Multiplexer

In electronics, a multiplexer known as a data selector, is a device that selects between several analog or digital input signals and forwards it to a single output line. A multiplexer of 2 n inputs has n select lines, which are used to select which input line to send to the output. Multiplexers are used to increase the amount of data that can be sent over the network within a certain amount of time and bandwidth. Multiplexers can be used to implement Boolean functions of multiple variables. An electronic multiplexer makes it possible for several signals to share one device or resource, for example, one A/D converter or one communication line, instead of having one device per input signal. Conversely, a demultiplexer is a device taking a single input and selecting signals of the output of the compatible mux, connected to the single input, a shared selection line. A multiplexer is used with a complementary demultiplexer on the receiving end. An electronic multiplexer can be considered as a multiple-input, single-output switch, a demultiplexer as a single-input, multiple-output switch.

The schematic symbol for a multiplexer is an isosceles trapezoid with the longer parallel side containing the input pins and the short parallel side containing the output pin. The schematic on the right shows a 2-to-1 multiplexer on the left and an equivalent switch on the right; the s e l wire connects the desired input to the output. One use for multiplexers is economizing connections over a single channel, by connecting the multiplexer's single output to the demultiplexer's single input; the image to the right demonstrates this benefit. In this case, the cost of implementing separate channels for each data source is higher than the cost and inconvenience of providing the multiplexing/demultiplexing functions. At the receiving end of the data link a complementary demultiplexer is required to break the single data stream back down into the original streams. In some cases, the far end system may have functionality greater than a simple demultiplexer; this would be typical when: a multiplexer serves a number of IP network users.

A multiplexer and demultiplexer are combined together into a single piece of equipment, conveniently referred to as a "multiplexer". Both circuit elements are needed at both ends of a transmission link because most communications systems transmit in both directions. In analog circuit design, a multiplexer is a special type of analog switch that connects one signal selected from several inputs to a single output. In digital circuit design, the selector wires are of digital value. In the case of a 2-to-1 multiplexer, a logic value of 0 would connect I 0 to the output while a logic value of 1 would connect I 1 to the output. In larger multiplexers, the number of selector pins is equal to ⌈ log 2 ⁡ ⌉ where n is the number of inputs. For example, 9 to 16 inputs would require no fewer than 4 selector pins and 17 to 32 inputs would require no fewer than 5 selector pins; the binary value expressed on these selector pins determines the selected input pin. A 2-to-1 multiplexer has a boolean equation where A and B are the two inputs, S 0 is the selector input, Z is the output: Z = ∨ Which can be expressed as a truth table: Or, in simpler notation: These tables show that when S 0 = 0 Z = A but when S 0 = 1 Z = B.

A straightforward realization of this 2-to-1 multiplexer would need 2 AND gates, an OR gate, a NOT gate. While this is mathematically correct, a direct physical implementation would be prone to race conditions that require additional gates to suppress. Larger multiplexers are common and, as stated above, require ⌈ log 2 ⁡ ⌉ selector pins for n inputs. Other common sizes are 4-to-1, 8-to-1, 16-to-1. Since digital logic uses binary values, powers of 2 are used to maximally control a number of inputs for the given number of selector inputs; the boolean equation for a 4-to-1 multiplexer is: Z = ( A ∧ ¬ S

2 Coelhos

2 Coelhos is a 2012 Brazilian action film written and directed by Afonso Poyart. The film features innovations that were not common in Brazilian films, including explosions, elaborate special effects and pop culture references, it was released in Brazil on January 20, 2012. Edgar is arrested for killing a woman and child in a car crash, but is bailed out by state representative Jader Kerleis. After two years on vacation in Miami, Edgar returns to the city of São Paulo with a plot to pit Jader, infamous for multiple corruption cases, against Maicon, a criminal notorious for bribing influential politicians to keep him free, to bring both of them to justice. Radiohead - "Exit Music" Matanza - "Imbecil" Tom Waits - "I'm still here" Titãs - "Será que é isso que necessito?" Thirty Seconds to Mars - "Kings and Queens" Lenine - "Paciência" Tango Pictures bought the rights to remake this film with a title Two Rabbits. The film will be the second project for the development of new production, directed by Andrew Lazar, Christina Lurie and Steven Shainberg.

