Frequently the need arises for the computer generation of variates that are exact/y distributed as 2 = max(X,, . , X.) where X,, . . . , X, form a sequence of independent identically distributed random variables. For large n the individual generation of the Xi’s is unfeasible, and the inversion-of-a-beta-variate is potentially inaccurate. In this paper, we discuss and compare the corrected inve...

In this paper we describe a new approach to shar p boundary geophy sical inversion. We demon strate that regularized inversion with a minimum support stabilizer can be implemented by using a specially designed nonl inear parametrization of the mode l parameters . Thi s parametrization plays the same role as transformation into the space of the weighted model parameters, introd uced in the origi...

The problem of inversion dynamic systems has become widespread while solving the problems control, identification, and measurement arising during design research electrical mechanical systems. Inverting is an effective way implementing disturbance control processes, as well in combined with a predictive model. analysis information sources showed that practical solution most problems, number dif...

In this study, a method is proposed to carry out automatic inversion of oblique ionograms extract the parameters and electron density profile ionosphere. The adopts quasi-parabolic segments (QPS) model represent Firstly, numerous candidate profiles corresponding vertical traces were, respectively, calculated synthesized by adjusting QPS model. Then, were transformed secant theorem Martyn’s equi...

Six forest tree height inversion methods of polarimetric SAR interferometry were validated using repeat pass E-SAR datasets and the corresponding ground measured forest stand height. We show that SINC, three stage full model and three stage SINC inversions have good performance, and the SINC inversion with the first optimum coherence (OPT1) produces the best result among the eleven coherence ty...
