Analytical Engine

The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, a design for a simpler mechanical computer; the Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. In other words, the logical structure of the Analytical Engine was the same as that which has dominated computer design in the electronic era; the Analytical Engine is one of the most successful achievements of Charles Babbage. Babbage was never able to complete construction of any of his machines due to conflicts with his chief engineer and inadequate funding, it was not until 1941 that the first general-purpose computer, Z3, was built, more than a century after Babbage had proposed the pioneering Analytical Engine in 1837.

Babbage's first attempt at a mechanical computing device, the Difference Engine, was a special-purpose machine designed to tabulate logarithms and trigonometric functions by evaluating finite differences to create approximating polynomials. Construction of this machine was never completed. During this project, he realised that a much more general design, the Analytical Engine, was possible; the work on the design of the Analytical Engine started in c. 1833. The input, consisting of programs and data was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms such as the Jacquard loom. For output, the machine would have a printer, a curve plotter and a bell; the machine would be able to punch numbers onto cards to be read in later. It employed ordinary base-10 fixed-point arithmetic. There was to be a store capable of holding 1,000 numbers of 40 decimal digits each. An arithmetic unit would be able to perform all four arithmetic operations, plus comparisons and optionally square roots.

It was conceived as a difference engine curved back upon itself, in a circular layout, with the long store exiting off to one side. Drawings depict a regularised grid layout. Like the central processing unit in a modern computer, the mill would rely upon its own internal procedures, to be stored in the form of pegs inserted into rotating drums called "barrels", to carry out some of the more complex instructions the user's program might specify; the programming language to be employed by users was akin to modern day assembly languages. Loops and conditional branching were possible, so the language as conceived would have been Turing-complete as defined by Alan Turing. Three different types of punch cards were used: one for arithmetical operations, one for numerical constants, one for load and store operations, transferring numbers from the store to the arithmetical unit or back. There were three separate readers for the three types of cards. Babbage developed some two dozen programs for the Analytical Engine between 1837 and 1840, one program later.

These programs treat polynomials, iterative formulas, Gaussian elimination, Bernoulli numbers. In 1842, the Italian mathematician Luigi Federico Menabrea published a description of the engine based on a lecture by Babbage in French. In 1843, the description was translated into English and extensively annotated by Ada Lovelace, who had become interested in the engine eight years earlier. In recognition of her additions to Menabrea's paper, which included a way to calculate Bernoulli numbers using the machine, she has been described as the first computer programmer. Late in his life, Babbage sought ways to build a simplified version of the machine, assembled a small part of it before his death in 1871. In 1878, a committee of the British Association for the Advancement of Science described the Analytical Engine as "a marvel of mechanical ingenuity", but recommended against constructing it; the committee acknowledged the usefulness and value of the machine, but could not estimate the cost of building it, were unsure whether the machine would function after being built.

Intermittently from 1880 to 1910, Babbage's son Henry Prevost Babbage was constructing a part of the mill and the printing apparatus. In 1910 it was able to calculate a list of multiples of pi; this constituted only a small part of the whole engine. Henry Babbage's "Analytical Engine Mill". Henry proposed building a demonstration version of the full engine, with a smaller storage capacity: "perhaps for a first machine ten would do, with fifteen wheels in each"; such a version could manipulate 20 numbers of 25 digits each, what it could be told to do with those numbers could still be impressive. "It is only a question of cards and time", wrote Henry Babbage in 1888, "... and there is no reason why cards should not be used if necessary, in an Analytical Engine for the purposes of the mathematician". In 1991, the London Science Museum built a complete and working specimen of Babbage's Difference Engine No. 2, a design that incorporated refinements Babbage discovered during the development of the Analytical Engine.

This machine was built using materials and engineering tolerances that would h


KRCB, virtual channel 22, is a Public Broadcasting Service member television station licensed to Cotati, United States and serving the northern portion of the San Francisco Bay Area. Owned by Northern California Public Media, it is a sister station to National Public Radio member KRCB-FM; the two stations share studios on Carlson Avenue in Rohnert Park. KRCB first went on the air in 1984; the station was founded by Nancy Dobbs, president and CEO of KRCB North Bay Public Media, along with other volunteers in the North Bay, including Dobbs' husband, John Kramer. KRCB agreed to move frequencies, while retaining its display channel number, in the FCC auction for $72 million on February 10, 2017. Proceeds will be used to start an endowment. On September 7, 2017, KRCB announced that it would acquire KCSM-TV in San Mateo from the San Mateo County Community College District for $12 million, using some of the money earned in the auction. KRCB relaunched KCSM-TV as KPJK on July 31, 2018. Concurrently with the launch of KPJK, the stations came under the Northern California Public Media banner.

