An academic conference or scientific conference is a event for researchers to present and discuss their work. Together with academic or scientific journals, conferences provide an important channel for exchange of information between researchers. Conferences encompass various presentations, they tend to be concise, with a time span of about 10 to 30 minutes. The work may be bundled in written form as academic papers and published as the conference proceedings. A conference will include keynote speakers; the keynote lecture is longer, lasting sometimes up to an hour and a half if there are several keynote speakers on a panel. In addition to presentations, conferences feature panel discussions, round tables on various issues, poster sessions and workshops; some conferences take more interactive formats, such as the participant driven "unconference" or various conversational formats. Some academic conferences include the Artificial Intelligence International Conference, TED, Festival of Marketing, AliensFest.
Prospective presenters are asked to submit a short abstract of their presentation, which will be reviewed before the presentation is accepted for the meeting. Some disciplines require presenters to submit a paper of about 6–15 pages, peer reviewed by members of the program committee or referees chosen by them. In some disciplines, such as English and other languages, it is common for presenters to read from a prepared script. In other disciplines such as the sciences, presenters base their talk around a visual presentation that displays key figures and research results. A large meeting will be called a conference, while a smaller is termed a workshop, they might be single track or multiple track, where the former has only one session at a time, while a multiple track meeting has several parallel sessions with speakers in separate rooms speaking at the same time. The larger the conference, the more it is that academic publishing houses may set up displays. Large conferences may have a career and job search and interview activities.
At some conferences, social or entertainment activities such as tours and receptions can be part of the program. Business meetings for learned societies or interest groups can be part of the conference activities. Academic conferences fall into three categories: the themed conference, small conferences organized around a particular topic; these conferences are organized by regional, national, or international learned societies, held annually or on some other regular basis. The professional conference, large conferences not limited to academics but with academically related issues. Increasing numbers of amplified conferences are being provided which exploit the potential of WiFi networks and mobile devices in order to enable remote participants to contribute to discussions and listen to ideas. Advanced technology for meeting with any yet unknown person in a conference is performed by active RFID that may indicate wilfully identified and located upon approach via electronic tags. Conferences are organized either by a scientific society or by a group of researchers with a common interest.
Larger meetings may be handled on behalf of the scientific society by a Professional Conference Organiser or PCO. The meeting is announced by way of a Call For Papers or a Call For Abstracts, sent to prospective presenters and explains how to submit their abstracts or papers, it describes the broad theme and lists the meeting's topics and formalities such as what kind of abstract or paper has to be submitted, to whom, by what deadline. A CFP is distributed using a mailing list or on specialized online services. Contributions are submitted using an online abstract or paper management service. There has been a call for more sustainable academic conferencing, as flying to and consumption at conferences is one of the largest components of an academics environmental footprint. However, few conferences have enacted practices to reduce their environmental impact, despite guidelines being available. An analysis of academic conferences taking place in 2016, showed that only 4% of 116 conferences sampled offered carbon offset options and only 9% of these conferences implemented any form of action to their reduce environmental impact.
There have been accusations for scam, or fraudulent conferences.
Computer science is the study of processes that interact with data and that can be represented as data in the form of programs. It enables the use of algorithms to manipulate and communicate digital information. A computer scientist studies the theory of computation and the practice of designing software systems, its fields can be divided into practical disciplines. Computational complexity theory is abstract, while computer graphics emphasizes real-world applications. Programming language theory considers approaches to the description of computational processes, while computer programming itself involves the use of programming languages and complex systems. Human–computer interaction considers the challenges in making computers useful and accessible; the earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks such as the abacus have existed since antiquity, aiding in computations such as multiplication and division.
