John William Dunne

John William Dunne FRAeS (1875–1949) was a British soldier, aeronautical engineer and philosopher. As a young man he fought in the Second Boer War, before becoming a pioneering aeroplane designer in the early years of the 20th century. Dunne worked initially on early military aircraft, concentrating on tailless swept wing designs to achieve the first certified inherently stable aircraft. He later developed a new approach to dry fly fishing before turning to philosophy, where he achieved some pre-eminence and literary influence through his theory on the nature of time and consciousness, which he called "Serialism".

Biography

John William Dunne was born in County Kildare, Ireland, the oldest son of General Sir John Hart Dunne KCB (1835–1924) and Julia Elizabeth Dunne, Anglo-Irish aristocrats. His later life and career was mainly in England.

From an early age he was interested in science and technology and, inspired by a Jules Verne novel, at the age of 13 he dreamed of a flying machine that needed no steering.

D-2 (video)

D-2 is a professional digital videocassette format created by Ampex and introduced at the 1988 NAB (National Association of Broadcasters) convention as a composite video alternative to the component video D-1 format. It garnered Ampex a technical Emmy in 1989. Like D-1, D-2 stores uncompressed digital video on a tape cassette; however, it stores a composite video signal, rather than component video as with D-1. While component video is superior for advanced editing, especially when chroma key effects are used, composite video is more compatible with most existing analog facilities.

History

Ampex created the first D-2 video machine, the ACR-225 commercial spot player working with Sony, who had done some early research into composite digital video, as a cost-effective solution for TV broadcasters with large investments in composite analog infrastructure such as video routers and switchers, since it could be inserted into existing analog broadcast facilities without extensive redesign or modifications. This was because D-2 machines accepted standard analog video and audio inputs and outputs. D-2 machines are capable of interfacing through either serial digital video or analog video connections. Four PCM audio channels are available for editing (an improvement over the then-popular Type C analog machines with two audio channels) as well as an analog cue channel and timecode, also with digital or analog connections.

List of compositions by Franz Schubert by genre

Franz Schubert (31 January 1797 – 19 November 1828) was an extremely prolific Austrian composer. He composed some 1500 works (or, when collections, cycles and variants are grouped, some thousand compositions). The largest group are the lieder for piano and solo voice (over six hundred), and nearly as many piano pieces. Schubert also composed some 150 part songs, some 40 liturgical compositions (including several masses) and around 20 stage works like operas and incidental music. His orchestral output includes a dozen symphonies (seven completed) and several overtures. Schubert's chamber music includes over 20 string quartets, and several quintets, trios and duos.

This article constitutes a complete list of Schubert’s known works organized by their genre. The complete output is divided in eight series, and in principle follows the order established by the Neue Schubert-Ausgabe printed edition. The works found in each series are ordered ascendingly according to Deutsch numbers, the information of which attempts to reflect the most current information with regards to Schubert’s catalogue.
