An example of semi-elasticity is modified duration in bond trading. The opposite definition is sometimes used in the literature. That is, the term "semi-elasticity" is also sometimes used for the change (not percentage-wise) in f(x) in terms of a percentage change in x [9] which would be
The Encyclopedia of Science Fiction points to A Plunge into Space (Robert Cromie, 1890) [9] as having a subplot very similar to "The Cold Equations". [10] " A Weighty Decision" ( Al Feldstein in Weird Science , 1952) [ 11 ] and the story "Precedent" ( E. C. Tubb in New Worlds , 1952) [ 12 ] also have been cited as potential inspirations.
The y arc elasticity of x is defined as: , = % % where the percentage change in going from point 1 to point 2 is usually calculated relative to the midpoint: % = (+) /; % = (+) /. The use of the midpoint arc elasticity formula (with the midpoint used for the base of the change, rather than the initial point (x 1, y 1) which is used in almost all other contexts for calculating percentages) was ...
Expressed in terms of components with respect to a rectangular Cartesian coordinate system, the governing equations of linear elasticity are: [1]. Equation of motion: , + = where the (), subscript is a shorthand for () / and indicates /, = is the Cauchy stress tensor, is the body force density, is the mass density, and is the displacement.
Elasticity (economics), a general term for a ratio of change. For more specific economic forms of elasticity, see: Cross elasticity of demand; Elasticity of substitution; Frisch elasticity of labor supply; Income elasticity of demand; Output elasticity; Price elasticity of demand; Price elasticity of supply; Yield elasticity of bond value
The compatibility conditions in linear elasticity are obtained by observing that there are six strain-displacement relations that are functions of only three unknown displacements. This suggests that the three displacements may be removed from the system of equations without loss of information.
It is a paradox worthy of Zeno himself that significant dumbing-down is necessary in order to make tales of extraordinary genius comprehensible to us lay audiences. But in her own attempt at ...
Given the definition of the elasticity coefficient in terms of a partial derivative, it is possible, for example, to determine the elasticity of an arbitrary rate law by differentiating the rate law by the independent variable and scaling. For example, the elasticity coefficient for a mass-action rate law such as:
