Improvement, английский
- Улучшение; усовершенствование
- A structure or public utility or any other installation or physical change made in a property to increase its value and utility or to improve its appearance. in. abbr. for “inch.” inactive leaf, inactive door that leaf of a pair of doors which does not contain a lock, and to which the strike plate is fastened to receive the latch or bolt of the active leaf; usually it is fixed in a closed position by bolts at the top and bottom of the door. impervious cover 530 impluvium, a impost, 1
- The act of getting better the patient’s condition has shown a slight improvement. doctors have not detected any improvement in her asthma.
- Улучшение; усовершенствование; модернизация
Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).
Microscopic, английский
- Observable only with the aid of a microscope.
- Objects or organisms that are too small to be seen with the naked eye.
Sensitivity, английский
- Change in the response of a measuring instrument divided by the corresponding change in the stimulus (1)
- The ratio of the output of an instrument to the input (i.e. -gain).
- Defines the smallest signal detectable in the presence of systems noise
- In television, a factor expressing the incident illumination upon a specified scene required to produce a specified picture signal at the output terminals of a television camera.
- For a camera usually specified in lux to provide indication of light level required to gain a full video signal from the camera.
- A measure of the amount of light required to provide a standard video signal. sensitivity values are stated in lux (see lux) or foot-candles.
- Lens iris aperture required to provide a video output signal of standard level at a specified light input. in general, sensitivity is measured using an 89.9% reflectance grey scale chart illuminated by a 3200? k illuminance at 2000 lux (color camera) or 400 lux (b/w camera), for a video output level of 100%.
- 1. the fact of being able to detect and respond to an outside stimulus 2. the rate of positive responses in a test from persons with a specific disease. a high rate of sensitivity means a low rate of people being incorrectly classed as negative. compare specificity
- Чувствительность; сенситивность; восприимчивость специфически измененная реактивность. вероятность возникновения реакции на введение антигенов. ср. susceptibility (восприимчивость (к болезни)).
- The sensitivity of classification rule is a measure of its ability to correctly classify observations into a particular category. it is defined to be the ratio of the number of true positives to the number of positives in a test set. this value is usually inversely related to the specificity of the test for a given set of data and a particular classification rule. note that this measure is different from the positive predictive value of a rule, which is a measure of the probability that a positive is a true positive. if multiple classification categories exist, each category will have its own sensitivity, specificity, and positive predictive value. see also: positive predictive value, specificity.
- Чувствительность: a) различие в концентрации аналита, соответствующее наименьшему обнару-живаемому различию в реакции метода. представляется наклоном калибровоч-ной кривой. иногда ошибочно используется для обозначения предела обнаружения. b) частота истинно положительных результатов, полученных при испытании проб, в которых, насколько известно, содержится аналит [55]. c) отношение изменения показаний измерительного прибора к соответствую-щему изменению измеряемой величины. измеряемой величиной может быть, например, количество исследуемого вещества, содержащееся в пробе.
- Чувствительность. в сенсорном анализе — способность различать, идентифицировать и/или дифференцировать (качественно и/или количественно) один или более раздражителей с помощью органов чувств (предварительный стандарт мос, 12). в аналитической химии — чувствительность метода, которая (для простого-метода)- характеризуется наклоном калибровочной кривой, т. е. является дифференциалом измеряемой величины по отношению к концентрации dx/dc. чувствительность не следует путать с наименьшим количеством или наиболее низкой концентрацией, которые можно обнаружить с помощью данного метода; правильный термин для обозначения этого понятия — предел чувствительности (см. limit of detection).
- The output of a microphone in volts for a given input in sound pressure level. sensitivity can also mean the sound pressure level (spl) a loudspeaker produces at one meter when driven with one watt of pink noise.
- The degree of confidentiality of an e-mail message or calendar item, ranging from normal to confidential.
- The significance level that must be reached before a notification is sent.
- Чувствительность:
- Measure of a sensor’s ability to detect small signals. see resolution.
- Ability of a sensor or system to distinguish a signal or indication from background noise. see also probability of detection.
- Ability of a sensor or system to distinguish a signal or indication from background noise. see also probability of detection. si (international system of units): international measurement system in which the following seven
- (1) performance characteristic of a penetrant system, of a developer, or of an entire penetrant process that provides a relative measure of the ability to detect discontinuities. (2) enumerated level of performance of a penetrant system determined by applying standardized processing procedures on reference standards with known defects. (3) ability of a sensor or system to distinguish a signal or indication from background noise. compare probability of detection.
- Probability of detection.
- Ability of signal to change with small changes of measured quantity.

Restart / reset, английский
Special mode in which the ccd readout cycle is stopped and restarted in synchronization with an external event. in the stop mode, the ccd still accumulates picture information. rs-232c serial data transmission standard for computers which can also be used to control camera functions.
Partial enhance, английский
An advanced function of the digital signal processing (dsp) technology that allows a particular color to be selected and its hue, saturation and detail altered. this function gives the subject a pleasing complexion with a softer image while maintaining the sharpness of other areas, and vice versa. the designated active area of partial enhance can be set with the digital circuits by simply adjusting the area detect cursor.
