The government has also relaxed reporting laws, but these remain highly restrictive. In September 2011, several banned websites, including YouTube, Democratic Voice of Burma and Voice of America, were unblocked. A 2011 report by the Hauser Center for Nonprofit Organizations found that, while contact with the Myanmar go...
Following Thein Sein's first ever visit to the UK and a meeting with Prime Minister David Cameron, the Myanmar president declared that all of his nation's political prisoners will be released by the end of 2013, in addition to a statement of support for the well-being of the Rohingya Muslim community. In a speech at Ch...
Under British administration, Myanmar was the second-wealthiest country in South-East Asia. It had been the world's largest exporter of rice. Myanmar also had a wealth of natural and labour resources. British Burma began exporting crude oil in 1853, making it one of the earliest petroleum producers in the world. It pro...
During World War II, the British destroyed the major government buildings, oil wells and mines for tungsten, tin, lead and silver to keep them from the Japanese. Myanmar was bombed extensively by both sides. After independence, the country was in ruins with its major infrastructure completely destroyed. After a parliam...
The major agricultural product is rice, which covers about 60% of the country's total cultivated land area. Rice accounts for 97% of total food grain production by weight. Through collaboration with the International Rice Research Institute 52 modern rice varieties were released in the country between 1966 and 1997, he...
Many US and European jewellery companies, including Bulgari, Tiffany, and Cartier, refuse to import these stones based on reports of deplorable working conditions in the mines. Human Rights Watch has encouraged a complete ban on the purchase of Burmese gems based on these reports and because nearly all profits go to th...
The most popular available tourist destinations in Myanmar include big cities such as Yangon and Mandalay; religious sites in Mon State, Pindaya, Bago and Hpa-An; nature trails in Inle Lake, Kengtung, Putao, Pyin Oo Lwin; ancient cities such as Bagan and Mrauk-U; as well as beaches in Nabule, Ngapali, Ngwe-Saung, Mergu...
The most common way for travellers to enter the country seems to be by air. According to the website Lonely Planet, getting into Myanmar is problematic: "No bus or train service connects Myanmar with another country, nor can you travel by car or motorcycle across the border – you must walk across.", and states that, "I...
Flights are available from most countries, though direct flights are limited to mainly Thai and other ASEAN airlines. According to Eleven magazine, "In the past, there were only 15 international airlines and increasing numbers of airlines have began launching direct flights from Japan, Qatar, Taiwan, South Korea, Germa...
In December 2014, Myanmar signed an agreement to set up its first stock exchange. The Yangon Stock Exchange Joint Venture Co. Ltd will be set up with Myanma Economic Bank sharing 51 percent, Japan's Daiwa Institute of Research Ltd 30.25 percent and Japan Exchange Group 18.75 percent. The Yangon Stock Exchange (YSX) off...
The provisional results of the 2014 Myanmar Census show that the total population is 51,419,420. This figure includes an estimated 1,206,353 persons in parts of northern Rakhine State, Kachin State and Kayin State who were not counted. People who were out of the country at the time of the census are not included in the...
The Bamar form an estimated 68% of the population. 10% of the population are Shan. The Kayin make up 7% of the population. The Rakhine people constitute 4% of the population. Overseas Chinese form approximately 3% of the population. Myanmar's ethnic minority groups prefer the term "ethnic nationality" over "ethnic mino...
Mon, who form 2% of the population, are ethno-linguistically related to the Khmer. Overseas Indians are 2%. The remainder are Kachin, Chin, Rohingya, Anglo-Indians, Gurkha, Nepali and other ethnic minorities. Included in this group are the Anglo-Burmese. Once forming a large and influential community, the Anglo-Burmese...
Myanmar is home to four major language families: Sino-Tibetan, Tai–Kadai, Austro-Asiatic, and Indo-European. Sino-Tibetan languages are most widely spoken. They include Burmese, Karen, Kachin, Chin, and Chinese (mainly Hokkien). The primary Tai–Kadai language is Shan. Mon, Palaung, and Wa are the major Austroasiatic la...
Burmese, the mother tongue of the Bamar and official language of Myanmar, is related to Tibetan and Chinese language. It is written in a script consisting of circular and semi-circular letters, which were adapted from the Mon script, which in turn was developed from a southern Indian script in the 5th century. The earl...