Algorithms for performing computations have existed since antiquity before the development of sophisticated computing equipment. Wilhelm Schickard designed and constructed the first working mechanical calculator in 1623. In 1673, Gottfried Leibniz demonstrated a digital mechanical calculator, called the Stepped Reckoner, he may be considered the first computer scientist and information theorist, among other reasons, documenting the binary number system. In 1820, Thomas de Colmar launched the mechanical calculator industry when he released his simplified arithmometer, the first calculating machine strong enough and reliable enough to be used daily in an office environment. Charles Babbage started the design of the first automatic mechanical calculator, his Difference Engine, in 1822, which gave him the idea of the first programmable mechanical calculator, his Analytical Engine, he started developing this machine in 1834, "in less than two years, he had sketched out many of the salient features of the modern computer".
"A crucial step was the adoption of a punched card system derived from the Jacquard loom" making it infinitely programmable. In 1843, during the translation of a French article on the Analytical Engine, Ada Lovelace wrote, in one of the many notes she included, an algorithm to compute the Bernoulli numbers, considered to be the first computer program. Around 1885, Herman Hollerith invented the tabulator, which used punched cards to process statistical information. In 1937, one hundred years after Babbage's impossible dream, Howard Aiken convinced IBM, making all kinds of punched card equipment and was in the calculator business to develop his giant programmable calculator, the ASCC/Harvard Mark I, based on Babbage's Analytical Engine, which itself used cards and a central computing unit; when the machine was finished, some hailed it as "Babbage's dream come true". During the 1940s, as new and more powerful computing machines were developed, the term computer came to refer to the machines rather than their human predecessors.
As it became clear that computers could be used for more than just mathematical calculations, the field of computer science broadened to study computation in general. In 1945, IBM founded the Watson Scientific Computing Laboratory at Columbia University in New York City; the renovated fraternity house on Manhattan's West Side was IBM's first laboratory devoted to pure science. The lab is the forerunner of IBM's Research Division, which today operates research facilities around the world; the close relationship between IBM and the university was instrumental in the emergence of a new scientific discipline, with Columbia offering one of the first academic-credit courses in computer science in 1946. Computer science began to be established as a distinct academic discipline in the 1950s and early 1960s; the world's first computer science degree program, the Cambridge Diploma in Computer Science, began at the University of Cambridge Computer Laboratory in 1953. The first computer science degree program in the United States was formed at Purdue University in 1962.
Since practical computers became available, many applications of computing have become distinct areas of study in their own rights. Although many believed it was impossible that computers themselves could be a scientific field of study, in the late fifties it became accepted among the greater academic population, it is the now well-known IBM brand that formed part of the computer science revolution during this time. IBM released the IBM 704 and the IBM 709 computers, which were used during the exploration period of such devices. "Still, working with the IBM was frustrating if you had misplaced as much as one letter in one instruction, the program would crash, you would have to start the whole process over again". During the late 1950s, the computer science discipline was much in its developmental stages, such issues were commonplace. Time has seen significant improvements in the effectiveness of computing technology. Modern society has seen a significant shift in the users of computer technology, from usage only by experts and professionals, to a near-ubiquitous user base.
Computers were quite costly, some degree of humanitarian aid was needed for efficient use—in part from professional computer operators. As computer adoption became more widespread and affordable, less human assistance was needed for common usage. Despite its short history as a formal academic discipline, computer science has made a number of fundamental contributions to science and society—in fact, along with electronics, it is
France the French Republic, is a country whose territory consists of metropolitan France in Western Europe and several overseas regions and territories. The metropolitan area of France extends from the Mediterranean Sea to the English Channel and the North Sea, from the Rhine to the Atlantic Ocean, it is bordered by Belgium and Germany to the northeast and Italy to the east, Andorra and Spain to the south. The overseas territories include French Guiana in South America and several islands in the Atlantic and Indian oceans; the country's 18 integral regions span a combined area of 643,801 square kilometres and a total population of 67.3 million. France, a sovereign state, is a unitary semi-presidential republic with its capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban areas include Lyon, Toulouse, Bordeaux and Nice. During the Iron Age, what is now metropolitan France was inhabited by a Celtic people. Rome annexed the area in 51 BC, holding it until the arrival of Germanic Franks in 476, who formed the Kingdom of Francia.