The station's digital signal is multiplexed: KRCB shut down its analog signal, over UHF channel 22, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal relocated from its pre-transition UHF channel 23 to channel 22. In one of the most crowded areas in the U. S. for public broadcasting, KRCB is notable for its coverage of local news and politics, for the Emmy and Telly Award-winning, nationally distributed environmental series, Natural Heroes. KRCB engages the community through local initiatives like North Bay Bountiful, a series of TV, Radio and digital stories that explore agriculture, food systems and environmentalism; the station is known for North Bay Bountiful and Community Health Connections.

And I

"And I" is a song written by American R&B singer Ciara, produced by Adonis Shropshire for Ciara's first album, Goodies. It was released as the album's fourth and final single on August 30, 2005; the song was the third choice for the fourth single. Ciara has mentioned in an interview that "Thug Style", "Hotline" or "Pick up the Phone" would be the fourth single, but when Ciara suggested "And I" to executives at her previous record label LaFace, they were unhappy because they wanted "Next to You" to be the fourth single. At the time of the US release of "And I", Ciara's collaboration with Bow Wow, "Like You", her collaboration with Missy Elliott, "Lose Control", were at the height of their popularity. "And I" peaked at 78 on the US Billboard Hot 100 and 27 on Billboard's Hot R&B/Hip-Hop Singles & Tracks chart, which were poor positions compared to those attained by the first three singles from the album Goodies. It was not released outside North America because of this; the music video for "And I", directed by the Fat Cats, is loosely based on the 1992 Whitney Houston film The Bodyguard.

It takes place on the set of a music video. Carmelo Anthony, playing Ciara's boyfriend, is flirting with another woman while Ciara is filming her music video; when Ciara's bodyguard takes her to visit her boyfriend in her trailer, he opens the door and sees the boyfriend kissing another woman. The bodyguard tells her not to go inside; when she realizes he has been cheating on her, Ciara sits on a log under lights that have been rigged to fall on her. Her bodyguard saves her just before Ciara holds him in her arms.

Giovanni Contarini

Giovanni Contarini was an Italian painter of the late Renaissance. Born in Venice, Contarini was a contemporary of Palma il Giovane, he was a great student of the works of Tintoretto and Titian and is declared to have been an exact imitator of Titian. According to an old story he was so accurate in his portraits that on "sending home one he had taken of Marco Dolce, his dogs began to fawn upon it, mistaking it for their master". Contarini's work is mannered and sweet, but distinguished by beautiful, rich coloring and executed much on the lines of Titian's painting, his finest picture is in the Louvre, having been removed from the ducal palace at Venice, represents the Virgin and Child with St Mark and St Sebastian, the Doge of Venice, Marino Grimani, kneeling before them. Other paintings of his are in the galleries at Berlin, Florence and Vienna, in many of the churches at Venice, he painted easel-pictures of Greek and Roman mythological subjects, which are treated with propriety and discretion but are peculiarly lacking in force and strength.

Some years of his life were passed at the court of the Emperor Rudolf II, with whom he was a great favorite and by whom he was knighted. His work has been described by one writer as a "combination of sugar, mulberry juice and velvet", but the criticism is a little unjust and one or two of his works, for example the "Resurrection" in the church of San Francesco di Paola at Venice, can claim to be masterly; this article incorporates text from a publication now in the public domain: Herbermann, Charles, ed..

Disintegrin and metalloproteinase domain-containing protein 11 is an enzyme that in humans is encoded by the ADAM11 gene. This gene encodes a member of the ADAM protein family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, neurogenesis; this gene represents a candidate tumor suppressor gene for human breast cancer based on its location within a minimal region of chromosome 17q21 defined by tumor deletion mapping.