Many religions are practised in Myanmar. Religious edifices and orders have been in existence for many years. Festivals can be held on a grand scale. The Christian and Muslim populations do, however, face religious persecution and it is hard, if not impossible, for non-Buddhists to join the army or get government jobs,...
According to Pew Research, 7% of the population identifies as Christian; 4% as Muslim; 1% follows traditional animistic beliefs; and 2% follow other religions, including Mahayana Buddhism, Hinduism, and East Asian religions. However, according to a US State Department's 2010 international religious freedom report, offi...
The educational system of Myanmar is operated by the government agency, the Ministry of Education. The education system is based on the United Kingdom's system due to nearly a century of British and Christian presences in Myanmar. Nearly all schools are government-operated, but there has been a recent increase in priva...
A diverse range of indigenous cultures exist in Myanmar, the majority culture is primarily Buddhist and Bamar. Bamar culture has been influenced by the cultures of neighbouring countries. This is manifested in its language, cuisine, music, dance and theatre. The arts, particularly literature, have historically been inf...
In a traditional village, the monastery is the centre of cultural life. Monks are venerated and supported by the lay people. A novitiation ceremony called shinbyu is the most important coming of age events for a boy, during which he enters the monastery for a short time. All male children in Buddhist families are encou...
British colonial rule introduced Western elements of culture to Burma. Burma's education system is modelled after that of the United Kingdom. Colonial architectural influences are most evident in major cities such as Yangon. Many ethnic minorities, particularly the Karen in the southeast and the Kachin and Chin who pop...
Mohinga is the traditional breakfast dish and is Myanmar's national dish. Seafood is a common ingredient in coastal cities such as Sittwe, Kyaukpyu, Mawlamyaing (formerly Moulmein), Mergui (Myeik) and Dawei, while meat and poultry are more commonly used in landlocked cities like Mandalay. Freshwater fish and shrimp hav...
Myanmar's first film was a documentary of the funeral of Tun Shein — a leading politician of the 1910s, who campaigned for Burmese independence in London. The first Burmese silent film Myitta Ne Thuya (Love and Liquor) in 1920 which proved a major success, despite its poor quality due to a fixed camera position and ina...
Jews originated as a national and religious group in the Middle East during the second millennium BCE, in the part of the Levant known as the Land of Israel. The Merneptah Stele appears to confirm the existence of a people of Israel, associated with the god El, somewhere in Canaan as far back as the 13th century BCE. T...
According to a report published in 2014, about 43% of all Jews reside in Israel (6.1 million), and 40% in the United States (5.7 million), with most of the remainder living in Europe (1.4 million) and Canada (0.4 million). These numbers include all those who self-identified as Jews in a socio-demographic study or were ...
The etymological equivalent is in use in other languages, e.g., يَهُودِيّ yahūdī (sg.), al-yahūd (pl.), and بَنُو اِسرَائِيل banū isrāʼīl in Arabic, "Jude" in German, "judeu" in Portuguese, "juif" in French, "jøde" in Danish and Norwegian, "judío" in Spanish, "jood" in Dutch, etc., but derivations of the word "Hebrew" ...
According to the Hebrew Bible narrative, Jewish ancestry is traced back to the Biblical patriarchs such as Abraham, Isaac and Jacob, and the Biblical matriarchs Sarah, Rebecca, Leah, and Rachel, who lived in Canaan around the 18th century BCE. Jacob and his family migrated to Ancient Egypt after being invited to live w...
Modern archaeology has largely discarded the historicity of the Patriarchs and of the Exodus story, with it being reframed as constituting the Israelites' inspiring national myth narrative. The Israelites and their culture, according to the modern archaeological account, did not overtake the region by force, but instea...
Although the Israelites were divided into Twelve Tribes, the Jews (being one offshoot of the Israelites, another being the Samaritans) are traditionally said to descend mostly from the Israelite tribes of Judah (from where the Jews derive their ethnonym) and Benjamin, and partially from the tribe of Levi, who had toget...
Israelites enjoyed political independence twice in ancient history, first during the periods of the Biblical judges followed by the United Monarchy.[disputed – discuss] After the fall of the United Monarchy the land was divided into Israel and Judah. The term Jew originated from the Roman "Judean" and denoted someone f...
Genetic studies on Jews show that most Jews worldwide bear a common genetic heritage which originates in the Middle East, and that they bear their strongest resemblance to the peoples of the Fertile Crescent. The genetic composition of different Jewish groups shows that Jews share a common genetic pool dating back 4,00...