The Treaty of Verdun of 843 partitioned Francia into Middle Francia and West Francia. West Francia which became the Kingdom of France in 987 emerged as a major European power in the Late Middle Ages following its victory in the Hundred Years' War. During the Renaissance, French culture flourished and a global colonial empire was established, which by the 20th century would become the second largest in the world; the 16th century was dominated by religious civil wars between Protestants. France became Europe's dominant cultural and military power in the 17th century under Louis XIV. In the late 18th century, the French Revolution overthrew the absolute monarchy, established one of modern history's earliest republics, saw the drafting of the Declaration of the Rights of Man and of the Citizen, which expresses the nation's ideals to this day. In the 19th century, Napoleon established the First French Empire, his subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a tumultuous succession of governments culminating with the establishment of the French Third Republic in 1870.
France was a major participant in World War I, from which it emerged victorious, was one of the Allies in World War II, but came under occupation by the Axis powers in 1940. Following liberation in 1944, a Fourth Republic was established and dissolved in the course of the Algerian War; the Fifth Republic, led by Charles de Gaulle, remains today. Algeria and nearly all the other colonies became independent in the 1960s and retained close economic and military connections with France. France has long been a global centre of art and philosophy, it hosts the world's fourth-largest number of UNESCO World Heritage Sites and is the leading tourist destination, receiving around 83 million foreign visitors annually. France is a developed country with the world's sixth-largest economy by nominal GDP, tenth-largest by purchasing power parity. In terms of aggregate household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, human development.
France is considered a great power in global affairs, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a leading member state of the European Union and the Eurozone, a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, La Francophonie. Applied to the whole Frankish Empire, the name "France" comes from the Latin "Francia", or "country of the Franks". Modern France is still named today "Francia" in Italian and Spanish, "Frankreich" in German and "Frankrijk" in Dutch, all of which have more or less the same historical meaning. There are various theories as to the origin of the name Frank. Following the precedents of Edward Gibbon and Jacob Grimm, the name of the Franks has been linked with the word frank in English, it has been suggested that the meaning of "free" was adopted because, after the conquest of Gaul, only Franks were free of taxation.
Another theory is that it is derived from the Proto-Germanic word frankon, which translates as javelin or lance as the throwing axe of the Franks was known as a francisca. However, it has been determined that these weapons were named because of their use by the Franks, not the other way around; the oldest traces of human life in what is now France date from 1.8 million years ago. Over the ensuing millennia, Humans were confronted by a harsh and variable climate, marked by several glacial eras. Early hominids led a nomadic hunter-gatherer life. France has a large number of decorated caves from the upper Palaeolithic era, including one of the most famous and best preserved, Lascaux. At the end of the last glacial period, the climate became milder. After strong demographic and agricultural development between the 4th and 3rd millennia, metallurgy appeared at the end of the 3rd millennium working gold and bronze, iron. France has numerous megalithic sites from the Neolithic period, including the exceptiona
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Aix-en-Provence, or Aix, is a city and commune in Southern France, about 30 km north of Marseille. A former capital of Provence, it is in the region of Provence-Alpes-Côte d'Azur, in the department of Bouches-du-Rhône, of which it is a subprefecture; the population of Aix-en-Provence numbers 143,000. Its inhabitants are called Aixois or, less Aquisextains. Aix was founded in 123 BC by the Roman consul Sextius Calvinus, who gave his name to its springs, following the destruction of the nearby Gallic oppidum at Entremont. In 102 BC its vicinity was the scene of the Battle of Aquae Sextiae, where the Romans under Gaius Marius defeated the Cimbri and Teutones, with mass suicides among the captured women, which passed into Roman legends of Germanic heroism. In the 4th century AD it became the metropolis of Narbonensis Secunda, it was occupied by the Visigoths in 477. In the succeeding century, the town was plundered by the Franks and Lombards, was occupied by the Saracens in 731 and by Charles Martel in 737.
