** Chirp spread spectrum ( CSS ) according to IEEE 802. 15. 4a CSS uses pseudo-stochastic coding

** A German Lorenz cipher machine operator sends a 4, 000-character message twice, allowing British mathematician Bill Tutte to decipher the machine's coding mechanism.

** Channel coding including

** Source coding ( digitization and data compression ), and information theory.

** Species altocumulus stratiformis ( Ac str ): Sheets or relatively flat patches of Ac ( synoptic coding determined by predominant variety or by genitus mother cloud ).

** Context-adaptive binary arithmetic coding ( CABAC ), an algorithm to losslessly compress syntax elements in the video stream knowing the probabilities of syntax elements in a given context.

** Context-adaptive variable-length coding ( CAVLC ), which is a lower-complexity alternative to CABAC for the coding of quantized transform coefficient values.

** A common simple and highly structured variable length coding ( VLC ) technique for many of the syntax elements not coded by CABAC or CAVLC, referred to as Exponential-Golomb coding ( or Exp-Golomb ).

** Spatial diversity coding is spatial coding that transmits replicas of the information signal along different spatial paths, so as to increase the reliability of the data transmission.

** Spatial interference cancellation coding

** Spatial multiplex coding

** Atkinson independently discovered the Midpoint circle algorithm for fast drawing of circles by using the sum of consecutive odd numbers.

** Mold-assisted reconstruction Made using laser scanning and 3D printing, a patient-specific silicone mold can be used as an aid during surgery.

** A natural science – one that seeks to elucidate the rules that govern the natural world using empirical and scientific method.

** Solar air conditioning, air conditioning using solar power

** Ice storage air conditioning, air conditioning using ice storage

** using some higher-level interface ( e. g. Video BIOS )

** using another lower-level device driver ( e. g. file system drivers using disk drivers )

** Røros and Nord-Noreg styles, both using the standard fiddle.

** Finnskogen, using the standard fiddle, but featuring some flatted notes influenced by Finnish folk music.

** Voss and Telemark styles, both using the Hardanger fiddle.

** For some verbs in some languages, the difference between perfective and imperfective conveys an additional meaning difference ; in such cases, the two aspects are typically translated using separate verbs in English.

** Gasoline can be made from carbon ( coal ) using the Fischer-Tropsch process

** Diesel fuel can be made from carbon using the Fischer-Tropsch process

** The Animas Ping is a pump / blood glucose meter combo that connect to each other using radio frequency.

** ISO 3166-1 numeric – three-digit country codes which are identical to those developed and maintained by the United Nations Statistics Division, with the advantage of script ( writing system ) independence, and hence useful for people or systems using non-Latin scripts.

** one of the humanities – academic discipline that study the human condition, using methods that are primarily analytical, critical, or speculative, as distinguished from the mainly empirical approaches of the natural sciences.

** Binary PSK ( BPSK ), using M = 2 symbols

** Quadrature PSK ( QPSK ), using M = 4 symbols

** 8PSK, using M = 8 symbols

** 16PSK, using M = 16 symbols

** KAMINI — A unique reactor using Uranium-233 isotope for fuel.

** India is also planning to build fast breeder reactors using the thorium – Uranium-233 fuel cycle.

** Sex drive is dependent on androgen levels only in the presence of estrogen, but without estrogen, free testosterone level actually decreases sexual desire ( instead of increases sex drive ), as demonstrated for those women who have hypoactive sexual desire disorder, and the sexual desire in these women can be restored by administration of estrogen ( using oral contraceptive ).

** Bosch EZF ignition system using dual distributors makes debut.

** The ability to use multiple motion vectors per macroblock ( one or two per partition ) with a maximum of 32 in the case of a B macroblock constructed of 16 4 × 4 partitions.

** The ability to use any macroblock type in B-frames, including I-macroblocks, resulting in much more efficient encoding when using B-frames.

** A lossless " PCM macroblock " representation mode in which video data samples are represented directly, allowing perfect representation of specific regions and allowing a strict limit to be placed on the quantity of coded data for each macroblock.

** An enhanced lossless macroblock representation mode allowing perfect representation of specific regions while ordinarily using substantially fewer bits than the PCM mode.

** Flexible macroblock ordering ( FMO ), also known as slice groups, and arbitrary slice ordering ( ASO ), which are techniques for restructuring the ordering of the representation of the fundamental regions ( macroblocks ) in pictures.