The Hebrew Bible, a religious interpretation of the traditions and early national history of the Jews, established the first of the Abrahamic religions, which are now practiced by 54% of the world. Judaism guides its adherents in both practice and belief, and has been called not only a religion, but also a "way of life...
Judaism shares some of the characteristics of a nation, an ethnicity, a religion, and a culture, making the definition of who is a Jew vary slightly depending on whether a religious or national approach to identity is used. Generally, in modern secular usage Jews include three groups: people who were born to a Jewish f...
Historical definitions of Jewish identity have traditionally been based on halakhic definitions of matrilineal descent, and halakhic conversions. Historical definitions of who is a Jew date back to the codification of the Oral Torah into the Babylonian Talmud, around 200 CE. Interpretations of sections of the Tanakh, s...
According to historian Shaye J. D. Cohen, the status of the offspring of mixed marriages was determined patrilineally in the Bible. He brings two likely explanations for the change in Mishnaic times: first, the Mishnah may have been applying the same logic to mixed marriages as it had applied to other mixtures (Kil'ayi...
By the 1st century, Babylonia, to which Jews migrated to after the Babylonian conquest as well as after the Bar Kokhba revolt in 135 CE, already held a speedily growing population of an estimated 1,000,000 Jews, which increased to an estimated 2 million between the years 200 CE – 500 CE, both by natural growth and by i...
Other historians believe that conversion during the Roman era was limited in number and did not account for much of the Jewish population growth, due to various factors such as the illegality of male conversion to Judaism in the Roman world from the mid-2nd century. Another factor that would have made conversion diffic...
Within the world's Jewish population there are distinct ethnic divisions, most of which are primarily the result of geographic branching from an originating Israelite population, and subsequent independent evolutions. An array of Jewish communities was established by Jewish settlers in various places around the Old Wor...
Jews are often identified as belonging to one of two major groups: the Ashkenazim and the Sephardim. Ashkenazim, or "Germanics" (Ashkenaz meaning "Germany" in Hebrew), are so named denoting their German Jewish cultural and geographical origins, while Sephardim, or "Hispanics" (Sefarad meaning "Spain/Hispania" or "Iberi...
The divisions between all these groups are approximate and their boundaries are not always clear. The Mizrahim for example, are a heterogeneous collection of North African, Central Asian, Caucasian, and Middle Eastern Jewish communities that are no closer related to each other than they are to any of the earlier mentio...
Ashkenazi Jews represent the bulk of modern Jewry, with at least 70% of Jews worldwide (and up to 90% prior to World War II and the Holocaust). As a result of their emigration from Europe, Ashkenazim also represent the overwhelming majority of Jews in the New World continents, in countries such as the United States, Ca...
Hebrew is the liturgical language of Judaism (termed lashon ha-kodesh, "the holy tongue"), the language in which most of the Hebrew scriptures (Tanakh) were composed, and the daily speech of the Jewish people for centuries. By the 5th century BCE, Aramaic, a closely related tongue, joined Hebrew as the spoken language ...
For centuries, Jews worldwide have spoken the local or dominant languages of the regions they migrated to, often developing distinctive dialectal forms or branches that became independent languages. Yiddish is the Judæo-German language developed by Ashkenazi Jews who migrated to Central Europe. Ladino is the Judæo-Span...
Despite efforts to revive Hebrew as the national language of the Jewish people, knowledge of the language is not commonly possessed by Jews worldwide and English has emerged as the lingua franca of the Jewish diaspora. Although many Jews once had sufficient knowledge of Hebrew to study the classic literature, and Jewis...
Y DNA studies tend to imply a small number of founders in an old population whose members parted and followed different migration paths. In most Jewish populations, these male line ancestors appear to have been mainly Middle Eastern. For example, Ashkenazi Jews share more common paternal lineages with other Jewish and ...
Studies of autosomal DNA, which look at the entire DNA mixture, have become increasingly important as the technology develops. They show that Jewish populations have tended to form relatively closely related groups in independent communities, with most in a community sharing significant ancestry in common. For Jewish p...
The studies also show that the Sephardic Bnei Anusim (descendants of the "anusim" forced converts to Catholicism) of Iberia (estimated at about 19.8% of modern Iberia) and Ibero-America (estimated at least 10% of modern Ibero-America) have Sephardic Jewish origins within the last few centuries, while the Bene Israel an...