Aix, which during the Middle Ages was the capital of Provence, did not reach its zenith until after the 12th century, under the houses of Barcelona/Aragon and Anjou, it became an artistic centre and seat of learning. Aix passed to the crown of France with the rest of Provence in 1487, in 1501 Louis XII established there the parliament of Provence, which existed until 1789. In the 17th and 18th centuries, the town was the seat of the Intendance of Provence. Current archeological excavations in the Ville des Tours, a medieval suburb of Aix, have unearthed the remains of a Roman amphitheatre. A deposit of fossil bones from the Upper Continental Miocene gave rise to a Christian dragon legend. Aix-en-Provence is situated in the south of France, in a plain overlooking the Arc river, about a mile from the right bank of the river; the city slopes from north to south and the Montagne Sainte-Victoire can be seen to the east. Aix's position in the south of France gives it a warm climate, though more extreme than Marseille due to the inland location.
It has an average January temperature of 5 °C and a July average of 23 °C. It has an average of only 91 days of rain. While it is protected from the Mistral, Aix still experiences the cooler and gusty conditions it brings. Unlike most of France which has an oceanic climate, Aix-en-Provence has a Mediterranean climate; the Cours Mirabeau is a wide thoroughfare, planted with double rows of plane trees, bordered by fine houses and decorated by fountains. It follows the line of the old city wall, divides the town into two sections; the new town extends to the west. Situated on this avenue, lined on one side with banks and on the other with cafés, is the Deux Garçons, the most famous brasserie in Aix. Built in 1792, it was frequented by the likes of Émile Zola and Ernest Hemingway; the Cathedral of the Holy Saviour is situated to the north in the medieval part of Aix. Built on the site of a former Roman forum and an adjacent basilica, it contains a mixture of all styles from the 5th to the 17th century, including a richly decorated portal in the Gothic style with doors elaborately carved in walnut.
The interior contains 16th-century tapestries, a 15th-century triptych, depicting King René and his wife on the side panels, as well as a Merovingian baptistery, its Renaissance dome supported by original Roman columns. The archbishop's palace and a Romanesque cloister adjoin the cathedral on its south side; the Archbishopric of Aix is now shared with Arles. Among its other public institutions, Aix has the second most important Appeal Court outside of Paris, located near the site of the former Palace of the Counts of Provence; the Hôtel de Ville, a building in the classical style of the middle of the 17th century, looks onto a picturesque square. It contains tapestries. At its side rises a handsome clock-tower erected in 1510. On the Place de l'Hôtel de Ville is the former Corn Exchange; this ornately decorated 18th-century building was designed by the Vallon brothers. Nearby are the remarkable thermal springs, containing lime and carbonic acid, that first drew the Romans to Aix and gave it the name Aquae Sextiae.
A spa was built in 1705 near the remains of the ancient Roman baths of Sextius. South of the Cours Mirabeau is the Quartier Mazarin; this residential district was constructed for the gentry of Aix by Archbishop Michele Mazzarino brother of Cardinal Jules Mazarin in the last half of the 17th century and contains several notable hôtels particuliers. The 13th-century church of Saint-Jean-de-Malte contains valuable pictures and a restored organ. Next to it is the Musée Granet, devoted to European sculpture. Aix is referred to as the city of a thousand fountains. Among the most notable are the 17th-century Fontaine des Quatre Dauphins in the Quartier Mazarin, designed by Jean-Claude Rambot, three of the fountains down the central Cours Mirabeau: At the top, a 19th-century fountain depicts the "good king" René holding the Muscat grapes that he introduced to Provence in the 15th century.
Seattle is a seaport city on the West Coast of the United States. It is the seat of Washington. With an estimated 730,000 residents as of 2018, Seattle is the largest city in both the state of Washington and the Pacific Northwest region of North America. According to U. S. Census data released in 2018, the Seattle metropolitan area’s population stands at 3.87 million, ranks as the 15th largest in the United States. In July 2013, it was the fastest-growing major city in the United States and remained in the Top 5 in May 2015 with an annual growth rate of 2.1%. In July 2016, Seattle was again the fastest-growing major U. S. city, with a 3.1% annual growth rate. Seattle is the northernmost large city in the United States; the city is situated on an isthmus between Puget Sound and Lake Washington, about 100 miles south of the Canada–United States border. A major gateway for trade with Asia, Seattle is the fourth-largest port in North America in terms of container handling as of 2015; the Seattle area was inhabited by Native Americans for at least 4,000 years before the first permanent European settlers.
