a number One meaning is the number in front of a term in a function Or else it can mean a number measuring a physical quantity In the expression 3x^2 + 5x - 2, the coefficient of the quadratic term is 3 Or else it can mean a number measuring a physical quantity e g the coefficient of expansion is alpha = 0 00023
A numerical or constant multiplier of the variable in an algebraic term For example: 4x : coefficient is 4
A coefficient is a number that expresses a measurement of a particular quality of a substance or object under specified conditions. production coefficients. the number by which an unknown quantity is multiplied (coefficiens, from co- ( CO-) + efficiens ( EFFICIENT))
a statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation); "what is the correlation between those two variables?
A measure of the interdependence of two random variables that ranges in value from -1 to +1, indicating perfect negative correlation at -1, absence of correlation at zero, and perfect positive correlation at +1. Also called coefficient of correlation
The fraction of light absorbed per unit distance in a participating medium In SI units, this is specified as a fraction per meter In Radiance, the absorption is given separately for red, green, and blue
Electromagnetic radiation may be absorbed by an atom or a molecule Different atoms and molecules are likely to absorb different wavelengths of radiation For example the yellow wavelength at about 590 µm is easily absorbed, and emitted, by sodium vapour giving sodium street lamps their characteristic yellow colour The probability of a photon of electromagnetic radiation being absorbed when it encounters an atom or molecule is known as the absorption coefficient A value of 1 0 means a probability of 100% absorption and a value of 0 5 a probability of 50% absorption Cool objects such as interstellar dense clouds will contain molecules which will tend to absorb in the infra red region of the electromagnetic spectrum
In reference to a solar energy conversion devices, the degree to which a substance will absorb solar energy In a solar photovoltaic device, the factor by which photons are absorbed as they travel a unit distance through a material
A measure of the amount of radiant energy, incident normal to a planar surface, that is absorbed per unit distance or unit mass of a substance (Source: Carbon Dioxide Information Analysis Center, 1990)
A measure of the attenuation caused by absorption of energy that results from its passage through a medium [After 2196] Note 1: Absorption coefficients are usually expressed in units of reciprocal distance Note 2: The sum of the absorption coefficient and the scattering coefficient is the attenuation coefficient
A measure of the extinction due to absorption of monochromatic radiation as it traverses a medium Usually expressed as a volume absorption coefficient, kv, with units of reciprocal length (i e , area per unit volume), but also as a mass absorption coefficient, km, with units of area per unit mass The two are related by kv km, where is the density of the absorber See also absorption optical thickness
The energy of sound waves being taken in (entering) the surface of any material rather than being bounced off or reflected; usually given in octave bands Materials are rated in terms of their ability to absorb sounds
a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber; "absorptance equals 1 minus transmittance
A number characterizing the extent to which specified gamma (or X) rays transfer their energy to a material through which they pass The linear energy absorption coefficient is a measure of the energy transfer (or absorption) per unit thickness of material and is stated in units of reciprocal length (or thickness) The mass energy absorption coefficient is equal to the linear absorption coefficient divided by the density of the absorbing material; it is a measure of the energy absorption per unit mass See Attenuation coefficient
Number expressing the ratio of a substance's chemical activity to its molar concentration (see mole). The measured concentration of a substance may not be an accurate indicator of its chemical effectiveness as represented by the equation for a particular reaction; in such cases, the activity is calculated by multiplying the concentration by the activity coefficient. In solutions, the activity coefficient is a measure of how much the solution differs from an ideal solution
Coefficients are the number part of the terms with variables In 3x2 + 2y + 7xy + 5, the coefficient of the first term is 3 The coefficient of the second term is 2, and the coefficient of the third term is 7
A measure of the aerodynamic sleekness of an object Drag coefficient is signified by "dc : The lower the number, the greater the aerodynamic efficiency The higher the drag coefficient, the more a car's engine must work to keep a given road speed Also known as "CD" for coefficient of drag "
Ratio of the concentrations of a substance in solution in two phases which are in equilibrium The octanol/ water partition coefficient (Kow) is commonly used as an index of toxicity - solubility in octanol mimics solubility in biological lipid membranes which is related to potential for bioconcentration For convenience, the value is often expressed in logarithmic (base 10) form (log Kow)
The partition coefficient is the constant ratio that is found when a heterogeneous system of two phases is in equilibrium; the ratio of the concentrations (or strictly activities) of the same molecular species in the two phases is constant at constant temperature and pressure
A measure of the mass of solute per unit volume of stationary phase divided by the mass of solute per unit volume of mobile phase It is directly related to the distribution coefficient by the phase ratio
when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line