Between 1948 and 1958, the Jewish population rose from 800,000 to two million. Currently, Jews account for 75.4% of the Israeli population, or 6 million people. The early years of the State of Israel were marked by the mass immigration of Holocaust survivors in the aftermath of the Holocaust and Jews fleeing Arab lands...
More than half of the Jews live in the Diaspora (see Population table). Currently, the largest Jewish community outside Israel, and either the largest or second-largest Jewish community in the world, is located in the United States, with 5.2 million to 6.4 million Jews by various estimates. Elsewhere in the Americas, t...
Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kin...
Prior to 1948, approximately 800,000 Jews were living in lands which now make up the Arab world (excluding Israel). Of these, just under two-thirds lived in the French-controlled Maghreb region, 15–20% in the Kingdom of Iraq, approximately 10% in the Kingdom of Egypt and approximately 7% in the Kingdom of Yemen. A furt...
Since at least the time of the Ancient Greeks, a proportion of Jews have assimilated into the wider non-Jewish society around them, by either choice or force, ceasing to practice Judaism and losing their Jewish identity. Assimilation took place in all areas, and during all time periods, with some Jewish communities, fo...
Rates of interreligious marriage vary widely: In the United States, it is just under 50%, in the United Kingdom, around 53%; in France; around 30%, and in Australia and Mexico, as low as 10%. In the United States, only about a third of children from intermarriages affiliate with Jewish religious practice. The result is...
In the Papal States, which existed until 1870, Jews were required to live only in specified neighborhoods called ghettos. In the 19th and (before the end of World War II) 20th centuries, the Roman Catholic Church adhered to a distinction between "good antisemitism" and "bad antisemitism". The "bad" kind promoted hatred...
Islam and Judaism have a complex relationship. Traditionally Jews and Christians living in Muslim lands, known as dhimmis, were allowed to practice their religions and administer their internal affairs, but they were subject to certain conditions. They had to pay the jizya (a per capita tax imposed on free adult non-Mu...
Notable exceptions include the massacre of Jews and forcible conversion of some Jews by the rulers of the Almohad dynasty in Al-Andalus in the 12th century, as well as in Islamic Persia, and the forced confinement of Moroccan Jews to walled quarters known as mellahs beginning from the 15th century and especially in the...
Throughout history, many rulers, empires and nations have oppressed their Jewish populations or sought to eliminate them entirely. Methods employed ranged from expulsion to outright genocide; within nations, often the threat of these extreme methods was sufficient to silence dissent. The history of antisemitism include...
The persecution reached a peak in Nazi Germany's Final Solution, which led to the Holocaust and the slaughter of approximately 6 million Jews. Of the world's 15 million Jews in 1939, more than a third were killed in the Holocaust. The Holocaust—the state-led systematic persecution and genocide of European Jews (and cer...
There is also a trend of Orthodox movements pursuing secular Jews in order to give them a stronger Jewish identity so there is less chance of intermarriage. As a result of the efforts by these and other Jewish groups over the past 25 years, there has been a trend (known as the Baal Teshuva movement) for secular Jews to...
The fiber is most often spun into yarn or thread and used to make a soft, breathable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated from 5000 BC have been excavated in Mexico and the Indus Valley Civilization in Ancient India (modern-day Pakistan and some p...
The earliest evidence of cotton use in South Asia has been found at the site of Mehrgarh, Pakistan, where cotton threads have been found preserved in copper beads; these finds have been dated to Neolithic (between 6000 and 5000 BCE). Cotton cultivation in the region is dated to the Indus Valley Civilization, which cove...
In Iran (Persia), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran. In Persian poets' poems, especially Ferdowsi's Shahname, there are references to co...
Though known since antiquity the commercial growing of cotton in Egypt only started in 1820's, following a Frenchman, by the name of M. Jumel, propositioning the then ruler, Mohamed Ali Pasha, that he could earn a substantial income by growing an extra-long staple Maho (Barbadence) cotton, in Lower Egypt, for the Frenc...
During the late medieval period, cotton became known as an imported fiber in northern Europe, without any knowledge of how it was derived, other than that it was a plant. Because Herodotus had written in his Histories, Book III, 106, that in India trees grew in the wild producing wool, it was assumed that the plant was...
