The Russian Empire known as Imperial Russia or Russia, was an empire that existed across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917. The third largest empire in world history, at its greatest extent stretching over three continents, Europe and North America, the Russian Empire was surpassed in landmass only by the British and Mongol empires; the rise of the Russian Empire coincided with the decline of neighboring rival powers: the Golden Horde, the Swedish Empire, the Polish–Lithuanian Commonwealth and the Ottoman Empire. It played a major role in 1812–1814 in defeating Napoleon's ambitions to control Europe and expanded to the west and south; the House of Romanov ruled the Russian Empire from 1721 until 1762, its matrilineal branch of patrilineal German descent the House of Holstein-Gottorp-Romanov ruled from 1762. At the beginning of the 19th century, the Russian Empire extended from the Arctic Ocean in the north to the Black Sea in the south, from the Baltic Sea on the west to the Pacific Ocean, into Alaska and Northern California in America on the east.
With 125.6 million subjects registered by the 1897 census, it had the third-largest population in the world at the time, after Qing China and India. Like all empires, it included a large disparity in terms of economics and religion. There were numerous dissident elements. Economically, the empire had a predominantly agricultural base, with low productivity on large estates worked by serfs, Russian peasants; the economy industrialized with the help of foreign investments in railways and factories. The land was ruled by a nobility from the 10th through the 17th centuries, subsequently by an emperor. Tsar Ivan III laid the groundwork for the empire that emerged, he tripled the territory of his state, ended the dominance of the Golden Horde, renovated the Moscow Kremlin, laid the foundations of the Russian state. Emperor Peter the Great fought numerous wars and expanded an huge empire into a major European power, he moved the capital from Moscow to the new model city of St. Petersburg, led a cultural revolution that replaced some of the traditionalist and medieval social and political mores with a modern, Europe-oriented, rationalist system.
Empress Catherine the Great presided over a golden age. Emperor Alexander II promoted numerous reforms, most the emancipation of all 23 million serfs in 1861, his policy in Eastern Europe involved protecting the Orthodox Christians under the rule of the Ottoman Empire. That connection by 1914 led to Russia's entry into the First World War on the side of France, the United Kingdom, Serbia, against the German and Ottoman empires; the Russian Empire functioned as an absolute monarchy on principles of Orthodoxy and Nationality until the Revolution of 1905 and became a de jure constitutional monarchy. The empire collapsed during the February Revolution of 1917 as a result of massive failures in its participation in the First World War. Though the Empire was only proclaimed by Tsar Peter I following the Treaty of Nystad, some historians would argue that it was born either when Ivan III of Russia conquered Veliky Novgorod in 1478, or when Ivan the Terrible conquered the Khanate of Kazan in 1552. According to another point of view, the term Tsardom, used after the coronation of Ivan IV in 1547, was a contemporary Russian word for empire.
Much of Russia's expansion occurred in the 17th century, culminating in the first Russian colonization of the Pacific in the mid-17th century, the Russo-Polish War that incorporated left-bank Ukraine, the Russian conquest of Siberia. Poland was divided in the 1790 -- 1815 era, with much of the population going to Russia. Most of the 19th-century growth came from adding territory in Asia, south of Siberia. Peter I the Great played a major role in introducing Russia to the European state system. While the vast land had a population of 14 million, grain yields trailed behind those of agriculture in the West, compelling nearly the entire population to farm. Only a small percentage lived in towns; the class of kholops, close in status to slavery, remained a major institution in Russia until 1723, when Peter converted household kholops into house serfs, thus including them in poll taxation. Russian agricultural kholops were formally converted into serfs earlier in 1679. Peter's first military efforts were directed against the Ottoman Turks.
His attention turned to the North. Peter still lacked a secure northern seaport, except at Archangel on the White Sea, where the harbor was frozen for nine months a year. Access to the Baltic was blocked by Sweden. Peter's ambitions for a "window to the sea" led him to make a secret alliance in 1699 with Saxony, the Polish–Lithuanian Commonwealth and Denmark against Sweden, resulting in the Great Northern War; the war ended in 1721. Peter acquired four provinces situated east of the Gulf of Finland; the coveted access to the sea was now secured. There he built Russia's new capital, Saint Petersburg, to replace Moscow, which had long been Russia's cultural center. In 1722, he tur
Integrated Authority File
The Integrated Authority File or GND is an international authority file for the organisation of personal names, subject headings and corporate bodies from catalogues. It is used for documentation in libraries and also by archives and museums; the GND is managed by the German National Library in cooperation with various regional library networks in German-speaking Europe and other partners. The GND falls under the Creative Commons Zero licence; the GND specification provides a hierarchy of high-level entities and sub-classes, useful in library classification, an approach to unambiguous identification of single elements. It comprises an ontology intended for knowledge representation in the semantic web, available in the RDF format; the Integrated Authority File became operational in April 2012 and integrates the content of the following authority files, which have since been discontinued: Name Authority File Corporate Bodies Authority File Subject Headings Authority File Uniform Title File of the Deutsches Musikarchiv At the time of its introduction on 5 April 2012, the GND held 9,493,860 files, including 2,650,000 personalised names.

Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. A simple example of a polarized transverse wave is vibrations traveling along a taut string. Depending on how the string is plucked, the vibrations can be in a vertical direction, horizontal direction, or at any angle perpendicular to the string. In contrast, in longitudinal waves, such as sound waves in a liquid or gas, the displacement of the particles in the oscillation is always in the direction of propagation, so these waves do not exhibit polarization. Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, transverse sound waves in solids. In some types of transverse waves, the wave displacement is limited to a single direction, so these do not exhibit polarization. An electromagnetic wave such as light consists of a coupled oscillating electric field and magnetic field which are always perpendicular.
In linear polarization, the fields oscillate in a single direction. In circular or elliptical polarization, the fields rotate at a constant rate in a plane as the wave travels; the rotation can have two possible directions. Light or other electromagnetic radiation from many sources, such as the sun and incandescent lamps, consists of short wave trains with an equal mixture of polarizations. Polarized light can be produced by passing unpolarized light through a polarizer, which allows waves of only one polarization to pass through; the most common optical materials are isotropic and do not affect the polarization of light passing through them. Some of these are used to make polarizing filters. Light is partially polarized when it reflects from a surface. According to quantum mechanics, electromagnetic waves can be viewed as streams of particles called photons; when viewed in this way, the polarization of an electromagnetic wave is determined by a quantum mechanical property of photons called their spin.
A photon has one of two possible spins: it can either spin in a right hand sense or a left hand sense about its direction of travel. Circularly polarized electromagnetic waves are composed of photons with only one type of spin, either right- or left-hand. Linearly polarized waves consist of photons that are in a superposition of right and left circularly polarized states, with equal amplitude and phases synchronized to give oscillation in a plane. Polarization is an important parameter in areas of science dealing with transverse waves, such as optics, seismology and microwaves. Impacted are technologies such as lasers and optical fiber telecommunications, radar. Most sources of light are classified as incoherent and unpolarized because they consist of a random mixture of waves having different spatial characteristics, frequencies and polarization states. However, for understanding electromagnetic waves and polarization in particular, it is easiest to just consider coherent plane waves. Characterizing an optical system in relation to a plane wave with those given parameters can be used to predict its response to a more general case, since a wave with any specified spatial structure can be decomposed into a combination of plane waves.
And incoherent states can be modeled stochastically as a weighted combination of such uncorrelated waves with some distribution of frequencies and polarizations. Electromagnetic waves, traveling in free space or another homogeneous isotropic non-attenuating medium, are properly described as transverse waves, meaning that a plane wave's electric field vector E and magnetic field H are in directions perpendicular to the direction of wave propagation. By convention, the "polarization" direction of an electromagnetic wave is given by its electric field vector. Considering a monochromatic plane wave of optical frequency f, let us take the direction of propagation as the z axis. Being a transverse wave the E and H fields must contain components only in the x and y directions whereas Ez = Hz = 0. Using complex notation, the instantaneous physical electric and magnetic fields are given by the real parts of the complex quantities occurring in the following equations; as a function of time t and spatial position z these complex fields can be written as: E → =
Kharkiv known as Kharkov, is the second-largest city in Ukraine. In the northeast of the country, it is the largest city of the Slobozhanshchyna historical region. Kharkiv is the administrative centre of Kharkiv Oblast and of the surrounding Kharkiv Raion, though administratively it is incorporated as a city of oblast significance and does not belong to the raion. Population: 1,439,036 The city was founded in 1654 and after a humble beginning as a small fortress grew to be a major centre of Ukrainian industry and culture in the Russian Empire. Kharkiv was the first capital of the Ukrainian Soviet Socialist Republic, from December 1919 to January 1934, after which the capital relocated to Kiev. Presently, Kharkiv is a major cultural, educational and industrial centre of Ukraine, with 6 museums, 7 theatres and 80 libraries, its industry specializes in machinery and in electronics. There are hundreds of industrial companies in the city, including the Morozov Design Bureau and the Malyshev Tank Factory.
