DISK COMPRESSION [12 records]

Record 1 2019-02-11

English

Subject field(s)
  • Computer Memories
CONT

If you tell the system to load the compression driver into upper memory[, ] this will save 110 KB [kilobytes] of conventional memory when you are running in MS-DOS [Microsoft disk operating system] mode. However, the 110 KB of upper memory will force other drivers into conventional memory, causing the free conventional memory to decrease.

Record 2 2017-10-27

English

Subject field(s)
  • Symptoms (Medicine)
  • Musculoskeletal System
DEF

A test for nerve root compression in which intrathecal pressure and intraspinal fluid pressure are increased by bilateral manual compression of the jugular veins. Increase or aggravation of pain or sensory disturbance over the distribution of the involved nerve root confirms the presence of an extruded intervertebral disk or other mass.

OBS

Many refuse to perform this test because of the risks involved.

DEF

Manœuvre utilisée pour vérifier l'existence d'une irritation radiculaire. La compression manuelle bilatérale des veines jugulaires entraîne une augmentation de la pression du liquide céphalo-rachidien qui exacerbe la douleur sur le territoire du nerf affecté en cas de problème disco-radiculaire.

OBS

Plusieurs cliniciens se refusent à pratiquer cette manœuvre face aux risques qu'elle présente.

Disk space is less expensive than it used to be, and compression programs like zip and gzip can compress files very well and very fast. In addition, communication protocols such as modem protocols and HTTP/1. 1, the core protocol of the Web, can compress data on the fly, saving bandwidth as effectively as a binary format.

OBS

Subject field(s)

DEF

A procedure used to reduce the field of view of a [flame] detector by means of an opaque plate or card with a selected sized opening. This is frequently required to reduce refractory interference to acceptable levels.

CONT

The S512 with its PbS photo detector has a linear response from low to medium brightness flames, that is, no distortion of flame signal occurs with regard to any amplifier saturation or AGC action(compression). However, saturation will occur with the PbS element on bright flame. This condition can easily be rectified by using orificing(placing disk with small aperture in front of lens to reduce the amount of light or radiation).

Disruption on one side due to injury or spasm, results in asymmetrical forces which in turn can cause vertebral rotation, disk displacement or compression, and facet joint compression and distraction.

Although real motion video is the holy grail of multimedia, it still is impractical using today's technology. The current method for working with video is by capturing and converting the analog signal from a video source and either manipulating the image's data(which is written to video tape) or compressing the data using compression techniques(either software-only compression or a combination of hardware and software compression). To display or capture a single screen of an NTSC signal, you must have a video frame grabber. These are lowest on the rungs of the video ladder, in that they have less capability than boards that capture streaming video. These cards enable you to grab a single frame of video from a Laser Disk or a VCR. Video frame grabbers come in two varieties : single-frame capture and real-time capture. Single-frame capture boards enable you to freeze a selected frame and record it to your hard disk. In this function, single-frame boards are similar to scanners-they provide a means of capturing an image and saving it for use in a multimedia title.

CONT

Video compression ratios available from various vendors of full-motion video boards range up to 160 : 1 and perform adequately on standalone multimedia desktop platforms transmitting image data from CD-ROM or videodisk peripherals. However, these compression ratios will not be sufficient for effective transmission of complex videos and renderings that are being produced by engineering designers or even simpler videos in highly interactive multiuser networked environments. The solution, however, is already on the horizon in the form of fractional dimensional compression techniques(fractals) that can reach astonishing compression ratios of 10, 000 : 1. This is possible because fractals, despite their apparent complexity, have a very low information content and can be specified as relatively simple expressions. Fractal compression is obtained via mathematical functions that describe a sequence of transformations of an image and when applied repeatedly, converge on a unique fractal. Fractal compression algorithms can be incorporated in software or VLSI microchips and, if applied to a typical CD-ROM disk, should provide nearly seven hours of full-motion.

CONT

Le principe de la compression fractale réside dans la recherche de formes ou de motifs répétitifs dans une image, et dans le codage mathématique sous forme d'équations de ces motifs. Il est également possible de définir et d'exploiter des bibliothèques de motifs, afin d'améliorer la compression sur des séries d'images identiques.

A more sophisticated type of(rock bolt) tension indicator is the compression pad. This consists of a rubber disk sandwiched between two steel plate washers. The assemblage is installed in the manner of a bearing plate on the bolt. The amount by which the rubber disk extrudes around the periphery is proportional to the tension in the roof bolt and may be measured with a circular steel band which is graduated to read directly in pounds.
