Frit compression

The frit-compression system was adapted from a Solid phase extraction (SPE) column, where a suspension of carbon nanotubes is squeezed between two polypropylene frits (70 micrometre pore diameter) inside a syringe column.

Graphics Interchange Format

In 1977 and 1978, Jacob Ziv and Abraham Lempel published a pair of papers on a new class of lossless data-compression algorithms, now collectively referred to as LZ77 and LZ78.

Herbert Akroyd Stuart

In the same year, Thomas Henry Barton (who later founded Barton Transport) at Hornsbys built a working high-compression version for experimental purposes, whereby the vaporiser was replaced with a cylinder head, therefore not relying on air being preheated, but by combustion through higher compression ratios.

Hispano-Suiza 12Y

The Armée de l'Air changed their nomenclature, so the next version was the Hispano-Suiza 12Y-21, which increased the compression ratio to 7:1, when running on 100 octane gasoline.

History of the Teller–Ulam design

The nuclear weapons designer Ted Taylor was clear about assigning credit for the basic staging and compression ideas to Ulam, while giving Teller the credit for recognizing the critical role of radiation as opposed to hydrodynamic pressure.

Hydraulic machinery

Flare fittings, are metal to metal compression seals deformed with a cone nut and pressed into a flare mating.

Jean-Loup Gailly

He wrote the compression code of the portable archiver of the Info-ZIP and the tools compatible with the PKZIP archiver for MS-DOS.

Jensen 541S

Jensen used their own powerful version of the Austin DS5 4 litre straight-six engine (featuring triple SU carburetors, a high compression Weslake head with custom-made twin exhaust manifolds and an alloy baffled sump/oil cooler) in the 541S.

Johnson-Grace

The founders later talked to Irving Reed at the University of Southern California, who had an idea for an improved image compression algoritihm, and started implementing such an algorithm; this became the ART image file format.

Jp2

JPEG 2000 (.jp2), a wavelet-based image compression standard

Kodak DCS 100

The DSU contained a 200 megabyte hard disk drive that could store up to 156 images without compression, or up to 600 images using a JPEG compatible compression board that was offered later as an optional extra.

Leveler

A leveler performs an audio process similar to compression, which is used to reduce the dynamic range of a signal, so that the quietest portion of the signal is loud enough to hear and the loudest portion is not too loud.

Macrium Reflect

Data is compressed and encrypted in real time using Abraham Lempel LZ based compression and AES encryption algorithms.

Mitsubishi Eclipse

The 1995–1999 turbo engines were given an increased compression ratio of 8.5:1, up from 7.8:1, and a smaller turbo, a Garrett T25 in place of the previous Mitsubishi TD04-13G (automatic cars) and TD05-14B (manual cars).

The second release was an EP of four-track recordings titled Everyday, Rock'n'Roll Is Saving My Life released by Space Baby in 2001, much more a back to basics affair with Franklin on his own playing simple melodic pop songs accompanied by electric and acoustic guitars, shakers, double-tracked vocals and the compression of the tape machine.

Twincharger

Additionally, the energy cost to drive a supercharger is higher than that of a turbocharger; if it is bypassed, the load of performing compression is removed, leaving only slight parasitic losses from spinning the working parts of the supercharger.

Voice compression

Time-compressed speech refers to voice compression for immediate playback, without any decompression (so that the final speech sounds faster to the listener).
