Succession, английский
- A line of happenings, one after the other she had a succession of miscarriages.
- The orderly progression of changes in a community composition that occurs during development of vegetation in any area; from initial colonization to the attainment of the climax typical of a particular geographic area. micro s.: a dying tree, for example forced by winds to break causes a successional chain of events (also known as degrative succession. - see mosaic climax). autotropic s.: a temporal succession of species location principally involving plants. allogenic s.: a temporal succession of species at a location that is driven by external influences which alter conditions (contrary to autogenic); e.g. silt deposits changes a marshland to woodland. autogenic s.: a temporal succession of species at a location that is driven by processes operating with the community (contrary to allogenic), e.g. primary and secondary succession, that occur on newly exposed land. degraditive s.: degradable resources (feces, dead organisms) are utilized successively by a number of species; there is a link between succession on plant litter and soil formation. heterotrophic s.: a temporal succession of species at a location, principally involving animals. primary s.: soon after a region is denuded, a variety of pioneer species begin to colonize the bare ground and they modify the environmental conditions (e.g. a retreating glacier, early organisms provide the soils needed by succesing organisms - facilitation). secundary s.: follows major changes to an established ecosystem. catastrophic weather events, fire, or human activities all disturb the environment. after such an event on land, well-developed soil remains, giving pioneer species an easy foothold, but also on abandoned agricultural areas. order of s.: once an ecosystem is established, succesion does still take place on a smaller, slower, more complex scale. • degrative oos.: dead organic matter (feces etc ) trigger a succesional change of decomposing organisms until substance is completely recycled. • interactive oos.: interaction between species, e.g. herbivores in an habit; birds feed on caterpillar - too many caterpillars feeding on leaves can decrease competitiveness of plant, in which the bird lives. theories of s.: disturbances in ecosystems open up an area with the following scenarios: • facilitated: only certain pioneer species are capable of becoming established in the open space, but if certain species can exist and establish as adults under prevailing conditions, so that either can be: • tolerated: modification of the environment by early occupants has little or no effect on subsequent recruitment of later successional species, or • inhibited: occupants by early organisms make it less suitable for recruitment of late successional species, e.g. ulva sp.
- The passing of property or legal rights after death. the word commonly refers to the distribution of property under a state’s intestate succession laws, which determine who inherits property when someone dies without a valid will. when used in connection with real estate, the word refers to the passing of property by will or inheritance, as opposed to gift, grant, or purchase.
Compression, английский
- A state or condition of being pushed or shortened by a force.
- Сжатие
- Сжатие (данных), уменьшение размеров файла изображения. см. также lossy и non-lossy. процесс упаковки данных с целью уменьшения занимаемого ими пространства на накопителе
- Компрессия, сжатие
- The reduction of volume of a vapor or gas by mechanical means.
- Digital video pictures can be compressed with a number of techniques. these include: jpeg and jpeg-2000 (for still images), m-jpeg and mpeg (for moving pictures).
- The reduction in gain at one level of a picture signal with respect to the gain at another level of the same signal.
- A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. if each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. to make image files smaller almost every digital camera uses some form of compression. see the jpg entry below.
- The application of any of several techniques that reduce the amount of information required to represent that information in data transmission. this method reduces the required bandwidth and/or memory.
- A method of reducing the size of a digital image file to free up the storage capacity of memory cards and hard drives. compression technologies are distinguished from one another by whether or not they remove detail and color from the image. lossless technologies compress image data without removing detail, while "lossy" technologies compress images by removing some detail. joint photographic experts group (jpeg) is a lossy compression format supported by jpeg, pdf and postscript language file formats. most video formats are also lossy formats. tiff files are not and, as such, are far more stable than jpegs and other lossy file formats.
- Reducing the number of bits needed to encode a digital signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames).
- A digital photograph creates an image file that is enormous. to enable image files to become smaller and more manageable cameras employ some form of compression such as jpeg. raw and tiff files have no compression and take up more space.
- 1. the act of squeezing or pressing the first-aider applied compression to the chest of the casualty. 2. a serious condition in which the brain is compressed by blood or cerebrospinal fluid accumulating in it or by a fractured skull

- A reduction of the time available for a scheduled storyboard to reach its final state.
- A way of making files smaller, either to fit into restricted storage space or to speed up transmission over the internet. popular compression standards include- jpeg- and- gif- for pictures,- mp3for music files,- mpeg, mp4, avi- and- mov- for movie footage, and- zip- for just about everything else.

- Thinning or separation of particles in a propagating medium due to the decompression phase of a longitudinal ultrasonic cycle. opposite of compression. a compressional wave is composed of alternating compressions and rarefactions.
- Thinning or separation of particles in a propagating medium due to the decompression phase of an ultrasonic cycle. opposite of compression. a compressional wave is composed of alternating compressions and rarefactions.7,21
