Jitter, английский
- Дрожание, флуктуация. быстрые небольшие скачки вверх-вниз символов или точек на экране дисплея
- Дрожь
- Фазовая разность между сигналом, исходящим от источника, и сигналом, поступившем на приёмник
- Small, rapid variations in a waveform due to mechanical disturbances or to changes in the characteristic of components. supply voltages, imperfect synchronizing signals, circuits, etc.
- The variation in time of a received signal compared to the instance of its transmission or compared to a fixed time frame at the receiver. examples of jitter sources include signal-pattern-dependent laser turn-on delay jitter, noiseinduced jitter on a gating turn-on point, gating hysteresis jitter, and gating jitter that accumulates in a link between two nodes
- Small and rapid variations in the timing of a waveform due to noise, changes in component characteristics, supply voltages, imperfect synchronizing circuits, etc. see also ddj, dcd, and rj. also called phase jitter, timing distortion, or inter-symbol interference. the slight movement of a transmission signal in time or phase that can introduce errors and loss of synchronization. the amount of jitter will increase with longer cables, cables with higher attenuation, and signals at higher data rates.

- One method to avoid over-fitting is to use jittering in training data. noise is deliberately added to the training data. this is a sampling-based form of smoothing and works well when the model is trying to estimate a smooth relationship. this technique will, however, obscure any discontinuities that are in the underlying relationship. this is closely related to such techniques as kernel techniques, where the data points are replaced by multivariate distributions and ridge regressions, which add "prior" information to the regression function. choosing the size of the jitter is equivalent to the statistical problem of choosing a kernel bandwidth or the size of the prior information in the ridge regression. see also: kernel function, kernel regression. j-measure the j-measure is a scoring rule for association rules. in evaluation of a rule of the form "if x occurs, then y will occur," with a given frequency (support) and confidence, the j-measure provides a single measure that trades off rule frequency and rule confidence. the j-measure is the product of the probability of x, the if part of the rule, with the cross-entropy of the rule. see also: association rules, cross entropy.
Jitter distortion, английский

Jitterbug, английский
- A tamper, usually pneumatic, for concrete. job 1.

Pulse, английский
- A discontinuous burst of laser, light or energy, as opposed to a continuous beam. a true pulse achieves higher peak powers than that attainable in a cw output.
- A current or voltage which changes abruptly from one value to another and back to the original value in a finite length of time. used to describe one particular variation in a series of wave motions. the parts of the pulse include the rise time, fall time, and pulse width, pulse amplitude. the period of a pulse refers to the amount of time between pulses.
- Pulso
- The regular expansion and contraction of an artery caused by the heart pumping blood through the body, which can be felt with the fingers especially where an artery is near the surface of the body, as in the wrist or neck her pulse is very irregular. to take or feel a person’s pulse to measure a person’s pulse rate by pressing on the skin above an artery with the fingers has the patient’s pulse been taken? comment: the standard adult pulse is about 72 beats per minute, but it is higher in children. the pulse is usually taken by placing the fingers on the patient’s wrist, at the point where the radial artery passes through the depression just below the thumb.
- A brief emission of radio energy by a radar system. the detection and ranging part of the acronym is accomplished by timing the delay between transmission of radio energy and its subsequent return.
- Импульс
- Heart rate. normal adult resting heart rate varies among horses but is usually 40 beats per minute.
- Transient electrical or ultrasonic signal that has a rapid increase in amplitude to its maximum value, followed by an immediate return.
- Transient electrical or ultrasonic signal that has a rapid increase in amplitude to its maximum value, followed by an immediate return.16
