However, performance enhancements cannot be generalized as the benefits and limitations of the system are dependent on many factors. One problem is that the system is subject to gaming. Sometimes, one person enters the destination for a large group of people going to the same floor. The dispatching algorithm is usually unable to completely cater for the variation, and latecomers may find the elevator they are assigned to is already full. Also, occasionally, one person may press the floor multiple times. This is common with up/down buttons when people believe this to be an effective way to hurry elevators. However, this will make the computer think multiple people are waiting and will allocate empty cars to serve this one person.

The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychaetes. Annelids are considered members of the Lophotrochozoa, a "super-phylum" of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans.

Question: Which subtype of annelids includes most marine worms?
Answer: polychaetes.

Back in Warsaw that year, Chopin heard Niccolò Paganini play the violin, and composed a set of variations, Souvenir de Paganini. It may have been this experience which encouraged him to commence writing his first Études, (1829–32), exploring the capacities of his own instrument. On 11 August, three weeks after completing his studies at the Warsaw Conservatory, he made his debut in Vienna. He gave two piano concerts and received many favourable reviews—in addition to some commenting (in Chopin's own words) that he was "too delicate for those accustomed to the piano-bashing of local artists". In one of these concerts, he premiered his Variations on Là ci darem la mano, Op. 2 (variations on an aria from Mozart's opera Don Giovanni) for piano and orchestra. He returned to Warsaw in September 1829, where he premiered his Piano Concerto No. 2 in F minor, Op. 21 on 17 March 1830.

Luftwaffe policy at this point was primarily to continue progressive attacks on London, chiefly by night attack; second, to interfere with production in the vast industrial arms factories of the West Midlands, again chiefly by night attack; and third to disrupt plants and factories during the day by means of fighter-bombers. Kesselring, commanding Luftflotte 2, was ordered to send 50 sorties per night against London and attack eastern harbours in daylight. Sperrle, commanding Luftflotte 3, was ordered to dispatch 250 sorties per night including 100 against the West Midlands. Seeschlange would be carried out by Fliegerkorps X (10th Air Corps) which concentrated on mining operations against shipping. It also took part in the bombing over Britain. By 19/20 April 1941, it had dropped 3,984 mines, ⅓ of the total dropped. The mines' ability to destroy entire streets earned them respect in Britain, but several fell unexploded into British hands allowing counter-measures to be developed which damaged the German anti-shipping campaign.

The pricing of risk refers to the incremental compensation required by investors for taking on additional risk, which may be measured by interest rates or fees. Several scholars have argued that a lack of transparency about banks' risk exposures prevented markets from correctly pricing risk before the crisis, enabled the mortgage market to grow larger than it otherwise would have, and made the financial crisis far more disruptive than it would have been if risk levels had been disclosed in a straightforward, readily understandable format.

Question: What is the incremental compensation required by investors for taking on addition risk called?
Answer: pricing of risk.

Although the ECB is governed by European law directly and thus not by corporate law applying to private law companies, its set-up resembles that of a corporation in the sense that the ECB has shareholders and stock capital. Its capital is five billion euros which is held by the national central banks of the member states as shareholders. The initial capital allocation key was determined in 1998 on the basis of the states' population and GDP, but the key is adjustable. Shares in the ECB are not transferable and cannot be used as collateral.

In the hindgut (element 16 in numbered diagram), or proctodaeum, undigested food particles are joined by uric acid to form fecal pellets. The rectum absorbs 90% of the water in these fecal pellets, and the dry pellet is then eliminated through the anus (element 17), completing the process of digestion. The uric acid is formed using hemolymph waste products diffused from the Malpighian tubules (element 20). It is then emptied directly into the alimentary canal, at the junction between the midgut and hindgut. The number of Malpighian tubules possessed by a given insect varies between species, ranging from only two tubules in some insects to over 100 tubules in others.:71–72, 78–80

The prolonged Byzantine-Sassanid Wars, most importantly the climactic Byzantine-Sassanid War of 602-628, as well as the social conflict within the Sassanid Empire, opened the way for an Arab invasion to Iran in the 7th century. Initially defeated by the Arab Rashidun Caliphate, Iran came under the rule of the Arab caliphates of Umayyad and Abbasid. The prolonged and gradual process of the Islamization of Iran began following the conquest. Under the new Arab elite of the Rashidun and later the Umayyad caliphates, both converted (mawali) and non-converted (dhimmi) Iranians were discriminated against, being excluded from the government and military, and having to pay a special tax called Jizya. Gunde Shapur, home of the Academy of Gunde Shapur which was the most important medical center of the world at the time, survived after the invasion, but became known as an Islamic institute thereafter.

The territory that now constitutes Tajikistan was previously home to several ancient cultures, including the city of Sarazm of the Neolithic and the Bronze Age, and was later home to kingdoms ruled by people of different faiths and cultures, including the Oxus civilization, Andronovo culture, Buddhism, Nestorian Christianity, Zoroastrianism, and Manichaeism. The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sassanian Empire, Hephthalite Empire, Samanid Empire, Mongol Empire, Timurid dynasty, and the Russian Empire. As a result of the breakup of the Soviet Union, Tajikistan became an independent nation in 1991. A civil war was fought almost immediately after independence, lasting from 1992 to 1997. Since the end of the war, newly established political stability and foreign aid have allowed the country's economy to grow.

