# Lift coefficient (CL or CZ) (Aerodynamics) (dimensionless) - Relates the lift generated by an airfoil with the dynamic pressure of the fluid flow around the airfoil, and the plan-form area of the airfoil.
Spearman's rank correlation coefficient | Pearson product-moment correlation coefficient | Pearson's correlation coefficient r | Correlation coefficient | Coefficient of relationship | Seebeck coefficient | Rideal–Walker coefficient | Partition coefficient | Lift coefficient | correlation coefficient | Coefficient of determination | Binomial coefficient | Ballistic coefficient |
An example of such a special .338 calibre extreme range bullet is the German CNC manufactured mono-metal 18.92 gram (292 gr) LM-105 (G1 BC ≈ 0.93 – this Ballistic coefficient (BC) is calculated by its designer, Lutz Möller, and not proven by Doppler radar measurements).
An example of such a special .375 caliber extreme range bullet is the German CNC manufactured mono-metal 26.44 gram (408 gr) .375 Viking (G1 BC 1.537; this Ballistic coefficient (BC) is calculated by its designer, Mr. Lutz Möller, and not proven by Doppler radar measurements).
An example of such a special .416 Barrett very low drag extreme range bullet is the German CNC manufactured mono-metal 27.5 gram (424 gr) .416 Barrett MSG (G1 BC ≈ 1.103 – this ballistic coefficient (BC) is calculated by its designer, Mr. Lutz Möller, and not proven by Doppler radar measurements).
Ultrasound attenuation spectroscopy, instead of energy, the attenuation coefficient is measured versus frequency
Persu, a specialist in airplanes aerodynamics and dynamics, implemented his idea in 1922–1923 in Berlin, building an automobile with an incredibly low drag coefficient of 0.28 (same as a modern Porsche Carrera) or even 0.22 (still not reached by almost any modern production cars), depending on the source.
COCO includes a LITE version of COSMOtherm, an activity coefficient model based on Ab initio quantum chemistry methods.
In analogy to activity coefficient models used in chemical engineering, such as NRTL, UNIQUAC or UNIFAC, the final chemical potential can be split into a combinatorial and a residual (non ideal) contribution.
Cronbach's alpha, a coefficient of reliability developed by Lee Cronbach
His modesty is perhaps one of the reasons that the generalization of the Kuder-Richardson's (1937) formulation of the coefficient of internal consistency reliability to a continuous case is generally ascribed to Lee Cronbach (1951), even though this generalization was already made a decade earlier (Hoyt, 1941).
Later with Denis Evans and Gary Morriss in 1990 he proved that for certain classes of thermostatted nonequilibrium steady states the relevant transport coefficient the transport coefficient has a simple relation to the sum of the largest and smallest Lyapunov exponents describing the trajectory of the N-particle steady state system in phase space.
Corrado Gini (1884–1965), Italian statistician, demographer, sociologist and developer of the Gini coefficient
The Jaccard index, also known as the Jaccard similarity coefficient (originally coined coefficient de communauté by Paul Jaccard), is a statistic used for comparing the similarity and diversity of sample sets.
The coefficient before is in fact the Euler characteristic of the sphere (for the torus it vanishes).
The coefficient matrix must be positive to ensure that the equation is trace-preserving and completely positive.
Although the model is old it has the characteristic feature to describe extrema in the activity coefficient, which modern models like UNIQUAC, NRTL and Wilson cannot.
In 1932, Merle Randall authored two scientific papers with Mikkel Frandsen: “The Standard Electrode Potential of Iron and the Activity Coefficient of Ferrous Chloride,” and “Determination of the Free Energy of Ferrous Hydroxide from Measurements of Electromotive Force.”
In 1998, she and her then adviser Jon Keating conjectured a value for the leading coefficient of the asymptotics of the moments of the Riemann zeta function.
The newer Z-car had a drag coefficient of 0.30 and was powered by Japan's first mass-produced V6 engine instead of an I6.
Lyman Briggs and Homer LeRoy Shantz (1912) proposed the wilting coefficient, which is defined as the percentage water content of a soil when the plants growing in that soil are first reduced to a wilted condition from which they cannot recover in approximately saturated atmosphere without the addition of water to the soil (Taiz and Zeiger, 1991).
For example, the Rideal–Walker method gives a Rideal–Walker coefficient and the U.S. Department of Agriculture method gives a U.S. Department of Agriculture coefficient.
SCRIM, Sideway-force Coefficient Routine Investigation Machine
He is noted for the Breusch–Pagan test from the paper (with Adrian Pagan) "A simple test for heteroscedasticity and random coefficient variation" (see Noted works, below).
For example, a Sopwith Camel biplane of World War I which had many wires and bracing struts as well as fixed landing gear, had a zero-lift drag coefficient of approximately 0.0378.
