Accuracy analysis of the semi-analytical method for shape sensitivity calculation
29th Structures, Structural Dynamics and Materials Conference, 1988The semianalytical method of design sensitivity analysis that is widely used for calculating derivatives of static response with respect to design variables for structures modeled by finite elements is studied. It is shown that the method can have serious accuracy problems for shape design variables in structures modeled by beam, plate, truss, frame ...

SEMI-ANALYTICAL SENSITIVITY METHODS FOR AEROELASTIC SHAPE OPTIMIZATION
Accurate and efficient sensitivity analysis is fundamental for the convergence of gradient-based optimization techniques. Analytical sensitivity methods are preferred over numerical ones for their accuracy and higher computational efficiency. Although analytical sensitivity methods have been developed for different static structural and purely ...Giuseppe Maurizio Gagliardi +2 more

A Semi-analytical Method for Finding the Roots of a Polynomial
IETE Journal of Education, 2014ABSTRACTA systematic method, which combines graphical, analytical, and numerical techniques, is presented for finding the roots of a polynomial P0(s) of any degree. Real roots are first found by a simple graphical method, and then the purely imaginary roots are found by the Hurwitz test.

A semi-analytic method for pole determination of asteroids
The Moon and the Planets, 1981A semi-analytic method, obtained collecting amplitude-aspect and magnitude-aspect relations, is given in order to deduce the pole coordinates of asteroids. The accuracy of this method (5–10°), which needs some restrictive hypotheses, seems to be sufficient for statistical purposes.

Analytical and Semi-analytical Methods in Transport Theory
1991It is not an entirely simple matter to describe when transport theory came into existence, or, indeed, what exactly does constitute transport theory. Certainly the term has been used at times interchangeably with kinetic theory. On the other hand, it does seem that the group of researchers who, over the past three or four decades, have identified ...