India's cotton-processing sector gradually declined during British expansion in India and the establishment of colonial rule during the late 18th and early 19th centuries. This was largely due to aggressive colonialist mercantile policies of the British East India Company, which made cotton processing and manufacturing...
The advent of the Industrial Revolution in Britain provided a great boost to cotton manufacture, as textiles emerged as Britain's leading export. In 1738, Lewis Paul and John Wyatt, of Birmingham, England, patented the roller spinning machine, as well as the flyer-and-bobbin system for drawing cotton to a more even thi...
Production capacity in Britain and the United States was improved by the invention of the cotton gin by the American Eli Whitney in 1793. Before the development of cotton gins, the cotton fibers had to be pulled from the seeds tediously by hand. By the late 1700s a number of crude ginning machines had been developed. H...
By the 1840s, India was no longer capable of supplying the vast quantities of cotton fibers needed by mechanized British factories, while shipping bulky, low-price cotton from India to Britain was time-consuming and expensive. This, coupled with the emergence of American cotton as a superior type (due to the longer, st...
During the American Civil War, American cotton exports slumped due to a Union blockade on Southern ports, and also because of a strategic decision by the Confederate government to cut exports, hoping to force Britain to recognize the Confederacy or enter the war. This prompted the main purchasers of cotton, Britain and...
Cotton remained a key crop in the Southern economy after emancipation and the end of the Civil War in 1865. Across the South, sharecropping evolved, in which landless black and white farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs them...
Successful cultivation of cotton requires a long frost-free period, plenty of sunshine, and a moderate rainfall, usually from 600 to 1,200 mm (24 to 47 in). Soils usually need to be fairly heavy, although the level of nutrients does not need to be exceptional. In general, these conditions are met within the seasonally ...
Genetically modified (GM) cotton was developed to reduce the heavy reliance on pesticides. The bacterium Bacillus thuringiensis (Bt) naturally produces a chemical harmful only to a small fraction of insects, most notably the larvae of moths and butterflies, beetles, and flies, and harmless to other forms of life. The g...
But Bt cotton is ineffective against many cotton pests, however, such as plant bugs, stink bugs, and aphids; depending on circumstances it may still be desirable to use insecticides against these. A 2006 study done by Cornell researchers, the Center for Chinese Agricultural Policy and the Chinese Academy of Science on ...
GM cotton acreage in India grew at a rapid rate, increasing from 50,000 hectares in 2002 to 10.6 million hectares in 2011. The total cotton area in India was 12.1 million hectares in 2011, so GM cotton was grown on 88% of the cotton area. This made India the country with the largest area of GM cotton in the world. A lo...
Organic cotton is generally understood as cotton from plants not genetically modified and that is certified to be grown without the use of any synthetic agricultural chemicals, such as fertilizers or pesticides. Its production also promotes and enhances biodiversity and biological cycles. In the United States, organic ...
Historically, in North America, one of the most economically destructive pests in cotton production has been the boll weevil. Due to the US Department of Agriculture's highly successful Boll Weevil Eradication Program (BWEP), this pest has been eliminated from cotton in most of the United States. This program, along wi...
Most cotton in the United States, Europe and Australia is harvested mechanically, either by a cotton picker, a machine that removes the cotton from the boll without damaging the cotton plant, or by a cotton stripper, which strips the entire boll off the plant. Cotton strippers are used in regions where it is too windy ...
The era of manufactured fibers began with the development of rayon in France in the 1890s. Rayon is derived from a natural cellulose and cannot be considered synthetic, but requires extensive processing in a manufacturing process, and led the less expensive replacement of more naturally derived materials. A succession ...
Beginning as a self-help program in the mid-1960s, the Cotton Research and Promotion Program (CRPP) was organized by U.S. cotton producers in response to cotton's steady decline in market share. At that time, producers voted to set up a per-bale assessment system to fund the program, with built-in safeguards to protect...
Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; cambric, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and mos...
The cottonseed which remains after the cotton is ginned is used to produce cottonseed oil, which, after refining, can be consumed by humans like any other vegetable oil. The cottonseed meal that is left generally is fed to ruminant livestock; the gossypol remaining in the meal is toxic to monogastric animals. Cottonsee...
Cotton linters are fine, silky fibers which adhere to the seeds of the cotton plant after ginning. These curly fibers typically are less than 1⁄8 inch (3.2 mm) long. The term also may apply to the longer textile fiber staple lint as well as the shorter fuzzy fibers from some upland species. Linters are traditionally us...
