Compression algorithms can average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression.

* Compression ( zoology ) when an animal, or part of an animal, is shorter or narrower compared with other animals in the same group ; e. g. the body of a lizard may be " compressed " ( flattened ) so it can better fit into crevices under rocks

* Compression: the proxy server can optimize and compress the content to speed up the load time.

Compression failures can occur at both the macro scale or at each individual reinforcing fibre in compression buckling.

Higher Compression ratios also mean that the distance that the piston can push to produce power is greater ( which is called the Expansion ratio ).

* Compression of a gas, for example pneumatic shock absorbers, which can act like springs as the air pressure is building to resist the force on it.

Compression rates of up to 1: 500 can be achieved.

Compression, long-lens, or telephoto distortion can be seen in images shot from a distant using a long focus lens or the more common telephoto sub-type ( with an angle of view narrower than a normal lens ).

; Compression: Various schemes can be employed to shrink the size of the source data to be stored so that it uses less storage space.

Compression can travel in ' compression waves ' ( sound waves, for instance ), and rarefaction waves also exist in nature.

Compression of the optic chiasm can lead to bitemporal hemianopsia, and, when there is no relevant trauma, this clinical finding is pathognomonic for a pituitary tumor.

Compression can inhibit healing by hindering circulation.

Compression, trauma or other damage to this region of the spinal cord can result in cauda equina syndrome.

Compression fittings are especially useful in installations that may require occasional disassembly or partial removal for maintenance etc., since these joints can be broken and remade without affecting the integrity of the joint.

Compression can be improved by bounding n < sub > i </ sub > so that the model weighting is better balanced.

3Dc + ( FourCC: ATI1 ) ( also known as BC4 or Block Compression 4 ) can compress textures, i. e. light maps, shadow maps, HDR textures and material properties.

Compression braking can be greatly increased by opening the cylinders to the exhaust with a valve on downstroke while in overrun, which is often done on large trucks ( see Jake brake ).

Compression techniques ( e. g. multipole expansions or adaptive cross approximation / hierarchical matrices ) can be used to ameliorate these problems, though at the cost of added complexity and with a success-rate that depends heavily on the nature of the problem being solved and the geometry involved.

Other impact absorbing systems designed by Fitch are the Fitch Compression Barrier, suited for oval tracks and other such high speed situations with little runoff area, which comprises a set of strong, resilient hollow cylinders about a yard in diameter placed between the guardrail and the wall, gently absorbing the vehicle's energy without bouncing it back onto the track, and the Fitch Displaceable Guardrail where more room is available, a guardrail mounted on skids so that it can slide backwards on impact, gradually capturing the car.

Compression of one or both ureters can also be caused by other developmental defects not completely occurring during the fetal stage such as an abnormally placed vein, artery, or tumor.

Compression prevents recurrence of lymphedema, and in some lipedema patients can reduce the pain of lipedemic fat.

Compression by the uterus in late pregnancy, straining during parturition and mounting during estrus can increase the likelihood of the object penetrating the abdominal wall or the heart sac.

Compression uses an algorithm that stores an exact representation or an approximation of the original image in a smaller number of bytes that can be expanded back to its uncompressed form with a corresponding decompression algorithm.

Compression garments are meant to be worn every day to maintain edema reduction and must be replaced on a regular basis.

The user interface ( UI ) for Audio Compression Manager may be accessed through various programs that use it, including Sound Recorder in some versions of Windows.

The basic patents covering Fractal Image Compression, U. S. Patents 4, 941, 193, 5, 065, 447, 5, 384, 867, 5, 416, 856, and 5, 430, 812 appear to be expired.

Compression results in damage to the myelin sheath and manifests as delayed latencies and slowed conduction velocities However, normal electrodiagnostic studies do not preclude the presence of carpal tunnel syndrome, as a threshold of nerve injury must be reached before study results become abnormal and cut-off values for abnormality are variable.

Compression artifacts may intentionally be used as a visual style, sometimes known as glitch art.

The QuickTime Image Compression Manager integrated closely with QuickDraw: in particular, image decompression calls were full-fledged QuickDraw drawing calls, and if a picture was being recorded, the compressed data would be saved as part of the picture, for display when the picture was later drawn.

LTAC will not be developed any further since it has been superseded by its successor Lossless Predictive Audio Compression ( LPAC ), which is based on linear prediction.

* Compression: Dressings, bandages, or ace-wraps should be used to immobilize the sprain and provide support.

Compression of mixtures with a high fraction of oxygen are an increased fire hazard, and the compressor lubricant must be compatible to minimise this risk.

Compression of the dorsal root ganglion by a mechanical stimulus lowers the voltage threshold needed to evoke a response and causes action potentials to be fired.

Compression stockings should be at least 30 – 40 mm Hg and will work best if they are waist-high.

Compression stockings should be fitted to achieve the greatest benefit.

Compression fittings are also used extensively for hot and cold water faucets ( taps ) and toilet stop valves ; compression fittings are well suited to this application, as these valves are usually located in confined spaces where copper pipe would be difficult to solder without creating a fire hazard.

Compression is naively achieved by finding the lowest and highest values of the 16 pixels to be compressed and storing each of those as an 8-bit quantity.

The compressor uses vector quantization to determine the one or two band palette colors which best match each block and encodes runs of blocks as either one color byte or two color bytes plus a 16-bit vector which determines which pixel gets which color, similarly to S3 Texture Compression.

* Compression through external pressure by neighbouring structures or tumors, either by significantly compressing the vein or by promoting thrombosis by causing turbulence by disturbing the blood flow.

Lossless Transform Audio Compression ( LTAC ) is a compression algorithm developed by Tilman Liebchen, Marcus Purat and Peter Noll at Institute for Telecommunications, Technical University Berlin ( TU Berlin ), to compress PCM audio in a lossless manner, unlike conventional lossy audio compression algorithms ( like MP3 ).

S3 Texture Compression ( S3TC ) ( sometimes also called DXTn or DXTC ) is a group of related lossy texture compression algorithms originally developed by Iourcha et al.

3Dc ( FourCC: ATI2 ), also known as DXN, BC5, or Block Compression 5 is a lossy data compression algorithm for normal maps invented and first implemented by ATI.

* Compression: Controlled amounts of unwanted information may be generated as a result of the use of lossy compression techniques.