These immigrants were largely responsible for the first general strike in North America in 1835, in which workers in the city won the ten-hour workday. The city was a destination for thousands of Irish immigrants fleeing the Great Famine in the 1840s; housing for them was developed south of South Street, and was later occupied by succeeding immigrants. They established a network of Catholic churches and schools, and dominated the Catholic clergy for decades. Anti-Irish, anti-Catholic Nativist riots had erupted in Philadelphia in 1844. In the latter half of the century, immigrants from Russia, Eastern Europe and Italy; and African Americans from the southern U.S. settled in the city. Between 1880 and 1930, the African-American population of Philadelphia increased from 31,699 to 219,559. Twentieth-century black newcomers were part of the Great Migration out of the rural South to northern and midwestern industrial cities.

Early in 1953, the French asked Eisenhower for help in French Indochina against the Communists, supplied from China, who were fighting the First Indochina War. Eisenhower sent Lt. General John W. "Iron Mike" O'Daniel to Vietnam to study and assess the French forces there. Chief of Staff Matthew Ridgway dissuaded the President from intervening by presenting a comprehensive estimate of the massive military deployment that would be necessary. Eisenhower stated prophetically that "this war would absorb our troops by divisions."

Hayek's work on the microeconomics of the choice theoretics of investment, non-permanent goods, potential permanent resources, and economically-adapted permanent resources mark a central dividing point between his work in areas of macroeconomics and that of almost all other economists. Hayek's work on the macroeconomic subjects of central planning, trade cycle theory, the division of knowledge, and entrepreneurial adaptation especially, differ greatly from the opinions of macroeconomic "Marshallian" economists in the tradition of John Maynard Keynes and the microeconomic "Walrasian" economists in the tradition of Abba Lerner.

Poultry meat and eggs provide nutritionally beneficial food containing protein of high quality. This is accompanied by low levels of fat which have a favourable mix of fatty acids. Chicken meat contains about two to three times as much polyunsaturated fat as most types of red meat when measured by weight. However, for boneless, skinless chicken breast, the amount is much lower. A 100-g serving of baked chicken breast contains 4 g of fat and 31 g of protein, compared to 10 g of fat and 27 g of protein for the same portion of broiled, lean skirt steak.

From the 1930s through much of the 1960s, Florida was essentially a one-party state dominated by white conservative Democrats, who together with other Democrats of the Solid South, exercised considerable control in Congress. They gained federal money from national programs; like other southern states, Florida residents have received more federal monies than they pay in taxes: the state is a net beneficiary. Since the 1970s, the conservative white majority of voters in the state has largely shifted from the Democratic to the Republican Party. It has continued to support Republican presidential candidates through the 20th century, except in 1976 and 1996, when the Democratic nominee was from the South. They have had "the luxury of voting for presidential candidates who pledge to cut taxes and halt the expansion of government while knowing that their congressional delegations will continue to protect federal spending."

While Blacks/African-Americans comprised only 13 percent of Michigan's population in 2010, they made up nearly 82 percent of Detroit's population. The next largest population groups were Whites, at 10 percent, and Hispanics, at 6 percent. According to the 2010 Census, segregation in Detroit has decreased in absolute and in relative terms. In the first decade of the 21st century, about two-thirds of the total black population in metropolitan area resided within the city limits of Detroit. The number of integrated neighborhoods has increased from 100 in 2000 to 204 in 2010. The city has also moved down the ranking, from number one most segregated to number four. A 2011 op-ed in The New York Times attributed the decreased segregation rating to the overall exodus from the city, cautioning that these areas may soon become more segregated. This pattern already happened in the 1970s, when apparent integration was actually a precursor to white flight and resegregation. Over a 60-year period, white flight occurred in the city. According to an estimate of the Michigan Metropolitan Information Center, from 2008 to 2009 the percentage of non-Hispanic White residents increased from 8.4% to 13.3%. Some empty nesters and many younger White people moved into the city while many African Americans moved to the suburbs.

Government revenues largely come from sales of fishing licenses, income from the Tuvalu Trust Fund, and from the lease of its highly fortuitous .tv Internet Top Level Domain (TLD). In 1998, Tuvalu began deriving revenue from the use of its area code for premium-rate telephone numbers and from the commercialisation of its ".tv" Internet domain name, which is now managed by Verisign until 2021. The ".tv" domain name generates around $2.2 million each year from royalties, which is about ten per cent of the government's total revenue. Domain name income paid most of the cost of paving the streets of Funafuti and installing street lighting in mid-2002. Tuvalu also generates income from stamps by the Tuvalu Philatelic Bureau and income from the Tuvalu Ship Registry.

The immediate predecessors of MP3 were "Optimum Coding in the Frequency Domain" (OCF), and Perceptual Transform Coding (PXFM). These two codecs, along with block-switching contributions from Thomson-Brandt, were merged into a codec called ASPEC, which was submitted to MPEG, and which won the quality competition, but that was mistakenly rejected as too complex to implement. The first practical implementation of an audio perceptual coder (OCF) in hardware (Krasner's hardware was too cumbersome and slow for practical use), was an implementation of a psychoacoustic transform coder based on Motorola 56000 DSP chips.
