. The components may be arranged roughly in the same layout as they will be in the final aircraft design, but left accessible for ease of maintenance. Some iron birds also include a flight deck so that testing can include pilot inputs and simulated flight profiles, and can be used in pre-flight pilot training. Others are used for testing of propulsion systems. Iron birds can also be used after aircraft certification for troubleshooting ongoing issues and for testing of proposed modifications prior to fleet integration. ...

Avro Lancaster
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive-bombing attacks. Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one of the versions, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amaya (web Browser)
Amaya (formerly Amaya World) is a discontinued free and open source WYSIWYG web authoring tool with browsing abilities. It was created by a structured editor project at the INRIA, a French national research institution, and later adopted by the World Wide Web Consortium (W3C) as their testbed for web standards; a role it took over from the Arena web browser. Since the last release in January 2012, INRIA and the W3C have stopped supporting the project and active development has ceased. Amaya has relatively low system requirements, even in comparison with other web browsers from the era of its active development period, so it has been considered a "lightweight" browser. History Amaya originated as a direct descendant of the ''Grif'' WYSIWYG SGML editor created in the early 1980s, and of the HTML editor Symposia, itself based on Grif, both developed and sold by French software company Grif SA. The last change of code of Amaya was on 22 Feb 2013. Features * Access keys * Caret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''prototype'' derives from the Greek , "primitive form", neutral of , "original, primitive", from πρῶτ� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cascading Style Sheets
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language such as HTML or XML (including XML dialects such as SVG, MathML or XHTML). CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript. CSS is designed to enable the separation of content and presentation, including layout, colors, and fonts. This separation can improve content accessibility; provide more flexibility and control in the specification of presentation characteristics; enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, which reduces complexity and repetition in the structural content; and enable the .css file to be cached to improve the page load speed between the pages that share the file and its formatting. Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering ...

Aviation Week
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
