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 ...
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 )).
A millisecond (from milli-and second; symbol: ms) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 −3 or 1 / 1000) of a second or 1000 microseconds. A unit of 10 milliseconds may be called a centisecond , and one of 100 milliseconds a decisecond , but these names are rarely used. [3]
The QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart.It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates to the time taken from when the cardiac ventricles start to contract to when they finish relaxing.
The XPS One 24 has a WUXGA (1900×1200) resolution with 16.7 million colours, a 1200:1 contrast ratio, an 89° viewing angle, and a 6 millisecond response time. The 20-inch model has integrated High Definition Audio and 10-watt stereo speakers, while the 24-inch model has SoundBlaster Audigy HD software with 25-watt premium JBL speakers with an ...

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.
a volume-time curve, showing volume (litres) along the Y-axis and time (seconds) along the X-axis; a flow-volume loop, which graphically depicts the rate of airflow on the Y-axis and the total volume inspired or expired on the X-axis; Procedure. The basic forced volume vital capacity (FVC) test varies slightly depending on the equipment used.