Afonso Poyart says. Poyart said, "The idea is to make another movie. At the moment, the Tango is hiring writers that will give a new treatment history and acclimation to the American public"; the budget of the film should cost between 12 million. Official website 2 Coelhos on IMDb

North American Pairs

The North American Pairs is a set of annual North American championships for pairs contested over two days at the spring American Contract Bridge League North American Bridge Championships. The events are restricted to pairs that have qualified through local and district levels within their ACBL Districts. Three fields or "Flights" compete on the same schedule: Flight A, open to all players, is formally the Baldwin North American Pairs. Flight B, restricted to players with 0 to 2500 masterpoints, is formally the Golder North American Pairs. Flight C, restricted to players who have not yet become Life Masters and have fewer than 500 masterpoints, is formally the President's Cup North American Pairs; each competition is a four-session matchpoint pairs tournament with two qualifying sessions on the first day and two final sessions on the second. Play for the Baldwin North American Pairs begins each summer at the local level and concludes at the North American Bridge Championships in the following Spring.

Qualifiers at the club level advance to unit competition and those qualifiers advance to district finals. Three pairs from each district – more, depending upon attendance – qualify for the North American final. At inauguration, the open pairs contest was named the Grand National Pairs with 61,000 starting pairs participating in the initial local stage in August 1978 - the ultimate winners arising from the 1979 Spring NABC; the contest was renamed the North American Pairs in deference to the participation of all country members of the ACBL. Winners have their names inscribed on the Baldwin Trophy and receive certificates of recognition; the trophy is presented in memory of Col. Russell J. Baldwin, a U. S. Army officer and expert on tournament procedure, ACBL Honorary Member of the Year in 1943. Baldwin was active as an organizer from the earliest days of contract bridge, he became a director of the American Bridge League and its treasurer shortly after its founding in 1927. He was a member of the ACBL Laws Commission and was responsible for the first Duplicate Code issued in 1935.

Baldwin was active as a tournament director from 1927 until 1941. After service in World War II, he was ACBL business manager from 1946 until 1951, he was recalled to military service at the outbreak of the Korean War and retired from the U. S. Army in 1957, he rejoined ACBL in 1958 and was in charge of tournament scheduling until his retirement in 1963. Known as the Golder North American Pairs - Flight B, the first stage of the event is conducted at the local club level with qualifiers advancing to unit competition; those qualifiers advance to the district finals where three pairs – more, depending upon attendance – qualify for the North American final. The inaugural event was held at the 1992 Spring NABC. Winners have their names inscribed on the Golder Cup and will receive a certificate of recognition; the trophy is presented in memory of Benjamin M. Golder of Philadelphia, who died the day before the close of his term as 1946 ACBL president, he was named ACBL Honorary Member of the Year for 1947.

His widow Peggy Golder Solomon, was an ACBL Hall of Fame player. Players in the North American Pairs - Flight C, compete for the President's Cup; the inaugural event was held at the 1987 Spring NABC. The trophy was presented in 1942 by ACBL president that year. For many years it was awarded to the winners of the President's Pairs, a standalone event at the Summer NABC; as in the other two flights, Flight C competition begins each summer at the local club level and qualifiers advance to unit and district competitions with three pairs from each district – more, depending upon attendance – qualifying for the North American final.

