  Sustainability 2019,11 , 189 2 of 24Since the 1980s, many research was conducted to minimize the error of prediction through a method dubbed as gradient descent. This method is referred to as a Backpropagation algorithm for the training of the ANNs and it was applied to solve problems in different domains using few hidden layers [ 5,6]. Today, the availability of data has introduced the concept of machine learning as a subcategory to AI. Machine learning implies coding the computers to behave l...

• Slavery in Africa.

  The spread of Islam from Arabia into Africa after the religion’s founding in the 7th century AD affected the practice of slavery and slave trading in West, Central, and East Africa. Arabs had practiced slave raiding and trading in Arabia for centuries prior to the founding of Islam, and slavery became a component of Islamic traditions.Both the Qur'an (Koran) (the sacred scripture of Islam) and Islamic religious law served to codify and justify the existence of slavery. As Muslim Arabs conquered...

• Rhinoceros - biology.

  Male and female rhinos have a similar physical appearance, although male rhinos are usually larger than females, with the size difference varying between species. Inthe wild, some rhinos probably live into their late 40s, and they have survived into their 30s in captivity. IV TYPES OF RHINOCEROSES Until recently, mammalogists divided the rhinoceros family into three subfamilies, each with different characteristics. Scientists now believe that living rhinos belong to asingle subfamily, although...

• Venus (planet) - astronomy.

  level winds circle the planet at 360 km/h (225 mph), making a complete rotation in only four days. These winds are said to super-rotate because they travel muchfaster than the rotation of the planet itself. These high-speed winds cover the planet completely, blowing toward the west at virtually every latitude from equator topole. The motions of descending probes, however, have shown that the bulk of Venus’s tremendously dense atmosphere, closer to the planet’s surface, is almoststagnant. From th...

  Observatory). In some telescopes designed in the 1990s, the mirror’s weight has been dramatically reduced by sandwiching a honeycomb pattern of glass ribs between a thin, butrigid, concave mirror and a flat back plate. Engineers have even developed meniscus mirrors—mirrors that are too thin to support their own weight. An adjustableframework supports the meniscus mirror, and servomechanical actuators, controlled by computer, continually adjust the shape of the mirror as it tracks celestial tar...

  in their heads that conduct sound. They are able to hear low-frequency sounds and to sense vibrations that travel through the ground or water. The majority of snakeshave good eyesight, especially for detecting moving objects, although most burrowing snakes can only distinguish between light and dark. Pit vipers, boas, and pythons have an unusual adaptation for detecting warm-blooded prey and predators. On the heads of these snakes are small pits lined with cellsthat are extremely sensitive to he...

  Saxony, he made war against the Schmalkaldic League, a defensive association of Protestant princes. The Roman Catholic forces were successful at first. Later,however, Duke Maurice went over to the Protestant side, and Charles V was obliged to make peace. The religious civil war ended with the religious Peace of Augsburg in1555. Its terms provided that each of the rulers of the German states, which numbered about 300, choose between Roman Catholicism and Lutheranism and enforcethe chosen faith up...

• Dolphin (aquatic mammal) - biology.

  Scientists have observed dolphins displaying three types of caregiving behaviors: standing by, excitement, and supporting. In standing-by behavior, dolphins remain inthe vicinity of an injured or ill companion without offering aid. In excitement behavior, dolphins swim swiftly in circles around an injured dolphin, responding aggressivelytoward threats to the injured animal. For instance, they may bite harpoon lines or charge boats that come too close to the animal. In supporting behavior, one or...

• Slavery in the United States - U.

  tripled, from about 1.2 million to almost 4 million in 1860. The natural growth of the slave population meant that slavery could survive without new slave imports. Natural population growth also hastened the transition from an African to an African American slave population. By the 1770s, only about 20 percent of slaves in thecolonies were African-born, although the concentration of Africans remained higher in South Carolina and Georgia. After 1808 the proportion of African-born slavesbecame tin...

  were usually natural caves. Eventually people learned to dip branches in pitch to form torches. They created crude lamps by filling a hollowed out piece of stone withmoss soaked in oil or tallow (a substance derived from animal fat). By cooking with fire, prehistoric people made the meat of the animals they killed more palatable and digestible. They learned to preserve meat by smoking it over a fire,vastly decreasing the danger of periodic starvation. Cooking also enabled them to add some for...

They believed that the working class—with its struggles to organize trade unions and to bring about political reforms of benefit to the majority ofpeople—would become the primary force for revolutionary change. The Russian Marxists formed the Russian Social Democratic Labor Party (RSDLP) in 1898. By 1903,however, the RSDLP had split into two factions. The faction called the Bolsheviks (from the Russian word for “majority”), led by Vladimir Ilich Lenin, favored a more centralized a...

• Bosnia and Herzegovina - country.

  Serb military campaigns in 1992 and 1993 and Croat campaigns in 1993 and 1995 were aimed at expelling others from areas claimed by these groups. By the end ofthe war almost all non-Serbs had been expelled from Serb-claimed lands in eastern and northern Bosnia, and non-Croats from Croat-claimed lands in southwesternBosnia. In turn, most non-Muslims had left land under Muslim control in northwestern Bosnia. The largest cities had mixed populations in 1991, but the war and its aftermath made them a...

  When they arrived in America, African slaves were washed, and their skin was cover by animal fat or oil to look healthier. Moreover, sometimes they were branded to be recognizing as a slave. Then, they were sold in slave’s auction or market. When a slave’s auction would happen in the town, posters were published in order to advertising slave owners. It existed two different slave auctions: the first, called the “May the highest bidder wins” was to give the higher amount of money for...

• Meteor Shower - astronomy.

  Meteor observations with radar work much the same way that observations with radio forward scattering observations do. With radar, the receiver and transmitter areat the same place. Both methods provide numbers of meteors per hour, without the visual observer’s dependence on a clear, dark sky. Astronomers can determine the orbit of the particle stream that creates a meteor shower by finding out the radiant of the shower and the speed of the meteors.Observers must record meteors with cameras or v...

• Neutron Star - astronomy.

  about three times the full mass of the sun, the gravitational force will exceed the strength of the material, and the core will collapse until it disappears from the visibleuniverse altogether. This extreme state of gravitational collapse is known as a black hole. Astronomers speculate that neutron stars in interacting binary star systemscan become black holes by accumulating mass in the same way that white dwarf stars in interacting binary star systems become more massive.

• Giraffe - biology.

  One of the most striking elements of giraffe behavior is the duel between males fighting for mating privileges. Giraffe duels are among the most extraordinary in theanimal kingdom. They start when two males approach each other and begin to rub and intertwine their necks. This behavior—known as necking—allows the opponentsto assess each other’s size and strength. Often, necking alone is enough to establish seniority. If not, the rivals begin to exchange blows with their heads. Each giraffebraces...