Arthur A. Denny and his group of travelers, subsequently known as the Denny Party, arrived from Illinois via Portland, Oregon, on the schooner Exact at Alki Point on November 13, 1851; the settlement was moved to the eastern shore of Elliott Bay and named "Seattle" in 1852, in honor of Chief Si'ahl of the local Duwamish and Suquamish tribes. Today, Seattle has high populations of Native, Scandinavian and Asian Americans, as well as a thriving LGBT community that ranks 6th in the United States for population. Logging was Seattle's first major industry, but by the late 19th century, the city had become a commercial and shipbuilding center as a gateway to Alaska during the Klondike Gold Rush. Growth after World War II was due to the local Boeing company, which established Seattle as a center for aircraft manufacturing; the Seattle area developed into a technology center from the 1980s onwards with companies like Microsoft becoming established in the region. Internet retailer Amazon was founded in Seattle in 1994, major airline Alaska Airlines is based in SeaTac, serving Seattle's international airport, Seattle–Tacoma International Airport.
The stream of new software and Internet companies led to an economic revival, which increased the city's population by 50,000 between 1990 and 2000. Owing to its increasing population in the 21st century and the state of Washington have some of the highest minimum wages in the country, at $15 per hour for smaller businesses and $16 for the city's largest employers. Seattle has a noteworthy musical history. From 1918 to 1951, nearly two dozen jazz nightclubs existed along Jackson Street, from the current Chinatown/International District to the Central District; the jazz scene nurtured the early careers of Ray Charles, Quincy Jones, Ernestine Anderson, others. Seattle is the birthplace of rock musician Jimi Hendrix, as well as the origin of the bands Nirvana, Pearl Jam, Alice in Chains, Foo Fighters and the alternative rock movement grunge. Archaeological excavations suggest that Native Americans have inhabited the Seattle area for at least 4,000 years. By the time the first European settlers arrived, the people occupied at least seventeen villages in the areas around Elliott Bay.
The first European to visit the Seattle area was George Vancouver, in May 1792 during his 1791–95 expedition to chart the Pacific Northwest. In 1851, a large party led by Luther Collins made a location on land at the mouth of the Duwamish River. Thirteen days members of the Collins Party on the way to their claim passed three scouts of the Denny Party. Members of the Denny Party claimed land on Alki Point on September 28, 1851; the rest of the Denny Party set sail from Portland and landed on Alki point during a rainstorm on November 13, 1851. After a difficult winter, most of the Denny Party relocated across Elliott Bay and claimed land a second time at the site of present-day Pioneer Square, naming this new settlement Duwamps. Charles Terry and John Low remained at the original landing location and reestablished their old land claim and called it "New York", but renamed "New York Alki" in April 1853, from a Chinook word meaning "by and by" or "someday". For the next few years, New York Alki and Duwamps competed for dominance, but in time Alki was abandoned and its residents moved across the bay to join the rest of the settlers.
David Swinson "Doc" Maynard, one of the founders of Duwamps, was the primary advocate to name the settlement after Chief Seattle of the Duwamish and Suquamish tribes. The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when the first plats for the village were filed. In 1855, nominal land settlements were established. On January 14, 1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of trustees managing the city; the Town of Seattle was disincorporated on January 18, 1867, remained a mere precinct of King County until late 1869, when a new petition was filed and the city was re-incorporated December 2, 1869, with a mayor–council government. The corporate seal of the City of Seattle carries the date "1869" and a likeness of Chief Sealth in left profile. Seattle has a history of boom-and-bust cycles, like many other cities near areas of extensive natural and mineral resources. Seattle has risen several times economically gone into precipitous decline, but it has used those periods to rebuild solid infrastructure
