Gamma correction is a type of power law function whose exponent is the Greek letter gamma ( γ ). It should not be confused with the mathematical Gamma function. The lower case gamma, γ, is a parameter of the former; the upper case letter, Γ, is the name of (and symbol used for) the latter (as in Γ ( x )).
Lunar Laser Ranging Experiment from the Apollo 11 mission. Lunar Laser Ranging (LLR) is the practice of measuring the distance between the surfaces of the Earth and the Moon using laser ranging. The distance can be calculated from the round-trip time of laser light pulses travelling at the speed of light, which are reflected back to Earth by ...
The Venus flytrap is one of a very small group of plants that are capable of rapid movement. Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. For example, the Venus flytrap closes its trap in about 100 milliseconds. [1] The traps of Utricularia are much faster, closing ...
Interstimulus interval. The interstimulus interval (often abbreviated as ISI) is the temporal interval between the offset of one stimulus to the onset of another. For instance, Max Wertheimer did experiments with two stationary, flashing lights that at some interstimulus intervals appeared to the subject as moving instead of stationary.
The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the outputs of a general system when its inputs change from zero to one in a very short time.
Combined kinetic and gravitational time dilations. Combined, these sources of time dilation cause the clocks on the satellites to gain 38.6 microseconds per day relative to the clocks on the ground. This is a difference of 4.465 parts in 10 10. Without correction, errors of roughly 11.4 km/day would accumulate in the position.
Level is in dB and time is in seconds. The rise time, defined as the time it takes for the needle to reach 99% of the distance to 0 VU when the VU-meter is submitted to a signal that steps from 0 to a level that reads 0 VU, is 300 ms. The overshoot must be within 1 to 1.5%. The fall time is the same as the rise time, 300 ms. Frequency response
Peak programme meter. A typical British quasi-PPM. Each division between '1' and '7' is exactly four decibels and '6' is the intended maximum level. A peak programme meter ( PPM) is an instrument used in professional audio that indicates the level of an audio signal . Different kinds of PPM fall into broad categories:
