Problem: Data compression:

To determine what information in an audio signal is perceptually irrelevant, most lossy compression algorithms use transforms such as the modified discrete cosine transform (MDCT) to convert time domain sampled waveforms into a transform domain. Once transformed, typically into the frequency domain, component frequencies can be allocated bits according to how audible they are. Audibility of spectral components calculated using the absolute threshold of hearing and the principles of simultaneous maskingthe phenomenon wherein a signal is masked by another signal separated by frequencyand, in some cases, temporal maskingwhere a signal is masked by another signal separated by time. Equal-loudness contours may also be used to weight the perceptual importance of components. Models of the human ear-brain combination incorporating such effects are often called psychoacoustic models.

What is the phenomenon wherein a signal is masked by another signal separated by threshold?

Problem: Microsoft released minimum hardware requirements for tablet and laplet devices to be "certified" for Windows 8, and defined a convertible form factor as a standalone device that combines the PC, display and rechargeable power source with a mechanically attached keyboard and pointing device in a single chassis. A convertible can be transformed into a tablet where the attached input devices are hidden or removed leaving the display as the only input mechanism. On March 12, 2013, Microsoft amended its certification requirements to only require that screens on tablets have a minimum resolution of 1024768 (down from the previous 1366768). The amended requirement is intended to allow "greater design flexibility" for future products.
How does a convertible become a tablet?

Context and question: Illustrated magazines for Western expatriates introduced Western-style satirical cartoons to Japan in the late 19th century. New publications in both the Western and Japanese styles became popular, and at the end of the 1890s, American-style newspaper comics supplements began to appear in Japan, as well as some American comic strips. 1900 saw the debut of the Jiji Manga in the Jiji Shinpo newspaperthe first use of the word "manga" in its modern sense, and where, in 1902, Rakuten Kitazawa began the first modern Japanese comic strip. By the 1930s, comic strips were serialized in large-circulation monthly girls' and boys' magazine and collected into hardback volumes.
When did comic supplements stop showing up in Japan?
Answer: unanswerable

Question: The Heian period (, Heian jidai?) is the last division of classical Japanese history, running from 794 to 1185. The period is named after the capital city of Heian-kyo, or modern Kyoto. It is the period in Japanese history when Buddhism, Taoism and other Chinese influences were at their height. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic family who had intermarried with the imperial family. Many emperors actually had mothers from the Fujiwara family. Heian (?) means "peace" in Japanese.
Is there an answer to this question: The Heian period was known for what types of art?

Answer: poetry and literature

QUES: Cyborg anthropology originated as a sub-focus group within the American Anthropological Association's annual meeting in 1993. The sub-group was very closely related to STS and the Society for the Social Studies of Science. Donna Haraway's 1985 Cyborg Manifesto could be considered the founding document of cyborg anthropology by first exploring the philosophical and sociological ramifications of the term. Cyborg anthropology studies humankind and its relations with the technological systems it has built, specifically modern technological systems that have reflexively shaped notions of what it means to be human beings.

What the sub-group of cyborg anthropology very closely related to, in addition to STS?
