CRS stack is a seismic imaging method that does not depend on a macro velocity model and only need to know near surface velocity and relies on three wavefield parameters.

Further, by using Lagrangian inversion to obtain a number of summation free formulae directly, the various kinds of rooted Halin maps with up to three parameters have been counted.

The problem of determining partial values of functions is solved in a graphic representation using the method of successive approximations, by variational selection of three parameters, namely, the height of peak, its position, and half-width.

The minimum levels of all three parameters (HR, BPs, and BPd) were increased during the first night shifts, which indicates that the effectiveness of CVS activation in the nighttime was decreased as compared to the daytime.

A measuring cell has been designed for fast preparation of multicomponent solutions and express characterization of them in three parameters: their electrical conductivity, optical density, and viscosity.

Analysis was performed with different values of three parameters isolated as major ones.

This paper discusses the interval estimations method for the parameters and other reliability characters of a three-parameter Weibull distribution.

The three-parameter Hill's equation, which is used in enzyme kinetics, was shown to be applicable to calibration curves of both potentiometric (glucose, pesticides, urea, etc.) and amperometric (surfactants, biphenyl, etc.) biosensors.

Based on statistical analysis and x~2 test of the field data, it is found that Gamma and Weibull distribution are suitable to express the distribution of wind wave run-up on slope, and the distribution parameters depend on relative depth and slope. According to the suggested theoretical distribution, the average values of the 1/n th highest wave run-up and the expected values of extreme for a sample of size N are computed while the results agree with the field data satisfactorily. Finally, an empirical expression...

By analyzing and comparing the calculated results, the effectiveness about the model of the 3-parameter lognormal distribution is demonstrated. The calculation and examination of the generated inflow sequences of the Fengman and Baishan Reservoirs, their inflow charactes being obviously different from that of the Danjiang Kou Reservoir, have been carried out with this kind of model. The results show that this model is of a certain generality.
