Compared with conventional therapy techniques, sonodynamic therapy of atherosclerosis can achieve non-invasive radical treatment. Currently the treatment parameters are mostly determined empirically. This paper is to describe the establishment of ultrasonic propagation simulation model of atherosclerotic biological tissues by identifying and extracting the medical image feature, together with the...
Efficient distribution for emergency logistics is vital to alleviate the disaster impact after the occurrence of earthquake. This paper studies the distribution priority of different rescue resource. Using Risk Priority Number (RPN) methodology,a dynamic model for identifying the relief-demand urgency is built. In the new RPN model, the parameters are redefined and a set of weights are assigned to...
Textile and garment trade occupys an important position in our country. Article started from the amount of textile and garment exports using China's textile and garment export trade data, from 1992 to 2008. Based on the use of Holt model to predict the export in different stages. Result shows that the Holt model has a high prediction accuracy for predicting textile and garment exports. And predicted...
Entrepreneurial innovation is a very important driving force of economic development and a decisive factor for optimizing of social interests. Starting from the competitive exclusive and externality characteristics of entrepreneurial innovation, using the individual entrepreneurs' maximizing investment decision-making theory, the paper analyzes the relationship of entrepreneurial innovation inputs...
The objective of this paper is to compare the merits of back propagation neural network (BPNN) with those of cross-nested logit (CNL) model to estimate the simultaneously joint choice of residential location and commute mode choice during the process of employment surburbanization. Back propagation neural network and discrete choice model specified as cross-nested logit have been respectively employed...
In theory, the paper presents an Automated Negotiation Model by applying negotiation strategies and utility function. In methodology, the paper establishes a negotiation mechanism which can improve both the automated processing flow and the automated trade by using agent technology. At last, simulate the process of Electronic Commerce automated negotiation and analyze the output of the program on...
Statistic analyses were made based on the daily air pollution index data at five cities in Xinjiang of northwest of China from January 2005 to October 2008. Trajectory model (HYSPLIT4.8) was used to analysis the backward and forward trajectories on heavy air pollution days during winter of 2006. The results presented as following. 1) Winter is the season with the highest occurrence frequency of air...
In this paper, a new theoretical model for understanding the forming mechanism of pigmentation patterns has been proposed. It is found that a non-linearly coupled Turing system can exhibit complex patterns with more than one wavelength. Depending on the control parameters, three kinds of complex pigmentation including super-stripe, super-hexagon, and mixed pattern can be well understood.
More and more large amounts of data shared with researchers and workstations worldwide are generated by scientific experiments and engineering applications. High performance grids aim at facilitating the distribution of such data to geographically remote places. For high performance data grids where users require remote access to large files, dynamic replication is an efficient method to improve performance...
