This paper proposes a new social network model - Preference Memory Network (PMN) to overcome the common deficiency that existing network models do not take into account the heterogeneity of nodes and the memory feature on node connections preference. Experimental results shows that Preference Memory Network model have small-world, scale-free, high clustering coefficient and short average shortest...
A skyhook control policy was selected and analyzed based on the character of Magneto-Rheological Fluids (MRF) Dampers, while the skyhook control model was established. A half roll plane vehicle model with 4DOF was simulation analyzed for the control strategy. The control method was investigated in two aspects including the vehicle ride comfort and handling stability through three basic input signals...
Adopting Hardening-Soil finite element model based on unloading ,the improvement of grouting strengthening rear soil on deformation of the pit is studied. The results show that the reinforce influence on lateral deformation increases with the increasing of the excavating depth, the final lateral deformation reduces 13.6% than without reinforce, the displacement of pile top reduces 40.66%, but the...
Prisoner's Dilemma, which is a basic model adopted by the vast majority of co-evolution researchers, not only is a classic paradigm for studying co-evolution but also is a classic paradigm of modern business management for researching the enterprises, between which there is competition and cooperation. In this paper, a dynamic model of spatial continuous Prisoner's Dilemma (CPD) will be suggested,...
Entering knowledge economic age, the amount of enterprise holding knowledge and the ability to develop and utilize knowledge have been the sharp weapon to deal with market competition and the ever source to develop continuously, and knowledge sharing is the most important part of knowledge management. With nonstandard employing knowledge workers more and more common, the knowledge sharing between...
The mounting bracket is one of the most important connecting components in commercial vehicle cab. The FEM provides guidance for maximizing the effectiveness of weight reduction efforts on condition that the structure meets the requirements for strength, stiffness and vibration performance. The work presents two kinds of structural optimization methods, which are topology optimization and size optimization...
Considering the asymmetry of return distributions and asymmetric impact of positive and negative returns on the quantiles, the paper puts forth a new conditional autoregressive value-at-risk by regression quantiles model with asymmetric absolute values and slops (AAVS-CAViaR) quantile specification for heavy-tail data applications. An empirical study on the evolution patterns of market risk of wheat...
With the methods of geometry, sites' structure of HF air-to-ground communications and the sites-setting methods are studied. It is intent on putting forward ways and means to allocate sites of HF air-to-ground communications efficiently. After proving the theory that coverage efficiency of circles with the same radius is higher than the coverage efficiency of circles with different radiuses, the optimal...
Recent years, nonstandard employment, special the nonstandard employing knowledge workers, has been coming an important method for organization to increase its flexible ability and competitive ability. However present literature show confusing results about its effectiveness, some show good effectiveness, and some show bad. Firstly this paper analyzes the nonstandard employing knowledge workers' effectiveness...
In this paper, a method is presented for connectively analyzing the dynamic factors in physical training by utilizing computers. Through analyzing the training results of a certain triple jumper, the thesis expounds how to build the mathematics models for the connective factors in system and it also presents the detailed procedure by utilizing these models to connectively analyze the dynamic changes...