Some sources offer that the city was named after Kharko. Among other names there are Charkow, Zakharpolis. Cultural artifacts date back to the Bronze Age, as well as those of Scythian and Sarmatian settlers. There is evidence that the Chernyakhov culture flourished in the area from the second to the sixth centuries; the city was founded by re-settlers who were running away from the war that engulfed Right-bank Ukraine in 1654. The years before the region was a sparsely populated part of the Cossack Hetmanate; the group of people came onto the banks of Lopan and Kharkiv rivers where an abandoned settlement stood. According to archive documents, the leader of the re-settlers was otaman Ivan Kryvoshlyk. At first the settlement was self-governed under the jurisdiction of a voivode from Chuhuiv, 40 kilometres to the east; the first appointed voivode from Moscow was Voyin Selifontov in 1656 who started to build a local ostrog. At that time the population of Kharkiv was just over 1000, half of whom were local cossacks, while Selifontov brought along a Moscow garrison of another 70 servicemen.
The first Kharkiv voivode was replaced in two years after complaining that locals refused to cooperate in building the fort. Kharkiv became the centre of the local Sloboda cossack regiment as the area surrounding the Belgorod fortress was being militarized. With the resettlement of the area by Ukrainians it came to be known as Sloboda Ukraine, most of, included under the jurisdiction of the Razryad Prikaz headed by a district official from Belgorod. By 1657 the Kharkiv settlement had a fortress with underground passageways. In 1658 Ivan Ofrosimov was appointed as the new voivode, who worked on forcing locals to kiss the cross to show loyalty to the Moscow tsar; the locals led by their otaman. However, with the election of the new otaman Tymish Lavrynov the community sent a request to the tsar to establish a local Assumption market, signed by deans of Kharkiv churches. Relationships with the neighboring Chuhuiv sometimes were non-friendly and their arguments were pacified by force. With the appointment of the third voivode Vasiliy Sukhotin was finished the construction of the city fort.
Meanwhile, Kharkiv had become the centre of Sloboda Ukraine. The Kharkiv Fortress was erected around the Assumption Cathedral and its castle was at University Hill, it was between today's streets: vulytsia Kvitky-Osnovianenko, Constitution Square, Rose Luxemburg Square, Proletarian Square, Cathedral Descent. The fortress had 10 towers: Chuhuivska Tower, Moskovska Tower, Vestovska Tower, Tainytska Tower, Lopanska Corner Tower, Kharkivska Corner Tower and others; the tallest was Vestovska, some 16 metres tall, while the shortest one was Tainytska which had a secret well 35 metres deep. The fortress had the Lopanski Gates. In 1689 the fortress was expanded and included the Saint-Pokrov Cathedral and Monastery, baptized and became the center of local eparchy. Coincidentally in the same year in the vicinity of Kharkiv in Kolomak, Ivan Mazepa was announced the Hetman of Ukraine. Next to the Saint-Pokrov Cathedral was located the Kharkiv Collegiate, transferred from Belgorod to Kharkiv in 1726. In the course of the administrative reform carried out in 1708 by Peter the Great, the area was included into Kiev Governorate.
Kharkiv is mentioned as one of the towns making a part of the governorate. In 1727, Belgorod Governorate was split off, Kharkiv moved to Belgorod Governorate, it was the center of Kharkiv Sloboda Cossack regiment. The regiment at some point was detached from Belgorod Governorate attached to it again, until in 1765, Sloboda Ukraine Governorate was established with the seat in Kharkiv. Kharkiv University was established in 1805 in the Palace of Governorate-General. Alexander Mikolajewicz Mickiewicz, brother of Adam Mickiewicz was a professor of law in the university, another celebrity Goethe searched for instructors for the school. In 1906 Ivan Franko received a doctorate in Russian linguistics here; the streets were first cobbled in the city centre in 1830. In 1844 the 90 m
Digital photography uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, digital publishing or printing; until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, processed in liquid chemical solutions to develop and stabilize the image. Digital photographs are created by computer-based photoelectric and mechanical techniques, without wet bath chemical processing; the first consumer digital cameras were marketed in the late 1990s. Professionals gravitated to digital and were won over when their professional work required using digital files to fulfill the demands of employers and/or clients, for faster turn-around than conventional methods would allow. Starting around 2007, digital cameras were incorporated in cell phones and in the following years, cell phone cameras became widespread due to their connectivity to social media websites and email.
Since 2010, the digital point-and-shoot and DSLR formats have seen competition from the mirrorless digital camera format, which provides better image quality than the point-and-shoot or cell phone formats but comes in a smaller size and shape than the typical DSLR. Many mirrorless cameras accept interchangeable lenses and have advanced features through an electronic viewfinder, which replaces the through-the-lens finder image of the SLR format. While digital photography has only recently become mainstream, the late 20th century saw many small developments leading to its creation; the first image of Mars was taken as the Mariner 4 flew by it on July 15, 1965, with a camera system designed by NASA/JPL. While not what we define as a digital camera, it used a comparable process, it used a video camera tube, followed by a digitizer, rather than a mosaic of solid state sensor elements. This produced a digital image, stored on tape for slow transmission back to Earth; the real history of digital photography as we know.
