Article: 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 lossless compression. Lossy compression reduces bits by identifying unnecessary information and removing it. The process of reducing the size of a data file is referred to as data compression. In the context of data transmission, it is called source coding (encoding done at the source of the data before it is stored or transmitted) in opposition to channel coding.

Question: What can be either lossy or lossless?
Ans: Compression

Article: Since the early 1950s on conventional carriers it has been the practice to recover aircraft at an angle to port of the axial line of the ship. The primary function of this angled deck is to allow aircraft that miss the arresting wires, referred to as a bolter, to become airborne again without the risk of hitting aircraft parked forward. The angled deck allows the installation of one or two "waist" catapults in addition to the two bow cats. An angled deck also improves launch and recovery cycle flexibility with the option of simultaneous launching and recovery of aircraft.

Question: What aircraft design feature improves launch and recovery cycle flexibilty?
Ans: An angled deck

Article: The university hosts a variety of student journals, magazines, and newspapers. Established in 1872, The Yale Record is the world's oldest humor magazine. Newspapers include the Yale Daily News, which was first published in 1878, and the weekly Yale Herald, which was first published in 1986. Dwight Hall, an independent, non-profit community service organization, oversees more than 2,000 Yale undergraduates working on more than 70 community service initiatives in New Haven. The Yale College Council runs several agencies that oversee campus wide activities and student services. The Yale Dramatic Association and Bulldog Productions cater to the theater and film communities, respectively. In addition, the Yale Drama Coalition serves to coordinate between and provide resources for the various Sudler Fund sponsored theater productions which run each weekend. WYBC Yale Radio is the campus's radio station, owned and operated by students. While students used to broadcast on AM & FM frequencies, they now have an Internet-only stream.

Question: In what year was the Yale Daily News established?
Ans: 1878

Article: The Mimamsa school has several subschools defined by epistemology. The Prabhakara subschool of Mimamsa considered five epistemically reliable means to gaining knowledge: pratyaksa (perception), anumana (inference), upamana (comparison and analogy), arthapatti (postulation, derivation from circumstances), and sabda (word, testimony of past or present reliable experts). The Kumarila Bhatta sub-school of Mimamsa added sixth to its canon of reliable epistemology - anupalabdi (non-perception, negative/cognitive proof).

Question: What is comparison and analogy in the Prabhakara school?
Ans:
upamana
