IRENE (technology)
IRENE (''Image, Reconstruct, Erase Noise, Etc.'') is a digital imaging technology designed to recover analog audio stored on fragile or deteriorating phonograph cylinders, records, and other grooved audio media. It is in use by several archives and preservation institutions in the United States seeking to preserve and digitize historical audio. History The technology was developed at Lawrence Berkeley National Laboratory by Carl Haber and Vitaliy Fadeyev and was announced in a publication of the ''Journal of the Audio Engineering Society'' in 2003.Vitaliy Fadeyev and Carl Haber, ''Reconstruction of Mechanically Recorded Sound by Image Processing''. ''Journal of the Audio Engineering Society'', 2003.PDF It grew out of Haber's research in particle physics; in the 1990s, he had worked on Higgs boson detection experiments, and realized that the cameras he was using to set the detectors could also be used for detailed imaging of grooved audio recordings. The name IRENE is a backronym of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Imaging
Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality. Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image. For example, the medium of visible light allows digital photogra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast Document Conservation Center
The Northeast Document Conservation Center (NEDCC) is the first non-profit conservation center in the United States to specialize in the preservation of paper-based library and archival materials, founded in 1973. The Center was initiated by the state librarians of the six New England states, who agreed to cooperate across state lines to provide a service to non-profit institutions in the region. The Center was established with start-up funds from the Council on Library Resources, the New England Library Board, and other donors. For seven years the Center functioned as an arm of the New England Library Board. In 1980, it incorporated as a private, non-profit organization, providing services to clients nationally. NEDCC performs book conservation, paper conservation, photograph conservation, Asian paintings conservation, collections surveys, digitization, and audio preservation with the IRENE technology, on a fee-for-service basis. Through its Preservation Services office, N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Languages Of The Americas
Over a thousand indigenous languages are spoken by the Indigenous peoples of the Americas. These languages cannot all be demonstrated to be related to each other and are classified into a hundred or so language families (including a large number of language isolates), as well as a number of extinct languages that are unclassified because of a lack of data. Many proposals have been made to relate some or all of these languages to each other, with varying degrees of success. The most notorious is Joseph Greenberg's Amerind hypothesis, which however nearly all specialists reject because of severe methodological flaws; spurious data; and a failure to distinguish cognation, contact, and coincidence. Nonetheless, there are indications that some of the recognized families are related to each other, such as widespread similarities in pronouns (e.g., ''n''/''m'' is a common pattern for 'I'/'you' across western North America, and ''ch''/''k''/''t'' for 'I'/'you'/'we' is similarly ...

Wax Cylinder
Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of different types are produced by plants and animals and occur in petroleum. Chemistry Waxes are organic compounds that characteristically consist of long aliphatic alkyl chains, although aromatic compounds may also be present. Natural waxes may contain unsaturated bonds and include various functional groups such as fatty acids, primary and secondary alcohols, ketones, aldehydes and fatty acid esters. Synthetic waxes often consist of homologous series of long-chain aliphatic hydrocarbons (alkanes or paraffins) that lack functional groups. Plant and animal waxes Waxes are synthesized by m ...

Edison Company
The Edison Manufacturing Company, originally registered as the United Edison Manufacturing Company and often known as simply the Edison Company, was organized by inventor and entrepreneur Thomas Edison and incorporated in New York City in May 1889. It succeeded the Edison United Manufacturing Company, founded in 1886 as a sales agency for the Edison Lamp Company, Edison Machine Works, and Bergmann & Company, which made electric lighting fixtures, sockets, and other accessories. In April 1894, the Edison laboratory's Kinetoscope operation, which was about to be commercialized, was brought under the Edison Company umbrella. In 1900, the United Edison Manufacturing Company was evidently succeeded by the New Jersey–incorporated Edison Manufacturing Company. The company's assets and operations were transferred to Thomas A. Edison, Inc. in 1911. History The Edison United Manufacturing Company was incorporated in July 1886 to consolidate the sales operations of the various Edison ma ...

Alexander Graham Bell
Alexander Graham Bell (, born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born inventor, scientist and engineer who is credited with patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885. Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf; profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Bell also had a strong influence on the National Geographic Society and it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volta Laboratory
The Volta Laboratory (also known as the Alexander Graham Bell Laboratory, the Bell Carriage House and the Bell Laboratory) and the Volta Bureau were created in Georgetown, Washington, D.C. by Alexander Graham Bell.(19/20th-century scientist and inventor best known for his work on the telephone) The Volta Laboratory was founded in 1880–1881 with Charles Sumner Tainter and Bell's cousin, Chichester Bell, for the research and development of telecommunication, phonograph and other technologies. Using funds generated by the Volta Laboratory, Bell later founded the Volta Bureau in 1887 "for the increase and diffusion of knowledge relating to the deaf", and merged with the American Association for the Promotion and Teaching of Speech to the Deaf (AAPTSD) in 1908. It was renamed as the Alexander Graham Bell Association for the Deaf in 1956 and then the Alexander Graham Bell Association for the Deaf and Hard of Hearing in 1999.

Au Clair De La Lune
"" (, ) is a French folk song of the 18th century. Its composer and lyricist are unknown. Its simple melody () is commonly taught to beginners learning an instrument. Lyrics The song appears as early as 1820 i''Le Voiture Verseés'' with only the first verse. Four verses were later re-published in the 1858 compilation ''Chants et Chansons populaires de la France''. In the 1870 compilation ''Chansons et Rondes Enfantines'', only the first two verses of the original four were retained. Some sources report that "plume" (pen) was originally "lume" (an old word for "light" or "lamp"). Much of the lyrics has sexual innuendos. In music 19th-century French composer Camille Saint-Saëns quoted the first few notes of the tune in the section "The Fossils", part of his suite '' The Carnival of the Animals''. French composer Ferdinand Hérold wrote a set of variations for piano solo in E-flat major. Claude Debussy, composer of the similarly named "Clair de lune" from his ''Suite be ...

Édouard-Léon Scott De Martinville
Édouard-Léon Scott de Martinville (; 25 April 1817 – 26 April 1879) was a French printer, bookseller and inventor. He invented the earliest known sound recording device, the phonautograph, which was patented in France on 25 March 1858 . Early years Scott de Martinville was of Scottish descent. His ancestors came from Scotland and moved to Brittany in the seventeenth century. As a printer by trade, he was able to read accounts of the latest scientific discoveries and became an inventor. Scott de Martinville was interested in recording the sound of human speech in a way similar to that achieved by the then-new technology of photography for light and image. He hoped for a form of stenography that could record the whole of a conversation without any omissions. His earliest interest was in an improved form of stenography, and he was the author of several papers on shorthand and a history of the subject (1849). He was married twice and had six children.

Lacquer Disc
An acetate disc (also known as a ''lacquer'', ''test acetate'', ''dubplate'', or ''transcription disc'') is a type of phonograph record generally used from the 1930s to the late 1950s for recording and broadcast purposes and still in limited use today. Acetate discs are used for the production of records. Unlike ordinary vinyl records, which are quickly formed from lumps of plastic by a mass-production molding process, an acetate disc is created by using a recording lathe to cut an audio-signal-modulated groove into the surface of a lacquer-coated blank disc, a sequential operation requiring expensive, delicate equipment and expert skill for good results. The disc is then coated in metal, which is then peeled off to form a negative that will later be electroplated and peeled to create a mother (positive copy) which is then again electroplated and peeled to create negatives called stampers, which are then used as molds in a record press. In addition to their use in the creation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wired (magazine)
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online magazine, online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including ''Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophon (publishing), colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