In 1951, the first digital signals were saved to magnetic tape via the first video tape recorder. Six years in 1957, the first digital image was produced through a computer by Russell Kirsch, it was an image of his son. In the late 1960s, Willard S. Boyle and George E. Smith, two physicists with Bell Labs, Inc. invented the charge-coupled device, a semiconductor circuit used in the first digital video cameras for television broadcasting. Their invention was recognized by a Nobel Prize in Physics in 2009; the first published color digital photograph was produced in 1972 by Michael Francis Tompsett using CCD sensor technology and was featured on the cover of Electronics Magazine. It was a picture of Margaret Thompsett; the Cromemco Cyclops, a digital camera developed as a commercial product and interfaced to a microcomputer, was featured in the February 1975 issue of Popular Electronics magazine. It used metal-oxide semiconductor technology for its image sensor; the first self-contained digital camera was created in 1975 by Steven Sasson of Eastman Kodak.
Sasson's camera used CCD image sensor chips developed by Fairchild Semiconductor in 1973. The camera weighed 8 pounds, recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels, took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise. While it was not until 1981 that the first consumer camera was produced by Sony, Inc. the groundwork for digital imaging and photography had been laid. The first commercially available digital camera was the 1990 Dycam Model 1, it used a CCD image sensor, stored pictures digitally, connected directly to a computer for downloading images. Offered to professional photographers for a hefty price, by the mid-to-late 1990s, due to technology advancements, digital cameras were available to the general public; the advent of digital photography gave way to cultural changes in the field of photography. Unlike with traditional photography, dark rooms and hazardous chemicals were no longer required for post-production of an image - images could now be processed and enhanced from behind a computer screen in one's own home.
This allowed for photographers to be more creative with their editing techniques. As the field became more popular, types of digital photography and photographers diversified. Digital photography took photography itself from a small somewhat elite circle, to one that encompassed many people; the camera phone helped popularize digital photography, along with the internet and social media. The first cell phones with built-in digital cameras were produced in 2000 by Samsung. Small and easy to use, camera phones have made digital photography ubiquitous in the daily life of the general public. According to research from KeyPoint Intelligence/InfoTrends, an estimated 400 billion digital photos were taken globally in 2011 and this will rise to 1.2 trillion photos in 2017. An estimated 85 percent of the photos taken in 2017 will be done with the smartphone rather than a traditional digital camera. Image sensors read the intensity of light, digital memory devices store the digital image information as RGB color space or as raw data.
The two main types of sensors are charge-coupled devices, in which the photocharge is shifted to a central charge-to-voltage converter, CMOS or active pixel sensors. Except for some linear array type of cameras at the highest-end and simple
Virtual International Authority File
The Virtual International Authority File is an international authority file. It is a joint project of several national libraries and operated by the Online Computer Library Center. Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities; this would present all the benefits of a common file without requiring a large investment of time and expense in the process. The project was initiated by the US Library of Congress, the German National Library and the OCLC on August 6, 2003; the Bibliothèque nationale de France joined the project on October 5, 2007. The project transitioned to being a service of the OCLC on April 4, 2012; the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together. A VIAF record receives a standard data number, contains the primary "see" and "see also" records from the original records, refers to the original authority records.
The data are available for research and data exchange and sharing. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol; the file numbers are being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAF's clustering algorithm is run every month; as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records.

Brockhaus and Efron Encyclopedic Dictionary
The Brockhaus and Efron Encyclopedic Dictionary is a comprehensive multi-volume encyclopedia in Russian. It contains 121,240 articles, 7,800 images, 235 maps, it was published in Imperial Russia in 1890–1907, as a joint venture of Leipzig and St Petersburg publishers. The articles were written by the prominent Russian scholars of the period, such as Dmitry Mendeleyev and Vladimir Solovyov. Reprints have appeared following the dissolution of the Soviet Union. In 1889, the owner of one of the St. Petersburg printing houses Ilya Efron on the initiative of Professor Semyon Vengerov signed an agreement with the German publishing house F. A. Brockhaus to make Russian translation of a large encyclopaedia Konversations-Lexikon, issued by this publishing house. To this end the Brockhaus-Efron joint stock company was established, they intended to translate the German publication with a more detailed account of issues related to Russia. It was supposed to release 16-18 volumes; the first 8 half-volumes were edited by Ivan Andrievsky.
The Brockhaus and Efron Encyclopedic Dictionary contains 121,240 entries, 7800 illustrations and 235 maps. The encyclopedia came out in two versions: one had 41 main and 2 additional volumes. Half-volumes have double numbering: e.g. 49 and 50 and on the title pages are numbered XXV and XXVa. In the years 1899-1902 the Small Brockhaus and Efron Encyclopedic Dictionary was produced. In the years 1911-1916 there appeared the New Encyclopedic Dictionary; the National Library of Russia holds proof-copies of the 30th, the 31st volumes.
