Nuclear physicists at the University of Washington developed a new framework to analyze how theoretical approximations ...

Matrix functions, such as the exponential, square root and cosine, play an indispensable role in various fields including quantum mechanics, control theory and numerical solution of differential ...

The FD= and FDHESSIAN= options specify the use of finite difference approximations of the derivatives. The FD= option specifies that all derivatives are approximated using function evaluations, and ...

Saddlepoint approximations are extended to general statistics. The technique is applied to derive approximations to the density of linear combinations of order statistics, including trimmed means. A ...

The theories of high speed aerodynamics described in this volume, on the basis of which a quantitative study of the characteristically “nonlinear” effects is made in the present section, are those ...
