A "'biquad filter "'is a type of linear filter that implements a transfer function that is the ratio of two quadratic functions.
22.
In order to find the cell face value a quadratic function passing through two bracketing or surrounding nodes and one node on the upstream side must be used.
23.
This discussion started from the definition of a parabola as a conic section, but it has now led to a description as a graph of a quadratic function.
24.
For linear and quadratic functions, the graph of any function can be obtained from the graph of the parent function by simple translations and stretches parallel to the axes.
25.
In this approximation, the vibrational energy is a quadratic function ( parabola ) with respect to the atomic displacements and the first overtone has twice the frequency of the fundamental.
26.
Pearson ( 1895, p . 367 ) distinguished two main cases, determined by the sign of the discriminant ( and hence the number of real roots ) of the quadratic function
27.
Further, for molecules larger than triatomic ones, it is quite common to introduce the harmonic approximation, which approximates the potential energy surface as a quadratic function of the atomic displacements.
28.
Regardless of the format, the graph of a univariate quadratic function f ( x ) = ax ^ 2 + bx + c is a parabola ( as shown at the right ).
29.
In a nonlinear elastic material the Young modulus is a function of the strain, so the second equivalence no longer holds and the elastic energy is not a quadratic function of the strain:
30.
Its polynomial time bound follows from the fact that each resolution step increases the number of clauses in the instance, which is upper bounded by a quadratic function of the number of variables.