Danny Polo

Danny Polo was an American jazz clarinetist. Polo's father was a clarinetist, he learned to play from a young age, working in marching bands from age eight. Claude Thornhill played with Polo as a duo in his youth. In the 1920s, Polo played with Elmer Schoebel, Merritt Brunies, Arnold Johnson, Ben Bernie, Jean Goldkette, Paul Ash. In 1927 he went with Dave Tough to Europe, where he played with several Continental bandleaders including Bert Firman, Lud Gluskin, George Carhart, Ben Berlin and Arthur Briggs. From 1930-1935 Polo played with Ambrose returned to the U. S. in December of that year. In 1938, Polo returned to Britain to play with Ambrose again, worked with Ray Ventura in Paris in 1939. Late in 1939 he moved back to the U. S. for good, spent the early 1940s working with Joe Sullivan, Jack Teagarden, Claude Thornhill again. He led his own Midwestern territory band for a time returned to play with Thornhill once more in 1947. While with Thornhill he became ill, died rather in 1949, his gravestone gives his correct name as Pollo.

He recorded two sessions as a leader, both in Europe, in 1938-39. It is known that Polo played in several experimental sessions with Miles Davis around 1947-48 Scott Yanow, Danny Polo at Allmusic

Konstantin Arsenović

Konstantin Arsenović was a politician and military official in Serbia. He served in the National Assembly of Serbia from 2008 until his death in 2017. Arsenović was a member of the Party of United Pensioners of Serbia and a deputy speaker of the assembly. Arsenović was born in 1940 in the village of Gornje Košlje in the Ljubovija municipality, at the time part of the Drina Banovina in the Kingdom of Yugoslavia but and subsequently a part of Serbia, his parliamentary biography indicates that, after attending technical high school, he attended Yugoslavia's Military Technical Academy, High Military Technical Academy and Staff School, National Defence School. He served in the Yugoslav National Army and the successor Armed Forces of Yugoslavia from 1961 to 2000, overseeing a variety of responsibilities. On September 5, 1996, Arsenović was appointed by Yugoslav president Zoran Lilić as assistant head of the Yugoslav Army General Staff responsible for reinforcements. On December 25, 1998, he was appointed as an advisor to Yugoslav minister of defense Pavle Bulatović.

He retired in 2000 with the rank of lieutenant colonel general. Arsenović was a founding member of the Party of United Pensioners of Serbia in 2005; this party contested the 2007 Serbian parliamentary election in an alliance with the Social Democratic Party, Arsenović received the seventh position on their combined electoral list. The list did not cross the electoral threshold to win representation in the assembly; the United Pensioners joined an electoral alliance led by the Socialist Party of Serbia for the 2008 parliamentary election. Arsenović was given the seventh position on the alliance's list and entered the assembly as part of the PUPS delegation after the alliance won twenty mandates; the United Pensioners were included in Mirko Cvetković's administration, Arsenović served as a parliamentary supporter of the government. Serbia's electoral system was reformed in 2011, such that parliamentary mandates were awarded in numerical order to candidates on successful lists; the United Pensioners' alliance with the Socialist Party continued into the 2014 elections.

PUPS remained part of the government from 2012 to 2014 and provided external support to Aleksandar Vučić's administration from 2014 to 2016. Arsenović was named as a deputy speaker of the assembly following the 2012 election, a position that he retained for all sittings of the assembly until his death. In 2011, Arsenović offered support to an idea proposed by the Serbian Progressive Party that Serbia reinstate a conscript army, he argued that Serbia did not have an army capable of carrying out the fundamental tasks required of it and offered his view that conscription should never have been abolished. He further argued that most people in Serbia held the same belief and would willingly send their children to military service. For the 2016 Serbian parliamentary election, the United Pensioners joined the Aleksandar Vučić – Serbia Is Winning electoral alliance led by the Progressive Party. Arsenović received the sixty-first position on their list and was declared re-elected when the list a won a landslide victory with 131 out of 250 mandates.

PUPS returned to direct participation in government after the election. In this sitting of the assembly, Arsenović was a member of the committee of the rights of the child and a member of the friendship groups for Belarus and Spain. Arsenović died on January 31, 2017, aged seventy-six
