  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...

By the principal terms of the Treaty of Tilsit, Russiagave...

• One Hundred Years of Olympics.

  Getting over the Hurdles The next three Olympics attracted more athletes and saw stronger performances but otherwise did not measure up to Athens. The 1900 Paris Olympics were upstagedby the concurrent Exposition Universelle and were spread out over two months. The 1904 games in remote St. Louis were subordinated to the Louisiana PurchaseExhibition; over three-fourths of the competitors were Americans, and even Coubertin did not attend. The 1908 London Olympics were also overshadowed byanother...

• OEUVRE POUR L'ORAL : PROPOSITIONS 1 à 6 - Kant : Idée d'une histoire universelle au point de vue cosmopolitique

  INTRODUCTION I) La problématique de l’histoire - Le mot histoire est dérivé d’un mot grec qui signifiait enquête. Ce mot possède deux significations principales. Il y a d’une part l’histoire qui est écrite par les historiens; son but est la connaissance du passé des sociétés humaines ou, comme l’écrit Raymond Aron, “ la science que les hommes s’efforcent d’élaborer de leur devenir ”. Il y a d’autre part l’histoire comme succession...

  Thème 5: l’environnement entre exploitations et protection . Chap 1: qu’est ce que l’environnement ? Introduction : l’environnement est une notion qui a évolué depuis le 19e siècle. Dans un premier temps elle signifiait milieux en d’autre terme les endroits autour de l’Homme. Aujourd’hui l’environnement est l’ensemble des relations entre les sociétés et les milieux à différentes échelles d’espaces et de temps. C’est donc littéralement “ce qui entoure” c’est à dire l’ensemble des éléments...

• Arab Music I INTRODUCTION Umm Kulthum Egyptian singer Umm Kulthum was revered throughout Egypt, North Africa, and the Near East for her powerful voice and improvisational skill.

  The rhythmic structure of Arab music is similarly complex. Rhythmic patterns have up to 48 beats and typically include several downbeats (called dums ) as well as upbeats (called taks) and silences, or rests. To grasp a rhythmic mode, the listener must hear a relatively long pattern. Moreover, the performers do not simply play the pattern; they elaborate upon and ornament it. Often the pattern is recognizable by the arrangement of downbeats. The Rhythm in Arab Music illustration demonstratesa...

• Suicide.

  C Sociological Theories Most social scientists believe that a society’s structure and values can influence suicide rates. French sociologist Émile Durkheim argued that suicide rates are related tosocial integration —that is, the degree to which an individual feels part of a larger group. Durkheim found suicide was more likely when a person lacked social bonds or had relationships disrupted through a sudden change in status, such as unemployment. As one example of the significance of social bond...

  from a flower with several pistils. The ovary may have a single compartment, or carpel, which houses the ovule or ovules. Or the ovary may consist of two or morecarpels, each of which may contain one or more ovules. A drupe develops from an ovary with a single carpel and is characterized by an edible exocarp and mesocarp and an inedible, hard endocarp, or pit that encloses asingle seed. Cherries, peaches, apricots, and plums are examples of drupes. Almonds also are classified as drupes, but in a...

• Millennium.

  Postmillennialism, also referred to as progressive millennialism, interprets the Bible less literally than premillennialism does. Postmillennialists regard the millennium as a1,000-year reign of Christian ideals that will end with the return of Christ. In this view, the millennium will not start suddenly through an apocalypse, but graduallythrough the efforts of human beings. Postmillennialists believe that through social reform and by upholding Christian ideals, the kingdom of God will be built...

  days and disappear in seven to ten days. However, coughing and fatigue may persist for two or more weeks. Death from influenza itself is rare. But influenza can aggravate underlying medical conditions, such as heart or lung disease. Invading influenza viruses produceinflammation in the lining of the respiratory tract, damage that increases the risk that secondary infections will develop. Common complications include bronchitis,sinusitis, and bacterial pneumonia, occurring most frequently in olde...

• Astronaut - astronomy.

  Every operation during a flight is important and interesting, but many might be boring to an observer. Much of an astronaut’s job is entering computer instructions,preparing samples, making measurements, recording data, fixing what breaks, and adjusting the checklist when something unexpected happens. Sometimes astronautsretrieve or repair satellites, rendezvous or dock with other spacecraft, and do important emergency repairs. The adaptability of the human crew is crucial to the successof missi...

• Capitalism.

  Physiocracy is the term applied to a school of economic thought that suggested the existence of a natural order in economics, one that does not require direction from the state for people to be prosperous. The leader of the physiocrats, the economist François Quesnay, set forth the basic principles in his Tableau économique (1758), in which he traced the flow of money and goods through the economy. Simply put, this flow was seen to be both circular and self-sustaining. More important, however...

• Horse Racing.

  interested parties claim the same horse at the same price, lots are drawn to determine the winning offer. Knowledgeable owners and trainers may use claiming races toobtain, at bargain prices, horses whose former owners underestimated the potential of their animals. Two other types of contests are match races and walkovers. A match race pits only two horses, almost always that season’s most successful racers, in a head-to-headduel. A walkover occurs when only one horse has not been scratched (w...

• Virus (life science) - biology.

  RNA into DNA earned them their name because this process is the reverse of the usual transfer of genetic information, from DNA to RNA.) The DNA form of theretrovirus genome is then integrated into the cellular DNA and is referred to as the provirus. The viral genome is replicated every time the host cell replicates its DNA and is thus passed on to daughter cells. Hepatitis B virus can also transcribe RNA to DNA, but this virus packages the DNA version of its genome into virus particles. Unlike...

  allele from the mother and a mutated allele from the father. In both of these cases, the child will be a carrier. The child develops the disease only if he or she receives amutated allele from each parent. When both parents are carriers, there is a 25 percent chance that a child will be disease-free, a 25 percent chance that it will have thedisease, and a 50 percent chance that it will be a carrier. Examples of genetic diseases that follow the dominant-recessive pattern include sickle-cell anemi...

• Supernova - astronomy.

  The term hypernova has been proposed for an extremely massive core-collapse supernova—possibly more than 100 times the mass of the Sun. A hypernova is thought to form a black hole. Just before it explodes, a hypernova may release a huge burst of gamma rays in a jet from the rotating black hole at its center. These jets mayexplain the so-called long gamma-ray bursts detected by astronomers. According to some researchers, massive stars with over 40 solar masses may sometimescollapse directly int...

• Tree - biology.

  The major parts of a tree are its roots, trunk, leaves, flowers, and seeds. These components play vital roles in a tree’s growth, development, and reproduction. A Roots Trees are held in place by anchoring organs called roots. In addition to anchoring the tree, roots also absorb water and minerals through tiny structures called roothairs. From the roots the water and mineral nutrients are carried upward through the wood cells to the leaves. Although the internal structure of most kinds of roots...