Cotton lisle is a finely-spun, tightly twisted type of cotton that is noted for being strong and durable. Lisle is composed of two strands that have each been twisted an extra twist per inch than ordinary yarns and combined to create a single thread. The yarn is spun so that it is compact and solid. This cotton is used...
The largest producers of cotton, currently (2009), are China and India, with annual production of about 34 million bales and 33.4 million bales, respectively; most of this production is consumed by their respective textile industries. The largest exporters of raw cotton are the United States, with sales of $4.9 billion...
The 25,000 cotton growers in the United States of America are heavily subsidized at the rate of $2 billion per year although China now provides the highest overall level of cotton sector support. The future of these subsidies is uncertain and has led to anticipatory expansion of cotton brokers' operations in Africa. Du...
While Brazil was fighting the US through the WTO's Dispute Settlement Mechanism against a heavily subsidized cotton industry, a group of four least-developed African countries – Benin, Burkina Faso, Chad, and Mali – also known as "Cotton-4" have been the leading protagonist for the reduction of US cotton subsidies thro...
In addition to concerns over subsidies, the cotton industries of some countries are criticized for employing child labor and damaging workers' health by exposure to pesticides used in production. The Environmental Justice Foundation has campaigned against the prevalent use of forced child and adult labor in cotton prod...
A public genome sequencing effort of cotton was initiated in 2007 by a consortium of public researchers. They agreed on a strategy to sequence the genome of cultivated, tetraploid cotton. "Tetraploid" means that cultivated cotton actually has two separate genomes within its nucleus, referred to as the A and D genomes. ...
The public sector effort continues with the goal to create a high-quality, draft genome sequence from reads generated by all sources. The public-sector effort has generated Sanger reads of BACs, fosmids, and plasmids as well as 454 reads. These later types of reads will be instrumental in assembling an initial draft of...
In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lo...
Compression is useful because it helps reduce resource usage, such as data storage space or transmission capacity. Because compressed data must be decompressed to use, this extra processing imposes computational or other costs through decompression; this situation is far from being a free lunch. Data compression is sub...
Lossless data compression algorithms usually exploit statistical redundancy to represent data without losing any information, so that the process is reversible. Lossless compression is possible because most real-world data exhibits statistical redundancy. For example, an image may have areas of colour that do not chang...
The Lempel–Ziv (LZ) compression methods are among the most popular algorithms for lossless storage. DEFLATE is a variation on LZ optimized for decompression speed and compression ratio, but compression can be slow. DEFLATE is used in PKZIP, Gzip and PNG. LZW (Lempel–Ziv–Welch) is used in GIF images. Also noteworthy is ...
In a further refinement of the direct use of probabilistic modelling, statistical estimates can be coupled to an algorithm called arithmetic coding. Arithmetic coding is a more modern coding technique that uses the mathematical calculations of a finite-state machine to produce a string of encoded bits from a series of ...
Lossy data compression is the converse of lossless data compression. In these schemes, some loss of information is acceptable. Dropping nonessential detail from the data source can save storage space. Lossy data compression schemes are designed by research on how people perceive the data in question. For example, the h...
In lossy audio compression, methods of psychoacoustics are used to remove non-audible (or less audible) components of the audio signal. Compression of human speech is often performed with even more specialized techniques; speech coding, or voice coding, is sometimes distinguished as a separate discipline from audio com...
There is a close connection between machine learning and compression: a system that predicts the posterior probabilities of a sequence given its entire history can be used for optimal data compression (by using arithmetic coding on the output distribution) while an optimal compressor can be used for prediction (by find...
Data compression can be viewed as a special case of data differencing: Data differencing consists of producing a difference given a source and a target, with patching producing a target given a source and a difference, while data compression consists of producing a compressed file given a target, and decompression cons...
Audio data compression, not to be confused with dynamic range compression, has the potential to reduce the transmission bandwidth and storage requirements of audio data. Audio compression algorithms are implemented in software as audio codecs. Lossy audio compression algorithms provide higher compression at the cost of...
Lossless audio compression produces a representation of digital data that decompress to an exact digital duplicate of the original audio stream, unlike playback from lossy compression techniques such as Vorbis and MP3. Compression ratios are around 50–60% of original size, which is similar to those for generic lossless...
