The text puts forward that knowledge sharing possesses a complete ecological competitive attribute,and make a model of ecological competition about knowledge sharing in organizations based on a logistic equation of ecology consequently.

The organization crime system s logic and evolvement analysis;

In this paper,the basic theory for electromagnetic susceptibility data analysis using multivariate logistic regression is put forward,and the applied approach of the theory in the practice is introduced through a simple example.

Logistic models were established to describe growth in height, diameter and volume in the dominant trees of these forests at Gongga Mountain: Abies fabri, Picea brachytyla and A.

The recursion formula[N(t+s)]-1=α+β·[N(t)]-1 of Logistic models is derived from recursive analysi.

Logistic model is increasing model,its outstretched application in Xinjiang Kanasi Lake tour that establish theory foundation to study ecological tour scene.

Fitting Logistic Curve by Finding Minimum Residuals from Point to Point in Parameter Space;

Based on the previous studies, compensation subsidy for the values of non-marketable forest products was computed with a method of compensation coefficient that combines the Engel Coefficient and Logistic Curve.

By using Logistic curve,this paper builds the TV market developing model,uses methods of econometrics to estimate and test the parameters in the model,then discuss TV market developing trend basing on the caculating result of the model.

This paper puts forward a new approach to producing random numerals by making use of the Logistic Mapping and parabolic mapping model in chaotic mechanics.
