In this paper, iteration method of logistic map with low positions is introduced in order to investigate property of logistic map. Basic structure of logistic map is proposed, which consists of common gene positions (CGPs) and individual gene positions (IGPs). CGPs have the same value of corresponding positions which transferred from previous numerical solutions. The ergodicity and long-term unpredictability...
The numerical simulation of conventional air-cooled unit and a new air-cooled one in which the incoming air is swirled by adding a swirler under the different angles of vane in the swirler has been made by employing actual data of Longshan power plant based on FLUENT software. Flow fields of the two kinds of units are obtained and compared. The most appropriate angle of vane in the swirler for heat...
Open pit slope stability analysis by the uncertainty existing in the instructions, put forward the need for reliability calculation, and calculation of reliability are discussed for the partial derivative function and the function does not converge to the finite element calculations software and functional problems caused by function argument there was a correlation between this issue and do a thorough...
According to the incomplete clear mechanism of bolt support action presently, the bolt support parameter of 12910 face haulage roadway is given optimized design in HANDAN TAOYI mine by the analytic system software: ANSYS, using theory analysis, numerical simulation and engineering actual measurement. The surrounding rock failure region of the optimized roadway is 12.54m2, decreased by 31.0% compared...
The soft soil under the Lang-Cang Highway of Hebei province in china mainly consists of low liquid limit middle-high compressibility clay layer. In order to shorten construction period, reinforce the foundation directly and rapidly, increase mechanical strength and deformation modulus and decrease the total settlement, the static grouting method is used to strengthen the soft soil foundation. In this...
Ant colony algorithm (ACA) is a heuristic search algorithm to solve combinational optimization problems whose selection strategy has direct relations with the information content of the routes which is indefinite. Based on comparison of several improved algorithms, improved ACA based on comentropy is proposed in the paper. By controlling comentropy figure, route selection and the probability of local...
