Let [LAMBDA] (P) be the set of characteristic functions over P.
Based on an overall consideration of three characteristic functions, there parameters have been used accordingly.
As we know, the characteristic function of the sum of independent random variables is equal to the product of the characteristic functions of each random variable .
Moreover, if we choose different general characteristic functions [phi], we can obtain different results.
In particular, the four functions are called the characteristic functions of an atomic model.
The deviation payoffs are given directly, which are related closely to the sufficient condition of strategic stability and avoid the loss of super-additivity of the general characteristic functions. Then we study the repeated infinite stage game (RISG).
Precision was modeled with characteristic functions to create higher imprecision close to the limits of detection.
Those generating functions are a predecessor of characteristic functions [10, page 286].
In order to achieve efficient BP measurements, three different characteristic functions are applied to compose the active pressure trajectory, including sigmoid functions, cosine functions, and third order polynomial functions.
Characteristic functions of the mobility [Y.sub.U](s) or the impedance [Z.sub.U](s), directly subjected to the synthesis method, are determined using the transformation in relation to the admittance [V.sub.U](s) or the stiffness [U.sub.U](s) in the form
