Problem: 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 input data symbols. It can achieve superior compression to other techniques such as the better-known Huffman algorithm. It uses an internal memory state to avoid the need to perform a one-to-one mapping of individual input symbols to distinct representations that use an integer number of bits, and it clears out the internal memory only after encoding the entire string of data symbols. Arithmetic coding applies especially well to adaptive data compression tasks where the statistics vary and are context-dependent, as it can be easily coupled with an adaptive model of the probability distribution of the input data. An early example of the use of arithmetic coding was its use as an optional (but not widely used) feature of the JPEG image coding standard. It has since been applied in various other designs including H.264/MPEG-4 AVC and HEVC for video coding.

Problem: The 1960s were less successful for the club, with Real Madrid monopolising La Liga. The completion of the Camp Nou, finished in 1957, meant the club had little money to spend on new players. The 1960s saw the emergence of Josep Maria Fusté and Carles Rexach, and the club won the Copa del Generalísimo in 1963 and the Fairs Cup in 1966. Barcelona restored some pride by beating Real Madrid 1–0 in the 1968 Copa del Generalísimo final at the Bernabéu in front of Franco, with coach Salvador Artigas, a former republican pilot in the civil war. With the end of Franco's dictatorship in 1974, the club changed its official name back to Futbol Club Barcelona and reverted the crest to its original design, including the original letters once again.
What competition did Barcelona win in 1966?
---
Answer: Fairs Cup


Problem: Machine vision systems often require bright and homogeneous illumination, so features of interest are easier to process. LEDs are often used for this purpose, and this is likely to remain one of their major uses until the price drops low enough to make signaling and illumination uses more widespread. Barcode scanners are the most common example of machine vision, and many low cost products use red LEDs instead of lasers. Optical computer mice are an example of LEDs in machine vision, as it is used to provide an even light source on the surface for the miniature camera within the mouse. LEDs constitute a nearly ideal light source for machine vision systems for several reasons:
